2007 FINANCIAL RESULTS AND KEY CORPORATE INITIATIVES

Financial Results

•  Reported income from continuing operations of $682 million, or $4.40 per diluted share for 2007, compared to $782 million, or $4.81 per diluted share, for 2006. The most significant item contributing to the $100 million decrease in income from continuing operations in 2007, when compared to 2006, was an increase in the provision for loan losses of $175 million. Net income was $686 million, or $4.43 per diluted share for 2007, compared to $893 million, or $5.49 per diluted share for 2006. Included in net income in 2006 was a $108 million after-tax gain on the sale of the Corporation’s Munder subsidiary

•  Returned 13.52 percent on average common shareholders’ equity and 1.17 percent on average assets

•  Generated growth from December 31, 2006 to December 31, 2007 of $3.3 billion in loans and $1.3 billion in unused commitments to extend credit

•  Generated geographic market growth in average loans (excluding Financial Services Division) of seven percent from 2006 to 2007, including Texas (16 percent), Western (13 percent) and Florida (11 percent), with the Midwest market down one percent

•  Increased total revenue two percent, including four percent growth in noninterest income. Excluding a $47 million Financial Services Division-related lawsuit settlement and a $12 million loss on the sale of the Mexican bank charter in 2006, total revenue growth was three percent and noninterest income growth was eight percent

•  Contained the increase in noninterest expenses to $17 million, or one percent, from 2006. 2007 included incremental expenses related to new banking centers ($23 million), a charge related to the Corporation’s membership in Visa, Inc. (Visa) ($13 million) and costs associated with the previously announced headquarters move to Dallas, Texas ($6 million). 2006 noninterest expense included interest on tax liabilities of $38 million. Interest on tax liabilities was not classified in noninterest expenses in 2007, and instead classified in the “provision for income taxes”. Full-time equivalent employees increased less than one percent from 2006 to 2007, even with the addition of 30 new banking centers during the period

•  Incurred net credit-related charge-offs of 31 basis points as a percent of average total loans in 2007, compared to 15 basis points in 2006; nonperforming assets increased to $423 million, reflecting challenges in the residential real estate development industry in Michigan and California

•  Raised the quarterly cash dividend 8.5 percent, to $0.64 per share, an annual rate of $2.56 per share, for an annual dividend payout ratio of 58 percent

•  Repurchased 10 million shares of outstanding common stock in the open market for $580 million, which combined with dividends, returned 142 percent of earnings to shareholders

Key Corporate Initiatives

•  Relocated corporate headquarters to Dallas, Texas, where Comerica already had a major presence, to position the Corporation in a more central location with greater accessibility to all markets. Comerica is now the largest bank headquartered in Texas

•  Continued organic growth focused in high growth markets, including opening 30 new banking centers in 2007; in 2008, Comerica expects to open 32 new banking centers. Since the banking center expansion program began in late 2004, new banking centers have resulted in nearly $1.8 billion in new deposits

•  Continued to refine and develop the enterprise-wide risk management and compliance programs, including improvement of analytics, systems and reporting

•  Managed full-time equivalent staff growth to less than one percent, even with approximately 140 full-time equivalent employees added to support new banking center openings

•  Reduced automotive production exposure from loans, unused commitments and standby letters of credit and financial guarantees from $4.2 billion at December 31, 2006 to $3.7 billion at December 31, 2007

OVERVIEW/EARNINGS PERFORMANCE

Comerica Incorporated (the Corporation) is a financial holding company headquartered in Dallas, Texas. The Corporation’s major business segments are the Business Bank, the Retail Bank and Wealth & Institutional Management. The core businesses are tailored to each of the Corporation’s four primary geographic markets: Midwest, Western, Texas and Florida.

The accounting and reporting policies of the Corporation and its subsidiaries conform to U.S. generally accepted accounting principles and prevailing practices within the banking industry. The Corporation’s consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described on page 72 in Note 1 to the consolidated financial statements. The most critical of these significant accounting policies are discussed in the “Critical Accounting Policies” section on page 62 of this financial review.

As a financial institution, the Corporation’s principal activity is lending to and accepting deposits from businesses and individuals. The primary source of revenue is net interest income, which is derived principally from the difference between interest earned on loans and investment securities and interest paid on deposits and other funding sources. The Corporation also provides other products and services that meet the financial needs of customers and which generate noninterest income, the Corporation’s secondary source of revenue. Growth in loans, deposits and noninterest income is affected by many factors, including the economic growth in the markets the Corporation serves, the financial requirements and health of customers and successfully adding new customersand/or increasing the number of products used by current customers. Success in providing products and services depends on the financial needs of customers and the types of products desired.

The Corporation sold its stake in Munder Capital Management (Munder) in 2006. This financial review and the consolidated financial statements reflect Munder as a discontinued operation in all periods presented. For detailed information concerning the sale of Munder and the components of discontinued operations, refer to Note 26 to the consolidated financial statements on page 127.

The remaining discussion and analysis of the Corporation’s results of operations is based on results from continuing operations.

The Corporation generated growth of $3.3 billion in loans and $1.3 billion in unused commitments to extend credit from December 31, 2006 to December 31, 2007. Excluding Financial Services Division, nearly all business lines showed average loan growth in 2007, compared to 2006, including Specialty Businesses, which includes Entertainment, Energy, Leasing, and Technology and Life Sciences (17 percent), Global Corporate Banking (12 percent), Private Banking (11 percent), National Dealer Services (5 percent), Commercial Real Estate (5 percent), Small Business (5 percent) and Middle Market (5 percent). Excluding Financial Services Division, average loans grew in the Texas (16 percent), Western (13 percent) and Florida (11 percent) geographic markets in 2007, compared to 2006, and declined one percent in the Midwest market. Average loans decreased 44 percent in 2007 in the Financial Services Division, where 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. Average deposits excluding Financial Services Division increased $1.9 billion, or five percent from 2006. The increase in average deposits excluding Financial Services Division when compared to 2006, resulted primarily from an increase in customer and institutional certificates of deposit. Average Financial Services Division deposits decreased $2.0 billion, or 34 percent, in 2007, compared to 2006. The decrease in average Financial Services Division deposits in 2007, when compared to 2006, resulted from a $1.5 billion decrease in average noninterest-bearing deposits and a $508 million decrease in average interest-bearing deposits. Noninterest-bearing deposits in the Corporation’s Financial Services Division include title and escrow deposits, which benefit from home mortgage financing and refinancing activity. Financial Services Division deposit levels may change with the direction of mortgage activity changes, the desirability of such deposits and competition for deposits. Net interest income increased one percent in 2007, compared to 2006, primarily due to loan growth.

Noninterest income, excluding net securities gains, net gain (loss) on sales of businesses and income from lawsuit settlement, increased seven percent in 2007, compared to 2006, resulting primarily from increases in fiduciary income ($19 million), commercial lending fees ($10 million), income from principal investing and warrants ($9 million) and card fees ($8 million).

21

The Corporation’s credit staff closely monitors the financial health of lending customers in order to assess ability to repay and to adequately provide for expected losses. Loan quality was impacted by challenges in the residential real estate development industry in Michigan and California and a leveling off of overall credit quality improvement trends in the Texas market and remaining businesses in the Western market. Credit quality trends resulted in an increase in net credit-related charge-offs and nonperforming assets in 2007, compared to 2006. The tools developed in the past several years for evaluating the adequacy of the allowance for loan losses, and the resulting information gained from these processes, continue to help the Corporation monitor and manage credit risk.

Noninterest expenses increased one percent in 2007, compared to 2006, primarily due to increases in net occupancy and equipment expense ($18 million), regular salaries ($16 million) and a charge related to the Corporation’s membership in Visa ($13 million), partially offset by a decrease resulting from the prospective change in the classification of interest on tax liabilities to “provision for income taxes” on the consolidated statements of income effective January 1, 2007. Noninterest expenses included $38 million of interest on tax liabilities in 2006. The $18 million increase in net occupancy and equipment expense in 2007 included $9 million from the addition of 30 new banking centers. Full-time equivalent employees increased by less than one percent (approximately 80 employees) from year-end 2006 to year-end 2007, even with approximately 140 full-time equivalent employees added to support new banking center openings.

A majority of the Corporation’s revenues are generated by the Business Bank business segment, making the Corporation highly sensitive to changes in the business environment in its primary geographic markets. To facilitate better balance among business segments and geographic markets, the Corporation opened 30 new banking centers in 2007 in markets with favorable demographics and plans to continue banking center expansion in these markets. This is expected to provide opportunity for growth across all business segments, especially in the Retail Bank and Wealth & Institutional Management segments, as the Corporation penetrates existing relationships through cross-selling and develops new relationships.

For 2008, management expects the following, compared to 2007 from continuing operations (assumes the economy experiences slow growth in 2007 rather than a recession):

•  Mid to high single-digit average loan growth, excluding Financial Services Division loans, with flat growth in the Midwest market, high single-digit growth in the Western market and low double-digit growth in the Texas market

•  Average earning asset growth in excess of average loan growth

•  Average Financial Services Division noninterest-bearing deposits of $1.2 to $1.4 billion. Financial Services Division loans will fluctuate in tandem with the level of noninterest-bearing deposits

•  Based on the federal funds rate declining to 2.00 percent by mid-year 2008, average full year net interest margin between 3.10 and 3.15 percent, including the effects of higher levels of securities, lower value of noninterest-bearing deposits, average loan growth exceeding average deposit growth and the 2008 FAS 91 impact discussed below

•  Average net credit-related charge-offs between 45 and 50 basis points of average loans, with charge-offs in the first half higher than in the second half of 2008. The provision for credit losses is expected to exceed net charge-offs

•  Low single-digit growth in noninterest income

•  Low single-digit decline in noninterest expenses, excluding the provision for credit losses on lending-related commitments and including the 2008 FAS 91 impact discussed below

•  Effective tax rate of about 32 percent

•  Maintain a Tier one common capital ratio comparable to year-end 2007

•  Statement of Financial Accounting Standards No. 91 (FAS 91) - Accounting for Loan Origination Fees and Costs. Beginning in 2008, a change in the application of FAS 91 will result in deferral and amortization (over the loan life) to net interest income of more fees and costs. Based on assumptions for loan growth, loan fees and average loan life, the estimated impact on 2008, compared to 2007, will be to lower the net interest margin by about 3-4 basis points (approximately $20 million), lower noninterest expenses by about 3-4 percent (approximately $60 million) and increase earnings per share by about four cents per quarter

Net Interest Income

Net interest income is the difference between interest and yield-related fees earned on assets and interest paid on liabilities. Adjustments are made to the yields on tax-exempt assets in order to present tax-exempt income and fully taxable income on a comparable basis. Gains and losses related to the effective portion of risk management interest rate swaps that qualify as hedges are included with the interest income or expense of the hedged item when classified in net interest income. Net interest income on a fully taxable equivalent (FTE) basis comprised 69 percent of total revenues in 2007, compared to 70 percent in 2006 and 71 percent in 2005. Table 2 on page 23 of

24

this financial review provides an analysis of net interest income for the years ended December 31, 2007, 2006 and 2005. The rate-volume analysis in Table 3 above details the components of the change in net interest income on a FTE basis for 2007 compared to 2006 and 2006 compared to 2005.

Net interest income (FTE) was $2.0 billion in 2007, an increase of $20 million, or one percent, from 2006. The net interest margin (FTE), which is net interest income (FTE) expressed as a percentage of average earning assets, decreased to 3.66 percent in 2007, from 3.79 percent in 2006. The increase in net interest income in 2007 was due to loan growth, which was partially offset by a decline in noninterest-bearing deposits (primarily in the Financial Services Division) and competitive environments for both loan and deposit pricing. The decrease in net interest margin (FTE) was due to loan growth, a competitive loan and deposit pricing environment and changes in the funding mix, including a continued shift in funding sources toward higher-cost funds. Partially offsetting these decreases were maturities of interest rate swaps that carried negative spreads, which provided a 10 basis point improvement to the net interest margin in 2007, compared to 2006. Average earning assets increased $2.4 billion, or five percent, to $54.7 billion in 2007, compared to 2006, primarily as a result of a $2.1 billion increase in average loans and a $455 million increase in average investment securities available-for-sale. Average Financial Services Division loans (primarily low-rate) decreased $1.0 billion, and average Financial Services Division noninterest-bearing deposits decreased $1.5 billion in 2007, compared to 2006.

The Corporation expects, on average, net interest margin in 2008 to be between 3.10 and 3.15 percent for the full year, based on the federal funds rate declining to 2.00 percent by mid-year 2008 and including the effects of higher levels of securities, lower value of noninterest-bearing deposits, average loan growth exceeding average deposit growth and the 2008 FAS 91 impact discussed in the 2008 guidance provided on page 22 of this financial review.

Net interest income and net interest margin are impacted by the operations of the Corporation’s Financial Services Division. 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 2 on page 23 of this financial review displays average Financial Services Division loans and deposits, with related interest income/expense and average rates. As shown in Footnote (2) to Table 2 on page 23 of this financial review, 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 8 basis points in 2007, compared to a decrease of 16 basis points in 2006.

The Corporation implements various asset and liability management tactics to manage net interest income exposure to interest rate risk. Refer to the “Interest Rate Risk” section on page 54 of this financial review for additional information regarding the Corporation’s asset and liability management policies.

In 2006, net interest income (FTE) was $2.0 billion, an increase of $26 million, or one percent, from 2005. The net interest margin (FTE) decreased to 3.79 percent in 2006, from 4.06 percent in 2005. The increase in net interest income in 2006 was due to strong loan growth, which was nearly offset by a decline in noninterest-bearing deposits (primarily in the Financial Services Division), competitive environments for both loan and deposit pricing and the impact of warrant accounting change discussed in Note 1 to the consolidated financial statements on page 72, which resulted in a $20 million increase in net interest income in 2005. A greater contribution from noninterest-bearing deposits in a higher rate environment also benefited net interest income in 2006. The decrease in net interest margin (FTE) was due to the 2005 warrant accounting change, which increased the 2005 net interest margin by four basis points, the changes in average Financial Services Division loans and noninterest-bearing deposits discussed below, competitive loan and deposit pricing, a change in the interest-bearing deposit mix toward higher-cost deposits and the margin impact of loan growth funded with non-core deposits and purchased funds. Average earning assets increased $4.1 billion, or eight percent, to $52.3 billion in 2006, compared to 2005, primarily as a result of a $3.9 billion increase in average loans and a $131 million increase in average investment securities available-for-sale. Average Financial Services Division loans (primarily low-rate) increased $470 million, and average Financial Services Division noninterest-bearing deposits decreased $1.5 billion in 2006, compared to 2005.

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 reflects management’s evaluation of the adequacy of the allowance for loan losses. The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The provision for credit losses on lending-related commitments, a component of “noninterest expenses” on the consolidated statements of income, reflects management’s assessment of the adequacy of the allowance for credit losses on lending-related commitments. The allowance for credit losses on lending-related commitments, which is included in “accrued expenses and other liabilities” on the consolidated balance sheets, covers probable credit-related losses inherent in credit-related commitments, including letters of credit and financial guarantees. The Corporation performs an in-depth quarterly credit quality review to determine the adequacy of both allowances. For a further discussion of both the allowance for loan losses and the allowance for credit losses on lending-related commitments, refer to the “Credit Risk” section of this financial review on page 44, and the “Critical Accounting Policies” section on page 62 of this financial review.

The provision for loan losses was $212 million in 2007, compared to $37 million in 2006 and a negative provision of $47 million in 2005. The $175 million increase in the provision for loan losses in 2007, compared to 2006, resulted primarily from challenges in the residential real estate development industry in Michigan and California and a leveling off of overall credit quality improvement trends in the Texas market and the remaining businesses of the Western market. These credit trends reflect economic conditions in the Corporation’s three largest geographic markets. While the economic conditions in Michigan deteriorated over the last year, the economic conditions in Texas continued to experience growth at a rate somewhat faster than the national economy, while those in California, other than real estate, grew at a rate equal to the nation as a whole. The average 2007 Michigan Business Activity index compiled by the Corporation was slightly lower than the average for 2006. However, intense restructuring efforts in the Michigan-based automotive sector created a significant drag on the state economy that spilled over to other sectors, with the residential real estate development industry one of the most affected. Forward-looking indicators suggest that current economic conditions in Michigan will deteriorate at about the same pace as in 2007 and that growth in California and Texas will be slower than it was last year. The increase in the provision for loan losses in 2006, when compared to 2005, was primarily the result of loan growth, challenges in the automotive industry and the Michigan residential real estate development industry, and a leveling off of credit quality improvement trends.

The provision for credit losses on lending-related commitments was a negative provision of $1 million in 2007, compared to charges of $5 million and $18 million in 2006 and 2005, respectively. The $6 million decrease in the provision for credit losses on lending-related commitments in 2007 was primarily the result of a decrease in specific reserves related to unused commitments extended to two large customers in the automotive industry. These reserves declined due to sales of commitments and improved market values for the remaining commitments. The decrease in 2006 was primarily due to reduced reserve needs resulting from improved market values for unfunded commitments to certain customers in the automotive industry. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.

Net loan charge-offs in 2007 were $149 million, or 0.30 percent of average total loans, compared to $60 million, or 0.13 percent, in 2006 and $110 million, or 0.25 percent, in 2005. The $89 million increase from 2006 resulted primarily from increases in Midwest residential real estate development ($43 million), Midwest middle market lending ($34 million) and Western residential real estate development ($16 million). Total net credit-related charge-offs, which includes net charge-offs on both loans and lending-related commitments, were $153 million, or 0.31 percent of average total loans, in 2007, compared to $72 million, or 0.15 percent, in 2006 and $116 million, or 0.26 percent, in 2005. Of the $81 million increase in net credit-related charge-offs in 2007, compared to 2006, net credit-related charge-offs in the Business Bank business segment increased $80 million. By geographic market, net credit-related charge-offs in the Midwest and Western markets increased $62 million and $27 million in 2007 compared to 2006. Net credit-related charge-offs in 2006 were impacted by a decision to sell a $74 million portfolio of loans related to manufactured housing. These loans were transferred to held-for-sale in the fourth quarter 2006, which required a charge-off of $9 million to adjust the loans to estimated fair value. An analysis of the changes in the allowance for loan losses, including charge-offs and recoveries by loan category, is presented in Table 8 on page 45 of this financial review. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.

26

Management expects full-year 2008 average net credit-related charge-offs between 45 and 50 basis points of average loans, with charge-offs in the first half higher than in the second half of 2008. The provision for credit losses is expected to exceed net charge-offs.

Noninterest income increased $33 million, or four percent, to $888 million in 2007, compared to $855 million in 2006, and increased $36 million, or five percent, in 2006, compared to $819 million in 2005. Excluding net securities gains, net gain (loss) on sales of businesses and income from lawsuit settlement, noninterest income increased seven percent in 2007 and less than one percent in 2006. An analysis of increases and decreases by individual line item is presented below.

Service charges on deposit accounts increased $3 million, or one percent, to $221 million in 2007, compared to $218 million in both 2006 and 2005.

Fiduciary income increased $19 million, or 11 percent, in 2007 and increased $6 million, or four percent, in 2006. Personal and institutional trust fees are the two major components of fiduciary income. These fees are based on services provided and assets managed. Fluctuations in the market values of the underlying assets managed, which include both equity and fixed income securities, impact fiduciary income. The increase in 2007 and 2006 was due to net new business and market appreciation.

Commercial lending fees increased $10 million, or 16 percent, in 2007, compared to an increase of $2 million, or two percent, in 2006. The increases in 2007 and 2006 were primarily due to higher commercial loan commitment and participation fees.

Letter of credit fees decreased $1 million, or two percent, in 2007, compared to a decrease of $6 million, or eight percent, in 2006. The 2007 decrease in letter of credit fees was principally due to competitive pricing pressures and lower demand resulting from the recent challenges in the residential real estate market. Of the 2006 decline, $3 million reflected the impact, in 2005, of an adjustment of deferred fee amortization to more closely align the amortization periods with actual terms of the letters of credit.

Foreign exchange income increased $2 million, or five percent, to $40 million in 2007, compared to $38 million and $37 million in 2006 and 2005, respectively. The increase in 2007 was primarily due to the impact of exchange rate changes on the Canadian dollar denominated net assets held at the Corporation’s Canadian branch.

Brokerage fees of $43 million increased $3 million, or nine percent, in 2007, compared to $40 million and $36 million in 2006 and 2005, respectively. Brokerage fees include commissions from retail broker transactions

27

and mutual fund sales and are subject to changes in the level of market activity. The increase in 2007 was primarily due to increased customer investments in money market mutual funds. The increase in 2006 was primarily due to increased transaction volumes as a result of improved market conditions.

Card fees, which consist primarily of interchange fees earned on debit and commercial cards, increased $8 million, or 16 percent, to $54 million, compared to $46 million in 2006, and increased $7 million, or 17 percent, compared to $39 million in 2005. Growth in both 2007 and 2006 resulted primarily from an increase in transaction volume caused by the continued shift to electronic banking, new customer accounts and new products.

Bank-owned life insurance income decreased $4 million, to $36 million in 2007, compared to an increase of $2 million, to $40 million in 2006. The decrease in 2007 resulted primarily from a decrease in death benefits received and decreased earnings, as a result of interest rate changes.

Net income from principal investing and warrants increased $9 million to $19 million in 2007, compared to $10 million in 2006 and $17 million in 2005. The $9 million increase in 2007 included a $5 million increase in warrant income and $4 million of additional income generated from the Corporation’s indirect private equity investments.

Net securities gains were $7 million in 2007, none of which were individually significant, and were minimal in both 2006 and 2005.

The net gain (loss) on sales of businesses in 2007 included a net gain of $1 million on the sale of an insurance subsidiary and a $2 million adjustment to reduce the loss on the 2006 sale of the Corporation’s Mexican bank charter, while 2006 included a net loss of $12 million on the sale of the Mexican bank charter.

The income from lawsuit settlement of $47 million in 2006 resulted from a payment received to settle a Financial Services Division-related lawsuit in the fourth quarter 2006.

Other noninterest income increased $9 million, or eight percent, in 2007, compared to a decrease of $7 million, or five percent, in 2006. The following table illustrates fluctuations in certain categories included in “other noninterest income” on the consolidated statements of income.

Increases in regular salaries ($16 million), net occupancy and equipment expenses ($18 million), employee benefits ($9 million), and a $13 million charge in 2007 related to the Corporation’s membership in Visa, were substantially offset by a decrease due to the prospective change in classification of interest on tax liabilities to “provision for income taxes” in 2007 ($38 million). For further discussion of interest on tax liabilities, refer to Note 1 to the consolidated financial statements on page 72 and to the section in this financial review entitled “Income Taxes and Tax-Related Items.” In addition, noninterest expenses included approximately $6 million of costs related to the 2007 relocation of the Corporation’s headquarters to Dallas, Texas, reflected in salaries and other noninterest expenses. An analysis of increases and decreases by individual line item is presented below.

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

Salaries expense increased $21 million, or three percent, in 2007, compared to an increase of $37 million, or five percent, in 2006. The increase in 2007 was primarily due to increases in regular salaries of $16 million and incentive compensation of $4 million. The increase in regular salaries in 2007 was primarily the result of annual merit increases of approximately $18 million, partially offset by a decline in contract labor costs associated with technology-related projects. In addition, staff size increased approximately 80 full-time equivalent employees

29

from year-end 2006 to year-end 2007, including approximately 140 full-time equivalent employees added in new banking centers. The increase in incentive compensation was primarily due to increased incentives tied to peer-based comparisons of corporate results. Severance included $2 million in 2007 related to the relocation of the Corporation’s headquarters to Dallas, Texas. The increase in 2006 was primarily due to increases in regular salaries of $37 million and shared-based compensation of $14 million. The increase in regular salaries in 2006 was primarily the result of annual merit increases of approximately $17 million and increased contract labor costs associated with technology-related projects. In addition, staff size from continuing operations increased approximately 65 full-time equivalent employees from year-end 2005 to year-end 2006. Shared-based compensation expense increased in 2006 primarily as a result of adopting the requisite service period provisions of SFAS 123 (revised 2004) (SFAS 123(R)), “Shared-Based Payment,” effective January 1, 2006, as discussed in Notes 1 and 15 to the consolidated financial statements on pages 72 and 95, respectively. These increases were partially offset by a $16 million decline in incentives.

Employee benefits expense increased $9 million, or five percent, in 2007, compared to an increase of $6 million, or three percent, in 2006. The increase in 2007 resulted primarily from an increase in defined contribution plan expense, mostly from a change in the Corporation’s core matching contribution rate effective January 1, 2007. The increase in 2006 resulted primarily from an increase in pension expense. For a further discussion of pension and defined contribution plan expense, refer to the “Critical Accounting Policies” on page 62 of this financial review and Note 16 to the consolidated financial statements on page 97.

Net occupancy and equipment expense increased $18 million, or ten percent, to $198 million in 2007, compared to an increase of $9 million, or six percent, in 2006. Net occupancy and equipment expense increased $9 million and $7 million in 2007 and 2006, respectively, due to the addition of 30 new banking centers in 2007, 25 in 2006 and 18 in 2005.

Outside processing fee expense increased $6 million, or seven percent, to $91 million in 2007, from $85 million in 2006, compared to an increase of $8 million, or 10 percent, in 2006. The 2007 increase is from higher volume in activity-based processing charges, in part related to outsourcing. The 2006 increase in outside processing fees resulted primarily from the outsourcing of certain trust and retirement services processing and a new electronic bill payment service marketed to corporate customers in 2006.

Software expense increased $7 million, or 12 percent, in 2007, compared to an increase of $7 million, or 15 percent in 2006. The increases in both 2007 and 2006 were primarily due to increased investments in technology and the implementation of several systems, including tools for a sales tracking system in the banking centers, anti-money laundering initiatives and a corporate banking portal, increasing both amortization and maintenance costs.

Customer services expense decreased $4 million, or seven percent, to $43 million in 2007, from $47 million in 2006, and decreased $22 million, or 33 percent, in 2006, from $69 million in 2005. Customer services expense represents compensation provided to customers, and is one method to attract and retain title and escrow deposits in the Financial Services Division. The amount of customer services expense varies from period to period as a result of changes in the level of noninterest-bearing deposits and low-rate loans in the Financial Services Division and the earnings credit allowances provided on these deposits, as well as a competitive environment.

Litigation and operational losses increased $7 million, or 55 percent, to $18 million in 2007, from $11 million in 2006, and decreased $3 million, or 17 percent, in 2006, compared to $14 million in 2005. Litigation and operational losses include traditionally defined operating losses, such as fraud or processing problems, as well as uninsured losses and litigation losses. These expenses are subject to fluctuation due to timing of authorized and actual litigation settlements as well as insurance settlements. The increase in 2007 reflected $13 million to record an estimated liability related to membership in Visa, partially offset by a litigation-related insurance settlement of $8 million received in the second quarter 2007. Members of the Visa card association participate in a loss sharing arrangement to allocate financial responsibilities arising from any potential adverse resolution of certain antitrust lawsuits challenging the practices of the association. The Corporation believes that its share of the proceeds from an expected initial public offering of Visa, anticipated in early 2008, will exceed its share of recorded losses.

The provision for credit losses on lending-related commitments was a negative provision of $1 million in 2007, compared to provisions of $5 million and $18 million in 2006 and 2005, respectively. For additional

30

information on the provision for credit losses on lending-related commitments, refer to Notes 1 and 20 to the consolidated financial statements on pages 72 and 107, respectively, and the “Provision for Credit Losses” section on page 26 of this financial review.

Other noninterest expenses decreased $41 million, or 14 percent, in 2007, compared to an increase of $32 million, or 13 percent, in 2006. The decrease in 2007 was primarily the result of the prospective change in classification of interest on tax liabilities to “provision for income taxes” in 2007. The following table illustrates the fluctuations in certain categories included in “other noninterest expenses” on the consolidated statements of income. For a further discussion of interest on tax liabilities, refer to “Income Taxes and Tax-Related Items” below.

N/A- Not Applicable

Management expects a low single-digit decline in noninterest expenses in 2008 compared to 2007 levels, excluding the provision for credit losses on lending-related commitments and including the impact of a 2008 change in the application of FAS 91 discussed in the 2008 guidance provided on page 22 of this financial review.

The Corporation’s efficiency ratio (total noninterest expenses as a percentage of total revenue (FTE) excluding net securities gains) decreased to 58.58 percent in 2007, compared to 58.92 percent in 2006 and 58.01 percent in 2005. The efficiency ratio declined in 2007 primarily due to increased income levels and increased in 2006 primarily due to higher expense levels.

Income Taxes And Tax-Related Items

The provision for income taxes was $306 million in 2007, compared to $345 million in 2006 and $393 million in 2005. The provision for income tax in 2007 included a $9 million reduction ($6 million after-tax) of interest resulting from a settlement with the Internal Revenue Service (IRS) on a refund claim. The provision for income taxes in 2006 was impacted by the completion of an IRS audit of federal tax returns for years 1996 through 2000, the settlement of various refund claims and an adjustment to tax reserves. In the first quarter 2006, tax reserves, which include the provision for income taxes and interest expense on tax liabilities (included in “other noninterest expenses” in 2006 and 2005) 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. Interest on tax liabilities was also reduced by $6 million in the second quarter 2006, upon settlement of various refund claims with the IRS. As previously disclosed in quarterly and annual SEC filings under the heading “Tax Contingency,” the IRS disallowed the benefits related to a series of loans to foreign borrowers. The Corporation has had ongoing discussions with the IRS related to the disallowance. In the fourth quarter 2006, based on settlements discussed, the Corporation recorded a charge to its tax reserves for the disallowed loan benefits. The following table summarizes the impact of the items described above on the Corporation’s consolidated statement of income for the year ended December 31, 2006.

The effective tax rate, computed by dividing the provision for income taxes by income from continuing operations before income taxes, was 31.0 percent in 2007, 30.6 percent in 2006 and 32.5 percent in 2005. Changes in the effective tax rate in 2007 from 2006, and 2006 from 2005, are disclosed in Note 17 to the consolidated financial statements on page 103. The Corporation had a net deferred tax liability of $146 million at December 31, 2007. Included in net deferred taxes at December 31, 2007 were deferred tax assets of $514 million, net of a $2 million valuation allowance established for certain state deferred tax assets. A valuation allowance is provided when it is “more-likely-than-not” that some portion of the deferred tax asset will not be realized. Deferred tax assets are evaluated for realization based on available evidence and assumptions made regarding future events. In the event that the future taxable income does not occur in the manner anticipated, other initiatives could be undertaken to preclude the need to recognize a valuation allowance against the deferred tax asset.

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). As a result, the Corporation recognized an increase in the liability for unrecognized tax benefits of approximately $18 million at January 1, 2007, accounted for as a change in accounting principle via a decrease to the opening balance of retained earnings ($13 million net of tax). Prior disclosures on the change in unrecognized tax benefits resulting from the adoption of FIN 48 were adjusted to address an uncertain tax position that was incorrectly assessed at the time of adoption. The facts and circumstances surrounding this uncertain tax position were unchanged since January 1, 2007. For further discussion of FIN 48 refer to Note 17 to the consolidated financial statements on page 103.

In July, 2007, the State of Michigan replaced its current Single Business Tax (SBT) with a new Michigan Business Tax (MBT). Financial institutions are subject to an industry-specific tax which is based on net capital, effective January 1, 2008. Management believes the MBT will have an immaterial effect on the Corporation’s financial condition and results of operations when compared to the SBT. Both the SBT and MBT, when effective, are recorded in “Other noninterest expenses” on the consolidated statements of income.

Management expects an effective tax rate for the full-year 2008 of about 32 percent.

Income From Discontinued Operations, Net Of Tax

Income from discontinued operations, net of tax, was $4 million in 2007, compared to $111 million in 2006 and $45 million in 2005. Income from discontinued operations in 2007 reflected an adjustment to the initial gain recorded on the sale of the Corporation’s Munder subsidiary in 2006. Included in 2006 was a $108 million after-tax gain on the sale of Munder in the fourth quarter 2006. The Munder sale agreement included an interest-bearing contingent note with an initial principal amount of $70 million, which will be realized if the Corporation’s client-related revenues earned by Munder remain consistent with 2006 levels of approximately $17 million per year for the five years following the closing of the transaction(2007-2011). Future gains related to the contingent note are expected to be recognized periodically as targets for the Corporation’s client-related revenues earned by Munder are achieved. The potential future gains are expected to be recorded between 2008 and the fourth quarter of 2011, unless fully earned prior to that time. Included in 2005 was a $32 million after-tax gain in the fourth quarter 2005 that resulted from Munder’s sale of its minority interest in Framlington Group Limited (Framlington) (a London, England based investment manager). For further information on discontinued operations, refer to Note 26 to the consolidated financial statements on page 127.

STRATEGIC LINES OF BUSINESS

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 upon the products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Other category includes discontinued operations and items not directly associated with these business segments or the Finance Division. Note 24 to the consolidated financial statements on page 119 describes the business activities of each business segment and the methodologies which form the basis for these results, and presents financial results of these business segments for the years ended December 31, 2007, 2006 and 2005.

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

	Years Ended December 31
	2007				2006					2005
	(dollar amounts in millions)
Business Bank	$	503	75	%	$	589		74	%	$	658		74	%

Total	$	686			$	893				$	861

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

The Business Bank’s net income decreased $86 million, or 15 percent, to $503 million in 2007, compared to a decrease of $69 million, or 11 percent, to $589 million in 2006. Net interest income (FTE) was $1.3 billion in 2007, an increase of $11 million, or one percent, compared to 2006. The increase in net interest income (FTE) was primarily due to a $2.7 billion increase in average loan balances (excluding Financial Services Division) and a $524 million increase in average deposit balances (excluding Financial Services Division), partially offset by a decline in loan and deposit spreads. The provision for loan losses increased $164 million in 2007, from $14 million in 2006, primarily due to an increase in reserves in 2007 for the residential real estate development business, a reserve related to a single customer in the Technology and Life Sciences business line and credit improvements recognized in 2006, partially offset by a decrease in reserves related to the automotive industry in 2007. Excluding a $47 million Financial Services Division-related lawsuit settlement recorded in 2006 and a $12 million loss on the sale of the Mexican bank charter in 2006, noninterest income increased $21 million from 2006. The increase was primarily due to net securities gains of $7 million in 2007 and increases in commercial lending fees ($7 million) and card fees ($4 million) in 2007, when compared to 2006. Noninterest expenses of $708 million for 2007 decreased $33 million from 2006, primarily due to a $16 million decrease in allocated net corporate overhead expense, an $8 million decrease in provision for credit losses on lending-related commitments, and $8 million in legal fees recorded in 2006 related to the Financial Services Division-related lawsuit settlement noted previously. The corporate overhead allocation rates used were six percent and seven percent in 2007 and 2006, respectively. The one percentage point decrease in rate in 2007, when compared to 2006, resulted mostly from income tax related items.

The Retail Bank’s net income decreased $45 million, or 31 percent, to $99 million in 2007, compared to a decrease of $30 million, or 18 percent, to $144 million in 2006. Net interest income (FTE) of $627 million decreased $10 million, or two percent, in 2007, primarily due to decreases in loan and deposit spreads, partially offset by the benefit of a $349 million increase in average deposit balances. The provision for loan losses increased $18 million in 2007 primarily due to increases in credit-related reserves for Small Business Administration (SBA) loans and Small Business lending. Noninterest income of $220 million increased $10 million from 2006, primarily due to a $3 million increase in card fees and a $2 million increase in income from the sale of SBA loans. Noninterest expenses of

33

$655 million for 2007 increased $47 million from 2006, partially due to increases in salaries and employee benefits expense ($17 million), net occupancy expenses ($9 million) primarily related to the addition of new banking centers, outside processing fees ($5 million) and a charge related to the Corporation’s membership in Visa ($13 million). Partially offsetting these increases was an $8 million decrease in allocated net corporate overhead expenses. Refer to the Business Bank discussion above for an explanation of the decrease in allocated net corporate overhead expenses. The Corporation opened 30 new banking centers in 2007 and 25 new banking centers in 2006, contributing $56 million to noninterest expenses in 2007, an increase of $23 million compared to 2006.

Wealth & Institutional Management’s net income increased $9 million, or 14 percent, to $70 million in 2007, compared to a decrease of $2 million, or three percent, to $61 million in 2006. Net interest income (FTE) of $145 million decreased $2 million, or two percent, in 2007, compared to 2006, as decreases in loan spreads and average deposit balances were partially offset by an increase in average loan balances of $403 million from 2006. The provision for loan losses decreased $4 million, primarily due to an improvement from one large customer in the Midwest market. Noninterest income of $283 million increased $24 million, or 10 percent, in 2007, primarily due to a $19 million increase in fiduciary income and a $3 million increase in brokerage fees. Noninterest expenses of $322 million increased $9 million from 2006, primarily due to a $7 million increase in salaries and employee benefits expense and a $3 million increase in outside processing fee expense, partially offset by a $4 million decrease in allocated net corporate overhead expenses. Refer to the Business Bank discussion above for an explanation of the decrease in allocated net corporate overhead expenses.

Net income in the Finance Division was $4 million in 2007, compared to a net loss of $18 million in 2006. Contributing to the increase in net income was a $31 million increase in net interest income (FTE), primarily due to the rising rate environment in the first three quarters of the year, during which time interest income received from the lending-related business units increased faster than the longer-term value attributed to deposits generated by the business units, and the maturity of swaps with negative spreads, partially offset by an increase in wholesale funding.

Net income in the Other category was $10 million for 2007, compared to $117 million for 2006. Income from discontinued operations, net of tax, was $4 million in 2007, compared to $111 million for 2006. Discontinued operations in 2006 included a $108 million after-tax gain on the sale of the Corporation’s Munder subsidiary. Noninterest income increased $12 million from 2006, primarily due to a $4 million increase in net income from principal investing and warrants and a $4 million increase in deferred compensation asset returns. The remaining difference is 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.

Geographic 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. The Finance & Other Businesses category includes discontinued operations. Note 24 to the consolidated financial statements on page 119 presents a description of each of these market segments as well as the financial results for the years ended December 31, 2007, 2006 and 2005.

The Midwest market’s net income decreased $42 million, or 14 percent, to $277 million in 2007, compared to a decrease of $32 million, or nine percent, to $319 million in 2006. Net interest income (FTE) of $863 million decreased $45 million from 2006, primarily due to a decrease in loan spreads. The provision for loan losses increased $11 million, primarily due to an increase in residential real estate development reserves in 2007, compared to 2006, partially offset by a decrease in reserves related to the automotive industry in 2007. Noninterest income of $471 million increased $19 million from 2006 due to a $10 million increase in fiduciary income, a $6 million increase in card fees and a $3 million increase in brokerage fees. Noninterest expenses of $821 million increased $10 million from 2006, primarily due to a $10 million charge related to the Corporation’s membership in Visa allocated to the Midwest market in 2007, a $5 million increase in salaries and employee benefits expense and a $4 million increase in litigation and operational losses, partially offset by a $5 million decrease in allocated net corporate overhead expenses. Refer to the Business Bank discussion above for an explanation of the decrease in allocated net corporate overhead expenses. The Corporation opened two new banking centers and consolidated five banking centers in Michigan in 2007. In addition, 22 banking centers in Michigan were refurbished in 2007.

The Western market’s net income decreased $103 million, or 38 percent, to $170 million in 2007, compared to a decrease of $65 million, or 19 percent, to $273 million in 2006. Net interest income (FTE) of $706 million increased $5 million, or one percent, in 2007. The increase in net interest income (FTE) was primarily due to a $1.7 billion increase in average loan balances (excluding Financial Services Division) and an $823 million increase in average deposit balances (excluding Financial Services Division), partially offset by a decrease in net interest income from the Financial Services Division and declining loan and deposit spreads. Average low-rate Financial Services Division loan balances declined $1.0 billion in 2007 and average Financial Services Division deposits declined $2.1 billion. The provision for loan losses increased $140 million, primarily due to an increase in credit risk in the California residential real estate development industry in 2007, compared to overall credit improvements in 2006. Noninterest income was $131 million in 2007, a decrease of $29 million from 2006, primarily due to a $47 million Financial Services Division-related lawsuit settlement in 2006, partially offset by a $5 million increase in customer derivative income and a $2 million increase in income from the sale of SBA loans. Noninterest expenses of $455 million increased $5 million, primarily due to a $12 million increase in expenses related to the addition of new banking centers, mostly salaries and employee benefits expense and net occupancy expense. These increases were partially offset by an $8 million decrease in legal fees related to the Financial Services Division-related lawsuit settlement and an $8 million decrease in allocated net corporate overhead expenses. Refer to the Business Bank discussion above for an explanation of the decrease in allocated net corporate overhead expenses. The Corporation opened 16 new banking centers in the Western market in 2007. In addition, two banking centers in the Western market were relocated and two were refurbished in 2007.

The Texas market’s net income decreased $3 million, or three percent, to $79 million in 2007, compared to a decrease of $7 million, to $82 million in 2006. Net interest income (FTE) of $279 million increased $18 million, or seven percent, in 2007, compared to 2006. The increase in net interest income (FTE) was primarily due to an increase in average loan and deposit balances, partially offset by a decrease in loan spreads. The provision for loan losses increased $10 million, primarily due to credit improvements recognized in 2006. Noninterest income of

35

$86 million increased $10 million from 2006, primarily due to a $4 million increase in commercial lending fees and increases in various other fee categories. Noninterest expenses of $235 million increased $19 million from 2006, partially due to a $9 million increase in salaries and employee benefits expense and a $2 million increase in net occupancy expense, primarily related to the addition of new banking centers. These increases were partially offset by a $3 million decrease in allocated net corporate overhead expenses. Refer to the Business Bank discussion above for an explanation of the decrease in allocated net corporate overhead expenses. The Corporation opened 12 new banking centers in the Texas market in 2007, which resulted in a $7 million increase in noninterest expenses. In addition, one banking center in the Texas market was relocated and three were refurbished in 2007.

The Florida market’s net income decreased $7 million, or 46 percent, to $7 million in 2007, compared to a decrease of $1 million, to $14 million in 2006. Net interest income (FTE) of $47 million increased $4 million, or nine percent, from 2006, primarily due to a $164 million increase in average loan balances. The provision for loan losses increased $8 million, primarily due to an increase in residential real estate development industry reserves in 2007, compared to 2006. Noninterest income of $14 million was unchanged from 2006. Noninterest expenses of $39 million increased $5 million from the comparable period in the prior year, partially due to a $2 million increase in salaries and employee benefit expenses.

The Other Markets’ net income increased $17 million to $89 million in 2007, compared to 2006. Net interest income (FTE) of $136 million increased $18 million from 2006, primarily due to a $443 million increase in average loan balances and a $133 million increase in average deposit balances. The provision for loan losses increased $10 million, primarily due to an increase in residential real estate development industry reserves in 2007. Noninterest income of $54 million increased $2 million in 2007 compared to 2006.

The International market’s net income increased $16 million, to $50 million in 2007, compared to 2006. Net interest income (FTE) of $67 million decreased $1 million from the comparable period in the prior year. The provision for loan losses was negative in both 2007 and 2006, due to credit improvements. Noninterest income of $38 million increased $18 million from 2006, primarily due to a $12 million loss on the sale of the Mexican bank charter in the third quarter 2006 and a $4 million increase in net securities gains in 2007. Noninterest expenses of $43 million decreased $7 million in 2007 compared to 2006, reflecting a decrease in salaries and employee benefit expenses and nominal decreases in other expense categories.

Net income for the Finance & Other Business segment was $14 million in 2007, compared to $99 million for 2006. Income from discontinued operations, net of tax, was $4 million in 2007, compared to $111 million for 2006. Discontinued operations in 2006 included a $108 million after-tax gain on the sale of the Corporation’s Munder subsidiary. Net interest income (FTE) increased $21 million, primarily due to the rising rate environment in the first three quarters of the year, during which time interest income received from the lending-related business units increased faster than the longer-term value attributed to deposits generated by the business units, and the maturity of swaps with negative spreads, partially offset by an increase in wholesale funding. Noninterest income increased $13 million, primarily due to a $4 million increase in net income from principal investing and warrants and a $4 million increase in deferred compensation asset returns. The remaining difference is 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.

* Financial Services Division includes primarily low-rate loans

Total loans were $50.7 billion at December 31, 2007, an increase of $3.3 billion from $47.4 billion at December 31, 2006. Total loans, on an average basis, increased $2.0 billion, or four percent, ($3.1 billion, or seven percent, excluding Financial Services Division loans), to $49.8 billion in 2007, from $47.8 billion in 2006. Within average loans, most business lines and geographic markets showed growth. The Corporation continues to make progress toward the goal of achieving more geographic balance, with markets outside of the Midwest comprising 62 percent of average total loans (excluding Financial Services Division loans and loans in the Finance & Other Businesses category) in 2007, compared to 59 percent in 2006.

Average commercial real estate loans, consisting of real estate construction and commercial mortgage loans, increased $1.1 billion, or nine percent, to $14.3 billion in 2007, from $13.2 billion in 2006. Commercial mortgage loans are loans where the primary collateral is a lien on any real property. Real property is generally considered primary collateral if the value of that collateral represents more than 50 percent of the commitment at loan approval. Average loans to borrowers in the Commercial Real Estate business line, which include loans to residential real estate developers, represented $5.2 billion, or 36 percent, of average total commercial real estate loans in 2007, compared to $4.7 billion, or 36 percent, of average total commercial real estate loans in 2006. The increase in average commercial real estate loans to borrowers in the Commercial Real Estate business line in 2007 largely included draws on previously approved lines of credit for residential real estate and commercial

39

development projects and new loans for commercial development projects. The remaining $9.1 billion and $8.5 billion of commercial real estate loans in other business lines in 2007 and 2006, respectively, were primarily owner-occupied commercial mortgages. In addition to the $14.3 billion of average 2007 commercial real estate loans discussed above, the Commercial Real Estate business line also had $1.5 billion of average 2007 loans not classified as commercial real estate on the consolidated balance sheet. Refer to page 52 under Commercial Real Estate Lending in the Risk Management section for more information.

Average residential mortgage loans increased $244 million, or 16 percent, from 2006, and primarily include mortgages originated and retained for certain relationship customers.

Average home equity loans decreased $125 million, or seven percent, from 2006, as a result of a decrease in draws on commitments extended.

Loans classified as Shared National Credit (SNC) loans totaled $10.9 billion (approximately 1,090 borrowers) at December 31, 2007, compared to $8.8 billion (approximately 1,000 borrowers) at December 31, 2006. 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. The Corporation generally seeks to obtain ancillary business at origination of the SNC relationship, or within two years thereafter. These loans, diversified by both line of business and geography, comprised approximately 21 percent and 19 percent of total loans at December 31, 2007 and 2006, respectively.

Management currently expects average loan growth for 2008 to be in the mid to high single-digit range, excluding Financial Services Division loans, with flat growth in the Midwest market, high single-digit growth in the Western market and low double-digit growth in the Texas market, compared to 2007.

Investment securities available-for-sale increased $2.6 billion to $6.3 billion at December 31, 2007, from $3.7 billion at December 31, 2006. Average investment securities available-for-sale increased $455 million to $4.4 billion in 2007, compared to $4.0 billion in 2006, primarily due to a $470 million increase in average U.S. Treasury, Government agency, and Government-sponsored enterprise securities. Changes in U.S. Treasury, Government agency, and Government-sponsored enterprise securities resulted from balance sheet management

40

decisions to reduce interest rate sensitivity. Average other securities decreased $15 million to $131 million in 2007, and consisted largely of money market and other fund investments at December 31, 2007.

Short-term investments include federal funds sold and securities purchased under agreements to resell, and other short-term investments. Federal funds sold offer supplemental earning opportunities and serve correspondent banks. Average federal funds sold and securities purchased under agreements to resell declined $119 million to $164 million during 2007, compared to 2006. Other short-term investments include interest-bearing deposits with banks, trading securities, and loans held-for-sale. Interest-bearing deposits with banks are investments with banks in developed countries or foreign banks’ international banking facilities located in the United States. Loans held-for-sale typically represent residential mortgage loans, student loans and Small Business Administration loans that have been originated and which management has decided to sell. Average other short-term investments decreased $10 million to $256 million during 2007, compared to 2006. Short-term investments, other than loans held-for-sale, provide a range of maturities less than one year and are mostly used to manage short-term investment requirements of the Corporation.

Risk management practices minimize risk inherent in international lending arrangements. These practices include structuring bilateral agreements or participating in bank facilities, which secure repayment from sources external to the borrower’s country. Accordingly, such international outstandings are excluded from the cross-border risk of that country. Mexico, with cross-border outstandings of $915 million, or 1.47 percent of total assets at December 31, 2007, was the only country with outstandings exceeding 1.00 percent of total assets at year-end 2007. There were no countries with cross-border outstandings between 0.75 and 1.00 percent of total assets at year-end 2007. Additional information on the Corporation’s Mexican cross-border risk is provided in Table 7 above.

Total borrowed funds	$	10,277	$	8,061	$	2,216			27	%

Average deposits were $41.9 billion during 2007, a decrease of $140 million, or less than one percent, from 2006. Excluding Financial Services Division, average deposits increased of $1.9 billion, or five percent, from 2006. The $1.7 billion, or six percent, increase in average interest-bearing deposits in 2007, when compared to 2006, resulted primarily from an increase in average customer and institutional certificates of deposit. Institutional certificates of deposit represent certificates of deposit issued to institutional investors in denominations in excess of $100,000 and are an alternative to other sources of purchased funds. The increases in certificates of deposit were partially offset by decreases in average money market, NOW and savings deposits reflecting movement toward higher cost deposits as customers sought higher returns. Average noninterest-bearing deposits decreased $1.8 billion, or 14 percent, from 2006. Noninterest-bearing deposits include title and escrow deposits in the Corporation’s Financial Services Division, which benefit from home mortgage financing and refinancing activity. Financial Services Division deposit levels may change with the direction of mortgage activity changes, and the desirability of and competition for such deposits. Average Financial Services Division noninterest-bearing deposits decreased $1.5 billion, to $2.8 billion in 2007.

Average short-term borrowings decreased $574 million, to $2.1 billion in 2007, compared to $2.7 billion in 2006. Short-term borrowings include federal funds purchased, securities sold under agreements to repurchase and treasury tax and loan notes.

The Corporation uses medium-term debt (both domestic and European) and long-term debt to provide funding to support earning assets while providing liquidity that mirrors the estimated duration of deposits. Long-term subordinated notes further help maintain the Corporation’s and subsidiary banks’ total capital ratios at a level that qualifies for the lowest FDIC risk-based insurance premium. Medium- and long-term debt increased, on an average basis, by $2.8 billion. Further information on medium- and long-term debt is provided in Note 11 to the consolidated financial statements on page 89.

Capital

Common shareholders’ equity was $5.1 billion at December 31, 2007, compared to $5.2 billion at December 31, 2006. The following table presents a summary of changes in common shareholders’ equity in 2007:

	(in millions)

Balance at December 31, 2007			$	5,117

Further information on the change in accumulated other comprehensive income (loss) is provided in Note 13 to the consolidated financial statements on page 92.

The Corporation declared common dividends totaling $393 million, or $2.56 per share, on net income applicable to common stock of $686 million. The dividend payout ratio calculated on a per share basis was 58 percent in 2007 and 43 percent in 2006 and 2005.

The Corporation assesses capital adequacy against the risk inherent in the balance sheet, recognizing that unexpected loss is the common denominator of risk and that common equity has the greatest capacity to absorb unexpected loss. Appropriate capitalization is therefore defined through the use of a target capital range. The Corporation targets to maintain a Tier 1 common capital ratio of between 6.5 percent and 7.5 percent and a Tier 1 capital ratio of between 7.25 percent and 8.25 percent. The Tier 1 common capital ratio is the regulatory Tier 1 capital ratio excluding preferred equity. Based on an interim decision issued by the banking regulators issued in 2006, the after-tax charge associated with a recent accounting standard (SFAS 158) on pension and post-retirement plan accounting was excluded from the calculation of regulatory capital ratios. Therefore, for the purposes of calculating regulatory capital ratios, shareholders’ equity was increased by $170 million and $215 million on December 31, 2007 and 2006, respectively. Refer to Note 19 on page 106 for further discussion of regulatory capital requirements and capital ratio calculations.

When capital exceeds necessary levels, the Corporation’s common stock can be repurchased as a way to return excess capital to shareholders. Repurchasing common stock offers a flexible way to control capital levels by adjusting the capital deployed in reaction to core balance sheet growth. In November 2006 and again in November 2007, the Board of Directors of the Corporation (the Board) authorized the purchase of up to 10 million shares of Comerica Incorporated outstanding common stock in the open market. In addition to limits that result from the Board authorizations, the share repurchase program is constrained by holding company liquidity and capital levels relative to internal targets and regulatory minimums. The Corporation repurchased 10.0 million shares in the open market in 2007 for $580 million, compared to 6.6 million shares in 2006 for $383 million. Comerica Incorporated common stock available for repurchase under Board authority totaled 12.6 million shares at December 31, 2007. Share repurchases combined with dividends returned 142 percent of earnings to shareholders in 2007. Refer to Note 12 to the consolidated financial statements on page 91 for additional information on the Corporation’s share repurchase program.

At December 31, 2007, the Corporation and its U.S. banking subsidiaries exceeded the capital ratios required for an institution to be considered “well capitalized” by the standards developed under the Federal Deposit Insurance Corporation Improvement Act of 1991.

RISK MANAGEMENT

The Corporation assumes various types of risk in the normal course of business. Management classifies the risk exposures into five areas: (1) credit, (2) market and liquidity, (3) operational, (4) compliance and (5) business risks and considers credit risk as the most significant risk. The Corporation employs and is continuously enhancing various risk management processes to identify, measure, monitor and control these risks, as described below.

The Corporation continues to enhance its risk management capabilities with additional processes, tools and systems designed to provide management with deeper insight into the Corporation’s various risks, enhance the Corporation’s ability to control those risks and ensure that appropriate compensation is received for the risks taken.

Specialized risk managers, along with the risk management committees in credit, market and liquidity, and operational and compliance are responsible for the day-to-day management of those respective risks. The Corporation’s Enterprise-Wide Risk Management Committee is responsible for establishing the governance over the risk management process as well as providing oversight in managing the Corporation’s aggregate risk position. The Enterprise-Wide Risk Management Committee is principally made up of the various managers from the different risk areas and business units and has reporting responsibility to the Enterprise Risk Committee of the Board.

Credit Risk

Credit risk represents the risk of loss due to failure of a customer or counterparty to meet its financial obligations in accordance with contractual terms. The Corporation manages credit risk through underwriting, periodically reviewing and approving its credit exposures using Board committee approved credit policies and guidelines. Additionally, the Corporation manages credit risk through loan sales and loan portfolio diversification, limiting exposure to any single industry, customer or guarantor, and selling participationsand/or syndicating to third parties credit exposures above those levels it deems prudent.

During 2007, the Corporation continued its focus on the credit components of the previously described enterprise-wide risk management processes. A two-factor risk rating system was initiated in 2005 and was extended to all portfolios in 2006. Enhancements to the analytics related to capital modeling, migration, credit loss forecasting, stress testing analysis and validation and testing continued in 2007. The evaluation of the Corporation’s loan portfolios with the new tools is anticipated to provide improved measurement of the potential risks within the loan portfolios.

Allowance for Credit Losses

The allowance for credit losses includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments. The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The allowance for loan losses 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 credit quality review quarterly 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 estimated 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 that have experienced above average losses, including portfolio exposures to technology-related industries, Michigan and California residential real estate development and Small Business Administration loans. Furthermore, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios that have not yet manifested themselves in the risk ratings, including portfolio exposures to the automotive industry and California residential real estate development. The portion of the allowance allocated to all other consumer and residential mortgage loans is determined by applying estimated loss ratios to various segments of the loan portfolio. Estimated loss ratios for all portfolios incorporate factors such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and 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 bond tables. 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. Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same estimated loss rates as loans, or with specific reserves. In general, the probability of draw for letters of credit is considered certain once the credit becomes a watch list credit. Non-watch list letters of credits and all unfunded commitments have a lower probability of draw, to which standard loan loss rates are applied.

The total allowance for loan losses was $557 million at December 31, 2007, compared to $493 million at December 31, 2006. The increase resulted mostly from an increase in individual and industry reserves for customers in the real estate industry, primarily Michigan and California residential real estate development. This increase was partially offset by reductions in the industry reserves for customers in the automotive, air transportation, contractor and entertainment industries. An analysis of the changes in the allowance for loan losses is presented in Table 8 on page 45 of this financial review. The allowance for credit losses on lending-related commitments was $21 million at December 31, 2007, compared to $26 million at December 31, 2006, a decrease of $5 million, resulting primarily from a decrease in specific reserves related to unused commitments extended to two large customers in the automotive industry that were previously reserved at quoted prices and now are reserved using standard unfunded commitment methodology. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.

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 that are not necessarily captured by the application of estimated 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 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.

The allowance as a percentage of total loans, nonperforming loans and as a multiple of annual net loan charge-offs is provided in the following table.

	Years Ended December 31
	2007			2006			2005
Allowance for loan losses as a percentage of total loans at end of year		1.10	%		1.04	%		1.19	%

Allowance for loan losses as a multiple of total net loan charge-offs for the year		3.7			8.2			4.7

The allowance for loan losses as a percentage of total period-end loans increased to 1.10 percent at December 31, 2007, from 1.04 percent at December 31, 2006. The allowance for loan losses as a percentage of nonperforming loans decreased to 138 percent at December 31, 2007, from 231 percent at December 31, 2006. The allowance for loan losses as a multiple of net loan charge-offs decreased to 3.7 times for the year ended December 31, 2007, compared to 8.2 times for the prior year, as a result of higher levels of net loan

charge-offs in 2007. While certain ratios declined, the ratios do not reflect a change in the methodology of developing the allowance based on the underlying loan portfolios.

Nonperforming Assets

Nonperforming assets include loans and loans held-for-sale on nonaccrual status, loans which have been renegotiated to less than market rates due to a serious weakening of the borrower’s financial condition, real estate which has been acquired through foreclosure and is awaiting disposition and debt securities on nonaccrual status.

Consumer loans, except for certain large personal purpose consumer and residential mortgage loans, are charged-off no later than 180 days past due, and earlier, if deemed uncollectible. Loans, other than consumer loans, and debt securities are generally placed on nonaccrual status when management determines that principal or interest may not be fully collectible, but no later than 90 days past due on principal or interest, unless the loan or debt security is fully collateralized and in the process of collection. Loan amounts in excess of probable future cash collections are charged-off to an amount that management ultimately expects to collect. Interest previously accrued but not collected on nonaccrual loans is charged against current income at the time the loan is placed on nonaccrual. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Loans that have been restructured to yield a rate that was equal to or greater

48

than the rate charged for new loans with comparable risk and have met the requirements for a return to accrual status are not included in nonperforming assets. However, such loans may be required to be evaluated for impairment. Refer to Note 4 of the consolidated financial statements on page 83 for a further discussion of impaired loans.

Nonperforming assets increased $191 million, or 82 percent, to $423 million at December 31, 2007, from $232 million at December 31, 2006. Table 10 above shows changes in individual categories. The $177 million increase in nonaccrual loans at December 31, 2007 from year-end 2006 levels resulted primarily from a $147 million increase in nonaccrual real estate construction loans and a $69 million increase in nonaccrual commercial mortgage loans, partially offset by a $22 million decrease in nonaccrual commercial loans, an $8 million decrease in nonaccrual international loans and an $8 million decrease in nonaccrual lease financing loans. An analysis of nonaccrual loans at December 31, 2007, based primarily on the Standard Industrial Classification (SIC) code, is presented on page 51 of this financial review. Loans past due 90 days or more and still on accrual status increased $40 million, to $54 million at December 31, 2007, from $14 million at December 31, 2006. Nonperforming assets as a percentage of total loans, foreclosed property and nonaccrual debt securities was 0.83 percent and 0.49 percent at December 31, 2007 and 2006, respectively.

The following table presents a summary of changes in nonaccrual loans.

There were 58 loan relationships with balances greater than $2 million, totaling $455 million that were transferred to nonaccrual status in 2007, an increase of $279 million, when compared to $176 million in 2006. Of the transfers to nonaccrual with balances greater than $2 million in 2007, $286 million were from the Midwest market and $132 million were from the Western market. There were 11 loan relationships greater than $10 million transferred to nonaccrual in 2007. The 11 loan relationships totaled $236 million and were to companies in the real estate ($188 million) and retail trade ($48 million) industries.

The Corporation sold $15 million of nonaccrual business loans in 2007. These loans were to customers in the real estate, automotive production and airline transportation industries. In addition, the Corporation sold $82 million of unused commitments in 2007, including $60 million with customers in the automotive industry. The losses associated with the sale of the unused commitments were charged to the “provision for credit losses on lending-related commitments” on the consolidated statements of income.

Nonaccrual loan payments/other, as shown in the table above, increased $48 million in 2007, when compared to 2006. The increase was mostly due to an increase in payments received on nonaccrual loans greater than $2 million in 2007, compared to 2006.

The following table presents a summary of total internally classified watch list loans (generally consistent with regulatory defined special mention, substandard and doubtful loans) at December 31, 2007. Of the $3.5 billion of watch list loans, $1.1 billion, or 31 percent were in the Commercial Real Estate business line. Consistent with the increase in nonaccrual loans from December 31, 2006 to December 31, 2007, total watch list loans increased both in dollars and as a percentage of the total loan portfolio.

(2)	Consumer nonaccrual loans and net charge-offs are included in the “Other” category.

SNC nonaccrual loans comprised six percent and less than one percent of total nonaccrual loans at December 31, 2007 and 2006, respectively. As a percentage of total loans, SNC loans represented approximately 21 percent and 19 percent at December 31, 2007 and 2006, respectively. SNC loan net charge-offs were $2 million in both 2007 and 2006. For further discussion of the Corporation’s SNC relationships, refer to the “Earning Assets” section of this financial review on page 38.

Concentration of Credit

Loans to borrowers in the automotive industry represented the largest significant industry concentration at December 31, 2007 and 2006. Loans to automotive dealers and to borrowers involved with automotive production are reported as automotive, since management believes these loans have similar economic characteristics that might cause them to react similarly to changes in economic conditions. This aggregation involves the exercise of judgment. Included in automotive production are: (a) original equipment manufacturers and Tier 1 and Tier 2 suppliers that produce components used in vehicles and whose primary revenue source is automotive-related (“primary” defined as greater than 50%) and (b) other manufacturers that produce components used in vehicles and whose primary revenue source is automotive-related. Loans less than $1 million and loans recorded in the Small Business division were excluded from the definition. Foreign ownership consists of North American affiliates of foreign automakers and suppliers.

At December 31, 2007, dealer loans, as shown in the table above, totaled $5.4 billion, of which approximately $3.1 billion, or 59 percent, was to foreign franchises, $1.7 billion, or 31 percent, was to domestic franchises and $561 million, or 10 percent, was to other. Other includes 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.

Nonaccrual loans to automotive borrowers comprised approximately four percent of total nonaccrual loans at December 31, 2007. The largest automotive loan on nonaccrual status at December 31, 2007 was $5 million. Total automotive net loan recoveries were $2 million in 2007. The following table presents a summary of automotive net loan and credit-related charge-offs for the years ended December 31, 2007 and 2006.

All other industry concentrations, as defined by management, individually represented less than 10 percent of total loans at year-end 2007.

Commercial Real Estate Lending

The Corporation takes measures to limit risk inherent in its commercial real estate lending activities. These measures include limiting exposure to those borrowers directly involved in the commercial real estate markets and adherence to policies requiring conservative loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $14.9 billion at December 31, 2007, of which $5.5 billion, or 37 percent, were to borrowers in the Commercial Real Estate business line. Increased

52

nonaccrual loans, reserves and net charge-offs in the Commercial Real Estate business line reflected challenges in the residential real estate development industry in Michigan and California.

The real estate construction loan portfolio contains loans primarily made to long-time customers with satisfactory completion experience. The portfolio totaled $4.8 billion and included approximately 1,650 loans, of which 48 percent had balances less than $1 million at December 31, 2007. The largest real estate construction loan had a balance of approximately $43 million at December 31, 2007. The commercial mortgage loan portfolio totaled $10.1 billion at December 31, 2007 and included approximately 8,900 loans, of which 74 percent had balances of less than $1 million. This total included $8.7 billion of primarily owner-occupied commercial mortgage loans. The largest loan within the commercial mortgage loan portfolio had a balance of approximately $56 million at December 31, 2007.

The geographic distribution of commercial real estate loan borrowers is an important factor in diversifying credit risk. The following table indicates, by location of property and by project type, the diversification of the Corporation’s real estate construction and commercial mortgage loans to borrowers in the Commercial Real Estate business line.

Of the $4.1 billion of real estate construction loans in the Commercial Real Estate business line, $161 million were on nonaccrual status at December 31, 2007. Substantially all of the nonaccrual loans were Single Family, Land Development and Land Carry project types located in California ($84 million), Michigan ($57 million) and Florida ($18 million).

Commercial mortgage loans in the Commercial Real Estate business line totaled $1.4 billion and included $66 million of nonaccrual loans at December 31, 2007, primarily Land Development projects located in Michigan ($55 million).

53

Net charge-offs in the Commercial Real Estate business line were $52 million in 2007, and included $34 million in the Midwest market, $16 million in the Western market and $2 million in the Texas market.

Market Risk

Market risk represents the risk of loss due to adverse movements in market rates or prices, which include interest rates, foreign exchange rates and equity prices; the failure to meet financial obligations coming due because of an inability to liquidate assets or obtain adequate funding and the inability to easily unwind or offset specific exposures without significantly lowering prices because of inadequate market depth or market disruptions.

The Asset and Liability Policy Committee (ALPC) establishes and monitors compliance with the policies and risk limits pertaining to market risk management activities. The ALPC meets regularly to discuss and review market risk management strategies and is comprised of executive and senior management from various areas of the Corporation, including finance, lending, deposit gathering and risk management.

Interest Rate Risk

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 in our core businesses will lead to a greater sensitivity to interest rate movements, without mitigating actions. An example of such an action is purchasing investment securities, primarily fixed rate, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity. The Corporation actively manages its exposure to interest rate risk, with the principal objective of optimizing net interest income while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.

Interest Rate Sensitivity

Interest rate risk arises in the normal course of business due to differences in the repricing and cash flow characteristics of assets and liabilities. Since no single measurement system satisfies all management objectives, a combination of techniques is used to manage interest rate risk. These techniques examine earnings at risk and economic value of equity utilizing multiple simulation analyses.

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 an unchanged interest rate environment and what is believed to be the most likely balance sheet structure. This “base” net interest income is then evaluated against non-parallel interest rate scenarios that increase and decrease approximately 200 basis points (but no lower than zero percent)

54

from the unchanged interest rate environment. For this analysis, the rise or decline in interest rates occurs in a linear fashion over twelve 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 December 31, 2007 and 2006 displays the estimated impact on net interest income during the next 12 months as it relates the unchanged interest rate scenario results to those from the 200 basis point non-parallel shock described above.

Sensitivity of Net Interest Income to Changes in Interest Rates

	December 31
	2007						2006
	Amount			%			Amount			%
	(in millions)
Change in Interest Rates:
+200 basis points	$	38			2	%	$	34			2	%
−200 basis points		(36	)		(2	)		(51	)		(2	)

Corporate policy limits adverse change to no more than four percent of management’s most likely net interest income forecast and the Corporation operated within this policy guideline. The change in interest rate sensitivity from December 31, 2006 to December 31, 2007 was primarily a result of loan and deposit growth, activities in the Financial Services Division, competitive deposit pricing, maturity of swaps and additions to the investment securities portfolio. In addition, a variety of alternative scenarios are performed to assist in the portrayal of the Corporation’s interest rate risk position, including, but not limited to, flat balance sheet and most likely rates, 200 basis point parallel rate shocks and yield curve twists. Interest rate risk will be actively managed principally through the use of on-balance sheet financial instruments or interest rate swaps so that the desired risk profile is achieved.

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 upon the market value of assets, liabilities and off-balance sheet instruments. The economic value of equity is then calculated as the difference between the market value of assets and liabilities net of the impact of off-balance sheet instruments. 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 operated 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 changes in the level, slope and shape of the yield curve.

Sensitivity of Economic Value of Equity to Changes in Interest Rates

−200 basis points		(789	)		(9	)		(351	)		(4	)

The change in economic value of equity sensitivity from December 31, 2006 to December 31, 2007 was primarily due to the issuance of $515 million of 6.576% fixed rate subordinate notes due 2037, which accounted for the majority of the decline under the 200 basis point parallel decrease in the interest rates scenario in the table above. Other contributing factors were changes in loan and funding mix, and a runoff in interest rate swaps partly offset by additions to the investment securities portfolio.

55

The Corporation uses investment securities and derivative instruments, predominantly interest rate swaps, as asset and liability management tools with the overall objective of managing the volatility of net interest income from changes in interest rates. Swaps modify the interest rate characteristics of certain assets and of liabilities (e.g., from a floating rate to a fixed rate, from a fixed rate to a floating rate or from one floating rate index to another). These tools assist management in achieving the desired interest rate risk management objectives.

The notional amount of risk management interest rate swaps totaled $5.4 billion at December 31, 2007, and $8.5 billion at December 31, 2006. The decrease in notional amount of $3.1 billion from December 31, 2006 to December 31, 2007 reflects maturities and a current preference for on-balance sheet risk management utilizing the investment securities portfolio. The fair value of risk management interest rate swaps was a net unrealized gain of $143 million at December 31, 2007, compared to a net unrealized loss of $19 million at December 31, 2006.

For the year ended December 31, 2007, risk management interest rate swaps generated $55 million of net interest expense, compared to $108 million of net expense for the year ended December 31, 2006. The decrease in swap expense for 2007, compared to 2006, was primarily due to the maturities of interest rate swaps that carried a negative spread.

Table 11 on page 57 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 as of December 31, 2007. Swaps have been grouped by asset and liability designation.

In addition to interest rate swaps, the Corporation employs various other types of derivative instruments to mitigate exposures to interest rate and foreign currency risks associated with specific assets and liabilities (e.g., loans or deposits denominated in foreign currencies). Such instruments may include interest rate caps and floors, purchased put options, foreign exchange forward contracts and foreign exchange swap agreements. The aggregate notional amounts of these risk management derivative instruments at December 31, 2007 and 2006 were $549 million and $551 million, respectively.

Further information regarding risk management derivative instruments is provided in Notes 1, 11, and 20 to the consolidated financial statements on pages 72, 89 and 107, respectively.

The Corporation writes and purchases interest rate caps and enters into foreign exchange contracts, interest rate swaps and energy derivative contracts to accommodate the needs of customers requesting such services. Customer-initiated and other notional activity represented 68 percent of total interest rate, energy and foreign exchange contracts at December 31, 2007, compared to 52 percent at December 31, 2006. Refer to Notes 1 and 20 of the consolidated financial statements on pages 72 and 107, respectively, for further information regarding customer-initiated and other derivative instruments.

57

Warrants

The Corporation holds a portfolio of approximately 840 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 on page 72, 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 (approximately 570 warrants at December 31, 2007). The value of all warrants that are carried at fair value ($23 million at December 31, 2007) is at risk to changes in equity markets, general economic conditions and other factors. For further information regarding the valuation of warrants accounted for as derivatives, refer to the “Critical Accounting Policies” section of this financial review on page 62.

Liquidity Risk and Off-Balance Sheet Arrangements

Liquidity is the ability to meet financial obligations through the maturity or sale of existing assets or the acquisition of additional funds. The Corporation has various financial obligations, including contractual obligations and commercial commitments, which may require future cash payments. The following contractual obligations table summarizes the Corporation’s noncancelable contractual obligations and future required minimum payments, and includes unrecognized tax benefits in “other long-term obligations”. Refer to Notes 7, 10, 11 and 17 of the financial statements on pages 86, 88, 89 and 103, respectively, for a further discussion of these contractual obligations.

The Corporation has other commercial commitments that impact liquidity. These commitments include commitments to purchase and sell earning assets, commitments to fund private equity and venture capital investments, unused commitments to extend credit, standby letters of credit and financial guarantees, and commercial letters of credit. The following commercial commitments table summarizes the Corporation’s commercial commitments and expected expiration dates by period.

Since many of these commitments expire without being drawn upon, the total amount of these commercial commitments does not necessarily represent the future cash requirements of the Corporation. Refer to the “Other Market Risks” section below and Note 20 of the consolidated financial statements on page 107 for a further discussion of these commercial commitments.

Liquidity requirements are satisfied with various funding sources. First, the Corporation accesses the purchased funds market regularly to meet funding needs. Purchased funds, comprised of customer certificates of deposit of $100,000 and over that mature in less than one year, institutional certificates of deposit, foreign office time deposits and short-term borrowings, approximated $13.0 billion at December 31, 2007, compared to $9.3 billion and $3.5 billion at December 31, 2006 and 2005, respectively. Second, a $15 billion medium-term senior note program allows the principal banking subsidiary to issue debt with maturities between one and 30 years. At year-end 2007, unissued debt relating to the medium-term note program totaled $9.6 billion. A third source, if needed, would be liquid assets, including cash and due from banks, federal funds sold and securities purchased under agreements to resell, other short-term investments and investment securities available-for-sale, which totaled $8.1 billion at December 31, 2007. Additionally, the Corporation also had available $16 billion from a collateralized borrowing account with the Federal Reserve Bank at December 31, 2007.

In February 2008, Comerica Bank (the Bank), a subsidiary of the Corporation, became a member of the Federal Home Loan Bank of Dallas, Texas (FHLB), which provides short- and long-term funding to its members though advances that are collateralized by mortgage-related assets. The initial required investment by the Bank in FHLB stock was $25 million. Additional investment in FHLB stock would be required in relation to the level of outstanding borrowings. The actual borrowing capacity is contingent on the amount of collateral available to be pledged to FHLB. As of December 31, 2007, the Corporation had no borrowings from FHLB.

The parent company held $1 million of cash and cash equivalents and $224 million of short-term investments with a subsidiary bank at December 31, 2007. Another source of liquidity for the parent company is dividends from its subsidiaries. As discussed in Note 19 to the consolidated financial statements on page 106, banking subsidiaries are subject to regulation and may be limited in their ability to pay dividends or transfer funds to the holding company. During 2008, the banking subsidiaries can pay dividends up to $234 million plus 2008 net profits without prior regulatory approval. One measure of current parent company liquidity is investment in subsidiaries as a percentage of shareholders’ equity. An amount over 100 percent represents the reliance on subsidiary dividends to repay liabilities. As of December 31, 2007, the ratio was 114 percent. The Contractual Obligations table on page 58 includes information on parent company future minimum payments on medium- and long-term debt.

The Corporation regularly evaluates its ability to meet funding needs in unanticipated, stress environments. In conjunction with the quarterly 200 basis point interest rate shock analyses, discussed in the “Interest Rate Sensitivity” section on page 54 of this financial review, liquidity ratios and potential funding availability are examined. Each quarter, the Corporation also evaluates its ability to meet liquidity needs under a series of broad events, distinguished in terms of duration and severity. The evaluation projects that sufficient sources of liquidity are available in each series of events.

59

The Corporation also holds a significant interest in certain variable interest entities (VIE’s), in which it is not the primary beneficiary and does not consolidate. These unconsolidated VIE’s are principally private equity and venture capital funds, or low income housing limited partnerships. The Corporation defines a significant interest in a VIE as a subordinated interest that exposes it to a significant portion of the VIE’s expected losses or residual returns. In general, a VIE is an entity that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. If any of these characteristics is present, the entity is subject to a variable interests consolidation model, and consolidation is based on variable interests, not on ownership of the entity’s outstanding voting stock. Variable interests are defined as contractual, ownership, or other monetary interests in an entity that change with fluctuations in the entity’s net asset value. A company must consolidate an entity depending on whether the entity is a voting rights entity or a VIE. Refer to the “principles of consolidation” section in Note 1 of the consolidated financial statements on page 72 for a summarization of the Corporation’s consolidation policy. Also refer to Note 22 of the consolidated financial statements on page 114 for a discussion of the Corporation’s involvement in VIE’s, including those in which it holds a significant interest but for which it is not the primary beneficiary.

Other Market Risks

The Corporation’s market risk related to trading instruments is not significant, as trading activities are limited. Certain components of the Corporation’s noninterest income, primarily fiduciary income, are at risk to fluctuations in the market values of underlying assets, particularly equity securities. Other components of noninterest income, primarily brokerage fees, are at risk to changes in the level of market activity.

Share-based compensation expense recognized by the Corporation is dependent upon the fair value of stock options and restricted stock at the date of grant. The fair value of both stock options and restricted stock is impacted by the market price of the Corporation’s stock on the date of grant and is at risk to changes in equity markets, general economic conditions and other factors. For further information regarding the valuation of stock options and restricted stock, refer to the “Critical Accounting Policies” section of this financial review on page 62.

Indirect Private Equity and Venture Capital Investments

At December 31, 2007, the Corporation had a $74 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. For further information regarding the valuation of indirect private equity and venture capital investments, refer to the “Critical Accounting Policies” section of this financial review on page 62. Approximately $12 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. Income from unconsolidated indirect private equity and venture capital investments in 2007 was $27 million, which was partially offset by $11 million of write-downs recognized on such investments in 2007. No generic assumption is applied to all investments when evaluating for impairment. The uncertainty in the economy and equity markets may affect the values of the fund investments. The following table provides information on the Corporation’s indirect private equity and venture capital investments portfolio.

Operational Risk

Operational risk represents the risk of loss resulting from inadequate or failed internal processes, people and systems, or from external events. The definition includes legal risk, which is the risk of loss resulting from failure to comply with laws and regulations as well as prudent ethical standards and contractual obligations. It also includes the exposure to litigation from all aspects of an institution’s activities. The definition does not include strategic or reputational risks. Although operational losses are experienced by all companies and are routinely incurred in business operations, the Corporation recognizes the need to identify and control operational losses, and seeks to limit losses to a level deemed appropriate by management after considering the nature of the Corporation’s business and the environment in which it operates. Operational risk is mitigated through a system of internal controls that are designed to keep operating risks at appropriate levels. An Operational Risk Management Committee ensures appropriate risk management techniques and systems are maintained. The Corporation has developed a framework that includes a centralized operational risk management function and business/support unit risk coordinators responsible for managing operational risk specific to the respective business lines.

In addition, internal audit and financial staff monitors and assesses the overall effectiveness of the system of internal controls on an ongoing basis. Internal Audit reports the results of reviews on the controls and systems to management and the Audit Committee of the Board. The internal audit staff independently supports the Audit Committee oversight process. The Audit Committee serves as an independent extension of the Board.

Compliance Risk

Compliance risk represents the risk of regulatory sanctions, reputational impact or financial loss resulting from its failure to comply with regulations and standards of good banking practice. Activities which may expose the Corporation to compliance risk include, but are not limited to, those dealing with the prevention of money laundering, privacy and data protection, community reinvestment initiatives, fair lending challenges resulting from the Corporation’s expansion of its banking center network and employment and tax matters.

The Enterprise-Wide Compliance Committee, comprised of senior business unit managers as well as managers responsible for compliance, audit and overall risk, oversees compliance risk. This enterprise-wide approach provides a consistent view of compliance across the organization. The Enterprise-Wide Compliance Committee also ensures that appropriate actions are implemented in business units to mitigate risk to an acceptable level.

Business Risk

Business risk represents the risk of loss due to impairment of reputation, failure to fully develop and execute business plans, failure to assess current and new opportunities in business, markets and products, and any other event not identified in the defined risk categories of credit, market and liquidity, operational or compliance risks. Mitigation of the various risk elements that represent business risk is achieved through initiatives to help the Corporation better understand and report on the various risks. Wherever quantifiable, the Corporation intends to use situational analysis and other testing techniques to appreciate the scope and extent of these risks.

61

CRITICAL ACCOUNTING POLICIES

The consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described on page 72 in Note 1 to the 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. The most critical of these significant accounting policies are the policies for allowance for credit losses, pension plan accounting, income taxes and the valuation of restricted stock and stock options, nonmarketable equity securities and warrants. These policies are reviewed with the Audit Committee of the Board and are discussed more fully below.

Allowance for Credit Losses

The allowance for credit losses (combined allowance for loan losses and allowance for credit losses on lending-related commitments) is calculated with the objective of maintaining a reserve sufficient to absorb estimated probable losses. Management’s determination of the adequacy of the allowance is based on periodic evaluations of the loan portfolio, lending-related commitments, and other relevant factors. However, this evaluation is inherently subjective as it requires an estimate of the loss content for each risk rating and for each impaired loan, an estimate of the amounts and timing of expected future cash flows, an estimate of the value of collateral, including the market value of thinly traded or nonmarketable equity securities, and an estimate of the probability of drawing on unused commitments.

Allowance for Loan Losses

Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Consistent with this definition, all nonaccrual and reduced-rate loans (with the exception of residential mortgage and consumer loans) are impaired. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. The valuation is reviewed and updated on a quarterly basis. While the determination of fair value may involve estimates, each estimate is unique to the individual loan, and none is individually significant.

The portion of the allowance allocated to the remaining loans is determined by applying estimated loss ratios to loans in each risk category. Estimated loss ratios incorporate factors such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and are supported by underlying analysis, including information on migration and loss given default studies from each of the three major domestic geographic markets, as well as mapping to bond tables. Since a loss ratio is applied to a large portfolio of loans, any variation between actual and assumed results could be significant. In addition, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios that have experienced above average losses, including portfolio exposures to technology-related industries, Michigan and California residential real estate development and Small Business Administration loans. Furthermore, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios that have not yet manifested themselves in the risk rating, including portfolio exposures to the automotive industry and California residential real estate development.

A portion of the allowance is also maintained to cover factors affecting the determination of probable losses inherent in the loan portfolio that are not necessarily captured by the application of estimated loss ratios or identified industry specific risks. These factors include the imprecision in the risk rating system and the risk associated with new customer relationships.

The principle assumption used in deriving the allowance for loan losses is the estimate of loss content for each risk rating. To illustrate, if recent loss experience dictated that the estimated loss ratios would be changed by five percent (of the estimate) across all risk ratings, the allocated allowance as of December 31, 2007 would change by approximately $14 million.

62

Allowance for Credit Losses on Lending-Related Commitments

Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same estimated loss rates as loans, or with specific reserves. In general, the probability of draw for letters of credit is considered certain once the credit becomes a watch list credit. Non-watch list letters of credits and all unfunded commitments have a lower probability of draw, to which standard loan loss rates are applied.

Automotive Industry Concentration

A concentration in loans to the automotive industry could result in significant changes to the allowance for credit losses if assumptions underlying the expected losses differed from actual results. For example, a bankruptcy by a domestic automotive manufacturer could adversely affect the risk ratings of its suppliers, causing actual losses to differ from those expected. The allowance for loan losses included a component for automotive suppliers, which assumed that suppliers who derive a significant portion of their revenue from certain domestic manufacturers would be downgraded by one or two risk ratings in the event of bankruptcy of those domestic manufacturers.

For further discussion of the methodology used in the determination of the allowance for credit losses, refer to the “Allowance for Credit Losses” section in this financial review on page 46, and Note 1 to the consolidated financial statements on page 72. To the extent actual outcomes differ from management estimates, additional provision for credit losses may be required that would adversely impact earnings in future periods. A substantial majority of the allowance is assigned to business segments. Any earnings impact resulting from actual outcomes differing from management estimates would primarily affect the Business Bank segment.

Pension Plan Accounting

The Corporation has defined benefit plans in effect for substantially all full-time employees hired before January 1, 2007. Benefits under the plans are based on years of service, age and compensation. Assumptions are made concerning future events that will determine the amount and timing of required benefit payments, funding requirements and pension expense (income). The three major assumptions are the discount rate used in determining the current benefit obligation, the long-term rate of return expected on plan assets and the rate of compensation increase. The assumed discount rate is determined by matching the expected cash flows of the pension plans to a yield curve that is representative of long-term, high-quality fixed income debt instruments as of the measurement date, December 31. The second assumption, long-term rate of return expected on plan assets, is set after considering both long-term returns in the general market and long-term returns experienced by the assets in the plan. The current asset allocation and target asset allocation model for the plans is detailed in Note 16 on page 97. The expected returns on these various asset categories are blended to derive one long-term return assumption. The assets are invested in certain collective investment funds and mutual investment funds, equity securities, U.S. Treasury and other Government agency securities, Government-sponsored enterprise securities and corporate bonds and notes. The third assumption, rate of compensation increase, is based on reviewing recent annual pension-eligible compensation increases as well as the expectation of future increases. The Corporation reviews its pension plan assumptions on an annual basis with its actuarial consultants to determine if the assumptions are reasonable and adjusts the assumptions to reflect changes in future expectations.

The key actuarial assumptions that will be used to calculate 2008 expense for the defined benefit pension plans are a discount rate of 6.47 percent, a long-term rate of return on assets of 8.25 percent, and a rate of compensation increase of 4.00 percent. Pension expense in 2008 is expected to be approximately $21 million, a decrease of $15 million from the $36 million recorded in 2007, primarily due to changes in the discount rate.

Changing the 2008 key actuarial assumptions discussed above in 25 basis point increments would have the following impact on pension expense in 2008:

	25 Basis Point
Key Actuarial Assumption	Increase			Decrease
	(in millions)
Discount rate	$	(6.1	)	$	6.1
Long-term rate of return		(3.0	)		3.0
Rate of compensation		3.0			(3.0	)

63

If the assumed long-term return on assets differs from the actual return on assets, the asset gains and losses are incorporated in the market-related value, which is used to determine the expected return on assets, over a five-year period. The Employee Benefits Committee, which is comprised of executive and senior managers from various areas of the Corporation, provides broad asset allocation guidelines to the asset manager, who reports results and investment strategy quarterly to the Committee. Actual asset allocations are compared to target allocations by asset category and investment returns for each class of investment are compared to expected results based on broad market indices.

Note 16 on page 97 to the consolidated financial statements contains a table showing the funded status of the qualified defined benefit plan at year-end which was $200 million at December 31, 2007. Due to the long-term nature of pension plan assumptions, actual results may differ significantly from the actuarial-based estimates. Differences between estimates and experience not recovered in the market or by future assumption changes are required to be recorded in shareholders’ equity as part of accumulated other comprehensive income (loss) and amortized to pension expense in future years. For further information, refer to Note 1 to the consolidated financial statements on page 72. The actuarial net loss in the qualified defined benefit plan recognized in accumulated other comprehensive income (loss) at December 31, 2007 was $48 million, net of tax. In 2007, the actual return on plan assets was $89 million, compared to an expected return on plan assets of $93 million. In 2006, the actual return on plan assets was $123 million, compared to an expected return on plan assets of $89 million. The Corporation may make contributions from time to time to the qualified defined benefit plan to mitigate the impact of the actuarial losses on future years. No contributions were made to the plan in 2007. For the foreseeable future, the Corporation has sufficient liquidity to make such payments.

Pension expense is recorded in “employee benefits” expense on the consolidated statements of income, and is allocated to business segments based on the segment’s share of salaries expense. Given the salaries expense included in 2007 segment results, pension expense was allocated approximately 38 percent, 34 percent, 23 percent and 5 percent to the Retail Bank, Business Bank, Wealth & Institutional Management and Finance segments, respectively, in 2007.

Income Taxes

The calculation of the Corporation’s income tax provision and related tax accruals is complex and requires the use of estimates and judgments. The provision for income taxes is based on amounts reported in the consolidated statements of income (after deducting non-taxable items, principally income on bank-owned life insurance and deducting tax credits related to investments in low income housing partnerships) and includes deferred income taxes on temporary differences between the tax basis and financial reporting basis of assets and liabilities. Accrued taxes represent the net estimated amount due or to be received from taxing jurisdictions currently or in the future and are included in “accrued income and other assets” or “accrued expenses and other liabilities” on the consolidated balance sheets. The Corporation assesses the relative risks and merits of tax positions for various transactions after considering statutes, regulations, judicial precedent and other available information, and maintains tax accruals consistent with these assessments. The Corporation is subject to audit by taxing authorities that could questionand/or challenge the tax positions taken by the Corporation. In the event of such a challenge, the Corporation would pursue any disallowed taxes through administrative measures, and if necessary, vigorously defend its position in court in accordance with its view of the law.

Included in net deferred taxes are deferred tax assets. Deferred tax assets are evaluated for realization based on available evidence and assumptions made regarding future events. In the event that the future taxable income does not occur in the manner anticipated, other initiatives could be undertaken to preclude the need to recognize a valuation allowance against the deferred tax asset. A valuation allowance is provided when it is more-likely-than-not that some portion of the deferred tax asset will not be realized. At December 31, 2007, a valuation allowance of approximately $2 million was established for certain state deferred tax assets.

Changes in the estimate of accrued taxes occur due to changes in tax law, interpretations of existing tax laws, new judicial or regulatory guidance, and the status of examinations conducted by taxing authorities that impact the relative risks and merits of tax positions taken by the Corporation. These changes in the estimate of accrued taxes could be significant to the operating results of the Corporation. For further information on tax accruals and related risks, see Note 17 to the consolidated financial statements on page 103.

On January 1, 2007, the Corporation adopted the provisions of FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109,” (FIN 48). FIN 48 provides guidance on measurement, de-recognition of tax benefits, classification, accounting disclosure and transition requirements in accounting for uncertain tax positions. For further discussion of FIN 48, refer to Note 17 to the consolidated financial statements on page 103.

Valuation Methodologies

Restricted Stock and Stock Options

The fair value of share-based compensation as of the date of grant is recognized as compensation expense on a straight-line basis over the vesting period. In 2007, the Corporation recognized total share-based compensation expense of $59 million. The Corporation used a binomial model to value stock options granted subsequent to March 31, 2005. Substantially all stock options granted in 2005 and thereafter were valued using a binomial model. The option valuation model requires several inputs, including the risk-free interest rate, the expected dividend yield, expected volatility factors of the market price of the Corporation’s common stock and the expected option life. For further discussion on the valuation model inputs, see Note 15 to the consolidated financial statements on page 95. Changes in input assumptions can materially affect the fair value estimates. The option valuation model is sensitive to the market price of the Corporation’s stock at the grant date, which affects the fair value estimates and, therefore, the amount of expense recorded on future grants. Using the number of stock options granted in 2007 and the Corporation’s stock price at December 31, 2007, a $5.00 per share increase in stock price would result in an increase in pretax expense of approximately $3 million, from the assumed base, over the options’ vesting period. The fair value of restricted stock is based on the market price of the Corporation’s stock at the grant date. Using the number of restricted stock awards issued in 2007, a $5.00 per share increase in stock price would result in an increase in pretax expense of approximately $2 million, from the assumed base, over the awards’ vesting period. Refer to Notes 1 and 15 of the consolidated financial statements on pages 72 and 95, respectively, for further discussion of share-based compensation expense.

Nonmarketable Equity Securities

At December 31, 2007, the Corporation had a $74 million portfolio of indirect (through funds) private equity and venture capital investments, and had commitments to fund additional investments of $42 million in future periods. The majority of these investments are not readily marketable. The investments are individually reviewed for impairment, on a quarterly basis, by comparing the carrying value to the estimated fair value. The Corporation bases its estimates of fair value for the majority of its indirect private equity and venture capital investments on the percentage ownership in the fair value of the entire fund, as reported by the fund management. In general, the Corporation does not have the benefit of the same information regarding the fund’s underlying investments as does fund management. Therefore, after indication that fund management adheres to accepted, sound and recognized valuation techniques, the Corporation generally utilizes the fair values assigned to the underlying portfolio investments by fund management. The impact on fair values of future capital calls and transfer restrictions is not considered by fund management, and the Corporation assumes it to be insignificant. For those funds where fair value is not reported by fund management, 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 fund management, 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 amount by which the carrying value exceeds the fair value that is determined to be other-than-temporary impairment, is charged to current earnings and the carrying value of the investment is written down accordingly. While the determination of fair value involves estimates, no generic assumption is applied to all investments when evaluating for impairment. As such, each estimate is unique to the individual investment, and none is individually significant. The inherent uncertainty in the process of valuing equity securities for which a ready market is unavailable may cause our estimated values of these securities to differ significantly from the values that would have been derived had a ready market for the securities existed, and those differences could be material. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other

65

factors, which could result in an impairment charge in future periods. The valuation of nonmarketable equity securities may be impacted by the adoption of SFAS No. 157, “Fair Value Measurement,” (SFAS 157). For further discussion of SFAS 157, refer to Note 2 to the consolidated financial statements on page 79.

Warrants

The Corporation holds a portfolio of approximately 840 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. Warrants which contain a net exercise provision (approximately 570 warrants at December 31, 2007), are required to be accounted for as derivatives and recorded at fair value ($23 million at December 31, 2007) in accordance with the provisions of Implementation Issue 17a of SFAS 133, “Accounting for Derivative Instruments and Hedging Activities.” The fair value of the derivative warrant portfolio is reviewed quarterly and adjustments to the fair value are recorded quarterly in current earnings. Fair value is determined using a Black-Scholes valuation model, which has five inputs: risk-free rate, expected life, volatility, exercise price, and the per share market value of the underlying company. Key assumptions used in the December 31, 2007 valuation were as follows. The risk-free rate was estimated using the U.S. treasury rate, as of the valuation date, corresponding with the expected life of the warrant. The Corporation used an expected term of one half of the remaining contractual term of each warrant. Volatility was estimated using an index of comparable publicly traded companies, based on the Standard Industrial Classification codes. Where sufficient financial data exists, a market approach method was utilized to estimate the current value of the underlying company. When quoted market values were not available, an index method was utilized. Under the index method, the subject companies’ values were “rolled-forward” from the inception date through the valuation date based on the change in value of an underlying index of guideline public companies. The liquidity of each warrant, or the portfolio of warrants, is not considered in Black-Scholes, and the Corporation historically assumed this nonmarketability to be insignificant.

The fair value of warrants recorded on the Corporation’s consolidated balance sheets represents management’s best estimate of the fair value of these instruments within the framework of existing accounting standards. Changes in the above material assumptions could result in significantly different valuations. For example, the following table demonstrates the effect of changes in the volatility assumption used, currently 60 percent, on the value of warrants required to be carried at fair value:

Valuation of Warrants Held at December 31, 2007

	Change in Volatility Factor
	20% Lower			20% Higher
	(dollar amounts in millions)
Value of all warrants required to be carried at fair value	$	(1.5	)	$	1.7

Based on expected average life of 1.7 years

The valuation of warrants is complex and is subject to a certain degree of management judgment. The inherent uncertainty in the process of valuing warrants for which a ready market is unavailable may cause estimated values of these warrant assets to differ significantly from the values that would have been derived had a ready market for the warrant assets existed, and those differences could be material. The use of an alternative valuation methodology or alternative approaches used to calculate material assumptions could result in significantly different estimated values for these assets. In addition, the value of all warrants required to be carried at fair value is at risk to changes in equity markets, general economic conditions and other factors. The valuation of warrants may be impacted by the adoption of SFAS No. 157, “Fair Value Measurement,” (SFAS 157). For further discussion of SFAS 157, refer to Note 2 to the consolidated financial statements on page 79.

Note 1 — Summary of Significant Accounting Policies

Organization

Comerica Incorporated (the Corporation) is a registered financial holding company headquartered in Dallas, Texas. The Corporation’s major business segments are the Business Bank, the Retail Bank and Wealth & Institutional Management. For further discussion of each business segment, refer to Note 24 on page 119. The core businesses are tailored to each of the Corporation’s four primary geographic markets: Midwest, Western, Texas and Florida. The Corporation and its banking subsidiaries are regulated at both the state and federal levels.

The accounting and reporting policies of the Corporation conform to U.S. generally accepted accounting principles and prevailing practices within the banking industry. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.

The following summarizes the significant accounting policies of the Corporation applied in the preparation of the accompanying consolidated financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of the Corporation and its subsidiaries after elimination of all significant intercompany accounts and transactions. Certain amounts in the financial statements for prior years have been reclassified to conform to current financial statement presentation.

The Corporation consolidates variable interest entities (VIE’s) in which it is the primary beneficiary. In general, a VIE is an entity that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. If any of these characteristics is present, the entity is subject to a variable interests consolidation model, and consolidation is based on variable interests, not on ownership of the entity’s outstanding voting stock. Variable interests are defined as contractual, ownership or other money interests in an entity that change with fluctuations in the entity’s net asset value. The primary beneficiary consolidates the VIE; the primary beneficiary is defined as the enterprise that absorbs a majority of expected losses or receives a majority of residual returns (if the losses or returns occur), or both. The Corporation consolidates entities not determined to be VIE’s when it holds a majority (controlling) interest in the entity’s outstanding voting stock. The minority interest in less than 100% owned consolidated subsidiaries is not material and is included in “accrued expenses and other liabilities” on the consolidated balance sheets. The related minority interest in earnings which is included in “other noninterest expenses” on the consolidated statements of income was a credit of $1 million for the year ended December 31, 2007, not significant for the year ended December 31, 2006 and an expense of $4 million for the year ended December 31, 2005.

Equity investments in entities that are not VIE’s where the Corporation owns less than a majority (controlling) interest and equity investments in entities that are VIE’s where the Corporation is not the primary beneficiary are not consolidated. Rather, such investments are accounted for using either the equity method or cost method. The equity method is used for investments in a corporate joint venture and investments where the Corporation has the ability to exercise significant influence over the investee’s operation and financial policies, which is generally presumed to exist if the Corporation owns more than 20 percent of the voting interest of the investee. Equity method investments are included in “accrued income and other assets” on the consolidated balance sheets, with income and losses recorded in “other noninterest income” on the consolidated statements of income. Unconsolidated equity investments that do not meet the criteria to be accounted for under the equity method are accounted for under the cost method. Cost method investments in publicly traded companies are

72

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

included in “investment securities available-for-sale” on the consolidated balance sheets, with income (net of write-downs) recorded in “net securities gains (losses)” on the consolidated statements of income. Cost method investments in non-publicly traded companies are included in “accrued income and other assets” on the consolidated balance sheets, with income (net of write-downs) recorded in “other noninterest income” on the consolidated statements of income.

For further information regarding the Corporation’s investments in VIE’s, refer to Note 22 on page 114.

Discontinued Operations

Components of the Corporation that have been or will be disposed of by sale, where the Corporation does not have a significant continuing involvement in the operations after the disposal, are accounted for as discontinued operations in all periods presented if significant to the consolidated financial statements. For further information on discontinued operations, refer to Note 26 on page 127.

Short-term Investments

Short-term investments include interest-bearing deposits with banks, trading securities and loansheld-for-sale.

Trading securities are carried at market value. Realized and unrealized gains or losses on trading securities are included in “other noninterest income” on the consolidated statements of income.

Loans held-for-sale, typically residential mortgages, student loans and Small Business Administration loans, are carried at the lower of cost or market. Market value is determined in the aggregate for each portfolio.

Investment Securities

Investment securities held-to-maturity are those securities which the Corporation has the ability and management has the positive intent to hold to maturity as of the balance sheet dates. Investment securities held-to-maturity are stated at cost, adjusted for amortization of premium and accretion of discount.

Investment securities that are not considered held-to-maturity are accounted for as securitiesavailable-for-sale, and stated at fair value, with unrealized gains and losses, net of income taxes, reported as a separate component of other comprehensive income (loss). Unrealized losses on securities available-for-sale are recognized in earnings if, as of the balance sheet date, the Corporation does not have the ability or management does not have the intent to hold the securities until market recovery or if full collection of the amounts due according to the contractual terms of the debt is not expected.

Gains or losses on the sale of securities are computed based on the adjusted cost of the specific security sold.

Allowance for Loan Losses

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 senior management. The Corporation performs a detailed credit quality review quarterly 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. Business loans are 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 estimated 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

73

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

remaining loans based on industry specific risks inherent in certain portfolios that have experienced above average losses. Furthermore, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios that have not yet manifested themselves in the risk ratings. The portion of the allowance allocated to all other consumer and residential mortgage loans is determined by applying estimated loss ratios to various segments of the loan portfolio. Estimated loss ratios for all portfolios incorporate factors, such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and 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 bond tables.

Actual loss ratios 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 estimated 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 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.

Loans deemed uncollectible are charged off and deducted from the allowance. The provision for loan losses and recoveries on loans previously charged off are added to the allowance.

Allowance for Credit Losses on Lending-Related Commitments

The allowance for credit losses on lending-related commitments covers management’s assessment of probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same estimated loss rates as loans, or with specific reserves. In general, the probability of draw for letters of credit is considered certain once the credit becomes a watch list credit (generally consistent with regulatory defined special mention, substandard and doubtful accounts). Non-watch list letters of credits and all unfunded commitments have a lower probability of draw, to which standard loan loss rates are applied. The allowance for credit losses on lending-related commitments is included in “accrued expenses and other liabilities” on the consolidated balance sheets, with the corresponding charge reflected in “provision for credit losses on lending-related commitments” in the noninterest expenses section on the consolidated statements of income.

Nonperforming Assets

Nonperforming assets are comprised of loans and debt securities for which the accrual of interest has been discontinued, loans for which the terms have been renegotiated to less than market rates due to a serious

74

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

weakening of the borrower’s financial condition, and real estate which has been acquired through foreclosure and is awaiting disposition.

Loans that have been restructured but yield a rate equal to or greater than the rate charged for new loans with comparable risk and have met the requirements for accrual status are not reported as nonperforming assets. Such loans continue to be evaluated for impairment for the remainder of the calendar year of the restructuring. These loans may be excluded from the impairment assessment in the calendar years subsequent to the restructuring, if not impaired based on the modified terms. See Note 4 on page 83 for additional information on loan impairment.

Residential mortgage loans are generally placed on nonaccrual status during the foreclosure process, normally no later than 150 days past due. Other consumer loans are generally not placed on nonaccrual status and are charged off no later than 180 days past due, and earlier, if deemed uncollectible. Loans, other than consumer loans, and debt securities are generally placed on nonaccrual status when principal or interest is past due 90 days or moreand/or when, in the opinion of management, full collection of principal or interest is unlikely. At the time a loan or debt security is placed on nonaccrual status, interest previously accrued but not collected is charged against current income. Income on such loans and debt securities is then recognized only to the extent that cash is received and where future collection of principal is probable. Generally, a loan or debt security may be returned to accrual status when all delinquent principal and interest have been received and the Corporation expects repayment of the remaining contractual principal and interest, or when the loan or debt security is both well secured and in the process of collection.

A nonaccrual loan that is restructured will generally remain on nonaccrual after the restructuring for a period of six months to demonstrate that the borrower can meet the restructured terms. However, sustained payment performance prior to the restructuring or significant events that coincide with the restructuring are included in assessing whether the borrower can meet the restructured terms. These factors may result in the loan being returned to an accrual status at the time of restructuring or upon satisfaction of a shorter performance period. If management is uncertain whether the borrower has the ability to meet the revised payment schedule, the loan remains classified as nonaccrual. Other real estate acquired is carried at the lower of cost or fair value, minus estimated costs to sell. When the property is acquired through foreclosure, any excess of the related loan balance over fair value is charged to the allowance for loan losses. Subsequent write-downs, operating expenses and losses upon sale, if any, are charged to noninterest expenses.

Premises and Equipment

Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation, computed on the straight-line method, is charged to operations over the estimated useful lives of the assets. The estimated useful lives are generally10-33 years for premises that the Corporation owns and three to eight years for furniture and equipment. Leasehold improvements are amortized over the terms of their respective leases, or 10 years, whichever is shorter.

Software

Capitalized software is stated at cost, less accumulated amortization. Capitalized software includes purchased software and capitalizable application development costs associated with internally-developed software. Amortization, computed on the straight-line method, is charged to operations over the estimated useful life of the software, which is generally five years. Capitalized software is included in “accrued income and other assets” on the consolidated balance sheets.

Goodwill and Other Intangible Assets

Goodwill and identified intangible assets that have an indefinite useful life are subject to impairment testing, which is conducted annually, or on an interim basis if events or changes in circumstances between annual tests indicate the assets might be impaired. The Corporation performs its annual impairment test for goodwill as of July 1 of each year. The impairment test involves assigning tangible assets and liabilities, identified intangible assets and goodwill to reporting units, which are a subset of the Corporation’s operating segments, and comparing the fair value of each reporting unit to its carrying value. If the fair value is less than the carrying value, a further test is required to measure the amount of impairment.

The Corporation reviews finite-lived intangible assets and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable from projected undiscounted net operating cash flows. If the projected undiscounted net operating cash flows are less than the carrying amount, a loss is recognized to reduce the carrying amount to fair value.

Additional information regarding goodwill, other intangible assets and impairment policies can be found in Note 8 on page 86.

Share-based Compensation

In 2006, the Corporation adopted the provisions of SFAS No. 123 (revised 2004) (SFAS 123(R)), “Share-Based Payment,” using the modified-prospective transition method. Compensation expense is recognized under SFAS 123(R) using the straight-line method over the requisite service period. Measurement and attribution of compensation cost for awards that were granted prior to the date SFAS 123(R) was adopted continue to be based on the estimate of the grant-date fair value and attribution method used under prior accounting guidance. Prior to the adoption of SFAS 123(R), the benefit of tax deductions in excess of recognized compensation costs was reported in net cash provided by operating activities in the consolidated statements of cash flows. SFAS 123(R) requires such excess tax benefits be reported as a cash inflow from financing activities, rather than a cash flow from operating activities; therefore, these amounts for the years ended December 31, 2007 and 2006, are reported in net cash provided by financing activities in the consolidated statements of cash flows.

In 2002, the Corporation adopted the fair value recognition provisions of SFAS 123, “Accounting for Stock-Based Compensation” (SFAS 123) (as amended by SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure”), which the Corporation applied prospectively to new share-based compensation awards granted to employees after December 31, 2001. Options granted prior to January 1, 2002 were accounted for under the intrinsic value method, as outlined in APB Opinion No. 25, “Accounting for Stock Issued to Employees.” Net income and earnings per share for the years ended December 31, 2007 and 2006 fully reflect the impact of applying the fair value recognition method to all outstanding and unvested awards. There would have been no effect on reported net income and earnings per share if the fair value method required by SFAS 123 (as amended by SFAS 148) had been applied to all outstanding and unvested awards in 2005.

SFAS 123(R) requires that the expense associated with share-based compensation awards be recorded over the requisite service period. The requisite service period is the period an employee is required to provide service in order to vest in the award, which cannot extend beyond the retirement eligible date (the date at which the employee is no longer required to perform any service to receive the share-based compensation). Prior to the adoption of SFAS 123(R), the Corporation recorded the expense associated with share-based compensation awards over the explicit service period (vesting period). Upon retirement, any remaining unrecognized costs related to share-based compensation awards retained after retirement were expensed.

The Corporation elected to adopt the alternative transition method provided in the Financial Accounting Standards Board (FASB) Staff Position No. FAS 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards,” for calculating the tax effects of share-based compensation under SFAS 123(R). The alternative transition method included simplified methods to establish the beginning balance

76

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

of the additional paid-in capital pool (APIC pool) related to the tax effects of employee share-based compensation, and to determine the subsequent impact on the APIC pool and consolidated statements of cash flows of the tax effects of employee share-based compensation awards that were outstanding and fully or partially unvested upon adoption of SFAS 123(R).

Further information on the Corporation’s share-based compensation plans is included in Note 15 on page 95.

Pension and Other Postretirement Costs

On December 31, 2006, the Corporation adopted the provisions 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),” (SFAS 158), and recognized in its consolidated balance sheet the funded status of its defined benefit pension and postretirement plans, measured as the difference between the fair value of plan assets and the benefit obligation. For a pension plan, the benefit obligation is the projected benefit obligation; for any other postretirement plan, the benefit obligation is the accumulated benefit obligation. The Corporation also recorded prior service costs, net actuarial losses and remaining transition obligations as components of accumulated other comprehensive income (loss), net of tax, at December 31, 2006. Actuarial gains or losses and prior service costs or credits that arise subsequent to December 31, 2006 are recognized as increases or decreases in other comprehensive income (loss).

Pension costs are charged to “employee benefits” expense on the consolidated statements of income and are funded consistent with the requirements of federal laws and regulations. Inherent in the determination of pension costs are assumptions concerning future events that will affect the amount and timing of required benefit payments under the plans. These assumptions include demographic assumptions such as retirement age and death, a compensation rate increase, a discount rate used to determine the current benefit obligation and a long-term expected return on plan assets. Net periodic pension expense includes service cost, interest cost based on the assumed discount rate, an expected return on plan assets based on an actuarially derived market-related value of assets, amortization of prior service cost and amortization of net actuarial gains or losses. The market-related value used to determine the expected return on plan assets is based on fair value adjusted for the difference between expected returns and actual asset performance. The asset gains and losses are incorporated in the market-related value over a five-year period. Prior service costs include the impact of plan amendments on the liabilities and are amortized over the future service periods of active employees expected to receive benefits under the plan. Actuarial gains and losses result from experience different from that assumed and from changes in assumptions (excluding asset gains and losses not yet reflected in market-related value). Amortization of actuarial gains and losses is included as a component of net periodic pension cost for a year if the actuarial net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets. If amortization is required, the excess is amortized over the average remaining service period of participating employees expected to receive benefits under the plan.

Postretirement benefits are recognized in “employee benefits” expense on the consolidated statements of income during the average remaining service period of participating employees expected to receive benefits under the plan or the average remaining future lifetime of retired participants currently receiving benefits under the plan.

For further information regarding SFAS 158 and the Corporation’s pension and other postretirement plans refer to Note 16 on page 97.

Derivative Instruments

Derivative instruments are carried at fair value in either, “accrued income and other assets” or “accrued expenses and other liabilities” on the consolidated balance sheets. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments

77

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

that are designated and qualify as hedging instruments, the Corporation designates the hedging instrument, based upon the exposure being hedged, as either a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. For derivative instruments designated and qualifying as a fair value hedge (i.e., hedging the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item (i.e., the ineffective portion), if any, is recognized in current earnings during the period of change. For derivative instruments that are designated and qualify as a hedge of a net foreign currency investment in a foreign subsidiary, the gain or loss is reported in other comprehensive income as part of the cumulative translation adjustment to the extent it is effective. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in current earnings during the period of change.

If the Corporation determines that a derivative instrument has not been or will not continue to be highly effective as a fair value or cash flow hedge, or that the hedge designation is no longer appropriate, hedge accounting is discontinued. The derivative instrument will continue to be recorded in the consolidated balance sheets at its fair value, with future changes in fair value recognized in noninterest income.

Foreign exchange futures and forward contracts, foreign currency options, interest rate caps, interest rate swap agreements and energy derivative contracts executed as a service to customers are not designated as hedging instruments and both the realized and unrealized gains and losses on these instruments are recognized in noninterest income.

The Corporation holds a portfolio of warrants for non-marketable equity securities. Most of these warrants are from high technology, non-public companies obtained as part of the loan origination process. Warrants that have a net exercise provision embedded in the warrant agreement (primarily those obtained prior to 2006) are required to be accounted for as derivatives and recorded at fair value. The initial fair value of warrants obtained as part of the loan origination process is deferred and amortized into “interest and fees on loans” on the consolidated statements of income over the life of the loan. The fair value of these warrants is subsequently adjusted on a quarterly basis, with any changes in fair value recorded in “net income from principal investing and warrants” on the consolidated statements of income. Prior to 2005, the Corporation recognized income related to these warrants approximately 30 days prior to the warrant issuer’s publicly traded stock becoming free of restrictions, when a publicly traded company acquired the warrant issuer, or when cash was received. The cumulative adjustment to record the fair value was not material to 2005 or any other prior reporting period.

Further information on the Corporation’s derivative instruments is included in Note 20 on page 107.

Standby and Commercial Letters of Credit and Financial Guarantees

A liability related to certain guarantee contracts or indemnification agreements that contingently require the guarantor to make payments to the guaranteed party is recognized and initially measured at fair value by the guarantor. The initial recognition and measurement provisions were applied by the Corporation on a prospective basis to guarantees issued or modified subsequent to December 31, 2002. Further information on the Corporation’s obligations under guarantees is included in Note 20 on page 107.

Income Taxes

The provision for income taxes is based on amounts reported in the consolidated statements of income (after deducting non-taxable items, principally income on bank-owned life insurance, and deducting tax credits related to investments on low income housing partnerships) and includes deferred income taxes on temporary differences between the tax basis and financial reporting basis of assets and liabilities. Deferred tax assets are evaluated for realization based on available evidence and assumptions made regarding future events. This evaluation includes assumptions of future taxable income and other likely initiatives that could be undertaken. 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 provision for income taxes assigned to discontinued operations is based on statutory rates, adjusted for permanent differences generated by those operations.

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. For all prior periods presented, interest and penalties on tax liabilities remained classified in “other noninterest expenses” on the consolidated statements of income. For a further discussion of FIN 48 refer to Note 17 to the consolidated financial statements on page 103.

Statements of Cash Flows

Cash and cash equivalents are defined as those amounts included in “cash and due from banks” on the consolidated balance sheets. Cash flows from discontinued operations are reported as separate line items within cash flows from operating, investing and financing activities in the consolidated statements of cash flows.

Deferred Distribution Costs

Certain mutual fund distribution costs, principally commissions paid to brokers, are capitalized when paid and amortized over six years. Fees that contractually recoup the deferred costs, primarily12b-1 fees, are received over a 6-8 year period. The net of these fees and amortization is recorded on the consolidated statements of income. Early redemption fees collected are generally recorded as a reduction to the capitalized costs, unless there is evidence that, on an ongoing basis, amounts collected will exceed the unamortized deferred fee asset.

Loan Origination Fees and Costs

Business loan origination and commitment fees greater than $10 thousand and all Small Business Administration loan, residential mortgage and consumer loan origination fees and costs are deferred and recognized over the life of the related loan or over the commitment period as a yield adjustment. Loan fees on unused commitments and net origination fees related to loans sold are recognized currently as noninterest income.

Other Comprehensive Income (Loss)

The Corporation has elected to present information on comprehensive income in the consolidated statements of changes in shareholders’ equity on page 70 and in Note 13 on page 92.

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

79

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

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. While not expanding the use of fair value, SFAS 157 may change the measurement of fair value. Any change in the measurement of fair value would be considered a change in estimate and included in the results of operations in the period of adoption. 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 does not expect the adoption of the provisions of SFAS 157 to have a material effect 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 acontract-by-contract basis. The Corporation can elect to apply the standard prospectively and measure certain financial instruments at fair value beginning January 1, 2008. 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. After adoption, all changes in fair value would be included in the results of operations. The Corporation has evaluated the guidance contained in SFAS 159, and has decided not to elect the fair value option for any financial assets or liabilities at this time.

In December 2007, the FASB issued SFAS No. 141(revised 2007), “Business Combinations,” (SFAS 141(R)), which replaces SFAS 141. SFAS 141(R) establishes principles and requirements for recognition and measurement of assets, liabilities and any noncontrolling interest acquired due to a business combination. SFAS 141(R) expands the definitions of a business and a business combination, resulting in an increased number of transactions or other events that will qualify as business combinations. Under SFAS 141(R) the entity that acquires the business (the “acquirer”) will record 100% of all assets and liabilities of the acquired business, including goodwill, generally at their fair values. SFAS 141(R) requires the acquirer to recognize goodwill as of the acquisition date, measured as a residual. In most business combinations, goodwill will be recognized to the extent that the consideration transferred plus the fair value of any noncontrolling interests in the acquiree at the acquisition date exceeds the fair values of the identifiable net assets acquired. Under SFAS 141(R) acquisition-related transaction and restructuring costs will be expensed as incurred rather than treated as part of the cost of the acquisition and included in the amount recorded for assets acquired. SFAS 141(R) is effective for fiscal years beginning after December 15, 2008. Accordingly, for acquisitions completed after December 31, 2008, the Corporation will apply the provisions of SFAS 141(R).

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements, an amendment of ARB 51,” (SFAS 160), which defines noncontrolling interest as the portion of equity in a subsidiary not attributable, direct or indirectly, to the parent. SFAS 160 requires the ownership interests in subsidiaries held by parties other than the parent (previously referred to as minority interest) to be clearly presented in the consolidated statement of financial position within equity, but separate from the parent’s equity. The amount of consolidated net income attributable to the parent and to any noncontrolling interest must be clearly presented on the face of the consolidated statement of income. Changes in the parent’s ownership interest while the parent retains its controlling financial interest (greater than 50 percent ownership) are to be accounted for as equity transactions. Upon a loss of control, any gain or loss on the interest sold will be recognized in earnings. Additionally, any ownership interest retained will be remeasured at fair value on the date control is lost, with any gain or loss recognized in earnings. SFAS 160 is effective for fiscal years beginning after December 15, 2008. Accordingly, the Corporation will adopt the provisions of SFAS 160 in the first quarter 2009. The

At December 31, 2007, the Corporation had 122 securities in an unrealized loss position, including 120 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 December 31, 2007.

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.

Note 4 — Nonperforming Assets

The following table summarizes nonperforming assets and loans, which generally are contractually past due 90 days or more as to interest or principal payments. Nonperforming assets consist of nonaccrual loans, reduced-rate loans and real estate acquired through foreclosure. Nonaccrual loans are those on which interest is not being recognized. Reduced-rate loans are those on which interest has been renegotiated to lower than market rates because of the weakened financial condition of the borrower.

Nonaccrual and reduced-rate loans are included in loans on the consolidated balance sheets and real estate acquired through foreclosure is included in “accrued income and other assets” on the consolidated balance sheets.

A loan is impaired when it is probable that payment of interest and principal 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 at December 31, 2007 were $404 million. Restructured loans which are performing in accordance with their modified terms must be disclosed as impaired for the remainder of the calendar year of the restructuring, in accordance with impaired loan disclosure requirements. Loans restructured during the year which met the requirements to be on accrual status at December 31, 2007, totaled $4 million.

Those impaired loans not requiring an allowance represent loans for which the fair value of expected repayments or collateral exceeded the recorded investments in such loans. At December 31, 2007, substantially all of the total impaired loans were evaluated based on fair value of related collateral. Remaining loan impairment is based on the present value of expected future cash flows discounted at the loan’s effective interest rate or observable market value.

Note 6 — Significant Group Concentrations of Credit Risk

Concentrations of both on-balance sheet and off-balance sheet credit risk are controlled and monitored as part of credit policies. The Corporation is a regional financial services holding company with a geographic concentration of its on-balance sheet and off-balance sheet activities in Michigan, California and Texas.

The Corporation has an industry concentration with the automotive industry. Loans to automotive dealers and to borrowers involved with automotive production are reported as automotive, since management believes these loans have similar economic characteristics that might cause them to react similarly to changes in economic conditions. This aggregation involves the exercise of judgment. Included in automotive production are: (a) original equipment manufacturers and Tier 1 and Tier 2 suppliers that produce components used in vehicles and

whose primary revenue source is automotive-related (“primary” defined as greater than 50%) and (b) other manufacturers that produce components used in vehicles and whose primary revenue source is automotive-related. Loans less than $1 million and loans recorded in the Small Business division were excluded from the definition. Outstanding loans and total exposure from loans, unused commitments and standby letters of credit and financial guarantees to companies related to the automotive industry were as follows:

Note 8 — Goodwill and Other Intangible Assets

Goodwill and identified intangible assets that have an indefinite useful life are subject to impairment testing, which the Corporation conducts annually, or on an interim basis if events or changes in circumstances between annual tests indicate the assets might be impaired. The annual test of goodwill and intangible assets that have an indefinite life, performed as of July 1, 2007 and 2006, did not indicate that an impairment charge was required.

In the fourth quarter 2006, the Corporation sold its ownership interest in Munder, a consolidated subsidiary that was part of the Corporation’s asset management reporting unit. Goodwill of $63 million was allocated to the sale in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets” (SFAS 142). Following the sale of Munder, the remaining components of the asset management reporting unit, which were not significant, were combined with another reporting unit and tested for impairment. The test did not indicate an impairment charge was required. The Corporation has accounted for Munder as a discontinued operation in all periods presented, which is included in the “Other” category for business segment reporting purposes. For additional information regarding discontinued operations, refer to Note 26 on page 127.

In July 2007, the Corporation issued $150 million of floating rate medium-term senior notes due July 27, 2010. The notes pay interest quarterly, beginning October 27, 2007. The notes bear interest at a variable rate reset each interest period based on three-month LIBOR plus 0.17%. The Corporation used the proceeds to repay the $150 million 7.25% subordinated note due 2007. These medium-term notes do not qualify as Tier 2 capital and are not insured by the FDIC.

In June 2007, the Corporation exercised its option to redeem a $55 million, 9.98% subordinated note, which had an original maturity date of 2026.

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 semiannually, beginning May 21, 2007, and mature November 21, 2016. The Bank used the net proceeds for general corporate purposes.

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 semiannually, 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 until the scheduled maturity date of February 20, 2037. The Corporation used the proceeds for the redemption of a $350 million, 7.60% subordinated note due 2050 and to repurchase additional shares. The 6.576% subordinated notes qualify as Tier 1 capital. All other subordinated notes with maturities greater than one year qualify as Tier 2 capital.

In November 2006, the Bank issued $400 million of 5.75% subordinated notes. The notes pay interest semiannually, beginning May 21, 2007, and mature November 21, 2016. The Bank used the net proceeds for general corporate purposes.

In February 2006, the Bank issued an additional $250 million of 5.20% subordinated notes under a series initiated in August 2005. The notes pay interest semiannually, beginning August 22, 2006, and mature August 22, 2017. The Bank used the net proceeds for general corporate purposes.

The Corporation currently has a $15 billion medium-term senior note program. This program allows the principal banking subsidiary to issue fixed or floating rate notes with maturities between one and 30 years. The Bank issued a total of $3.4 billion and $2.7 billion of floating rate bank notes during the years ended December 31, 2007 and 2006, respectively, under the senior note program, using the proceeds for general corporate purposes. The interest rate on the floating rate medium-term notes based on LIBOR at December 31, 2007 ranged from one-month LIBOR less 0.01% to three-month LIBOR plus 0.19%. The interest rate on the floating rate medium-term notes based on PRIME at December 31, 2007 ranged from PRIME less 2.91% to PRIME less 2.38%. The interest rate on the floating rate medium-term note based on the Federal Funds rate at December 31, 2007 was Federal Funds plus 0.21%. The medium-term notes outstanding at December 31, 2007 are due from 2008 to 2012. The medium-term notes do not qualify as Tier 2 capital and are not insured by the FDIC.

In February 2008, the Bank became a member of the Federal Home Loan Bank of Dallas, Texas (FHLB), which provides short-and long-term funding to its members though advances that are collateralized by mortgage-related assets.

Note 12 — Shareholders’ Equity

The Board of Directors of the Corporation authorized the purchase up to 10 million shares of Comerica Incorporated outstanding common stock on November 13, 2007, in addition to the remaining unfilled portion of November 14, 2006 authorization. There is no expiration date for the Corporation’s share repurchase program. Substantially all shares purchased as part of the Corporation’s publicly announced repurchase program were transacted in the open market and were within the scope ofRule 10b-18, which provides a safe harbor for purchases in a given day if an issuer of equity securities satisfies the manner, timing, price and volume conditions of the rule when purchasing its own common shares in the open market. Open market repurchases totaled 10.0 million shares, 6.6 million shares and 9.0 million shares in the years ended December 31, 2007, 2006 and

(1)	Includes shares purchased as part of publicly announced repurchase plans or programs, shares purchased pursuant to deferred compensation plans and shares purchased from employees to pay for grant prices and/or taxes related to stock option exercises and restricted stock vesting under the terms of an employee share-based compensation plan.
(2)	Maximum number of shares that may yet be purchased under the publicly announced plans or programs.
(3)	Remaining share repurchase authorization includes the November 13, 2007 Board of Directors resolution for the repurchase of an additional 10 million shares.

At December 31, 2007, the Corporation had 30.1 million shares of common stock reserved for issuance and 1.3 million shares of restricted stock outstanding to employees and directors under share-based compensation plans.

Note 13 — 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 70 include only combined other comprehensive income (loss), net of tax. The following table presents reconciliations of the components of accumulated other comprehensive income (loss) for the years ended December 31, 2007, 2006 and 2005. Total comprehensive income totaled $833 million, $948 million and $760 million for the years ended December 31, 2007, 2006 and 2005, respectively. The $115 million decrease in total comprehensive income in the year ended December 31, 2007, when compared to 2006, resulted principally from a decrease in net income ($207 million), partially offset by a decrease in net unrealized losses on investment securities available-for-sale ($44 million) due to changes in the interest rate environment, an increase in net gains on cash flow hedges ($7 million) and the change in the defined benefit and other postretirement benefit plans adjustment ($45 million). Accumulated other comprehensive income at December 31, 2006 was impacted by a $209 million after-tax transition adjustment to apply the provisions of SFAS 158.

Note 14 — Net Income Per Common Share

Basic income from continuing operations and net income per common share are computed by dividing income from continuing operations and net income applicable to common stock, respectively, by the weighted-average number of shares of common stock outstanding during the period. Diluted income from continuing operations and net income per common share are computed by dividing income from continuing operations and net income applicable to common stock, respectively, by the weighted-average number of shares, nonvested restricted stock and dilutive common stock equivalents outstanding during the period. Common stock equivalents consist of common stock issuable under the assumed exercise of stock options granted under the Corporation’s stock plans, using the treasury stock method. A computation of basic and diluted income from continuing operations and net income per common share are presented in the following table.

Note 15 — Share-Based Compensation

Share-based compensation expense is charged to “salaries” expense, except for the Corporation’s Munder subsidiary, which was sold in 2006, whose share-based compensation expense was charged to “income from discontinued operations, net of tax,” on the consolidated statements of income.

Weighted-average expected recognition period (in years)		2.4

The Corporation has share-based compensation plans under which it awards both shares of restricted stock to key executive officers and key personnel, and stock options to executive officers, directors and key personnel of the Corporation and its subsidiaries. Restricted stock vests over periods ranging from three to five years. Stock options vest over periods ranging from one to four years. The maturity of each option is determined at the date of grant; however, no options may be exercised later than ten years and one month from the date of grant. The options may have restrictions regarding exercisability. The plans originally provided for a grant of up to 13.2 million common shares, plus shares under certain plans that are forfeited, expire or are cancelled. At December 31, 2007, 10.9 million shares were available for grant.

The Corporation used a binomial model to value substantially all stock options granted in the periods presented. Previously, a Black-Scholes option-pricing model was used. Option valuation models require several inputs, including the expected stock price volatility, and changes in input assumptions can materially affect the fair value estimates. The model used may not necessarily provide a reliable single measure of the fair value of employee and director stock options. The risk-free interest rate assumption used in the binomial option-pricing model as outlined in the table below was based on the federal ten-year treasury interest rate. The expected dividend yield was based on the historical and projected dividend yield patterns of the Corporation’s common shares. Expected volatility assumptions during 2007 and 2006 considered both the historical volatility of the Corporation’s common stock over a ten-year period and implied volatility based on actively traded options on the Corporation’s common stock with pricing terms and trade dates similar to the stock options granted. In 2005, only historical volatility was considered under the binomial model. The expected life of employee and director stock options, which is an output of the binomial model, considered the percentage of vested shares estimated to be cancelled over the life of the grant and was based on the historical exercise behavior of the option holders.

The fair value of options granted subsequent to March 31, 2005 was estimated using the binomial option-pricing model with the following weighted-average assumptions:

							Period from
	Year Ended			Year Ended			April 1, 2005
	December 31,			December 31,			to December 31,
	2007			2006			2005
Risk-free interest rates		4.88	%		4.69	%		4.44	%
Expected dividend yield		3.85			3.85			3.85
Expected volatility factors of the market price of Comerica common stock		23			24			29
Expected option life (in years)		6.4			6.5			6.5

The weighted-average grant-date fair values per option share granted, based on the assumptions above, were $12.47, $12.25, and $13.56 in 2007, 2006 and 2005, respectively.

A summary of the Corporation’s stock option activity and related information for the year ended December 31, 2007 follows:

				Weighted-Average

	Number of			Exercise Price		Contractual		Aggregate
	Options			per Share		Term		Intrinsic Value

Exercisable — December 31, 2007		13,160		$	56.48		3.9	$	7

The aggregate intrinsic value of outstanding options shown in the table above represents the total pretax intrinsic value at December 31, 2007, based on the Corporation’s closing stock price of $43.53 as of December 31, 2007. The total intrinsic value of stock options exercised was $33 million, $26 million and $31 million for the years ended December 31, 2007, 2006 and 2005, respectively.

Cash received from the exercise of stock options during 2007, 2006 and 2005 totaled $89 million, $45 million and $42 million, respectively. The net excess income tax benefit realized for the tax deductions from the exercise of these options during the years ended December 31, 2007, 2006 and 2005 totaled $8 million, $8 million and $9 million, respectively.

The total fair value of restricted stock awards that fully vested during the years ended December 31, 2007, 2006 and 2005 was $10 million, $8 million and $1 million, respectively.

The Corporation expects to satisfy the exercise of stock options and future grants of restricted stock by issuing shares of common stock out of treasury. At December 31, 2007, the Corporation held 28.7 million shares in treasury.

For further information on the Corporation’s share-based compensation plans, refer to Note 1 on page 72.

Note 16 — Employee Benefit Plans

The Corporation has a qualified and a non-qualified defined benefit pension plan, which together, provide benefits for substantially all full-time employees hired before January 1, 2007. Employee benefits expense included pension expense of $36 million, $39 million and $31 million in the years ended December 31, 2007, 2006 and 2005, respectively, for the plans. Benefits under the defined benefit plans are based primarily on years of service, age and compensation during the five highest paid consecutive calendar years occurring during the last ten years before retirement. The defined benefit plans’ assets primarily consist of units of certain collective investment funds and mutual investment funds administered by Munder Capital Management, equity securities, U.S. Treasury and other Government agency securities, Government-sponsored enterprise securities, and corporate bonds and notes. The majority of these assets have publicly quoted prices, which is the basis for determining fair value of plan assets.

On January 1, 2007, the Corporation added a defined contribution feature to its principal defined contribution plan for the benefit of substantially all full-time employees hired on or after January 1, 2007. Under the defined contribution feature, the Corporation will make an annual contribution to the individual account of each eligible employee ranging from three to eight percent of annual compensation, determined based on combined age and years of service. The contributions will be invested based on employee investment elections. The employee fully vests in the defined contribution account after three years of service. The plan feature, effective January 1, 2007, requires one year of service before an employee is eligible to participate. As a result, no pension expense was incurred for this plan feature for the year ended December 31, 2007.

The Corporation’s postretirement benefit plan continues to provide postretirement health care and life insurance benefits for retirees as of December 31, 1992. The plan also provides certain postretirement health care and life insurance benefits for a limited number of retirees who retired prior to January 1, 2000. For all other employees hired prior to January 1, 2000, a nominal benefit is provided. Employees hired on or after January 1, 2000 are not eligible to participate in the plan. The Corporation has funded the plan with bank-owned life insurance.

The long-term rate of return expected on plan assets is set after considering both long-term returns in the general market and long-term returns experienced by the assets in the plan. The returns on the various asset categories are blended to derive one long-term rate of return. The Corporation reviews its pension plan assumptions on an annual basis with its actuarial consultants to determine if assumptions are reasonable and adjusts the assumptions to reflect changes in future expectations.

Plan Assets

The Corporation’s qualified defined benefit pension plan asset allocations at December 31, 2007 and 2006 and target allocation for 2008 are shown in the table below. There were no assets in the non-qualified defined benefit pension plan. The postretirement benefit plan is fully invested in bank-owned life insurance policies.

	Qualified Defined Benefit Pension Plan
	Target			Percentage of Plan Assets at
	Allocation			December 31
Asset Category	2008			2007			2006
Equity securities		55	— 65%		61	%		63	%
Fixed income, including cash		30	— 40		39			37
Alternative assets		0	— 5		—			—
Total					100	%		100	%

The investment goal for the qualified defined benefit pension plan is to achieve a real rate of return (nominal rate minus consumer price index change) consistent with that received on investment grade corporate bonds. The Corporation’s 2008 target allocation percentages by asset category are noted in the table above. Given the mix of equity securities and fixed income (including cash), management believes that by targeting the benchmark return to an “investment grade” quality return, an appropriate degree of risk is maintained. Within the asset classes, the degree ofnon-U.S. based assets is limited to 15 percent of the total, to be allocated within both equity securities and fixed income. The investment manager has discretion to make investment decisions within the target allocation parameters. The Corporation’s Employee Benefits Committee must approve exceptions to this policy. Securities issued by the Corporation and its subsidiaries are not eligible for use within this plan.

The Corporation also maintains other defined contribution plans (including 401(k) plans) for various groups of its employees. Substantially all of the Corporation’s employees are eligible to participate in one or more of the plans. Under the Corporation’s principal defined contribution plan, the Corporation makes matching cash contributions. Effective January 1, 2007, the Corporation prospectively changed its core matching contribution to 100 percent of the first four percent of qualified earnings contributed (up to the current IRS compensation limit), invested based on employee investment elections. Previously, the Corporation’s matches were based on a declining percentage of employee contributions as well as a performance-based matching contribution. Under the prior plan, the matching contributions were made in the stock of the Corporation and were restricted until the end of the calendar year. Employee benefits expense included expense for the plans of $20 million, $13 million and $15 million in the years ended December 31, 2007, 2006 and 2005, respectively.

Note 17 — Income Taxes and Tax-Related Items

The provision for federal income taxes is computed by applying the statutory federal income tax rate to income before income taxes as reported in the consolidated financial statements after deducting non-taxable items, principally income on bank-owned life insurance, and deducting tax credits related to investments in low income housing partnerships. State and foreign taxes are then added to the federal tax provision. In addition, beginning January 1, 2007, interest and penalties on tax liabilities are 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 $18 million at January 1, 2007, accounted for as a change in accounting principle via a decrease to the opening balance of retained earnings ($13 million, net of tax). At January 1, 2007, the Corporation had unrecognized tax benefits of approximately $85 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 $75 million at January 1, 2007, and $77 million at December 31, 2007.

A reconciliation of the beginning and ending amount of unrecognized tax benefit follows:

	Unrecognized
	Tax Benefits
	(in millions)
Balance at January 1, 2007	$	85
Increases as a result of tax positions taken during a prior period		3

Decreases related to settlements with tax authorities		(4	)
Decreases as a result of a lapse of the applicable statute of limitations		—
Balance at December 31, 2007	$	88

The Corporation recognized approximately $5 million in interest and penalties on tax liabilities included in the “provision for income taxes” on the consolidated statements of income for the year ended December 31, 2007, compared to $38 million for the year ended December 31, 2006 and $11 million for the year ended December 31, 2005, included in “other noninterest expenses” on the consolidated statements of income. The 2007 interest and penalties on tax liabilities are net of a $9 million reduction of interest resulting from a settlement with the Internal Revenue Service (IRS) on a refund claim. The Corporation had approximately $76 million and $71 million accrued for the payment of interest and penalties at December 31, 2007 and January 1, 2007, respectively. Upon adoption of FIN 48, the Corporation recorded a $7 million (net of tax) decrease to interest and penalties 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 IRS questionsand/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 Corporation continues to exchange information with the IRS Appeals Office related to the structured leasing transactions. 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 and penalties reserves based on settlements discussed. Also, the Corporation has had discussions with various state tax authorities regarding prior year tax filings. The Corporation anticipates that it is reasonably possible that the foreign tax credits and state tax return issues will be settled within the next 12 months resulting in additional payments in the range of $35 to $45 million in 2008.

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, 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 for significant jurisdictions remain subject to examination as of December 31, 2007:

Jurisdiction	Tax Years
Federal	2001-2006
California	2002-2006

On January 1, 2007, the Corporation adopted the provisions of FASB Staff PositionNo. 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.

At December 31, 2007, the Corporation had undistributed earnings of approximately $146 million related to a foreign subsidiary. The Corporation intends to reinvest theses earnings indefinitely and has not recorded any related federal or state income tax expense. If these earnings were repatriated to the United States, the Corporation would record additional income tax expense of approximately $53 million.

Note 18 — Transactions with Related Parties

The Corporation’s banking subsidiaries have had, and expect to have in the future, transactions with the Corporation’s directors and executive officers, and companies with which these individuals are associated. Such transactions were made in the ordinary course of business and included extensions of credit, leases and professional services. With respect to extensions of credit, all were made on substantially the same terms, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers and did not, in management’s opinion, involve more than normal risk of collectibility or present other unfavorable features. The aggregate amount of loans attributable to persons who were related parties at December 31, 2007, totaled $210 million at the beginning and $294 million at the end of 2007. During 2007, new loans to related parties aggregated $620 million and repayments totaled $536 million.

Note 19 — Regulatory Capital and Reserve Requirements

Cash and due from banks includes reserves required to be maintainedand/or deposited with the Federal Reserve Bank. These reserve balances vary, depending on the level of customer deposits in the Corporation’s banking subsidiaries. The average required reserve balances were $267 million and $298 million for the years ended December 31, 2007 and 2006, respectively.

Banking regulations limit the transfer of assets in the form of dividends, loans or advances from the bank subsidiaries to the parent company. Under the most restrictive of these regulations, the aggregate amount of dividends which can be paid to the parent company without obtaining prior approval from bank regulatory agencies approximated $234 million at January 1, 2008, plus 2008 net profits. Substantially all the assets of the Corporation’s banking subsidiaries are restricted from transfer to the parent company of the Corporation in the form of loans or advances.

Dividends declared to the parent company of the Corporation by its banking subsidiaries amounted to $614 million, $746 million and $793 million in 2007, 2006 and 2005, respectively.

The Corporation and its U.S. banking subsidiaries are subject to various regulatory capital requirements administered by federal and state banking agencies. Quantitative measures established by regulation to ensure capital adequacy require the maintenance of minimum amounts and ratios of Tier 1 and total capital (as defined in the regulations) to average and risk-weighted assets. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s financial statements. At December 31, 2007 and 2006, the Corporation and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered “well capitalized” (total risk-based capital, Tier 1 risk-based capital and leverage ratios greater than 10 percent, six percent and five percent, respectively). The following is a summary of the capital position of the Corporation and Comerica Bank, its significant banking subsidiary.

Note 20 — 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 credit and market risk.

Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from financial instruments by evaluating the creditworthiness of each counterparty, adhering to the same credit approval process used for traditional lending activities. Counterparty risk limits and monitoring procedures have also been established to facilitate the management of credit risk. Collateral is obtained, if deemed necessary, based on the results of

107

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

management’s credit evaluation. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate.

Derivative instruments are traded over an organized exchange or negotiated over-the-counter. Credit risk associated with exchange-traded contracts is typically assumed by the organized exchange. Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, contain a greater degree of credit risk and liquidity risk than exchange-traded contracts, which have standardized terms and readily available price information. The Corporation reduces exposure to credit and liquidity risks from over-the-counter derivative instruments entered into for risk management purposes, and transactions entered into to mitigate the market risk associated with customer-initiated transactions, by conducting such transactions with investment grade domestic and foreign financial institutions and subjecting counterparties to credit approvals, limits and monitoring procedures similar to those used in making other extensions of credit.

Market risk is the potential loss that may result from movements in interest or foreign currency rates and energy prices, which 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 arising from derivative instruments entered into on behalf of customers is reflected in the consolidated financial statements and may be mitigated by entering into offsetting transactions. Market risk inherent in derivative instruments held or issued for risk management purposes is generally offset by changes in the value of rate sensitive assets or liabilities.

Derivative Instruments

The Corporation, as an end-user, employs a variety of financial instruments for risk management purposes. 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.

For hedge relationships accounted for under SFAS 133 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 133 hedge relationships to which the Corporation does not apply the short-cut method either the dollar offset or statistical regression analysis is used at inception and 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:

Total	$	3	$	1	$	1

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 the Corporation’s

108

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

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 three-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, thus reducing the impact of interest rate changes on future interest income over the next 10 months. Approximately six percent ($3.2 billion) of the Corporation’s outstanding loans were designated as hedged items to interest rate swap agreements at December 31, 2007. For the year ended December 31, 2007, interest rate swap agreements designated as cash flow hedges decreased interest and fees on loans by $67 million, compared with a decrease of $124 million for the year ended December 31, 2006. If interest rates, interest yield curves and notional amounts remain at their current levels, the Corporation expects to reclassify $2 million of net gains, net of tax, on derivative instruments that are designated as cash flow hedges from accumulated other comprehensive income (loss) to earnings during the next 12 months due to receipt of variable interest associated with the 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 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 (loss), with the related amounts due to or from counterparties included in other liabilities or other assets. During the year ended December 31, 2006, the Corporation recognized net gains of less than $0.5 million in accumulated foreign currency translation adjustment, related to the foreign exchange forward and option contracts. The Corporation did not hold any forward foreign exchange contracts recognized in accumulated foreign currency translation adjustment during the year ended December 31, 2007.

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. The Corporation also may use various other types of financial instruments to mitigate interest rate and foreign currency risks associated with specific assets or liabilities. Such instruments include interest rate caps and floors, foreign exchange forward contracts, investment securities, foreign exchange option contracts and foreign exchange cross-currency swaps.

Notional amounts, which represent the extent of involvement in the derivatives market, are generally 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.

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. The amount of this exposure is represented by the gross unrealized gains on derivative instruments.

Bilateral collateral agreements with counterparties covered 63 percent and 76 percent of the notional amount of interest rate derivative contracts at December 31, 2007 and 2006, respectively. These agreements reduce credit risk by providing for the exchange of marketable investment securities to secure amounts due on contracts in an unrealized gain position. In addition, at December 31, 2007, master netting arrangements had been established with all interest rate swap counterparties and certain foreign exchange counterparties. These arrangements effectively reduce credit risk by permitting settlement, on a net basis, of contracts entered into with the same counterparty. The Corporation has not experienced any material credit losses associated with derivative instruments.

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, tenorand/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 aggregatevalue-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 $1 million of net gains in 2007, 2006 and 2005, 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 following table.

Detailed discussions of each class of derivative instruments held or issued by the Corporation for both risk management and customer-initiated and other activities are as follows.

Interest Rate Swaps

Interest rate swaps are agreements in which two parties periodically exchange fixed cash payments for variable payments based on a designated market rate or index (or variable payments based on two different rates or indices for basis swaps), applied to a specified notional amount until a stated maturity. The Corporation’s swap agreements are structured such that variable payments are primarily based on prime, one-month LIBOR or three-month LIBOR. These instruments are principally negotiated over-the-counter and are subject to credit risk, market risk and liquidity risk.

Interest Rate Options, Including Caps and Floors

Option contracts grant the option holder the right to buy or sell an underlying financial instrument for a predetermined price before the contract expires. Interest rate caps and floors are option-based contracts which entitle the buyer to receive cash payments based on the difference between a designated reference rate and the strike price, applied to a notional amount. Written options, primarily caps, expose the Corporation to market risk but not credit risk. A fee is received at inception for assuming the risk of unfavorable changes in interest rates. Purchased options contain both credit and market risk. All interest rate caps and floors entered into by the Corporation are over-the-counter agreements.

Foreign Exchange Contracts

Foreign exchange contracts such as futures, forwards and options are primarily entered into as a service to customers and to offset market risk arising from such positions. Futures and forward contracts require the delivery or receipt of foreign currency at a specified date and exchange rate. Foreign currency options allow the owner to purchase or sell a foreign currency at a specified date and price. Foreign exchange futures are exchange-traded, while forwards, swaps and most options are negotiated over-the-counter. Foreign exchange contracts expose the Corporation to both market risk and credit risk. The Corporation also uses foreign exchange rate swaps and cross-currency swaps for risk management purposes.

Energy Derivative Contracts

The Corporation offers energy derivative contracts, including over-the-counter and NYMEX based natural gas and crude oil fixed rate swaps and options as a service to customers seeking to hedge market risk in the underlying products. Contract tenors are typically limited to three years to accommodate hedge requirements and are further limited to products that are liquid and available on demand. Energy derivative swaps are over-the-counter agreements in which the Corporation and the counterparty periodically exchange fixed cash payments for variable

112

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

payments based upon a designated market price or index. Energy derivative option contracts grant the option owner the right to buy or sell the underlying commodity for a predetermined price at settlement date. Energy caps, floors and collars are option-based contracts that result in the buyer and seller of the contract receiving or making cash payments based on the difference between a designated reference price and the contracted strike price, applied to a notional amount. An option fee or premium is received by the Corporation at inception for assuming the risk of unfavorable changes in energy commodity prices. Purchased options contain both credit and market risk. Commodity options entered into by the Corporation are over-the-counter agreements.

Warrants

The Corporation holds a portfolio of approximately 840 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 on page 72, warrants that have a net exercise provision embedded in the warrant agreement are required to be recorded at fair value. Fair value for these warrants (approximately 570 warrants at December 31, 2007 and 680 warrants at December 31, 2006) was approximately $23 million at December 31, 2007 and $26 million at December 31, 2006, as estimated using a Black-Scholes valuation model.

Commitments

The Corporation also enters into commitments to purchase or sell earning assets for risk management and trading purposes. These transactions are similar in nature to forward contracts. The Corporation had commitments to purchase investment securities for its trading account and available-for-sale portfolios totaling $604 million at December 31, 2007, and commitments to purchase investment securities for its trading account totaling $20 million at December 31, 2006. Commitments to sell investment securities related to the trading account totaled $4 million at December 31, 2007 and $16 million at December 31, 2006. Outstanding commitments expose the Corporation to both credit and market risk.

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.

	December 31
	2007		2006
	(in millions)
Unused commitments to extend credit:
Commercial and other	$	31,603	$	30,410
Bankcard, revolving check credit and equity access loan commitments		2,216		2,147
Total unused commitments to extend credit	$	33,819	$	32,557
Standby letters of credit and financial guarantees:
Maturing within one year	$	4,344	$	4,385
Maturing after one year		2,556		2,199
Total standby letters of credit and financial guarantees	$	6,900	$	6,584
Commercial letters of credit	$	234	$	249

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 December 31, 2007 and 2006, the allowance for credit losses on lending-related commitments, which is recorded

113

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

in “accrued expenses and other liabilities” on the consolidated balance sheets, was $21 million and $26 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.

Standby and Commercial Letters of Credit and Financial Guarantees

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. Long-term standby letters of credit and financial guarantees are defined as those maturing beyond one year and 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 $664 million of the $6.9 billion standby letters of credit outstanding at December 31, 2007. At December 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 $100 million.

Note 21 — Contingent Liabilities

Legal Proceedings

The Corporation and certain of its subsidiaries are subject to various pending and 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 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. For information regarding income tax contingencies, refer to Note 17 on page 103.

Note 22 — Variable Interest Entities (VIE’s)

The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE, and whether the Corporation was the primary beneficiary and should consolidate the entity based on the variable interests it held. The following provides a summary of the VIE’s in which the Corporation has a significant interest.

The Corporation owns 100% of the common stock of an entity formed in 2007 to issue trust preferred securities. This entity meets the definition of a VIE, but the Corporation is not the primary beneficiary. The trust preferred securities held by this entity ($500 million at December 31, 2007) are classified as subordinated debt and qualify as Tier 1 capital. The Corporation is not exposed to loss related to this VIE.

The Corporation has a significant limited partnership interest in The Peninsula Fund Limited Partnership (PFLP), a venture capital fund, which was acquired in 1995. The PFLP’s general partner (an employee of the Corporation) is considered a related party to the Corporation. This entity meets the definition of a VIE, and the Corporation is the primary beneficiary of the entity. As such, the Corporation consolidates PFLP. Creditors of the partnership do not have recourse against the Corporation, and exposure to loss as a result of involvement with PFLP was limited to the book basis in the entity, which was insignificant at December 31, 2007, and approximately $2 million of commitments for future investments.

The Corporation has limited partnership interests in three other venture capital funds, which were acquired in 1998, 1999 and 2001, where the general partner (an employee of the Corporation) in these three partnerships is considered a related party to the Corporation. These three entities meet the definition of a VIE, however, the Corporation is not the primary beneficiary of the entities. As such, the Corporation accounts for its interest in these partnerships on the cost method. These three entities had approximately $157 million in assets at December 31, 2007. Exposure to loss as a result of involvement with these three entities at December 31, 2007 was limited to approximately $5 million of book basis of the Corporation’s investments and approximately $2 million of commitments for future investments.

The Corporation, as a limited partner, also holds an insignificant ownership percentage interest in 129 other venture capital and private equity investment partnerships where the Corporation is not related to the general partner. While these entities may meet the definition of a VIE, the Corporation is not the primary beneficiary of any of these entities as a result of its insignificant ownership percentage interest. The Corporation accounts for its interests in these partnerships on the cost method, and exposure to loss as a result of involvement with these entities at December 31, 2007 was limited to approximately $69 million of book basis of the Corporation’s investments and approximately $38 million of commitments for future investments.

Two limited liability subsidiaries of the Corporation are the general partners in two investment fund partnerships, formed in 1999 and 2003. These subsidiaries manage the investments held by these funds. These two investment partnerships meet the definition of a VIE. In the investment fund partnership formed in 1999, the Corporation is not the primary beneficiary of the entity. As such, the Corporation accounts for its indirect interests in this partnership on the cost method. This investment partnership had approximately $157 million in assets at December 31, 2007 and was structured so that the Corporation’s exposure to loss as a result of its interest should be limited to the book basis of the Corporation’s investment in the limited liability subsidiary, which was insignificant at December 31, 2007. In the investment fund partnership formed in 2003, the Corporation is the primary beneficiary and consolidates the entity. This investment partnership had assets of approximately $10 million at December 31, 2007 and was structured so that the Corporation’s exposure to loss as a result of its interest should be limited to the book basis of the Corporation’s investment in the limited liability subsidiary, which was insignificant at December 31, 2007.

The Corporation has a significant limited partner interest in 20 low income housing tax credit/historic rehabilitation tax credit partnerships, acquired at various times from 1992 to 2007. These entities meet the definition of a VIE. However, the Corporation is not the primary beneficiary of the entities and, as such, accounts for its interest in these partnerships on the cost or equity method. These entities had approximately $137 million in assets at December 31, 2007. Exposure to loss as a result of its involvement with these entities at December 31, 2007 was limited to approximately $16 million of book basis of the Corporation’s investment, which includes unused commitments for future investments.

The Corporation, as a limited partner, also holds an insignificant ownership percentage interest in 106 other low income housing tax credit/historic rehabilitation tax credit partnerships. While these entities may meet the definition of a VIE, the Corporation is not the primary beneficiary of any of these entities as a result of its insignificant ownership percentage interest. As such, the Corporation accounts for its interest in these partnerships on the cost or equity method. Exposure to loss as a result of its involvement with these entities at

December 31, 2007 was limited to approximately $328 million of book basis of the Corporation’s investment, which includes unused commitments for future investments.

For further information on the company’s consolidation policy, see Note 1 on page 72.

Note 23 — Estimated Fair Value of Financial Instruments

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 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. Accordingly, the estimates provided herein do not necessarily indicate amounts which could be realized in a current exchange. Furthermore, as the Corporation typically holds the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed. The disclosures also do not include estimated fair value amounts for items which 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 Corporation used the following methods and assumptions in estimating fair value disclosures for financial instruments:

Cash and due from banks, federal funds sold and securities purchased under agreements to resell, and interest-bearing deposits with banks:  The carrying amount approximates the estimated fair value of these instruments.

Trading securities:  These securities are carried at quoted market value or the market value for comparable securities, which represents estimated fair value.

Loans held-for-sale:  The market value of these loans represents estimated fair value or estimated net selling price. The market value is determined on the basis of existing forward commitments or the current market values of similar loans.

Investment securities:  Investment securities are carried at quoted market value, if available. The market value for comparable securities is used to estimate fair value if quoted market values are not available.

Domestic business loans:  These consist of commercial, real estate construction, commercial mortgage and equipment lease financing loans. The estimated fair value of the Corporation’s variable rate commercial loans is represented by their carrying value, adjusted by an amount which estimates the change in fair value caused by changes in the credit quality of borrowers since the loans were originated. The estimated fair value of fixed rate commercial loans is calculated using a discounted cash flow model. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.

International loans:  These consist primarily of short-term trade-related loans, variable rate loans or loans which have no cross-border risk due to the existence of domestic guarantors or liquid collateral. The estimated fair value of the Corporation’s international loan portfolio is represented by their carrying value, adjusted by an amount which estimates the effect on fair value of changes in the credit quality of borrowers or guarantors.

Retail loans:  This category consists of residential mortgage, home equity and other consumer loans. The estimated fair value of residential mortgage loans is based on discounted contractual cash flows adjusted for expected prepayments. For home equity and other consumer loans, the estimated fair values are calculated using a discounted cash flow model. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.

Customers’ liability on acceptances outstanding and acceptances outstanding:  The carrying amount approximates the estimated fair value.

116

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

Loan servicing rights:  The estimated fair value is representative of a discounted cash flow analysis, using interest rates and prepayment speed assumptions currently quoted for comparable instruments.

Deposit liabilities:  The estimated fair value of demand deposits, consisting of checking, savings and certain money market deposit accounts, is represented by the amounts payable on demand. The carrying amount of deposits in foreign offices approximates their estimated fair value, while the estimated fair value of term deposits is calculated by discounting the scheduled cash flows using the year-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 estimated fair value.

Medium- and long-term debt:  The estimated fair value of the Corporation’s variable rate medium- and long-term debt is represented by its carrying value. The estimated fair value of the 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.

Derivative instruments:  The estimated fair value of interest rate and energy commodity swaps represents the amount the Corporation would receive or pay to terminate or otherwise settle the contracts at the balance sheet date, taking into consideration current unrealized gains and losses on open contracts. The estimated fair value of foreign exchange futures and forward contracts and commitments to purchase or sell financial instruments is based on quoted market prices. The estimated fair value of interest rate, energy commodity and foreign currency options (including caps, floors and collars) is determined using option pricing models. The estimated fair value of warrants that are accounted for as derivatives are valued using a Black-Scholes valuation model. All derivative instruments are carried at fair value on the balance sheet.

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 entered into. This estimate of fair value does not take into account the significant value of the customer relationships and the future earnings potential involved in such arrangements as the Corporation does not believe that it would be practicable to estimate a representational fair value for these items.

Note 24 — 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. 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 December 31, 2007. These methodologies, which are briefly summarized in the following paragraph, may be modified as management accounting systems are enhanced and changes occur in the organizational structure or product lines.

The Corporation’s internal funds transfer pricing system records cost of funds or credit for funds using a combination of matched maturity funding for certain assets and liabilities and a blended rate based on various maturities for the remaining assets and liabilities. The allowance for loan losses is allocated to both large business and certain large personal purpose consumer and residential mortgage loans that have deteriorated below certain levels of credit risk based on a non-standard, specifically calculated amount. Additional loan loss reserves are allocated based on industry-specific risk and are maintained to capture probable losses due to the inherent imprecision in the risk rating system and new business migration risk not captured in the credit scores of individual loans. For other business loans, the allowance for loan losses is recorded in business units based on the credit score of each loan outstanding. For other consumer and residential mortgage loans, it is allocated based on applying estimated loss ratios to various segments of the loan portfolio. The related loan loss provision is assigned based on the amount necessary to maintain an allowance for loan losses adequate for each product category. Noninterest income and expenses directly attributable to a line of business are assigned to that business segment. Direct expenses incurred by areas whose services support the overall Corporation are allocated to the business segments as follows: product processing expenditures are allocated based on standard unit costs applied to actual volume measurements; administrative expenses are allocated based on estimated time expended; and 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. Equity is attributed based on credit, operational and interest rate risks. Most of the equity attributed relates to credit risk, which is determined based on the credit score and expected remaining life of each loan, letter of credit and unused commitment recorded in the business units. Operational risk is allocated based on deposit balances, non-earning assets, trust assets under management, and the nature and extent of expenses incurred by business units. Virtually all interest rate risk is assigned to Finance, as are the Corporation’s hedging activities.

The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting 2007 performance can be found in the section entitled “Business Segments” in the financial review on page 33.

The Business Bank is primarily comprised of the following businesses: middle market, commercial real estate, national dealer services, international finance, global corporate, leasing, financial services, and technology and life sciences. This business segment meets the needs of medium-size businesses, multinational corporations and governmental entities by offering various products and services, including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.

The Retail Bank includes small business banking and personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. In addition to a full range of financial

119

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries

services provided to small business customers, this business segment offers a variety of consumer products, including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans.

Wealth & Institutional Management offers products and services consisting of fiduciary services, private banking, retirement services, investment management and advisory services, investment banking and discount securities brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.

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.

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 SFAS 131, “Disclosures about Segments of an Enterprise and Related Information,” (SFAS 131). The following discussion provides information about the activities of each market segment. A discussion of the financial results and the factors impacting 2007 performance can be found in the section entitled “Geographic Market Segments” in the financial review on page 34.

The Midwest market consists of operations located in the states of Michigan, Ohio and Illinois. Currently, Michigan operations represent the significant majority of this geographic market.

The Western market consists of 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 include businesses with a national perspective, the Corporation’s investment management and trust alliance businesses as well as activities in 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 and secondarily to international operations of 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.

The Corporation’s total revenues from customers and long-lived assets (excluding certain intangible assets) located in foreign countries in which the Corporation holds assets were less than five percent of the Corporation’s consolidated revenues and long-lived assets (excluding certain intangible assets) in each of the years ended December 31, 2007, 2006 and 2005.

Note 26 — Sales of Businesses/Discontinued Operations

In December 2006, the Corporation sold its ownership interest in Munder to an investor group. The sale, including associated costs and assigned goodwill, resulted in a net after-tax gain of $108 million, or $0.67 per average annual diluted share, in 2006. The sale agreement included an interest-bearing contingent note with an initial principal amount of $70 million, which will be realized if the Corporation’s client-related revenues earned by Munder remain consistent with 2006 levels of approximately $17 million per year for the five years following

the closing of the transaction(2007-2011). The principal amount of the note may be increased to a maximum of $80 million or decreased to as low as zero, depending on the level of such revenues earned in the five years following the closing. Repayment of the principal is scheduled to begin after the sixth anniversary of the closing of the transaction from Munder’s excess cash flows, as defined in the sale agreement. The note matures in December 2013. Future gains related to the contingent note are expected to be recognized periodically as targets for the Corporation’s client-related revenues earned by Munder are achieved. Recognition of the potential gains related to the contingent note will begin when cumulative client-related revenues exceed approximately $26 million, $18 million of which accumulated in 2007. The potential future gains are expected to be recorded between 2008 and the fourth quarter of 2011, unless fully earned prior to that time.

As a result of the sale transaction, the Corporation reported Munder as a discontinued operation in all periods presented. 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 income from discontinued operations recorded in 2007 reflected adjustments to the initial gain recorded at the closing of the Munder sale transaction. The components of net income from discontinued operations for the years ended December 31, 2007, 2006 and 2005, respectively, were as follows:

REPORT OF MANAGEMENT

The management of Comerica Incorporated (the Corporation) is responsible for the accompanying consolidated financial statements and all other financial information in this Annual Report. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles and include amounts which of necessity are based on management’s best estimates and judgments and give due consideration to materiality. The other financial information herein is consistent with that in the consolidated financial statements.

In meeting its responsibility for the reliability of the consolidated financial statements, management develops and maintains effective internal controls, including those over financial reporting, as defined in the Securities and Exchange Act of 1934, as amended. The Corporation’s internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles, and that receipts and expenditures of the Corporation are made only in accordance with authorizations of management and directors of the Corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Corporation’s assets that could have a material effect on the consolidated financial statements.

Management assessed, with participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, internal control over financial reporting as it relates to the Corporation’s consolidated financial statements presented in conformity with U.S. generally accepted accounting principles as of December 31, 2007. The assessment was based on criteria for effective internal control over financial reporting described in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management determined that internal control over financial reporting is effective as it relates to the Corporation’s consolidated financial statements presented in conformity with U.S. generally accepted accounting principles as of December 31, 2007.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The consolidated financial statements as of December 31, 2007 were audited by Ernst & Young LLP, an independent registered public accounting firm. The audit was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), which required the independent public accountants to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting is maintained in all material respects.

The Corporation’s Board of Directors oversees management’s internal control over financial reporting and financial reporting responsibilities through its Audit Committee as well as various other committees. The Audit Committee, which consists of directors who are not officers or employees of the Corporation, meets regularly with management, internal audit and the independent public accountants to assure that the Audit Committee, management, internal auditors and the independent public accountants are carrying out their responsibilities, and to review auditing, internal control and financial reporting matters.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Comerica Incorporated

We have audited Comerica Incorporated’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Comerica Incorporated’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Report of Management. Our responsibility is to express an opinion on the Corporation’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Corporation are being made only in accordance with authorizations of management and directors of the Corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Corporation’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Comerica Incorporated maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2007 consolidated financial statements of Comerica Incorporated and subsidiaries and our report dated February 20, 2008 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

Comerica Incorporated

We have audited the accompanying consolidated balance sheets of Comerica Incorporated and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Comerica Incorporated and subsidiaries at December 31, 2007 and 2006, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, in conformity with U.S. generally accepted accounting principles.

As discussed in Note 16 to the consolidated financial statements, in 2006 Comerica Incorporated and subsidiaries changed its method of accounting for pension and other postretirement plans.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Comerica Incorporated’s internal control over financial reporting as of December 31, 2007, based on criteria established in “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 20, 2008, expressed an unqualified opinion thereon.
