PART I

Item 1. Business

GENERAL

Comerica Incorporated (“Comerica” or the “Corporation”) is a multi-state financial services provider, incorporated under the laws of the State of Delaware, headquartered in Detroit, Michigan. Based on assets as of December 31, 2002, it was among the 20 largest banking companies in the United States and the largest bank holding company headquartered in Michigan in terms of both total assets and total deposits. Comerica was formed in 1973 to acquire the outstanding common stock of Comerica Bank (formerly Comerica Bank-Detroit), one of Michigan’s oldest banks (“Comerica Bank”). Since that time, Comerica has acquired financial institutions in California, Texas and Florida, and, in 1997, formed Comerica Bank-Mexico, S.A. and Comerica Bank-Canada. In 2001, Comerica established its Canadian branch and the assets and the majority of the liabilities of Comerica Bank-Canada were transferred to Comerica Bank’s Canadian branch. As of December 31, 2002, Comerica owned directly or indirectly all the outstanding common stock of five active banking and fifty-four non-banking subsidiaries. At December 31, 2002, Comerica had total assets of approximately $53 billion, total deposits of approximately $42 billion, total loans (net of unearned income) of approximately $42 billion and common shareholders’ equity of approximately $5 billion.

BUSINESS STRATEGY

Comerica has strategically aligned its operations into three major lines of business: the Business Bank, the Individual Bank and the Investment Bank. The Business Bank is comprised of middle market lending, asset-based lending, large corporate banking, international financial services and speciality businesses, including technology and life sciences, specialty deposit gathering and entertainment lending. This line of business 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 Individual Bank includes consumer lending, consumer deposit gathering, mortgage loan origination, small business banking (annual sales under $10 million) and private banking. This line of business offers a variety of consumer products, including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans. In addition, a full range of financial services is provided to small businesses and municipalities. Private lending and personal trust services are also provided to meet the personal financial needs of affluent individuals (as defined by individual net income or wealth).

The Investment Bank is responsible for institutional trust products, retirement services and provides investment management and advisory services (including Munder), investment banking and discount securities brokerage services. This line of business also offers the sale of mutual fund and annuity products, as well as life, disability and long-term care insurance products.

Comerica has positioned itself to deliver financial services in its four primary geographic markets: Michigan, California, Texas, and Florida, with operations in numerous other states, Canada and Mexico.

In addition to the three major lines of business, the Finance segment is also significant. The Finance segment includes Comerica’s securities portfolio and asset and liability management activities. This segment is responsible for managing Comerica’s funding, liquidity and capital needs, performing interest sensitivity gap and earnings simulation analysis and executing various strategies to manage Comerica’s exposure to liquidity and interest rate risks.

SUPERVISION AND REGULATION

Banks, bank holding companies and financial institutions are highly regulated at both the state and federal level. Comerica is subject to supervision and regulation by the Federal Reserve Board (“FRB”) under the Bank Holding Company Act of 1956, as amended (the “Act”).

The Gramm-Leach-Bliley Act of 1999 expanded the activities in which a bank holding company registered as a financial holding company can engage. The conditions to be a financial holding company, among others, include the requirement that each depository institution subsidiary of the holding company be well capitalized and well managed.

Comerica became a financial holding company in 2000. As a financial holding company, in addition to bank holding company powers, Comerica may affiliate with securities firms and insurance companies and engage in activities that are financial in nature. Activities that are “financial in nature” include, but are not limited to: securities underwriting; dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and agency; merchant banking; travel agent services; and activities that the FRB has determined to be closely related to banking. A bank holding company that is not also a financial holding company is limited to engaging in banking and other activities previously determined by the FRB to be closely related to banking.

Comerica Bank is chartered by the State of Michigan and is primarily supervised and regulated by the Division of Financial Institutions, Office of Financial and Insurance Services of the State of Michigan and the FRB. Comerica Bank-California is chartered by the State of California and is primarily supervised and regulated by the California Department of Financial Institutions and the FRB. Comerica Bank-Texas is chartered by the State of Texas and is primarily supervised and regulated by the Texas Department of Banking and the FRB. Comerica Bank & Trust, National Association is chartered under federal law and subject to supervision and regulation by the Office of the Comptroller of the Currency (“OCC”). Comerica Bank, Comerica Bank- California, Comerica Bank-Texas and Comerica Bank & Trust, National Association, are members of the Federal Reserve System (“FRS”). The deposits of all the foregoing banks are insured by the Bank Insurance Fund (“BIF”) of the Federal Deposit Insurance Corporation (“FDIC”) to the extent provided by law. Comerica Bank-Mexico, S.A. is chartered under the laws of Mexico and is supervised and regulated by the Ministry of Finance and Public Credit, the Bank of Mexico, and the Mexican National Banking Commission. Comerica Bank-Canada (which is in the winding up process, with active operations conducted by the Canadian branch) is chartered under the laws of Ontario, Canada and is supervised and regulated by the Office of the Superintendent of Financial Institutions Canada and the Canada Deposit Insurance Corporation.

4

The FRB supervises non-banking activities conducted by companies owned by Comerica Bank, Comerica Bank-California and Comerica Bank-Texas and the OCC supervises non-banking activities conducted by companies owned by Comerica Bank & Trust, National Association. In addition, Comerica’s non-banking subsidiaries are subject to supervision and regulation by various state, federal and self-regulatory agencies, including, but not limited to, the National Association of Securities Dealers, Inc. (in the case of Comerica Securities, Inc. and Comerica Capital Markets Corporation), the Department of Insurance of the State of Michigan (in the case of Comerica Insurance Services, Inc.), and the Securities and Exchange Commission (in the case of Munder Capital Management, the Corporation’s investment advisory subsidiary).

In most cases, no FRB approval is required for Comerica to acquire a company, other than a bank holding company or insured depository institution, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the FRB. Prior FRB approval is required before Comerica may acquire the beneficial ownership or control of more than 5% of the voting shares or substantially all of the assets of a bank holding company or bank. If any subsidiary bank of Comerica ceases to be “well capitalized” or “well managed” under applicable regulatory standards, the Federal Reserve Board may place limitations on the Corporation’s ability to conduct the broader financial activities permissible for financial holding companies or impose any limitations or conditions on the conduct or activities of the Corporation or any of its affiliates as the Federal Reserve Board finds appropriate and consistent with the purpose of the Bank Holding Company Act. If the deficiencies persist, the Federal Reserve Board may order Comerica to divest any subsidiary bank or cease to engage in any activities permissible for financial holding companies that are not permissible for bank holding companies. Alternatively, Comerica may elect to conform its non-banking activities to those permissible for a bank holding company that is not also a financial holding company. If any subsidiary bank of Comerica receives a rating under the Community Reinvestment Act of 1977 of less than satisfactory, Comerica will be prohibited from engaging in new activities not permissible for non-financial holding companies/bank holding companies or acquiring companies other than bank holding companies or banks.

Various governmental requirements, including Sections 23A and 23B of the Federal Reserve Act and Regulation W, limit borrowings by Comerica and its nonbank subsidiaries from its affiliate insured depository institutions, and also limit various other transactions between Comerica and its nonbank subsidiaries, on the one hand, and its affiliate insured depository institutions, on the other. For example, Section 23A of the Federal Reserve Act limits to no more than 10% of its total capital, the aggregate outstanding amount of any insured depository institution’s loans and other “covered transactions” with any particular nonbank affiliate, and limits to no more than 20% of its total capital, the aggregate outstanding amount of any insured depository institution’s covered transactions with all of its nonbank affiliates. Section 23A of the Federal Reserve Act also generally requires that an insured depository institution’s loans to its nonbank affiliates be secured, and Section 23B of the Federal Reserve Act generally requires that an insured depository institution’s transactions with its nonbank affiliates be on arms-length terms.

Set forth below are summaries of selected laws and regulations applicable to Comerica and its subsidiaries. The summaries are not complete and are qualified in their entirety by references to the particular statutes and regulations, and are not intended as legal advise that should be relied upon for any reason. A change in applicable law or regulation could have a material effect on the business of Comerica.

Interstate Banking and Branching

Pursuant to the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the “Interstate Act”), a bank holding company may acquire banks in states other than its home state, without regard to the permissibility of such acquisition under state law, but subject to any state requirement that the bank has been organized and operating for a minimum period of time, not to exceed five years, and the requirement that the bank holding company, prior to and following the proposed acquisition, control no more than ten percent of the total amount of deposits of insured depository institutions in the United States and no more than thirty percent of such deposits in that state (or such amount as established by state law if such amount is lower than thirty percent).

The Interstate Act also authorizes banks to acquire branch offices outside their home states by merging with out-of-state banks, purchasing branches in other states and establishing de novo branches in other states, thereby creating interstate branching; provided that in the case of purchasing branches and establishing new branches in a state in which it does not already have banking operations in such state, such state must have “opted-in” to the Act by enacting a law permitting such de novo branching and, in the case of mergers, such state must not have “opted- out” of that portion of the Act.

Since the provision permitting interstate bank acquisitions became effective, Comerica has had enhanced opportunities to acquire banks in any state, subject to approval by the appropriate federal and state regulatory agencies. Under the Interstate Act, Comerica has the opportunity to consolidate its affiliate banks to create one bank with branches in more than one state, or to establish branches in different states, subject to any state “opt-in” and “opt-out” provisions.

Dividends

Comerica is a legal entity separate and distinct from its banking and other subsidiaries. Most of Comerica’s revenues result from dividends its bank subsidiaries pay it. There are statutory and regulatory requirements applicable to the payment of dividends by subsidiary banks to Comerica as well as by Comerica to its shareholders. Certain, but not all, of these requirements are discussed below.

Each state bank subsidiary that is a member of the FRS and each national banking association is required by federal law to obtain the prior approval of the FRB or the OCC, as the case may be, for the declaration and payment of dividends, if the total of all dividends declared by the board of directors of such bank in any calendar year will exceed the total of (i) such bank’s retained net income (as

6

defined and interpreted by regulation) for that year plus (ii) the retained net income (as defined and interpreted by regulation) for the preceding two years, less any required transfers to surplus or to fund the retirement of preferred stock. Further, federal regulatory agencies can prohibit a banking institution or bank holding company from engaging in unsafe and unsound business practices and could prohibit the payment of dividends if such payment could be deemed an unsafe and unsound banking practice. In addition, Comerica’s state bank subsidiaries are also subject to limitations under state law regarding the amount of earnings that may be paid out as dividends, and require prior approval for payments of dividends that exceed certain levels.

At January 1, 2003, Comerica’s subsidiary banks, without obtaining prior governmental approvals, could declare aggregate dividends of approximately $101 million from retained net profits of the preceding two years, plus an amount approximately equal to the net profits (as measured under current regulations), if any, earned for the period from January 1, 2003 through the date of declaration. Comerica’s subsidiary banks paid dividends of $647 million in 2002, $578 million in 2001, and $339 million in 2000.

Source of Strength

According to Federal Reserve Board policy, bank holding companies are expected to act as a source of strength to each subsidiary bank and to commit resources to support each subsidiary bank. This support may be required at times when a bank holding company may not be able to provide such support. Similarly, under the cross-guarantee provisions of the Federal Deposit Insurance Act, in the event of a loss suffered or anticipated by the FDIC (either as a result of the default of a banking or thrift subsidiary or related to FDIC assistance provided to a subsidiary in danger of default) the other banking subsidiaries may be assessed for the FDIC’s loss, subject to certain exceptions.

FDICIA

The Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) requires, among other things, the federal banking agencies to take “prompt corrective action” in respect of depository institutions that do not meet minimum capital requirements. FDICIA establishes five capital tiers: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.” A depository institution’s capital tier will depend upon where its capital levels are in relation to various relevant capital measures, which, among others, include a Tier 1 and total risk-based capital measure and a leverage ratio capital measure, and certain other factors.

Regulations establishing the specific capital tiers provide that, for a depository institution to be well capitalized it must have a total risk-based capital ratio of at least 10 percent, a Tier 1 risk-based capital ratio of at least 6 percent, a Tier 1 leverage ratio of at least 5 percent and not be subject to any specific capital order or directive. For an institution to be adequately capitalized it must have a total risk-based capital ratio of at least 8 percent, a Tier 1 risk-based capital ratio of at least 4 percent and a Tier 1

7

leverage ratio of at least 4 percent (and in some cases 3 percent). Under certain circumstances, the appropriate banking agency may treat a well capitalized, adequately capitalized or undercapitalized institution as if the institution were in the next lower capital category. As of December 31, 2002, each of the banking subsidiaries of Comerica were well capitalized under these regulations.

FDICIA generally prohibits a depository institution from making any capital distribution (including payment of a dividend) or paying any management fee to its holding company if the depository institution would thereafter be undercapitalized. Undercapitalized depository institutions are subject to limitations on growth and certain activities and are required to submit an acceptable capital restoration plan. The federal banking agencies may not accept a capital plan without determining, among other things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution’s capital. In addition, for a capital restoration plan to be acceptable, the depository institution’s parent holding company must guarantee for a specific time period that the institution will comply with such capital restoration plan. The aggregate liability of the parent holding company under the guaranty is limited to the lesser of (i) an amount equal to 5 percent of the depository institution’s total assets at the time it became undercapitalized, or (ii) the amount that is necessary (or would have been necessary) to bring the institution into compliance with all capital standards applicable with respect to such institution as of the time it fails to comply with the plan. If a depository institution fails to submit or implement an acceptable plan, it is treated as if it is significantly undercapitalized.

Significantly undercapitalized depository institutions are subject to a number of requirements and restrictions. Specifically, such a depository institution may be required to do one or more of the following, among other things: sell sufficient voting stock to become adequately capitalized, reduce the interest rates it pays on deposits, reduce its rate of asset growth, dismiss certain senior executive officers or directors, and stop accepting deposits from correspondent banks. Critically undercapitalized institutions are subject to the appointment of a receiver or conservator or such other action as the FDIC and the applicable federal banking agency shall determine appropriate.

FDICIA also contains a variety of other provisions that may affect the operations of depository institutions including reporting requirements, regulatory standards for real estate lending, “truth in savings” provisions, the requirement that a depository institution give 90 days prior notice to customers and regulatory authorities before closing any branch and a prohibition on the acceptance or renewal of brokered deposits by depository institutions that are not well capitalized or are adequately capitalized and have not received a waiver from the FDIC. Comerica’s United States subsidiary banks are all well-capitalized and may accept brokered deposits.

Capital Requirements

The FRB imposes, on Comerica, risk-based capital requirements and guidelines, which are substantially similar to the capital requirements and guidelines imposed by the OCC and the FDIC on depository institutions under their jurisdictions.

For this purpose, a depository institution’s or holding company’s assets and certain specified off- balance sheet commitments are assigned to four risk categories, each weighted differently based on the level of credit risk that is ascribed to such assets or commitments. A depository institution’s or holding company’s capital, in turn, is divided into two tiers: core (“Tier 1”) capital, which includes common equity, non-cumulative perpetual preferred stock and a limited amount of cumulative perpetual preferred stock and related surplus (excluding auction rate issues) and a limited amount of cumulative perpetual stock and minority interests in equity accounts of consolidated subsidiaries, less goodwill, certain identifiable intangible assets and certain other assets; and supplementary (“Tier 2”) capital, which includes, among other items, perpetual preferred stock not meeting the Tier 1 definition, mandatory convertible securities, subordinated debt and allowances for loan and lease losses, subject to certain limitations, less certain required deductions.

The Corporation, like other bank holding companies, currently is required to maintain Tier 1 and “total capital” (the sum of Tier 1 and Tier 2 capital) equal to at least 4% and 8% of its total risk- weighted assets (including certain off-balance-sheet items, such as standby letters of credit), respectively. At December 31, 2002, the Corporation met both requirements, with Tier 1 and total capital equal to 8.05% and 11.72% of its total risk-weighted assets.

The FRB, FDIC and OCC rules require Comerica to incorporate market and interest rate risk components into their risk-based capital standards. Under the market risk requirements, capital is allocated to support the amount of market risk related to a financial institution’s ongoing trading activities. The FRB also requires bank holding companies to maintain a minimum “leverage ratio” (Tier 1 capital to adjusted total assets) of 3% if the holding company has the highest regulatory rating and meets certain other requirements, or of 3% plus an additional cushion of at least 100 to 200 basis points if the holding company does not meet these requirements. At December 31, 2002, the Corporation’s leverage ratio was 9.29%.

As an additional means to identify problems in the financial management of depository institutions, FDICIA requires federal bank regulatory agencies to establish certain non-capital safety and soundness standards for institutions they supervise. The standards relate generally to, among others, earnings, liquidity, operations and management, asset quality, various risk and management exposures (e.g. credit, operational, market, interest rate, etc.) and executive compensation. The agencies are authorized to take action against institutions that fail to meet such standards.

FDIC Insurance Assessments

Comerica’s subsidiary banks are subject to FDIC deposit insurance assessments to maintain the Bank

9

Insurance Fund (the “BIF”) and the Savings Insurance Fund (the “SAIF”). As of December 31, 2002, the Corporation’s banking subsidiaries held approximately $39.7 billion and $1.1 billion, respectively, of BIF- and SAIF- assessable deposits. The Corporation currently pays no deposit insurance assessments on these deposits under the FDIC’s risk related assessment system, but could be required to pay insurance assessments in 2003.

Enforcement Powers of Federal Banking Agencies

The FRB and other federal banking agencies have broad enforcement powers, including the power to terminate deposit insurance, impose substantial fines and other civil and criminal penalties and appoint a conservator or receiver. Failure to comply with applicable laws, regulations and supervisory agreements could subject Comerica or its banking subsidiaries, as well as officers and directors of these organizations, to administrative sanctions and potentially substantial civil penalties.

Future Legislation

Changes to the laws of the states and countries in which the Corporation and its subsidiaries do business can affect the operating environment of bank holding companies and their subsidiaries in substantial and unpredictable ways. Comerica cannot accurately predict whether such changes will occur or, if they occur, the ultimate effect they would have upon the financial condition or results of operations of the Corporation.

COMPETITION

Financial service provision is a highly competitive business. The Michigan banking subsidiary of the Corporation competes primarily with banks based in the Midwest region of the United States for loans, deposits and trust accounts. Through its offices in Arizona, Colorado, Georgia, Illinois, Indiana, Louisiana, Massachusetts, Minnesota, North Carolina, New Jersey, Nevada, New York, Ohio, Oregon, Pennsylvania, Tennessee, Virginia and Washington, Comerica competes with other financial institutions for various deposits, loans and other products and services.

At year-end 2002, Comerica was the largest financial holding company headquartered in Michigan in terms of total assets and deposits. Based on the Interstate Act as described above and the Gramm-Leach Bliley Act, Comerica believes that the level of competition in all geographic markets will increase in the future. Comerica’s banking subsidiaries also face competition from other financial intermediaries, including savings and loan associations, consumer finance companies, leasing companies, credit unions, banks, insurance companies and securities firms.

EMPLOYEES

As of December 31, 2002, Comerica and its subsidiaries had 10,368 full-time and 1,440 part-time employees.

Item 3. Legal Proceedings

The Corporation and certain of its subsidiaries are subject to various pending and threatened legal proceedings, including certain purported class actions, 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 any such matters will be; however, based on current knowledge and after consultation with legal counsel, management does not believe that the amount of any resulting liability arising from these matters will have a material adverse effect on the Corporation’s consolidated financial position or results from operations.

Item 4. Submission of Matters to a Vote of Security Holders

The Corporation did not submit any matters for a shareholders’ vote in the fourth quarter of 2002.

Amended and Restated Comerica Incorporated Stock Option Plan for Non-employee Directors of Comerica Bank and Affiliated Banks — Under this Plan, the Corporation may grant options to acquire up to 450,000 shares of Common Stock, subject to equitable adjustment upon the occurrence of events such as stock splits, stock dividends or recapitalizations. After each annual meeting of shareholders, each member of the Board of Directors of a subsidiary bank of the Corporation who is not an employee of the Corporation or of any of its subsidiaries will be automatically granted an option to purchase 2,000 shares of the common stock of the Corporation. Option grants under the Plan are in addition to annual retainers, meeting fees and other compensation payable to non-employee directors in connection with their services as directors. The Plan is administered by a committee of the Board of Directors. With respect to the automatic grants, the Committee does not have discretion with respect to matters such as the selection of directors to whom options will be granted, the timing of grants, the number of shares to become subject to each option grant, the exercise price of options, or the periods of time during which any option may be exercised. In addition to the automatic grants, the Committee may grant options to the non-employee directors in its discretion. The exercise price of each option granted is the fair market value of each share of common stock subject to the option on the date the option is granted. The exercise price is payable in full upon exercise of the option and may be paid in cash or by delivery of previously owned shares. The Committee may change the option price per share following a corporate reorganization or recapitalization so that the aggregate option price for all shares subject to each outstanding option prior to the change is equivalent to the aggregate option price for all shares or other securities into which option shares have been converted or which have been substituted for option shares. The term of each option cannot be more than ten years.

Three-Year Incentive Plan — The Corporation grants cash awards to its eligible employees in accordance with the terms of its incentive plans based on performance of the Corporation over specified three year periods. The Corporation pays the award to each of the executive officers in cash and fifty percent of the award automatically is invested in shares of non-transferable common stock. If

15

the participant defers the award, one hundred percent of deferred awards are deemed invested in Comerica common stock and are paid out in common stock. Executives may not transfer stock awarded through this program until the executive’s employment with Comerica terminates.

Employee Service Award Program — This program provides a method to recognize and reward employees for attaining specified years of service. From 1993 to December 31, 2002, the Corporation issued 49,509 shares of Common Stock under this program. Each year, the Corporation authorizes the awards of shares to employees who attain the requisite years of service. Currently under the program employees receive 4, 5, 7 and 10 shares of common stock for attaining ten, fifteen, twenty and twenty-five years of service, respectively. The number of shares awarded each year depends on the employees who attain the requisite years of service. For the year to date 2003, the Corporation has issued 695 shares of Common Stock under this program.

Employee Stock Purchase Plan — Under the Corporation’s Employee Stock Purchase Plan (the “ESPP”), a total of 1.4 million shares of the Corporation’s common stock have been registered for sale to eligible Corporation employees. Under the ESPP, participating employees have a convenient and affordable way to purchase shares of Comerica Incorporated common stock, through after-tax payroll deductions without being charged a brokerage fee. The Corporation provides a 15 percent quarterly match and a 5 percent retention match on shares of Common Stock held by the participants in the plan for two years. Matches are not made on employee contributions over $25,000 per year. Under the ESPP, the Corporation common stock is generally purchased in the open market by the ESPP plan administrator as soon as practicable under the plan.

Directors Deferred Compensation Plans — The Corporation maintains two deferred compensation plans for non-employee directors of the Corporation and its subsidiaries, the Common Stock Deferral Plan and the Director Fee Deferral Plan. The Common Stock Deferral Plan provides for the mandatory deferral of 50% of the annual retainer of each director of the Corporation into shares of common stock of the Corporation. Such directors voluntarily may defer the remaining 50% of their director fees and all other non-employee directors of the Corporation’s subsidiaries may choose to defer up to 100% of their director fees into the Common Stock Deferral Plan or into the Director Fee Deferral Plan which permits non- corporation stock investments, or a combination of the two plans. The directors’ accounts under the plans are increased in connection with the payment of dividends or other distributions paid on the Corporation common stock to reflect the number of additional shares of Corporation common stock that could have been purchased had the dividends or other distributions been paid on each share of common stock underlying then outstanding stock units in the directors’ accounts. Common Stock units are payable following termination of service as a director out of shares of the Corporation’s common stock held in the plan.

16

1999 Deferred Compensation Plan — The Corporation maintains a Deferred Compensation Plan for its eligible employees of the Corporation and its subsidiaries. The employees may voluntarily defer specified portions of their salary and bonus into shares of common stock of the Corporation. The employees’ accounts under the plan are increased in connection with the payment of dividends or other distributions paid on the Corporation’s common stock to reflect the number of additional shares of the Corporation’s common stock that could have been purchased had the dividends or other distributions been paid on each share of common stock underlying then outstanding stock units in the employees’ accounts. The deferred compensation is payable following termination of service as an employee out of shares of the Corporation’s common stock held in the plan.

FORWARD-LOOKING STATEMENTS

This Report contains statements that are considered “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. In addition, the Corporation may make other written and oral communications from time to time that contain such statements. Forward- looking statements, including statements as to industry trends, future expectations of the Corporation and other matters that do not relate strictly to historical facts, are based on certain assumptions by management. Forward-looking statements are often identified by words or phrases such as “anticipate,” “believe,” “expect,” “intend,” “seek,” “plan,” “objective,” “seek,” “trend” and “goal.” Forward-looking statements are subject to various assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date they are made, and the Corporation undertakes no obligation to update any forward-looking statements. Actual results could differ materially from those anticipated in forward-looking statements and future results could differ materially from historical performance.

In addition to factors mentioned elsewhere in this report or previously disclosed in the Corporation’s SEC reports (accessible on the SEC’s website at www.sec.gov or on the Corporation’s website at www.comerica.com), the following factors, among others, could cause actual results to differ materially from forward-looking statements and future results could differ materially form historical performance:

• general political and economic conditions, either domestically or internationally, may be less favorable that expected;

• Latin America may continue to experience economic, political and social uncertainties;

• developments concerning credit quality in various industry sectors may result in an increase in the level of the Corporation’s provision for credit losses, nonperforming assets, net charge-offs and reserve for credit losses;

20

• domestic demand for commercial loan and investment advisory products may continue to be weak;

• customer borrowing, repayment, investment and deposit practices generally may be less favorable than anticipated;

• interest rate and currency fluctuations, equity and bond market fluctuations, and inflation may be greater than expected;

• the mix of interest rates and maturities of the Corporation’s interest earning assets and interest bearing liabilities (primarily loans and deposits) may be less favorable than expected;

• global capital markets in general, and the technology industry in particular, may continue to exhibit weakness, adversely affecting the Corporation’s investment advisory business line, as well as the Corporation’s private banking and brokerage business lines, and the availability and terms of funding necessary to meet the Corporation’s liquidity needs;

• the introductions, withdrawal, success and timing of business initiatives and strategies;

• competitive product and pricing pressures among financial institutions within the Corporation’s markets may increase;

• legislative or regulatory developments, including changes in laws or regulations concerning taxes, banking, securities, capital requirements and risk-based capital guidelines, reserve methodologies, deposit insurance and other aspects of the financial services industry, may adversely affect the business in which the Corporation is engaged or the Corporation’s financial results;

• legal and regulatory proceedings and related matters with respect to the financial services industry, including those directly involving the Corporation and its subsidiaries, could adversely affect the Corporation or the financial services industry generally;

• pending and proposed changes in accounting rules, policies, practices and procedures could adversely affect the Corporation’s financial results;

• instruments and strategies used to hedge or otherwise manage exposure to various types of market and credit risk could be less effective than anticipated, and the Corporation may not be able to effectively mitigate its risk exposures in particular market environments or against

21

	particular types of risk;
•	terrorist activities or other hostilities, which may adversely affect the general economy, financial and capital markets, specific industries, and the Corporation; and
•	technological changes, including the impact of the internet on the Corporation’s businesses, may be more difficult or expensive than anticipated.
