These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the 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, information regarding the Plan's assets available for benefits at December 30, 2002 and 2001 and the changes therein for the year ended December 30, 2002, in conformity with accounting principles generally accepted in the United States. Our audits were made for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedules of assets (held at end of year) as of December 30, 2002 and reportable transactions for the year then ended, are presented for purposes of additional analysis and are not a required part of the financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, are fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young LLP Detroit, Michigan May 30, 2003 1 Comerica Incorporated Preferred Savings Plan Statements of Assets Available for Benefits DECEMBER 30 2002 2001 ------------------------------------------- ASSETS Investments, at fair value: Mutual and money market funds $ 122,110,720 $ 218,478,446 Collective trust funds 167,015,973 72,956,768 Comerica Incorporated common stock 194,380,609 270,243,519 Participant loans 19,005,399 17,747,304 Corporate stocks - 301,494 ------------------------------------------- Total investments 502,512,701 579,727,531 Accrued income 2,568,172 2,410,107 Contribution receivable 2,066,000 8,264,000 ------------------------------------------- Total assets $ 507,146,873 $ 590,401,638 =========================================== See accompanying notes. 2 Comerica Incorporated Preferred Savings Plan Statement of Changes in Net Assets Available for Benefits Year Ended December 30, 2002 ADDITIONS Participant contributions $ 45,416,657 Employer contributions 8,429,449 Interest and dividend income 16,967,911 ----------------- Total additions 70,814,017 DEDUCTIONS Distributions to participants 36,469,052 Loan fees 103,719 ----------------- Total deductions 36,572,771 Net depreciation in fair value of investments (117,496,011) ----------------- Net decrease (83,254,765) Assets available for benefits: Beginning of year 590,401,638 ----------------- End of year $ 507,146,873 ================= See accompanying notes. 3 Comerica Incorporated Preferred Savings Plan Notes to Financial Statements December 30, 2002 and 2001 and Year Ended December 30, 2002 1. DESCRIPTION OF THE PLAN The Comerica Incorporated Preferred Savings Plan (the "Plan") is a defined contribution plan covering all eligible employees of Comerica Incorporated (the "Corporation") and certain subsidiaries. On January 29, 2001, the Corporation acquired Imperial Bancorp. As a result, the assets from the Employee Stock Ownership Plan of Imperial Bancorp and the Salary Investment Plan of Imperial Bancorp transferred to the Plan on August 31, 2001 and September 17, 2001, respectively. Participants in the Imperial Bancorp Plans became eligible to contribute to the Plan as of July 1, 2001. Information about the Plan agreement, participants' investment alternatives and the vesting and benefit provisions is contained in the pamphlet "Comerica Incorporated Preferred Savings Plan." Copies of this pamphlet are available from the Corporation's Human Resources Office. Participants may make annual contributions to the Plan on a pre-tax basis, not to exceed the lesser of 50% and 20% in 2002 and 2001, respectively, of the participant's annual compensation or the IRS allowed maximum ($11,000, plus an additional $1,000 for participants over 50 years of age, in 2002 and $10,500 in 2001). The Corporation will match a percentage of the first $3,000 of the participant's pre-tax contributions, as defined by the Plan. In addition, the Corporation may make discretionary contributions based upon attaining certain corporate financial performance measurements. Both the Corporation match and discretionary contribution are invested in the Corporation's common stock. During 1999, the Plan was amended to add an Employee Stock Ownership Plan ("ESOP") provision to the Plan. Participants' investments in the Corporation's common stock, including vested corporate matching contributions, are held in an ESOP account and dividends earned on the stock are paid outside the Plan. Participants may elect to either reinvest the dividends in the Corporation's common stock within the Plan or receive the dividends as cash with their regular pay. Contributions receivable represent amounts due from the Corporation under a performance match program, which rewards employees through a corporate contribution to the participants' accounts. 4 Comerica Incorporated Preferred Savings Plan Notes to Financial Statements (continued) December 30, 2002 and 2001 and Year Ended December 30, 2002 1. DESCRIPTION OF THE PLAN (CONTINUED) Participants direct the investment of their accounts, except the nonparticipant directed investment in the Corporation's common stock, among the investment funds offered by the Plan. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. Prior to the 2002 plan year, all employer matches and employer contributions were made in Comerica Incorporated common stock and permanently held in a restricted Comerica Incorporated common stock account. At the beginning of plan year 2002, the Plan was changed to provide that these employer matches and employer contributions are to be held in a restricted Comerica Incorporated common stock account until the end of the calendar year, when the assets held in such account become vested and unrestricted and, therefore, eligible to be reallocated to other fund options. Approximately $73.3 million of restricted common stock was transferred to unrestricted funds during the plan year ended December 30, 2002. The Corporation has the right to amend or terminate the Plan at any time. In the event the Plan is terminated, all participants' accounts become fully vested and nonforfeitable. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The fair values of the participation units owned by the Plan in mutual and collective trust funds are based on the net asset values on the last business day of the plan year. Marketable securities are stated at fair value. Securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the plan year. Investments traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and ask prices. The fair value of investments in the Corporation's common stock is based on the last reported sales price on the last business day of the plan year as traded on the New York Stock Exchange. The participant loans are valued at their outstanding balances, which approximate fair value. Administrative expenses incurred in connection with the operation of the Plan are borne by the Corporation, except for a $10 per quarter loan fee paid by participants. 5 Comerica Incorporated Preferred Savings Plan Notes to Financial Statements (continued) December 30, 2002 and 2001 and Year Ended December 30, 2002 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. 3. INVESTMENTS The fair value of individual investments that represent 5% or more of the Plan assets at the end of the respective years are as follows: DECEMBER 30 2002 2001 -------------------------------------- Comerica S&P 500 Index Fund $ 78,030,248 $ * Munder Multi-Season Growth Fund * 39,428,045 Munder Institutional S&P 500 Index Equity Fund * 69,302,342 Comerica Investment Contract Fund 88,985,725 72,956,768 Comerica Incorporated common stock 194,380,609 270,243,519 * Less than 5%.

TAX STATUS The Plan has received determination letters from the Internal Revenue Service dated June 29, 1998 and December 1, 1998, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to the issuance of these determination letters, new provisions in the Code were made and the Plan was amended accordingly. The Plan has applied for but has not received a new determination letter from the Internal Revenue Service stating the Plan is qualified under the provisions of the Code. However, the plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax exempt. 7. DIFFERENCES BETWEEN FINANCIAL STATEMENTS AND FORM 5500 Amounts allocated to withdrawn participants are recorded on the Form 5500 for benefit claims that have been processed and approved for payment prior to year-end but not yet paid.
