DETROIT/ December 2, 2003 -- Comerica Incorporated (NYSE: CMA) today announced a partnership with SmartMoney Custom Solutions that will enhance the bank's Internet offerings by providing expanded services and information for their Retirement Services clients and their participants.

Through the partnership, all visitors to Comerica's Web site have access to an online retirement center, with content and interactive tools from the popular Web site, SmartMoney.com . In addition to retirement planning resources, financial calculators, regularly updated articles and a financial glossary, the site at www.comerica.com/retirementcenter includes numerous interactive worksheets for IRAs, asset-allocation, stock, bond, mutual fund investing and more. The section titled "Retirement Accounts at Work," designed specifically for Comerica's defined contribution clients and participants, is loaded with useful information and can assist users in answering the much asked retirement questions: "How much should I save?" "How much should I invest?" and "How long will my money last?"

In addition, individuals who have retirement plans administered by Comerica can now obtain detailed information online about the funds offered in their plan. This information allows participants to easily review and compare all the funds available in their plans. To further assist customers with retirement planning, participants in plans administered by Comerica now receive their personal rate of return. The personal rate of return calculation is the participant's customized rate of return that accounts for all activity in their retirement account. This enhancement will help participants in Comerica's Retirement Services plans know the performance of their personal portfolio in addition to the performance of their fund offerings.

"Our goal is to provide investors at all levels with educational tools and content that will make achieving their goals and managing their investments easier," said Kathleen Zenisek, Vice President and Managing Director of Product Management, Comerica Retirement Services. "Our new enhancements and partnership with SmartMoney is consistent with Comerica's strategy of focusing on relationships, and helping businesses and people be successful."

Andrew Seibert, General Manager and Editorial Director of SmartMoney Custom Solutions commented, "As a retirement plan provider, Comerica is stepping up to the plate and enhancing the participant experience. We're delighted to support their efforts in a dynamic format."
