Executive Vice President and General Auditor David E. Duprey has been named chief financial officer of Comerica, effective immediately.

Duprey succeeds Karen L. Parkhill, vice chairman and chief financial officer, who is leaving to pursue other opportunities.

Duprey joined Comerica in 2006 from Ernst & Young (EY), where he served as a partner. During his time at EY, Duprey worked with Comerica and large regional and other financial institutions, along with retail and manufacturing companies in domestic and international venues.

Duprey joined EY in 1980 and was involved in numerous complex restructuring engagements and expense control initiatives. He also has experience executing strategies to assess clients’ business performance, and in complex audit and accounting, financial reporting and SEC matters.

“Dave has been a trusted advisor and an invaluable member of Comerica’s management team for a decade and is ideally suited for his new role as chief financial officer,” said Ralph W. Babb Jr., chairman and chief executive officer. “Dave will play an important role in driving the future of Comerica and creating value for our shareholders – especially in working with the Boston Consulting Group in its current review of our revenue and expense base.”

As chief financial officer, Duprey has direct management of Finance, overseeing Accounting, Business Finance, Investor Relations, Treasury and Economics, with responsibility for all financial reporting, and will report to Babb.

Christine Moore, who is currently Comerica’s senior vice president and deputy general auditor, will succeed Duprey as senior vice president and general auditor. Moore will report to the Audit Committee of the Comerica Incorporated board of directors.
