Comerica subsidiary to sell Framlington Investment Management

DETROIT, July 28, 2005 — Munder Capital Management, a subsidiary of Comerica Incorporated, today announced that Framlington Holdings Limited, which is 49 percent owned by Munder’s United Kingdom subsidiary, Munder UK, L.L.C., and 51 percent indirectly owned by HSBC Holdings plc, has reached an agreement to sell its 90.8 percent interest in London-based Framlington Group Limited to AXA Investment Managers.

AXA will pay approximately $342.5 million in cash (196.3 million pounds) for the entire interest of Framlington Group. Subject to market effects, Comerica’s after tax gain is expected to be in the range of $25 million to $30 million.

Munder, which acquired its stake in Framlington in October 1996, said the divestiture is consistent with its enhanced focus on domestic asset management.

The sale requires approval from the Financial Services Authority, a United Kingdom regulatory agency. The sale is expected to close in the fourth quarter of 2005.
