DETROIT, May 21, 2002 /PRNewswire-FirstCall via COMTEX/ -- In response to a
U.S. bank regulatory directive to banks with Argentine exposure, Comerica
Incorporated (NYSE: CMA) today announced that it will provide reserves for
Argentine transfer risk. Transfer risk is the risk that Argentine borrowers will
not be able to exchange pesos for U.S. dollars in order to pay their debts to
U.S. banks when due. Comerica will include an incremental charge in the second
quarter 2002 of up to $63 million ($41 million after-tax, or $0.23 cents per
share). Of the potential $63 million, $53 million would be recorded as a
provision for credit losses, with the remainder recorded as a securities loss to
write down the book value of Argentine securities exposure.

(Logo: http://www.newscom.com/cgi-bin/prnh/20010807/CMALOGO ) Comerica's total
exposure to Argentina is $141 million, which consists of $96 million of loans,
$26 million of securities and $19 million of unfunded commitments. This exposure
is down from $156 million at March 31, 2002, and from $219 million at December
31, 2001. Comerica currently has $5 million of Argentine loans in nonperforming
assets.

"The economic and political environment in Argentina is very difficult, and we
continue to monitor the situation closely and reduce our position," said Ralph
W. Babb Jr., president and chief executive officer.

Comerica expects this incremental charge to reduce projected full year 2002
earnings from its previous estimate by up to $0.23 per share.
