                                                                  March 31, 2003



            Fiserv, Inc. Announces a One-Time Loss and One-Time Gain

     Brookfield, Wisconsin, March 31, 2003--Fiserv, Inc. (Nasdaq: FISV)
announced today it incurred a one-time, after-tax realized loss of $10 million
($.05 per share) in the first quarter of 2003 in its Securities Processing
Division that resulted from an apparently fraudulent trading scheme at one of
its broker/dealer clients, and Fiserv also announced it sold investment
securities held by the Company yielding a one-time after-tax realized gain of
$10 million ($.05 per share). After reflecting these events, which together are
neutral to the Company's financial results, Fiserv expects to report earnings
per share for the first quarter of 2003 between $0.37 and $0.39.

     Fiserv has insurance that may cover part or all of this loss; however, no
recovery amount is being recorded pending resolution of a claim. The Company
also intends to pursue all recovery avenues from the broker/dealer and its
principals.

     The broker/dealer client involved in the loss specialized in selling short
for its own account. A recent, sharp rise in the value of a security being sold
short prompted discovery of the apparently fraudulent trading scheme of the
broker/dealer client. Since the broker/dealer client has gone out of business,
Fiserv's Securities Processing Division acting as the clearing broker/dealer
assumed, and bought securities to cover, the obligations associated with the
uncovered short-trading securities positions resulting in the realized loss.
Fiserv considers this loss to be highly unusual and it has not previously
experienced any losses of this nature.

     Fiserv, Inc. (Nasdaq: FISV) provides industry leading information
management systems and services to the financial industry worldwide including
transaction processing, outsourcing, business process outsourcing and software
and systems solutions. The Company serves more than 13,000 clients, including
banks, broker/dealers, credit unions, financial planners/investment
