ITEM 5.  OTHER EVENTS

         On July 20, 1999, the Corporation announced an agreement to acquire
         First Data Investor Services Group, Inc. (ISG), the mutual fund
         servicing subsidiary of First Data Corp. for $1.1 billion in cash. The
         transaction is expected to close in the fourth quarter of 1999, pending
         regulatory approvals and satisfaction of customary closing
         conditions. A copy of the press release issued by the Corporation is
         attached hereto as Exhibit 99.1 and incorporated herein by reference.
         Certain information made available by the Corporation with respect to
         the acquisition of ISG is attached hereto as Exhibit 99.2 and
         incorporated herein by reference.

         The information in Exhibits 99.1 and 99.2 contains forward-looking
         statements within the meaning of the Private Securities Litigation
         Reform Act, which are based upon numerous assumptions and estimates
         relating to future operations and are subject to the risks and
         uncertainties described therein, among others. Many of these matters
         are difficult to predict and may change over time. Forward-looking
         statements contained within Exhibits 99.1 and 99.2 are not guarantees
         of future performance. Actual results may differ materially from the
         Corporation's current expectations. The Corporation assumes no
         obligation to correct or update forward-looking statements to reflect
         actual results, changes in assumptions or changes in other factors
         affecting forward-looking statements or if the Corporation later
         becomes aware that they are not likely to be achieved.
