peopleSoft's Poison pill

In 2003, the management of PeopleSoft, Inc., a company that provided human resource management systems, was concerned about a takeover by Oracle, a company specializing in database management systems. it took the unusual step of guaranteeing to its customers that, if it were acquired within two years and product support was reduced within four years, its customers would receive a refund of between two and five times the fees paid for their software licenses. The hypothetical cost to Oracle was estimated at $1.5 billion. The guarantee was opposed by PeopleSoft's shareholders.(It appears to be not in their intetests.) PeopleSoft discontinued the guarantee in April 2004. Oracle did succeed in acquiring PeopleSoft in December 2004. Although some jobs at PeopleSoft were eliminated, Oracle maintained at least 90% of PeopleSoft's product development and support staff.
