Tibco Software recently agreed to be acquired for $4.2 billion by Vista
Equity Partners. Usually, an announcement such as this ends the
negotiations regarding price. However, in this case,
an error in a spreadsheet
overvalued Tibco by $100 million. As a result, Vista will only have to
pay $4.1 billion for Tibco. The reduction in value will lower the
payment to Tibco shareholders by $.61 per share.
