It isn't just investors who bought CBT stock that are chasing the Irish software company for compensation, with a whole plethora of class action suits now lodged against the company. Now shareholders in Forefront, the US software group bought by CBT last March, are looking for compensation.

That deal between Forefront and CBT was an all-paper transaction and the value of CBT shares taken by Forefront shareholders was then $147 million (£96.5 million). That was when CBT was trading above $40, but the $147 million worth of CBT shares last March is now worth less than $40 million, and former Forefront shareholders are very unhapppy, especially as the takeover was all-paper with no cash alternative.

Now the class action suit lodged in the California courts accuses the registration document of misrepresentation - the usual US lawyer speak for "settle or else".

The queue of lawyers lodging class action suits gets longer and longer.
