A series of law suits have been filed by investors over the tender offer for Epicor Software that has been made by Apax Partners and it’s clear that these suits are common when such deals are announced. When Apax said it would spend about $2 billion to buy Epicor and ERP vendor Activant Solutions, several law firms immediately issued press releases saying they were investigating possible breaches of fiduciary duties by the Epicor board. Par for the course.
