Anyone more knowledgeable wanna weigh in here? Far from a corporate attorney, but in my experience, this would be more of a concern if there was a chance this was going private. With Blackrock, Vanguard, Citi, UBS, etc., that definitely won't be the case and those guys are too well protected legally to be left holding the bag.
Maybe in some type of piecemeal sale where rest of company is liquidated? Just thinking out loud but don't think this is a real concern.
