Minor Myers and Charles Korsmo have a new paper that compares fiduciary duty merger litigation to appraisal litigation to determine whether fiduciary duty claims add any value for shareholders.
After scrutinizing takeover challenges between 2004 and 2013, they find that the larger the deal, the more likely it is to be targeted in a fiduciary duty class action. By contrast, whether there is a smaller merger premium – regardless of deal size – does not appear to be correlated with class action litigation. Appraisal litigation, however, works differently; plaintiffs who bring appraisal claims tend to do so when the merger premium is low, regardless of deal size.
They also found that fiduciary suits are not associated with an increase in merger consideration. I.e., they do not generate statistically significant benefits to shareholders.
Myers and Korsmo conclude from this that fiduciary duty class actions are not usually based on merit, and that such actions are brought for their nuisance value. They recommend changes to the structure of fiduciary litigation, such as allowing investors who acquire stock after the deal announcement to serve as lead plaintiff, and switching to an opt-in model.
But there’s a wrinkle that comes in the form of
