Could you identify your source for this? I find a reference to the 2014 expiration in the 2012 10-K filed last March. At the time of the merger with Prospect Acquistion Corp in 2009 the terms were set for the wts to expire in November 2013 and this date is used in all previous 10-K's up to March 2012. There is no public announcement of the change in any 8-K's from 01/2012 through the 03/2013 10-K filing.
Typically for blank check cos. like Prospect their wts expire 5 years after the date of acquisition or merger so 2014 is consistent with that. But unless they misreported the exp date in the merger announcement and subsequent reports since, a change had to have been made and that would have to have been made public. Also, they've purchased millions of the wts on the open market to minimize dilution, so I'm wondering how that would factor into the decision to extend, if in fact they were extended.
