From Bloomberg News "Concordia Healthcare Corp.’s sale process hit a snag after Blackstone Group and Carlyle Group opted not to pursue a takeover for the Canadian drug maker, according to people familiar with the matter.
The lack of interest from the big private equity firms casts doubt on whether the beleaguered company will find a buyer, said the people, who asked not to be identified as the information is private."
They don't want to be identified so as not to be sued. I bet they sold before releasing the info - insider trading.
