Valeant’s hostile bid for Allergan was one of 2014’s most discussed takeover battles. The situation, which ultimately resulted in the acquisition of Allergan by Actavis plc, included a novel structure that involved a “partnership” between Valeant and the investment fund Pershing Square. In particular, a Pershing Square-controlled entity having a small minority interest owned by Valeant, acquired shares and options to acquire shares constituting more than nine percent of Allergan’s common stock. Such purchases were made by Pershing Square with Valeant’s consent and with full knowledge of Valeant’s intentions to announce a proposal to acquire Allergan. Pershing Square and Valeant then filed a Schedule 13D and Pershing Square then supported Valeant’s proposed acquisition. Ultimately Pershing Square made a very substantial profit on its investment when Allergan was sold to Actavis.
