Mallinckrodt public limited company ("Mallinckrodt") acquired Questcor Pharmaceuticals, Inc. ("Questcor") on August 14, 2014.  As Mallinckrodt has previously disclosed, on June 11, 2014, Questcor received a subpoena and Civil Investigative Demand from the Federal Trade Commission ("FTC") seeking documents and information related to the FTC's investigation into whether Questcor's 2013 acquisition of rights to develop and commercialize Synacthen Depot&#174; from Novartis AG and Novartis Pharma AG violates antitrust laws.  Subsequently, a small number of states commenced similar investigations focused on whether the transaction violates state antitrust laws.  Mallinckrodt is fully cooperating in each of these investigations and is not aware of any existing or pending litigation in connection with the investigations.  Mallinckrodt believes the ultimate resolution of these investigations will not have a material adverse effect on its financial condition, results of operations, or cash flows.
