In May 2016, the Company was served with a False Claims Act case brought by a former emergency department service associate who worked at a hospital of one of the Company’s customers, MedStar Inc.’s Washington Hospital Center (“WHC”), along with WHC and three other hospitals that were PAS clients and a place holder, John Doe hospital, representing all PAS clients (USA ex rel.
