This document summarizes recent developments in antitrust enforcement and investigations. It notes that in 2012, the DOJ obtained over $1 billion in criminal antitrust fines, driven by large fines against companies involved in price fixing for auto parts and LCD screens. It predicts that the investigations into auto parts and alleged rigging of LIBOR interest rates will remain active areas in 2013 and potentially yield further prosecutions and penalties. While 2012 saw record fines, fewer new criminal antitrust cases were actually filed compared to 2011.
