A sign for the U.S. fast food restaurant chain McDonald's is seen outside one of their restaurants in Sint-Pieters-Leeuw, near Brussels, Belgium December 3, 2015. EU antitrust regulators will investigate McDonald's tax deals with Luxembourg which enabled the U.S. fastfood chain to escape paying taxes on European franchise royalties from 2009, in a move which could lead to hefty back taxes for the company.
