A factory of the Chilean unit of British American Tobacco is seen in Casablanca, on the outskirts of Valparaiso, Chile, July 9, 2015. The Chilean unit of British American Tobacco said on Tuesday it will close various plants in the South American nation after Congress stiffened an anti-tobacco law. The company, one of Chile's largest cigarette manufacturers, called the changes to the law "arbitrary and unconstitutional," and said the measures would cost the government $400 million in annual tax revenue.
