A sign is pictured in front of the Vitol Group trading commodities building in Geneva October 4, 2011. The two Pemex documents are also not public. As part of the settlement, Vitol also dropped a lawsuit against PMI Comercio Internacional, Pemex's international trading arm, for $1.21 million for alleged damages to a refinery in Cressier, Switzerland. Meanwhile, legal proceedings tied to the graft scandal continue in Mexico but also the U.S., where a former employee is on trial, and Ecuador. The graft scandal Vitol acknowledged dates back to Lopez Obrador's predecessors.
