Igor Rotenberg acquired significant assets from his father, Arkady Rotenberg, a former judo partner of Putin. The older Rotenberg became a billionaire from business interests developed while Putin consolidated political power. The assets Arkady has sold to his son Igor include 79 percent of drilling company Gazprom Drilling (Bureniye); 28 percent of road construction company Mostotrest; and 33 percent in TPS Real Estate Holding. Igor Rotenberg, in a written statement, told Reuters: “Of course my father gave me a good start in business. Today I am an independent businessman and I am developing my assets with my team in a competitive, market environment.” Igor Rotenberg’s uncle, Boris Rotenberg, owns 16 percent of Gazprom Burenie. Like his brother Arkady Rotenberg, Boris Rotenberg was designated in March 2014.
