Oleg Vladimirovich Deripaska (Russian: Оле́г Влади́мирович Дерипа́ска; born January 2, 1968) is a Russian oligarch and philanthropist. He is the founder and owner of one of the largest Russian industrial groups Basic Element. He is the president of En+ Group and United Company Rusal, the second largest aluminium company in the world. After graduating from Moscow State University with a degree in physics, Deripaska became a metals broker specialized in trading aluminium before expanding into energy, machinery, financial services and agribusiness. In 2000, Deripaska founded Rusal, the result of a partnership between Sibirsky Aluminium and Roman Abramovich's Millhouse Capital. In 2007, Rusal merged with SUAL Group and Glencore International AG to form UC Rusal, with Deripaska as chairman. He was once Russia's richest man, worth $28 billion, but nearly lost everything due to mounting debts amid the 2007–08 financial crisis. As of May 2017, his wealth was estimated by Forbes at $5.2 billion. Deripaska is also known for his close ties to Russian president Vladimir Putin, as well as his connection to American political consultant Paul Manafort, whom Deripaska employed from at least 2005 to 2009. Deripaska is also the founder of Volnoe Delo, Russia's largest charitable foundation, and is reported to have donated more than $250 million to mostly educational causes. He is married to Polina Yumasheva, step-granddaughter of former Russian President Boris Yeltsin and daughter of Valentin Yumashev, Yeltsin's son-in-law and close advisor.
