A 2012 study of Burisma Holdings done in Ukraine by the AntiCorruption Action Centre (Antac), an investigative nonprofit co-funded by American billionaire George Soros and the U.S. State Department, found that the true owner of Burisma Holdings was none other than Ukrainian billionaire-oligarch Ihor Kolomoysky.
The study, which was funded to dig up corruption on the Ukrainian President Viktor Yanukovych, instead found that Ihor Kolomoysky "managed to seize the largest reserves of natural gas in Ukraine".
Burisma Holdings changed owners in 2011 when it was taken over by an off-shore Cyprus enterprise called Brociti Investments Ltd, and subsequently, moved addresses under the same roof as Ukrnaftoburinnya and Esko-Pivnich, two Ukrainian gas companies which happened to be also owned by Kolomoysky through off-shore entities in the British Virgin Islands.
