Yukos's Principal Shareholders v. Russia

Yukos conducted its sales through a network of companies registered in a number of low-tax regions in Russia. Following tax investigation, Russian authorities found it had underpaid taxes and held it liable for unpaid taxes, fines, and penalties of USD 24.18 billion. The tax investigations were accompanied by criminal proceedings against and the subsequent imprisonment of some of Yukos's senior management. Following Yukos's unsuccessful attempts to settle its tax debt, the Russian tax authorities sold its core production facility, YNG, in order to satisfy their tax payment demands. YNG was eventually acquired by the state-owned Rosneft. Yukos then went into bankruptcy, with the Russian State owning 97.67 per cent of the claims against it and receiving 99.71 per cent of the bankruptcy proceeds.
