Russian oil company Rosneft has bought 9.44% of its shares that had been owned by Yukos, paying €5.7 billion for a package of assets at auction.
There were two bidders for the Rosneft stake: Rosneft subsidiary RN-Razvitie and Samotlorneftegaz, a subsidiary of British joint venture TNK-BP.
Analysts had fully expected Rosneft to win, saying that the participation of TNK-BP, which is 50% owned by Britain's BP, was a gesture intended to dignify the controversial sale of a key Yukos asset.
The auction marks the final chapter in the disintegration of Yukos, which became Russia's largest oil company under its now jailed former boss Mikhail Khodorkovsky.
Yukos was dismembered in a series of court cases after Khodorkovsky was arrested at a Siberian airport in October 2003.
The company's fall cast a shadow over President Vladimir Putin's reputation abroad. Critics in Russia and the West have said the Kremlin drove a politicised series of court cases to destroy Yukos, neutralise Khodorkovsky's political ambitions and restore company assets to state hands.
The former Yukos management, much of which has fled Russia, had argued against the bankruptcy proceedings, saying that the company was actually in profit.
Khodorkovsky and other key figures involved in the company are serving prison terms, with the former chief executive serving eight years on embezzlement charges in Russia's Far Eastern province of Chita.
State-controlled Rosneft, now the second-biggest Russian oil producer after Lukoil, bought Yukos' main production unit, Yuganskneftegaz, in 2004.
