Yukos, once Russia's largest oil company, was declared bankrupt August 1, 2006, after three years of litigation with tax authorities over the company's tax arrears.
Neft-Aktiv was declared the auction winner after it offered 1.03 billion rubles (about $40 million) for the lot compared with the lot's initial price of 992.31 million rubles (about $38.5 million). The other bidders included the companies Akkord and MorTransInvest, the fund said.
The first auction held March 27 to sell Yukos's 9.44% stake in Rosneft was won by Rosneft's subsidiary RN-Razvitiye, which offered 197.84 billion rubles for the lot (about $7.6 billion), compared with the lot's initial price of slightly over 195.5 billion rubles (about $7.5 billion).
The second auction held April 4 to sell a 20% stake in Gazprom Neft was won by a subsidiary of Italy's energy company Eni, which offered 151.53 billion rubles ($5.83 billion) compared with the lot's initial price of 144.77 billion rubles (about $5.57 billion).
However, the Russian energy giant Gazprom will acquire the second lot of Yukos assets under a call option agreement signed with leading Italian energy companies Eni and Enel.
The third auction, including Yukos's research and development assets, was called off due to a lack of bids.
The fourth auction held April 17 for the bankrupt company's energy assets in the Tambov and Belgorod Regions in Central Russia was won by the company Monte-Valle, which offered 3.563 billion rubles (about $138 million) for the lot compared with the lot's initial price of 2.64 billion rubles (about $102.2 million).
Yukos, whose founder Mikhail Khodorkovsky is serving an eight-year prison term in Siberia after being convicted of fraud in May 2005, faces a total of more than 700 billion rubles (about $26.9 billion) in claims from creditors
