It was reported earlier that the Arbitration Institute of the Stockholm Chamber of Commerce obliged Naftogaz Ukrainy on June 8, 2010 to return RosUkrEnergo 11 billion cubic meters of gas and also pay it a penalty of 1.1 billion cubic meters of gas, as stipulated by the contract. Naftogaz, in turn, returned 12.1 billion cubic meters of gas to RosUkrEnergo after buying the necessary amount from Russia's Gazprom at $230 per 1,000 cubic meters.
