KIEV, June 6 – Naftogaz Ukrayiny CEO Andriy Kobolev predicts that the calculation of the compensation that is due to the Ukrainian company under a separate ruling by the Arbitration Institute of the Stockholm Chamber of Commerce in the dispute with the Russian gas monopolist Gazprom will take two to three months.

"We have managed to revise the price starting from 2014, which means that Gazprom will have to compensate us a certain amount for all the gas that Naftogaz bought from the Russian Gazprom starting from that date. The final calculations of the compensation by both parties will take about two to three months, according to my estimates," he said on the air of the "1+1" Channel.
