MOSCOW, Nov 7 (Reuters) - Russia published a governmentdecree on Monday ordering the sale of a 19.5 percent stake instate-controlled oil giant Rosneft in time for theproceeds to be received by the end of the year.
The decree, signed by First Deputy Prime Minister IgorShuvalov, ordered the sale of stake by state energy firmRosneftegaz to be finalised by Dec. 5, the document showed.
Russia's budget, which is in danger of running up a biggerdeficit this year than the 3.7 percent of gross domestic productenvisaged, needs about 1 trillion roubles ($15.7 billion) intotal from privatisation deals in 2016.
So far, the state has raised 382 billion roubles from salesof shares in diamond producer Alrosa and oil company Bashneft. The rest is expected to come from the stake inRosneft, which bought a 50.1 percent stake in Bashneft inOctober.
Economy Minister Alexey Ulyukayev said in a statement thatthe proceeds from the Rosneft sale were expected to be a minimumof 748.3 billion roubles, and that amount would then be adjustedby a coefficient of 0.95.
That would translate into a minimum of 711 billion roublesin budget proceeds, according to Reuters calculations.
Under the current plan, Rosneft is due to buy the 19.5percent stake itself so the proceeds can fund the budget beforethe end of the year. Rosneft would then resell the shares toinvestors some time in the first quarter of 2017.
At the moment, Rosneftegaz holds a 69.5 percent stake inRosneft. Igor Sechin, Rosneft's chief executive, is alsoexpected to be re-elected as chairman of the Rosneftegaz board,according an Interfax source.
Russian officials have said Rosneft has the funds to buy the19.5 percent stake from Rosneftegaz. Rosneft agreed on Monday tosell a 20 percent stake in its Verkhnechonskneftegaz productionunit for $1.1 billion to China's Beijing Gas.
The deal is subject to regulatory approvals.
