MOSCOW, Dec 10 (Reuters) - Russian state holding companyRosneftegaz on Saturday signed a deal with the Qatar InvestmentAuthority (QIA) and commodities trader Glencore to sella 19.5 percent stake in state-owned oil major Rosneft,Rosneft said.
The privatisation deal, which Rosneft Chief Executive IgorSechin called the largest in Russia's history, was announced byRosneft in a meeting with President Vladimir Putin on Wednesday.
Its success suggests the lure of taking a share in one ofthe world's biggest oil companies outweighs the risks associatedwith Western sanctions imposed on Russia over the conflict inUkraine.
Rosneft had been under pressure to secure a sale of the 19.5percent stake to help replenish state coffers, hit by aneconomic slowdown driven by weak oil prices and exacerbated bysanctions.
Rosneft said in a statement the budget would receive 710.8billion roubles ($11.37 billion) from the sale, including 18.4billion roubles in additional dividends from Rosneftegaz.
It said the additional dividends were due to a change in itsdividend policy, according to which it will pay at least 35percent of net profit according to international accountingstandards in payouts twice a year.
Rosneft confirmed that Italian bank Intesa Sanpaolo was a major creditor for the deal and said it would be closed bythe middle of December.
Sechin called QIA and Glencore "strategic investors" in theRosneft statement and said he was confident their work togetherwould lead to synergies for Rosneft.
