MOSCOW, October 14. /TASS/. Standard & Poor's (S&P) confirmed the long-term corporate credit rating of Russian oil producer Rosneft at "BB+" with stable outlook, the international rating agency said on Friday.

"The affirmation reflects our view that Rosneft's credit metrics will not weaken materially after its acquisition of Bashneft," S&P said. "From a business prospective, we think the Bashneft transaction somewhat enhances Rosneft's business risk profile," the rating agency reported.

Rosneft closed the deal on acquisition of 50.08% of shares in Bashneft from the Russian government for 329.7 bln rubles ($5.2 bln) on October 12.
