MTS reported good revenue growth reflecting the strengthening of the Russian economy. Operating results for our oil & energy business unit continue to improve, as Bashneft produced its sixth quarter of consecutive increases to production from our acquisition in 2009.   Notably, the recovery we witnessed in the second quarter in our Consumer businesses was sustained in the third quarter, which showed double digit revenue growth and a turnaround in net profitability. In the Technology & Industry business unit we continued to grow our OIBDA margin despite a slight reduction in revenues.

Sistema continues to meet its key strategic goals. Of note is the partnership with the Russian State ivia their investment in our Indian telecom business SSTL and streamlining of our portfolio with our partial sale of Intourist to Thomas Cook and sale of equity in Detskiy Mir-Center to Sberbank.
