Russia 's state-run gas giant OAO Gazprom (GAZP.RS) expects its 2013 net profit to fall 10%, as the cost of producing gas rises, the company's deputy chief executive, Andrei Kruglov, said Thursday, according to the Interfax and Prime news agencies.

He said revenue, and earnings before taxes, depreciation and amortization, or Ebitda, are expected to remain roughly the same as in 2012.

But Mr. Kruglov said the cost of producing gas will rise 1,216 rubles ($37) per 1,000 cubic meters due to rising depreciation charges, taxes and the cost of building new production capacity.
