Russian mobile firm MTS sees 2015 sales growth slowing

Russia's top mobile phone operator MTS said revenue growth would slow marginally this year but warned that macroeconomic volatility could prompt it to revise its guidance. The company posted an almost 92 percent fall in fourth-quarter net profit, hit by a slump in the rouble because of lower oil prices and a conflict in Ukraine. In Russia, its biggest market, sales growth is seen at more than 3 percent against 5.6 percent last year. It's less than last year but compare it with the mark
