Russian diamond mining company Alrosa said Monday that it had a net loss of 16.8 billion rubles ($283.28 million) in 2014 due to the revaluation of the dollar-denominated part of its debt portfolio caused by a weaker ruble.
The miner, the world's top producer by output in carats, said its revenue rose 23 percent to 207.2 billion rubles and earnings before interest, taxes, depreciation and amortisation grew by 36 percent to 93.9 billion rubles.
