CAIRO May 15 (Reuters) - Egyptian mobile phone operator Orascom Telecom Holding said on Wednesday it swung to a net loss in the first quarter of 2013, blaming foreign exchange losses and impairment of some assets.
The firm, controlled by Russia's Vimpelcom, made a net loss before minority interests of $204 million for the quarter compared to a profit of $120.4 million a year earlier, it said in a statement.
It said the loss was "mainly driven by the adverse impact of foreign exchange losses of $173 million and the impairment of assets held for sale by $58 million, as to reflect the fair value of our operations in CAR (Central African Republic) and Burundi."
Orascom said it made revenue of $849 million for the quarter, a decline of about 1 percent over the previous year. Total subscribers increased 3 percent from a year earlier to about 85 million.
The firm's management on Tuesday recommended shareholders reject an offer by a subsidiary of Russian billionaire Mikhail Fridman's Altime to buy the company for $0.70 a share.
It said an independent financial adviser had put a fair value on Orascom's shares of $0.86 per share.
Orascom has mobile businesses in Canada, Algeria and other emerging markets such as Bangladesh. (Reporting by Alexander Dziadosz; Editing by Tom Pfeiffer)
