Dec. 6 (Bloomberg) -- OAO Mechel, Russia’s largest producer of steel-making coal, fell the most in a month in U.S. trading after the miner stopped work at two sites amid safety concerns.
Mechel’s American depositary receipts dropped 11 percent to $10.45 in New York, the biggest decline since Nov. 9.
Several facilities at the company’s Lenin and New- Olzherassk mines were shut following complaints to the Siberian branch of Russia’s industrial safety watchdog, Mechel said in a statement today.
