On oct. 3, 2008 Brazilian pulp producer Aracruz said its foreign-exchange derivatives would cause a loss of 1.95 billion reais ($951 million) at current market prices. The company said in a securities filing that despite the fair value loss, the contracts caused cash gains of 25 million reais in the third quarter. Aracruz shares plunged 13 percent shortly after opening on Friday. The stock sank nearly 17 on Sept. 26 when the company said losses with the derivatives exceeded limits set by management, without disclosing details.
