While the Company's expectations are consistent with First Call estimates of a net loss of $0.05 per share for ongoing operations, the Company will incur additional non-recurring charges approximating $8 million during the quarter. The majority of these charges are for additional impairment of the Company's Latin America assets as a result of reclassifying these assets from Discontinued Operations to Continuing Operations, and the remainder is due to personnel-related charges.
