PFO Global, which recently came under new management, reported a net loss of $15.7 million for the year ended last Dec. 31, up from a loss of $8.5 million in the prior year. Sales went up by 13 percent to $3.4 million at the American company previously led by Ruedi Suter, with higher sales of prescription lenses and complete glasses partially offset by lower revenues from safety kiosk software. Operating expenses grew by $4.8 million to $12.1 million, chiefly due to a $4.1 million goodwill impairment charge taken relation to its June 30 merger. Interest charges went up.
