Impacted by nearly $1.3 million in litigation charges related to a product liability verdict issued last December, Cybex International reports a net loss of $550,000 for the second quarter ended June 25, worse than the loss of $356,000 sustained in the same period a year ago. The company is appealing the judgment. The loss came despite a sales increase of 17.7 percent to $32.5 million, continuing a trend of double-digit growth for the third quarter in a row, led by Cybex' new treadmill models.
