Leading producer of seamless intimate apparel Tefron Ltd on Thursday revealed it more than doubled its fourth quarter net loss as it was hit by restructuring charges and one-time expenses related to its wholly-owned US facility. The Bnei-Brak based company, which makes lingerie for leading brands such as Victoria's Secret, Gap, Banana Republic, Target, Nike, JC Penney, and Adidas, posted a net loss of $3.5 million compared to $1.4m in 2001.
