"We are intensely focused on returning the company to profitability as quickly as possible," i2 chairman and chief executive officer Sanjiv Sidhu said.
"As the leading supply chain vendor in the market today, we will be aligning our sales efforts, product development and delivery for maximum business efficiency, while never losing sight of our customers."

Despite the losses, i2 claimed it had 77 customers go live with supply chain products during the quarter. Among these companies were Adidas-Salomon, Barnes & Noble and Nippon Steel.
