The Jones Group has reported revenues for the fourth quarter of $894 million, slightly up from $874 million in the year-earlier period. The company, which owns Nine West and many other properties, said sales were lower than expected due to a highly promotional retail environment and a slowdown in replenishment orders.  However, gross margins were much improved in the quarter, rising to 35.8 percent of sales from 30.8 percent in the comparable year-earlier period, due to the consolidation of Kurt Geiger and an improvement in the group's core businesses, which helped to reduce the quarterly operating loss to $25.9 million from $46.5 million. The net loss for the quarter was $21.1 million, down from $40.1 million. For the full year, revenues reached $3,785 million, compared with $3,643 million in 2010, but operating income dropped slightly to $140.5 million and net earnings fell to $50.7 million from $53.8 million. The group is concentrating on inventory management, cost controls and operational efficiencies to improve margins, as well as on higher-growth segments such as its core brands, upscale and contemporary brands and international development.
