Minneapolis -- Christopher & Banks Corp. narrowed its fiscal fourth-quarter loss as the company received a boost from an extra week of sales and cut costs.

The retailer posted a loss of $4.1 million for the 14 weeks through Feb. 2, compared with a loss of $53.2 million in the 13 weeks the year before.

Revenue was up 10%, to $116 million from $105.6 million. Same-store sales jumped 18.5%.

Total expenses fell 25% to $120 million.

Christopher & Banks has been closing poor-performing stores and cutting costs to help turn its business around.

"We intend to continue to build upon this foundation to drive sustainable long-term sales and earnings growth," CEO LuAnn Via said in a statement.
