Shares of K-Swiss Inc. fell more than 10 percent Friday after the casual shoe maker reported a wider fourth quarter loss – despite better-than-expected revenue – and gave a cautious revenue forecast.

The Westlake Village company reported a net loss of $25.2 million (-71 cents a share), compared with a loss of $20.6 million (-58 cents) in the same period a year earlier. Revenue rose nearly 18 percent to $50.2 million.

Analysts surveyed by Thomson Reuters on average expected a loss of 42 cents a share on revenue of $41.4 million.

K-Swiss blamed the profit results on lower gross margins and a one-time charge, and warned that a more than 51 percent drop in future orders likely would hurt revenue this year. Gross margins fell from 34.4 percent to 25.6 percent.

The company expects to report revenue of $240 million to $250 million for this year, compared with the Wall Street consensus of nearly $270 mullion

Shares closed down 40 cents, or 10.7 percent, to $3.35 on the Nasdaq.
