A double-digit slump in sales led to a widening of Columbia Sportswear's second quarter losses to US$9.9m - but the company reaffirmed its full-year guidance.

Net sales at the US company fell 16% to $179.2m in the period ended 30 June, leading to a net loss of $9.9m, compared to a loss of $1.8m in the same period last year.

Columbia was at pains to point out that the quarter is typically its smallest in terms of revenue, accounting for about 15% of total annual sales.

The decline was led by Europe, the Middle East and Africa, where sales slumped by 47% to $33.7m, and by Canada, where a 44% decline brought revenues of $7.9m.

This was partly offset by a 2% increase in US net sales, while revenues for Latin America and Asia-Pacific were largely flat.

By category, sportswear sales suffered a 15% decline to $98.4m, while footwear dropped 21% to $33.4m and outerwear fell 16% to $35.1m.

Accessories and equipment were down 8% to $35.1m. And by brand, revenues for the dominant Columbia label fell 17% to $162m, while the combined sales for Mountain Hardwear, Sorel and Montrail declined 9% to $17.2m.

Columbia Sportswear president and CEO Tim Boyle said the results were marginally better than the company's April guidance, but added: "The global retail environment continued to provide significant headwinds which we expect to persist through at least the remainder of 2009 and into 2010."

The company reaffirmed its full-year guidance of sales falling by low single digits, with a low double-digit decline in net sales for the third quarter.
