Champagne house, Laurent-Perrier, reported a 3.5% increase in sales in the nine months to December 31 in spite of depressed market conditions. The company's sales for the nine months stood at EUR121.8 million against EUR117.7 million in the corresponding period a year earlier. The company attributed its relatively robust performance to its lack of exposure to the particularly weak US market. Laurent-Perrier, the fifth largest Champagne producer, only derives about 6% of its sales from the US.
