TOANO, VA  -- Earnings at Lumber Liquidators, whose flooring sales have been growing rapidly with housing and economic recovery, will be closely watched when they are announced July 24.

Lumber Liquidators (NYSE: LL), the largest specialty retailer of hardwood flooring in North America, said in last quarter's SEC filing that it is uncertain of the impact on its business of an antidumping and countervailing duties investigation.

In October 2010, a conglomeration of domestic manufacturers of multilayered wood flooring filed with the United States Department of Commerce and the United States International Trade Commission against imports of multilayered wood flooring from China. Lumber Liquidators sources some flooring from China, where it acquired a business in 2012.

Lumber Liquidators opened its 300th store, located in Las Vegas, NV last month, described as its "store of the future" format. Its stock fell last month following a report by a financial analyst who says he found evidence of formaldehyde its flooring.
