(Bloomberg) – The U.S. Consumer Product Safety Commission ended its probe of Lumber Liquidators Holdings Inc. for selling formaldehyde-laden flooring without issuing a product recall, while calling for corrective measures that the retailer has largely undertaken already.

Lumber Liquidators agreed to not sell laminate flooring made in China — which it stopped offering more than a year ago — and will continue testing the homes of customers who purchased the product, according to a statement on Thursday. The CPSC uses recalls to get faulty products off the market, but didn't take that step in this case. The regulator's examination of the product didn't find unsafe levels of formaldehyde, backing up the results of a testing program the company instituted last year.

The settlement comes after the CPSC began an investigation in March 2015, shortly after the television news program “60 Minutes” reported that Lumber Liquidators sold Chinese-made flooring with unsafe levels of formaldehyde, which has been linked to cancer. The impetus for the report was a lawsuit funded by short sellers, who profit when a stock falls. Another Lumber Liquidators short seller, Whitney Tilson, also pitched the story idea to “60 Minutes.” He then appeared on the program along with the lawyer and environmental advocate who brought the lawsuit.

'Very pleased'

“This affirms what we did,” Lumber Liquidators Chief Executive Officer John Presley said in an interview. “We stopped selling the product, and we tested the product and the tests came back as we expected. We're very pleased with how it turned out.”
