Lumber Liquidators’ battle with its product-liability insurers sent the stock down 5.2 percent on Tuesday.

Nine of the hardwood flooring retailer’s insurers are refusing to pay litigation costs associated with the 103 class-action lawsuits filed against the Toano, Va., company over its Chinese-sourced laminated floors.

The lawsuits snowballed after a “60 Minutes” exposé alleged the floors had excessive levels of formaldehyde, a carcinogen that the US government is cracking down on.

The insurers, led by Liberty Mutual, sued the retailer claiming the policies contain a “total pollution exclusion” provision that bars coverage for “bodily injury” or “personal damage” because of the discharge of chemical pollutants into the air.

The company has countersued its insurers in a Wisconsin state court hoping to force them to defend the 103 lawsuits.

The retailers’ shares, down 58 percent already this year, closed Tuesday at $26.60.
