NEW YORK (TheStreet) -- Lumber Liquidators  (LL - Get Report) stock is down 10.62% to $12.03 on heavy trading volume this morning after reporting a deeper-than-expected 2016 first quarter loss as concerns about the safety of its products persist. 

Before the market open, the hardwood-flooring company reported a loss of $1.20 per share, much wider than the loss of 24 cents per share anticipated by analysts surveyed by Thomson Reuters. 

Lumber Liquidators was negatively impacted by a 20% increase in overhead expenses as it took a $16 million charge related to its consolidated securities class action and a $13.5 million increase in legal and professional fees and related accruals.

The company has been contending with fallout from a report by CBS's "60 Minutes" alleging in March 2015 that Lumber Liquidators had sold Chinese laminate products with dangerously high levels of formaldehyde, which may cause cancer.

Revenue declined 10% year-over-year to $233.5 million, missing analysts' estimates for $237 million. Sales at stores open at least a year fell 13.9% during the most recent period, while analysts were anticipating a 12.6% decline.

"The company believes net sales were impacted by changes in our promotional strategy and continued negative consumer sentiment regarding us," due to the Chinese laminate products, according to a company statement.

Separately, TheStreet Ratings team rates the stock as a "sell" with a ratings score of D+.

Lumber Liquidators's weaknesses include its deteriorating net income, disappointing return on equity, poor profit margins, weak operating cash flow and generally disappointing historical performance in the stock itself.
