Trading was temporarily halted Monday in Lumber Liquidators after its shares dropped by more than 20 percent following a "60 Minutes” report that claimed the company sold flooring with higher levels of formaldehyde than permitted under California's health and safety standards (CARB), NBC News reported. The segment that aired Sunday said it sent Lumber Liquidators' flooring in Virginia, Florida, Texas, Illinois and New York to certified labs to test for levels of formaldehyde, a cancer-causing chemical. Out of the 31 samples, only one was compliant with formaldehyde emissions standards. In a statement released Monday, Lumber Liquidators said: "We stand by every single plank of wood and laminate we sell all around the country and will continue to deliver the best product at the best price to our growing base of valued customers."
