In June 2011, as a result of excess capacity in the PVC pipe market and in an effort to reduce costs and optimize operations, the Company closed its Springfield, Kentucky PVC pipe facility. Asset impairment charges and severance and other costs related to the PVC pipe facility closure recorded in 2011 were $1,975 and $1,389, respectively. The fair value of the impaired assets were determined using internally developed, unobservable inputs (Level 3 inputs in the fair value hierarchy of fair value accounting) based on the projected cash flows of the pipe facility.
