Due to changing and deteriorating conditions in the automotive industry and reduced production requirements between 2006 and 2009, we ceased production at several of our facilities, including our Pittsburg, Kansas and Johnson City, Tennessee facilities. As a result of these plant shut-downs and the analyses of our long-lived assets, we recorded impairment charges related to the long-lived assets associated with facilities reducing the carrying value of certain assets at the facilities to their respective fair values.

The excess property, plant and equipment associated with the closed facilities that were being actively marketed for sale were included in assets held for sale. During 2011 and 2010, the estimated fair values of certain of these assets declined to an amount that was less than their respective book values, resulting in additional asset impairment charges of $1.3 million and $1.2 million, during 2011 and 2010, respectively. The fair value of these assets was determined based upon comparable sales information and with the assistance of independent third party appraisers and we had classified the inputs to the nonrecurring fair value measurement of these assets as being level 2 within the fair value hierarchy in accordance with U.S. GAAP. During 2011, impairment charges of $1.3 million related to our idle Pittsburg, Kansas and Johnson City, Tennessee facilities were recorded because the fair values were determined to be less than their remaining book values based on negotiations for the sales of the assets. During the third quarter of 2012, we completed the sale of the idle Pittsburg, Kansas facility for $2.0 million, and the purchase price less commission and fees was collected in cash, consistent with the carrying value. During 2011, the company completed the sale of the closed Johnson City, Tennessee facility for $1.7 million, and the purchase price less commission and fees was collected in cash, consistent with the carrying value.

Below is a summary of the long-lived asset impairment charges discussed above:
