The Company regularly assesses whether events and circumstances with the potential to trigger impairment have occurred and relies on a number of factors, including operating results, business plans, economic projections, and anticipated future cash flow, to make such assessments. The Company uses an estimate of the future undiscounted cash flows of the related asset or asset group over the estimated remaining life of such asset(s) in measuring whether the asset(s) are recoverable. Measurement of the amount of impairment, if any, is based on the difference between the carrying value of the asset(s) and the estimated fair value of such asset(s). Fair value is determined through a series of standard valuation techniques.</font></div><div style="line-height:120%;padding-top:8px;text-align:left;text-indent:20px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">During </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">2010</font><font style="font-family:inherit;font-size:10pt;">, the Company recorded a </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$2.0</font><font style="font-family:inherit;font-size:10pt;"> impairment charge to write down the carrying amount of idled equipment to represent its estimated fair value and a </font><font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;">$1.9</font><font style="font-family:inherit;font-size:10pt;"> impairment charge in connection with the sale of its Greenwood, South Carolina facility.
