Asset Impairment Charges [Text Block]	Note 6. Asset Impairment Charges Long-lived assets classified as held and used and definite-lived intangible assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. An estimate of future undiscounted net cash flows associated with the long-lived assets is used to determine if the carrying value of the assets is recoverable. An impairment charge is recorded if the asset is determined to not be recoverable and the carrying value of the asset exceeds its fair value. In the first quarter of 2012 and 2011, triggering events were determined to have occurred related to certain properties due to changes in the expected future use. We evaluated the future undiscounted net cash flows for each property and determined the carrying value was not recoverable. We concluded the carrying value of the assets exceeded the fair value and, as a result, we recorded asset impairment charges of $0.1 million and $0.4 million, respectively, for three months ended March 31, 2012 and 2011 in our Consolidated Statements of Operations.
