Impairment of Long-Lived Asset
When facts and circumstances indicate that the carrying values of long-lived assets, including fixed assets, investments in other companies, may be impaired, an evaluation of recoverability is performed by comparing the carrying value of the assets to projected future cash flows in addition to other quantitative and qualitative analyses. Upon indication that the carrying value of such assets may not be recoverable, the Company recognizes an impairment loss as a charge against current operations. Long-lived assets to be disposed of are reported at the lower of the carrying amount or fair value, less estimated costs to sell. The Company makes judgments related to the expected useful lives of long-lived assets and its ability to realize undiscounted cash flows in excess of the carrying amounts of such assets which are affected by factors such as the ongoing maintenance and improvements of the assets, changes in economic conditions and changes in operating performance. As the Company assesses the ongoing expected cash flows and carrying amounts of its long-lived assets, these factors could cause the Company to realize a material impairment charge.
