Impairment of Long-Lived Assets
The Company reviews long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. While the Companys current operating and cash flow losses are indicators of impairment, the Company believes that the future cash flows to be received from its long-lived assets will exceed their carrying value and, accordingly, has not recognized any impairment losses during the periods presented.
