How does Benihana measure the recoverability of restaurant assets when evaluating impairment?

Impairment of Long-Lived Assets and Disposal of Property and Equipment

Long-lived assets, which include property and equipment and right-of-use assets for operating leases, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be fully recoverable. The impairment evaluation is generally performed at the individual restaurant level, as we believe this is the lowest level of identifiable cash flows. We believe that historical cash flows, in addition to other relevant facts and circumstances, are the primary basis for estimating future cash flows. Relevant facts and circumstances include, among others, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for the overall business, and significant negative industry or economic trends. Recoverability of restaurant assets is measured by a comparison of the carrying amount of an individual restaurant's assets to the estimated identifiable undiscounted future cash flows expected to be generated by those restaurant assets. This process requires the use of estimates and assumptions, which are subject to a high degree of judgment. If the carrying amount of an individual restaurant's assets exceeds its estimated undiscounted future cash flows an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds its fair value. The estimated fair value is determined for these assets in accordance with ASC 820.
