| In accordance with ASC 360 -10, the Company is required to evaluate for impairment when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Upon the occurrence of a triggering event, the Company assesses whether the estimated undiscounted cash flows expected from the use of the asset and the residual value from the ultimate disposal of the asset exceeds the carrying value. In the fourth quarter of 2016, the Company identified a triggering event related to its U.S. segment asset group, which has a carrying amount of $2,339. The Company estimated undiscounted cash flows and determined recoverable amount was in excess of the carrying value, therefore no impairment loss has been recorded in 2016. However, the estimate of undiscounted cash flows is sensitive to certain key assumptions included in these cash flows, such as revenue and margins. As such, the Company will continue to review for impairment triggers which may result in a need to write down those assets to fair value in the future. | | |
