Impairment Loss [Abstract]
Impairment Loss	7. Impairment Loss Goodwill impairment The Company performs impairment tests on goodwill on an annual basis in accordance with US GAAP, or more frequently if events or changes in circumstances indicate that those assets might be impaired. Goodwill is tested for impairment at a reporting unit level, which is at the same level or one level below an operating segment. A goodwill impairment loss is recognized when the carrying amount of the reporting unit is greater than its fair value. The goodwill impairment loss is calculated as the excess of the carrying amount of the goodwill over its implied fair value. During the years ended December 31, 2018 and 2017, there was no goodwill impairment identified. Goodwill arising from the acquisition of AssetNation, the provider of an online marketplace, was part of the former EquipmentOne reporting unit. During the year ended December 31, 2016, an indicator of impairment was identified with respect to the EquipmentOne reporting unit. The indicator consisted of a decline in actual and forecasted revenue and operating income compared with previously projected results, which was primarily due to the recent performance of the EquipmentOne reporting unit. Based on the results of the goodwill impairment test, the Company recorded an impairment loss on the EquipmentOne reporting unit goodwill of $23,574,000 in the year ended December 31, 2016. Long-lived asset impairment Long-lived assets, which are comprised of property, plant and equipment and definite-lived intangible assets, are assessed for impairment whenever events or circumstances indicate that their carrying amounts may not be recoverable. For the purpose of impairment testing, long-lived assets are grouped and tested for recoverability at the lowest level that generates independent cash flows from another asset group. The carrying amount of the long-lived asset group is not recoverable if it exceeds the sum of the future undiscounted cash flows expected to result from the long-lived asset group’s use and eventual disposition. Where the carrying amount of the long-lived asset group is not recoverable, its fair value is determined in order to calculate any impairment loss. An impairment loss is measured as the excess of the long-lived asset group’s carrying amount over its fair value. During the year ended December 31, 2017, management identified indicators of impairment on certain software and software under development intangible assets (the “technology assets”). The indicators consisted of decisions made after the acquisition of IronPlanet that adversely impacted the extent or manner in which certain technology assets would be utilized. As part of its integration activities the Company determined that it was more likely than not that certain technology assets would not be utilized or developed as originally intended and no longer had value. As a result, management performed an impairment test that resulted in the recognition of an impairment loss of $8,911,000 on the technology assets. At September 30, 2016, for the same reason noted above under the EquipmentOne goodwill impairment test, management determined that there was an indicator that the carrying amount of the long-lived assets arising from our acquisition of AssetNation (the “EquipmentOne long-lived assets”) might not have been recoverable. As such, the Company performed the recoverability test, for which purpose management determined that the asset group to which the EquipmentOne long-lived assets belonged was the EquipmentOne reporting unit. Based on the results of the long-lived asset impairment test, the Company recorded an impairment loss on the EquipmentOne reporting unit customer relationships of $4,669,000 in the year ended December 31, 2016. In connection with this impairment loss, the Company recorded a deferred tax benefit of $1,798,000 to the income tax provision. The result of this impairment test was reflected in the carrying value of the former EquipmentOne reporting unit prior to the completion of the goodwill impairment test described above.
