Goodwill Disclosure [Abstract]
Goodwill	10. GOODWILL Goodwill, all of which relates to our acquisitions of Bluesocket, Inc. in 2011 and SmartRG in 2018, was $7.0 million and $7.1 million at September 30, 2019 and December 31, 2018, respectively, of which $6.6 million and $0.4 million was allocated to our Network Solutions and Services & Support reportable segments, respectively, as of September 30, 2019, and of which $6.7 million and $0.4 million was allocated to our Network Solutions and Services & Support reportable segments, respectively, as of December 31, 2018. Goodwill related to our SmartRG acquisition was reduced by $0.1 million during the nine months ended September 30, 2019 as a result of a measurement period adjustment. We evaluate the carrying value of goodwill during the fourth quarter of each year and between annual evaluations if events occur or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. We have elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit to which the goodwill is assigned is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. If we determine that it is more likely than not that its fair value is less than its carrying amount, then the two-step impairment test will be performed. Based on the results of our qualitative assessment in the fourth quarter of 2018, we concluded that it was not necessary to perform the two-step impairment test. No events or circumstances occurred during the nine months ended September 30, 2019 that would more likely than not reduce the fair value of goodwill below its carrying value.
