3. Intangible assets

The Company performs an intangible asset impairment analysis at least annually or whenever circumstances or events indicate such assets might be impaired. The Company would recognize an impairment charge in the event the net book value of such assets exceeded the future undiscounted cash flows attributable to such assets.

Management completed an analysis of the Company's intangible assets as of December 31, 2015. Based on that analysis, the Company concluded that no impairment of the carrying value of the intangible assets existed. The Company believes that no events or circumstances changed during the three and six months ended June 30, 2016 that would impact this conclusion.

Amortization of intangible assets costs was $80 and $161 for the three and six-month periods ended June 30, 2016 and $86 and $173 for the three and six-month periods ended June 30, 2015, respectively.
