[1] In 2016, the Company recorded a $4,122 impairment charge on core technology and customer relationships. This impairment was based upon forecasted discounted cash flows which considered delayed sales trends with longer than expected sales cycles of Appfluent products, which the Company believes is primarily due to the innovative nature of this solution.
