Schedule of Contingent Consideration

Acquisitions

Contingent Consideration

In connection with certain of the Company’s acquisitions, contingent consideration is payable in cash or common stock upon the achievement of certain performance measures over future periods. The Company recorded the acquisition date fair value of the contingent consideration liability as additional purchase price. The process for determining the fair value of the contingent consideration liability consists of reviewing financial forecasts and assessing the likelihood of reaching the required performance measures based on factors specific to each acquisition as well as the Company’s historical experience with similar arrangements. Subsequent to the acquisition date, the Company estimates the fair value of the contingent consideration liability each reporting period and any adjustments made to the fair value are recorded in the Company’s results of operations. If an acquisition reaches the required performance measures within the reporting period, the fair value of the contingent consideration liability is increased to 100%, the maximum potential payment and reclassified to Due to seller.

On June 30, 2017, the EYELEVEL acquisition reached the required performance measures at the end of its earnout period and the balance of the fair value of the contingent consideration liability was reclassified to due to seller. During the third quarter of 2017 the company paid $17.7 million to settle the final balance owed to the sellers. As of December 31, 2018 and 2017, there are and were no outstanding contingent consideration liabilities.

During the twelve months ended December 31, 2018 and 2017 and 2016, the Company recorded expense of $0.0 million, $0.7 million and $10.4 million, respectively, due to changes in the fair value of the contingent consideration liability.
