[1] Changes to the estimated fair value of contingent consideration were primarily due to revisions to the Company's expectations of earn-out achievement.
[2] In connection with the acquisition of Physpeed, the Company recorded contingent consideration based upon the expected achievement of certain 2015 and 2016 revenue milestones. Changes to the fair value of contingent consideration due to changes in assumptions used in preparing the valuation model are recorded in selling, general and administrative expense in the statement of operations.
