[1] The acquisitions of Innuvate and Treviso are considered step acquisitions, and accordingly, the Company remeasured its pre-existing 27% equity interest in Innuvate and 35% of Treviso immediately prior to completion of the acquisition to its estimated fair value of approximately $39.0 million. As a result of the remeasurement, the Company recorded a gain of approximately $13.6 million within other income (expense), during the first quarter of 2018, representing the excess of the approximate $39.0 million estimated fair value of its pre-existing 27% equity interest in Innuvate and 35% equity interest of Treviso over its transaction date carrying value of approximately $25.4 million.
