Others:

In fiscal 2017, IDT purchased substantially all of the assets and liabilities of Synkera Technologies, Inc. (Synkera) for total purchase consideration of approximately $2.8 million, of which $1.5 million was paid in cash at closing and $1.3 million was recorded as a liability representing the fair value of contingent cash consideration of up to $1.5 million. The liability was recognized for the Company’s estimate of the fair value of contingent consideration on the acquisition date based on probability-based attainment of certain milestones. This fair value measurement is based on significant inputs not observed in the market and thus represents a Level 3 measurement, which reflects the Company’s own assumptions concerning the milestones related to the acquired business in measuring fair value. During the nine months ended December 30, 2018, the Company paid $0.7 million upon the achievement of certain milestones. The fair value of the liability measured using significant unobservable inputs (Level 3) was approximately $0.6 million and $1.3 million as of December 30, 2018 and April 1, 2018, respectively.
