[1] The estimated fair values are preliminary and based on information that was available as of the closing date (see note 3).

[2] During the first quarter of 2018, the Company entered into an agreement to acquire certain NB-IoT technologies in the amount of $2,800, of which technologies valued at $600 has not been received. Of the $2,200, $210 has not resulted in cash outflows as of June 30, 2021. In addition, the Company participated in programs sponsored by the Hong Kong government for the support of the above investment, and as a result, the Company received during 2019 an amount of $239 related to the NB-IoT technologies, which was reduced from the gross carrying amount of intangible assets. The Company recorded the amortization cost of the NB-IoT technologies in “cost of revenues” on the Company’s interim condensed consolidated statements of income (loss).
