[1] During 2022, the Company recorded an impairment charge of $3,556 in operating expenses with respect to Immervision technology acquired in August 2019, as the Company has decided to cease the development of this product line.

[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 have not been received and have been written off during 2022. Of the $2,200, $210 has not resulted in cash outflows as of December 31, 2022. 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 consolidated statements of income (loss).
