The gross unrealized losses on the Company's marketable debt securities were not material as of December 31, 2021 and 2020.
 
As of December 31, 2021, and 2020, interest receivable amounted to $2,635 and $4,376, respectively, and is included within marketable securities in the consolidated balance sheets.
 
Effective June 2021, an equity investment in a privately held company no longer qualifies for the use of the measurement alternative, as the fair value of the investment became readily determinable. The investment was therefore transferred from measurement alternative to equity securities with readily determinable fair value. For more details see Note 2.k.
 
As of December 31, 2021, marketable equity securities with readily determinable fair values, carried at fair value, amounted to $312,934. Unrealized gains recognized during the year ended December 31, 2021 were $249,561.
