During the year ended December 31, 2021, we acquired 9,000,000 shares of common stock of Cellebrite DI Ltd (“CLBT”) with a fair value of $90.0 million. The CLBT common stock is recorded as marketable securities in the accompanying consolidated balance sheets and its fair value is adjusted every reporting period. Changes in fair value are recorded in the consolidated statement of operations as unrealized gain or (loss) on marketable securities, which is included in interest and other income, net. During the year ended December 31, 2021, we recorded a $17.8 million unrealized loss on marketable securities from our investment in CLBT.

During the year ended December 31, 2021, we sold held-to-maturity securities with a net carrying amount of $165.4 million prior to their maturity.

Because we do not have any history of losses for our held-to-maturity investments, our expected credit loss reserve methodology for held-to-maturity investments is developed using published or estimated credit default rates for similar investments and current and future economic and market conditions. At December 31, 2020, our credit loss reserve for held-to-maturity investments was approximately $0.2 million.
