These investments were in loss for less than 12 months and the Company considers the loss to be temporary in nature.

In accordance with the Company’s investment policy, it places investments in investment grade securities with high credit quality issuers, and generally limits the amount of credit exposure to any one issuer. The Company evaluates securities for impairment at the end of each reporting period. The Company did not record any impairment charges related to its available-for-sale securities during years ended December 31, 2022 and 2021. The Company did not recognize any credit-related allowance to available-for-sale securities as of the years ended December 31, 2022 and 2021.
