Marketable securities classified as current have maturities of less than one year and are classified as available-for-sale. Marketable securities classified as non-current are those that: (i) have a maturity of greater than one year, and (ii) are not intended to be liquidated within the next twelve months, although these funds are available for use and, therefore, are

classified as available-for-sale. No available-for-sale debt securities held as of March 31, 2024 or December 31, 2023 had remaining maturities greater than five years.

Based on factors such as historical experience, market data, issuer-specific factors, and current economic conditions, the Company did not record an allowance for credit losses at March 31, 2024 and December 31, 2023, related to these securities.
