The Company had no short-term investments at December 31, 2024. As of December 31, 2023, the Company’s cash equivalents were invested in money market funds and U.S. treasury bills, which were valued based on Level 1 and Level 2 inputs, respectively. As of December 31, 2023, the Company's short-term investments consisted of U.S. treasury bills which were valued based on Level 2 inputs and U.S. Government Agency Securities and foreign national bank securities, which were valued based on Level 2 inputs. In determining the fair value of its short-term investments at December 31, 2023, the Company relied on quoted prices for similar securities in active markets or using other inputs that are observable or can be corroborated by observable market data for Level 2 investments. All available-for-sale securities had contractual maturities of less than one year. The Company did no t have any financial assets or liabilities during any of the periods presented in the accompanying consolidated financial statements that required Level 3 inputs. The carrying values of the Company’s accounts payable and accrued expenses approximate their fair values due to the short-term nature of these liabilities.
