(1) Per the Company’s investment policy, all debt securities are classified as short-term investments irrespective of holding period.  

(2) Cash equivalents includes liquid demand deposits and money market funds.

The Company invests in U.S. Treasuries, U.S. agency and high-quality municipal bonds which mature at par value and are all paying their coupons on schedule. The Company has therefore concluded an allowance for expected credit losses of its investments was not necessary and will continue to recognize unrealized gains and losses in other comprehensive income (loss). During the three months ended March 31, 2025 and 2024, the Company did not sell any investments. The Company uses the specific investment identification method to calculate realized gains and losses and amounts reclassified out of other comprehensive income (loss) to net loss. As of March 31, 2025, the Company had 6 investments in an unrealized loss position in its portfolio. Gross unrealized losses were not material as of March 31, 2025. Gross unrealized losses were primarily due to declines in the value of fixed rate instruments as interest rates in the broader market increased, and were not indictive of a decline in the credit worthiness of the underlying issuers. Accordingly, the Company did not record a credit loss reserve as of either March 31, 2025 or December 31, 2024.

The following table presents debt securities available-for-sale that were in an unrealized loss position as of March 31, 2025, aggregated by major security type in a continuous loss position. There were no debt securities available-for-sale in an unrealized loss position for less than 12 months as of March 31, 2025.

		Total
		Fair Value		Unrealized Loss

Total		$	17,832	$	(177)

As of March 31, 2025, the Company’s portfolio of available-for-sale securities all have contractual maturities less than or equal to one year.
