	(in thousands)

The amortized cost and fair value amounts include accrued interest receivable of $0.5 million as of January 31, 2023. There were no short-term investments as of January 31, 2022 and 2021.

The U.S. treasury securities are marketable debt securities stated on the consolidated balance sheets at fair value based upon inputs other than quoted prices in active markets (Level 2 inputs). The Company recorded $0.4 million unrealized losses as a component of other comprehensive loss for the year ended January 31, 2023. The Company did not recognize any gains or losses for the year ended January 31, 2023.

As of January 31, 2023, all of the available-for-sale debt securities were in a continuous unrealized loss position for less than twelve months. During the year ended January 31, 2023, the Company did not recognize credit-related impairment losses and had no ending allowance for credit losses. The decline in fair value below amortized cost basis was not considered other than temporary as it is more likely than not the Company will hold the debt securities until maturity or a recovery of the cost basis.

As of January 31, 2023, all of the marketable debt securities have contractual maturities of less than one year.
