As of April 30, 2025 and January 31, 2025, net unrealized gains on the Company’s U.S. government treasury securities were approximately $8.4 million and $1.5 million, respectively. These net unrealized gains were caused by fluctuations in interest rates, which results in changes to the market value of these securities. Since the fluctuation in fair value is due to changes in interest rates and not credit quality, and because the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, the Company concluded that an allowance for credit losses was unnecessary for short-term investments as of April 30, 2025. Gross realized gains and losses were not material for each of the three months ended April 30, 2025 and 2024. There were no material short-term investments in a continuous loss position for greater than twelve months.
Non-marketable Securities
As of April 30, 2025 and January 31, 2025, the total amount of non-marketable equity securities included in other assets on the Company’s condensed consolidated balance sheets were $28.7 million and $24.2 million, respectively. The Company made an additional investment of $5.0 million of its cash in non-marketable equity securities during the three months ended April 30, 2025. The Company did not make additional investments during the three months ended April 30, 2024. The Company recognized an immaterial net unrealized loss on certain of these non-marketable securities during both of the three months ended April 30, 2025 and 2024.
