Accrued interest receivables related to our available-for-sale securities of $2.5 million as of April 30, 2026, and $3.2 million as of January 31, 2026, were included within prepaid expenses and other current assets on the consolidated balance sheets. The Company’s short-term investments consist of available-for-sale debt securities and term deposits. The term deposits are at cost, which approximates fair value. The weighted-average remaining maturity of the Company’s investment portfolio is approximately one year as of the periods presented. No individual security incurred continuous unrealized losses for greater than 12 months as of April 30, 2026. The Company purchases investment grade marketable debt securities which are rated by nationally recognized statistical credit rating organizations in accordance with its investment policy. This policy is designed to minimize the Company's exposure to credit losses. As of April 30, 2026, the credit-quality of the Company’s marketable available-for-sale debt securities had remained stable. The unrealized losses recognized on marketable available-for-sale debt securities as of April 30, 2026 was primarily related to the continued market volatility associated with market expectations in the current interest rate environment. The contractual terms of these investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments and it is not expected that the investments would be settled at a price less than their amortized cost basis. 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 basis. The Company is not aware of any specific event or circumstance that would require the Company to change its assessment of credit losses for any marketable available-for-sale debt security as of April 30, 2026. These estimates may change, as new events occur and additional information is obtained, and will be recognized on the consolidated financial statements as soon as they become known. No credit losses were recognized as of April 30, 2026 for the Company’s marketable debt securities.
