As of July 31, 2025, the Company held 49 securities, 42 of which, with an aggregate fair value of $140.6 million, were in an unrealized loss position. All investments in an unrealized loss position were in this position for less than 12 months and there has been no change in the credit risk of such securities during the three and nine months ended July 31, 2025. The Company does not intend to sell its investments and it is not more likely than not that the Company will be required to sell the securities before recovery of the amortized cost basis of its debt securities. No allowance for credit losses was recorded as of July 31, 2025 because the decline in fair value below amortized cost is not related to credit losses. Securities are evaluated at the end of each reporting period for evidence of the credit-related impairment. The unrealized losses on U.S. treasury and government agency securities range from 0-1% of their amortized cost.
