​ As of July 31, 2024 and January 31, 2024, interest receivable in the amounts of $1.6 million and $1.3 million, respectively, were included in the balances of AFS securities. For the three and six months ended July 31, 2024 and 2023, there were no sales of the Company’s AFS securities and, therefore, there were no amounts of gains or losses reclassified out of other comprehensive income into net income. The Company does not believe the unrealized losses represent credit losses based on the evaluation of evidence as of July 31, 2024 and January 31, 2024, which includes an assessment of whether it is more likely than not the Company will be required to sell or intends to sell the investments before recovery of their corresponding amortized cost bases. ​ Earnings on Investments Earnings on investments for the three and six months ended July 31, 2024 were $4.8 million and $9.3 million, respectively, and they were $3.3 million and $5.7 million for the three and six months ended July 31, 2023, respectively. Earnings on investments are included in other income, net, in the consolidated statements of earnings. Concentration Risk The Company has a substantial portion of its cash on deposit in the U.S. with the Bank or invested in CDs purchased from the Bank. In addition, the Company has cash invested in a money market fund at a separate institution. The Company also maintains certain Euro-based bank accounts in Ireland and certain pound sterling-based bank accounts in the U.K. in support of the operations of APC. As of July 31, 2024 and January 31, 2024, approximately 1% and 12%, respectively, of the Company’s cash and cash equivalents were held by financial institutions in Ireland and the U.K. Management does not believe that the combined amount of the CDs and the cash deposited with the Bank, cash invested in the money market fund, and cash balances maintained at financial institutions in Ireland and the U.K., in excess of government-insured levels, represent material risks.
