CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS	NOTE 5 – CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS At January 31, 2023 and 2022, certain amounts of cash equivalents were invested in money market funds with net assets invested in high-quality money market instruments. Such investments include U.S. Treasury obligations; obligations of U.S. government agencies, authorities, instrumentalities or sponsored enterprises; and repurchase agreements secured by U.S. government obligations. The Company considers all liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. Short-term investments as of January 31, 2023 and 2022 consisted solely of certificates of deposit purchased from Bank of America (the “Bank”) with weighted average initial maturities of less than one year (the “CDs”). The Company has the intent and ability to hold the CDs until they mature, and they are carried at cost plus accrued interest. At January 31, 2023 and 2022, the weighted average annual interest rates of the outstanding CDs were 2.5% and 0.1%, respectively. Dividend income related to our money market investments and interest income on CDs is recorded when earned. Together, the amounts represent the major portions of the net amount of other income except in Fiscal 2022 where other income recorded by APC related to COVID-19 and research and development cost reimbursement payments received from the Irish and U.K. governments totaled approximately $2.8 million. The Company has a substantial portion of its cash on deposit in the U.S. with the Bank. 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. Management does not believe that the combined amount of the CDs and the cash deposited with the Bank and cash balances maintained at financial institutions in Ireland and the U.K., in excess of government-insured levels, represent material risks.
