CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS	NOTE 3 – CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS At April 30, 2022 and January 31, 2022, significant 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. Due to market conditions, returns on money market instruments are currently minimal. 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 April 30, 2022 and January 31, 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. Interest income is recorded when earned and is included in other income. At April 30, 2022 and January 31, 2022, the weighted average annual interest rates of the outstanding CDs were 0.9% and 0.1%, respectively. 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.
