CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS	NOTE 3 – CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS At July 31, 2021 and January 31, 2021, significant amounts of cash equivalents were invested in government and prime money market funds with net assets invested in high-quality money market instruments. Such investments include US Treasury obligations; obligations of US government agencies, authorities, instrumentalities or sponsored enterprises; and repurchase agreements secured by US 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 July 31, 2021 and January 31, 2021 consisted solely of certificates of deposit purchased from Bank of America (the “Bank”) with weighted average initial maturities of less than one year. The Company has the intent and ability to hold the CDs until they mature, and they are carried at cost plus accrued interest which approximates fair value. Interest income is recorded when earned and is included in other income. At July 31, 2021 and January 31, 2021, the weighted average annual interest rates of the outstanding CDs was 0.2% at each period end. The Company has a substantial portion of its cash on deposit in the US. The Company also maintains certain Euro-based bank accounts in Ireland and certain pound sterling-based bank accounts in the UK in support of the operations of APC. Management does not believe that the combined amount of the CD investments and the cash deposited with the Bank and financial institutions in Ireland and the UK, in excess of government-insured levels, represents a material risk.
