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, 2021 and 2020, significant amounts of cash and 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 January 31, 2021 and 2020 consisted solely of certificates of deposit purchased from Bank of America (the “Bank”) with weighted average initial maturities of 292 days and 165 days, respectively (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 which approximates fair value. The total carrying value amounts as of January 31, 2021 and 2020 included accrued interest of $0.1 million and $0.5 million, respectively. Interest income is recorded when earned and is included in other income. As of January 31, 2021 and 2020, the weighted average annual interest rates of the CDs were 0.2% and 1.8%, respectively. In addition, the Company has a substantial portion of its cash on deposit in the US at the Bank in excess of federally insured limits. Management does not believe that the combined amount of the CD investments and the cash deposited with the Bank represents a material risk. The Company also maintain certain Euro-based bank accounts in Ireland and certain pound sterling-based bank accounts in the UK in support of the operations of APC.
