Disclosures About the Fair Value of Financial Instruments
 
The fair value of a financial instrument is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties. At
November 30, 2018,
and
November 30, 2017,
the carrying amount approximated fair value for cash, accounts receivable, net investment in sale-type leases, accounts payable, notes payable to bank, and other current and long-term liabilities. The carrying amounts approximate fair value because of the short maturity of these instruments. The fair value of the net investment in sales-type leases also approximates recorded value as that is based on discounting future cash flows at rates implicit in the lease. The rates implicit in the lease do
not
materially differ from current market rates. The fair value of the Company’s installment term loans payable also approximates recorded value because the interest rates charged under the loan terms are
not
substantially different than current interest rates.
