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
August 31, 2017,
and
November 30, 2016,
the carrying amount approximated fair value for cash, accounts receivable, 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 Company’s installment term loans payable also approximate recorded value because the interest rates charged under the loan terms are
not
substantially different than current interest rates.
