Note 7 - Concentrations of credit risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents with high-credit quality financial institutions. At July 31, 2015, the Company had cash and cash equivalent balances in excess of Federally insured limits in the amount of approximately $6.7 million.

One customer accounted for approximately 18% and 33% of the Company’s net sales for the nine month periods ended July 31, 2015 and 2014, respectively. This same customer accounted for approximately 16% and 34% of the Company’s net sales for the three months ended July 31, 2015 and 2014, respectively. At July 31, 2015 and October 31, 2014, this customer’s account receivable balance accounted for approximately 28% and 34%, respectively, of the Company’s total net accounts receivable balances. Although this customer has been an on-going major customer of the Company continuously during the past 15 years, the written agreements with this customer do not have any minimum purchase obligations and the customer could stop buying the Company’s products at any time and for any reason. A reduction, delay or cancellation of orders from this customer or the loss of this customer could significantly reduce the Company’s future revenues and profits.

There was no product line that was significant for the three and nine months ended July 31, 2015. Sales of one product line accounted for $388,000 or 7% of net sales and $1.8 million or 11% of net sales for the three and nine months ended July 31, 2014, respectively.
