CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

NOTE 2. CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and accounts receivable. With regard to cash, we maintain our excess cash balances in checking accounts at two high-credit quality financial institutions. These accounts may at times exceed federally insured limits. We grant credit to customers in the normal course of business and do not require collateral on our accounts receivable.

Our largest customer has two divisions that together accounted for 10% or more of our net sales during the year ended December 31, 2017 and 2016. One division accounted for approximately 23.5% and 20.0% of net sales for the years ended December 31, 2017 and 2016, respectively. The second division accounted for approximately 1.4% and 3.8% of net sales for the years ended December 31, 2017 and 2016, respectively. Together they accounted for approximately for 24.9% and 23.8% of net sales for the years ended December 31, 2017 and 2016, respectively. Accounts receivable from the customer at December 31, 2017 and 2016 represented 16.4% and 13.6% of our total accounts receivable, respectively.
