(13) CONCENTRATIONS

Concentration of credit risk

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. The Company places its cash with high credit quality financial institutions. The Company maintains its cash in bank deposit accounts, which, at times, exceed federally insured limits. The Company has not experienced any losses in such accounts through December 31, 2014.

At December 31, 2014 and 2013, approximately 48% and 44%, respectively, of the balance of accounts receivable was due from the Company’s largest customer. In addition at December 31, 2014 and 2013, separate customers accounted for 14% and 14%, respectively, of the accounts receivable balance. No other customer account balances were more that 10% of accounts receivable at December 31, 2014 or 2013. If one or more of the Company’s significant customers were to become insolvent or were otherwise unable to pay for the products provided, it would have a material adverse effect on the Company’s financial condition and results of operations.

Concentration of supplier

The Company’s logistics partners arrange for production of its raw materials related to the InvisibleShield film products primarily from one source. Management is aware of similar raw materials that would be available from other sources if required and has current plans to immediately engage such resources if necessary. A change in supplier, however, could cause a delay in manufacturing and a possible loss of sales, which could adversely affect operating results.

Concentration of sales

For the years ended December 31, 2014, 2013, and 2012, one customer accounted for 30%, 26%, and 32%, respectively, of the Company’s sales; during the same periods, a second customer accounted for 11%, 18%, and 11%, respectively, of sales; and a third customer accounted for 11%, 6%, and 7%, respectively, of sales. No other customer account balances were more that 10% of sales during 2014. If the Company loses one or more of the Company’s significant customers, it would have a material adverse effect on the Company’s financial condition and results of operations.

The percentage of sales by geographic region for the years ended December 31, 2014, 2013 and 2012 was approximately:

At December 31, 2014 and 2013, net assets located overseas in Shannon, Ireland totaled $8,050 and $8,695, respectively.
