Note 13 – Significant Risks and Uncertainties


Cash and Cash Equivalents


The Company places most of its temporary cash investments with financial institutions, which from time to time may exceed the Federal Deposit Insurance Corporation limit. The amount at risk at December 31, 2013 and at December 31, 2012 was $9,834,765 and $4,397,166, respectively.


Sales Concentrations


Revenue to a single customer in any one year can exceed 10.0% of our total sales. In fiscal year 2013 one customer represented 23.7% of our annual revenues and in 2012 another customer represented 16.6% of our annual revenues, respectively. We are not dependent on any single customer, and the loss of any key customer would have to be replaced by others, as we have previously, or our inability to do so may have a material adverse effect on our business and financial condition.


Export sales to unaffiliated customers represented approximately 27.3% and 24.4% of sales for the years ended December 31, 2013 and 2012, respectively. Export sales in both 2013 and 2012 were primarily to customers in Europe and Asia. All contracts are denominated in U.S. dollars. The Company does not enter into any foreign exchange contracts.
