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, 2012 and at December 31, 2011 was $4,397,166 and $3,859,843, respectively.

Sales Concentrations

Revenue to a single customer in any one year can exceed 10.0% of our total sales.  In fiscal years 2012 and 2011 one customer represented 16.6% and 43.2% 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 24.4% and 12% of sales for the years ended December 31, 2012 and 2011, respectively. Export sales in both 2012 and 2011 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.
