Significant Customers And Concentration Of Credit Risk

10. SIGNIFICANT CUSTOMERS AND CONCENTRATION OF CREDIT RISK

Royalty income from Econolite comprised 50%, 43% and 40% of revenue in the years ended December 31, 2012, 2011 and 2010, respectively. Accounts receivable from Econolite were $2.6 million and $4.3 million at December 31, 2012 and 2011, respectively. Major disruptions in the manufacturing and distribution of our products by Econolite or the inability of Econolite to make payments on its accounts receivable with us could have a material adverse effect on our business, financial condition and results of operations. Econolite was the only customer that comprised more than 10% of accounts receivable as of December 31, 2012. During the period from April 2011 through August 2012, the Chief Executive Officer of the parent company of Econolite served on our Board of Directors.
