Significant Customers & Concentration of Credit Risk

(3) Significant Customers & Concentration of Credit Risk

We have a market concentration of revenue in the automotive sector. Revenue from the automotive industry accounted for approximately 17% of our consolidated revenue for both nine-month periods ended September 30, 2012 and 2011. We also have a concentration of revenue from the United States government. For the nine months ended September 30, 2012 and 2011, sales to the United States government and its agencies represented approximately 13% and 15%, respectively, of our consolidated revenue. Revenue was derived from many separate contracts with a variety of government agencies that are regarded by us as separate customers. No single customer accounted for more than 10% of our revenue for the nine months ended September 30, 2012 or accounts receivable as of September 30, 2012.
