We have a market concentration of revenue in the automotive sector and in prior years had a concentration of revenue from General Motors Corporation and its affiliates and successor (“General Motors”). Revenue from the automotive industry accounted for approximately 14% and 18% of our consolidated revenue for the three months ended March 31, 2012 and 2011, respectively, and revenue from General Motors accounted for approximately 7% and 11%, respectively, of our consolidated revenue for the three months ended March 31, 2012 and 2011. No other customer accounted for more than 10% of our revenue in the first quarter of 2012 or accounts receivable as of March 31, 2012.

For the three months ended March 31, 2012 and 2011, sales to the United States government and its agencies represented approximately 14% and 19%, 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.
