Risks and Uncertainties [Abstract]
Significant Customers and Concentration of Credit Risk	Significant Customers & Concentration of Credit Risk We have a market concentration of revenue in both the automotive sector and financial & insurance sector. Revenue from the automotive industry accounted for approximately 14% and 17% of our consolidated revenue for the six months ended June 30, 2014 and 2013, respectively. Revenue from the financial & insurance industry accounted for approximately 15% and 9% of our consolidated revenue for the six months ended June 30, 2014 and 2013, respectively. In prior periods, we also had a concentration of revenue from the United States government. For the six months ended June 30, 2014 and 2013, sales to the United States government and its agencies represented approximately 9% and 10%, 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 consolidated revenue for the six months ended June 30, 2014 and 2013. As of June 30, 2014, billed and unbilled accounts receivable from a single financial services customer totaled $20.9 million, or 14%, of our consolidated accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts balances.

This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
