Business Segment And Geographic Area Information

Business Segment and Geographic Area Information

We have one reportable segment. We deliver information technology and technical services solutions under contracts with the U.S. government, state and local governments and commercial customers. Our federal government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. Revenues from the U.S. government under prime contracts and subcontracts were approximately 99.2%, 98.7% and 98.3% for the years ended December 31, 2011, 2010 and 2009, respectively. There were no sales to any customers within a single country (except for the United States) where the sales accounted for 10% or more of total revenues. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed. Substantially all assets of continuing operations were held in the United States for the years ended December 31, 2011, 2010 and 2009. Revenues by geographic customer and the related percentages of total revenues for the years ended December 31, 2011, 2010 and 2009, were as follows (dollars in thousands):
