Unbilled contract receivables represent revenue recognized on construction-type or production-type contracts that arise based on performance attainment which, by contract, though appropriately recognized, cannot be billed to the customer as of the balance sheet date. We expect to bill and collect substantially all of the June 30, 2011 unbilled contract receivables during the next twelve months as billing milestones are completed or units are delivered.

Our outstanding accounts receivable balance, including both trade and unbilled contract receivables from the U.S. Government, was $928 and $806 as of June 30, 2011 and December 31, 2010, respectively.
