Since the Company's receivables are primarily with the U.S. government, the Company does not have exposure to a material credit risk. The Company manages its credit risk related to derivatives through the use of multiple counterparties with high credit standards</font></div></div>

Management evaluates these estimates and assumptions on an ongoing basis, including those relating to estimated profitability of long-term contracts, indirect billing rates, allowances for doubtful accounts, inventories, fair value and impairment of intangible assets and goodwill, income taxes, pension benefits, stock-based compensation expense and contingencies. These estimates have been prepared by management on the basis of the most current and best available information; however, actual results could differ materially from those estimates.</font></div></div>
