Areas of the consolidated financial statements where estimates may have the most significant effect include the provision for claimed indirect costs, valuation and expected lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for uncertain tax positions and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates.</span></div>
