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