The Company bases its estimates on assumptions regarding historical experience, currently available information, and anticipated developments that it believes are reasonable and appropriate. However, because the use of estimates involves an inherent degree of uncertainty, actual results could differ from those estimates. Estimates are used for, but not limited to, contracts accounted for using the percentage-of-completion method, cash flows used in the evaluation of impairment of goodwill and other long-lived assets, reserves for uncertain tax positions, valuation allowances on deferred tax assets, loss accruals for litigation, and obligations related to our pension plans. In the opinion of the Company's management, the accompanying financial statements contain all adjustments necessary, including those of a normal recurring nature, to fairly present the financial statements.</span></div>
