Significant estimates and assumptions are inherent in the analysis and the measurement of management's best estimate of selling price ("BESP"), deferred tax assets, including the identification and quantification of income tax liabilities due to uncertain tax positions, the valuation and recoverability of goodwill and intangible assets, the assessment of potential loss from contingencies, the valuation of assets and liabilities acquired in a business combination, and the allowance for doubtful accounts. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. </font></div></div>
