These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the provision for credit losses, valuation of investments, goodwill, intangible assets, other long-lived assets, tax accruals and other liabilities. In addition, estimates are used in revenue recognition, income tax expense, performance and share-based compensation, depreciation and amortization, litigation matters and other matters, as well as in the valuation of contingent consideration and noncontrolling interests resulting from business combination transactions. Management believes its use of estimates in the financial statements to be reasonable.</span></div><div style="margin-top:6.6pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and as such these estimates may ultimately differ from actual results. Changes in estimates resulting from weakness in the economic environment or other factors beyond the Company’s control could be material and would be reflected in the Company’s financial statements in future periods.</span></div>
