Management estimates and assumptions also affect the reported amounts of revenues and expenses during the reporting period, and disclosure of contingent assets and liabilities at the reporting date. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Items subject to such estimates and assumptions include, but are not limited to: the allowance for credit losses; the valuation of deferred tax assets, goodwill, accrued expenses, and share based compensation; the allocation of goodwill and other assets across the reporting units (segments); and reserves for income tax uncertainties and other contingencies.</span></div>
