In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Statements of Financial Condition, and income and expenses for the period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to fair value of securities available for sale, determination of the allowance for losses on loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, other-than-temporary impairment evaluations of securities, the valuation of deferred tax assets and the evaluation of goodwill and core deposit intangible impairment.</span></div>
