Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of other real estate owned and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and business combination elements (Day 1 and Day 2 Valuation).</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="margin-bottom:12pt;visibility:hidden;"></span></p>
