Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for credit losses; estimated cash flows related to PCI loans; fair value determinations related to acquisitions and other assets and liabilities carried at fair value; and accounting for income taxes. Although management believes these estimates to be reasonably accurate, actual amounts may differ. In the opinion of management, all adjustments considered necessary have been reflected in the Unaudited Consolidated Financial Statements.</font></div></div>
