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 deferred tax assets and other real estate, other-than-temporary impairments of securities, and the fair value of financial instruments.</p>
