Actual results could vary from these estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for loan losses, income taxes, valuation and potential impairment of investment securities, other-than-temporary impairment (“OTTI”) of certain investment securities, as well as valuation of goodwill and other intangibles and their respective analysis of impairment.</font></div></div>
