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, other-than-temporary impairments of securities, evaluation of impairment of goodwill, and pension obligations.</div> <div style=" font-family:'Times New Roman', Times, serif;font-size:10pt;margin:0pt;text-align:justify;text-indent:18pt;">Changing economic conditions, adverse economic prospects for borrowers, as well as regulatory agency action as a result of examination, could cause NBB to recognize additions to the allowance for loan losses and <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"> may </div>also affect the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans.</div></div></div></div></div></div></div>
