Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses and the valuation of mortgage servicing rights. Actual results could differ from those estimates.</p> <p style="margin-bottom:0pt;margin-top:6pt;text-align:justify;margin-left:7.08%;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The determination of the adequacy of the allowance for loan losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans, management obtains independent appraisals for significant collateral.</p> <p style="margin-bottom:0pt;margin-top:6pt;text-align:justify;margin-left:7.08%;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Bank’s loans are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Bank has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions in the agricultural industry.</p> <p style="margin-bottom:0pt;margin-top:6pt;text-align:justify;margin-left:7.08%;text-indent:0%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">While management uses available information to recognize losses on loans, further reductions in the carrying amounts of loans may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.</p>
