Material estimates that are particularly susceptible to significant change relate to the fair value of available-for-sale securities, the determination of the allowance for losses on loans and the valuation for foreclosed assets.</span> While management uses its best judgement and reviews estimates and related assumptions periodically, <span style="letter-spacing:0.2pt;">actual results could differ from those estimates.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;min-height:11.5pt;text-align:justify;margin:0pt;"><span style="letter-spacing:0.2pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;min-height:11.5pt;text-align:justify;margin:0pt;"><span style="letter-spacing:0.2pt;">A large majority of the Company’s investment securities are classified as available-for-sale and reported at fair value with changes in unrealized gains and losses, net of tax, included in other comprehensive income. The fair value of investment securities are highly sensitive to changes in market interest rates and the current and projected financial condition of the related issuer. Declines in fair value of available-for-sale securities may be realized as losses in the income statement if they are deemed to be other-than-temporary based on management’s analysis of the individual securities. </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;min-height:11.5pt;text-align:justify;margin:0pt;"><span style="letter-spacing:0.2pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;min-height:11.5pt;text-align:justify;margin:0pt;"><span style="letter-spacing:0.2pt;">A substantial portion of the Company’s loans and foreclosed assets are secured by real estate in local markets which are largely rural and rely heavily upon agriculture and the oil and gas industry. Accordingly, the ultimate collectability of a substantial portion of the Company’s loan portfolio and the recovery of the carrying amount of foreclosed assets are susceptible to changes in local market conditions.</span> <span style="letter-spacing:0.2pt;">While management uses available information to recognize losses on loans and foreclosed assets, further reductions in the carrying amount of loans and foreclosed assets 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 Company’s estimated losses on loans and foreclosed assets. While management is responsible for the establishment of the allowance for loan losses and for adjusting such allowance through provisions for loan losses, as a result of such regulatory reviews management may determine that an increase or decrease in the allowance or provision for loan losses may be necessary. Because of these factors, it is reasonably possible that the estimated losses on loans and foreclosed assets may change materially in the near-term. However, the amount of the change that is reasonably possible cannot be estimated.</span></p>
