Actual results could differ from those estimates.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for credit and foreclosed real estate losses, management obtains independent appraisals for significant properties.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Substantially all of the Bank’s loan portfolio consists of loans in its market area. Accordingly, the ultimate collectability of a substantial portion of the Bank’s loan portfolio and the recovery of a substantial portion of the carrying amount of foreclosed real estate are susceptible to changes in local market conditions. The regional economy is diverse, but influenced to an extent by the manufacturing and agricultural segments.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">While management uses available information to recognize loan and foreclosed real estate losses, future additions to the allowances <em style="font: inherit;"> may </em>be necessary based on changes in local economic conditions. In addition, regulatory agencies, as a part of their routine examination process, periodically review the Bank’s allowances for loan and foreclosed real estate losses. Such agencies <em style="font: inherit;"> may </em>require the Bank to recognize additions to the allowances based on their judgments about information available to them at the time of their examinations. Because of these factors, it is reasonably possible that the allowances for loan and foreclosed real estate losses <em style="font: inherit;"> may </em>change materially in the near term.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The Company seeks strategies that minimize the tax effect of implementing their business strategies. As such, judgments are made regarding the ultimate consequence of long-term tax planning strategies, including the likelihood of future recognition of deferred tax benefits. The Company’s tax returns are subject to examination by both Federal and State authorities. Such examinations <em style="font: inherit;"> may </em>result in the assessment of additional taxes, interest and penalties. As a result, the ultimate outcome, and the corresponding financial statement impact, can be difficult to predict with accuracy.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Accounting for pension benefits, costs and related liabilities are developed using actuarial valuations. These valuations include key assumptions determined by management, including the discount rate and expected long-term rate of return on plan assets. Material changes in pension costs <em style="font: inherit;"> may </em>occur in the future due to changes in these assumptions.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p>
