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;margin:0pt;">Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the valuation of investment securities, the determination and the amount of impairment in the securities portfolios, and the related realization of the deferred tax assets related to the allowance for loan losses, other-than-temporary impairment on and valuations of investment securities.</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;margin:0pt;">In connection with the determination of the allowance for loan losses, management generally obtains independent appraisals for significant properties, utilizes historical loss factors and applies judgement to determine qualitative factor adjustments. While management uses available information to recognize losses on loans, further reductions in the carrying amounts of loans <em style="font: inherit;"> may </em>be necessary based on changes in economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans. Such agencies <em style="font: inherit;"> may </em>require the Company 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 <em style="font: inherit;"> may </em>change materially in the near-term. However, the amount of the change that is reasonably possible cannot be estimated.</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;margin:0pt;">The Company’s investment securities are comprised of a variety of financial instruments. The fair values of the securities are subject to various risks including changes in the interest rate environment and general economic conditions including illiquid conditions in the capital markets. Due to the increased level of these risks and their potential impact on the fair values of the securities, it is possible that the amounts reported in the accompanying financial statements could materially change in the near-term. Any credit-related impairment is included as a component of non-interest income in the consolidated income statements while non-credit-related impairment is charged to other comprehensive income, net of tax.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p>

Although the Company has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on the economic sector in which the Company operates.
