Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for loan losses, valuation of deferred tax assets, other-than-temporary impairment of debt securities and fair value of financial assets and liabilities.</span></p>

Although the Company’s loan portfolio is diversified, a substantial portion of the Company’s customers’ ability to honor their contracts is dependent upon the local business economy in which the Company operates. The concentration of credit by type of loan is set forth in Note 4 of the notes to consolidated financial statements.</p>
