Loans and Allowance for Loan Losses. Real estate or other assets secure most loans. The majority of loans have been made to individuals and businesses in the Company’s market of South Louisiana. Customers are dependent on the condition of the local economy for their livelihoods and servicing their loan obligations. The Company does not have any significant concentrations in any one industry or individual customer. </font></div></div>

Actual results could differ from those estimates, and such differences could be material.</font></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses. While management uses available information to recognize losses on loans, future additions to the allowance 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 allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance 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 allowance for loan losses may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.</font></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Other estimates that are susceptible to significant change in the near term relate to the determination of other-than-temporary impairments of securities and the fair value of financial instruments.</font></div></div>
