Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">The allowance for loan losses is evaluated on a regular basis by management and is based upon management's periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revisions as more information becomes available.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">The allowance consists of specific, historical and general components. The specific component relates to loans that are classified as either doubtful, substandard or special mention. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The historical component covers nonclassified loans and is based on historical loss experience adjusted for qualitative factors. A general component is maintained to cover uncertainties that could affect management's estimate of probable losses. &#160;The general component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and historical losses in the portfolio. &#160;General valuation allowances are based on internal and external qualitative risk factors such as (i) changes in the composition of the loan portfolio, (ii) the extent of loan concentrations within the portfolio, (iii) the effectiveness of the Company's lending policies, procedures and internal controls, (iv) the experience, ability and effectiveness of the Company's lending management and staff, and (v) national and local economics and business conditions.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">Loans identified as losses by management, internal loan review and/or regulatory agencies are charged off.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price or the fair value of the collateral if the loan is collateral dependent.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">A significant portion of the Company's impaired loans are deemed to be collateral dependent. &#160;Management therefore measures impairment on these loans based on the fair value of the collateral. &#160;Collateral values are determined based on appraisals performed by qualified licensed appraisers hired by the Company or by senior members of the Company's credit administration staff. &#160;The decision whether or not to obtain an external third-party appraisal usually depends on the type of property being evaluated. &#160;External appraisals are usually obtained on more complex, income producing properties such as hotels, shopping centers and businesses. &#160;Less complex properties such as residential lots, farm land and single family houses may be evaluated internally by senior credit administration staff.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">When the Company does obtain appraisals from external third-parties, the values utilized in the impairment calculation are "as is" or current market values. &#160;The appraisals, whether prepared internally or externally, may utilize a single valuation approach or a combination of approaches including the comparable sales, income and cost approach. &#160;Appraised amounts used in the impairment calculation are typically discounted 10 percent to account for selling and marketing costs, if the repayment of the loan is to come from the sale of the collateral. &#160;Although appraisals are not obtained each year on all impaired loans, the collateral values used in the impairment calculations are evaluated quarterly by management. &#160;Based on management's knowledge of the collateral and the current real estate market conditions, appraised values may be further discounted to reflect facts and circumstances known to management since the initial appraisal was performed.</div><div><br /></div><div style="text-align: justify; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;">Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. &#160;Such adjustments are typically significant and result in a level 3 classification of the inputs for determining fair value. &#160;Because of the high degree of judgment required in estimating the fair value of collateral underlying impaired loans and because of the relationship between fair value and general economic conditions, we consider the fair value of impaired loans to be highly sensitive to changes in market conditions.</div></div>falsefalsefalsenonnum:textBlockItemTypenaDisclosure of accounting policy for estimating the allowance for losses on loans and lease receivables.
