For all loan classes, loan losses are charged against the ALL when management believes the loan balance is uncollectible or in accordance with federal guidelines. Subsequent recoveries, if any, are credited to the ALL.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The ALL is maintained at a level believed by management to be appropriate to absorb probable credit losses inherent in the loan portfolio as of the balance sheet date. The amount of the ALL is based on management's periodic evaluation of the collectability of the loan portfolio, including the nature, volume and risk characteristics of the portfolio, credit concentrations, trends in historical loss experience, estimated value of any underlying collateral, specific impaired loans and economic conditions. There was no change to the methodology used to estimate the ALL during the third quarter of 2021. While management uses available information to recognize losses on loans, future additions to the ALL may be necessary based on changes in economic conditions or other relevant factors.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In addition, various regulatory agencies, as an integral part of their examination process, regularly review the Company's ALL. Such agencies may require the Company to recognize additions to the ALL, with a corresponding charge to earnings, based on their judgments about information available to them at the time of their examination, which may not be currently available to management.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The ALL consists of specific, general and unallocated components. The specific component relates to the loans that are classified as impaired. Loans are evaluated for impairment and may be classified as impaired when management believes it is probable that the Company will not collect all the contractual interest and principal payments as scheduled in the loan agreement. Impaired loans may also include troubled loans that are restructured. A TDR occurs when the Company, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that would otherwise not be granted. A TDR classification may result from the transfer of assets to the Company in partial satisfaction of a troubled loan, a modification of a loan's terms (such as reduction of stated interest rates below market rates, extension of maturity that does not conform to the Company's policies, reduction of the face amount of the loan, reduction of accrued interest, or reduction or deferment of loan payments), or a combination. A specific reserve amount is allocated to the ALL for individual loans that have been classified as impaired based on management's estimate of the fair value of the collateral for collateral dependent loans, an observable market price, or the present value of anticipated future cash flows. The Company accounts for the change in present value attributable to the passage of time in the loan loss reserve. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer, real estate or small balance commercial loans for impairment evaluation, unless such loans are subject to a restructuring agreement or have been identified as impaired as part of a larger customer relationship. Based on an evaluation of the Company's historical loss experience on substandard commercial loans, management has established the commercial loan threshold for individual impairment evaluation as commercial loan relationships with aggregate balances greater than $500 thousand.</span></div><div style="text-align:justify"><span><br/></span></div><div style="margin-bottom:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The general component represents the level of ALL allocable to each loan portfolio segment with similar risk characteristics and is determined based on historical loss experience, adjusted for qualitative factors, for each class of loan. Management deems a five year average to be an appropriate time frame on which to base historical losses for each portfolio segment. Qualitative factors considered include underwriting, economic and market conditions, portfolio composition, collateral values, delinquencies, lender experience and legal issues. The qualitative factors are determined based on the various risk characteristics of each portfolio segment.
