Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#231f20;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for changes in underwriting standards, portfolio mix, delinquency level, changes in environmental conditions, unemployment rates, risk classifications and collateral values. The Company separately assigns allocations for substandard and special mention commercial and agricultural credits as well as other categories of loans based on migration analysis techniques. The migration analysis factors are calculated using a transition matrix to determine the likelihood of a customer's asset quality rating migrating from its current rating to any other rating.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#231f20;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The allowance for credit losses is measured on a collective (pooled) basis when similar risk characteristics exist.

Most commercial loans are secured by accounts receivable, inventory and equipment. If cash flow from business operations is reduced, the borrower's ability to repay the loan may diminish, and over time, it may also be difficult to substantiate current value of inventory and equipment.

Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy.
