The Company assesses the adequacy of its allowance for loan losses prior to the end of each calendar quarter. The level of the allowance is based on management’s evaluation of the loan portfolios, past loan loss experience, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. Loan losses are charged off when management believes that the full collectability of the loan is unlikely. A loan may be partially charged-off after a “confirming event” has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely. Allocation of the allowance is made for specific loans, but the entire allowance is available for any loan that in management’s judgment deteriorates and is uncollectible. The portion of the reserve classified as qualitative factors, is management’s evaluation of potential future losses that would arise in the loan portfolio should management’s assumption about qualitative and environmental conditions materialize. This qualitative factor portion of the allowance for loan losses is based on management’s judgment regarding various external and internal factors including macroeconomic trends, management’s assessment of the Company’s loan growth prospects, and evaluations of internal risk controls.
