In 2012, The Company refined its methodology used in estimating the amount of the Allowance for Loan and Lease Losses. Management has been proactive in identifying problem loans, assessing exposure, and providing sufficient reserves to cover the exposures. The Allowance for Loan and Lease Losses was increased in anticipation of identified exposures resulting in confirmed losses. When losses were confirmed, they were promptly charged off. As a result, losses over the last three years have been very high. During this time, newer loans granted were made subject to higher underwriting standards and more conservative appraisals. Because of the prompt recognition of losses that drove the excessive charge-off history, management now believes the remaining losses incurred in the current portfolio, including newer loans made, will be less than unadjusted loss history factors will suggest. Considering the major losses taken, along with organizational and staffing changes, the validity of qualitative factors in determining adjustments of loss history needed to be reviewed. Recognizing the importance of credit administration and the role of personnel involved in granting, approving, administering, monitoring, and collecting loans, management concluded that greater weight should be placed on factors associated with those activities. The effect of these changes on the ALLL resulted in a reduction in the ALLL estimate of $1,496. Management believes the adjustments made will result in a better estimation of losses incurred in the portfolio. The Company determines its individual reserves during its quarterly review of substandard loans. This process involves reviewing all loans with a risk grade of 6 or below and an outstanding balance of $50,000 or more. At March 31, 2012 and 2011, impaired loans totaling $869 and $824 were below the $50,000 review threshold and were not individually reviewed for impairment. Those loans were subject to the bank's general loan loss reserve methodology and are included in the "Collectively Evaluated for Impairment" column of the following tables. Since not all loans in the substandard category are considered impaired, this quarterly assessment often results in the identification of individual reserves which are placed against certain loans as part of management's allowance for loan loss calculation. The total of these loans and the related reserves are presented in the column titled "Substandard Loans Individually Reviewed for Impairment" in the following tables. The following tables present breakdowns of the allowance for loan losses, segregated by impairment methodology for March 31, 2012 and 2011:
