Once received, a member of the Loan Administration Department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. On a quarterly basis, the Company compares the actual selling price of similar collateral that has been liquidated to the most recent appraised value for unsold properties to determine what additional adjustment, if any, should be made to the appraisal value to arrive at fair value. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available.
