[1] he specific reserve for collateral-dependent impaired loans was determined by any loan-to-value ratio in excess of 80% for consumer loans and any loan-to-value ratio in excess of 75% for commercial loans after applying any adjustments necessary to appraisals received to reflect changes in known factors, including, but not limited to, property condition and property location. For the December 31, 2014 valuation of fair value for the collateral-dependent impaired loans for which a specific reserve is allocated in accordance with Company policy, management calculated the reserve without consideration of loan-to-value ratios. Management calculated the estimated fair value of these impaired loans by reducing the appraised value of the collateral, adjusted for known factors, including, but not limited to, property condition, property location, by the estimated direct selling costs of the collateral. The amendment did not have a material impact on the ALL.
