[1] The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary. .
