[1] Fair value is generally determined through independent appraisals of the underlying collateral, which generally includes various level 3 inputs which are not observable.

[2] Includes qualitative adjustments by management and estimated liquidation expenses.

[3] Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received, or age of the appraisal.
