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

[2] Appraisals may be adjusted downwards by management for qualitative factors such as economic conditions. 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.

[3] Appraisals are adjusted downwards by management for qualitative factors such as the estimated costs to liquidate the collateral.
