[1] Fair value is generally determined through independent appraisals of the underlying collateral, which include Level 3 inputs that are not identifiable.

[2] Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses.

[3] There is a lack of transactional data in this market place for the non-guaranteed portion of SBA loans.

[4] The range and weighted average of qualitative factors such as economic conditions and estimated liquidation expenses are presented as a percent of the appraised value.
