[1] Loans without a specific allowance reserve have not been individually evaluated for impairment, but have been included in pools of homogeneous loans for evaluation of related allowance reserves.

[2] Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals to establish realizable value. These analyses may identify a specific impairment amount needed or may conclude that no reserve is needed. Any specific impairment that is identified is included in the category’s "Related Allowance" column.
