[1] The method of valuation approach for the loans evaluated for an allowance for credit losses on an individual loan basis and also for other real estate owned was the market approach based upon appraisals of the underlying collateral by external appraisers, reduced by 7% to 10% for estimated selling costs. Intangible assets are valued based upon internal analyses.

[2] Non-SBA CRE-floating are floating rate non-SBA loans, the vast majority of which are secured by multi-family properties (apartments). These are bridge loans designed to provide owners time and funding for property improvements and are generally valued internally using discounted cash flow analysis. The discount rate for the vast majority of these loans was based upon current origination rates for similar loans. Deterioration in loan performance or other credit weaknesses could result in fair value ranges which would be dependent upon potential buyers’ tolerance for such weaknesses and are difficult to estimate. Certain of these loans are fair valued by a third party, based upon discounting at market rates for similar loans.

[3] Insurance liquidating trust preferred security is a single debenture which is valued using discounted cash flow analysis. The discount rate used is based on the market rate on comparable relatively illiquid instruments and credit analysis. A change in the liquidating trust’s ability to repay the note, or an increase in interest rates, particularly for privately placed debentures, would affect the discount rate and thus the valuation. As a single security, the weighted average rate shown is the actual rate applied to the security.

[4] For other real estate owned, fair value is based upon appraisals of the underlying collateral by third party appraisers, reduced by 7% to 10% for estimated selling costs. Such appraisals reflect estimates of amounts realizable upon property sales based on the sale of comparable properties and other factors. Actual sales prices may vary based upon the identification of potential purchasers, changing conditions in local real estate markets and the level of interest rates required to finance purchases.
