[1] 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 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. At September 30, 2022, these loans were fair valued by a third party, based upon discounting at market rates for similar loans.

[2] Subordinated debentures are comprised of two subordinated notes issued by the Company, maturing in 2038 with a floating rate of 3-month LIBOR plus 3.25%. These notes are valued using discounted cash flow analysis. The discount rate is based on the market rate for comparable relatively illiquid instruments. Changes in those market rates, or the credit of the Company could result in changes in valuation.

[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.
