Reconciliation of Assets on Recurring Basis Using Significant Unobservable Inputs

All assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) were valued using pricing models and discounted cash flow methodologies, as of December 31, 2019, 2018 and 2017. This reconciliation is presented in the table below for the periods indicated:

	2019			2018			2017

Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation [Table Text Block]

The following table sets forth certain unobservable inputs regarding the Company's financial instruments that are classified as Level 3 as of December 31st of the years indicated:

Valuation Technique	Fair Value				Unobservable Inputs	Range		Weighted Average
	2019		2018			2019	2018	2019	2018
	(Dollars in thousands)
Discounted cash flow methodology
Pooled trust preferred securities	$	1,114	$	1,329	Cumulative prepayment	0% - 57%	0% - 59%	2.6%	2.1%
					Cumulative default	2% - 100%	5% - 100%	13.5%	16.2%
					Loss given default	85% - 100%	85% - 100%	93.6%	94.8%
					Cure given default	0% - 75%	0% - 75%	60.9%	60.9%
Appraisals of collateral (1)
Collateral dependent impaired loans	$	25,515	$	29,109

(1)

Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

(a) The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.

(b) Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes collateral dependent impaired loans, which are deemed to be marked to fair value on a nonrecurring basis.

(c) FHLB stock has no quoted market value and is carried at cost, therefore the carrying amount approximates fair value.

(d) Cash surrender value of life insurance is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore carrying amount approximates fair value.

(e) Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.

(f) Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.

(g)

Fair value was determined based upon market prices of securities with similar terms and maturities.
