Fair Value Measured on a Recurring Basis

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following tables set forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis. There were no transfers between any of the levels for the periods presented.

Significant Unobservable Inputs, Fair Value Valuation Techniques

The Company determines fair values based on quoted market values, where available, estimates of present values, or other valuation techniques. Those techniques are significantly affected by the assumptions used, including, but not limited to, the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in immediate settlement of the instrument. The significant unobservable inputs used in the determination of fair value of assets classified as Level 3 on a recurring or non-recurring basis are as follows:


									Significant
									Unobservable Input
		Fair Value at							Range
(000's omitted, except per loan data)		June 30, 2021			Valuation Technique		Significant Unobservable Inputs		(Weighted Average)
Impaired loans		$	21,330		Fair value of collateral		Estimated cost of disposal/market adjustment			9.0% - 78.7% (53.8%)
Other real estate owned			879		Fair value of collateral		Estimated cost of disposal/market adjustment			9.0% - 51.1% (34.5%)
Commitments to originate real estate loans for sale			130		Discounted cash flow		Embedded servicing value			1.0	%
Mortgage servicing rights			697		Discounted cash flow		Weighted average constant prepayment rate			16.9% - 49.1% (21.8%)

							Adequate compensation		$	7/loan
