Fair Value Measurements

6 Months Ended

Jun. 30, 2022

The Company uses fair value measurements to record fair value adjustments to certain financial and nonfinancial assets and liabilities and to determine fair value disclosures. Various financial instruments such as available for sale debt securities, equity securities, trading debt securities, certain investments relating to private equity activities, and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets and liabilities on a nonrecurring basis, such as mortgage servicing rights and certain other investment securities. These nonrecurring fair value adjustments typically involve lower of cost or fair value accounting or write-downs of individual assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. For accounting disclosure purposes, a three-level valuation hierarchy of fair value measurements has been established. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

•Level 1 – inputs to the valuation methodology are quoted prices for identical assets or liabilities in active markets.

•Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and inputs that are observable for the assets or liabilities, either directly or indirectly (such as interest rates, yield curves, and prepayment speeds).

•Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value. These may be internally developed, using the Company’s best information and assumptions that a market participant would consider.

The valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis are described in the Fair Value Measurements note in the Company's 2021 Annual Report on Form 10-K. There have been no significant changes in these methodologies since then.

Instruments Measured at Fair Value on a Recurring Basis

The table below presents the June 30, 2022 and December 31, 2021 carrying values of assets and liabilities measured at fair value on a recurring basis. There were no transfers among levels during the first six months of 2022 or the year ended December 31, 2021.

Level 3 Inputs

The Company's significant Level 3 measurements, which employ unobservable inputs that are readily quantifiable, pertain to auction rate securities (ARS), investments in portfolio concerns held by the Company's private equity subsidiaries, and held for sale residential mortgage loan commitments. ARS are included in state and municipal securities and totaled $1.8 million at June 30, 2022, while private equity investments, included in other securities, totaled $161.8 million.

Information about these inputs is presented in the table below.


Quantitative Information about Level 3 Fair Value Measurements						Weighted
	Valuation Technique	Unobservable Input	Range			Average*
Auction rate securities	Discounted cash flow	Estimated market recovery period			5 years	5 years
		Estimated market rate	4.6%	-	5.3%	5.0%
Private equity investments	Market comparable companies	EBITDA multiple	4.0	-	7.0	5.5
Mortgage loan commitments	Discounted cash flow	Probability of funding	67.2%	-	100.0%	88.6%
		Embedded servicing value	.9%	-	1.5%	1.2%

* Unobservable inputs were weighted by the relative fair value of the instruments.
