Fair Value Measurements

6 Months Ended

Jun. 30, 2023

The Corporation uses fair value measurements to record fair value adjustments on certain assets and liabilities and to determine fair value disclosures. Items recorded at fair value on a recurring basis include securities available for sale, mortgage loans held for sale and derivatives. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as collateral dependent individually analyzed loans, OREO and mortgage servicing rights. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets.

Fair value is a market-based measurement, not an entity-specific measurement. Fair value measurements are determined based on the assumptions the market participants would use in pricing the asset or liability. In addition, GAAP specifies a hierarchy of valuation techniques based on whether the types of valuation information, or “inputs”, are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Corporation’s market assumptions. These two types of inputs have created the following fair value hierarchy:

•Level 1 – Quoted prices for identical assets or liabilities in active markets.

•Level 2 – Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

•Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable in the markets and which reflect the Corporation’s market assumptions.

Fair Value Option Election

GAAP allows for the irrevocable option to elect fair value accounting for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. The Corporation has elected the fair value option for mortgage loans held for sale to better match changes in fair value of the loans with changes in the fair value of the forward sale commitment contracts used to economically hedge them.

The following table presents a summary of mortgage loans held for sale accounted for under the fair value option:


(Dollars in thousands)	June 30, 2023	December 31, 2022
Aggregate fair value	$20,872	$8,987
Aggregate principal balance	20,727	8,860
Difference between fair value and principal balance	$145	$127

Changes in fair value of mortgage loans held for sale accounted for under the fair value option election are included in mortgage banking revenues in the Unaudited Consolidated Statements of Income. Changes in fair value amounted to a decrease of $6 thousand to mortgage banking revenues for the three months ended June 30, 2023 and an increase of

$18 thousand for the six months ended June 30, 2023. This compared to an increase of $327 thousand to mortgage banking revenues for the three months ended June 30, 2022 and a decrease of $748 thousand for the six months ended June 30, 2022.

There were no mortgage loans held for sale 90 days or more past due as of June 30, 2023 and December 31, 2022.

Valuation Techniques

Debt Securities

Available for sale debt securities are recorded at fair value on a recurring basis. When available, the Corporation uses quoted market prices to determine the fair value of debt securities; such items are classified as Level 1. There were no Level 1 debt securities held at June 30, 2023 and December 31, 2022.

Level 2 debt securities are traded less frequently than exchange-traded instruments. The fair value of these securities is determined using matrix pricing with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category includes obligations of U.S. government-sponsored enterprises, including mortgage-backed securities, individual name issuer trust preferred debt securities and corporate bonds.

Debt securities not actively traded whose fair value is determined through the use of cash flows utilizing inputs that are unobservable are classified as Level 3. There were no Level 3 debt securities held at June 30, 2023 and December 31, 2022.

Mortgage Loans Held for Sale

The Corporation has elected the fair value option for mortgage loans held for sale. The fair value is estimated based on current market prices for similar loans in the secondary market and therefore are classified as Level 2 assets.

Collateral Dependent Individually Analyzed Loans

Collateral dependent individually analyzed loans are valued based upon the lower of amortized cost or fair value. Fair value is determined based on the appraised value of the underlying collateral. Such collateral primarily consists of real estate and, to a lesser extent, other business assets. For collateral dependent loans that are expected to be repaid substantially through the sale of the collateral, management adjusts the fair value for estimated costs to sell. Management may also adjust appraised values to reflect estimated market value declines or apply other discounts to appraised values resulting from its knowledge of the collateral. Internal valuations may be utilized to determine the fair value of other business assets. Collateral dependent individually analyzed loans are categorized as Level 3.

Derivatives

Interest rate derivative contracts are traded in over-the-counter markets where quoted market prices are not readily available. Fair value measurements are determined using independent valuation software, which utilizes the present value of future cash flows discounted using market observable inputs such as forward rate assumptions. The Corporation evaluates the credit risk of its counterparties, as well as that of the Corporation. Accordingly, factors such as the likelihood of default by the Corporation and its counterparties, its net exposures and remaining contractual life are considered in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of collateral securing the position, if any. The Corporation has determined that the majority of the inputs used to value its derivative positions fall within Level 2 of the fair value hierarchy. However, the credit valuation adjustments utilize Level 3 inputs. As of June 30, 2023 and December 31, 2022, the Corporation has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Corporation has classified its derivative valuations in their entirety as Level 2.

Fair value measurements of forward loan commitments (interest rate lock commitments and forward sale commitments) are primarily based on current market prices for similar assets in the secondary market for mortgage loans and therefore are classified as Level 2 assets. The fair value of interest rate lock commitments is also dependent on the ultimate closing of the loans. Pull-through rates are based on the Corporation’s historical data and reflect the Corporation’s best estimate of the likelihood that a commitment will result in a closed loan. Although the pull-through rates are Level 3 inputs, the Corporation has assessed the significance of the impact of pull-through rates on the overall valuation of its interest rate lock commitments and has determined that they are not significant to the overall valuation. As a result, the Corporation has classified its interest rate lock commitments as Level 2.

Items for which Fair Value is Only Disclosed

The estimated fair values and related carrying amounts for financial instruments for which fair value is only disclosed are presented below as of the periods indicated. The tables exclude financial instruments for which the carrying value approximates fair value such as cash and cash equivalents, FHLB stock, accrued interest receivable, BOLI, non-maturity deposits and accrued interest payable.
