Fair value estimates |
Fair value estimates | 9. Fair value estimates: ​ The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. ​ In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures,” fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including 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. In many cases, these values cannot be realized in immediate settlement of the instrument. ​ Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. ​ In accordance with GAAP, the Company groups its assets and liabilities generally measured at fair value into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued and the reliability of the assumptions used to determine fair value. These levels include: ​
| ● | Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.
| ● | Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
| ● | Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
An asset’s or liability’s placement in the fair value hierarchy is based on the lowest level of input that is significant to the fair value estimate. ​ At June 30, 2025, the Company owned 26 corporate debt securities with an aggregate amortized cost and fair value of $24.5 million and $24.4 million, respectively. At June 30, 2025, the market for two corporate debt securities was not active based on transaction criteria for similar instruments. The aggregate amortized cost and fair value for these two securities was $1.7 million and $1.9 million, respectively, at June 30, 2025. The Company obtained valuations for these securities from a third-party service provider that prepared the valuations using a market approach that involves identifying a population of transactions for similar instruments and incorporating an evaluation to capture credit risk associated with these bonds. Management takes measures to validate the service providers’ analysis and is actively involved in the valuation process, including reviewing the population and evaluation of credit risk. Management believes this approach to be a conservative approach as it takes into consideration securities that have longer maturities or longer call dates, issuers with smaller asset sizes, and securities with smaller issue amounts. These factors are typically considered to be factors that would add credit spread to a bond, thus resulting in a higher required yield. Management believes the valuation results from this market approach to be consistent with pricing and data for similar deals at June 30, 2025. The Company considers the inputs used in the market approach to be unobservable Level 3 inputs because, while inputs are based on actual transactions, the relative number of transactions in the population is small and subjective assumptions are used in determining and applying factors to incorporate credit spreads into the price determination. Management will continue to monitor the market for these securities to assess the market activity and the availability of observable inputs and will continue to apply these controls and procedures to the valuations received from Peoples’ third-party service provider. During the quarter and six months ended June 30, 2025, there were no transfers into Level 3. ​ The following methods and assumptions were used by the Company to calculate fair values and related carrying amounts of financial instruments: ​ Investment securities: The fair values of U.S. Treasury securities and marketable equity securities are based on quoted market prices from active exchange markets. The fair values of debt securities are based on pricing from a matrix pricing model. ​ Interest rate swaps and floors: The Company’s interest rate swaps and options are reported at fair value utilizing Level 2 inputs. Values of these instruments are obtained through an independent pricing source utilizing information which may include market observed quotations for interest rate, forward rates, rate volatility, and volatility surface. Derivative contracts create exposure to interest rate movements as well as risks from the potential of non-performance of the counterparty. ​ Individually evaluated loans: Fair values for individually evaluated loans are estimated using underlying collateral values, where applicable. ​ Other real estate owned: Other real estate owned ("OREO") represents properties that the Company has acquired through foreclosure by either accepting a deed in lieu of foreclosure, or by taking possession of assets that collateralized a loan, and former bank premises that are no longer used for operations or for future expansion. The Company reports OREO at the lower of cost or fair value less cost to sell, adjusted periodically based on a current appraisal. Write-downs and any gain or loss upon the sale of OREO is recorded in other noninterest income. OREO is reported in other assets on the consolidated balance sheets. OREO had a carrying amount of $711 thousand and $738 thousand at June 30, 2025 and December 31, 2024, respectively. During the year ended December 31, 2024, one residential real estate property with a carrying value of $27 thousand and one former community banking office with a carrying value of $711 thousand were transferred to OREO. Other real estate owned is classified within Level 3 in the fair value hierarchy based on appraisals, letters of intent or agreement of sale received from third parties. ​ ​ Assets and liabilities measured at fair value on a recurring basis at June 30, 2025 and December 31, 2024 are summarized as follows: ​
