Fair value estimates |
Fair value of estimates | 7. 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. ​ During the periods ended September 30, 2023 and December 31, 2022 there were no transfers in or out of 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 options: 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. ​ ​ Assets and liabilities measured at fair value on a recurring basis at September 30, 2023 and December 31, 2022 are summarized as follows: ​
