Fair Value | Note 2 — Fair Value Measurements ​ ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”), defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. ASC 820 defines fair value as 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; it also establishes a fair value hierarchy that prioritizes the inputs used in valuation methodologies into the following three levels: ​
| ● | Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities.
| ● | Level 2 Inputs - Observable inputs other than Level 1 inputs, 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 for substantially the full term of the assets or liabilities.
| ● | Level 3 Inputs - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
​ A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy is set forth below. ​ The following table represents assets and liabilities reported on the consolidated balance sheets at their fair value on a recurring basis as of September 30, 2019 by level within the fair value measurement hierarchy: ​

​ Available-for-sale debt securities are classified within Level 2 of the valuation hierarchy. Equity securities with readily determinable fair values are classified within Level 1. For debt investments classified as Level 2 in the fair value hierarchy, we obtain fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. ​ Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis. The instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). ​ The following table represents financial instruments measured at fair value on a non-recurring basis as of and for the period ended September 30, 2019 by level within the fair value measurement hierarchy: ​

​ Our assets measured at fair value on a non-recurring basis are limited to impaired loans, other real estate owned, and an equity investment without a readily determinable fair value. The determination of the fair value of the equity investment without a readily determinable fair value is based on the estimated value to be received upon the sale of the investment, which is expected to occur at the end of 2019. Impaired loans are classified within Level 3 of the valuation hierarchy. The fair value of impaired loans is derived in accordance with FASB ASC 310, “Receivables”. Impaired loans are primarily comprised of collateral-dependent commercial loans. As the primary sources of loan repayments decline, the secondary repayment source, the collateral, takes on greater significance. Correctly evaluating the fair value becomes even more important. Re-measurement of the impaired loan to fair value is done through a specific valuation allowance included in the allowance for probable loan losses. The fair value of impaired loans is based on the fair value of the collateral, as determined through either an appraisal or evaluation process. The basis for our appraisal and appraisal review process is based on regulatory guidelines and strives to comply with all regulatory appraisal laws, regulations, and the Uniform Standards of Professional Appraisal Practice. All appraisals and evaluations are “as is” (the property’s highest and best use) valuations based on the current conditions of the property/project at that point in time. The determination of the fair value of the collateral is based on the net realizable value, which is the appraised value less any closing costs, when applicable. As of September 30, 2019, we had $10,666,000 of impaired commercial collateral dependent loans, of which $7,184,000 had an appraisal performed within the immediately preceding twelve months, and of which $1,490,000 had an evaluation performed within the immediately preceding twelve months. As of December 31, 2018, we had approximately $14,306,000 of impaired commercial collateral dependent loans, of which $10,911,000 had an appraisal performed within the immediately preceding twelve months and of which $0 had an evaluation performed within the immediately preceding twelve months. ​ Our determination to either seek an appraisal or to perform an evaluation begins in weekly credit quality meetings, where the committee analyzes the existing collateral values of the impaired loans and where obsolete appraisals are identified. In order to determine whether we would obtain a new appraisal or perform an internal evaluation to determine the fair value of the collateral, the credit committee reviews the existing appraisal to determine if the collateral value is reasonable in view of the current use of the collateral and the economic environment related to the collateral. If the analysis of the existing appraisal does not find that the collateral value is reasonable under the current circumstances, we would obtain a new appraisal on the collateral or perform an internal evaluation of the collateral. The ultimate decision to get a new appraisal rests with the independent credit administration group. A new appraisal is not required if an internal evaluation, as performed by in-house experts, is able to appropriately update the original appraisal assumptions to reflect current market conditions and provide an estimate of the collateral’s market value for impairment analysis. The internal evaluations must be in writing and contain sufficient information detailing the analysis, assumptions and conclusions, and they must support performing an evaluation in lieu of ordering a new appraisal. ​ Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such property (as determined by independent appraisal) within Level 3 of the fair value hierarchy. Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the allowance for probable loan losses, if necessary. The fair value is reviewed periodically and subsequent write-downs are made, accordingly, through a charge to operations. Other real estate owned is included in other assets on the consolidated financial statements. For the three and nine months ended September 30, 2019 and the twelve months ended December 31, 2018, we recorded $33,000, $9,533,000, and $170,000, respectively, in charges to the allowance for probable loan losses in connection with loans transferred to other real estate owned. The $9,500,000 charge recorded in the second quarter of 2019 is related to the deterioration on one loan relationship discussed further in Note 4 – Allowance for Loan Losses. For the three and nine months ended September 30, 2019 and the twelve months ended December 31, 2018, we recorded $66,000, $154,000, and $3,071,000, respectively, in adjustments to fair value in connection with other real estate owned. ​ The fair value estimates, methods, and assumptions for our financial instruments at September 30, 2019 and December 31, 2018 are outlined below. ​ Cash and Cash Equivalents ​ For these short-term instruments, the carrying amount is a reasonable estimate of fair value. ​ Time Deposits with Banks ​ The carrying amounts of time deposits with banks approximate fair value. ​ Investment Securities Held-to-Maturity ​ The carrying amounts of investments held-to-maturity approximate fair value. ​ Investment Securities ​ For investment securities, which include U.S. Treasury securities, obligations of other U.S. government agencies, obligations of states and political subdivisions and mortgage pass-through and related securities, fair values are from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. See disclosures of fair value of investment securities in Note 6. ​ Loans ​ Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial, real estate and consumer loans, as outlined by regulatory reporting guidelines. Each category is segmented into fixed and variable interest rate terms and by performing and non-performing categories. ​ For variable rate performing loans, the carrying amount approximates the fair value. For fixed-rate performing loans, except residential mortgage loans, the fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. For performing residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed-rate performing loans are within Level 3 of the fair value hierarchy. At September 30, 2019 and December 31, 2018, the carrying amount of fixed-rate performing loans was $1,522,399,000 and $1,515,437,000, respectively, and the estimated fair value was $1,503,049,000 and $1,469,231,000, respectively. ​ Accrued Interest ​ The carrying amounts of accrued interest approximate fair value. ​ Deposits ​ The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings accounts and interest bearing demand deposit accounts, was equal to the amount payable on demand as of September 30, 2019 and December 31, 2018. The fair value of time deposits is based on the discounted value of contractual cashflows. The discount rate is based on currently offered rates. Time deposits are within Level 3 of the fair value hierarchy. At September 30, 2019 and December 31, 2018, the carrying amount of time deposits was $1,981,369,000 and $1,973,468,000, respectively, and the estimated fair value was $1,981,073,000 and $1,976,156,000, respectively. ​ Securities Sold Under Repurchase Agreements ​ Securities sold under repurchase agreements include short- and long-term maturities. Due to the contractual terms of the short-term instruments, the carrying amounts approximated fair value at September 30, 2019 and December 31, 2018. ​ Junior Subordinated Deferrable Interest Debentures ​ We currently have floating-rate junior subordinated deferrable interest debentures outstanding. Due to the contractual terms of the floating-rate junior subordinated deferrable interest debentures, the carrying amounts approximated fair value at September 30, 2019 and December 31, 2018. ​ Other Borrowed Funds ​ We currently have short- and long-term borrowings issued from the Federal Home Loan Bank (“FHLB”). Due to the contractual terms of the short-term borrowings, the carrying amounts approximated fair value at September 30, 2019 and December 31, 2018. The long-term borrowings outstanding at September 30, 2019 and December 31, 2018 are fixed-rate borrowings and the fair value is based on established market spreads for similar types of borrowings. The fixed rate long-term borrowings are included in Level 2 of the fair value hierarchy. At September 30, 2019 and December 31, 2018, the carrying amount of the fixed rate long-term FHLB borrowings was $436,556,000 and $436,690,000, respectively, and the estimated fair value was $463,409,000 and $436,238,000, respectively. ​ Commitments to Extend Credit and Letters of Credit ​ Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value. ​ Limitations ​ Fair value estimates are made at a point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time our entire holdings of a particular financial instrument. Because no market exists for a significant portion of our financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. ​ Fair value estimates are based on existing on- and off-statement of condition financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value estimates have not been considered in the above estimates.
