(the "Parent Company") and its wholly-owned subsidiary, Unity Bank (the "Bank" or when consolidated with the Parent Company, the "Company"), and reflect all adjustments and disclosures which are generally routine and recurring in nature, and in the opinion of management, necessary for a fair presentation of interim results. The Bank has multiple subsidiaries used to hold part of its investment and loan portfolios and OREO properties. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current year presentation, with no impact on current earnings or shareholders’ equity. The financial information has been prepared in accordance with U.S. generally accepted accounting principles and has not been audited. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses during the reporting periods. Actual results could differ from those estimates. Amounts requiring the use of significant estimates include the allowance for loan losses, valuation of deferred tax and servicing assets, the carrying value of loans held for sale and other real estate owned, the valuation of securities and the determination of other-than-temporary impairment for securities and fair value disclosures. Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in economic conditions. The markets served by the Company have been significantly impacted by the COVID-19 pandemic, which started during the first quarter of 2020. The Company continues to assess the financial impact of the COVID-19 pandemic. The interim unaudited Consolidated Financial Statements included herein have been prepared in accordance with instructions for Form 10-Q and the rules and regulations of the Securities and Exchange Commission (“SEC”) and consist of normal recurring adjustments necessary for the fair presentation of interim results. The results of operations for the nine months ended September 30, 2020 are not necessarily indicative of the results which may be expected for the entire year. As used in this Form 10-Q, “we” and “us” and “our” refer to Unity Bancorp, Inc., and its consolidated subsidiary, Unity Bank, depending on the context. Certain information and financial disclosures required by U.S. generally accepted accounting principles have been condensed or omitted from interim reporting pursuant to SEC rules. Interim financial statements should be read in conjunction with the Company’s Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Other-Than-Temporary Impairment The Company has a process in place to identify securities that could potentially incur credit impairment that is other-than-temporary. This process involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concern warrants such evaluation. This evaluation considers relevant facts and circumstances in evaluating whether a credit or interest rate-related impairment of a security is other-than-temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value has been below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for fixed maturity securities, the intent to sell a security or whether it is more likely than not the Company will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity and for equity securities, our ability and intent to hold the security for a forecasted period of time that allows for the recovery in value. Management assesses its intent to sell or whether it is more likely than not that it will be required to sell a security before recovery of its amortized cost basis less any current-period credit losses. For debt securities that are considered other-than-temporarily impaired with no intent to sell and no requirement to sell prior to recovery of its amortized cost basis, the amount of the impairment is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security’s fair value and the present value of future expected cash flows is due to factors that are not credit related and is recognized in other comprehensive income. For debt securities where management has the intent to sell, the amount of the impairment is reflected in earnings as realized losses. The present value of expected future cash flows is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The asset-backed securities cash flow estimates are based on bond specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate bond cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using bond specific facts and circumstances including timing, security interests and loss severity. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Loans Loans Held for Sale Loans held for sale represent the guaranteed portion of Small Business Administration (“SBA”) loans, other than loans originated under the Paycheck Protection Program, and are reflected at the lower of aggregate cost or market value. The Company originates loans to customers under an SBA program that historically has provided for SBA guarantees of up to 90 percent of each loan. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. The net amount of loan origination fees on loans sold is included in the carrying value and in the gain or loss on the sale. When sales of SBA loans do occur, the premium received on the sale and the present value of future cash flows of the servicing assets are recognized in income. All criteria for sale accounting must be met in order for the loan sales to occur; see details under the “Transfers of Financial Assets” heading above. Servicing assets represent the estimated fair value of retained servicing rights, net of servicing costs, at the time loans are sold. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on stratifying the underlying financial assets by date of origination and term. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment, if temporary, would be reported as a valuation allowance. Serviced loans sold to others are not included in the accompanying Consolidated Balance Sheets. Income and fees collected for loan servicing are credited to noninterest income when earned, net of amortization on the related servicing assets. Loans Held to Maturity Loans held to maturity are stated at the unpaid principal balance, net of unearned discounts and deferred loan origination fees and costs. In accordance with the level yield method, loan origination fees, net of direct loan origination costs, are deferred and recognized over the estimated life of the related loans as an adjustment to the loan yield. Interest is credited to operations primarily based upon the principal balance outstanding. Loans are reported as past due when either interest or principal is unpaid in the following circumstances: fixed payment loans when the borrower is in arrears for two or more monthly payments; open end credit for two or more billing cycles; and single payment notes if interest or principal remains unpaid for 30 days or more. Nonperforming loans consist of loans that are not accruing interest as a result of principal or interest being in default for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt (nonaccrual loans). When a loan is classified as nonaccrual, interest accruals are discontinued and all past due interest previously recognized as income is reversed and charged against current period earnings. Generally, until the loan becomes current, any payments received from the borrower are applied to outstanding principal until such time as management determines that the financial condition of the borrower and other factors merit recognition of a portion of such payments as interest income. Loans may be returned to an accrual status when the ability to collect is reasonably assured and when the loan is brought current as to principal and interest. Loans are charged off when collection is sufficiently questionable and when the Company can no longer justify maintaining the loan as an asset on the balance sheet. Loans qualify for charge-off when, after thorough analysis, all possible sources of repayment are insufficient. These include: 1) potential future cash flows, 2) value of collateral, and/or 3) strength of co-makers and guarantors. All unsecured loans are charged off upon the establishment of the loan’s nonaccrual status. Additionally, all loans classified as a loss or that portion of the loan classified as a loss is charged off. All loan charge-offs are approved by the Board of Directors. Troubled debt restructurings ("TDRs") occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider. These concessions typically include reductions in interest rate, extending the maturity of a loan, or a combination of both. Interest income on accruing TDRs is credited to operations primarily based upon the principal amount outstanding, as stated in the paragraphs above. The Company evaluates its loans for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The Company has defined impaired loans to be all TDRs and nonperforming loans individually evaluated for impairment. Impairment is evaluated in total for smaller-balance loans of a similar nature (consumer and residential mortgage loans), and on an individual basis for all other loans. Impairment of a loan is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, or as a practical expedient, based on a loan’s observable market price or the fair value of collateral, net of estimated costs to sell, if the loan is collateral-dependent. If the value of the impaired loan is less than the recorded investment in the loan, the Company establishes a valuation allowance, or adjusts existing valuation allowances, with a corresponding charge to the provision for loan losses. For additional information on loans, see Note 8 to the Consolidated Financial Statements and the section titled "Loan Portfolio" under Item 2. Management’s Discussion and Analysis. Allowance for Loan Losses and Reserve for Unfunded Loan Commitments The allowance for loan losses is maintained at a level management considers adequate to provide for probable loan losses as of the balance sheet date. The allowance is increased by provisions charged to expense and is reduced by net charge-offs. The level of the allowance is based on management’s evaluation of probable losses in the loan portfolio, after consideration of prevailing economic conditions in the Company’s market area, the volume and composition of the loan portfolio, and historical loan loss experience. The allowance for loan losses consists of specific reserves for individually impaired credits and TDRs, reserves for nonimpaired loans based on historical loss factors and reserves based on general economic factors and other qualitative risk factors such as changes in delinquency trends, industry concentrations or local/national economic trends. This risk assessment process is performed at least quarterly, and, as adjustments become necessary, they are realized in the periods in which they become known. Although management attempts to maintain the allowance at a level deemed adequate to provide for probable losses, future additions to the allowance may be necessary based upon certain factors including changes in market conditions and underlying collateral values. In addition, various regulatory agencies periodically review the adequacy of the Company’s allowance for loan losses. These agencies may require the Company to make additional provisions based on their judgments about information available to them at the time of their examination. The Company maintains an allowance for unfunded loan commitments that is maintained at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the allowance are made through other expenses and applied to the allowance which is maintained in other liabilities. For additional information on the allowance for loan losses and unfunded loan commitments, see Note 9 to the Consolidated Financial Statements and the sections titled "Asset Quality" and "Allowance for Loan Losses and Reserve for Unfunded Loan Commitments" under Item 2. Management’s Discussion and Analysis. Income Taxes The Company accounts for income taxes according to the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates applicable to taxable income for the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation reserves are established against certain deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. Increases or decreases in the valuation reserve are charged or credited to the income tax provision. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that ultimately would be sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. The evaluation of a tax position taken is considered by itself and not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest and penalties associated with unrecognized tax benefits would be recognized in income tax expense on the income statement.

Earnings Per Share [Abstract]
Net Income per Share	NOTE 3. Net Income per Share Basic net income per common share is calculated as net income divided by the weighted average common shares outstanding during the reporting period. Diluted net income per common share is computed similarly to that of basic net income per common share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares, principally stock options, were issued during the reporting period utilizing the Treasury stock method. The following is a reconciliation of the calculation of basic and diluted income per share: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ (In thousands, except per share amounts) 2020 2019 2020 2019 ​ Net income ​ $ 5,760 ​ $ 5,959 ​ $ 16,299 ​ $ 17,533 ​ Weighted average common shares outstanding - Basic ​ 10,630 ​ 10,863 ​ 10,768 ​ 10,836 ​ Plus: Potential dilutive common stock equivalents ​ 76 ​ 173 ​ 107 ​ 183 ​ Weighted average common shares outstanding - Diluted ​ 10,706 ​ 11,036 ​ 10,875 ​ 11,019 ​ Net income per common share - Basic ​ $ 0.54 ​ $ 0.55 ​ $ 1.51 ​ $ 1.62 ​ Net income per common share - Diluted ​ 0.54 ​ 0.54 ​ 1.50 ​ 1.59 ​ Stock options and common stock excluded from the income per share calculation as their effect would have been anti-dilutive ​ 430 ​ 251 ​ 413 ​ 237 ​ ​

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 4. Income Taxes The Company follows FASB ASC Topic 740, “Income Taxes,” On July 1, 2018, New Jersey’s Assembly Bill 4202 was signed into law. The bill, effective January 1, 2018, imposes a temporary surtax on corporations earning New Jersey allocated taxable income in excess of $1 million at a rate of 2.5 percent for tax years beginning on or after January 1, 2018, through December 31, 2019, and at 1.5 percent for tax years beginning on or after January 1, 2020, through December 31, 2021. In addition, New Jersey adopted mandatory unitary combined reporting for its Corporation Business Tax, which became effective for periods on or after January 1, 2019. On September 29, 2020, New Jersey’s Assembly Bill 4721 was signed into law. The bill, retroactively effective January 1, 2020, extends the 2.5% corporate income surtax until December 31, 2023. The Division of Taxation will waive any underpayment penalties on 2020 estimated tax payments related to the retroactive increase. In addition, if the federal corporate tax rate is increased to a rate of at least 35% of taxable income, the surtax will be suspended. For the quarter ended September 30, 2020, the Company reported income tax expense of $1.9 million for an effective tax rate of 24.5 percent, compared to an income tax expense of $1.7 million and an effective tax rate of 22.0 percent for the prior year’s quarter. For the nine months ended September 30, 2020, the Company reported income tax expense of $5.0 million for an effective tax rate of 23.3 percent, compared to an income tax expense of $4.8 million and an effective tax rate of 21.6 percent for the nine months ended September 30, 2019. The Company did not recognize or accrue any interest or penalties related to income taxes during the three or the nine months ended September 30, 2020 or 2019. The Company did not have an accrual for uncertain tax positions as of September 30, 2020 or December 31, 2019, as deductions taken and benefits accrued are based on widely understood administrative practices and procedures and are based on clear and unambiguous tax law. Tax returns for all years 2015 and thereafter are subject to future examination by tax authorities.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 6. Fair Value Fair Value Measurement The Company follows FASB ASC Topic 820, “Fair Value Measurement and Disclosures,” Level 1 Inputs ● Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. ● Generally, this includes debt and equity securities and derivative contracts that are traded in an active exchange market (i.e. New York Stock Exchange), as well as certain U.S. Treasury, U.S. Government and sponsored entity agency mortgage-backed securities that are highly liquid and are actively traded in over-the-counter markets. ​ Level 2 Inputs ● Quoted prices for similar assets or liabilities in active markets. ● Quoted prices for identical or similar assets or liabilities in inactive markets. ● Inputs other than quoted prices that are observable, either directly or indirectly, for the term of the asset or liability (i.e., interest rates, yield curves, credit risks, prepayment speeds or volatilities) or “market corroborated inputs.” ● Generally, this includes U.S. Government and sponsored entity mortgage-backed securities, corporate debt securities and derivative contracts ​ Level 3 Inputs ● Prices or valuation techniques that require inputs that are both unobservable (i.e. supported by little or no market activity) and that are significant to the fair value of the assets or liabilities. ● These assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. ​ Fair Value on a Recurring Basis The following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis: Debt Securities Available for Sale The fair value of available for sale ("AFS") debt securities is the market value based on quoted market prices, when available, or market prices provided by recognized broker dealers (Level 1). If listed prices or quotes are not available, fair value is based upon quoted market prices for similar or identical assets or other observable inputs (Level 2) or externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). As of September 30, 2020, the fair value of the Company’s AFS debt securities portfolio was $48.7 million. Approximately 40 percent of the portfolio was made up of residential mortgage-backed securities, which had a fair value of $19.7 million at September 30, 2020. Approximately $19.4 million of the residential mortgage-backed securities are guaranteed by the Government National Mortgage Association ("GNMA"), the Federal National Mortgage Association ("FNMA") or the Federal Home Loan Mortgage Corporation ("FHLMC"). The underlying loans for these securities are residential mortgages that are geographically dispersed throughout the United States. Most of the Company’s AFS debt securities were classified as Level 2 assets at September 30, 2020. The valuation of AFS debt securities using Level 2 inputs was primarily determined using the market approach, which uses quoted prices for similar assets or liabilities in active markets and all other relevant information. It includes model pricing, defined as valuing securities based upon their relationship with other benchmark securities. Included in the Company’s AFS debt securities are three corporate bonds which are classified as Level 3 assets at September 30, 2020, which were previously classified as Level 2 assets. The valuation of these corporate bonds is determined using broker quotes, third-party vendor prices, or other valuation techniques, such as discounted cash flow techniques. Market inputs used in the other valuation techniques or underlying third-party vendor prices or broker quotes include benchmark and government bond yield curves, credit spreads, and trade execution data. The following table presents a reconciliation of the Level 3 available for sale debt securities measured at fair value on a recurring basis for the three and nine months ended September 30, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, (In thousands) 2020 2019 ​ 2020 2019 Balance at beginning of period (1) $ 6,243 $ — ​ $ 6,238 $ — Purchases/additions ​ ​ — ​ ​ — ​ ​ — ​ ​ — Sales/reductions ​ — ​ — ​ — ​ — Realized gains (losses) ​ — ​ — ​ — ​ — Unrealized losses ​ (728) ​ — ​ (723) ​ — Balance at end of period ​ $ 5,515 ​ $ — ​ $ 5,515 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) Includes AFS debt securities classified as Level 2 at December 31, 2019, which were transferred to Level 3 during the period ended September 30, 2020. ​ Equity Securities with Readily Determinable Fair Values The fair value of equity securities is the market value based on quoted market prices, when available, or market prices provided by recognized broker dealers (Level 1). If listed prices or quotes are not available, fair value is based upon quoted market prices for similar or identical assets or other observable inputs (Level 2) or externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). As of September 30, 2020, the fair value of the Company’s equity securities portfolio was $1.7 million. All of the Company’s equity securities were classified as Level 2 assets at September 30, 2020. The valuation of equity securities using Level 2 inputs was primarily determined using the market approach, which uses quoted prices for similar assets or liabilities in active markets and all other relevant information. There were no changes in the inputs or methodologies used to determine fair value during the period ended September 30, 2020, as compared to the periods ended December 31, 2019 and September 30, 2019. Loans Held for Sale Fair Value for loans held for sale is derived from quoted market prices for similar loans, in which case they are characterized as Level 2 assets in the fair value hierarchy. Interest Rate Swap Agreements The fair value of interest rate swap agreements is the market value based on quoted market prices, when available, or market prices provided by recognized broker dealers (Level 1). If listed prices or quotes are not available, fair value is based upon quoted market prices for similar or identical assets or other observable inputs (Level 2) or externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). The Company’s derivative instruments are classified as Level 2 assets, as the readily observable market inputs to these models are validated to external sources, such as industry pricing services, or are corroborated through recent trades, dealer quotes, yield curves, implied volatility or other market-related data.

The following is a description of the valuation methodologies used for instruments measured at fair value on a nonrecurring basis: Appraisal Policy All appraisals must be performed in accordance with the Uniform Standards of Professional Appraisal Practice ("USPAP"). Appraisals are certified to the Company and performed by appraisers on the Company’s approved list of appraisers. Evaluations are completed by a person independent of Company management. The content of the appraisal depends on the complexity of the property. Appraisals are completed on a “retail value” and an “as is value.” OREO The fair value of OREO is determined using third party appraisals, which may be discounted based on management’s review and changes in market conditions (Level 3 Inputs). Impaired Collateral-Dependent Loans The fair value of impaired collateral-dependent loans is derived in accordance with FASB ASC Topic 310, “Receivables.” The valuation allowance for impaired loans is included in the allowance for loan losses in the consolidated balance sheets. At September 30, 2020, the valuation allowance for impaired loans was $978 thousand, an increase of $564 thousand from $414 thousand at December 31, 2019. Fair Value of Financial Instruments FASB ASC Topic 825, “Financial Instruments,” Cash and Cash Equivalents For these short-term instruments, the carrying value is a reasonable estimate of fair value. Securities The fair value of securities is based upon quoted market prices for similar or identical assets or other observable inputs (Level 2) or externally developed models that use unobservable inputs due to limited or no market activity of the instrument (Level 3). SBA Loans Held for Sale The fair value of SBA loans held for sale is estimated by using a market approach that includes significant other observable inputs. Loans The fair value of loans is estimated by discounting the future cash flows using current market rates that reflect the interest rate risk inherent in the loan, except for previously discussed impaired loans. FHLB Stock Federal Home Loan Bank stock is carried at cost. Carrying value approximates fair value based on the redemption provisions of the issues. Servicing Assets Servicing assets do not trade in an active, open market with readily observable prices. The Company estimates the fair value of servicing assets using discounted cash flow models incorporating numerous assumptions from the perspective of a market participant including market discount rates and prepayment speeds. Accrued Interest The carrying amounts of accrued interest approximate fair value. Deposit Liabilities The fair value of demand deposits and savings accounts is the amount payable on demand at the reporting date (i.e. carrying value). The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using current market rates. Borrowed Funds and Subordinated Debentures The fair value of borrowings is estimated by discounting the projected future cash flows using current market rates. Standby Letters of Credit At September 30, 2020, the Bank had standby letters of credit outstanding of $4.5 million, compared to $4.8 million at December 31, 2019. The fair value of these commitments is nominal. The table below presents the carrying amount and estimated fair values of the Company’s financial instruments presented as of September 30, 2020 and December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2020 ​ December 31, 2019 ​ ​ Fair value ​ Carrying ​ Estimated ​ Carrying ​ Estimated (In thousands) level amount fair value amount fair value Financial assets: ​ ​ ​ ​ Cash and cash equivalents Level 1 ​ $ 201,395 ​ $ 201,395 ​ $ 158,016 ​ $ 158,016 Securities (1) Level 2 ​ 50,387 ​ 50,387 ​ 66,564 ​ 66,564 SBA loans held for sale Level 2 ​ 6,192 ​ 7,175 ​ 13,529 ​ 14,862 Loans, net of allowance for loan losses (2) Level 2 ​ 1,584,862 ​ 1,604,944 ​ 1,395,634 ​ 1,398,997 FHLB stock Level 2 ​ 12,394 ​ 12,394 ​ 14,184 ​ 14,184 Servicing assets Level 3 ​ 2,138 ​ 2,138 ​ 2,026 ​ 2,026 Accrued interest receivable Level 2 ​ 10,169 ​ 10,169 ​ 6,984 ​ 6,984 OREO Level 3 ​ 711 ​ ​ 711 ​ ​ 1,723 ​ 1,723 Financial liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits Level 2 ​ 1,493,440 ​ 1,498,622 ​ 1,250,114 ​ 1,252,082 Borrowed funds and subordinated debentures Level 2 ​ 250,310 ​ 252,596 ​ 293,310 ​ 292,766 Accrued interest payable Level 2 ​ 283 ​ 283 ​ 455 ​ 455 ​ (1) Includes corporate securities that are considered Level 3 and reported separately in the table under the “Fair Value on a Recurring Basis” heading. These securities had book values of $6.2 million and market values of $5.5 million. (2) Includes collateral-dependent impaired loans that are considered Level 3 and reported separately in the tables under the “Fair Value on a Nonrecurring Basis” heading. Collateral-dependent impaired loans, net of specific reserves totaled $7.9 million and $1.9 million at September 30, 2020 and December 31, 2019, respectively. 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 the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s 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. In addition, the tax ramifications related to the effect of fair value estimates have not been considered in the above estimates.

Loans	NOTE 8. Loans The following table sets forth the classification of loans by class, including unearned fees, deferred costs and excluding the allowance for loan losses as of September 30, 2020 and December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) September 30, 2020 December 31, 2019 SBA loans held for investment ​ $ 47,125 ​ $ 35,767 SBA PPP loans ​ ​ 138,895 ​ ​ — Commercial loans ​ ​ SBA 504 loans ​ 21,811 ​ 26,726 Commercial other ​ 115,715 ​ 112,014 Commercial real estate ​ 596,243 ​ 578,643 Commercial real estate construction ​ 65,804 ​ 47,649 Residential mortgage loans ​ 473,420 ​ 467,706 Consumer loans ​ ​ ​ ​ Home equity ​ 67,257 ​ 69,589 Consumer other ​ 80,829 ​ 73,935 Total loans held for investment ​ $ 1,607,099 ​ $ 1,412,029 SBA loans held for sale ​ 6,192 ​ 13,529 Total loans ​ $ 1,613,291 ​ $ 1,425,558 ​ Loans are made to individuals as well as commercial entities. Specific loan terms vary as to interest rate, repayment, and collateral requirements based on the type of loan requested and the credit worthiness of the prospective borrower. Credit risk tends to be geographically concentrated in that a majority of the loan customers are located in the markets serviced by the Bank. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. A description of the Company’s different loan segments follows: SBA Loans: On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law. It contains substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic. The CARES Act includes a range of other provisions designed to support the U.S. economy and mitigate the impact of COVID-19 on financial institutions and their customers, including through the authorization of various relief programs and measures that the U.S. Department of the Treasury, the Small Business Administration, the Federal Reserve Board (“FRB”) and other federal banking agencies have implemented or may implement. The CARES Act provides assistance to small businesses through the establishment of the SBA Paycheck Protection Program ("PPP"). The PPP generally provides small businesses with funds to pay up to 24 weeks of payroll costs, including certain benefits. The funds are provided in the form of loans that may be fully or partially forgiven when used for payroll costs, interest on mortgages, rent, and utilities. The payments on these loans will be deferred for up to six months. Loans made after June 5, 2020, mature in five years, and loans made prior to June 5, 2020, mature in two years but can be extended to five years if the lender agrees. Forgiveness of the PPP loans is based on the borrower maintaining or quickly rehiring employees and maintaining salary levels. Most small businesses with 500 or fewer employees are eligible. Applications for the PPP loans started on April 3, 2020 and was extended through August 8, 2020. As an existing SBA 7(a) lender, the Company opted to participate in the program. Commercial Loans: Residential Mortgage and Consumer Loans: Inherent in the lending function is credit risk, which is the possibility a borrower may not perform in accordance with the contractual terms of their loan. A borrower’s inability to pay their obligations according to the contractual terms can create the risk of past due loans and, ultimately, credit losses, especially on collateral deficient loans. The Company minimizes its credit risk by loan diversification and adhering to credit administration policies and procedures. Due diligence on loans begins when we initiate contact regarding a loan with a borrower. Documentation, including a borrower’s credit history, materials establishing the value and liquidity of potential collateral, the purpose of the loan, the source of funds for repayment of the loan, and other factors, are analyzed before a loan is submitted for approval. The loan portfolio is then subject to on-going internal reviews for credit quality which in part is derived from ongoing collection and review of borrowers’ financial information, as well as independent credit reviews by an outside firm. The Company’s extension of credit is governed by the Credit Risk Policy which was established to control the quality of the Company’s loans. This policy and the underlying procedures are reviewed and approved by the Board of Directors on a regular basis. Credit Ratings For SBA 7(a), SBA 504 and commercial loans, management uses internally assigned risk ratings as the best indicator of credit quality. A loan’s internal risk rating is updated at least annually and more frequently if circumstances warrant a change in risk rating. The Company uses a 1 through 10 loan grading system that follows regulatory accepted definitions. Pass: Special Mention: Substandard: A risk rating of 9 is used for borrowers that have all the weaknesses inherent in a loan with a risk rating of 8, with the added characteristic that the weaknesses make collection of debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely. The possibility of loss is extremely high, but because of certain important, reasonably specific pending factors that may work to strengthen the assets, the loans’ classification as estimated losses is deferred until a more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures; capital injection; perfecting liens on additional collateral; and refinancing plans. Partial charge-offs are likely. Loss: For residential mortgage and consumer loans, management uses performing versus nonperforming as the best indicator of credit quality. Nonperforming loans consist of loans that are not accruing interest (nonaccrual loans) as a result of principal or interest being in default for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt. These credit quality indicators are updated on an ongoing basis, as a loan is placed on nonaccrual status as soon as management believes there is sufficient doubt as to the ultimate ability to collect interest on a loan. At September 30, 2020, the Company owned $648 thousand in residential consumer properties that were included in OREO in the Consolidated Balance Sheets, compared to $1.7 million at December 31, 2019. Additionally, there were $4.8 million of residential consumer loans in the process of foreclosure at September 30, 2020, compared to $3.6 million at December 31, 2019.

Loans past due 90 days or more and still accruing interest are not included in nonperforming loans and generally represent loans that are well collateralized and in the process of collection. The risk of loss is difficult to quantify and is subject to fluctuations in collateral values, general economic conditions and other factors. The Company values its collateral through the use of appraisals, broker price opinions, and knowledge of its local market.

Impaired Loans The Company has defined impaired loans to be all nonperforming loans individually evaluated for impairment and TDRs. Management considers a loan impaired when, based on current information and events, it is determined that the Company will not be able to collect all amounts due according to the loan contract. Impairment is evaluated on an individual basis for SBA and commercial loans. The following table provides detail on the Company’s impaired loans that are individually evaluated for impairment with the associated allowance amount, if applicable, as of September 30, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2020 ​ Unpaid ​ ​ ​ ​ ​ ​ principal ​ Recorded ​ Specific (In thousands) ​ balance ​ investment ​ reserves With no related allowance: ​ ​ ​ ​ SBA loans held for investment (1) ​ $ 2,367 ​ $ 2,267 ​ $ — Commercial loans ​ ​ ​ Commercial real estate ​ 673 ​ 673 ​ — Total commercial loans ​ 673 ​ 673 ​ — Residential mortgage loans ​ ​ 2,873 ​ ​ 2,768 ​ ​ — Consumer loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 1,293 ​ ​ 1,293 ​ ​ — Total impaired loans with no related allowance ​ 7,206 ​ 7,001 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ With an allowance: ​ ​ ​ SBA loans held for investment (1) ​ 392 ​ 367 ​ 233 Commercial loans ​ ​ ​ Commercial other ​ 148 ​ 130 ​ 130 Commercial real estate ​ 897 ​ 397 ​ 397 Total commercial loans ​ 1,045 ​ 527 ​ 527 Residential mortgage loans ​ ​ 954 ​ ​ 954 ​ ​ 218 Consumer loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Total impaired loans with a related allowance ​ 2,391 ​ 1,848 ​ 978 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total individually evaluated impaired loans: ​ ​ ​ SBA loans held for investment (1) ​ 2,759 ​ 2,634 ​ 233 Commercial loans ​ ​ ​ Commercial other ​ 148 ​ 130 ​ 130 Commercial real estate ​ 1,570 ​ 1,070 ​ 397 Total commercial loans ​ 1,718 ​ 1,200 ​ 527 Residential mortgage loans ​ ​ 3,827 ​ ​ 3,722 ​ ​ 218 Consumer loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 1,293 ​ ​ 1,293 ​ ​ — Total individually evaluated impaired loans ​ $ 9,597 ​ $ 8,849 ​ $ 978 ​ (1) Balances are reduced by amount guaranteed by the SBA of $812 thousand at September 30, 2020.

Impaired loans increased $6.5 million at September 30, 2020 compared to December 31, 2019. The increase in impaired loans was primarily due to residential mortgage and consumer loans. The following table presents the average recorded investments in impaired loans and the related amount of interest recognized during the time period in which the loans were impaired for the three and nine months ended September 30, 2020 and 2019. The average balances are calculated based on the month-end balances of impaired loans. When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method, and therefore no interest income is recognized. The interest income recognized on impaired loans noted below represents primarily accruing TDRs and nominal amounts of income recognized on a cash basis for well-collateralized impaired loans. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ ​ ​ 2020 ​ 2019 ​ ​ ​ ​ Interest ​ ​ Interest ​ ​ ​ ​ ​ ​ income ​ ​ ​ ​ income ​ ​ ​ Average ​ recognized ​ Average ​ recognized ​ ​ ​ recorded ​ on impaired ​ recorded ​ on impaired ​ (In thousands) ​ investment ​ loans ​ investment ​ loans ​ SBA loans held for investment (1) ​ $ 1,928 ​ $ 24 ​ $ 255 ​ $ 4 ​ Commercial loans ​ ​ ​ ​ ​ ​ Commercial other ​ 50 ​ — ​ 700 ​ 3 ​ Commercial real estate ​ 1,081 ​ 26 ​ 831 ​ 9 ​ Commercial real estate construction ​ ​ — ​ ​ 33 ​ ​ — ​ ​ — ​ Residential mortgage loans ​ ​ 4,850 ​ ​ 63 ​ ​ — ​ ​ — ​ Consumer loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 760 ​ ​ 29 ​ ​ — ​ ​ — ​ Consumer other ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Total ​ $ 8,669 ​ $ 175 ​ $ 1,786 ​ $ 16 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, ​ ​ 2020 ​ 2019 ​ ​ ​ Interest ​ ​ Interest ​ ​ ​ ​ ​ income ​ ​ ​ ​ income ​ ​ Average ​ recognized ​ Average ​ recognized ​ ​ recorded ​ on impaired ​ recorded ​ on impaired (In thousands) ​ investment ​ loans ​ investment ​ loans SBA loans held for investment (1) ​ $ 1,440 ​ $ 30 ​ $ 685 ​ $ 13 Commercial loans ​ ​ ​ ​ SBA 504 loans ​ 200 ​ 32 ​ — ​ — Commercial other ​ 51 ​ 25 ​ 236 ​ 3 Commercial real estate ​ 1,137 ​ 67 ​ 1,369 ​ 17 Commercial real estate construction ​ ​ — ​ ​ 33 ​ ​ — ​ ​ — Residential mortgage loans ​ ​ 5,533 ​ ​ 129 ​ ​ — ​ ​ — Consumer loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 536 ​ ​ 53 ​ ​ — ​ ​ — Consumer other ​ ​ 25 ​ ​ — ​ ​ — ​ ​ — Total ​ $ 8,922 ​ $ 369 ​ $ 2,290 ​ $ 33 ​ (1) Balances are reduced by the average amount guaranteed by the SBA of $687 thousand and $146 thousand for the nine months ended September 30, 2020 and 2019, respectively. TDRs The Company’s loan portfolio also includes certain loans that have been modified as TDRs. TDRs occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider, unless it results in a delay in payment that is insignificant. These concessions typically include reductions in interest rate, extending the maturity of a loan, or a combination of both. Under the CARES Act and regulatory guidance issued in regards to the COVID-19 pandemic, loan payment deferrals for periods of up to 180 days granted to borrowers adversely effected by the pandemic are not considered TDR’s if the borrower was current on its loan payments at year end 2019 or until the deferral was granted. When the Company modifies a loan, management evaluates for any possible impairment using either the discounted cash flows method, where the value of the modified loan is based on the present value of expected cash flows, discounted at the contractual interest rate of the original loan agreement, or by using the fair value of the collateral less selling costs if the loan is collateral-dependent. If management determines that the value of the modified loan is less than the recorded investment in the loan, impairment is recognized by segment or class of loan, as applicable, through an allowance estimate or charge-off to the allowance. This process is used, regardless of loan type, and for loans modified as TDRs that subsequently default on their modified terms. The Company had one performing TDR with a balance of $673 thousand and $705 thousand as of September 30, 2020 and December 31, 2019, respectively, which was included in the impaired loan numbers as of such dates. There were no specific reserves on the performing TDR as of September 30, 2020 compared to $57 thousand at December 31, 2019. The loan remains in accrual status since it continues to perform in accordance with the restructured terms. To date, the Company’s TDRs consisted of interest rate reductions, interest only periods, principal balance reductions, and maturity extensions. There were no loans modified during the three and nine months ended September 30, 2020 and 2019 that were deemed to be TDRs. There were no loans modified as a TDR within the previous 12 months that subsequently defaulted at some point during the three months ended September 30, 2020. In this case, the subsequent default is defined as 90 days past due or transferred to nonaccrual status.

Financing Receivable, Allowance for Credit Loss, Additional Information [Abstract]
Allowance for Loan Losses and Reserve for Unfunded Loan Commitments	NOTE 9. Allowance for Loan Losses and Reserve for Unfunded Loan Commitments Allowance for Loan Losses The Company has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in the loan portfolio. At a minimum, the adequacy of the allowance for loan losses is reviewed by management on a quarterly basis. For purposes of determining the allowance for loan losses, the Company has segmented the loans in its portfolio by loan type. Loans are segmented into the following pools: SBA 7(a), commercial, residential mortgages, and consumer loans. Certain portfolio segments are further broken down into classes based on the associated risks within those segments and the type of collateral underlying each loan. Commercial loans are divided into the following five classes: commercial real estate, commercial real estate construction, unsecured business line of credit, commercial other, and SBA 504. Consumer loans are divided into two classes as follows: home equity and other. The standardized methodology used to assess the adequacy of the allowance includes the allocation of specific and general reserves. The same standard methodology is used, regardless of loan type. Specific reserves are made to individual impaired loans and TDRs (see Note 1 for additional information on this term). The general reserve is set based upon a representative average historical net charge-off rate adjusted for the following environmental factors: delinquency and impairment trends, charge-off and recovery trends, volume and loan term trends, changes in risk and underwriting policy trends, staffing and experience changes, national and local economic trends, industry conditions and credit concentration changes. Within the five-year historical net charge-off rate, the Company weights the past three years more heavily as it believes it is more indicative of future charge-offs. All of the environmental factors are ranked and assigned a basis points value based on the following scale: low, low moderate, moderate, high moderate and high risk. Each environmental factor is evaluated separately for each class of loans and risk weighted based on its individual characteristics. ● For SBA 7(a) and commercial loans, the estimate of loss based on pools of loans with similar characteristics is made through the use of a standardized loan grading system that is applied on an individual loan level and updated on a continuous basis. The loan grading system incorporates reviews of the financial performance of the borrower, including cash flow, debt-service coverage ratio, earnings power, debt level and equity position, in conjunction with an assessment of the borrower’s industry and future prospects. It also incorporates analysis of the type of collateral and the relative loan to value ratio. ● For residential mortgage and consumer loans, the estimate of loss is based on pools of loans with similar characteristics. Factors such as credit score, delinquency status and type of collateral are evaluated. Factors are updated frequently to capture the recent behavioral characteristics of the subject portfolios, as well as any changes in loss mitigation or credit origination strategies, and adjustments to the reserve factors are made as needed. According to the Company’s policy, a loss (“charge-off”) is to be recognized and charged to the allowance for loan losses as soon as a loan is recognized as uncollectable. All credits which are 90 days past due must be analyzed for the Company’s ability to collect on the credit. Once a loss is known to exist, the charge-off approval process is immediately expedited. This charge-off policy is followed for all loan types. The allocated allowance is the total of identified specific and general reserves by loan category. The allocation is not necessarily indicative of the categories in which future losses may occur. The total allowance is available to absorb losses from any segment of the portfolio. The following tables detail the activity in the allowance for loan losses by portfolio segment for the three and nine months ended September 30, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, 2020 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Balance, beginning of period ​ $ 1,004 ​ $ 12,336 ​ $ 5,439 ​ $ 1,455 ​ $ 20,234 Charge-offs ​ (1) ​ — ​ — ​ — ​ (1) Recoveries ​ 3 ​ 1 ​ — ​ — ​ 4 Net recoveries ​ 2 ​ 1 ​ — ​ — ​ 3 Provision for loan losses charged to expense ​ 388 ​ 963 ​ 485 ​ 164 ​ 2,000 Balance, end of period ​ $ 1,394 ​ $ 13,300 ​ $ 5,924 ​ $ 1,619 ​ $ 22,237 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, 2019 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Balance, beginning of period ​ $ 1,321 ​ $ 9,144 ​ $ 4,198 ​ $ 1,302 ​ $ 15,965 Charge-offs ​ (99) ​ (500) ​ (130) ​ — ​ (729) Recoveries ​ 13 ​ 3 ​ — ​ — ​ 16 Net charge-offs ​ (86) ​ (497) ​ (130) ​ — ​ (713) Provision for (credit to) loan losses charged to expense ​ (68) ​ 778 ​ 52 ​ (12) ​ 750 Balance, end of period ​ $ 1,167 ​ $ 9,425 ​ $ 4,120 ​ $ 1,290 ​ $ 16,002 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, 2020 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Balance, beginning of period ​ $ 1,079 ​ $ 9,722 ​ $ 4,254 ​ $ 1,340 ​ $ 16,395 Charge-offs ​ (27) ​ (518) ​ (200) ​ — ​ (745) Recoveries ​ 83 ​ 504 ​ — ​ — ​ 587 Net recoveries (charge-offs) ​ 56 ​ (14) ​ (200) ​ — ​ (158) Provision for loan losses charged to expense ​ 259 ​ 3,592 ​ 1,870 ​ 279 ​ 6,000 Balance, end of period ​ $ 1,394 ​ $ 13,300 ​ $ 5,924 ​ $ 1,619 ​ $ 22,237 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, 2019 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Balance, beginning of period ​ $ 1,655 ​ $ 8,705 ​ $ 3,900 ​ $ 1,228 ​ $ 15,488 Charge-offs ​ (492) ​ (501) ​ (130) ​ (1) ​ (1,124) Recoveries ​ 16 ​ 12 ​ — ​ 10 ​ 38 Net (charge-offs) recoveries ​ (476) ​ (489) ​ (130) ​ 9 ​ (1,086) Provision for (credit to) loan losses charged to expense ​ (12) ​ 1,209 ​ 350 ​ 53 ​ 1,600 Balance, end of period ​ $ 1,167 ​ $ 9,425 ​ $ 4,120 ​ $ 1,290 ​ $ 16,002 ​ The following tables present loans and their related allowance for loan losses, by portfolio segment, as of September 30, 2020 and December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2020 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Allowance for loan losses ending balance: ​ ​ ​ ​ ​ Individually evaluated for impairment ​ $ 233 ​ $ 527 ​ $ 218 ​ $ — ​ $ 978 Collectively evaluated for impairment ​ 1,161 ​ 12,773 ​ 5,706 ​ 1,619 ​ 21,259 Total ​ $ 1,394 ​ $ 13,300 ​ $ 5,924 ​ $ 1,619 ​ $ 22,237 Loan ending balances: ​ ​ ​ ​ ​ Individually evaluated for impairment ​ $ 2,634 ​ $ 1,200 ​ $ 3,722 ​ $ 1,293 ​ $ 8,849 Collectively evaluated for impairment ​ 183,386 ​ 798,373 ​ 469,698 ​ 146,793 ​ 1,598,250 Total ​ $ 186,020 ​ $ 799,573 ​ $ 473,420 ​ $ 148,086 ​ $ 1,607,099 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2019 ​ SBA held ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ for ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands) ​ investment ​ Commercial ​ Residential ​ Consumer ​ Total Allowance for loan losses ending balance: ​ ​ ​ ​ ​ Individually evaluated for impairment ​ $ 41 ​ $ 373 ​ $ — ​ $ — ​ $ 414 Collectively evaluated for impairment ​ 1,038 ​ 9,349 ​ 4,254 ​ 1,340 ​ 15,981 Total ​ $ 1,079 ​ $ 9,722 ​ $ 4,254 ​ $ 1,340 ​ $ 16,395 Loan ending balances: ​ ​ ​ ​ ​ Individually evaluated for impairment ​ $ 1,105 ​ $ 1,234 ​ $ — ​ $ — ​ $ 2,339 Collectively evaluated for impairment ​ 34,662 ​ 763,798 ​ 467,706 ​ 143,524 ​ 1,409,690 Total ​ $ 35,767 ​ $ 765,032 ​ $ 467,706 ​ $ 143,524 ​ $ 1,412,029 ​ Changes in Methodology The Company did not make any changes to its allowance for loan losses methodology in the current period. Reserve for Unfunded Loan Commitments In addition to the allowance for loan losses, the Company maintains a reserve for unfunded loan commitments at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the reserve are made through other expense and applied to the reserve which is classified as other liabilities. At September 30, 2020, a $269 thousand commitment reserve was reported on the balance sheet as an “other liability”, compared to a $273 thousand commitment reserve at December 31, 2019, due to a larger loan portfolio requiring a larger general reserve.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	NOTE 10. New Accounting Pronouncements ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 was issued to replace the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. For public business entities, ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. In May 2019, FASB issued ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief." ASU 2019-05 was issued to address concerns with the adoption of ASU 2016-13. ASU 2019-05 gives entities the ability to irrevocable elect the fair value option in Subtopic 825-10 for certain existing financial assets upon transition to ASU 2016-03. Financial assets that are eligible for this fair value election are those that qualify under Subtopic 825-10 and are within the scope of Subtopic 326-10, "Financial Instruments - Credit Losses - Measured at Amortized Costs." An exception to this is held-to-maturity debt securities, which do not qualify for this transition election. The effective date for the amendment is the same as the effective date in ASU 2016-03. In November 2019, FASB issued ASU 2019-10, "Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates." ASU 2019-10 was issued to defer the effective dates for certain guidance in its Accounting Standard Codification ("ASC") for certain entities. The amendments in this update amend the mandatory effective dates for ASC 326, "Financial Instruments - Credit Losses", for entities eligible to be smaller reporting companies as defined by the SEC for fiscal years beginning after December 15, 2022, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. In November 2019, FASB issued ASU 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses." ASU 2019-11 was issued to address issues raise by stakeholders during the implementation of ASU 2016-13. ASU 2019-11 provides transition relief when adjusting the effective interest rate for troubled debt restructurings ("TDRs") that exist as of the adoption date, extends the disclosure relief in ASU 2019-04 to disclose accrued interest receivable balances separately from the amortized cost basis to additional disclosures involving amortized cost basis, and provides clarification regarding application of the guidance in paragraph 326-20-35-6 for financial assets secured by collateral maintenance provisions that provides a practical expedient to measure the estimate of expected credit losses by comparing the amortized cost basis of a financial asset and the fair value of collateral securing the financial asset as of the reporting date. The effective date and transition requirements for the amendment are the same as the effective date and transition requirements in ASU 2016-13. ASU 2017-04, "Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 was issued in an effort to simplify accounting in a new standard. The amendments in this update require that an entity perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The amendment states that an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For public business entities, ASU 2017-04 is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performing on testing dates after January 1, 2017. The Company adopted this standard as of January 1, 2020. The adoption of this ASU did not have an impact on the Company’s consolidated financial statements since the fair values of our reporting units were not lower than their respective carrying amounts at the time of our goodwill impairment analysis. ASU 2019- 12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." ASU 2019-12 removes the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items and removes the exception to the interim period income tax accounting when a year-to-date loss exceeds the anticipated loss for the year. ASU 2019-12 also simplifies the accounting for income taxes by requiring that an entity recognize a franchise tax that is partially based on income as an income-based tax, that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill originally was recognized, and that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. For public business entities, ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020. ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force)." ASU 2020-01 clarifies that the observable price changes in orderly transactions that should be considered when applying the measurement alternative in accordance with ASC 321 include transactions that require it to either apply or discontinue the equity method of accounting under ASC 323. ASU 2020-01 also addresses questions about how to apply the guidance in Topic 815, “Derivatives and Hedging,” for certain forward contracts and purchased options to purchase securities that, upon settlement or exercise, would be accounted for under the equity method of accounting. The ASU clarifies that, for the purpose of applying ASC 815-10-15- 141(a), an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, the underlying securities would be accounted for under the equity method in ASC 323 or the fair value option in accordance with the financial instruments guidance in Topic 825, “Financial Instruments.” For public business entities, ASU 2020-01 is effective for interim and annual periods beginning after December 15, 2020. ASU 2020- 03, "Codification Improvement to Financial Instruments." ASU 2020-03 clarifies that all entities are required to provide the fair value option disclosures in paragraphs 825-10-50-24 through 50-32 of the FASB’s Accounting Standards Codification (ASC). ASU 2020-03 also clarifies that the contractual term of a net investment in a lease determined in accordance with ASC 842, “Leases,” should be the contractual term used to measure expected credit losses under ASC 326, “Financial Instruments – Credit Losses.” ASU 2020-03 also addresses amendments to ASC 860-20, “Transfers and Servicing – Sales of Financial Assets,” clarify that when an entity regains control of financial assets sold, an allowance for credit losses should be recorded in accordance with ASC 326. The effective date and transition requirements for the amendment are the same as the effective date and transition requirements in ASU 2016-13. ASU 2020- 04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." ASU 2020-04 provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance. ASU 2020-04 provides various optional expedients, including the following, for hedging relationships affected by reference rate reform, if certain criteria are met: ● An entity can change certain critical terms of the hedging instrument or hedged item or transaction without having to dedesignate the relationship. ● For fair value hedging relationships in which the designated interest rate is LIBOR or another rate that is expected to be discontinued, an entity may change the hedged risk to another permitted benchmark rate without dedesignating the relationship. ● For cash flow hedging relationships in which the designated hedged risk is LIBOR or another rate that is expected to be discontinued, an entity may assert that the occurrence of the hedged forecasted transaction remains probable. ● Certain qualifying conditions for the shortcut method and other methods that assume perfect effectiveness may be disregarded. ​ In addition, ASU 2020-04 permits an entity to make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that were classified as held to maturity before January 1, 2020. ASU 2020-04 was effective upon its issuance on March 12, 2020. However, it cannot be applied to contract modifications that occur after December 31, 2022. With certain exceptions, the ASU also cannot be applied to hedging relationships entered into or evaluated after that date. ​ ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity.” ASU 2020-06 was issued to address the complexities of its guidance for certain financial instruments with characteristics of liabilities and equity, including: ● Removing the accounting models that require beneficial conversion features or cash conversion features associated with convertible instruments to be recognized as a separate component of equity. ● Adding certain disclosure requirements for convertible instruments. ● Amending the guidance for the derivatives scope exception for contracts in an entity’s own equity. ● Simplifying the diluted earning per share calculation for certain situations. For public business entities, ASU 2020-06 is effective for interim and annual periods beginning after December 15, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging Activities	NOTE 11. Derivative Financial Instruments and Hedging Activities Derivative Financial Instruments The Company has derivative financial instruments in the form of interest rate swap agreements, which derive their value from underlying interest rates. These transactions involve both credit and market risk. The notional amounts are amounts on which calculations, payments, and the value of the derivatives are based. Notional amounts do not represent direct credit exposures. Direct credit exposure is limited to the net difference between the calculated amounts to be received and paid, if any. Such difference, which represents the fair value of the derivative instrument, is reflected on the Company’s balance sheet as other assets or other liabilities. The Company is exposed to credit-related losses in the event of nonperformance by the counterparties to any derivative agreement. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures, and does not expect any counterparties to fail their obligations. The Company deals only with primary dealers. Derivative instruments are generally either negotiated OTC contracts or standardized contracts executed on a recognized exchange. Negotiated OTC derivative contracts are generally entered into between two counterparties that negotiate specific agreement terms, including the underlying instrument, amount, exercise prices and maturity. Risk Management Policies – Hedging Instruments The primary focus of the Company’s asset/liability management program is to monitor the sensitivity of the Company’s net portfolio value and net income under varying interest rate scenarios to take steps to control its risks. On a quarterly basis, the Company evaluates the effectiveness of entering into any derivative agreement by measuring the cost of such an agreement in relation to the reduction in net portfolio value and net income volatility within an assumed range of interest rates. Interest Rate Risk Management – Cash Flow Hedging Instruments The Company has variable rate debt as a source of funds for use in the Company’s lending and investment activities and for other general business purposes. These debt obligations expose the Company to variability in interest payments due to changes in interest rates. If interest rates increase, interest expense increases. Conversely, if interest rates decrease, interest expense decreases. Management believes it is prudent to limit the variability of a portion of its interest payments and, therefore hedges its variable-rate interest payments. To meet this objective, management enters into interest rate swap agreements whereby the Company receives variable interest rate payments and makes fixed interest rate payments during the contract period. At September 30, 2020, the Company had interest rate swaps with a notional amount of $100.0 million, compared to a notional amount of $60.0 million at December 31, 2019, which were designated as cash flow hedging instruments. During the nine months ended September 30, 2020, the Company entered into two new swap agreements with notional values of $20.0 million each. A summary of the Company’s outstanding interest rate swap agreements used to hedge variable rate debt at September 30, 2020 and December 31, 2019, respectively is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ (In thousands, except percentages and years) September 30, 2020 December 31, 2019 Notional amount ​ $ 100,000 ​ $ 60,000 ​ Fair value ​ $ (1,293) ​ $ 238 ​ Weighted average pay rate ​ 1.19 % 1.42 % Weighted average receive rate ​ 1.10 % 2.19 % Weighted average maturity in years ​ 2.33 ​ 1.25 ​ Number of contracts ​ 6 ​ 4 ​ ​ During the three and nine months ended September 30, 2020, the Company received variable rate London Interbank Offered Rate ("LIBOR") payments from and paid fixed rates in accordance with its interest rate swap agreements. At September 30, 2020, the unrealized loss relating to interest rate swaps was recorded as a derivative liability, whereas at December 31, 2019, the unrealized gain relating to interest rate swaps was recorded as a derivative asset. Changes in the fair value of the interest rate swaps designated as hedging instruments of the variability of cash flows associated with long-term debt are reported in other comprehensive income. The following table presents the net losses recorded in other comprehensive income and the consolidated financial statements relating to the cash flow derivative instruments at September 30, 2020 and 2019, respectively: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ (In thousands) 2020 2019 ​ 2020 2019 ​ Unrealized gains (losses) relating to interest rate swaps $ 220 $ (177) ​ (1,530) (1,077) ​ ​

Employee Benefit Plans	NOTE 12. Employee Benefit Plans Stock Option Plans The Company has incentive and nonqualified option plans, which allow for the grant of options to officers, employees and members of the Board of Directors. Grants under the Company’s incentive and nonqualified option plans generally vest over 3 years and must be exercised within 10 years of the date of grant. Transactions under the Company’s stock option plans for the nine months ended September 30, 2020 are summarized in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ Weighted ​ average ​ ​ ​ ​ ​ ​ ​ average ​ remaining ​ Aggregate ​ ​ ​ ​ exercise ​ contractual ​ intrinsic ​ ​ Shares ​ price ​ life in years ​ value Outstanding at December 31, 2019 614,311 ​ $ 14.78 6.9 ​ $ 4,783,402 Options granted 101,000 ​ 20.39 ​ ​ ​ Options exercised (54,611) ​ 7.24 ​ ​ ​ Options forfeited (30,000) ​ 19.50 ​ ​ ​ Options expired — ​ — ​ ​ ​ Outstanding at September 30, 2020 630,700 ​ $ 16.11 6.8 ​ $ 689,468 Exercisable at September 30, 2020 ​ 367,869 ​ $ 12.90 5.4 ​ $ 689,468 ​ On April 25, 2019, the Company adopted the 2019 Equity Compensation Plan providing for grants of up to 500,000 shares to be allocated between incentive and non-qualified stock options, restricted stock awards, performance units and deferred stock. The Plan replaced all previously approved and established equity plans then currently in effect. As of September 30, 2020, 142,000 options and 32,900 shares of restricted stock have been awarded from the plan leaving 325,100 shares available for future grants. The fair values of the options granted during the three and nine months ended September 30, 2020 and 2019 were estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ ​ For the nine months ended September 30, ​ ​ 2020 2019 ​ 2020 2019 ​ Number of options granted ​ — ​ — ​ ​ 101,000 ​ 55,000 ​ Weighted average exercise price ​ $ — ​ $ — ​ ​ $ 20.39 ​ $ 20.61 ​ Weighted average fair value of options ​ $ — ​ $ — ​ ​ $ 5.54 ​ $ 6.21 ​ Expected life in years (1) ​ 0.00 ​ 0.00 ​ ​ 8.66 ​ 8.23 ​ Expected volatility (2) ​ — % — % ​ 27.13 % 27.08 % Risk-free interest rate (3) ​ — % — % ​ 1.55 % 2.55 % Dividend yield (4) ​ — % — % ​ 1.61 % 1.36 % ​ (1) The expected life of the options was estimated based on historical employee behavior and represents the period of time that options granted are expected to be outstanding. (2) The expected volatility of the Company’s stock price was based on the historical volatility over the period commensurate with the expected life of the options. (3) The risk-free interest rate is the U.S. Treasury rate commensurate with the expected life of the options on the date of grant. (4) The expected dividend yield is the projected annual yield based on the grant date stock price. Upon exercise, the Company issues shares from its authorized but unissued common stock to satisfy the options. The following table presents information about options exercised during the three and nine months ended September 30, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ ​ 2020 2019 2020 2019 ​ Number of options exercised ​ — ​ 4,800 ​ ​ 54,611 ​ 57,234 ​ Total intrinsic value of options exercised ​ $ — ​ $ 38,127 ​ $ 475,222 ​ $ 742,737 ​ Cash received from options exercised ​ $ — ​ $ 61,134 ​ $ 395,518 ​ $ 424,198 ​ Tax deduction realized from options ​ $ — ​ $ 11,491 ​ $ 139,216 ​ $ 223,453 ​ ​ The following table summarizes information about stock options outstanding and exercisable at September 30, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Options outstanding ​ Options exercisable ​ ​ ​ Weighted average Weighted ​ Weighted ​ ​ Options ​ remaining contractual ​ average ​ Options ​ average Range of exercise prices ​ outstanding ​ life (in years) ​ exercise price ​ exercisable ​ exercise price $0.00 - $6.00 44,000 1.7 ​ $ 5.65 44,000 ​ $ 5.65 $6.01 - $12.00 156,667 4.5 ​ 8.85 156,667 ​ 8.85 $12.01 - $18.00 92,533 7.5 ​ 15.86 57,533 ​ 15.61 $18.01 - $24.00 337,500 8.3 ​ 20.91 109,669 ​ 20.19 Total 630,700 6.8 ​ $ 16.11 367,869 ​ $ 12.90 ​ Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 718, “Compensation - Stock Compensation,” ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ ​ 2020 2019 ​ 2020 2019 ​ Compensation expense ​ $ 185,408 ​ $ 155,942 ​ $ 558,682 ​ $ 446,544 ​ Income tax benefit ​ $ 53,583 ​ $ 45,067 ​ $ 161,459 ​ $ 129,051 ​ ​ As of September 30, 2020, unrecognized compensation costs related to nonvested share-based compensation arrangements granted under the Company’s stock option plans totaled approximately $1.0 million.

Restricted Stock Awards Restricted stock is issued under the 2019 Equity Compensation Plan to reward employees and directors and to retain them by distributing stock over a period of time. Restricted stock awards granted to date vest over a period of 4 years and are recognized as compensation to the recipient over the vesting period. The awards are recorded at fair market value at the time of grant and amortized into salary expense on a straight line basis over the vesting period.

That cost is expected to be recognized over a weighted average period of 2.4 years. 401(k) Savings Plan The Bank has a 401(k) savings plan covering substantially all employees. Under the Plan, an employee can contribute up to 80 percent of their salary on a tax deferred basis. The Bank may also make discretionary contributions to the Plan. The Bank contributed $154 thousand and $150 thousand to the Plan during the three months ended September 30, 2020 and 2019, respectively, and $524 thousand and $490 thousand during the nine months ended September 30, 2020 and 2019, respectively. Deferred Compensation Plan The Company has a deferred compensation plan for both non-employee members of the Board of Directors of the Bank or an officer of the Bank chosen by the Board to participate. Directors of the Company have the option to elect to defer up to 100 percent of their respective retainer and Board of Director fees, and each chosen officer has the option to elect to defer up to 100 percent of their year-end cash bonuses and salary. Director and executive deferred compensation totaled $34 thousand and $22 thousand during the three months ended September 30, 2020 and 2019, respectively, and $555 thousand and $354 thousand during the nine months ended September 30, 2020 and 2019, respectively. The interest paid on the deferred balances totaled $35 thousand and $28 thousand during the three months ended September 30, 2020 and 2019, respectively, and $96 thousand and $78 thousand during the nine months ended September 30, 2020 and 2019 respectively. The deferred balances distributed totaled $3 thousand and $2 thousand during the three months ended September 30, 2020 and 2019, respectively, and $9 thousand during the nine months ended September 30, 2020 and 2019. Benefit Plans In addition to the 401(k) savings plan which covers substantially all employees, in 2015 the Company established an unfunded supplemental defined benefit plan to provide additional retirement benefits for the President and Chief Executive Officer (“CEO”) and certain key executives. On June 4, 2015, the Company approved the Supplemental Executive Retirement Plan (“SERP”) pursuant to which the President and CEO is entitled to receive certain supplemental nonqualified retirement benefits. On September 27, 2018 the Company approved a change in calculation of the Retirement Benefit payable under the SERP so that the Retirement Benefit shall be an amount equal to sixty percent (60%) of the average of the executive’s base salary for the thirty-six The President and CEO commenced vesting in this retirement benefit on January 1, 2014, and vests an additional three percent (3%) each year until fully vested on January 1, 2024. In the event that the President and CEO’s separation from service from the Company were to occur prior to full vesting, the President and CEO would be entitled to and shall be paid the vested portion of the retirement benefit calculated as of the date of separation from service. Notwithstanding the foregoing, upon a Change in Control, and provided that within 6 months following the Change in Control the President and CEO is involuntarily terminated for reasons other than “cause” or the President and CEO resigns for “good reason,” as such is defined in the SERP, or the President and CEO voluntarily terminates his employment after being offered continued employment in a position that is not a “Comparable Position,” as such is also defined in the SERP, the President and CEO shall become one hundred percent (100%) vested in the full retirement benefit. No contributions or payments have been made during the three and nine months ended September 30, 2020. The following table summarizes the components of the net periodic pension cost of the defined benefit plan recognized during the three and nine months ended September 30, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ (In thousands) 2020 2019 ​ 2020 2019 ​ Service cost ​ $ 32 ​ $ 235 ​ $ 95 ​ $ 454 ​ Interest cost ​ 37 ​ 36 ​ 111 ​ 99 ​ Amortization of prior service cost ​ 20 ​ 20 ​ 62 ​ 62 ​ Net periodic benefit cost ​ $ 89 ​ $ 291 ​ $ 268 ​ $ 615 ​ ​ The following table summarizes the changes in benefit obligations of the defined benefit plan during the nine months ended September 30, 2020 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, ​ (In thousands) 2020 2019 ​ Benefit obligation, beginning of year ​ $ 3,571 ​ $ 2,747 ​ Service cost ​ 95 ​ 454 ​ Interest cost ​ 111 ​ 99 ​ Benefit obligation, end of period ​ $ 3,777 ​ $ 3,300 ​ ​ On October 22, 2015, the Company entered into an Executive Incentive Retirement Plan (the “Plan”) with certain key executive officers other than the President and CEO. The Plan has an effective date of January 1, 2015. The Plan is an unfunded, nonqualified deferred compensation plan. For any Plan Year, a guaranteed annual Deferral Award percentage of seven and one half percent (7.5%) of the participant’s annual base salary will be credited to each Participant’s Deferred Benefit Account. A discretionary annual Deferral Award equal to seven and one half percent (7.5%) of the participant’s annual base salary may be credited to the Participant’s account in addition to the guaranteed Deferral Award, if the Bank exceeds the benchmarks set forth in the Annual Executive Bonus Matrix. The total Deferral Award shall never exceed fifteen percent (15%) of the participant’s base salary for any given Plan Year. Each Participant shall be one hundred percent (100%) vested in all Deferral Awards as of the date they are awarded. As of September 30, 2020, the Company had total year to date expenses of $53 thousand related to the Plan. The Plan is reflected on the Company’s balance sheet as accrued expenses. Certain members of management are also enrolled in a split-dollar life insurance plan with a post retirement death benefit of $250 thousand. Total expenses related to this plan were $1 thousand for the three months ended September 30, 2020 and 2019, and $4 thousand for the nine months ended September 30, 2020 and 2019, respectively.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital	NOTE 13. Regulatory Capital On September 17, 2019, the federal banking agencies issued a final rule providing simplified capital requirements for certain community banking organizations (banks and holding companies) with less than $10 billion in total consolidated assets, implementing provisions of The Economic Growth, Regulatory Relief, and Consumer Protection Act (“EGRRCPA”). Under the proposal, a qualifying community banking organization would be eligible to elect the community bank leverage ratio framework, or continue to measure capital under the existing Basel III requirements. The new rule was effective beginning January 1, 2020, and qualifying community banking organizations may elect to opt into the new community bank leverage ratio (“CBLR”) in their call report beginning in the first quarter of 2020. A qualifying community banking organization (“QCBO”) is defined as a bank, a savings association, a bank holding company or a savings and loan holding company with: ● A leverage capital ratio of greater than 9.0%; ● Total consolidated assets of less than $10.0 billion; ● Total off-balance sheet exposures (excluding derivatives other than credit derivatives and unconditionally cancelable commitments) of 25% or less of total consolidated assets; and ● Total trading assets and trading liabilities of 5% or less of total consolidated assets. ​ On April 6, 2020, the federal banking regulators, implementing the applicable provisions of the CARES Act, which modified the CBLR framework so that: (i) beginning in the second quarter 2020 and until the end of the year, a banking organization that has a leverage ratio of 8% or greater and meets certain other criteria may elect to use the CBLR framework; and (ii) community banking organizations will have until January 1, 2022, before the CBLR requirement is re-established at greater than 9%. Under the interim rules, the minimum CBLR will be 8% beginning in the second quarter and for the remainder of calendar year 2020, 8.5% for calendar year 2021, and 9% thereafter. The numerator of the CBLR is Tier 1 capital, as calculated under present rules. The denominator of the CBLR is the QCBO’s average assets, calculated in accordance with the QCBO’s Call Report instructions less assets deducted from Tier 1 capital. The Bank has opted into the CBLR, and will therefore not be required to comply with the Basel III capital requirements. As of September 30, 2020, the Bank’s CBLR was 9.62%, and the Company’s CBLR was 9.95%. The following table shows the CBLR ratio for the Company and the Bank for the period ended September 30, 2020, and the capital ratios for the Company and the Bank under Basel III requirements at December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company Bank Required for capital adequacy purposes (1) To be well-capitalized under prompt corrective action regulations At September 30, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CBLR 9.95 % 9.62 % 8.00 % 8.00 % At December 31, 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Leverage ratio ​ 10.59 % 10.15 % ​ 4.00 % 5.00 % CET1 11.59 % 11.81 % 4.50 % 6.50 % Tier I risk-based capital ratio 12.32 % 11.81 % 6.00 % 8.00 % Total risk-based capital ratio ​ 13.06 % 12.58 % 8.00 % 10.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) Excludes capital conservation buffer at December 31, 2019. ​

Leases
Leases	NOTE 14. Leases The Company follows ASU 2016-02, "Leases (Topic 842)," Operating leases in which the Bank is the lessee are recorded as right-of-use ("ROU") assets and lease liabilities and are included in Prepaid expenses and other assets and Accrued expenses and other liabilities, respectively, on the Bank’s Consolidated Balance Sheets. The Bank does not currently have any finance leases in which it is the lessee. Operating lease ROU assets represent the Bank’s right to use an underlying asset during the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate. The incremental borrowing rate was calculated for each lease by taking a variable rate FHLB ARC product (based on Libor plus a spread) and then swapping it to a fixed rate borrowing by adding a fixed mid swap rate for the desired term. The borrowing rate for each lease is unique based on the lease term. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in Occupancy expense in the Consolidated Statements of Income. The Bank’s leases relate primarily to bank branches, office space and equipment with remaining lease terms of generally 1 to 10 years. Certain lease arrangements contain extension options which typically range from 1 to 5 years at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. Certain real estate leases have lease payments that adjust based on annual changes in the Consumer Price Index ("CPI"). The leases that are dependent upon CPI are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Operating lease ROU assets totaled $2.5 million at September 30, 2020, compared to $2.8 million at December 31, 2019. As of September 30, 2020, operating lease liabilities totaled $2.5 million, compared to $2.8 million at December 31, 2019.

Accounting Policies [Abstract]
Overview	The accompanying Consolidated Financial Statements include the accounts of Unity Bancorp, Inc. (the "Parent Company") and its wholly-owned subsidiary, Unity Bank (the "Bank" or when consolidated with the Parent Company, the "Company"), and reflect all adjustments and disclosures which are generally routine and recurring in nature, and in the opinion of management, necessary for a fair presentation of interim results. The Bank has multiple subsidiaries used to hold part of its investment and loan portfolios and OREO properties. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current year presentation, with no impact on current earnings or shareholders’ equity. The financial information has been prepared in accordance with U.S. generally accepted accounting principles and has not been audited. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses during the reporting periods. Actual results could differ from those estimates. Amounts requiring the use of significant estimates include the allowance for loan losses, valuation of deferred tax and servicing assets, the carrying value of loans held for sale and other real estate owned, the valuation of securities and the determination of other-than-temporary impairment for securities and fair value disclosures. Management believes that the allowance for loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in economic conditions. The markets served by the Company have been significantly impacted by the COVID-19 pandemic, which started during the first quarter of 2020. The Company continues to assess the financial impact of the COVID-19 pandemic. The interim unaudited Consolidated Financial Statements included herein have been prepared in accordance with instructions for Form 10-Q and the rules and regulations of the Securities and Exchange Commission (“SEC”) and consist of normal recurring adjustments necessary for the fair presentation of interim results. The results of operations for the nine months ended September 30, 2020 are not necessarily indicative of the results which may be expected for the entire year. As used in this Form 10-Q, “we” and “us” and “our” refer to Unity Bancorp, Inc., and its consolidated subsidiary, Unity Bank, depending on the context. Certain information and financial disclosures required by U.S. generally accepted accounting principles have been condensed or omitted from interim reporting pursuant to SEC rules. Interim financial statements should be read in conjunction with the Company’s Consolidated Financial Statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
Other-Than-Temporary Impairment	Other-Than-Temporary Impairment The Company has a process in place to identify securities that could potentially incur credit impairment that is other-than-temporary. This process involves monitoring late payments, pricing levels, downgrades by rating agencies, key financial ratios, financial statements, revenue forecasts and cash flow projections as indicators of credit issues. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concern warrants such evaluation. This evaluation considers relevant facts and circumstances in evaluating whether a credit or interest rate-related impairment of a security is other-than-temporary. Relevant facts and circumstances considered include: (1) the extent and length of time the fair value has been below cost; (2) the reasons for the decline in value; (3) the financial position and access to capital of the issuer, including the current and future impact of any specific events and (4) for fixed maturity securities, the intent to sell a security or whether it is more likely than not the Company will be required to sell the security before the recovery of its amortized cost which, in some cases, may extend to maturity and for equity securities, our ability and intent to hold the security for a forecasted period of time that allows for the recovery in value. Management assesses its intent to sell or whether it is more likely than not that it will be required to sell a security before recovery of its amortized cost basis less any current-period credit losses. For debt securities that are considered other-than-temporarily impaired with no intent to sell and no requirement to sell prior to recovery of its amortized cost basis, the amount of the impairment is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between the security’s amortized cost basis and the present value of its expected future cash flows. The remaining difference between the security’s fair value and the present value of future expected cash flows is due to factors that are not credit related and is recognized in other comprehensive income. For debt securities where management has the intent to sell, the amount of the impairment is reflected in earnings as realized losses. The present value of expected future cash flows is determined using the best estimate cash flows discounted at the effective interest rate implicit to the security at the date of purchase or the current yield to accrete an asset-backed or floating rate security. The methodology and assumptions for establishing the best estimate cash flows vary depending on the type of security. The asset-backed securities cash flow estimates are based on bond specific facts and circumstances that may include collateral characteristics, expectations of delinquency and default rates, loss severity and prepayment speeds and structural support, including subordination and guarantees. The corporate bond cash flow estimates are derived from scenario-based outcomes of expected corporate restructurings or the disposition of assets using bond specific facts and circumstances including timing, security interests and loss severity.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans	Loans Loans Held for Sale Loans held for sale represent the guaranteed portion of Small Business Administration (“SBA”) loans, other than loans originated under the Paycheck Protection Program, and are reflected at the lower of aggregate cost or market value. The Company originates loans to customers under an SBA program that historically has provided for SBA guarantees of up to 90 percent of each loan. The Company generally sells the guaranteed portion of its SBA loans to a third party and retains the servicing, holding the nonguaranteed portion in its portfolio. The net amount of loan origination fees on loans sold is included in the carrying value and in the gain or loss on the sale. When sales of SBA loans do occur, the premium received on the sale and the present value of future cash flows of the servicing assets are recognized in income. All criteria for sale accounting must be met in order for the loan sales to occur; see details under the “Transfers of Financial Assets” heading above. Servicing assets represent the estimated fair value of retained servicing rights, net of servicing costs, at the time loans are sold. Servicing assets are amortized in proportion to, and over the period of, estimated net servicing revenues. Impairment is evaluated based on stratifying the underlying financial assets by date of origination and term. Fair value is determined using prices for similar assets with similar characteristics, when available, or based upon discounted cash flows using market-based assumptions. Any impairment, if temporary, would be reported as a valuation allowance. Serviced loans sold to others are not included in the accompanying Consolidated Balance Sheets. Income and fees collected for loan servicing are credited to noninterest income when earned, net of amortization on the related servicing assets. Loans Held to Maturity Loans held to maturity are stated at the unpaid principal balance, net of unearned discounts and deferred loan origination fees and costs. In accordance with the level yield method, loan origination fees, net of direct loan origination costs, are deferred and recognized over the estimated life of the related loans as an adjustment to the loan yield. Interest is credited to operations primarily based upon the principal balance outstanding. Loans are reported as past due when either interest or principal is unpaid in the following circumstances: fixed payment loans when the borrower is in arrears for two or more monthly payments; open end credit for two or more billing cycles; and single payment notes if interest or principal remains unpaid for 30 days or more. Nonperforming loans consist of loans that are not accruing interest as a result of principal or interest being in default for a period of 90 days or more or when the ability to collect principal and interest according to the contractual terms is in doubt (nonaccrual loans). When a loan is classified as nonaccrual, interest accruals are discontinued and all past due interest previously recognized as income is reversed and charged against current period earnings. Generally, until the loan becomes current, any payments received from the borrower are applied to outstanding principal until such time as management determines that the financial condition of the borrower and other factors merit recognition of a portion of such payments as interest income. Loans may be returned to an accrual status when the ability to collect is reasonably assured and when the loan is brought current as to principal and interest. Loans are charged off when collection is sufficiently questionable and when the Company can no longer justify maintaining the loan as an asset on the balance sheet. Loans qualify for charge-off when, after thorough analysis, all possible sources of repayment are insufficient. These include: 1) potential future cash flows, 2) value of collateral, and/or 3) strength of co-makers and guarantors. All unsecured loans are charged off upon the establishment of the loan’s nonaccrual status. Additionally, all loans classified as a loss or that portion of the loan classified as a loss is charged off. All loan charge-offs are approved by the Board of Directors. Troubled debt restructurings ("TDRs") occur when a creditor, for economic or legal reasons related to a debtor’s financial condition, grants a concession to the debtor that it would not otherwise consider. These concessions typically include reductions in interest rate, extending the maturity of a loan, or a combination of both. Interest income on accruing TDRs is credited to operations primarily based upon the principal amount outstanding, as stated in the paragraphs above. The Company evaluates its loans for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The Company has defined impaired loans to be all TDRs and nonperforming loans individually evaluated for impairment. Impairment is evaluated in total for smaller-balance loans of a similar nature (consumer and residential mortgage loans), and on an individual basis for all other loans. Impairment of a loan is measured based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, or as a practical expedient, based on a loan’s observable market price or the fair value of collateral, net of estimated costs to sell, if the loan is collateral-dependent. If the value of the impaired loan is less than the recorded investment in the loan, the Company establishes a valuation allowance, or adjusts existing valuation allowances, with a corresponding charge to the provision for loan losses. For additional information on loans, see Note 8 to the Consolidated Financial Statements and the section titled "Loan Portfolio" under Item 2. Management’s Discussion and Analysis.
Allowance for Loan Losses and Reserve for Unfunded Loan Commitments	Allowance for Loan Losses and Reserve for Unfunded Loan Commitments The allowance for loan losses is maintained at a level management considers adequate to provide for probable loan losses as of the balance sheet date. The allowance is increased by provisions charged to expense and is reduced by net charge-offs. The level of the allowance is based on management’s evaluation of probable losses in the loan portfolio, after consideration of prevailing economic conditions in the Company’s market area, the volume and composition of the loan portfolio, and historical loan loss experience. The allowance for loan losses consists of specific reserves for individually impaired credits and TDRs, reserves for nonimpaired loans based on historical loss factors and reserves based on general economic factors and other qualitative risk factors such as changes in delinquency trends, industry concentrations or local/national economic trends. This risk assessment process is performed at least quarterly, and, as adjustments become necessary, they are realized in the periods in which they become known. Although management attempts to maintain the allowance at a level deemed adequate to provide for probable losses, future additions to the allowance may be necessary based upon certain factors including changes in market conditions and underlying collateral values. In addition, various regulatory agencies periodically review the adequacy of the Company’s allowance for loan losses. These agencies may require the Company to make additional provisions based on their judgments about information available to them at the time of their examination. The Company maintains an allowance for unfunded loan commitments that is maintained at a level that management believes is adequate to absorb estimated probable losses. Adjustments to the allowance are made through other expenses and applied to the allowance which is maintained in other liabilities. For additional information on the allowance for loan losses and unfunded loan commitments, see Note 9 to the Consolidated Financial Statements and the sections titled "Asset Quality" and "Allowance for Loan Losses and Reserve for Unfunded Loan Commitments" under Item 2. Management’s Discussion and Analysis.
Income Taxes	Income Taxes The Company accounts for income taxes according to the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates applicable to taxable income for the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation reserves are established against certain deferred tax assets when it is more likely than not that the deferred tax assets will not be realized. Increases or decreases in the valuation reserve are charged or credited to the income tax provision. When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that ultimately would be sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. The evaluation of a tax position taken is considered by itself and not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. Interest and penalties associated with unrecognized tax benefits would be recognized in income tax expense on the income statement.
New Accounting Pronouncements	ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 was issued to replace the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. For public business entities, ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. In May 2019, FASB issued ASU 2019-05, "Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief." ASU 2019-05 was issued to address concerns with the adoption of ASU 2016-13. ASU 2019-05 gives entities the ability to irrevocable elect the fair value option in Subtopic 825-10 for certain existing financial assets upon transition to ASU 2016-03. Financial assets that are eligible for this fair value election are those that qualify under Subtopic 825-10 and are within the scope of Subtopic 326-10, "Financial Instruments - Credit Losses - Measured at Amortized Costs." An exception to this is held-to-maturity debt securities, which do not qualify for this transition election. The effective date for the amendment is the same as the effective date in ASU 2016-03. In November 2019, FASB issued ASU 2019-10, "Financial Instruments - Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates." ASU 2019-10 was issued to defer the effective dates for certain guidance in its Accounting Standard Codification ("ASC") for certain entities. The amendments in this update amend the mandatory effective dates for ASC 326, "Financial Instruments - Credit Losses", for entities eligible to be smaller reporting companies as defined by the SEC for fiscal years beginning after December 15, 2022, including interim reporting periods within that reporting period. The Company is currently evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. In November 2019, FASB issued ASU 2019-11, "Codification Improvements to Topic 326, Financial Instruments - Credit Losses." ASU 2019-11 was issued to address issues raise by stakeholders during the implementation of ASU 2016-13. ASU 2019-11 provides transition relief when adjusting the effective interest rate for troubled debt restructurings ("TDRs") that exist as of the adoption date, extends the disclosure relief in ASU 2019-04 to disclose accrued interest receivable balances separately from the amortized cost basis to additional disclosures involving amortized cost basis, and provides clarification regarding application of the guidance in paragraph 326-20-35-6 for financial assets secured by collateral maintenance provisions that provides a practical expedient to measure the estimate of expected credit losses by comparing the amortized cost basis of a financial asset and the fair value of collateral securing the financial asset as of the reporting date. The effective date and transition requirements for the amendment are the same as the effective date and transition requirements in ASU 2016-13. ASU 2017-04, "Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 was issued in an effort to simplify accounting in a new standard. The amendments in this update require that an entity perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The amendment states that an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. For public business entities, ASU 2017-04 is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performing on testing dates after January 1, 2017. The Company adopted this standard as of January 1, 2020. The adoption of this ASU did not have an impact on the Company’s consolidated financial statements since the fair values of our reporting units were not lower than their respective carrying amounts at the time of our goodwill impairment analysis. ASU 2019- 12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." ASU 2019-12 removes the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items and removes the exception to the interim period income tax accounting when a year-to-date loss exceeds the anticipated loss for the year. ASU 2019-12 also simplifies the accounting for income taxes by requiring that an entity recognize a franchise tax that is partially based on income as an income-based tax, that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill originally was recognized, and that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. For public business entities, ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020. ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force)." ASU 2020-01 clarifies that the observable price changes in orderly transactions that should be considered when applying the measurement alternative in accordance with ASC 321 include transactions that require it to either apply or discontinue the equity method of accounting under ASC 323. ASU 2020-01 also addresses questions about how to apply the guidance in Topic 815, “Derivatives and Hedging,” for certain forward contracts and purchased options to purchase securities that, upon settlement or exercise, would be accounted for under the equity method of accounting. The ASU clarifies that, for the purpose of applying ASC 815-10-15- 141(a), an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, the underlying securities would be accounted for under the equity method in ASC 323 or the fair value option in accordance with the financial instruments guidance in Topic 825, “Financial Instruments.” For public business entities, ASU 2020-01 is effective for interim and annual periods beginning after December 15, 2020. ASU 2020- 03, "Codification Improvement to Financial Instruments." ASU 2020-03 clarifies that all entities are required to provide the fair value option disclosures in paragraphs 825-10-50-24 through 50-32 of the FASB’s Accounting Standards Codification (ASC). ASU 2020-03 also clarifies that the contractual term of a net investment in a lease determined in accordance with ASC 842, “Leases,” should be the contractual term used to measure expected credit losses under ASC 326, “Financial Instruments – Credit Losses.” ASU 2020-03 also addresses amendments to ASC 860-20, “Transfers and Servicing – Sales of Financial Assets,” clarify that when an entity regains control of financial assets sold, an allowance for credit losses should be recorded in accordance with ASC 326. The effective date and transition requirements for the amendment are the same as the effective date and transition requirements in ASU 2016-13. ASU 2020- 04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." ASU 2020-04 provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance. ASU 2020-04 provides various optional expedients, including the following, for hedging relationships affected by reference rate reform, if certain criteria are met: ● An entity can change certain critical terms of the hedging instrument or hedged item or transaction without having to dedesignate the relationship. ● For fair value hedging relationships in which the designated interest rate is LIBOR or another rate that is expected to be discontinued, an entity may change the hedged risk to another permitted benchmark rate without dedesignating the relationship. ● For cash flow hedging relationships in which the designated hedged risk is LIBOR or another rate that is expected to be discontinued, an entity may assert that the occurrence of the hedged forecasted transaction remains probable. ● Certain qualifying conditions for the shortcut method and other methods that assume perfect effectiveness may be disregarded. ​ In addition, ASU 2020-04 permits an entity to make a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that were classified as held to maturity before January 1, 2020. ASU 2020-04 was effective upon its issuance on March 12, 2020. However, it cannot be applied to contract modifications that occur after December 31, 2022. With certain exceptions, the ASU also cannot be applied to hedging relationships entered into or evaluated after that date. ​ ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity.” ASU 2020-06 was issued to address the complexities of its guidance for certain financial instruments with characteristics of liabilities and equity, including: ● Removing the accounting models that require beneficial conversion features or cash conversion features associated with convertible instruments to be recognized as a separate component of equity. ● Adding certain disclosure requirements for convertible instruments. ● Amending the guidance for the derivatives scope exception for contracts in an entity’s own equity. ● Simplifying the diluted earning per share calculation for certain situations. For public business entities, ASU 2020-06 is effective for interim and annual periods beginning after December 15, 2021.
Benefit Plans	Benefit Plans In addition to the 401(k) savings plan which covers substantially all employees, in 2015 the Company established an unfunded supplemental defined benefit plan to provide additional retirement benefits for the President and Chief Executive Officer (“CEO”) and certain key executives. On June 4, 2015, the Company approved the Supplemental Executive Retirement Plan (“SERP”) pursuant to which the President and CEO is entitled to receive certain supplemental nonqualified retirement benefits. On September 27, 2018 the Company approved a change in calculation of the Retirement Benefit payable under the SERP so that the Retirement Benefit shall be an amount equal to sixty percent (60%) of the average of the executive’s base salary for the thirty-six The President and CEO commenced vesting in this retirement benefit on January 1, 2014, and vests an additional three percent (3%) each year until fully vested on January 1, 2024. In the event that the President and CEO’s separation from service from the Company were to occur prior to full vesting, the President and CEO would be entitled to and shall be paid the vested portion of the retirement benefit calculated as of the date of separation from service. Notwithstanding the foregoing, upon a Change in Control, and provided that within 6 months following the Change in Control the President and CEO is involuntarily terminated for reasons other than “cause” or the President and CEO resigns for “good reason,” as such is defined in the SERP, or the President and CEO voluntarily terminates his employment after being offered continued employment in a position that is not a “Comparable Position,” as such is also defined in the SERP, the President and CEO shall become one hundred percent (100%) vested in the full retirement benefit.
Leases	The Company follows ASU 2016-02, "Leases (Topic 842)," Operating leases in which the Bank is the lessee are recorded as right-of-use ("ROU") assets and lease liabilities and are included in Prepaid expenses and other assets and Accrued expenses and other liabilities, respectively, on the Bank’s Consolidated Balance Sheets. The Bank does not currently have any finance leases in which it is the lessee. Operating lease ROU assets represent the Bank’s right to use an underlying asset during the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate. The incremental borrowing rate was calculated for each lease by taking a variable rate FHLB ARC product (based on Libor plus a spread) and then swapping it to a fixed rate borrowing by adding a fixed mid swap rate for the desired term. The borrowing rate for each lease is unique based on the lease term. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in Occupancy expense in the Consolidated Statements of Income. The Bank’s leases relate primarily to bank branches, office space and equipment with remaining lease terms of generally 1 to 10 years. Certain lease arrangements contain extension options which typically range from 1 to 5 years at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. Certain real estate leases have lease payments that adjust based on annual changes in the Consumer Price Index ("CPI"). The leases that are dependent upon CPI are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability.

Average Recorded Investments in Impaired Loans and Related Amount of Interest Recognized	The following table presents the average recorded investments in impaired loans and the related amount of interest recognized during the time period in which the loans were impaired for the three and nine months ended September 30, 2020 and 2019. The average balances are calculated based on the month-end balances of impaired loans. When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual status, all payments are applied to principal under the cost recovery method, and therefore no interest income is recognized. The interest income recognized on impaired loans noted below represents primarily accruing TDRs and nominal amounts of income recognized on a cash basis for well-collateralized impaired loans. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ ​ ​ 2020 ​ 2019 ​ ​ ​ ​ Interest ​ ​ Interest ​ ​ ​ ​ ​ ​ income ​ ​ ​ ​ income ​ ​ ​ Average ​ recognized ​ Average ​ recognized ​ ​ ​ recorded ​ on impaired ​ recorded ​ on impaired ​ (In thousands) ​ investment ​ loans ​ investment ​ loans ​ SBA loans held for investment (1) ​ $ 1,928 ​ $ 24 ​ $ 255 ​ $ 4 ​ Commercial loans ​ ​ ​ ​ ​ ​ Commercial other ​ 50 ​ — ​ 700 ​ 3 ​ Commercial real estate ​ 1,081 ​ 26 ​ 831 ​ 9 ​ Commercial real estate construction ​ ​ — ​ ​ 33 ​ ​ — ​ ​ — ​ Residential mortgage loans ​ ​ 4,850 ​ ​ 63 ​ ​ — ​ ​ — ​ Consumer loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 760 ​ ​ 29 ​ ​ — ​ ​ — ​ Consumer other ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ Total ​ $ 8,669 ​ $ 175 ​ $ 1,786 ​ $ 16 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the nine months ended September 30, ​ ​ 2020 ​ 2019 ​ ​ ​ Interest ​ ​ Interest ​ ​ ​ ​ ​ income ​ ​ ​ ​ income ​ ​ Average ​ recognized ​ Average ​ recognized ​ ​ recorded ​ on impaired ​ recorded ​ on impaired (In thousands) ​ investment ​ loans ​ investment ​ loans SBA loans held for investment (1) ​ $ 1,440 ​ $ 30 ​ $ 685 ​ $ 13 Commercial loans ​ ​ ​ ​ SBA 504 loans ​ 200 ​ 32 ​ — ​ — Commercial other ​ 51 ​ 25 ​ 236 ​ 3 Commercial real estate ​ 1,137 ​ 67 ​ 1,369 ​ 17 Commercial real estate construction ​ ​ — ​ ​ 33 ​ ​ — ​ ​ — Residential mortgage loans ​ ​ 5,533 ​ ​ 129 ​ ​ — ​ ​ — Consumer loans ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Home equity ​ ​ 536 ​ ​ 53 ​ ​ — ​ ​ — Consumer other ​ ​ 25 ​ ​ — ​ ​ — ​ ​ — Total ​ $ 8,922 ​ $ 369 ​ $ 2,290 ​ $ 33 ​ (1) Balances are reduced by the average amount guaranteed by the SBA of $687 thousand and $146 thousand for the nine months ended September 30, 2020 and 2019, respectively.
