Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION These consolidated financial statements include the accounts of Franklin Financial Network, Inc. (“FFN”), and its wholly-owned subsidiaries, Franklin Synergy Bank (“Franklin Synergy” or the “Bank”) and Franklin Synergy Risk Management, Inc. (collectively, the “Company”). Franklin Synergy Investments of Tennessee, Inc., Franklin Synergy Investments of Nevada, Inc., and Franklin Synergy Preferred Capital, Inc. are direct or indirect subsidiaries of the Bank and are included in these consolidated financial statements. Significant intercompany transactions and accounts are eliminated in consolidation. The Company provides financial services through its offices in Franklin, Brentwood, Spring Hill, Murfreesboro, Nashville, Nolensville, and Smyrna, Tennessee, as well as through its loan and deposit production location in Mt. Juliet, Tennessee. Its primary deposit products are checking, savings, and certificate of deposit accounts, and its primary lending products are commercial and residential construction, commercial, installment loans and lines secured by home equity. Substantially all loans are secured by specific items of collateral including commercial and residential real estate, business assets, and consumer assets. Commercial loans are expected to be repaid by cash flow from operations of businesses. The Company also focuses on electronic banking products such as internet banking, remote deposit capture and lockbox services. Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and in accordance with guidance provided by the SEC. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements reflect all normal and recurring adjustments considered necessary for a fair presentation. Transactions between the subsidiaries have been eliminated. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, and our Quarterly Report on Form 10-Q filed with the SEC on May 7, 2020. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. On January 21, 2020, the Company announced a strategic merger with FB Financial Corporation that is expected to close in the third quarter of 2020, with an anticipated closing date of August 15, 2020. Risks and Uncertainties The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. During the first quarter of 2020, the World Health Organization declared COVID-19 to be a global pandemic indicating that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The pandemic has caused significant disruptions in the U.S. economy, has disrupted banking and other financial activity in the areas in which the Company operates. The pandemic and its adverse consequences continued throughout the second quarter of 2020, and will likely present significant economic risks for at least the next several quarters. While there has been no material impact to the Company’s employees to date, COVID-19 could also potentially create widespread business continuity issues for the Company. The United States Congress, the President of the United States, and the Federal Reserve have taken several actions designed to cushion the economic fallout from the COVID-19 pandemic. Most notably, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law on March 27, 2020 as a $2.2 trillion legislative relief package. The goal of the CARES Act is to limit the impact of a potentially severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and medical providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts, together with other proposed and/or pending legislature and regulatory actions, are expected to have a material impact on the Company’s operations. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 escalates further or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. It is not possible at this time to know the full extent that the impact of COVID-19, and resulting measures to curtail its spread, could have on the Company’s operations, but such impacts could be material and adverse. Financial position and results of operations The Company’s fee income could be reduced due to the impacts of COVID-19. In keeping with guidance from regulators, the Company continues to work with COVID-19 affected customers to waive fees from a variety of sources, such as, but not limited to, insufficient funds and overdraft fees, ATM fees, account maintenance fees, etc. These reductions in fees are thought, at this time, to be temporary in conjunction with the length of the expected COVID-19 related economic crisis. At this time, the Company is unable to project the materiality of such an impact, but recognizes the breadth of the economic impact is likely to impact its fee income in future periods. The Company’s interest income could be reduced due to the impacts of COVID-19. In keeping with guidance from regulators, the Company is actively working with COVID-19 affected borrowers to defer their payments, interest, and fees. During the second quarter of 2020, the Company sold approximately $76.6 million of SBA PPP loans originated to a third party at a minimal discount. While interest and fees for any remaining SBA PPP loans will still accrue to income through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, interest income and fees accrued may need to be reversed. In such a scenario, interest income in future periods could be negatively impacted. At this time, the Company is unable to project the materiality of such an impact, but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. In an agreement with a third party provider, the Company sold substantially all of its Paycheck Protection Program (" PPP") loan portfolio that were originated and funded during the first and second quarter of 2020. This transaction allowed the Company to immediately recognize the origination fees paid by the Small Business Administration (“SBA”) during the second quarter of 2020. The Company no longer retains the servicing or other risks associated with the administration of the transferred loan portfolio. Lending operations and accommodations to borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation and as outlined in the CARES Act, the Company continues to execute a payment deferral program for its eligible clients that are adversely affected by the pandemic. Depending on the demonstrated need of the client, the Company is deferring either the full loan payment or the principal component of the loan payment, with the typical deferral period of 90 days . The majority of the Company’s first round of 90-day loan payment deferrals began to mature toward the end of the second quarter of 2020 and during the first part of the third quarter of 2020. The Company is working with its customers during this timeframe to determine if a second 90-day loan payment deferral is necessary. During the period ended June 30, 2020, interagency guidance and the CARES Act rules provided clarity to accounting for modifications whereby under certain circumstances, such modifications would not be considered troubled debt restructurings ("TDRs"). As of July 31, 2020, we have approximately 305 loans with a balance of approximately $478,000 that have returned to regular payment status, and we have approximately 101 loans with a balance of approximately $253,000 that remain on temporary payment deferral program. Credit Pertaining to the Company’s June 30, 2020 financial condition and results of operations, COVID-19 had an impact on the Company’s allowance for loan and lease losses (“ALLL”) and the resulting provision for loan losses were impacted by changes in economic conditions. Should economic conditions worsen, we could experience further increases in our ALLL and record additional provision expense. The execution of the payment deferral program discussed above improved our ratio of past due loans to total loans. It is possible that our asset quality measures could worsen at future measurement periods if the effects of COVID-19 are prolonged. Goodwill COVID-19 could cause a further and sustained decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform an additional goodwill impairment test and could result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or equity. Recently Adopted and Effective Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04 , “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment .” The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation and instead treats goodwill impairment as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. ASU 2017-04 became effective for us on January 1, 2020, and it did not have a material impact on the Company’s consolidated financial statements. The Company's policy is to test goodwill for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. During the period ended June 30, 2020, the economic turmoil and market volatility resulting from the COVID-19 crisis resulted in a decrease in the Company's stock price and market capitalization. Management believed such decrease was a triggering indicator requiring an interim goodwill impairment quantitative analysis. Under the new simplified guidance, the Company determined that none of its goodwill was impaired as of June 30, 2020. Management will continue to evaluate the economic conditions at future reporting periods for applicable changes. In August 2018, the FASB issued ASU No. 2018-13 , “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 became effective for us on January 1, 2020, and only revises disclosure requirements. It did not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-15 , “ Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract .” ASU 2018-15 clarifies certain aspects of ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract. ASU 2018-15 became effective for the Company on January 1, 2020, and it did not have a significant impact on the Company's consolidated financial statements. Status of New Accounting Standard for Accounting for Allowance for Credit Losses On January 1, 2020, ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , became effective for the Company which replaces the existing incurred loss impairment methodology ("ILM") for loans that are collectively evaluated for impairment with a methodology that reflects management’s best estimate of lifetime expected credit losses and requires consideration of reasonable and supportable economic forecasts to develop a lifetime credit loss estimate. Topic 326 requires additional qualitative and quantitative disclosure to allow users to better understand the credit risk within the portfolio and the methodologies for determining the allowance for credit losses ("ACL"). The Cumulative Expected Credit Loss ("CECL") standard also simplifies the accounting model for purchased credit impaired loans. Additionally, Topic 326 requires expected credit losses on available-for-sale ("AFS") debt securities be recorded as an ACL. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may utilize an assumption of zero credit losses. In accordance with Section 4014 of the CARES Act, the Company deferred implementation of CECL and thus elected to continue to utilize the ILM to calculate loan loss reserves in the first and second quarters 2020. The temporary deferral of CECL will remain effective until the earlier of the termination of the national emergency declaration concerning the COVID-19 pandemic or December 31, 2020, with an effective retrospective implementation date of January 1, 2020. There is increased uncertainty on the local, regional, and national economy as a result of local and state stay-at-home orders, as well as relief measures provided at a national, state, and local level. The Company has taken actions to mitigate the impact or potential prospective credit losses including permitting short-term payment deferrals to current customers. These conditions significantly impact management’s determination of a reasonable and supportable forecast, an essential requirement in the calculation of expected credit losses under CECL methodology. The Company believes that the deferral will provide time to better assess the impact of the COVID-19 pandemic on the expected lifetime credit losses. Management will continue to measure and monitor the estimated impacts of CECL adoption through continued parallel testing of model simulations based on our portfolio composition and current expectations of future economic conditions. The Company’s CECL implementation efforts will remain in process in order to adequately comply with the provisions of CECL once the deferral period ceases.

As of June 30, 2020, management does not intend to sell and it is more likely than not that management will not be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates and other market conditions. The fair value is expected to recover as the bonds approach maturity.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans as well as non-homogeneous residential real estate loans. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. COVID-19 Supplemental information. The loan modifications and payment deferrals established in accordance with the CARES Act and interagency guidance disclosed in Note 1 did not result in immediate credit risk modifications. The impacted credits will continue to be monitored and assessed as the sustained impact of COVID-19 becomes better understood. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass-rated loans. The following table excludes deferred loan fees and includes PCI loans, which are included in the “Substandard” column. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows as of June 30, 2020 and December 31, 2019: Pass Special Substandard Total June 30, 2020 Construction and land development $ 644,946 $ — $ 335 $ 645,281 Commercial real estate: Nonfarm, nonresidential 958,145 6,974 4,751 969,870 Other 47,559 — — 47,559 Residential real estate: Closed-end 1-4 family 422,128 765 1,893 424,786 Other 182,979 — 3,767 186,746 Commercial and industrial 488,215 597 31,601 520,413 Consumer and other 3,570 — — 3,570 $ 2,747,542 $ 8,336 $ 42,347 $ 2,798,225 Pass Special Substandard Total December 31, 2019 Construction and land development $ 591,293 $ 248 $ — $ 591,541 Commercial real estate: Nonfarm, nonresidential 941,260 997 1,764 944,021 Other 49,891 — — 49,891 Residential real estate: Closed-end 1-4 family 452,363 825 2,732 455,920 Other 185,170 — 2,511 187,681 Commercial and industrial 539,442 943 42,256 582,641 Consumer and other 4,769 — — 4,769 $ 2,764,188 $ 3,013 $ 49,263 $ 2,816,464 Troubled Debt Restructurings (TDRs) As of June 30, 2020, the Company’s loan portfolio contains four loans that have been modified as TDRs with a balance of $4,303. Three loans with a balance of $3,992 were added as TDRs during the second quarter of 2020.

The Company has one finance lease with a lease term through 2035. In February 2020, the Company purchased the properties at Columbia Avenue and 120 9th Avenue in Franklin, Tennessee, therefore ending these lease agreements that represented approximately $19,000 and $20,000 in right-of-use assets and lease liabilities, respectively. In May 2020, the Company added one finance lease for a branch in Williamson County, Tennessee that relocated that added $1,627 in right-of-use assets and $1,618 in lease liabilities. In May 2020, a finance lease for an office space located in Williamson County, Tennessee was terminated and therefore decreased right-of-use assets and lease liabilities by $2,751 and $2,903, respectively.

SHARE-BASED PAYMENTS	Jun. 30, 2020
Equity [Abstract]
SHARE-BASED PAYMENTS	SHARE-BASED PAYMENTSThe Company has two share based compensation plans as described below. Total compensation cost that has been charged against income for those plans was $1,442 and $2,954 for the three and six months ended June 30, 2020 and $1,513 and $2,842 for the three and six months ended June 30, 2019. The total income tax benefit and expense, which is shown on the Consolidated Statements of Income was an increase of income tax expense of $210 and benefit of $3 for the three and six months ended June 30, 2020, respectively, and was a benefit of $92 and $205 for the three and six months ended June 30, 2019, respectively. Stock Options : The Company’s 2007 Omnibus Equity Incentive Plan (the “2007 Plan”), as amended and shareholder-approved, provided for authorized shares up to 4,000,000. The 2007 Plan provided that no options intended to be ISOs may be granted after April 9, 2017. As a result, the Company’s board of directors approved, and recommended to its shareholders for approval, an equity incentive plan, the 2017 Omnibus Equity Incentive Plan which the Company’s shareholders approved at the 2017 annual meeting of shareholders. On April 12, 2018, the Company’s Board of Directors approved the Amended and Restated 2017 Omnibus Equity Incentive Plan (the “Amended and Restated 2017 Plan”) to make certain changes in response to feedback received from the Company's shareholders. The terms of the Amended and Restated 2017 Plan are substantially similar to the terms of the 2007 Plan it was intended to replace. The Amended and Restated 2017 Plan provides for authorized shares up to 3,500,000. At June 30, 2020, there were 2,410,666 authorized shares available for issuance under the Amended and Restated 2017 Plan. Employee, organizer and director stock option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant; those option awards have a 10 year contractual term with varying vesting requirements. The Company assigns discretion to its Compensation Committee to make grants either as qualified incentive stock options or as non-qualified stock options. All employee grants are intended to be treated as qualified incentive stock options, if allowable. All other grants are expected to be treated as non-qualified. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected stock price volatility is based on historical volatilities of the Company. The Company uses historical data to estimate option exercise and post-vesting termination behavior. The expected term of options granted represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted during the six months ended June 30, 2020. The fair value of options granted during the six months ended June 30, 2019, was determined using the following weighted-average assumptions as of grant date. June 30, 2019 Risk-free interest rate 2.47 % Expected term 7 years Expected stock price volatility 30.64 % Dividend yield 0.57 % The weighted average fair value of options granted for the six months ended June 30, 2020 and 2019 were $0.00 and $9.78, respectively. A summary of the activity in the plans for the six months ended June 30, 2020 follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding at January 1, 2020 1,502,070 $ 22.39 Granted — — Exercised (76,489) 11.33 Forfeited, expired, or cancelled (19,252) 21.26 Outstanding at period end 1,406,329 $ 17.54 6.10 $ 4,993 Vested or expected to vest 1,336,013 $ 26.54 5.76 $ 4,743 Exercisable at period end 601,711 $ 17.49 5.76 $ 4,972 For the Six Months Ended 2020 2019 Stock options exercised: Intrinsic value of options exercised $ 1,399 $ 1,869 Cash received from options exercised 866 1,277 Tax benefit realized from option exercises 212 205 As of June 30, 2020, there was $2,271 of total unrecognized compensation cost related to non-vested stock options granted under the plans. The cost is expected to be recognized over a weighted-average period of 1.17 years. Restricted Stock and Restricted Stock Units : Additionally, the 2007 Plan and the Amended and Restated 2017 Plan each provides for the granting of restricted share awards and other performance related incentives. When the restricted shares are awarded, a participant receives voting and dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. In April 2019, the Company began awarding restricted stock units, which do not have voting rights or dividend rights until the restrictions have lapsed. These awards typically have a vesting period of three five A summary of activity for non-vested restricted share awards for the six months ended June 30, 2020 is as follows: Non-vested Shares Shares Weighted- Non-vested at January 1, 2020 90,992 $ 32.54 Granted — — Vested (48,599) 32.10 Forfeited (180) 31.75 Non-vested at June 30, 2020 42,213 Compensation expense associated with the restricted share awards is recognized on a straight-line basis over the time period that the restrictions associated with the awards lapse based on the total cost of the award at the grant date. As of June 30, 2020, there was $387 of total unrecognized compensation cost related to non-vested shares granted under the 2007 Plan and Amended and Restated 2017 Plan. The cost is expected to be recognized over a weighted-average period of 1 year. The Company began granting restricted stock units in 2019. The restricted stock units vest annually into common stock outstanding on the date of grant during the service period. The following table outlines restricted stock units that were outstanding, grouped by similar vesting criteria, as of June 30, 2020: Grant year Units Awarded Service period in years 2019 2,870 5.0 2019 109,373 3.0 2020 118,725 3.0 Stock compensation expense related with the restricted stock units for the three and six months ended June 30, 2020 was $717 and $1,399, respectively. Stock compensation expense related with the restricted stock units for the three and six months ended June 30, 2019 was $483 and $579, respectively. This stock compensation is recognized on a straight-line basis over the time period that the restrictions associated with the awards lapse based on the total cost of the award at the grant date. As of June 30, 2020 and 2019, there were $7,222 and $3,814 of total unrecognized compensation cost related to non-vested restricted stock units granted under the Amended and Restated 2017 Plan. The cost is expected to be recognized over a weighted-average period of 1.99 years.

REGULATORY CAPITAL MATTERS

REGULATORY CAPITAL MATTERS	Jun. 30, 2020
Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
REGULATORY CAPITAL MATTERS	REGULATORY CAPITAL MATTERSBanks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. Banks (Basel III rules) provide for counter cyclical capital requirements so that the required amount of capital increases in times of economic expansion and decreases in times of economic contraction, consistent with safety and soundness. Under the Basel III rules, banks must maintain a capital conservation buffer consisting of additional Common Equity Tier 1 Capital equal to 2.5% of risk-weighted assets above each of the required minimum capital levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying certain discretionary bonuses. This capital conservation buffer became fully effective for the Company as of January 1, 2019. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2020, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. Management believes that, as of June 30, 2020, the Company and Bank met all capital adequacy requirements to which they are subject. There are no conditions or events since that notification that management believes have changed the institution’s category. In October 2019, the federal bank regulatory agencies, or the Agencies, issued a final rule, the Community Bank Leverage Ratio Framework, the “Framework,” to simplify capital calculations for community banks. The Framework provides for a simple measure of capital adequacy for certain community banking organizations and is consistent with Section 201 of the Economic Growth, Regulatory Relief and Consumer Protection Act. The Framework is optional and is designed to reduce burden by removing requirements for calculating and reporting risk-based capital ratios. Depository institutions and depository institution holding companies that have less than $10 billion in total consolidated assets and meet other qualifying criteria, including a leverage ratio of greater than 9%, are considered qualifying community banking organizations and are eligible to opt into the Framework. The final rule became effective January 1, 2020, and organizations that opt into the Framework and meet the criteria established by the rule can use the Framework for regulatory reports for the quarter ended March 31, 2020. In April 2020, the Agencies announced two interim final rules to provide relief associated with Section 4012 of the CARES Act. For institutions that elect the Framework, the interim rules temporarily lower the leverage ratio requirement to 8% for the second quarter of 2020 through the end of calendar year 2020 and to 8.5% for the 2021 calendar year. An institution will have until January 1, 2022 before the 9% leverage ratio requirement is re-established. The Company and the Bank have elected to opt into the Framework and will file their regulatory capital reports in accordance with the Framework’s guidance. For comparative purposes, the Company has included in the table below estimated regulatory capital ratios for the Company and for the Bank as of June 30, 2020, and December 31, 2019, based on the Basel III Capital Rules discussed above.

Banking regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies.

DERIVATIVE INSTRUMENTS	Jun. 30, 2020
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as hedges, the gain or loss is recognized in current earnings. Derivatives designated as fair value hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. During 2019, the Company entered into 16 swap transactions with a notional amount of $101,205 designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate securities. As of June 30, 2020, there were no additional swap transactions during 2020. A summary of the Company's fair value hedge relationships as of June 30, 2020 and December 31, 2019 are as follows (in thousands): June 30, 2020 December 31, 2019 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value Notional Amount Estimated Fair Value Liability derivative Interest rate swap agreements - securities Other liabilities 6.55 2.527% 3 month LIBOR $ 101,205 $ 14,068 $ 101,205 $ 4,954 The effects of fair value hedge relationships reported in interest income on securities on the consolidated statements of income for the three months ended June 30, 2020 and 2019 were as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, Gain (loss) on fair value hedging relationship 2020 2019 2020 2019 Interest rate swap agreements - securities: Hedged items $ 706 $ 3,615 $ 9,114 $ 4,733 Derivative designated as hedging instruments (706) (3,615) (9,114) (4,733) The following amounts were recorded on the balance sheet related to cumulative basis adjustments for fair value hedges at June 30, 2020: Carrying Amount of the Hedged Assets (in thousands) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets Line item on the balance sheet June 30, 2020 December 31, 2019 June 30, 2020 December 31, 2019 Securities available-for-sale $ 101,205 $ 101,205 $ 9,114 $ 4,954 Derivatives designated as cash flow hedges For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. The Company uses cash flow hedge relationships in an effort to manage future interest rate exposure. The hedging strategy converts the LIBOR-based variable interest rate on forecasted borrowings to a fixed interest rate and is used in an effort to protect the Company from floating interest rate variability. A summary of the Company's cash flow hedge relationships as of June 30, 2020 and December 31, 2019 are as follows (in thousands): June 30, 2020 December 31, 2019 Balance Sheet Location Weighted Average Remaining Maturity (In Years) Weighted Average Pay Rate Receive Rate Notional Amount Estimated Fair Value Notional Amount Estimated Fair Value Liability derivatives Interest rate swap agreements Other liabilities 2.1 2.232% 1 month LIBOR $ 100,000 $ 3,741 $ 100,000 $ 1,592 The effects of the Company's cash flow hedge relationships on the statement of comprehensive income (loss) during the three months ended June 30, 2020 and 2019 were as follows: Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss) Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss) Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Liability derivatives Interest rate swap agreements $ 142 $ (1,231) $ (1,587) $ (1,231) The cash flow hedges were determined to be highly effective during the periods presented and as a result qualify for hedge accounting treatment. The Company expects the hedges to continue to be highly effective and qualify for hedge accounting during the remaining terms of the swaps.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES We enter into certain off-balance sheet arrangements in the normal course of business to meet the financing needs of our customers. Those agreements involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheet. These off-balance sheet arrangements include commitments to make loans, credit lines and standby letters of credit which would impact our liquidity and capital resources to the extent customers accept or use these commitments. A commitment to extend credit is a formal agreement to lend funds to a client as long as there is no violation of any condition established under the agreement. The actual borrowing needs of our customers under these credit commitments have historically been lower than the contractual amount of the commitments. A significant portion of these commitments expire without being drawn upon. Actual borrowing needs of our customers may exceed our expected funding requirements, especially during a challenging economic environment when our client companies may be more dependent on our credit commitments due to the lack of available credit elsewhere, the increasing costs of credit, or the limited availability of financings from other sources. Any failure to meet our unfunded credit commitments in accordance with the actual borrowing needs of our customers may have a material adverse effect on our business, financial condition, results of operations or reputation. Commitments to make loans, credit lines and standby letters of credit involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. Off-balance-sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. The contractual amounts of financial instruments with off-balance sheet risk were as follows: June 30, 2020 December 31, 2019 Fixed Variable Total Fixed Variable Total Unused lines of credit $ 89,642 $ 637,394 $ 727,036 $ 89,040 $ 701,326 $ 790,366 Standby letters of credit 6,865 44,326 51,191 7,119 48,750 55,869 Mortgage loan commitments 136,235 — 136,235 48,999 — 48,999 Commitments to make loans are generally made for periods of over 365 days. At June 30, 2020, our loan commitments have interest rates ranging from 0.00% to 12.00% and maturity terms ranging from less than 1 year to 25 years. Of the $727,036 of unused lines of credit at June 30, 2020, the Company estimates approximately $294,290, or approximately 40.5%, are available to be drawn by customers without further approval by the Bank.

FAIR VALUE

FAIR VALUE	Jun. 30, 2020
Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Assets and liabilities measured at fair value on a recurring basis, including financial assets and liabilities for which the Company has elected the fair value option, are summarized below: Fair Value Measurements at June 30, Quoted Prices Significant Significant Financial Assets Securities available-for-sale Mortgage-backed securities-residential $ — $ 257,637 $ — Mortgage-backed securities-commercial — 15,592 — Corporate notes — 2,592 — State and political subdivisions — 228,056 — Total securities available-for-sale $ — $ 503,877 $ — Loans held for sale $ — $ 61,142 $ — Derivative assets $ — $ 2,269 $ — Financial Liabilities Derivative liabilities $ — $ 18,269 $ — Fair Value Measurements at December 31, Quoted Prices Significant Significant Financial Assets Securities available-for-sale Mortgage-backed securities-residential $ — $ 375,943 $ — Asset-backed securities — 17,780 — Corporate notes — 33,361 — State and political subdivisions — 225,048 — Total securities available for sale $ — $ 652,132 $ — Loans held-for-sale $ — $ 43,162 $ — Derivative assets $ — $ 225 $ — Financial Liabilities Derivative liabilities $ — $ 6,619 $ — The Company used the following methods and significant assumptions to estimate the fair value of financial instruments that are measured at fair value on a recurring basis: Securities : The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). Derivative assets : Included in other assets are certain assets carried at fair value and interest rate locks associated with the mortgage loan pipeline. The fair value of the mortgage loan pipeline rate locks is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate. These assets are valued using similar observable data that occurs in the market (Level 2). Loans Held For Sale: These loans are typically sold to an investor following loan origination and the fair value of such accounts are readily available based on direct quotes from investors or similar transactions experienced in the secondary loan market. Fair value adjustments, as well as realized gains and losses are recorded in current earnings. Fair value is determined by market prices or similar transactions adjusted for specific attributes of that loan (Level 2). Derivative liabilities : The Company has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions, and the cash flow hedge and interest rate locks associated with the funding for its mortgage loan originations. The fair value of these liabilities is based on pricing models that utilize observable market inputs (Level 2). There were no transfers between levels at June 30, 2020, and December 31, 2019 that had required write-downs to fair value. The following table presents assets measured at fair value on a non-recurring basis. There were no liabilities measured at fair value on a non-recurring basis as of June 30, 2020, and December 31, 2019.

As of June 30, 2020 and December 31, 2019, the only Level 3 assets with material unobservable inputs are associated with impaired loans and servicing rights. The table above includes those loans and servicing rights that are impaired and have a carrying balance as of June 30, 2020 and December 31, 2019. Impaired Loans : 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 pursuant to the contractual terms of the loan. Impairment is measured by estimating the fair value of the loan based on the present value of expected cash flows, the market price of the loan, or the underlying fair value of the loan's collateral. For real estate loans, fair value of the impaired loan's collateral is determined by third party appraisals, which are then adjusted for the estimated selling and closing costs related to liquidation of the collateral. For this asset class, the actual valuation methods (income, sales comparable, or cost) vary based on the status of the project or property. The unobservable inputs may vary depending on the individual assets with no one of the three methods being the predominant approach. The Company reviews the third party appraisal for appropriateness and adjusts the value downward to consider selling and closing costs, which typically is 10% of the appraised value. For non-real estate collateral loans, the unobservable inputs will vary depending on the credit. The fair value of the impaired loan's collateral may be determined using a third party appraisal, transactional values, discounted cash flows ("DCF"), sales comparisons, asset value, or aging reports, adjusted or discounted. As of June 30, 2020, the fair value of the non-real estate collateral loans was determined primarily based on the DCF method, resulting in a Level 3 fair value classification. Mortgage Servicing Rights : Fair value of mortgage servicing rights is based on valuation models that calculate the present value of estimated net cash flows based on industry market data. The valuation model incorporates assumptions that market participants would use in estimating future net cash flows resulting in a Level 3 classification. Financial Instruments Recorded Using Fair Value Option As of June 30, 2020, the unpaid principal balance of loans held for sale was $58,674 resulting in an unrealized gain of $2,468 included in gains on sale of loans. As of December 31, 2019, the unpaid principal balance of loans held for sale was $42,152, resulting in an unrealized gain of $1,010 included in gains on sale of loans. None of the loans as of June 30, 2020, or December 31, 2019 are 90 days or more past due or on nonaccrual. The following tables present the carrying amounts, estimated fair value and placement in the fair value hierarchy at June 30, 2020 and December 31, 2019.

The methods and assumptions not previously described used to estimate fair values are described as follows: (a) Cash and Cash Equivalents : The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. (b) Loans : Fair values of loans, excluding loans held for sale, are estimated as follows: In accordance with ASU 2016-01, the fair value of loans held for investment, excluding previously presented impaired loans measured at fair value on a non-recurring basis, is estimated using a cash flow projection methodology that relies on three primary assumptions: (1) the expected prepayment rate of loans; (2) the magnitude of future net losses based on expected default rate and severity of loss; and (3) the discount rate applicable to the expected cash flows of the loan portfolio. Loans are considered a Level 3 classification. ( c) Deposits: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 1 classification. The carrying amounts of fixed-term money market accounts approximate their fair values at the reporting date resulting in a Level 1 classification. Fair values for certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (d) Federal Funds Purchased and Repurchase Agreements: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within 90 days, approximate their fair values resulting in a Level 2 classification. (e) Federal Home Loan Bank Advances: The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. (f) Subordinated Notes : The fair values of the Company’s subordinated notes are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. (g) Accrued Interest Receivable/Payable : The carrying amounts of accrued interest approximate fair value resulting in a Level 1, Level 2 or Level 3 classification based on the asset/liability with which they are associated. (h) Off-balance Sheet Instruments : Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

SUBORDINATED DEBT ISSUANCE	SUBORDINATED DEBT ISSUANCE The Company’s subordinated notes, net of issuance costs, totaled $58,961 and $58,872 at June 30, 2020 and at December 31, 2019, respectively. For regulatory capital purposes, the subordinated notes are treated as Tier 2 capital, subject to certain limitations, and are included in total regulatory capital when calculating the Company’s total capital to risk weighted assets ratio as indicated in Note 7 of these consolidated financial statements. During 2016, the Company completed the issuance of $60,000 in principal amount of subordinated notes in two separate offerings. In March 2016, $40,000 of 6.875% fixed-to-floating rate subordinated notes (the “March 2016 Subordinated Notes”) were issued in a public offering to accredited institutional investors, and in June 2016, $20,000 of 7% fixed-to-floating rate subordinated notes (the “June 2016 Subordinated Notes”) were issued to certain accredited institutional investors in a private offering. The subordinated notes are unsecured and will rank at least equally with all of the Company’s other unsecured subordinated indebtedness and will be effectively subordinated to all of our secured debt to the extent of the value of the collateral securing such debt. The subordinated notes will be subordinated in right of payment to all of our existing and future senior indebtedness, and will rank structurally junior to all existing and future liabilities of our subsidiaries including, in the case of the Company’s bank subsidiary, its depositors, and any preferred equity holders of our subsidiaries. The holders of the subordinated notes may be fully subordinated to interests held by the U.S. government in the event that we enter into a receivership, insolvency, liquidation, or similar proceeding. The issuance costs related to the March 2016 Subordinated Notes amounted to $1,382 and are being amortized as interest expense over the ten ten The following table summarizes the terms of each subordinated note offering: March 2016 June 2016 Principal amount issued $40,000 $20,000 Maturity date March 30, 2026 July 1, 2026 Initial fixed interest rate 6.875% 7.00% Initial interest rate period 5 years 5 years First interest rate change date March 30, 2021 July 1, 2021 Interest payment frequency through year five Semiannually Semiannually Interest payment frequency after five years Quarterly Quarterly Interest repricing index and margin 3-month LIBOR plus 5.636% 3-month LIBOR plus 6.04% Repricing frequency after five years Quarterly Quarterly

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and in accordance with guidance provided by the SEC. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Principles of Consolidation	In the opinion of management, the accompanying unaudited consolidated financial statements reflect all normal and recurring adjustments considered necessary for a fair presentation. Transactions between the subsidiaries have been eliminated.
Recently Adopted Accounting Pronouncements	Recently Adopted and Effective Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04 , “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment .” The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation and instead treats goodwill impairment as the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance remains largely unchanged. ASU 2017-04 became effective for us on January 1, 2020, and it did not have a material impact on the Company’s consolidated financial statements. The Company's policy is to test goodwill for impairment annually on December 31 or on an interim basis if an event triggering impairment may have occurred. During the period ended June 30, 2020, the economic turmoil and market volatility resulting from the COVID-19 crisis resulted in a decrease in the Company's stock price and market capitalization. Management believed such decrease was a triggering indicator requiring an interim goodwill impairment quantitative analysis. Under the new simplified guidance, the Company determined that none of its goodwill was impaired as of June 30, 2020. Management will continue to evaluate the economic conditions at future reporting periods for applicable changes. In August 2018, the FASB issued ASU No. 2018-13 , “Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 became effective for us on January 1, 2020, and only revises disclosure requirements. It did not have a material impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-15 , “ Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract .” ASU 2018-15 clarifies certain aspects of ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract. ASU 2018-15 became effective for the Company on January 1, 2020, and it did not have a significant impact on the Company's consolidated financial statements. Status of New Accounting Standard for Accounting for Allowance for Credit Losses On January 1, 2020, ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , became effective for the Company which replaces the existing incurred loss impairment methodology ("ILM") for loans that are collectively evaluated for impairment with a methodology that reflects management’s best estimate of lifetime expected credit losses and requires consideration of reasonable and supportable economic forecasts to develop a lifetime credit loss estimate. Topic 326 requires additional qualitative and quantitative disclosure to allow users to better understand the credit risk within the portfolio and the methodologies for determining the allowance for credit losses ("ACL"). The Cumulative Expected Credit Loss ("CECL") standard also simplifies the accounting model for purchased credit impaired loans. Additionally, Topic 326 requires expected credit losses on available-for-sale ("AFS") debt securities be recorded as an ACL. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may utilize an assumption of zero credit losses. In accordance with Section 4014 of the CARES Act, the Company deferred implementation of CECL and thus elected to continue to utilize the ILM to calculate loan loss reserves in the first and second quarters 2020. The temporary deferral of CECL will remain effective until the earlier of the termination of the national emergency declaration concerning the COVID-19 pandemic or December 31, 2020, with an effective retrospective implementation date of January 1, 2020. There is increased uncertainty on the local, regional, and national economy as a result of local and state stay-at-home orders, as well as relief measures provided at a national, state, and local level. The Company has taken actions to mitigate the impact or potential prospective credit losses including permitting short-term payment deferrals to current customers. These conditions significantly impact management’s determination of a reasonable and supportable forecast, an essential requirement in the calculation of expected credit losses under CECL methodology. The Company believes that the deferral will provide time to better assess the impact of the COVID-19 pandemic on the expected lifetime credit losses. Management will continue to measure and monitor the estimated impacts of CECL adoption through continued parallel testing of model simulations based on our portfolio composition and current expectations of future economic conditions. The Company’s CECL implementation efforts will remain in process in order to adequately comply with the provisions of CECL once the deferral period ceases.
