SUMMARY OF SIGNIFICANT ACCOUNTI

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements of Investar Holding Corporation (the “Company”) have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include information or footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with GAAP. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the three and nine month periods ended September 30, 2019 is not necessarily indicative of the results that may be expected for the entire fiscal year. These statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2018 , including the notes thereto, which were included as part of the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 15, 2019. Nature of Operations Investar Holding Corporation, headquartered in Baton Rouge, Louisiana, provides full banking services, excluding trust services, through its wholly-owned banking subsidiary, Investar Bank, National Association (the “Bank”), a national bank. The Company’s primary markets are south Louisiana, southeast Texas and, as of November 1, 2019, southwest Alabama. At September 30, 2019 , the Company operated 22 full service branches located in Louisiana and 3 full service branches located in Texas, and had 285 employees. On November 1, 2019, the Company completed its acquisition of Bank of York in York, Alabama and added 2 additional branch locations in York and Livingston, Alabama, as well as a loan production office in Tuscaloosa, Alabama. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the allowance for loan losses may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Other estimates that are susceptible to significant change in the near term relate to the determination of other-than-temporary impairments of securities and the fair value of financial instruments. Investment Securities The Company’s investments in securities are accounted for in accordance with applicable guidance contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), which requires the classification of securities into one of the following categories: • Securities to be held to maturity (“HTM”): bonds, notes, and debentures for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. • Securities available for sale (“AFS”): available for sale securities consist of bonds, notes, and debentures that are available to meet the Company’s operating needs. These securities are reported at fair value. Unrealized holding gains and losses, net of tax, on AFS debt securities are reported as a net amount in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Realized gains and losses on the sale of debt securities are determined using the specific-identification method. The Company follows FASB guidance related to the recognition and presentation of other-than-temporary impairment. The guidance specifies that if an entity does not have the intent to sell a debt security and it is not more likely than not that the Company will be required to sell the security prior to recovery, the security would not be considered other-than-temporarily impaired unless there is a credit loss. When an entity does not intend to sell the security, and it is more likely than not that the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Equity Securities The Company is a member of the Federal Home Loan Bank (“FHLB”) system. Members of the FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, is restricted as to redemption, and is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Equity securities also include investments in our other correspondent banks including Independent Bankers Financial Corporation (“IBFC”) and First National Bankers Bank (“FNBB”) stock. These investments are carried at cost which approximates fair value. The balance of equity securities in our correspondent banks at September 30, 2019 and December 31, 2018 was $16.8 million and $11.9 million , respectively. In addition, equity securities include marketable securities in corporate stocks and mutual funds and totaled $2.0 million and $1.7 million at September 30, 2019 and December 31, 2018 , respectively. Loans The Company’s loan portfolio categories include real estate, commercial and consumer loans. Real estate loans are further categorized into construction and development, 1-4 family residential, multifamily, farmland and commercial real estate loans. The consumer loan category includes loans originated through indirect lending. Indirect lending, which is lending initiated through third-party business partners, is largely comprised of loans made through automotive dealerships. Loans for which management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off are stated at unpaid principal balances, adjusted by an allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Loans are ordinarily placed on nonaccrual when a loan is specifically determined to be impaired or when principal or interest is delinquent for 90 days or more; however, management may elect to continue the accrual when the estimated net realizable value of collateral is sufficient to cover the principal balance and the accrued interest. Any unpaid interest previously accrued on nonaccrual loans is reversed from income. Interest income, generally, is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on such loans are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans is recognized only to the extent of interest payments received. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period of repayment performance by the borrower. The Company considers a loan to be impaired when, based upon current information and events, it believes it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Company’s impaired loans include troubled debt restructurings and performing and non-performing loans for which full payment of principal or interest is not expected. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. The Company calculates an allowance required for impaired loans based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of its collateral. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance is required as a component of the allowance for loan losses. Changes to the valuation allowance are recorded as a component of the provision for loan losses. The Company follows the FASB accounting guidance on sales of financial assets, which includes participating interests in loans. For loan participations that are structured in accordance with this guidance, the sold portions are recorded as a reduction of the loan portfolio. Loan participations that do not meet the criteria are accounted for as secured borrowings. Allowance for Loan Losses The adequacy of the allowance for loan losses is determined in accordance with GAAP. The allowance for loan losses is estimated through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the loan balance is uncollectable. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount that management believes will be adequate to absorb probable losses inherent in the loan portfolio as of the balance sheet date based on evaluations of the collectability of loans and prior loan loss experience. The evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, review of specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Allowances for impaired loans are generally determined based on collateral values or the present value of estimated cash flows. Credits deemed uncollectible are charged to the allowance. Provisions for loan losses and recoveries on loans previously charged off are added to the allowance. Past due status is determined based on contractual terms. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. Based on management’s review and observations made through qualitative review, management may apply qualitative adjustments to determine loss estimates at a group and/or portfolio segment level as deemed appropriate. Management has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in its portfolio and portfolio segments. The Company utilizes an internally developed model that requires judgment to determine the estimation method that fits the credit risk characteristics of the loans in its portfolio and portfolio segments. Qualitative and environmental factors that may not be directly reflected in quantitative estimates include: asset quality trends, changes in loan concentrations, new products and process changes, changes and pressures from competition, changes in lending policies and underwriting practices, trends in the nature and volume of the loan portfolio, changes in experience and depth of lending staff and management and national and regional economic trends. Changes in these factors are considered in determining changes in the allowance for loan losses. The impact of these factors on the Company’s qualitative assessment of the allowance for loan losses can change from period to period based on management’s assessment of the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for loan losses. In the ordinary course of business, the Bank enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The reserve for unfunded lending commitments is included in accrued taxes and other liabilities in the consolidated balance sheet. At September 30, 2019 and December 31, 2018 the reserve for unfunded loan commitments was $102,000 and $66,000 , respectively. Acquisition Accounting Acquisitions are accounted for under the purchase method of accounting. Purchased assets and assumed liabilities are recorded at their respective acquisition date fair values, and identifiable intangible assets are recorded at fair value. If the consideration given exceeds the fair value of the net assets received, goodwill is recognized. If the fair value of the net assets received exceeds the consideration given, a bargain purchase gain is recognized. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Purchased loans acquired in a business combination are recorded at their estimated fair value as of the acquisition date. The fair value of loans acquired is determined using a discounted cash flow model based on assumptions regarding the amount and timing of principal and interest prepayments, estimated payments, estimated default rates, estimated loss severity in the event of defaults, and current market rates. Estimated credit losses are included in the determination of fair value; therefore, an allowance for loan losses is not recorded on the acquisition date. The fair value adjustment is amortized over the life of the loan using the effective interest method, except for those loans accounted for under ASC Topic 310-30, discussed below. The Company accounts for acquired impaired loans under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). An acquired loan is considered impaired when there is evidence of credit deterioration since origination and it is probable, at the date of acquisition, that we will be unable to collect all contractually required payments. ASC 310-30 prohibits the carryover of an allowance for loan losses for acquired impaired loans. Over the life of the acquired loans, we continually estimate the cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics. As of the end of each fiscal quarter, we evaluate the present value of the acquired loans using the effective interest rates. For any increases in cash flows expected to be collected, we adjust the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life, while we recognize a provision for loan loss in the consolidated statement of operations if the cash flows expected to be collected have decreased. Servicing Rights Primary servicing rights represent the Company’s right to service consumer automobile loans for third-party whole-loan sales and loans sold as participations. Primary servicing involves the collection of payments from individual borrowers and the distribution of these payments to the investors. The Company capitalizes the value expected to be realized from performing specified automobile servicing activities for others as automobile servicing rights (“ASRs”) when the expected future cash flows from servicing are projected to be more than adequate compensation for such activities. These capitalized servicing rights are purchased or retained upon sale of consumer automobile loans. The Company measures all consumer automobile servicing assets and liabilities at fair value. The Company defines servicing rights based on both the availability of market inputs and the manner in which the Company manages the risks of servicing assets and liabilities. The Company leverages all available relevant market data to determine the fair value of recognized servicing assets and liabilities. The Company calculates the fair value of ASRs using various assumptions including future cash flows, market discount rates, expected prepayments, servicing costs and other factors. A significant change in prepayments of loans in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of ASRs. For the nine months ended September 30, 2019 and 2018 , expected future cash flows from ASRs approximated adequate compensation for such activities. Accordingly, the Company has not recorded an asset or liability. There were no loan sales during the nine months ended September 30, 2019 or 2018 . Reclassifications Certain reclassifications have been made to the 2018 financial statements to be consistent with the 2019 presentation, if applicable. Concentrations of Credit Risk The Company’s loan portfolio consists of the various types of loans described in Note 5. Loans and Allowance for Loan Losses. Real estate or other assets secure most loans. The majority of loans have been made to individuals and businesses in the Company’s market of southeast Louisiana. Customers are dependent on the condition of the local economy for their livelihoods and servicing their loan obligations. The Company does not have any significant concentrations in any one industry or individual customer. Tax Cuts and Jobs Act Public law No. 115-97, known as the Tax Cuts and Jobs Act (the “Tax Act”), enacted on December 22, 2017, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. Also on December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for tax effects of the Tax Act. SAB 118 provided a measurement period of up to one year from the enactment date to complete the accounting. Any adjustments during the measurement period were included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments were determined. Based on the information available and interpretation of the rules, the Company recorded the impact of the reduction in the corporate tax rate and remeasurement of certain deferred tax assets and liabilities in the fourth quarter of 2017. An additional $0.6 million was expensed in the first quarter of 2018 due to the remeasurement of the Company’s deferred tax balance, resulting in an effective tax rate of 21.6% for the nine months ended September 30, 2018 . No additional adjustments were recorded during the measurement period, which ended December 31, 2018. Accounting Standards Adopted in 2019 In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718) , which expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services and supersedes Subtopic 505-50, “Equity – Equity-Based Payments to Non-Employees.” The Company adopted ASU 2018-07 on January 1, 2019. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , which amends the hedge accounting model in Topic 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. The amendments expand an entity’s ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This amended guidance was adopted on January 1, 2019, and, given the current level of derivatives designated as hedges, did not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities . The amendments in the ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company adopted ASU 2017-08 on January 1, 2019. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The ASU intends to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities and disclosing key information about leasing arrangements. The ASU requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers . The new lease guidance simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) may apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may also elect to apply the amendments in the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company historically has owned all property and equipment, although it entered an operating lease for a future branch location on December 31, 2018. The Company adopted the ASU on January 1, 2019, using the modified retrospective approach, and recognized a right-of-use asset and related lease liability of $1.2 million . At September 30, 2019 , the right-of-use asset and related lease liability were each $3.4 million . The adoption of this ASU did not have a significant impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements FASB ASC Topic 350 “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” Update No. 2018-15. In August 2018, the FASB issued ASU 2018-15. This ASU requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for the Company on January 1, 2020. Early adoption is permitted, including adoption in any interim period. The adoption of ASU 2018-15 is not expected to have a material impact on the Company’s consolidated financial statements. FASB ASC Topic 820 “Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” Update No. 2018-13. In August 2018, the FASB issued ASU 2018-13, which modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. ASU 2018-13 removes the disclosure requirement detailing the amount of and reasons for transfers between Level 1 and Level 2 and the valuation processes for Level 3 fair value measurements will be removed. In addition, this ASU modifies the disclosure requirement for investments in certain entities that calculate net asset value. Lastly, ASU 2018-13 adds a disclosure requirement for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. ASU 2018-13 is effective for the Company on January 1, 2020. Early adoption is permitted upon the issuance of ASU 2018-13. The removed and modified disclosures will be adopted on a retrospective basis, and the new disclosures will be adopted on a prospective basis. The adoption of ASU 2018-13 is not expected to have a material impact on the Company’s consolidated financial statements. FASB ASC Topic 350 “Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment” Update No. 2017-04. The FASB issued ASU No. 2017-04 in January 2017. The ASU simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Therefore, any carrying amount which exceeds the reporting unit’s fair value, up to the amount of goodwill recorded, will be recognized as an impairment loss. ASU 2017-04 will be effective for the Company on January 1, 2020. The amendment will be applied prospectively on or after the effective date. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Based on recent goodwill impairments tests, which did not require the application of Step 2, the Company does not expect the adoption of this ASU to have an immediate impact. FASB ASC Topic 326 “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments” Update No. 2016-13. The FASB issued ASU No. 2016-13 in June 2016. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. We are currently evaluating the potential impact of ASU 2016-13 on our financial statements. In that regard, we have formed a cross-functional working group, under the direction of our Chief Financial Officer and our Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, finance and information technology. We have developed an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. We have also selected a third-party vendor solution to assist us in the application of ASU 2016-13. The adoption of ASU 2016-13 is likely to result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses on debt securities. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios, as well as the prevailing economic conditions and forecasts, as of the adoption date. This amendment was originally effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In July 2019, the FASB proposed changes that would delay the effective date for smaller reporting companies, as defined by the SEC, and other non-SEC reporting entities. In October 2019, the FASB voted in favor of finalizing its proposal to delay the effective date of this standard to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016-13 will be effective for the Company on January 1, 2023. The Company expects to adopt the standard as soon as practicable, based upon progress on the implementation plan. Adoption prior to the revised effective date of January 1, 2023 is permitted by the ASU.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS Mainland Bank On March 1, 2019, the Company completed the acquisition of Mainland Bank (“Mainland”) located in Texas City, Texas. The Company acquired 100% of Mainland’s outstanding common shares for an aggregate merger consideration of 763,849 shares of the Company’s common stock, for a total of approximately $18.6 million . The acquisition of Mainland expanded the Company’s branch footprint into the greater Houston, Texas market. After fair value adjustments, including total adjustments of $0.1 million and $22,000 to other real estate owned and other liabilities, respectively, recorded in the three months ended September 30, 2019 , the acquisition added $128.5 million in total assets, $82.4 million in loans, and $107.6 million in deposits. As consideration paid was in excess of the net fair value of acquired assets, the Company recorded $4.5 million of goodwill. Goodwill resulted from a combination of synergies and cost savings, expansion into Texas with the addition of three branch locations, and enhanced products and services. The change in goodwill and other intangibles at September 30, 2019 compared to December 31, 2018 is primarily attributable to the goodwill and core deposit intangible recorded as a result of the Mainland acquisition. The table below shows the allocation of the consideration paid for Mainland’s common equity to the acquired identifiable assets and liabilities assumed and the goodwill generated from the transaction (dollars in thousands). The fair values listed below, primarily related to loans and deferred tax assets and liabilities, are subject to refinement for up to one year after the closing date of the acquisition as additional information becomes available. Purchase price: Stock issued $ 18,637 Fair value of assets acquired: Cash and cash equivalents 38,365 Loans 82,431 Other real estate owned 1,507 Bank premises and equipment 2,550 Core deposit intangible asset 2,439 Other assets 1,179 Total assets acquired 128,471 Fair value of liabilities acquired: Deposits 107,646 Repurchase agreements 4,684 Other liabilities 1,981 Total liabilities assumed 114,311 Fair value of net assets acquired 14,160 Goodwill $ 4,477 Fair value adjustments to assets acquired and liabilities assumed are generally amortized using the effective yield method over periods consistent with the average life, useful life and/or contractual term of the related assets and liabilities. The fair value of net assets acquired includes a fair value adjustment to loans as of the acquisition date. The adjustment for the acquired loan portfolio is based on current market interest rates, and the Company’s initial evaluation of credit losses identified. No loans acquired from Mainland were considered to be purchased credit impaired loans. The contractually required principal and interest payments of the loans acquired from Mainland is $91.9 million , of which $1.3 million is not expected to be collected. Supplemental Unaudited Pro Forma Information The following unaudited supplemental pro forma information is presented to show estimated results assuming Mainland was acquired as of January 1, 2018. These unaudited pro forma results are not necessarily indicative of the operating results that the Company would have achieved had it completed the acquisition as of January 1, 2018 and should not be considered representative of future operating results. The pro forma net income for the nine months ended September 30, 2019 excludes the tax-affected amount of $1.6 million of acquisition expenses recorded in noninterest expense by the Company and Mainland. Unaudited pro forma for the Three months ended September 30, Nine months ended September 30, (dollars in thousands) 2019 2018 2019 2018 Interest income $ 22,854 $ 20,231 $ 66,870 $ 58,300 Noninterest income 1,618 1,456 4,788 3,883 Net income 4,657 4,522 13,468 11,459 For the three months ended September 30, 2019 , Mainland added approximately $1.5 million , $77,000 , and $0.8 million to interest income, noninterest income, and net income, respectively. For the nine months ended September 30, 2019 , Mainland added approximately $3.6 million , $0.2 million , and $1.8 million to interest income, noninterest income, and net income, respectively. Acquisition Expense Acquisition related costs of $1.1 million are included in acquisition expenses in the accompanying consolidated statements of income for the nine months ended September 30, 2019 . These costs include system conversion and integrating operations charges as well as legal and consulting expenses related to the Mainland acquisition, as well as $0.2 million recorded in the three months ended September 30, 2019 related to the acquisition of Bank of York in York, Alabama, announced in July 2019.

The Company had no securities classified as trading as of September 30, 2019 or December 31, 2018 . The aggregate fair values and aggregate unrealized losses on securities whose fair values are below book values are summarized in the tables below. Unrealized losses are generally due to changes in interest rates. The Company has the intent to hold these securities either until maturity or a forecasted recovery, and it is more likely than not that the Company will not have to sell the securities before the recovery of their cost basis.

LOANS AND ALLOWANCE FOR LOAN LOSSES	LOANS AND ALLOWANCE FOR LOAN LOSSES The Company’s loan portfolio consists of the following categories of loans as of the dates presented (dollars in thousands). September 30, 2019 December 31, 2018 Construction and development $ 176,674 $ 157,946 1-4 Family 310,298 287,137 Multifamily 58,243 50,501 Farmland 24,629 21,356 Commercial real estate 693,150 627,004 Total mortgage loans on real estate 1,262,994 1,143,944 Commercial and industrial 293,152 210,924 Consumer 30,196 45,957 Total loans $ 1,586,342 $ 1,400,825 Unamortized premiums and discounts on loans, included in the total loans balances above, were $1.9 million and $1.4 million at September 30, 2019 and December 31, 2018 , respectively. Nonaccrual and Past Due Loans Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, we consider the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regard to our collateral position. Regulatory provisions would typically require the placement of a loan on nonaccrual status if (i) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or (ii) full payment of principal and interest is not expected. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period (at least six months) of repayment performance by the borrower. The table below provides an analysis of the aging of loans as of the dates presented (dollars in thousands).

Construction and Development - Construction and development loans are generally made for the purpose of acquisition and development of land to be improved through the construction of commercial and residential buildings. The successful repayment of these types of loans is generally dependent upon a commitment for permanent financing from the Company, or from the sale of the constructed property. These loans carry more risk than commercial or residential real estate loans due to the dynamics of construction projects, changes in interest rates, the long-term financing market, and state and local government regulations. One such risk is that loan funds are advanced upon the security of the property under construction, which is of uncertain value prior to the completion of construction. Thus, it is more difficult to evaluate accurately the total loan funds required to complete a project and to calculate related loan-to-value ratios. The Company attempts to minimize the risks associated with construction lending by limiting loan-to-value ratios as described above. In addition, as to speculative development loans, the Company generally makes such loans only to borrowers that have a positive pre-existing relationship with us. The Company manages risk by using specific underwriting policies and procedures for these types of loans and by avoiding excessive concentrations in any one business or industry. 1-4 Family - The 1-4 family portfolio mainly consists of residential mortgage loans to consumers to finance a primary residence. The majority of these loans are secured by properties located in the Company’s market areas and carry risks associated with the creditworthiness of the borrower and changes in the value of the collateral and loan-to-value-ratios. The Company manages these risks through policies and procedures such as limiting loan-to-value ratios at origination, employing experienced underwriting personnel, requiring standards for appraisers, and not making subprime loans. Multifamily - Multifamily loans are normally made to real estate investors to support permanent financing for multifamily residential income producing properties that rely on the successful operation of the property for repayment. This management mainly involves property maintenance and collection of rents due from tenants. This type of lending carries a lower level of risk, as compared to other commercial lending. In addition, underwriting requirements for multifamily properties are stricter than for other non-owner-occupied property types. The Company manages this risk by avoiding concentrations with any particular customer. Farmland - Farmland loans are often for land improvements related to agricultural endeavors and may include construction of new specialized facilities. These loans are usually repaid through the conversion to permanent financing, or if scheduled loan amortization begins, for the long-term benefit of the borrower’s ongoing operations. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Bank policies. Commercial Real Estate - Commercial real estate loans are extensions of credit secured by owner occupied and non-owner occupied collateral. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Bank policies. Repayment is commonly derived from the successful ongoing operations of the property. General market conditions and economic activity may impact the performance of these types of loans, including fluctuations in the value of real estate, new job creation trends, and tenant vacancy rates. The Company attempts to limit risk by analyzing a borrower’s cash flow and collateral value on an ongoing basis. The Company also typically requires personal guarantees from the principal owners of the property, supported by a review of their personal financial statements, as an additional means of mitigating our risk. The Company manages risk by avoiding concentrations in any one business or industry. Commercial and Industrial - Commercial and industrial loans receive similar underwriting treatment as commercial real estate loans in that the repayment source is analyzed to determine its ability to meet cash flow coverage requirements as set forth by Bank policies. Repayment of these loans generally comes from the generation of cash flow as the result of the borrower’s business operations. Commercial lending generally involves different risks from those associated with commercial real estate lending or construction lending. Although commercial loans may be collateralized by equipment or other business assets (including real estate, if available as collateral), the repayment of these types of loans depends primarily on the creditworthiness and projected cash flow of the borrower (and any guarantors). Thus, the general business conditions of the local economy and the borrower’s ability to sell its products and services, thereby generating sufficient operating revenue to repay us under the agreed upon terms and conditions, are the chief considerations when assessing the risk of a commercial loan. The liquidation of collateral, if any, is considered a secondary source of repayment because equipment and other business assets may, among other things, be obsolete or of limited resale value. The Company actively monitors certain financial measures of the borrower, including advance rate, cash flow, collateral value and other appropriate credit factors. Consumer - Consumer loans are offered by the Company in order to provide a full range of retail financial services to its customers and include auto loans, credit cards, and other consumer installment loans. Typically, the Company evaluates the borrower’s repayment ability through a review of credit scores and an evaluation of debt to income ratios. Repayment of consumer loans depends upon key consumer economic measures and upon the borrower’s financial stability, and is more likely to be adversely affected by divorce, job loss, illness and personal hardships than repayment of other loans. A shortfall in the value of any collateral also may pose a risk of loss to the Company for these types of loans. Indirect auto loans comprised the largest component of our consumer loans, representing 59% of our total consumer loans at September 30, 2019 . At September 30, 2019 , the weighted average remaining term of the indirect auto loan portfolio was 2.3 years . We exited the indirect auto lending business at the end of 2015. Credit Quality Indicators Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The following definitions are utilized for risk ratings, which are consistent with the definitions used in supervisory guidance: Pass - Loans not meeting the criteria below are considered pass. These loans have high credit characteristics and financial strength. The borrowers at least generate profits and cash flow that are in line with peer and industry standards and have debt service coverage ratios above loan covenants and our policy guidelines. For some of these loans, a guaranty from a financially capable party mitigates characteristics of the borrower that might otherwise result in a lower grade. Special Mention - Loans classified as special mention possess some credit deficiencies that need to be corrected to avoid a greater risk of default in the future. For example, financial ratios relating to the borrower may have deteriorated. Often, a special mention categorization is temporary while certain factors are analyzed or matters addressed before the loan is re-categorized as either pass or substandard. Substandard - Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the borrower or the liquidation value of any collateral. If deficiencies are not addressed, it is likely that this category of loan will result in the Bank incurring a loss. Where a borrower has been unable to adjust to industry or general economic conditions, the borrower’s loan is often categorized as substandard. Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as recorded assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off these assets. The table below presents the Company’s loan portfolio by category and credit quality indicator as of the dates presented (dollars in thousands).

Loan participations and whole loans sold to and serviced for others are not included in the accompanying consolidated balance sheets. The balance of loans serviced for others was $96.8 million and $135.4 million as of September 30, 2019 and December 31, 2018 , respectively. The unpaid principal balance of these loans was approximately $189.7 million and $187.6 million as of September 30, 2019 and December 31, 2018 , respectively. In the ordinary course of business, the Company makes loans to related parties including its executive officers, principal stockholders, directors and their immediate family members, as well as companies in which these individuals are principal owners. Loans outstanding to such related party borrowers amounted to approximately $95.8 million and $93.0 million as of September 30, 2019 and December 31, 2018 , respectively. The table below shows the aggregate principal balance of loans to such related parties as of the dates presented (dollars in thousands).

Determination of impairment is treated the same across all classes of loans. When the Company identifies a loan as impaired, it measures the impairment based on the present value of expected future cash flows, discounted at the loan’s effective interest rate, except when the sole (remaining) source of repayment for the loans is the operation or liquidation of the collateral. In these cases when foreclosure is probable, the Company uses the current fair value of the collateral, less selling costs, instead of discounted cash flows. If the Company determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs, and unamortized premium or discount), the Company recognizes impairment through an allowance estimate or a charge-off to the allowance. When the ultimate collectability of the total principal of an impaired loan is in doubt and the loan is on nonaccrual, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan is not in doubt and the loan is on nonaccrual, contractual interest is credited to interest income when received, under the cash basis method.

The Company strives to identify borrowers in financial difficulty early and work with them to modify their loans to more affordable terms before such loans reach nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases in which the Company grants the borrower new terms that provide for a reduction of either interest or principal, or otherwise include a concession, the Company identifies the loan as a TDR and measures any impairment on the restructuring as previously noted for impaired loans. Loans classified as TDRs, consisting of 19 credits, totaled $1.6 million at September 30, 2019 , compared to 24 credits totaling $2.2 million at December 31, 2018 . At September 30, 2019 , 11 of the restructured loans were considered TDRs due to modification of terms through adjustments to maturity, seven of the restructured loans were considered TDRs due to a reduction in the interest rate to a rate lower than the current market rate, and one restructured loan was considered a TDR due to forgiveness of interest due on the loan. As of September 30, 2019 , two of the TDRs, consisting of one $0.3 million construction and development loan and one $0.2 million 1-4 family loan, were in default of their modified terms and are included in nonaccrual loans. At December 31, 2018 , three of the TDRs, consisting of one $0.5 million commercial real estate loan, one $0.3 million construction and development loan, and one $0.2 million 1-4 family loan, were in default of their modified terms and are included in nonaccrual loans. The Company individually evaluates each TDR for allowance purposes, primarily based on collateral value, and excludes these loans from the loan population that is collectively evaluated for impairment. At September 30, 2019 and December 31, 2018 , there were no available balances on loans classified as TDRs that the Company was committed to lend. The table below presents the TDR pre- and post-modification outstanding recorded investments by loan categories for loans modified during the nine month periods ended September 30, 2019 and 2018 (dollars in thousands).

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Equity Incentive Plan. The Company’s 2017 Long-Term Incentive Compensation Plan (the “Plan”) authorizes the grant of various types of equity grants and awards, such as restricted stock, restricted stock units, stock options and stock appreciation rights, to eligible participants, which include all of the Company’s employees, non-employee directors, and consultants. The Plan has reserved 600,000 shares of common stock for grant, award or issuance to eligible participants, including shares underlying granted options. As of September 30, 2019 , 398,611 shares were available for future grants under the Plan. Shares covered by awards that expire or terminate will again be available for the grant of awards under the Plan. Stock Options The Company uses a Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes option pricing model incorporates various highly subjective assumptions, including expected term and expected volatility. The assumptions presented below were used for the options granted during the nine months ended September 30, 2019 . Expected dividends 0.82 % Expected volatility 27.26 % Risk-free interest rate 2.63 % Expected term (in years) 6.5 Weighted-average grant date fair value $ 7.30 Stock option expense in the accompanying consolidated statements of income for the three and nine months ended September 30, 2019 was $83,000 and $0.2 million , respectively, and $69,000 and $0.2 million for the three and nine months ended September 30, 2018 , respectively. At September 30, 2019 , there was $0.6 million of unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 3.05 years . The table below summarizes stock option activity for the periods presented. Nine months ended September 30, 2019 2018 Number of Options Weighted Average Exercise Price Number of Options Weighted Average Exercise Price Outstanding at beginning of period 340,646 $ 15.98 322,917 $ 15.09 Granted 36,984 24.40 31,788 24.30 Forfeited — — (1,333 ) 14.00 Exercised (12,082 ) 14.10 (12,415 ) 14.07 Outstanding at end of period 365,548 $ 16.90 340,957 $ 15.99 Exercisable at end of period 217,944 $ 15.14 99,917 $ 15.17 At September 30, 2019 , the shares underlying outstanding stock options and exercisable stock options had aggregate intrinsic values of $2.5 million and $1.9 million , respectively. Restricted Stock and Restricted Stock Units Under the Plan, the Company may grant restricted stock, restricted stock units, and other stock-based awards to Plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, restricted stock participants may exercise full voting rights and will receive all dividends paid with respect to the restricted shares. Restricted stock units do not have voting rights and do not receive dividends or dividend equivalents. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense for restricted stock is recognized over the requisite service period of generally five years for employees and two years for non-employee directors for the entire award on a straight-line basis. Upon vesting of restricted stock and restricted stock units, the benefit of tax deductions in excess of recognized compensation expense is reflected as an income tax benefit in the unaudited Consolidated Statements of Income. Historically, the Company has issued restricted stock awards to Plan participants. Beginning in 2019, the Company issued time vested restricted stock units to its non-employee directors and certain officers of the Company with vesting terms ranging from two years to five years . The total share-based compensation expense to be recognized for these awards is determined based on the market price of the Company’s common stock at the grant date applied to the total number of units awarded and is amortized over the vesting period. Stock compensation expense related to time vested restricted stock and restricted stock units in the accompanying consolidated statements of income was $0.3 million and $0.8 million for the three and nine months ended September 30, 2019 , respectively, and $0.2 million and $0.6 million for the three and nine months ended September 30, 2018 , respectively. At September 30, 2019 , there was $3.0 million of unrecognized compensation cost related to time vested restricted stock and restricted stock units that is expected to be recognized over a weighted average period of 3.45 years . The restricted stock and restricted stock unit activity is shown below for the periods presented.

DERIVATIVE FINANCIAL INSTRUMENT

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS As part of its liability management, the Company utilizes pay-fixed interest rate swaps to manage exposure against the variability in the expected future cash flows (future interest payments) attributable to changes in the 1-month LIBOR associated with the forecasted issuances of 1-month fixed rate debt arising from a rollover strategy. The maximum length of time over which the Company is currently hedging its exposure to the variability in future cash flows for forecasted transactions is approximately 4.9 years . As of September 30, 2019 , the Company had one interest rate swap agreement for a total notional amount of $50.0 million designated as a cash flow hedge. The interest rate swap was determined to be fully effective during the periods presented, and therefore no amount of ineffectiveness has been included in net income. The derivative contract is between the Company and a single counterparty. To mitigate credit risk, securities are pledged to the Company by the counterparty in an amount greater than or equal to the gain position of the derivative contracts. For the three and nine months ended September 30, 2019 , a gain of $0.1 million and a loss of $0.3 million , respectively, have been recognized in “Other comprehensive income (loss)” in the accompanying consolidated statements of comprehensive income for the change in fair value of the interest rate swaps compared to a loss of $11,000 and a gain of $0.3 million recognized for the three and nine months ended September 30, 2018 , respectively. The swap contract had a fair value of $0.2 million at September 30, 2019 and has been recorded in “Other assets” in the accompanying consolidated balance sheet. The accumulated gain of $0.2 million included in “Accumulated other comprehensive income (loss)” in the accompanying consolidated balance sheet would be reclassified to current earnings if the hedge transactions become probable of not occurring. The Company expects the hedges to remain fully effective during the remaining term of the swap contract. Customer Derivatives – Interest Rate Swaps In the third quarter of 2019, the Company began entering into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to an interest rate swap agreement, which serves to effectively swap the customer’s variable-rate loan into a fixed-rate loan. The Company then enters into a corresponding swap agreement with a third party in order to economically hedge its exposure through the customer agreement. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging, and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820, Fair Value Measurements. The Company did not recognize any gains or losses in other income resulting from fair value adjustments during the quarter ended September 30, 2019.

FAIR VALUES OF FINANCIAL INSTRU

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS In accordance with FASB ASC Topic 820, Fair Value Measurement and Disclosure (“ASC 820”), disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, is required. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Fair value is best determined based upon quoted market prices, or exit prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows, and the fair value estimates may not be realized in an immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. Fair Value Hierarchy In accordance with ASC 820, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 – Valuation is based upon quoted prices for identical assets or liabilities traded in active markets. Level 2 – Valuation is based upon observable inputs other than quoted prices included in level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 – Valuation is based upon unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following methods and assumptions were used by the Company in estimating fair value disclosures for financial instruments: Cash and Due from Banks – For these short-term instruments, fair value is the carrying value. Cash and due from banks is classified in level 1 of the fair value hierarchy. Federal Funds Sold – The fair value is the carrying value. The Company classifies these assets in level 1 of the fair value hierarchy. Investment Securities and Equity Securities – Where quoted prices are available in an active market, the Company classifies the securities within level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include exchange-traded equity securities. If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, and credit spreads. Examples of such instruments, which would generally be classified within level 2 of the valuation hierarchy if observable inputs are available, include obligations of U.S. government agencies and corporations, obligations of state and political subdivisions, corporate bonds, residential mortgage-backed securities, commercial mortgage-backed securities, and other equity securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in level 3. At September 30, 2019 and 2018, the majority of our level 3 investments was obligations of state and political subdivisions. The Company estimated the fair value of these level 3 investments using an option-adjusted discounted cash flow model which is based on readily traded comparable municipal credits and current spreads to the yield curves, adjusted for illiquidity of the local municipal market and sinking funds, if applicable. Loans – The fair value of portfolio loans, net is determined using an exit price methodology. The exit price methodology continues to be based on a discounted cash flow analysis, in which projected cash flows are based on contractual cash flows adjusted for prepayments for certain loan types (e.g. residential mortgage loans and multifamily loans) and the use of a discount rate based on expected relative risk of the cash flows. The discount rate selected considers loan type, maturity date, a liquidity premium, cost to service, and cost of capital, which is a level 3 fair value estimate. Deposit Liabilities – The fair values disclosed for noninterest-bearing demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). These noninterest-bearing deposits are classified in level 2 of the fair value hierarchy. All interest-bearing deposits are classified in level 3 of the fair value hierarchy. The carrying amounts of variable-rate (for example interest-bearing checking, savings, and money market accounts), fixed-term money market accounts, and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates on comparable instruments to a schedule of aggregated expected monthly maturities on time deposits. Short-Term Borrowings – The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings approximate their fair values. The Company classifies these borrowings in level 2 of the fair value hierarchy. Long-Term Borrowings, including Junior Subordinated Debt Securities – The fair values of long-term borrowings are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. The fair value of the Company’s long-term debt is therefore classified in level 3 in the fair value hierarchy. Subordinated Debt Securities – The fair value of subordinated debt is estimated based on current market rates on similar debt in the market. The Company classifies this debt in level 2 of the fair value hierarchy. Derivative Financial Instruments – The fair value for interest rate swap agreements is based upon the amounts required to settle the contracts. These derivative instruments are classified in level 2 of the fair value hierarchy. Fair Value of Assets and Liabilities Measured on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis are summarized in the table below as of the dates indicated (dollars in thousands).

Three months ended September 30, Nine months ended September 30, 2019 2018 2019 2018 Income tax expense $ 1,107 $ 516 $ 3,275 $ 2,823 Effective tax rate 19.2 % 11.3 % 19.5 % 21.6 % For the three and nine months ended September 30, 2019 , the effective tax rate differs from the statutory tax rate of 21%, effective January 1, 2018, due to tax exempt interest income earned on certain investment securities. The Company’s income tax expense for the three months ended September 30, 2018 includes a discrete tax benefit of $0.3 million related to the return-to-provision adjustments, resulting in a decrease in the effective tax rate for the period. In addition, income tax expense for the nine months ended September 30, 2018 includes a $0.6 million charge directly related to the revaluation of its deferred tax assets and liabilities as a result of the Tax Act, which is the primary reason the effective tax rate is greater than the statutory rate of 21% .

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Unfunded Commitments The Company is a party to financial instruments with off-balance-sheet risk entered into in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit consisting of loan commitments and standby letters of credit, which are not included in the accompanying financial statements. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The reserve for unfunded loan commitments is included in other liabilities in the consolidated balance sheets and was $102,000 and $66,000 at September 30, 2019 and December 31, 2018 , respectively. Commitments to extend credit are agreements to lend money with fixed expiration dates or termination clauses. The Company applies the same credit standards used in the lending process when extending these commitments, and periodically reassesses the customer’s creditworthiness through ongoing credit reviews. Since some commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Collateral is obtained based on the Company’s assessment of the transaction. Essentially all standby letters of credit issued have expiration dates within one year. The table below shows the approximate amounts of the Company’s commitments to extend credit as of the dates presented (dollars in thousands). September 30, 2019 December 31, 2018 Commitments to extend credit Loan commitments $ 193,804 $ 263,002 Standby letters of credit 13,883 11,114 Additionally, at September 30, 2019 , the Company had unfunded commitments of $38,000 for its investment in Small Business Investment Company qualified funds.

Leases [Abstract]
LEASES	LEASES On January 1, 2019, the Company adopted ASU 2016-02, Leases, as further explained in Note 1, Summary of Significant Accounting Policies. The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch operations. Prior to the Mainland acquisition on March 1, 2019, the Company leased only one of its properties, a future branch location expected to be opened in 2020. With the Mainland acquisition, the Company increased its branch network by three branches, of which two are operated under lease agreements. In addition, the Company entered into a lease agreement in the third quarter of 2019 for its second location in the Lafayette, Louisiana market, which opened on October 28, 2019. The Company’s branch locations operated under lease agreements have all been designated as operating leases. The Company does not lease equipment under operating leases, nor does it have leases designated as finance leases. The Company determines if an arrangement is a lease at inception. Operating leases, with the exception of short-term leases, are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in Bank premises and equipment, net and Accrued taxes and other liabilities, respectively, in the consolidated balance sheets. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The operating lease ROU asset also includes any lease pre-payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease. When it is reasonably certain that the Company will exercise an option to extend a lease, the extension is included in the lease term when calculating the present value of lease payments. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately, as the non-lease component amounts are readily determinable. No operating lease expense was recorded in the three and nine months ended September 30, 2018 as the Company had no operating leases until December 31, 2018. Quantitative information regarding the Company’s operating leases is presented below as of and for the nine months ended September 30, 2019 (dollars in thousands). Total operating lease cost $ 229.0 Weighted-average remaining lease term (in years) 10.7 Weighted-average discount rate 3.1 % As of September 30, 2019 , the Company’s lease ROU assets and related lease liabilities were each $3.4 million , and have remaining terms ranging from 4 to 12 years , including extension options if the Company is reasonably certain they will be exercised. Future minimum lease payments due under non-cancelable operating leases at September 30, 2019 are presented below (dollars in thousands). 2019 $ 90 2020 398 2021 403 2022 408 2023 405 Thereafter 2,352 Total $ 4,056 At September 30, 2019 , the Company had not entered into any material leases that have not yet commenced.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On August 20, 2019, the Company announced that the Bank entered into a Purchase and Assumption Agreement (“Agreement”), pursuant to which the Bank will acquire certain assets, deposits and other liabilities relating to two existing branch locations of Dallas, Texas-based PlainsCapital Bank (“PlainsCapital”), a wholly-owned subsidiary of Hilltop Holdings Inc. The branches are located in the Texas cities of Victoria and Alice. Under the terms of the Agreement, the Bank expects to acquire approximately $42 million in deposits and approximately $52 million in loans. In addition, the Bank will acquire substantially all the fixed assets at the branch locations and will assume the leases for the branch facilities. The transaction is expected to close in the first quarter of 2020, subject to regulatory approvals and other customary closing conditions. On November 1, 2019, the Company and the Bank completed the previously announced acquisition of Bank of York in York, Alabama (“Bank of York”). The acquisition was completed pursuant to the terms of the Agreement and Plan of Reorganization (the “Merger Agreement”), dated July 30, 2019, by and among the Company, the Bank and Bank of York. Under the terms of the Merger Agreement, all of the issued and outstanding shares of Bank of York common stock were converted into aggregate merger consideration of $15.0 million . At November 1, 2019, Bank of York had approximately $101 million in assets, $46 million in loans, $85 million in deposits and $11 million in stockholders’ equity. Bank of York offers a full range of banking products and services to the residents of Sumter and Tuscaloosa Counties through its two branch locations in York and Livingston, Alabama and a loan production office in Tuscaloosa, Alabama.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of Investar Holding Corporation (the “Company”) have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include information or footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with GAAP. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the three and nine month periods ended September 30, 2019 is not necessarily indicative of the results that may be expected for the entire fiscal year. These statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2018 , including the notes thereto, which were included as part of the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on March 15, 2019.
Nature of Operations	Nature of Operations Investar Holding Corporation, headquartered in Baton Rouge, Louisiana, provides full banking services, excluding trust services, through its wholly-owned banking subsidiary, Investar Bank, National Association (the “Bank”), a national bank. The Company’s primary markets are south Louisiana, southeast Texas and, as of November 1, 2019, southwest Alabama. At September 30, 2019 , the Company operated 22 full service branches located in Louisiana and 3 full service branches located in Texas, and had 285 employees. On November 1, 2019, the Company completed its acquisition of Bank of York in York, Alabama and added 2 additional branch locations in York and Livingston, Alabama, as well as a loan production office in Tuscaloosa, Alabama.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the allowance for loan losses may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated. Other estimates that are susceptible to significant change in the near term relate to the determination of other-than-temporary impairments of securities and the fair value of financial instruments.
Investment Securities	Investment Securities The Company’s investments in securities are accounted for in accordance with applicable guidance contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), which requires the classification of securities into one of the following categories: • Securities to be held to maturity (“HTM”): bonds, notes, and debentures for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. • Securities available for sale (“AFS”): available for sale securities consist of bonds, notes, and debentures that are available to meet the Company’s operating needs. These securities are reported at fair value. Unrealized holding gains and losses, net of tax, on AFS debt securities are reported as a net amount in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Realized gains and losses on the sale of debt securities are determined using the specific-identification method. The Company follows FASB guidance related to the recognition and presentation of other-than-temporary impairment. The guidance specifies that if an entity does not have the intent to sell a debt security and it is not more likely than not that the Company will be required to sell the security prior to recovery, the security would not be considered other-than-temporarily impaired unless there is a credit loss. When an entity does not intend to sell the security, and it is more likely than not that the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income.
Equity Securities	Equity Securities The Company is a member of the Federal Home Loan Bank (“FHLB”) system. Members of the FHLB are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, is restricted as to redemption, and is periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Equity securities also include investments in our other correspondent banks including Independent Bankers Financial Corporation (“IBFC”) and First National Bankers Bank (“FNBB”) stock.
Loans	Loans The Company’s loan portfolio categories include real estate, commercial and consumer loans. Real estate loans are further categorized into construction and development, 1-4 family residential, multifamily, farmland and commercial real estate loans. The consumer loan category includes loans originated through indirect lending. Indirect lending, which is lending initiated through third-party business partners, is largely comprised of loans made through automotive dealerships. Loans for which management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off are stated at unpaid principal balances, adjusted by an allowance for loan losses. Interest on loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. Loans are ordinarily placed on nonaccrual when a loan is specifically determined to be impaired or when principal or interest is delinquent for 90 days or more; however, management may elect to continue the accrual when the estimated net realizable value of collateral is sufficient to cover the principal balance and the accrued interest. Any unpaid interest previously accrued on nonaccrual loans is reversed from income. Interest income, generally, is not recognized on specific impaired loans unless the likelihood of further loss is remote. Interest payments received on such loans are applied as a reduction of the loan principal balance. Interest income on other nonaccrual loans is recognized only to the extent of interest payments received. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period of repayment performance by the borrower. The Company considers a loan to be impaired when, based upon current information and events, it believes it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Company’s impaired loans include troubled debt restructurings and performing and non-performing loans for which full payment of principal or interest is not expected. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. The Company calculates an allowance required for impaired loans based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of its collateral. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance is required as a component of the allowance for loan losses. Changes to the valuation allowance are recorded as a component of the provision for loan losses. The Company follows the FASB accounting guidance on sales of financial assets, which includes participating interests in loans. For loan participations that are structured in accordance with this guidance, the sold portions are recorded as a reduction of the loan portfolio. Loan participations that do not meet the criteria are accounted for as secured borrowings.
Allowance for Loan Losses	Allowance for Loan Losses The adequacy of the allowance for loan losses is determined in accordance with GAAP. The allowance for loan losses is estimated through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the loan balance is uncollectable. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount that management believes will be adequate to absorb probable losses inherent in the loan portfolio as of the balance sheet date based on evaluations of the collectability of loans and prior loan loss experience. The evaluations take into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, review of specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. Allowances for impaired loans are generally determined based on collateral values or the present value of estimated cash flows. Credits deemed uncollectible are charged to the allowance. Provisions for loan losses and recoveries on loans previously charged off are added to the allowance. Past due status is determined based on contractual terms. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience adjusted for qualitative factors. Based on management’s review and observations made through qualitative review, management may apply qualitative adjustments to determine loss estimates at a group and/or portfolio segment level as deemed appropriate. Management has an established methodology to determine the adequacy of the allowance for loan losses that assesses the risks and losses inherent in its portfolio and portfolio segments. The Company utilizes an internally developed model that requires judgment to determine the estimation method that fits the credit risk characteristics of the loans in its portfolio and portfolio segments. Qualitative and environmental factors that may not be directly reflected in quantitative estimates include: asset quality trends, changes in loan concentrations, new products and process changes, changes and pressures from competition, changes in lending policies and underwriting practices, trends in the nature and volume of the loan portfolio, changes in experience and depth of lending staff and management and national and regional economic trends. Changes in these factors are considered in determining changes in the allowance for loan losses. The impact of these factors on the Company’s qualitative assessment of the allowance for loan losses can change from period to period based on management’s assessment of the extent to which these factors are already reflected in historic loss rates. The uncertainty inherent in the estimation process is also considered in evaluating the allowance for loan losses. In the ordinary course of business, the Bank enters into commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. The reserve for unfunded lending commitments is included in accrued taxes and other liabilities in the consolidated balance sheet.
Acquisition Accounting	Acquisition Accounting Acquisitions are accounted for under the purchase method of accounting. Purchased assets and assumed liabilities are recorded at their respective acquisition date fair values, and identifiable intangible assets are recorded at fair value. If the consideration given exceeds the fair value of the net assets received, goodwill is recognized. If the fair value of the net assets received exceeds the consideration given, a bargain purchase gain is recognized. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Purchased loans acquired in a business combination are recorded at their estimated fair value as of the acquisition date. The fair value of loans acquired is determined using a discounted cash flow model based on assumptions regarding the amount and timing of principal and interest prepayments, estimated payments, estimated default rates, estimated loss severity in the event of defaults, and current market rates. Estimated credit losses are included in the determination of fair value; therefore, an allowance for loan losses is not recorded on the acquisition date. The fair value adjustment is amortized over the life of the loan using the effective interest method, except for those loans accounted for under ASC Topic 310-30, discussed below. The Company accounts for acquired impaired loans under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). An acquired loan is considered impaired when there is evidence of credit deterioration since origination and it is probable, at the date of acquisition, that we will be unable to collect all contractually required payments. ASC 310-30 prohibits the carryover of an allowance for loan losses for acquired impaired loans. Over the life of the acquired loans, we continually estimate the cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics. As of the end of each fiscal quarter, we evaluate the present value of the acquired loans using the effective interest rates. For any increases in cash flows expected to be collected, we adjust the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life, while we recognize a provision for loan loss in the consolidated statement of operations if the cash flows expected to be collected have decreased.
Servicing Rights	Servicing Rights Primary servicing rights represent the Company’s right to service consumer automobile loans for third-party whole-loan sales and loans sold as participations. Primary servicing involves the collection of payments from individual borrowers and the distribution of these payments to the investors. The Company capitalizes the value expected to be realized from performing specified automobile servicing activities for others as automobile servicing rights (“ASRs”) when the expected future cash flows from servicing are projected to be more than adequate compensation for such activities. These capitalized servicing rights are purchased or retained upon sale of consumer automobile loans. The Company measures all consumer automobile servicing assets and liabilities at fair value. The Company defines servicing rights based on both the availability of market inputs and the manner in which the Company manages the risks of servicing assets and liabilities. The Company leverages all available relevant market data to determine the fair value of recognized servicing assets and liabilities. The Company calculates the fair value of ASRs using various assumptions including future cash flows, market discount rates, expected prepayments, servicing costs and other factors. A significant change in prepayments of loans in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of ASRs.
Reclassifications	Reclassifications Certain reclassifications have been made to the 2018 financial statements to be consistent with the 2019 presentation, if applicable.
Concentrations of Credit Risk	Concentrations of Credit Risk The Company’s loan portfolio consists of the various types of loans described in Note 5. Loans and Allowance for Loan Losses. Real estate or other assets secure most loans. The majority of loans have been made to individuals and businesses in the Company’s market of southeast Louisiana. Customers are dependent on the condition of the local economy for their livelihoods and servicing their loan obligations. The Company does not have any significant concentrations in any one industry or individual customer.
Tax Cuts and Jobs Act	Tax Cuts and Jobs Act Public law No. 115-97, known as the Tax Cuts and Jobs Act (the “Tax Act”), enacted on December 22, 2017, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. Also on December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for tax effects of the Tax Act. SAB 118 provided a measurement period of up to one year from the enactment date to complete the accounting. Any adjustments during the measurement period were included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments were determined.
Accounting Standards Adopted in 2019 and Recent Accounting Pronouncements	Accounting Standards Adopted in 2019 In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718) , which expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services and supersedes Subtopic 505-50, “Equity – Equity-Based Payments to Non-Employees.” The Company adopted ASU 2018-07 on January 1, 2019. The adoption of ASU 2018-07 did not have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , which amends the hedge accounting model in Topic 815 to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. The amendments expand an entity’s ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This amended guidance was adopted on January 1, 2019, and, given the current level of derivatives designated as hedges, did not have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities . The amendments in the ASU shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company adopted ASU 2017-08 on January 1, 2019. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . The ASU intends to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities and disclosing key information about leasing arrangements. The ASU requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers . The new lease guidance simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) may apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may also elect to apply the amendments in the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company historically has owned all property and equipment, although it entered an operating lease for a future branch location on December 31, 2018. The Company adopted the ASU on January 1, 2019, using the modified retrospective approach, and recognized a right-of-use asset and related lease liability of $1.2 million . At September 30, 2019 , the right-of-use asset and related lease liability were each $3.4 million . The adoption of this ASU did not have a significant impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements FASB ASC Topic 350 “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” Update No. 2018-15. In August 2018, the FASB issued ASU 2018-15. This ASU requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for the Company on January 1, 2020. Early adoption is permitted, including adoption in any interim period. The adoption of ASU 2018-15 is not expected to have a material impact on the Company’s consolidated financial statements. FASB ASC Topic 820 “Fair Value Measurement: Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” Update No. 2018-13. In August 2018, the FASB issued ASU 2018-13, which modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. ASU 2018-13 removes the disclosure requirement detailing the amount of and reasons for transfers between Level 1 and Level 2 and the valuation processes for Level 3 fair value measurements will be removed. In addition, this ASU modifies the disclosure requirement for investments in certain entities that calculate net asset value. Lastly, ASU 2018-13 adds a disclosure requirement for changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 measurements. ASU 2018-13 is effective for the Company on January 1, 2020. Early adoption is permitted upon the issuance of ASU 2018-13. The removed and modified disclosures will be adopted on a retrospective basis, and the new disclosures will be adopted on a prospective basis. The adoption of ASU 2018-13 is not expected to have a material impact on the Company’s consolidated financial statements. FASB ASC Topic 350 “Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment” Update No. 2017-04. The FASB issued ASU No. 2017-04 in January 2017. The ASU simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Therefore, any carrying amount which exceeds the reporting unit’s fair value, up to the amount of goodwill recorded, will be recognized as an impairment loss. ASU 2017-04 will be effective for the Company on January 1, 2020. The amendment will be applied prospectively on or after the effective date. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. Based on recent goodwill impairments tests, which did not require the application of Step 2, the Company does not expect the adoption of this ASU to have an immediate impact. FASB ASC Topic 326 “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments” Update No. 2016-13. The FASB issued ASU No. 2016-13 in June 2016. The ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. We are currently evaluating the potential impact of ASU 2016-13 on our financial statements. In that regard, we have formed a cross-functional working group, under the direction of our Chief Financial Officer and our Chief Risk Officer. The working group is comprised of individuals from various functional areas including credit, risk management, finance and information technology. We have developed an implementation plan to include assessment of processes, portfolio segmentation, model development, system requirements and the identification of data and resource needs, among other things. We have also selected a third-party vendor solution to assist us in the application of ASU 2016-13. The adoption of ASU 2016-13 is likely to result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses on debt securities. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios, as well as the prevailing economic conditions and forecasts, as of the adoption date. This amendment was originally effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. In July 2019, the FASB proposed changes that would delay the effective date for smaller reporting companies, as defined by the SEC, and other non-SEC reporting entities. In October 2019, the FASB voted in favor of finalizing its proposal to delay the effective date of this standard to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. ASU 2016-13 will be effective for the Company on January 1, 2023. The Company expects to adopt the standard as soon as practicable, based upon progress on the implementation plan. Adoption prior to the revised effective date of January 1, 2023 is permitted by the ASU.

Cumulative Effect of New Accounting Principle in Period of Adoption	us-gaap_CumulativeEffectOfNewAccountingPrincipleInPeriodOfAdoption	$ (5,000)
[1]	Represents the impact of adopting Accounting Standards Update (“ASU”) No. 2016-01, Financial Instruments - Overall (Topic 825), which requires equity investments, other than equity method investments, to be measured at fair value with changes in fair value recognized in net income. Upon adoption on January 1, 2018, the ASU required a cumulative-effect adjustment to retained earnings to reclassify the cumulative change in the fair value of equity securities previously recognized in accumulated other comprehensive income.
