SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended

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, 2017 are 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, 2016 , 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 on March 9, 2017. 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 (the “Bank”), a Louisiana-chartered bank. The Company’s primary market is South Louisiana. At September 30, 2017 , the Company operated 15 full service banking offices located throughout its market and had 227 employees. 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 statements in conformity with U.S. 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 available for sale 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 investment 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 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. 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. 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 homogenous 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. 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. Reclassifications Certain reclassifications have been made to the 2016 financial statements to be consistent with the 2017 presentation. Concentrations of Credit Risk The Company’s loan portfolio consists of the various types of loans described in Note 5, Loans. 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 South 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. New Accounting Pronouncement Accounting Standards Update (“ASU”) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting was effective for the Company on January 1, 2017. ASU 2016-09 requires that all income tax effects related to vestings of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense. Previously, excess income tax benefits of a vested award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied to vestings occurring on or after January 1, 2017 and resulted in recording a $83,000 tax benefit for the nine months ended September 30, 2017. ASU 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. We have elected to apply that change in cash flow classification on a prospective basis, and prior periods have not been adjusted. The impact of this change and that of the remaining provisions of ASU 2016-09 did not have a significant impact on our financial statements. Recent Accounting Pronouncements FASB ASC Topic 815 “Derivatives and Hedging” Update No. 2017-12. The Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-12 in August 2017. The ASU 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 is effective for the Company on January 1, 2019, and, given the current level of derivatives designated as hedges, is not expected to have a material impact on our consolidated operating results or financial condition. FASB ASC Topic 718 “Compensation – Stock Compensation: Scope of Modification Accounting” Update No. 2017-09. The FASB issued ASU No. 2017-09 in May 2017. The ASU clarifies when changes to terms or conditions of a share-based payment award must be accounted for as a modification. Under the new guidance, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the fair value of the award, (ii) the vesting conditions of the award, and (iii) the classification of the award as either an equity or liability instrument. ASU 2017-09 will be effective for the Company beginning January 1, 2018. Early adoption is permitted. The guidance requires companies to apply the requirements prospectively to awards modified on or after the adoption date. ASU 2017-09 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASC Subtopic 310-20 “Receivables – Nonrefundable Fees and Other Costs, Premium Amortization on Purchased Callable Debt Securities” Update No. 2017-08. The FASB issued ASU No. 2017-08 in March 2017. 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. Update 2017-08 will be effective for the Company beginning January 1, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact of ASU 2017-08 on its accounting and disclosures. 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 amendments 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 805 “Business Combinations: Clarifying the Definition of a Business” Update No. 2017-01. The FASB issued ASU No. 2017-01 in January 2017. The amendments in the ASU are intended to clarify the definition and the current interpretation of a business to assist companies and other reporting organizations with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The ASU will be effective for the Company beginning January 1, 2018. The amendments will be applied prospectively on or after the effective date. Early application of the amendments in this ASU is allowed for transactions, including when a subsidiary or group of assets is deconsolidated/derecognized, in which the acquisition date occurs before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. The adoption of this standard is not expected to have a material impact on the Company’s financial statements. FASB ASC Topic 230 “Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments” Update No. 2016-15. The FASB issued ASU No. 2016-15 in August 2016. The amendments in the ASU address eight specific cash flow issues with the objective of reducing the existing diversity in practice, as the issues are either unclear or do not have specific guidance under current GAAP. ASU 2016-15 will be effective on January 1, 2018. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. 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 amendments introduce an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. The ASU also amends the current AFS security impairment model for debt securities. The new model will require an estimate of expected credit losses when the fair value is below the amortized cost of the asset through the use of an allowance to record estimated credit losses (and subsequent recoveries). Non-credit related losses will continue to be recognized through other comprehensive income. In addition, the amendments provide for a simplified accounting model for purchased financial assets with a more-than-insignificant amount of credit deterioration since their origination. The initial estimate of expected credit losses would be recognized through an allowance for loan losses with an offset (i.e., increase) to the cost basis of the related financial asset at acquisition. ASU 2016-13 will be effective for the Company beginning January 1, 2020. The amendments will be applied through a modified-retrospective approach, resulting in a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. A prospective transition approach is required for debt securities for which other-than-temporary impairment had been recognized before the effective date. Amounts previously recognized in accumulated other comprehensive income as of the date of adoption that relate to improvements in cash flows expected to be collected should continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption should be recorded in earnings when received. Management is currently evaluating the potential impact of ASU 2016-13 on the Company’s consolidated financial statements. FASB ASC Topic 825 “Financial Instruments – Overall” Update No. 2016-1. The FASB issued ASU No. 2016-1 in January 2016 to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The ASU will not change the guidance for classifying and measuring investments in debt securities or loans; however, it will impact how entities measure certain equity investments, recognize changes in the fair value of financial liabilities measured under the fair value option that are attributable to instrument-specific credit risk, and disclose and present financial assets and liabilities in financial statements. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a new practicability exception, the equity method of accounting, or consolidation, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. The amendments will also require entities to present financial assets and financial liabilities separately, grouped by measurement category and form of financial asset in the statement of financial position or in the accompanying notes to the financial statements. Entities will also no longer have to disclose the methods and significant assumptions for financial instruments measured at amortized cost, but will be required to measure such instruments under the “exit price” notion for disclosure purposes. The amendments in this ASU are effective for the Company beginning January 1, 2018. The Company will record a cumulative-effect adjustment to beginning retained earnings as of the beginning of the first reporting period in which the guidance is adopted, with two exceptions. The amendments related to equity investments without readily determinable fair values will be effective prospectively. The requirement to use the exit price notion to measure fair value of financial instruments for disclosure purposes will also be applied prospectively. The Company does not expect a significant cumulative-effect adjustment to be recorded at adoption or any significant impact to the consolidated financial statements associated with the accounting for its current equity investments. The Company does anticipate financial statement disclosures to be impacted, specifically related to financial instruments measured at amortized cost whose fair values are disclosed under the “entry price” notion, but is currently still in the process of determining the impact. FASB ASC Topic 606 “Revenue from Contracts with Customers” Update No. 2014-9. The FASB issued ASU No. 2014-9 in May 2014 which implements a common revenue standard and clarifies the principles used for recognizing revenue. The amendments in the ASU clarify that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As part of that principle, the entity should identify the contract(s) with the customer, identify the performance obligation(s) of the contract, determine the transaction price, allocate that transaction price to the performance obligation(s), and then recognize revenue when or as the entity satisfies the performance obligation(s). The amendments also provide additional guidance/principles associated with gross vs. net presentation (i.e., principal versus agency considerations). The amendments in ASU No. 2014-9 will be effective for the Company beginning January 1, 2018. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The amendments will be applied through the election of one of two retrospective methods. The Company intends to adopt the amendments beginning January 1, 2018 through the modified-retrospective transition method and does not expect to recognize a significant cumulative adjustment to equity upon implementation of the standard. Further, the Company does not expect a significant impact to the Company’s consolidated statements of comprehensive income or consolidated balance sheets from either a presentation or timing perspective, but is still analyzing some contracts.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS On July 1, 2017, the Company completed the acquisition of Citizens Bancshares, Inc. (“Citizens”) and its wholly-owned subsidiary, Citizens Bank, located in Evangeline Parish, Louisiana. The Company acquired 100% of Citizens’ outstanding common shares for an aggregate amount of cash consideration equal to $45.8 million , or approximately $419.20 per share. The acquisition of Citizens expands the Company’s branch footprint in Louisiana and increases the core deposit base to help position the Company to continue to grow. On the date of acquisition, Citizens had approximately $250 million in assets, $130 million in net loans, $212 million in deposits, and $36 million in stockholders’ equity, and served the residents of Evangeline Parish through its three branch locations. Acquisition related costs of $0.8 million and $1.0 million are included in acquisition expenses in the accompanying consolidated statements of income, for the three and nine month periods ended September 30, 2017 . These costs include system conversion and integrating operations charges as well as legal and consulting expenses. In connection with the acquisition, the Company recorded $8.7 million of goodwill. Goodwill resulted from a combination of synergies and cost savings, expansion in Louisiana with the addition of three branch locations, enhanced products and services and a lower cost of funds. The Company also recorded a core deposit intangible of $1.5 million . The change in goodwill and other intangibles at September 30, 2017 compared to December 31, 2016 is primarily attributable to the goodwilll and core deposit intangible recorded as a result of the Citizens acquisition. The table below shows the allocation of the consideration paid for Citizens’ 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, are subject to refinement for up to one year after the closing date of the acquisition as additional information becomes available. Purchase price: Cash paid $ 45,800 Fair value of assets acquired: Cash and cash equivalents 44,565 Investment securities 69,897 Loans 129,189 Bank premises and equipment 3,337 Other intangible assets 1,462 Other assets 2,558 Total assets acquired 251,008 Fair value of liabilities acquired: Deposits 212,228 Other liabilities 1,652 Total liabilities assumed 213,880 Fair value of net assets acquired 37,128 Goodwill $ 8,672 Fair value adjustments to assets acquired and liabilities assumed are generally amortized using either an effective yield or straight-line basis 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. The tables below present information about the loans acquired from Citizens as of the date of acquisition (dollars in thousands).

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, 2016 and should not be considered representative of future operating results. The pro forma net income for the three and nine month periods ended September 30, 2017 excludes the tax-affected amounts of $0.8 million and $2.0 million , respectively, of acquisition expenses recorded in noninterest expense by both the Company and Citizens.

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. Due to the nature of the investment and current market prices, these unrealized losses are considered a temporary impairment of the securities.

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.

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 $204.6 million and $274.9 million as of September 30, 2017 and December 31, 2016 , respectively. The unpaid principal balance of these loans was approximately $258.3 million and $319.6 million as of September 30, 2017 and December 31, 2016 , respectively. For the three and nine months ended September 30, 2017 , the Company recognized $0.4 million and $1.2 million , respectively, of servicing fees and other fees collected on serviced loans. In the ordinary course of business, the Company makes loans to its executive officers, principal stockholders, directors and to companies in which these individuals are principal owners. Loans outstanding to such related party borrowers (including companies in which they are principal owners) amounted to approximately $26.1 million and $20.0 million as of September 30, 2017 and December 31, 2016 , respectively. These loans are all current and performing according to the original terms. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company or the Bank and did not involve more than normal risk of collectability or present other unfavorable features.

Generally, those loans rated special mention or lower are evaluated for impairment each quarter. 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 for loan losses. 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 following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, as of the dates indicated (dollars in thousands).

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 eighteen credits, totaled approximately $1.6 million at September 30, 2017 , compared to eighteen credits totaling $2.4 million at December 31, 2016 . Eight of the restructured loans were considered TDRs due to modification of terms through adjustments to maturity, nine 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 modification of terms through principal payment forbearance, paying interest only for a specified period of time. As of September 30, 2017 and December 31, 2016 , all restructured loans were performing under their modified terms. 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, 2017 and December 31, 2016 , 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, 2017 and 2016 (dollars in thousands).

STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Equity Incentive Plan. The Company previously granted equity awards to its employees and non-employee directors under its 2014 Long-Term Incentive Compensation Plan (the “2014 Plan”). Effective May 24, 2017, the Company’s shareholders approved its 2017 Long-Term Incentive Compensation Plan (the “Plan”) and ceased using the 2014 Plan. The Plan authorizes the grant of various types of equity grants and awards, such as restricted stock, 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. The Plan is administered by the Compensation Committee of the Company’s Board of Directors, which determines, within the provisions of the Plan, those eligible employees to whom, and the times at which, grants and awards will be made. The Compensation Committee, in its discretion, may delegate its authority and duties under the Plan to specified officers; however, only the Compensation Committee may approve the terms of grants and awards to the Company’s executive officers and directors. 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. Stock option expense in the accompanying consolidated statements of income for the three and nine months ended September 30, 2017 was $57,000 and $0.2 million , respectively, and $48,000 and $0.1 million for the three and nine months ended September 30, 2016 , respectively. The assumptions presented below were used for the options granted during the nine months ended September 30, 2017 . Expected dividends 0.22 % Expected volatility 20.46 % Risk-free interest rate 2.19 % Expected term (in years) 7.0 Weighted-average grant date fair value $ 5.39 At September 30, 2017 , there was $0.7 million of unrecognized compensation cost related to stock options that is expected to be recognized over a weighted-average period of 2.98 years .

Time Vested Restricted Stock Awards During the nine months ended September 30, 2017 and 2016 , the Company issued shares of time vested restricted stock with vesting terms ranging from 2 to 5 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 shares awarded and is amortized over the vesting period. The table below summarizes the time vested restricted stock award activity for the periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS The Company currently holds interest rate swap contracts 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. An interest rate swap is an agreement whereby one party agrees to pay a fixed rate of interest on a notional principal amount in exchange for receiving a floating rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged. 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 2.9 years . The total notional amount of the derivative contracts is $50.0 million . For the three and nine months ended September 30, 2017 , a gain of $37,000 and $0.1 million , respectively, have been recognized in “Other comprehensive income” in the accompanying consolidated statements of comprehensive income for the change in fair value of the interest rate swaps compared to a gain of $0.3 million and a loss of $0.4 million , respectively, recognized for the three and nine months ended September 30, 2016 . The swap contracts had a fair value of $0.2 million as of September 30, 2017 and have been recorded in “Other assets” in the accompanying consolidated balance sheet. The accumulated gain of $0.1 million included in “Accumulated other comprehensive 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 contracts.

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. 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 Other 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 highly liquid government bonds and exchange-traded equities. 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, include Government Sponsored Enterprise obligations, corporate bonds and other securities. Mortgage-backed securities are included in level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in level 3. Equity securities are valued based on market quoted prices and are classified in level 1 as they are actively traded. Loans – For variable-rate loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (for example, 1-4 family residential), credit card loans, and other consumer loans are based on quoted market prices of similar instruments sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. Fair values for other loans (for example, commercial real estate and investment property mortgage loans, commercial and industrial loans) are estimated using discounted cash flow analyses, using market interest rates for comparable loans. Fair values for nonperforming loans, which are loans for which the accrual of interest has stopped or loans that are contractually 90 past due on which interest continues to accrue, are estimated using discounted cash flow analyses or underlying collateral values, where applicable. The Company classifies loans in level 3 of the fair value hierarchy. 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. 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. All interest-bearing deposits are classified in level 3 of the fair value hierarchy. 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 – The fair values of long-term borrowings are estimated using discounted cash flows 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 Instruments – The fair value for interest rate swap agreements are 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).

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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. 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, 2017 December 31, 2016 Commitments to extend credit Loan commitments $ 176,517 $ 142,891 Standby letters of credit 703 1,008 Additionally, at September 30, 2017 , the Company had unfunded commitments of $0.3 million for its investment in Small Business Investment Company qualified funds. During the third quarter of 2017, the Company announced that it has entered into a definitive agreement (the “Agreement”) to acquire BOJ Bancshares, Inc. (“BOJ”) and its wholly-owned subsidiary, The Highlands Bank, in Jackson, Louisiana. The acquisition would add five branch locations in the Company’s existing Baton Rouge market. The transaction, which has been unanimously approved by each company’s board of directors, is expected to close in the fourth quarter of 2017 and is subject to customary closing conditions, including obtaining approval by BOJ’s shareholders. The BOJ special meeting of shareholders to vote upon the Agreement has been called for November 15, 2017. The Company has received regulatory approvals from the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, and the Louisiana Office of Financial Institutions. Under the terms of the Agreement, consideration will be paid to the shareholders of BOJ in the form of cash and shares of the Company’s common stock. Shareholders of BOJ will be entitled to receive an aggregate amount of cash consideration equal to $3.95 million , subject to certain adjustments. BOJ will also be entitled to receive an aggregate of 799,559 shares of Investar common stock, subject to adjustment. Assuming no adjustments to the merger consideration under the terms of the Agreement, the transaction is valued at approximately $22.78 million based upon the closing price of Investar’s common stock of $23.55 on October 17, 2017. It is expected that shareholders of BOJ will own approximately 8% of the combined company following the acquisition. With respect to potential adjustments to the merger consideration, the Agreement includes two collar mechanisms that could result in a modification to the number of shares of the Company’s common stock to be issued. Fewer shares would be issued if the average closing price of the Company’s common stock for the ten consecutive trading days prior to the closing date is greater than $26.11 , and more shares would be issued if such average closing price is less than $20.43 . As a result of these collar mechanisms, the implied value of the aggregate merger consideration will not fluctuate above $24.8 million or below $20.3 million due to changes in the market price of the Company’s common stock. The parties are not obligated to close the transaction if such average closing price is not greater than $19.50 . In addition, the aggregate merger consideration is subject to a dollar-for-dollar downward adjustment to the extent that BOJ’s adjusted tangible shareholders’ equity, as defined in the Agreement, is less than $16.5 million as of a date to be determined by BOJ that is within ten days prior to the closing of the merger. If this downward adjustment is triggered, both the aggregate cash consideration and aggregate stock consideration would be reduced pro rata. At September 30, 2017, BOJ had, on a consolidated basis, approximately $154 million in assets, $108 million in net loans, $126 million in deposits, and $17 million in stockholders’ equity. The Highlands Bank offers a full range of banking products and services to the residents of East Feliciana, West Feliciana, and East Baton Rouge Parishes through its main office and four branch locations.

SUMMARY OF SIGNIFICANT ACCOUN23

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2017
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, 2017 are 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, 2016 , 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 on March 9, 2017.
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 (the “Bank”), a Louisiana-chartered bank. The Company’s primary market is South Louisiana. At September 30, 2017 , the Company operated 15 full service banking offices located throughout its market and had 227 employees
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 statements in conformity with U.S. 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 available for sale 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 investment 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 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.
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
Reclassifications	Reclassifications Certain reclassifications have been made to the 2016 financial statements to be consistent with the 2017 presentation.
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. 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 South 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.
Recent Accounting Pronouncements	New Accounting Pronouncement Accounting Standards Update (“ASU”) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting was effective for the Company on January 1, 2017. ASU 2016-09 requires that all income tax effects related to vestings of share-based payment awards be reported in earnings as an increase (or decrease) to income tax expense. Previously, excess income tax benefits of a vested award were reported as an increase (or decrease) to additional paid-in capital to the extent that those benefits were greater than (or less than) the income tax benefits recognized in earnings during the award’s vesting period. The requirement to report those income tax effects in earnings has been applied to vestings occurring on or after January 1, 2017 and resulted in recording a $83,000 tax benefit for the nine months ended September 30, 2017. ASU 2016-09 also requires that all income tax-related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows. We have elected to apply that change in cash flow classification on a prospective basis, and prior periods have not been adjusted. The impact of this change and that of the remaining provisions of ASU 2016-09 did not have a significant impact on our financial statements. Recent Accounting Pronouncements FASB ASC Topic 815 “Derivatives and Hedging” Update No. 2017-12. The Financial Accounting Standards Board (“FASB”) issued ASU No. 2017-12 in August 2017. The ASU 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 is effective for the Company on January 1, 2019, and, given the current level of derivatives designated as hedges, is not expected to have a material impact on our consolidated operating results or financial condition. FASB ASC Topic 718 “Compensation – Stock Compensation: Scope of Modification Accounting” Update No. 2017-09. The FASB issued ASU No. 2017-09 in May 2017. The ASU clarifies when changes to terms or conditions of a share-based payment award must be accounted for as a modification. Under the new guidance, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the fair value of the award, (ii) the vesting conditions of the award, and (iii) the classification of the award as either an equity or liability instrument. ASU 2017-09 will be effective for the Company beginning January 1, 2018. Early adoption is permitted. The guidance requires companies to apply the requirements prospectively to awards modified on or after the adoption date. ASU 2017-09 is not expected to have a significant impact on the Company’s consolidated financial statements. FASB ASC Subtopic 310-20 “Receivables – Nonrefundable Fees and Other Costs, Premium Amortization on Purchased Callable Debt Securities” Update No. 2017-08. The FASB issued ASU No. 2017-08 in March 2017. 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. Update 2017-08 will be effective for the Company beginning January 1, 2019. Early adoption is permitted, including adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact of ASU 2017-08 on its accounting and disclosures. 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 amendments 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 805 “Business Combinations: Clarifying the Definition of a Business” Update No. 2017-01. The FASB issued ASU No. 2017-01 in January 2017. The amendments in the ASU are intended to clarify the definition and the current interpretation of a business to assist companies and other reporting organizations with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The ASU will be effective for the Company beginning January 1, 2018. The amendments will be applied prospectively on or after the effective date. Early application of the amendments in this ASU is allowed for transactions, including when a subsidiary or group of assets is deconsolidated/derecognized, in which the acquisition date occurs before the issuance date or effective date of the amendments, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. The adoption of this standard is not expected to have a material impact on the Company’s financial statements. FASB ASC Topic 230 “Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments” Update No. 2016-15. The FASB issued ASU No. 2016-15 in August 2016. The amendments in the ASU address eight specific cash flow issues with the objective of reducing the existing diversity in practice, as the issues are either unclear or do not have specific guidance under current GAAP. ASU 2016-15 will be effective on January 1, 2018. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. 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 amendments introduce an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loans and held-to-maturity securities), including certain off-balance sheet financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. The ASU also amends the current AFS security impairment model for debt securities. The new model will require an estimate of expected credit losses when the fair value is below the amortized cost of the asset through the use of an allowance to record estimated credit losses (and subsequent recoveries). Non-credit related losses will continue to be recognized through other comprehensive income. In addition, the amendments provide for a simplified accounting model for purchased financial assets with a more-than-insignificant amount of credit deterioration since their origination. The initial estimate of expected credit losses would be recognized through an allowance for loan losses with an offset (i.e., increase) to the cost basis of the related financial asset at acquisition. ASU 2016-13 will be effective for the Company beginning January 1, 2020. The amendments will be applied through a modified-retrospective approach, resulting in a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. A prospective transition approach is required for debt securities for which other-than-temporary impairment had been recognized before the effective date. Amounts previously recognized in accumulated other comprehensive income as of the date of adoption that relate to improvements in cash flows expected to be collected should continue to be accreted into income over the remaining life of the asset. Recoveries of amounts previously written off relating to improvements in cash flows after the date of adoption should be recorded in earnings when received. Management is currently evaluating the potential impact of ASU 2016-13 on the Company’s consolidated financial statements. FASB ASC Topic 825 “Financial Instruments – Overall” Update No. 2016-1. The FASB issued ASU No. 2016-1 in January 2016 to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The ASU will not change the guidance for classifying and measuring investments in debt securities or loans; however, it will impact how entities measure certain equity investments, recognize changes in the fair value of financial liabilities measured under the fair value option that are attributable to instrument-specific credit risk, and disclose and present financial assets and liabilities in financial statements. The main provisions require investments in equity securities to be measured at fair value through net income, unless they qualify for a new practicability exception, the equity method of accounting, or consolidation, and require fair value changes arising from changes in instrument-specific credit risk for financial liabilities that are measured under the fair value option to be recognized in other comprehensive income. The amendments will also require entities to present financial assets and financial liabilities separately, grouped by measurement category and form of financial asset in the statement of financial position or in the accompanying notes to the financial statements. Entities will also no longer have to disclose the methods and significant assumptions for financial instruments measured at amortized cost, but will be required to measure such instruments under the “exit price” notion for disclosure purposes. The amendments in this ASU are effective for the Company beginning January 1, 2018. The Company will record a cumulative-effect adjustment to beginning retained earnings as of the beginning of the first reporting period in which the guidance is adopted, with two exceptions. The amendments related to equity investments without readily determinable fair values will be effective prospectively. The requirement to use the exit price notion to measure fair value of financial instruments for disclosure purposes will also be applied prospectively. The Company does not expect a significant cumulative-effect adjustment to be recorded at adoption or any significant impact to the consolidated financial statements associated with the accounting for its current equity investments. The Company does anticipate financial statement disclosures to be impacted, specifically related to financial instruments measured at amortized cost whose fair values are disclosed under the “entry price” notion, but is currently still in the process of determining the impact. FASB ASC Topic 606 “Revenue from Contracts with Customers” Update No. 2014-9. The FASB issued ASU No. 2014-9 in May 2014 which implements a common revenue standard and clarifies the principles used for recognizing revenue. The amendments in the ASU clarify that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. As part of that principle, the entity should identify the contract(s) with the customer, identify the performance obligation(s) of the contract, determine the transaction price, allocate that transaction price to the performance obligation(s), and then recognize revenue when or as the entity satisfies the performance obligation(s). The amendments also provide additional guidance/principles associated with gross vs. net presentation (i.e., principal versus agency considerations). The amendments in ASU No. 2014-9 will be effective for the Company beginning January 1, 2018. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The amendments will be applied through the election of one of two retrospective methods. The Company intends to adopt the amendments beginning January 1, 2018 through the modified-retrospective transition method and does not expect to recognize a significant cumulative adjustment to equity upon implementation of the standard. Further, the Company does not expect a significant impact to the Company’s consolidated statements of comprehensive income or consolidated balance sheets from either a presentation or timing perspective, but is still analyzing some contracts.
