SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES LCNB Corp. (the "Company" or “LCNB”), an Ohio corporation formed in December 1998, is a financial holding company whose principal activity is the ownership of LCNB National Bank (the "Bank"). The Bank was founded in 1877 and provides full banking services, including trust and brokerage services, to customers primarily in Southwestern Ohio and Franklin County Ohio and contiguous areas. BASIS OF PRESENTATION The consolidated financial statements include the accounts of the Company and its subsidiaries. Significant intercompany accounts and transactions are eliminated in consolidation. The accounting and reporting policies of the Company conform with U.S. generally accepted accounting principles and with general practices in the banking industry. Certain prior period data presented in the financial statements have been reclassified to conform with the current year presentation. These reclassifications had no effect on net income. USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, cash and cash equivalents include cash, balances due from banks, federal funds sold, and interest-bearing demand deposits with original maturities of twelve months or less. Deposits with other banks routinely have balances greater than FDIC insured limits. Management considers the risk of loss to be very low with respect to such deposits. INVESTMENT SECURITIES Certain municipal debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity” and recorded at amortized cost. Debt securities not classified as held-to-maturity are classified as “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income, a separate component of shareholders’ equity. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the level-yield method. Realized gains or losses from the sale of securities are recorded on the trade date and are computed using the specific identification method. Declines in the fair value of debt securities below their cost that are deemed to be other-than-temporarily impaired, and for which the Company does not intend to sell the securities and it is not more likely than not that the securities will be sold before the anticipated recovery of the impairment, are separated into losses related to credit factors and losses related to other factors. The losses related to credit factors are recognized in earnings and losses related to other factors are recognized in other comprehensive income. In estimating other than temporary impairment losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Management determined that no such impairment adjustment was required to be made in the Company's consolidated statements of income as of December 31, 2019 , 2018 , and 2017 . Beginning January 1, 2018, equity securities are measured at fair value with changes in fair value recognized in net income. Federal Home Loan Bank ("FHLB") stock is an equity interest in the Federal Home Loan Bank of Cincinnati. It can be sold only at its par value of $100 per share and only to the FHLB or to another member institution. In addition, the equity ownership rights are more limited than would be the case for a public company because of the oversight role exercised by the Federal Housing Finance Agency in the process of budgeting and approving dividends. Federal Reserve Bank stock is similarly restricted in marketability and value. Both investments are carried at cost, which is their par value. FHLB and Federal Reserve Bank stock are both subject to minimum ownership requirements by member banks. The required investments in common stock are based on predetermined formulas. LOANS The Company’s loan portfolio includes most types of commercial and industrial loans, commercial loans secured by real estate, residential real estate loans, consumer loans, agricultural loans and other types of loans. Most of the properties collateralizing the loan portfolio are located within the Company’s market area. Loans are stated at the principal amount outstanding, net of unearned income, deferred origination fees and costs, and the allowance for loan losses. Interest income is accrued on the unpaid principal balance. The delinquency status of a loan is based on contractual terms and not on how recently payments have been received. Generally, a loan is placed on non-accrual status when it is classified as impaired or there is an indication that the borrower’s cash flow may not be sufficient to make payments as they come due, unless the loan is well secured and in the process of collection. Subsequent cash receipts on non-accrual loans are recorded as a reduction of principal and interest income is recorded once principal recovery is reasonably assured. The current year's accrued interest on loans placed on non-accrual status is charged against earnings. Previous years' accrued interest is charged against the allowance for loan losses. Non-accrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer a reasonable doubt as to the timely collection of interest or principal. Loan origination fees and certain direct loan origination costs are deferred and the net amount amortized as an adjustment of loan yields. These amounts are being amortized over the lives of the related loans. In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. Loans acquired from mergers are recorded at fair value with no carryover of the acquired entity's previously established allowance for loan losses. The excess of expected cash flows over the estimated fair value of acquired loans is recognized as interest income over the remaining contractual lives of the loans using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows result in the recognition of additional interest income over the then-remaining contractual lives of the loans. Management estimates the cash flows expected to be collected at acquisition using a third-party risk model, which incorporates the estimate of key assumptions, such as default rates, severity, and prepayment speeds. Impaired loans acquired are accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") No. 310-30. Factors considered in evaluating whether an acquired loan was impaired include delinquency status and history, updated borrower credit status, collateral information, and current loan-to-value information. The difference between contractually required payments at the time of acquisition and the cash flows expected to be collected is referred to as the nonaccretable difference. The interest component of the cash flows expected to be collected is referred to as the accretable yield and is recognized as interest income over the remaining contractual life of the loan using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows will result in a reclassification from the nonaccretable difference to the accretable yield. ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. Consumer loans are charged off when they reach 120 days past due. Subsequent recoveries, if any, are credited to the allowance. The provision for loan losses is determined by management based upon its evaluation of the amount needed to maintain the allowance for loan losses at a level considered appropriate in relation to the estimated risk of losses inherent in the portfolio. Current methodology used by management to estimate the allowance takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, review of specific problem loans, historic categorical trends, current delinquency levels as related to historical levels, portfolio growth rates, changes in composition of the portfolio, the current economic environment, as well as current allowance adequacy in relation to the portfolio. Management is cognizant that reliance on historical information coupled with the cyclical nature of the economy, including credit cycles, affects the allowance. Management considers all of these factors prior to making any adjustments to the allowance due to the subjectivity and imprecision involved in allocation methodology. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are specifically reviewed for impairment. For such loans, 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 loans not specifically reviewed for impairment and homogeneous loan pools, such as residential real estate and consumer loans. The general component is measured for each loan category separately based on each category’s average of historical loss experience over a trailing sixty month period, adjusted for qualitative factors. Such qualitative factors may include current economic conditions if different from the five -year historical loss period, trends in underperforming loans, trends in volume and terms of loan categories, concentrations of credit, and trends in loan quality. A loan is considered impaired when management believes, based on current information and events, it is probable that the Bank will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement. An impaired loan is measured by the present value of expected future cash flows using the loan's effective interest rate. An impaired collateral-dependent loan may be measured based on collateral value. Smaller-balance homogeneous loans, including residential mortgage and consumer installment loans, which are not evaluated individually are collectively evaluated for impairment. PREMISES AND EQUIPMENT Premises and equipment are stated at cost less accumulated depreciation. Land is stated at cost. Depreciation is computed on both the straight-line and accelerated methods over the estimated useful lives of the assets, generally 15 to 40 years for premises and 3 to 10 years for equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Costs incurred for maintenance and repairs are expensed as incurred. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable. OTHER REAL ESTATE OWNED Other real estate owned includes properties acquired through foreclosure. Such property is held for sale and is initially recorded at fair value, less costs to sell, establishing a new cost basis. Fair value is primarily based on a property appraisal obtained at the time of transfer and any periodic updates that may be obtained thereafter. The allowance for loan losses is charged for any write down of the loan’s carrying value to fair value at the date of transfer. Any subsequent reductions in fair value and expenses incurred from holding other real estate owned are charged to other non-interest expense. Costs, excluding interest, relating to the improvement of other real estate owned are capitalized. Gains and losses from the sale of other real estate owned are included in other non-interest expense. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill is the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill is not amortized, but is instead subject to an annual review for impairment. Mortgage servicing rights on originated mortgage loans that have been sold are initially recorded at their estimated fair values. Mortgage servicing rights are amortized to loan servicing income in proportion to and over the period of estimated servicing income. Such assets are periodically evaluated as to the recoverability of their carrying value. The Company’s other intangible assets relate to core deposits acquired from business combinations. These intangible assets are amortized on a straight-line basis over their estimated useful lives. Management evaluates whether events or circumstances have occurred that indicate the remaining useful life or carrying value of the amortizing intangible should be revised. BANK OWNED LIFE INSURANCE The Company has purchased life insurance policies on certain officers of the Company. The Company is the beneficiary of these policies and has recorded the estimated cash surrender value in other assets in the consolidated balance sheets. Income on the policies, based on the increase in cash surrender value and any incremental death benefits, is included in non-interest income in the consolidated statements of income. AFFORDABLE HOUSING TAX CREDIT LIMITED PARTNERSHIP LCNB has elected to account for its investment in an affordable housing tax credit limited partnership using the proportional amortization method described in FASB Accounting Standards Update ("ASU") 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (A Consensus of the FASB Emerging Issues Task Force)." Under the proportional amortization method, an investor amortizes the initial cost of the investment to income tax expense in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. The investment in the limited partnership is included in other assets and the unfunded amount is included in accrued interest and other liabilities in LCNB's consolidated balance sheets. FAIR VALUE MEASUREMENTS Accounting guidance establishes a fair value hierarchy to prioritize the inputs to valuation techniques used to measure fair value. A financial instrument’s level within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three broad input levels are: • Level 1 – quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the reporting date; • Level 2 – inputs other than quoted prices included within level 1 that are observable for the asset or liability either directly or indirectly; and • Level 3 - inputs that are unobservable for the asset or liability. Accounting guidance permits, but does not require, companies to measure many financial instruments and certain other items, including loans and debt securities, at fair value. The decision to elect the fair value option is made individually for each instrument and is irrevocable once made. Changes in fair value for the selected instruments are recorded in earnings. The Company did not select any financial instruments for the fair value election in 2019 or 2018 . Beginning January 1, 2018, equity securities are required to be measured at fair value with changes in fair value recognized in net income. ADVERTISING EXPENSE Advertising costs are expensed as incurred and are recorded as a marketing expense, a component of non-interest expense. PENSION PLANS Eligible employees of the Company hired before 2009 participate in a multiple-employer qualified noncontributory defined benefit retirement plan. This plan is accounted for as a multi-employer plan because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Citizens National had a qualified noncontributory, defined benefit pension plan, which has been assumed by the Company, that covers eligible employees hired before May 1, 2005. This is a single employer plan. TREASURY STOCK Common shares repurchased are recorded at cost. Cost of shares retired or reissued is determined using the weighted average method. STOCK OPTIONS AND RESTRICTED STOCK AWARD PLANS The cost of employee services received in exchange for stock option grants is the grant-date fair value of the award estimated using an option-pricing model. The compensation cost for restricted stock awards is based on the market price of the Company's common stock at the date of grant multiplied by the number of shares granted that are expected to vest. The estimated cost is recognized on a straight-line basis over the period the employee is required to provide services in exchange for the award, usually the vesting period. The Company uses a Black-Scholes pricing model and related assumptions for estimating the fair value of stock option grants and a five -year vesting period for stock options and restricted stock. REVENUE RECOGNITION FASB ASC No. 606, "Revenue from Contracts with Customers" ("ASC No. 606") provides 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. The guidance enumerates five steps that entities should follow in achieving this core principle. Revenue generated from financial instruments, including loans and investment securities, are not included in the scope of ASC No. 606. The adoption of ASC No. 606 did not result in a change to the accounting for any of LCNB's revenue streams that are within the scope of the amendments. Revenue-generating activities that are within the scope of ASC 606 and that are presented as non-interest income in LCNB's consolidated statements of income include: • Fiduciary income - this includes periodic fees due from trust and investment services customers for managing the customers' financial assets. Fees are generally charged on a quarterly or annual basis and are recognized ratably throughout the period, as the services are provided on an ongoing basis. • Service charges and fees on deposit accounts - these include general service fees charged for deposit account maintenance and activity and transaction-based fees charged for certain services, such as debit card, wire transfer, or overdraft activities. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services. INCOME TAXES Deferred income taxes are determined using the asset and liability method of accounting. Under this method, the net deferred tax asset or liability is determined based on the tax effects of temporary differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Management analyzes material tax positions taken in any income tax return for any tax jurisdiction and determines the likelihood of the positions being sustained in a tax examination. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. EARNINGS PER SHARE Basic earnings per share allocated to common shareholders is calculated using the two-class method and is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is adjusted for the dilutive effects of stock based compensation and is calculated using the two-class method or the treasury stock method. The diluted average number of common shares outstanding has been increased for the assumed exercise of stock based compensation with the proceeds used to purchase treasury shares at the average market price for the period. ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS FASB Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)" ASU No. 2016-02 was issued in February 2016 and was adopted by LCNB as of January 1, 2019. It requires a lessee to recognize in the statement of financial position a liability to make lease payments ("the lease liability") and a right-of-use asset representing its right to use the underlying asset for the lease term, initially measured at the present value of the lease payments. When measuring assets and liabilities arising from a lease, the lessee should include payments to be made in optional periods only if the lessee is reasonably certain, as defined, to exercise an option to the lease or not to exercise an option to terminate the lease. Optional payments to purchase the underlying asset should be included if the lessee is reasonably certain it will exercise the purchase option. Most variable lease payments should be excluded except for those that depend on an index or a rate or are in substance fixed payments. A lessee shall classify a lease as a finance lease if it meets any of five listed criteria: 1. The lease transfers ownership of the underlying asset to the lessee by the end of the lease term. 2. The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise. 3. The lease term is for the major part of the remaining economic life of the underlying asset. 4. The present value of the sum of the lease payments and any residual value guaranteed by the lessee equals or exceeds substantially all of the fair value of the underlying asset. 5. The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. For finance leases, a lessee shall recognize in the statement of income interest on the lease liability separately from amortization of the right-of-use asset. Amortization of the right-of-use asset shall be on a straight-line basis, unless another basis is more representative of the pattern in which the lessee expects to consume the right-of-use asset’s future economic benefits. If the lease does not meet any of the five criteria, the lessee shall classify it as an operating lease and shall recognize a single lease cost on a straight-line basis over the lease term. LCNB adopted this update using a modified retrospective approach, as defined, and elected not to restate comparable prior periods. The update provides for a number of practical expedients that can be used to simplify the transition to the new standard. LCNB elected a package of practical expedients that allowed it to not reassess whether an existing contract is or contains a lease, to not reassess previous lease classifications, and to not reassess initial direct costs. LCNB also elected a practical expedient that allowed it to use hindsight when determining lease terms. LCNB did not elect a practical expedient that would have allowed it to not reassess certain land easements, as this expedient was not applicable to it. LCNB has adopted an accounting policy election to not recognize lease assets and lease liabilities for leases with a term of 12 months or less. Lease expense for such leases will generally be recognized on a straight-line basis over the lease term. ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ASU No. 2014-09 was issued in May 2014 and was adopted by LCNB as of January 1, 2018. It supersedes most current revenue recognition guidance for contracts to transfer goods or services or other nonfinancial assets. Lease contracts, insurance contracts, and most financial instruments are not included in the scope of this update. ASU No. 2014-09 provides 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. The guidance enumerates five steps that entities should follow in achieving this core principle. Additional disclosures providing information about contracts with customers are required. Adoption did not have a material impact on LCNB's results of operations or financial position. ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" ASU No. 2016-01 was issued in January 2016 and was adopted by LCNB as of January 1, 2018. It applies to all entities that hold financial assets or owe financial liabilities. It makes targeted changes to generally accepted accounting principles for public companies as follows: 1. Requires most equity investments to be measured at fair value with changes in fair value recognized in net income. 2. Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 4. Requires use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 5. Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 6. Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 7. Clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Adoption of ASU No. 2016-01 did not have a material impact on LCNB's results of operations or financial position. Upon adoption on January 1, 2018, LCNB reclassified net unrealized gain on equity securities, net of taxes, of $33,000 from accumulated other comprehensive income into retained earnings. Before adoption, equity securities were included with investment securities, available for sale in the consolidated balance sheets and dividends received were included in interest on investment securities, taxable in the consolidated statements of income. After adoption, equity securities are separate line items in the consolidated balance sheets and the consolidated statements of income. Changes in the fair value of equity securities are included in other operating income in the consolidated statements of income. ASU No. 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ASU No. 2017-07 was issued in March 2017 and was adopted by LCNB as of January 1, 2018. It applies to all employers that offer to their employees defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715. The amendments in this update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost, as defined, are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update are to be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement. Adoption of ASU No. 2017-07 did not have a material impact on LCNB's results of operations or financial position. ASU No. 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting" ASU No. 2017-09 was issued in May 2017 and was adopted by LCNB on January 1, 2018. It applies to any entity that changes the terms or conditions of a share-based payment award. The amendments in this update provide that an entity would not apply modification accounting under the guidance in Topic 718 if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The amendments are to be applied prospectively and are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Adoption of ASU No. 2017-09 did not have a material impact on LCNB's results of operations or financial position. ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ASU No. 2018-02 was issued in February 2018 and is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted and LCNB early adopted the ASU as of January 1, 2018. ASU No. 2018-02 addresses a narrow-scope financial reporting issue that arose as a consequence of the passage of H.R. 1, known as the “Tax Cuts and Jobs Act.” Generally Accepted Accounting Principles requires adjustment of deferred tax assets and liabilities for the effect of a change in tax laws or rates with the effect to be included in income from continuing operations in the reporting period that includes the enactment date. This guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income rather than in income from continuing operations. As a consequence, the tax effects of items within accumulated other comprehensive income, referred to as stranded tax effects in the update, do not reflect the appropriate tax rate. The amendments in ASU No. 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from the Tax Cuts and Jobs Act. Because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from con

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS On December 20, 2017, LCNB and Columbus First Bancorp, Inc. (“CFB”) entered into an Agreement and Plan of Merger (“Merger Agreement”) pursuant to which CFB merged with and into LCNB on May 31, 2018. LCNB entered into this transaction with the expectation that it would be accretive to income and expand its presence in the Columbus market area. Immediately following the merger of CFB into LCNB, Columbus First Bank, a wholly-owned subsidiary of CFB, merged into the Bank. Columbus First Bank operated from one full-service office located in Worthington, Ohio. That office became a branch of the Bank after the merger. Under the terms of the Merger Agreement, the shareholders of CFB received two shares of LCNB common shares for each outstanding CFB common share. Unexercised stock options of CFB were canceled in exchange for a cash payment. The merger with CFB was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration paid were recorded at their estimated fair values as of the merger date. The estimated fair values reported in LCNB's Form 10-Q for the quarterly period ended June 30, 2018 were preliminary, as the pricing study had not been finalized at that time. The following table summarizes the preliminary balances at June 30, 2018, revisions to the preliminary balances, and the balances at December 31, 2018 (in thousands): June 30, 2018 Fair Value Adjustments December 31, 2018 Consideration Paid: Common shares issued (3,253,060 shares issued at $19.55 per share) 63,598 — 63,598 Cash paid to cancel share based payment awards 783 — 783 64,381 — 64,381 Identifiable Assets Acquired: Cash and cash equivalents 13,679 — 13,679 Interest-bearing time deposits 10,350 — 10,350 Federal Home Loan Bank stock 1,207 — 1,207 Loans, net 282,748 (615 ) 282,133 Loans held for sale, net 1,819 — 1,819 Premises and equipment 102 — 102 Core deposit intangible 2,089 88 2,177 Other real estate owned 35 — 35 Deferred income taxes — 352 352 Other assets 2,022 (658 ) 1,364 Total identifiable assets acquired 314,051 (833 ) 313,218 Liabilities Assumed: Deposits 245,036 (606 ) 244,430 Short-term borrowings 10,000 — 10,000 Long-term debt 22,920 23 22,943 Deferred income taxes 200 (200 ) — Other liabilities 491 11 502 Total liabilities assumed 278,647 (772 ) 277,875 Total Identifiable Net Assets Acquired 35,404 (61 ) 35,343 Goodwill resulting from merger 28,977 61 29,038 As permitted by ASC No. 805-10-25, Business Combinations, the above estimated amounts could be adjusted up to one year after the closing date of the acquisition to reflect any new information obtained about facts and circumstances existing at the acquisition date. Any changes in the estimated fair values were recognized in the period the adjustment was identified. This adjustment period closed on May 31, 2019. There were no revisions to estimated amounts during 2019. The amount of goodwill recorded reflects LCNB's expansion in the Columbus market and related synergies that are expected to result from the acquisition and represents the excess purchase price over the estimated fair value of the net assets acquired. The goodwill will not be amortizable on LCNB's financial records and will not be deductible for tax purposes. Goodwill will be subject to an annual test for impairment and the amount impaired, if any, will be charged to expense at the time of impairment. The core deposit intangible will be amortized over the estimated weighted average economic life of the various core deposit types. Direct costs related to the acquisition were expensed as incurred and are recorded as a merger-related expense in the consolidated statements of income. CFB's results of operations are included in the consolidated statements of income from May 31, 2018 , the effective date of the merger.

Because the Company does not have the intent to sell the investments and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost, the Company does not consider these investments to be other-than-temporarily impaired.

LCNB’s commercial and industrial loan portfolio consists of loans for various purposes, including loans to fund working capital requirements (such as inventory and receivables financing) and purchases of machinery and equipment. LCNB offers a variety of commercial and industrial loan arrangements, including term loans, balloon loans, and lines of credit. Most commercial and industrial loans have a fixed rate, with maturities ranging from one year to ten years . Commercial and industrial loans are offered to businesses and professionals for short and medium terms on both a collateralized and uncollateralized basis. Commercial and industrial loans typically are underwritten on the basis of the borrower’s ability to make repayment from the cash flow of the business. Collateral, when obtained, may include liens on furniture, fixtures, equipment, inventory, receivables, or other assets. As a result, such loans involve complexities, variables, and risks that require thorough underwriting and more robust servicing than other types of loans. Commercial, Secured by Real Estate Loans. Commercial real estate loans include loans secured by a variety of commercial, retail, and office buildings, religious facilities, multifamily (more than four-family) residential properties, construction and land development loans, and other land loans. Commercial real estate loan products generally amortize over five to twenty-five years and are payable in monthly principal and interest installments. Some have balloon payments due within one to ten years after the origination date. The majority have adjustable interest rates with adjustment periods ranging from one to ten years, some of which are subject to established “floor” interest rates. Commercial real estate loans are underwritten based on the ability of the property, in the case of income producing property, or the borrower’s business to generate sufficient cash flow to amortize the debt. Secondary emphasis is placed upon global debt service, collateral value, financial strength of any and all guarantors, and other factors. Commercial real estate loans are generally originated with a 75% to 85% maximum loan to appraised value ratio, depending upon borrower occupancy. Residential Real Estate Loans. Residential real estate loans include loans secured by first or second mortgage liens on one to four-family residential property. Home equity lines of credit and mortgage loans secured by owner-occupied agricultural property are included in this category. First and second mortgage loans are generally amortized over five to thirty years with monthly principal and interest payments. Home equity lines of credit generally have a five year or less draw period with interest only payments followed by a repayment period with monthly payments based on the amount outstanding. LCNB offers both fixed and adjustable rate mortgage loans. Adjustable rate loans are available with adjustment periods ranging between one to ten years and adjust according to an established index plus a margin, subject to certain floor and ceiling rates. Home equity lines of credit have a variable rate based on the Wall Street Journal prime rate plus a margin. LCNB does not originate reverse mortgage loans or residential real estate loans generally considered to be “subprime.” Residential real estate loans are underwritten primarily based on the borrower’s ability to repay, prior credit history, and the value of the collateral. LCNB requires private mortgage insurance for first mortgage loans that have a loan to appraised value ratio of greater than 80% . Consumer Loans. LCNB’s portfolio of consumer loans generally includes secured and unsecured loans to individuals for household, family and other personal expenditures. Secured loans include loans to fund the purchase of automobiles, recreational vehicles, boats, and similar acquisitions. Consumer loans made by LCNB generally have fixed rates and terms ranging up to 72 months, depending upon the nature of the collateral, size of the loan, and other relevant factors. Consumer loans generally have higher interest rates, but pose additional risks of collectability and loss when compared to certain other types of loans. Collateral, if present, is generally subject to damage, wear, and depreciation. The borrower’s ability to repay is of primary importance in the underwriting of consumer loans. Agricultural Loans. LCNB’s portfolio of agricultural loans includes loans for financing agricultural production or for financing the purchase of equipment used in the production of agricultural products. LCNB’s agricultural loans are generally secured by farm machinery, livestock, crops, vehicles, or other agricultural-related collateral. The Company uses a risk-rating system to quantify loan quality. A loan is assigned to a risk category based on relevant information about the ability of the borrower to service the debt including, but not limited to, current financial information, historical payment experience, credit documentation, public information, and current economic trends. The categories used are: • Pass – loans categorized in this category are higher quality loans that do not fit any of the other categories described below. • Other Assets Especially Mentioned (OAEM) - loans in this category are currently protected but are potentially weak. These loans constitute a risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitute an undue risk in light of the circumstances surrounding a specific asset. • Substandard – loans in this category are inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the possibility that the Company will sustain some loss if the deficiencies are not corrected. • Doubtful – loans classified in this category have all the weaknesses inherent in loans classified 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. An analysis of the Company’s loan portfolio by credit quality indicators at December 31 is as follows (in thousands): Pass OAEM Substandard Doubtful Total 2019 Commercial & industrial $ 76,236 233 1,902 — 78,371 Commercial, secured by real estate 789,319 3,007 11,828 — 804,154 Residential real estate 319,075 267 3,513 — 322,855 Consumer 25,342 — 13 — 25,355 Agricultural 11,523 — — — 11,523 Other 1,193 — — — 1,193 Total $ 1,222,688 3,507 17,256 — 1,243,451 2018 Commercial & industrial $ 74,530 89 3,180 — 77,799 Commercial, secured by real estate 718,233 768 21,124 — 740,125 Residential real estate 344,432 — 5,106 — 349,538 Consumer 17,381 — 18 — 17,399 Agricultural 13,116 — 196 — 13,312 Other 450 — — — 450 Total $ 1,168,142 857 29,624 — 1,198,623 The Company evaluates the loan risk grading system definitions and allowance for loan loss methodology on an ongoing basis.

The Company continued to accrue interest on certain loans classified as impaired during 2019 , 2018 , and 2017 because they were restructured or considered well secured and in the process of collection. From time to time, the terms of certain loans are modified as troubled debt restructurings ("TDRs") where concessions are granted to borrowers experiencing financial difficulties. The modification of the terms of such loans may have included one, or a combination of, the following: a temporary or permanent reduction of the stated interest rate of the loan, an increase in the stated rate of interest lower than the current market rate for new debt with similar risk, forgiveness of principal, an extension of the maturity date, or a change in the payment terms.

Two commercial, secured by real estate loans to the same borrower totaling $1,236.000 that were modified during the fourth quarter 2016 subsequently defaulted in February 2017. All troubled debt restructurings are considered impaired loans. The allowance for loan loss on such restructured loans is based on the present value of future expected cash flows. Information concerning the post-modification balances of loans that were modified during the year ended December 31 and that were determined to be troubled debt restructurings follows (in thousands): 2019 2018 Impaired loans without a valuation allowance at the end of the period 252 380 Impaired loans with a valuation allowance at the end of the period 89 126 Mortgage loans sold to and serviced for the Federal Home Loan Mortgage Corporation and other investors are not included in the accompanying consolidated balance sheets.

Acquired Credit Impaired Loans [Abstract]
ACQUIRED CREDIT IMPAIRED LOANS	ACQUIRED CREDIT IMPAIRED LOANS Loans acquired through mergers are recorded at fair value with no carryover of the acquired entity's previously established allowance for loan losses. The excess of expected cash flows over the estimated fair value of acquired loans is recognized as interest income over the remaining contractual lives of the loans using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows result in the recognition of additional interest income over the then-remaining contractual lives of the loans. Impaired loans acquired are accounted for under FASB ASC No. 310-30. Factors considered in evaluating whether an acquired loan was impaired include delinquency status and history, updated borrower credit status, collateral information, and updated loan-to-value information. The difference between contractually required payments at the time of acquisition and the cash flows expected to be collected is referred to as the nonaccretable difference. The interest component of the cash flows expected to be collected is referred to as the accretable yield and is recognized as interest income over the remaining contractual life of the loan using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows will result in a reclassification from the nonaccretable difference to the accretable yield. The following table provides certain information at the acquisition date on loans acquired from CFB, not including loans considered to be impaired (in thousands): Contractually required principal at acquisition 281,639 Less fair value adjustment 1,801 Fair value of acquired loans 279,838 Contractual cash flows not expected to be collected 1,905 The following table provides details at the acquisition date on acquired impaired loans obtained through the merger with CFB that are accounted for in accordance with FASB ASC No. 310-30 (in thousands): Contractually required principal at acquisition 4,989 Less contractual cash flows not expected to be collected (nonaccretable difference) 906 Expected cash flows at acquisition 4,083 Less interest component of expected cash flows (accretable discount) 151 Fair value of acquired impaired loans 3,932 The following table provides, as of December 31, the major classifications of loans acquired that are accounted for in accordance with FASB ASC 310-30 (in thousands): 2019 2018 Acquired from First Capital Bancshares, Inc.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES LCNB is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. They involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contract amount of those instruments. The Bounce Protection product, a customer deposit overdraft program, is offered as a service and does not constitute a contract between the customer and LCNB. LCNB uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Financial instruments whose contract amounts represent off-balance-sheet credit risk at December 31 were as follows (in thousands): 2019 2018 Commitments to extend credit: Commercial loans $ 50,235 23,978 Other loans: Fixed rate 4,431 2,961 Adjustable rate 1,199 1,077 Unused lines of credit: Fixed rate 28,796 31,446 Adjustable rate 174,577 169,031 Unused overdraft protection amounts on demand and NOW accounts 16,304 16,249 Standby letters of credit 883 1,080 $ 276,425 245,822 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract or agreement. Unused lines of credit include amounts not drawn on line of credit loans. Commitments to extend credit and unused lines of credit generally have fixed expiration dates or other termination clauses. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These guarantees generally are fully secured and have varying maturities. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company, is based on management’s credit evaluation of the borrower. Collateral held varies, but may include accounts receivable; inventory; property, plant and equipment; residential realty; and income-producing commercial properties. Capital expenditures include: the construction or acquisition of new office buildings; improvements to LCNB's offices; purchases of furniture and equipment; and additions or improvements to LCNB's information technology system. Commitments outstanding for capital expenditures as of December 31, 2019 totaled approximately $1,820,000 , which includes remodeling the Main Office in Lebanon, Ohio. The Company and the Bank are parties to various claims and proceedings arising in the normal course of business. Management, after consultation with legal counsel, believes that the liabilities, if any, arising from such proceedings and claims will not be material to LCNB's consolidated financial position or results of operations.

REGULATORY MATTERS

Banking and Thrift [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS The Federal Reserve Act requires depository institutions to maintain cash reserves with the Federal Reserve Bank. In 2019 and 2018 , the Bank maintained average reserve balances of $8,518,000 and $4,982,000 , respectively. The reserve balances at December 31, 2019 and 2018 were $5,927,000 and $1,433,000 , respectively. The principal source of income and funds for LCNB Corp. is dividends paid by the Bank. The payment of dividends is subject to restriction by regulatory authorities. For 2020 , the restrictions generally limit dividends to the aggregate of net income for the year 2020 plus the net earnings retained for 2019 and 2018 . In addition, dividend payments may not reduce capital levels below minimum regulatory guidelines. At December 31, 2019 , approximately $14,598,000 of the Bank’s earnings retained was available for dividends in 2020 under this guideline. Dividends in excess of these limitations would require the prior approval of the Comptroller of the Currency. The Bank must meet certain minimum capital requirements set by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a material effect on the Company's and Bank's financial statements. The Bank’s capital amounts and classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors. A new rule requiring a Capital Conservation Buffer began phase-in on January 1, 2016 and was fully implemented at the beginning of 2019. Under the fully-implemented rule, a financial institution will need to maintain a Capital Conservation Buffer composed of Common Equity Tier 1 Capital of at least 2.5% above its minimum risk-weighted capital requirements to avoid limitations on its ability to make capital distributions, including dividend payments to shareholders and certain discretionary bonus payments to executive officers. A financial institution with a buffer below 2.5% will be subject to increasingly stringent limitations on capital distributions as the buffer approaches zero. For various regulatory purposes, financial institutions are classified into categories based upon capital adequacy: Minimum Requirement Minimum Requirement with Capital Conservation Buffer To Be Considered Well-Capitalized Ratio of Common Equity Tier 1 Capital to risk-weighted assets 4.5 % 7.0 % 6.5 % Ratio of tier 1 capital to risk-weighted assets 6.0 % 8.5 % 8.0 % Ratio of total capital (tier 1 capital plus tier 2 capital) to risk-weighted assets 8.0 % 10.5 % 10.0 % Leverage ratio (tier 1 capital to adjusted quarterly average total assets) 4.0 % N/A 5.0 % As of the most recent notification from its regulators, the Bank was categorized as "well-capitalized" under the regulatory framework for prompt corrective action. Management believes that no conditions or events have occurred since the last notification that would change the Bank's category. A summary of the regulatory capital of the Bank at December 31 follows (dollars in thousands): 2019 2018 Regulatory Capital: Shareholders' equity 222,065 215,395 Goodwill and other intangible assets (62,744 ) (63,788 ) Accumulated other comprehensive (income) loss (673 ) 4,719 Tier 1 risk-based capital 158,648 156,326 Eligible allowance for loan losses 4,045 4,046 Total risk-based capital 162,693 160,372 Capital Ratios: Common Equity Tier 1 Capital to risk-weighted assets 12.21 % 12.65 % Tier 1 capital to risk-weighted assets 12.21 % 12.65 % Total capital (tier 1 capital plus tier 2 capital) to risk-weighted assets 12.52 % 12.98 % Leverage ratio (tier 1 capital to adjusted quarterly average total assets) 10.06 % 9.96 % LCNB Corp. filed a Registration Statement on Form S-3 with the SEC on July 27, 2011 to register 400,000 shares for use in its Amended and Restated Dividend Reinvestment and Stock Purchase Plan (the “Amended Plan”).

Retirement Benefits [Abstract]
RETIREMENT PLANS	RETIREMENT PLANS Prior to January 1, 2009, the Company had a single-employer qualified noncontributory defined benefit retirement plan that covered substantially all regular full-time employees. Effective January 1, 2009, the Company redesigned the plan and merged it into a multiple-employer plan, which is accounted for as a multi-employer plan because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Employees hired on or after January 1, 2009 are not eligible to participate in this plan. Effective February 1, 2009, the Company amended the plan to reduce benefits for those whose age plus vesting service equaled less than 65 at that date. Also effective February 1, 2009, an enhanced 401(k) plan was made available to those hired on or after January 1, 2009 and to those who received benefit reductions from the amendments to the noncontributory defined benefit retirement plan. Employees hired on or after January 1, 2009 receive a 50% employer match on their contributions into the 401(k) plan, up to a maximum company contribution of 3% of each individual employee’s annual compensation. Employees who received a benefit reduction under the retirement plan amendments receive an automatic contribution of 5% or 7% of annual compensation, depending on the sum of an employee’s age and vesting service, into the 401(k) plan, regardless of the contributions made by the employees. This contribution is made annually and these employees will not receive any employer matches to their 401(k) contributions. Certain information pertaining to the qualified noncontributory defined benefit retirement plan is as follows: Legal name Pentegra Defined Benefit Plan for Financial Institutions Plan's employer identification number 13-5645888 Plan number 333 The plan is at least 80% funded as of July 1, 2019 and 2018 . A funding improvement or rehabilitation plan has not been implemented, nor has a surcharge been paid to the plan. The Company’s contributions to the qualified noncontributory defined benefit retirement plan do not represent more than 5% of total contributions to the plan. Funding and administrative costs of the qualified noncontributory defined benefit retirement plan and 401(k) plan charged to salaries and employee benefits in the consolidated statements of income for the years ended December 31 were as follows (in thousands): 2019 2018 2017 Qualified noncontributory defined benefit retirement plan $ 1,039 1,048 1,054 401(k) plan 524 457 374 The Company expects a minimum contribution of $ 205,000 to the qualified noncontributory defined benefit retirement plan in 2020 . Citizens National had a qualified noncontributory defined benefit pension plan which covered employees hired before May 1, 2005. The Company assumed this plan at the time of the merger. At December 31, 2019 , the amount of the liability for this plan was $69,000 , representing the funded status of the plan. The Bank has a benefit plan which permits eligible officers to defer a portion of their compensation. The deferred compensation balance, which accrues interest at 8% annually, is distributable in cash after retirement or termination of employment. The amount of such deferred compensation liability at December 31, 2019 and 2018 was $3,362,000 and $3,364,000 , respectively. The Bank also has supplemental income plans which provide certain employees an amount based on a percentage of average compensation, payable in accordance with individually defined schedules upon retirement. The projected benefit obligation included in other liabilities for the supplemental income plans at December 31, 2019 and 2018 is $998,000 and $1,092,000 , respectively. The average discount rate used to determine the present value of the obligations was approximately 5.2% in 2019 and 5.2% in 2018 . The service cost associated with the plans was $0 for 2019 , $0 for 2018 , and $0 for 2017 . Interest costs were $52,000 , $59,000 , and $62,000 for 2019 , 2018 , and 2017 , respectively. The deferred compensation plan and supplemental income plans are nonqualified and unfunded. Participation in each plan is limited to a select group of management. Effective February 1, 2009, the Company established a nonqualified defined benefit retirement plan, which is also unfunded, for certain highly compensated employees. The nonqualified plan ensures that participants receive the full amount of benefits to which they would have been entitled under the noncontributory defined benefit retirement plan in the absence of limits on benefit levels imposed by certain sections of the Internal Revenue Code. The components of net periodic pension cost of the nonqualified defined benefit retirement plan for the years ended December 31 are summarized as follows (in thousands): 2019 2018 2017 Service cost $ — — — Interest cost 77 69 69 Amortization of unrecognized (gain) loss — 16 — Net periodic pension cost $ 77 85 69 A reconciliation of changes in the projected benefit obligation of the nonqualified defined benefit retirement plan at December 31 follows (in thousands): 2019 2018 2017 Projected benefit obligation at beginning of year $ 1,900 1,971 1,727 Service cost — — — Interest cost 77 69 69 Actuarial (gain) or loss 122 (86 ) 238 Benefits paid (54 ) (54 ) (63 ) Projected benefit obligation at end of year $ 2,045 1,900 1,971 Amounts recognized in other liabilities in the consolidated balance sheets for the nonqualified defined benefit retirement plan at December 31, 2019 and 2018 were $2,045,000 and $1,900,000 , respectively. The accumulated benefit obligation for the nonqualified defined benefit retirement plan at December 31, 2019 and 2018 was $2,045,000 and $1,900,000 , respectively.

The awards were in the form of stock options, share awards, and/or appreciation rights. The 2002 Plan provided for the issuance of up to 200,000 shares. The 2002 Plan expired on April 16, 2012. Any outstanding unexercised options, however, continue to be exercisable in accordance with their terms. The 2015 Ownership Incentive Plan (the "2015 Plan") was approved by LCNB's shareholders at the annual meeting on April 28, 2015 and allows for stock-based awards to eligible employees, as determined by the Compensation Committee of the Board of Directors. Awards may be made in the form of stock options, appreciation rights, restricted shares, and/or restricted share units. The 2015 Plan provides for the issuance of up to 450,000 shares of common stock. The 2015 Plan will terminate on April 28, 2025 and is subject to earlier termination by the Compensation Committee. Stock-based awards may be in the form of treasury shares or newly issued shares. LCNB has not granted stock options since 2012. Option awards granted to date under the 2002 Plan vest ratably over a five year period and expire ten years after the date of grant. Stock options outstanding at December 31, 2019 were as follows: Outstanding Stock Options Exercisable Stock Options Exercise Price Range Number Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) Number Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) $11.00 - 12.99 9,904 11.96 1.1 9,904 11.96 1.1 The following table summarizes stock option activity for the years indicated: 2019 2018 2017 Weighted Aggregate Intrinsic Value (in thousands) (1) Options Weighted Aggregate Intrinsic Value (in thousands) (1) Weighted Aggregate Intrinsic Value (in thousands) (1) Outstanding at January 1, 13,278 11.98 20,265 $ 11.42 24,669 $ 12.17 Exercised (3,374 ) 12.05 (6,987 ) 10.34 (3,398 ) 14.94 Expired — — — — (1,006 ) 17.88 Outstanding at December 31, 9,904 11.96 $ 73 13,278 11.98 $ 42 20,265 11.42 $ 183 Exercisable at December 31, 9,904 11.96 73 13,278 11.98 42 20,265 11.42 183 (1) Aggregate Intrinsic Value is defined as the amount by which the current market value of the underlying stock exceeds the exercise price of the option.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE LCNB has granted restricted stock awards with non-forfeitable dividend rights, which are considered participating securities. Accordingly, earnings per share is computed using the two-class method as required by FASB ASC 260-10-45. Basic earnings per common share is calculated by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period, which excludes the participating securities. Diluted earnings per common share is adjusted for the dilutive effects of stock options, warrants, and restricted stock. The diluted average number of common shares outstanding has been increased for the assumed exercise of stock options and warrants with proceeds used to purchase treasury shares at the average market price for the period. Earnings per share for the years ended December 31 were calculated as follows (in thousands, except share and per share data): 2019 2018 2017 Net income $ 18,912 14,845 12,972 Less allocation of earnings and dividends to participating securities 31 18 7 Net income allocated to common shareholders 18,881 14,827 12,965 Weighted average common shares outstanding, gross 13,100,161 11,950,360 10,011,358 Less average participating securities 21,241 15,010 5,783 Weighted average number of shares outstanding used in the calculation of basic earnings per common share 13,078,920 11,935,350 10,005,575 Add dilutive effect of: Stock options 3,973 6,903 6,936 Adjusted weighted average number of shares outstanding used in the calculation of diluted earnings per common share 13,082,893 11,942,253 10,012,511 Earnings per common share: Basic $ 1.44 1.24 1.30 Diluted 1.44 1.24 1.29

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS LCNB measures certain assets at fair value using various valuation techniques and assumptions, depending on the nature of the asset. Fair value is defined as the price that would be received from the sale of an asset in an orderly transaction between market participants at the measurement date. The inputs to the valuation techniques used to measure fair value are assigned to one of three broad levels: • Level 1 – quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the reporting date. • Level 2 – inputs other than quoted prices included within level 1 that are observable for the asset or liability either directly or indirectly. Level 2 inputs may include quoted prices for similar assets in active markets, quoted prices for identical assets or liabilities in markets that are not active, inputs other than quoted prices (such as interest rates or yield curves) that are observable for the asset or liability, and inputs that are derived from or corroborated by observable market data. • Level 3 – inputs that are unobservable for the asset or liability. Equity Securities with a Readily Determinable Fair Value Equity securities with a readily determinable fair value are reported at fair value with changes in fair value reported in other operating income in the consolidated statements of income. Fair values for trust preferred and equity securities are determined based on market quotations (level 1). LCNB has invested in two mutual funds that are traded in active markets and their fair values are based on market quotations (level 1). Investments in another two mutual funds are measured at fair value using net asset values ("NAV") and are considered level 1 because the NAVs are determined and published and are the basis for current transactions. Debt Securities, Available-for-Sale The majority of LCNB's financial debt securities are classified as available-for-sale. The securities are reported at fair value with unrealized holding gains and losses reported net of income taxes in accumulated other comprehensive income (loss). LCNB utilizes a pricing service for determining the fair values of its debt securities. Methods and significant assumptions used to estimate fair value are as follows: • Fair value for U.S. Treasury notes are determined based on market quotations (level 1). • Fair values for the other debt securities are calculated using the discounted cash flow method for each security. The discount rates for these cash flows are estimated by the pricing service using rates observed in the market (level 2). Cash flow streams are dependent on estimated prepayment speeds and the overall structure of the securities given existing market conditions. Assets Recorded at Fair Value on a Nonrecurring Basis Assets that may be recorded at fair value on a nonrecurring basis include impaired loans, other real estate owned, and other repossessed assets. A loan is considered impaired when management believes it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impaired loans are carried at the present value of estimated future cash flows using the loan's existing rate or the fair value of collateral if the loan is collateral dependent, if this value is less than the loan balance. These inputs are considered to be level 3. Other real estate owned is adjusted to fair value, less costs to sell, upon transfer of the loan to foreclosed assets, usually based on an appraisal of the property. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. Other repossessed assets are valued at estimated sales prices, less costs to sell. The inputs for real estate owned and other repossessed assets are considered to be level 3. The following table summarizes the valuation of LCNB’s assets recorded at fair value by input levels as of December 31 (in thousands): Fair Value Measurements at the End of the Reporting Period Using Fair Value Measurements Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs 2019 Recurring fair value measurements: Equity securities with a readily determinable fair value: Equity securities $ 967 967 — — Mutual funds 45 45 — — Mutual funds measured at net asset value 1,300 1,300 — — Debt securities available-for-sale: U.S. Treasury notes 2,309 2,309 — — U.S. Agency notes 48,984 — 48,984 — U.S. Agency mortgage-backed securities 84,406 — 84,406 — Municipal securities: Non-taxable 22,321 — 22,321 — Taxable 19,980 — 19,980 — Total recurring fair value measurements $ 180,312 4,621 175,691 — Nonrecurring fair value measurements: Impaired loans $ 2,840 — — 2,840 Other real estate owned and repossessed assets 197 — — 197 Total nonrecurring fair value measurements $ 3,037 — — 3,037 2018 Recurring fair value measurement: Equity securities with a readily determinable fair value: Trust preferred securities — — — — Equity securities 519 519 — — Mutual funds 39 39 — — Mutual funds measured at net asset value 1,520 1,520 — — Debt securities available-for-sale: U.S. Treasury notes $ 2,235 2,235 — — U.S. Agency notes 78,340 — 78,340 — U.S. Agency mortgage-backed securities 55,610 — 55,610 — Municipal securities: Non-taxable 84,714 — 84,714 — Taxable 17,522 — 17,522 — Total recurring fair value measurements $ 240,499 4,313 236,186 — Nonrecurring fair value measurements: Impaired loans $ 1,039 — — 1,039 Other real estate owned and repossessed assets 244 — — 244 Total nonrecurring fair value measurements $ 1,283 — — 1,283 The following table presents quantitative information about unobservable inputs used in nonrecurring Level 3 fair value measurements at December 31, 2019 and 2018 (dollars in thousands): Range Fair Value Valuation Technique Unobservable Inputs High Low Weighted Average 2019 Impaired loans $ 1,931 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 909 Discounted cash flows Discount rate 8.25 % 4.50 % 6.83 % Other real estate owned 197 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 2018 Impaired loans $ 45 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 994 Discounted cash flows Discount rate 8.25 % 4.50 % 6.86 % Other real estate owned 244 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Carrying amounts and estimated fair values of financial instruments as of December 31 were as follows (in thousands): Fair Value Measurements at the End of Carrying Amount Fair Value Quoted Significant Other Significant 2019 FINANCIAL ASSETS: Cash and cash equivalents $ 20,765 20,765 20,765 — — Debt securities, held-to-maturity 27,525 27,888 — — 27,888 Federal Reserve Bank stock 4,652 4,652 4,652 — — Federal Home Loan Bank stock 5,203 5,203 5,203 — — Loans, net 1,239,406 1,252,156 — — 1,252,156 Accrued interest receivable — 3,911 — 3,911 — FINANCIAL LIABILITIES: Deposits 1,348,280 1,352,061 1,024,162 327,899 — Long-term debt 40,994 41,487 — 41,487 — Accrued interest payable — 705 — 705 — 2018 FINANCIAL ASSETS: Cash and cash equivalents $ 20,040 20,040 20,040 — — Debt securities, held-to-maturity 29,721 29,024 — — 29,024 Federal Reserve Bank stock 4,653 4,653 4,653 — — Federal Home Loan Bank stock 4,845 4,845 4,845 — — Loans, net 1,194,577 1,183,041 — — 1,183,041 Accrued interest receivable 4,317 4,317 — 4,317 — FINANCIAL LIABILITIES: Deposits 1,300,919 1,301,298 1,004,057 297,241 — Short-term borrowings 56,230 56,230 56,230 — — Long-term debt 47,032 48,255 — 48,255 — Accrued interest payable 690 690 — 690 — The fair values of off-balance-sheet financial instruments such as loan commitments and letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements. The fair values of such instruments were not material at December 31, 2019 and 2018 . Fair values of financial instruments are based on various assumptions, including the discount rate and estimates of future cash flows. Therefore, the fair values presented may not represent amounts that could be realized in actual transactions. In addition, because the required disclosures exclude certain financial instruments and all nonfinancial instruments, any aggregation of the fair value amounts presented would not represent the underlying value of the Company. The following methods and assumptions were used to estimate the fair value of certain financial instruments: Cash and cash equivalents The carrying amounts presented are deemed to approximate fair value. Equity securities without a readily determinable fair value Equity securities without a readily determinable fair value are measured at cost, less impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investments of the same issuer. Debt securities, held-to-maturity Fair values for debt securities, held-to-maturity are based on quoted market prices for similar securities and/or discounted cash flow analysis or other methods. Federal Home Loan Bank and Federal Reserve Bank stock The carrying value of Federal Home Loan Bank and Federal Reserve Bank stock approximates fair value based on the respective redemptive provisions. Loans The estimated fair value of loans follows the guidance in ASU 2016-01, which prescribes an “exit price” approach in estimating and disclosing fair value of financial instruments. The fair value calculation discounts estimated future cash flows using rates that incorporate discounts for credit, liquidity, and marketability factors. Deposits The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities, which approximates market rates. Borrowings The carrying amounts of federal funds purchased, repurchase agreements, and U.S. Treasury demand note borrowings are deemed to approximate fair value of short-term borrowings. For long-term debt, fair values are estimated based on the discounted value of expected net cash flows using current interest rates. Accrued interest receivable and accrued interest payable Carrying amount approximates fair value.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The consolidated financial statements include the accounts of the Company and its subsidiaries. Significant intercompany accounts and transactions are eliminated in consolidation. The accounting and reporting policies of the Company conform with U.S. generally accepted accounting principles and with general practices in the banking industry. Certain prior period data presented in the financial statements have been reclassified to conform with the current year presentation. These reclassifications had no effect on net income.
USE OF ESTIMATES	USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS For purposes of reporting cash flows, cash and cash equivalents include cash, balances due from banks, federal funds sold, and interest-bearing demand deposits with original maturities of twelve months or less. Deposits with other banks routinely have balances greater than FDIC insured limits. Management considers the risk of loss to be very low with respect to such deposits.
INVESTMENT SECURITIES	INVESTMENT SECURITIES Certain municipal debt securities that management has the positive intent and ability to hold to maturity are classified as “held-to-maturity” and recorded at amortized cost. Debt securities not classified as held-to-maturity are classified as “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income, a separate component of shareholders’ equity. Amortization of premiums and accretion of discounts are recognized as adjustments to interest income using the level-yield method. Realized gains or losses from the sale of securities are recorded on the trade date and are computed using the specific identification method. Declines in the fair value of debt securities below their cost that are deemed to be other-than-temporarily impaired, and for which the Company does not intend to sell the securities and it is not more likely than not that the securities will be sold before the anticipated recovery of the impairment, are separated into losses related to credit factors and losses related to other factors. The losses related to credit factors are recognized in earnings and losses related to other factors are recognized in other comprehensive income. In estimating other than temporary impairment losses, management considers the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. Management determined that no such impairment adjustment was required to be made in the Company's consolidated statements of income as of December 31, 2019 , 2018 , and 2017 . Beginning January 1, 2018, equity securities are measured at fair value with changes in fair value recognized in net income. Federal Home Loan Bank ("FHLB") stock is an equity interest in the Federal Home Loan Bank of Cincinnati. It can be sold only at its par value of $100 per share and only to the FHLB or to another member institution. In addition, the equity ownership rights are more limited than would be the case for a public company because of the oversight role exercised by the Federal Housing Finance Agency in the process of budgeting and approving dividends. Federal Reserve Bank stock is similarly restricted in marketability and value. Both investments are carried at cost, which is their par value. FHLB and Federal Reserve Bank stock are both subject to minimum ownership requirements by member banks. The required investments in common stock are based on predetermined formulas.
LOANS	LOANS The Company’s loan portfolio includes most types of commercial and industrial loans, commercial loans secured by real estate, residential real estate loans, consumer loans, agricultural loans and other types of loans. Most of the properties collateralizing the loan portfolio are located within the Company’s market area. Loans are stated at the principal amount outstanding, net of unearned income, deferred origination fees and costs, and the allowance for loan losses. Interest income is accrued on the unpaid principal balance. The delinquency status of a loan is based on contractual terms and not on how recently payments have been received. Generally, a loan is placed on non-accrual status when it is classified as impaired or there is an indication that the borrower’s cash flow may not be sufficient to make payments as they come due, unless the loan is well secured and in the process of collection. Subsequent cash receipts on non-accrual loans are recorded as a reduction of principal and interest income is recorded once principal recovery is reasonably assured. The current year's accrued interest on loans placed on non-accrual status is charged against earnings. Previous years' accrued interest is charged against the allowance for loan losses. Non-accrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer a reasonable doubt as to the timely collection of interest or principal. Loan origination fees and certain direct loan origination costs are deferred and the net amount amortized as an adjustment of loan yields. These amounts are being amortized over the lives of the related loans. In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses. Loans acquired from mergers are recorded at fair value with no carryover of the acquired entity's previously established allowance for loan losses. The excess of expected cash flows over the estimated fair value of acquired loans is recognized as interest income over the remaining contractual lives of the loans using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows result in the recognition of additional interest income over the then-remaining contractual lives of the loans. Management estimates the cash flows expected to be collected at acquisition using a third-party risk model, which incorporates the estimate of key assumptions, such as default rates, severity, and prepayment speeds. Impaired loans acquired are accounted for under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") No. 310-30. Factors considered in evaluating whether an acquired loan was impaired include delinquency status and history, updated borrower credit status, collateral information, and current loan-to-value information. The difference between contractually required payments at the time of acquisition and the cash flows expected to be collected is referred to as the nonaccretable difference. The interest component of the cash flows expected to be collected is referred to as the accretable yield and is recognized as interest income over the remaining contractual life of the loan using the level yield method. Subsequent decreases in expected cash flows will require additions to the allowance for loan losses. Subsequent improvements in expected cash flows will result in a reclassification from the nonaccretable difference to the accretable yield.
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is established through a provision for loan losses charged to expense. Loans are charged against the allowance for loan losses when management believes that the collectability of the principal is unlikely. Consumer loans are charged off when they reach 120 days past due. Subsequent recoveries, if any, are credited to the allowance. The provision for loan losses is determined by management based upon its evaluation of the amount needed to maintain the allowance for loan losses at a level considered appropriate in relation to the estimated risk of losses inherent in the portfolio. Current methodology used by management to estimate the allowance takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, review of specific problem loans, historic categorical trends, current delinquency levels as related to historical levels, portfolio growth rates, changes in composition of the portfolio, the current economic environment, as well as current allowance adequacy in relation to the portfolio. Management is cognizant that reliance on historical information coupled with the cyclical nature of the economy, including credit cycles, affects the allowance. Management considers all of these factors prior to making any adjustments to the allowance due to the subjectivity and imprecision involved in allocation methodology. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are specifically reviewed for impairment. For such loans, 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 loans not specifically reviewed for impairment and homogeneous loan pools, such as residential real estate and consumer loans. The general component is measured for each loan category separately based on each category’s average of historical loss experience over a trailing sixty month period, adjusted for qualitative factors. Such qualitative factors may include current economic conditions if different from the five -year historical loss period, trends in underperforming loans, trends in volume and terms of loan categories, concentrations of credit, and trends in loan quality. A loan is considered impaired when management believes, based on current information and events, it is probable that the Bank will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the loan agreement. An impaired loan is measured by the present value of expected future cash flows using the loan's effective interest rate. An impaired collateral-dependent loan may be measured based on collateral value. Smaller-balance homogeneous loans, including residential mortgage and consumer installment loans, which are not evaluated individually are collectively evaluated for impairment.
PREMISES AND EQUIPMENT	PREMISES AND EQUIPMENT Premises and equipment are stated at cost less accumulated depreciation. Land is stated at cost. Depreciation is computed on both the straight-line and accelerated methods over the estimated useful lives of the assets, generally 15 to 40 years for premises and 3 to 10 years for equipment. Leasehold improvements are amortized over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. Costs incurred for maintenance and repairs are expensed as incurred. Premises and equipment are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of a particular asset may not be recoverable.
OTHER REAL ESTATE OWNED	OTHER REAL ESTATE OWNED Other real estate owned includes properties acquired through foreclosure. Such property is held for sale and is initially recorded at fair value, less costs to sell, establishing a new cost basis. Fair value is primarily based on a property appraisal obtained at the time of transfer and any periodic updates that may be obtained thereafter. The allowance for loan losses is charged for any write down of the loan’s carrying value to fair value at the date of transfer. Any subsequent reductions in fair value and expenses incurred from holding other real estate owned are charged to other non-interest expense. Costs, excluding interest, relating to the improvement of other real estate owned are capitalized. Gains and losses from the sale of other real estate owned are included in other non-interest expense.
GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill is the excess of the purchase price over the fair value of the net identifiable assets acquired in a business combination. Goodwill is not amortized, but is instead subject to an annual review for impairment. Mortgage servicing rights on originated mortgage loans that have been sold are initially recorded at their estimated fair values. Mortgage servicing rights are amortized to loan servicing income in proportion to and over the period of estimated servicing income. Such assets are periodically evaluated as to the recoverability of their carrying value. The Company’s other intangible assets relate to core deposits acquired from business combinations. These intangible assets are amortized on a straight-line basis over their estimated useful lives. Management evaluates whether events or circumstances have occurred that indicate the remaining useful life or carrying value of the amortizing intangible should be revised.
BANK OWNED LIFE INSURANCE	BANK OWNED LIFE INSURANCE The Company has purchased life insurance policies on certain officers of the Company. The Company is the beneficiary of these policies and has recorded the estimated cash surrender value in other assets in the consolidated balance sheets. Income on the policies, based on the increase in cash surrender value and any incremental death benefits, is included in non-interest income in the consolidated statements of income.
AFFORDABLE HOUSING TAX CREDIT LIMITED PARTNERSHIP	AFFORDABLE HOUSING TAX CREDIT LIMITED PARTNERSHIP LCNB has elected to account for its investment in an affordable housing tax credit limited partnership using the proportional amortization method described in FASB Accounting Standards Update ("ASU") 2014-01, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (A Consensus of the FASB Emerging Issues Task Force)." Under the proportional amortization method, an investor amortizes the initial cost of the investment to income tax expense in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. The investment in the limited partnership is included in other assets and the unfunded amount is included in accrued interest and other liabilities in LCNB's consolidated balance sheets.
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Accounting guidance establishes a fair value hierarchy to prioritize the inputs to valuation techniques used to measure fair value. A financial instrument’s level within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three broad input levels are: • Level 1 – quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the reporting date; • Level 2 – inputs other than quoted prices included within level 1 that are observable for the asset or liability either directly or indirectly; and • Level 3 - inputs that are unobservable for the asset or liability. Accounting guidance permits, but does not require, companies to measure many financial instruments and certain other items, including loans and debt securities, at fair value. The decision to elect the fair value option is made individually for each instrument and is irrevocable once made. Changes in fair value for the selected instruments are recorded in earnings. The Company did not select any financial instruments for the fair value election in 2019 or 2018 . Beginning January 1, 2018, equity securities are required to be measured at fair value with changes in fair value recognized in net income.
ADVERTISING EXPENSE	ADVERTISING EXPENSE Advertising costs are expensed as incurred and are recorded as a marketing expense, a component of non-interest expense.
PENSION PLANS	PENSION PLANS Eligible employees of the Company hired before 2009 participate in a multiple-employer qualified noncontributory defined benefit retirement plan. This plan is accounted for as a multi-employer plan because assets contributed by an employer are not segregated in a separate account or restricted to provide benefits only to employees of that employer. Citizens National had a qualified noncontributory, defined benefit pension plan, which has been assumed by the Company, that covers eligible employees hired before May 1, 2005. This is a single employer plan.
TREASURY STOCK	TREASURY STOCK Common shares repurchased are recorded at cost. Cost of shares retired or reissued is determined using the weighted average method.
STOCK OPTIONS AND RESTRICTED STOCK AWARD PLANS	STOCK OPTIONS AND RESTRICTED STOCK AWARD PLANS The cost of employee services received in exchange for stock option grants is the grant-date fair value of the award estimated using an option-pricing model. The compensation cost for restricted stock awards is based on the market price of the Company's common stock at the date of grant multiplied by the number of shares granted that are expected to vest. The estimated cost is recognized on a straight-line basis over the period the employee is required to provide services in exchange for the award, usually the vesting period. The Company uses a Black-Scholes pricing model and related assumptions for estimating the fair value of stock option grants and a five -year vesting period for stock options and restricted stock.
REVENUE RECOGNITION	REVENUE RECOGNITION FASB ASC No. 606, "Revenue from Contracts with Customers" ("ASC No. 606") provides 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. The guidance enumerates five steps that entities should follow in achieving this core principle. Revenue generated from financial instruments, including loans and investment securities, are not included in the scope of ASC No. 606. The adoption of ASC No. 606 did not result in a change to the accounting for any of LCNB's revenue streams that are within the scope of the amendments. Revenue-generating activities that are within the scope of ASC 606 and that are presented as non-interest income in LCNB's consolidated statements of income include: • Fiduciary income - this includes periodic fees due from trust and investment services customers for managing the customers' financial assets. Fees are generally charged on a quarterly or annual basis and are recognized ratably throughout the period, as the services are provided on an ongoing basis. • Service charges and fees on deposit accounts - these include general service fees charged for deposit account maintenance and activity and transaction-based fees charged for certain services, such as debit card, wire transfer, or overdraft activities. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services.
INCOME TAXES	INCOME TAXES Deferred income taxes are determined using the asset and liability method of accounting. Under this method, the net deferred tax asset or liability is determined based on the tax effects of temporary differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. Management analyzes material tax positions taken in any income tax return for any tax jurisdiction and determines the likelihood of the positions being sustained in a tax examination. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share allocated to common shareholders is calculated using the two-class method and is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is adjusted for the dilutive effects of stock based compensation and is calculated using the two-class method or the treasury stock method. The diluted average number of common shares outstanding has been increased for the assumed exercise of stock based compensation with the proceeds used to purchase treasury shares at the average market price for the period.
RECENT ACCOUNTING PRONOUNCEMENTS	ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS FASB Accounting Standards Update ("ASU") No. 2016-02, "Leases (Topic 842)" ASU No. 2016-02 was issued in February 2016 and was adopted by LCNB as of January 1, 2019. It requires a lessee to recognize in the statement of financial position a liability to make lease payments ("the lease liability") and a right-of-use asset representing its right to use the underlying asset for the lease term, initially measured at the present value of the lease payments. When measuring assets and liabilities arising from a lease, the lessee should include payments to be made in optional periods only if the lessee is reasonably certain, as defined, to exercise an option to the lease or not to exercise an option to terminate the lease. Optional payments to purchase the underlying asset should be included if the lessee is reasonably certain it will exercise the purchase option. Most variable lease payments should be excluded except for those that depend on an index or a rate or are in substance fixed payments. A lessee shall classify a lease as a finance lease if it meets any of five listed criteria: 1. The lease transfers ownership of the underlying asset to the lessee by the end of the lease term. 2. The lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise. 3. The lease term is for the major part of the remaining economic life of the underlying asset. 4. The present value of the sum of the lease payments and any residual value guaranteed by the lessee equals or exceeds substantially all of the fair value of the underlying asset. 5. The underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. For finance leases, a lessee shall recognize in the statement of income interest on the lease liability separately from amortization of the right-of-use asset. Amortization of the right-of-use asset shall be on a straight-line basis, unless another basis is more representative of the pattern in which the lessee expects to consume the right-of-use asset’s future economic benefits. If the lease does not meet any of the five criteria, the lessee shall classify it as an operating lease and shall recognize a single lease cost on a straight-line basis over the lease term. LCNB adopted this update using a modified retrospective approach, as defined, and elected not to restate comparable prior periods. The update provides for a number of practical expedients that can be used to simplify the transition to the new standard. LCNB elected a package of practical expedients that allowed it to not reassess whether an existing contract is or contains a lease, to not reassess previous lease classifications, and to not reassess initial direct costs. LCNB also elected a practical expedient that allowed it to use hindsight when determining lease terms. LCNB did not elect a practical expedient that would have allowed it to not reassess certain land easements, as this expedient was not applicable to it. LCNB has adopted an accounting policy election to not recognize lease assets and lease liabilities for leases with a term of 12 months or less. Lease expense for such leases will generally be recognized on a straight-line basis over the lease term. ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" ASU No. 2014-09 was issued in May 2014 and was adopted by LCNB as of January 1, 2018. It supersedes most current revenue recognition guidance for contracts to transfer goods or services or other nonfinancial assets. Lease contracts, insurance contracts, and most financial instruments are not included in the scope of this update. ASU No. 2014-09 provides 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. The guidance enumerates five steps that entities should follow in achieving this core principle. Additional disclosures providing information about contracts with customers are required. Adoption did not have a material impact on LCNB's results of operations or financial position. ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" ASU No. 2016-01 was issued in January 2016 and was adopted by LCNB as of January 1, 2018. It applies to all entities that hold financial assets or owe financial liabilities. It makes targeted changes to generally accepted accounting principles for public companies as follows: 1. Requires most equity investments to be measured at fair value with changes in fair value recognized in net income. 2. Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. 3. Eliminates the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. 4. Requires use of the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 5. Requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. 6. Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. 7. Clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Adoption of ASU No. 2016-01 did not have a material impact on LCNB's results of operations or financial position. Upon adoption on January 1, 2018, LCNB reclassified net unrealized gain on equity securities, net of taxes, of $33,000 from accumulated other comprehensive income into retained earnings. Before adoption, equity securities were included with investment securities, available for sale in the consolidated balance sheets and dividends received were included in interest on investment securities, taxable in the consolidated statements of income. After adoption, equity securities are separate line items in the consolidated balance sheets and the consolidated statements of income. Changes in the fair value of equity securities are included in other operating income in the consolidated statements of income. ASU No. 2017-07, "Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ASU No. 2017-07 was issued in March 2017 and was adopted by LCNB as of January 1, 2018. It applies to all employers that offer to their employees defined benefit pension plans, other postretirement benefit plans, or other types of benefits accounted for under Topic 715. The amendments in this update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost, as defined, are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update are to be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement. Adoption of ASU No. 2017-07 did not have a material impact on LCNB's results of operations or financial position. ASU No. 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting" ASU No. 2017-09 was issued in May 2017 and was adopted by LCNB on January 1, 2018. It applies to any entity that changes the terms or conditions of a share-based payment award. The amendments in this update provide that an entity would not apply modification accounting under the guidance in Topic 718 if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The amendments are to be applied prospectively and are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Adoption of ASU No. 2017-09 did not have a material impact on LCNB's results of operations or financial position. ASU No. 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" ASU No. 2018-02 was issued in February 2018 and is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted and LCNB early adopted the ASU as of January 1, 2018. ASU No. 2018-02 addresses a narrow-scope financial reporting issue that arose as a consequence of the passage of H.R. 1, known as the “Tax Cuts and Jobs Act.” Generally Accepted Accounting Principles requires adjustment of deferred tax assets and liabilities for the effect of a change in tax laws or rates with the effect to be included in income from continuing operations in the reporting period that includes the enactment date. This guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income rather than in income from continuing operations. As a consequence, the tax effects of items within accumulated other comprehensive income, referred to as stranded tax effects in the update, do not reflect the appropriate tax rate. The amendments in ASU No. 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from the Tax Cuts and Jobs Act. Because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. Upon adoption, LCNB reclassified stranded tax effects of $492,000 into retained earnings as of January 1, 2018. RECENT ACCOUNTING PRONOUNCEMENTS NOT YET EFFECTIVE ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" ASU No. 2016-13 was issued in June 2016 and, once effective, will significantly change current guidance for recognizing impairment of financial instruments. Current guidance requires an "incurred loss" methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. ASU No. 2016-13 replaces the incurred loss impairment methodology with a new current expected credit loss ("CECL") methodology that reflects expected credit losses over the lives of the loans and requires consideration of a broader range of information to inform credit loss estimates. The ASU requires an organization to estimate all expected credit losses for financial assets measured at amortized cost, including loans and held-to-maturity debt securities, based on historical experience, current conditions, and reasonable and supportable forecasts. Additional disclosures are required. ASU No. 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. Under the new guidance, entities will determine whether all or a portion of the unrealized loss on an available-for-sale debt security is a credit loss. Any credit loss will be recognized as an allowance for credit losses on available-for-sale debt securities rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. As a result, entities will recognize improvements to estimated credit losses on available-for-sale debt securities immediately in earnings rather than as interest income over time, as currently required. ASU No. 2016-13 eliminates the current accounting model for purchased credit impaired loans and debt securities. Instead, purchased financial assets with credit deterioration will be recorded gross of estimated credit losses as of the date of acquisition and the estimated credit losses amounts will be added to the allowance for credit losses. Thereafter, entities will account for additional impairment of such purchased assets using the models listed above. Originally, ASU No. 2016-13 would have taken effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. At their meeting on October 16, 2019, FASB approved a final ASU delaying the effective date for several major standards, including ASU No. 2016-13, if certain qualifications are met. The new effective date for SEC filers eligible to be smaller reporting companies ("SRC"), as defined, will be fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. As an SRC, LCNB intends to adopt ASU No. 2016-13 for the fiscal year, and interim periods within the fiscal year, beginning after December 15, 2022. LCNB has created a cross-functional CECL Committee, which reports to the Audit Committee, composed of members from the lending, trust, and finance departments. The CECL Committee has selected a vendor to assist in implementation of and ongoing compliance with the new requirements. It has completed analyzing its data collection efforts, selected a calculation model, and is currently analyzing its pool segmentation and reporting mechanisms for adoption of the new methodology. While the committee and management expect that the implementation of ASU No. 2016-13 will increase the balance of the allowance for loan losses, they are continuing to evaluate the potential impact on LCNB's results of operations and financial position. The financial statement impact of this new standard cannot be reasonably estimated at this time. ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" ASU No. 2017-04 was issued in January 2017 and applies to public and other entities that have goodwill reported in their financial statements. To simplify the subsequent measurement of goodwill, this ASU eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities, including unrecognized assets and liabilities, following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. A public business entity that is an SEC filer should adopt the amendments in this update on a prospective basis for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Adoption of ASU No. 2017-04 is not expected to have a material impact on LCNB's results of operations or financial position. ASU No. 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement" ASU No. 2018-13 was issued in August 2018 and applies to all entities that are required to make disclosures about recurring or nonrecurring fair value measurements. The amendments in this update modify fair value disclosure requirements, including the deletion, modification, and addition of certain targeted disclosures. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of the update and delay adoption of the additional disclosures until the effective date. The amendments are to be applied on a retrospective basis to all periods presented upon adoption, except for certain amendments described in the update that are to be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. Adoption of ASU No. 2018-13 will not have a material impact on LCNB's results of operations or financial position. ASU No. 2018-14, "Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans" ASU No. 2018-14 was issued in August 2018. The amendments in this update modify disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans, including the deletion, modification, and addition of certain targeted disclosures. The amendments are effective for public business entities for fiscal years beginning after December 15, 2020. Early adoption is permitted. The amendments are to be applied on a retrospective basis to all periods presented upon adoption. Adoption of ASU No. 2018-14 will not have a material impact on LCNB's results of operations or financial position. ASU No. 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract" ASU No. 2018-15 was issued in August 2018 and applies to entities that are a customer in a hosting arrangement, as defined, that is accounted for as a service contract. The amendments in this update require an entity (customer) in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40 to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. Capitalized implementation costs are to be expensed over the term of the hosting arrangement. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The amendments can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Adoption of ASU No. 2018-15 is not expected to have a material impact on LCNB's results of operations or financial position. ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes" ASU No. 2019-12 was issued in December 2019 and simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and clarifies and amends certain other guidance. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. Adoption of ASU No. 2019-12 is not expected to have a material impact on LCNB's results of operations or financial position.
