Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Presentation The accompanying unaudited interim consolidated condensed financial statements include LCNB Corp. ("LCNB") and its wholly-owned subsidiaries: LCNB National Bank (the "Bank") and LCNB Risk Management, Inc., a captive insurance company which was incorporated in Nevada during the second quarter 2017. All material intercompany transactions and balances are eliminated in consolidation. The unaudited interim consolidated condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and the rules and regulations of the Securities and Exchange Commission (the "SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, the unaudited interim consolidated financial statements include all adjustments (consisting of normal, recurring accruals) considered necessary for a fair presentation of financial position, results of operations, and cash flows for the interim periods, as required by Regulation S-X, Rule 10-01. The consolidated condensed balance sheet as of December 31, 2017 has been derived from the audited consolidated balance sheet as of that day. Certain prior period data presented in the financial statements have been reclassified to conform with the current year presentation. 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, the 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. Results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year ending December 31, 2018 . These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements, accounting policies, and financial notes thereto included in LCNB's 2017 Annual Report on Form 10-K filed with the SEC. Accounting Changes 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 condensed balance sheets and dividends received were included in interest on investment securities, taxable in the consolidated condensed statements of income. After adoption, equity securities are separate line items in the consolidated condensed balance sheets and the consolidated condensed statements of income. Changes in the fair value of equity securities are included in other operating income in the consolidated condensed 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. Revenue Recognition Accounting Standards Codification 606, "Revenue from Contracts with Customers" ("ASC 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 606. The adoption of ASC 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.

Business Combinations [Abstract]
Acquisitions	Acquisition 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 will merge with and into LCNB in an all-stock transaction. Immediately following the merger of CFB into LCNB, Columbus First Bank, a wholly-owned subsidiary of CFB, will be merged into the Bank. Columbus First Bank operates from one full-service office located in Worthington, Ohio. Subject to customary regulatory approvals, LCNB shareholder approval, and other conditions set forth in the Merger Agreement, the transaction is anticipated to close in the second quarter of 2018. At that time, Columbus First Bank's sole office will become a branch of the Bank. Under the terms of the Merger Agreement, which has been unanimously approved by the Board of Directors of each company, the shareholders of CFB will be entitled to receive two LCNB common shares for each outstanding CFB common share. Any unexercised stock options of CFB will be canceled in exchange for a cash payment. Based on LCNB's closing share price of $19.00 as of March 31, 2018, the transaction is valued at $38.00 for each CFB share or approximately $60.4 million in aggregate. As of March 31, 2018, CFB has 1,589,516 shares outstanding, as well as 65,724 options with a weighted average strike price of $14.06 per share. The acquisition will be accounted for in accordance with applicable accounting guidance. Accordingly, the assets and liabilities of CFB will be recorded at their estimated fair values at the acquisition date. The excess of the estimated fair value of LCNB common shares issued over the net fair values of the assets acquired, including identifiable intangible assets and liabilities assumed, will be recorded as goodwill. The results of operations will be included in the consolidated income statement from the date of the acquisition. 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 estimated fair values of the assets and liabilities have not yet been determined. The recorded amounts reflected on the historic financial records of CFB as of March 31, 2018 include total assets of approximately $324.1 million , consisting primarily of net loans of $276.9 million and interest-bearing deposits of $31.1 million . Recorded liabilities totaling approximately $290.7 million consisted primarily of deposits totaling $253.7 million .

Because LCNB does not have the intent to sell the investments and it is more likely than not that LCNB will not be required to sell the investments before recovery of their amortized cost bases, which may be at maturity, LCNB does not consider these investments to be other-than-temporarily impaired. Contractual maturities of debt securities at March 31, 2018 were as follows (in thousands). Actual maturities may differ from contractual maturities when issuers have the right to call or prepay obligations.

Realized gains or losses from the sale of securities are computed using the specific identification method. Beginning January 1, 2018, equity securities with a readily determanable fair value are carried at fair value, with changes in fair value recognized in other operating income in the consolidated condensed statements of income. Equity securities without a readily determinable fair value are measured at cost minus impairment, if any, plus or minus any changes resulting from observable price changes in orderly transactions, as defined, for identical or similar investments of the same issuer. LCNB was not aware of any impairment or observable price change adjustments that needed to be made at March 31, 2018 on its investments in equity securities without a readily determinable fair value. The amortized cost and estimated fair value of equity securities with a readily determinable fair value at March 31, 2018 are summarized as follows (in thousands): Amortized Fair Mutual funds $ 1,613 $ 1,548 Trust preferred securities 49 50 Equity securities 478 546 Total equity securities with a readily determinable fair value $ 2,140 $ 2,144 Certain information concerning changes in fair value of equity securities with a readily determinable fair value for the three months ended March 31, 2018 was as follows (in thousands): Net gains (losses) recognized $ (23 ) Less: net gains (losses) recognized on equity securities sold 23 Unrealized gains (losses) recognized and still held at period end $ (46 )

Loans	Loans Major classifications of loans at March 31, 2018 and December 31, 2017 are as follows (in thousands): March 31, 2018 December 31, 2017 Commercial and industrial $ 37,118 $ 36,057 Commercial, secured by real estate 542,890 527,947 Residential real estate 246,487 251,582 Consumer 17,176 17,450 Agricultural 12,217 15,194 Other loans, including deposit overdrafts 506 539 856,394 848,769 Deferred origination costs, net 263 291 856,657 849,060 Less allowance for loan losses 3,529 3,403 Loans, net $ 853,128 $ 845,657 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 Accounting Standards Codification ("ASC") 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. Non-accrual, past-due, and accruing restructured loans as of March 31, 2018 and December 31, 2017 are as follows (in thousands): March 31, 2018 December 31, 2017 Non-accrual loans: Commercial and industrial $ — $ — Commercial, secured by real estate 1,876 2,183 Residential real estate 691 604 Consumer — — Agricultural 177 178 Total non-accrual loans 2,744 2,965 Past-due 90 days or more and still accruing 146 — Total non-accrual and past-due 90 days or more and still accruing 2,890 2,965 Accruing restructured loans 10,366 10,469 Total $ 13,256 $ 13,434 The allowance for loan losses for the three months ended March 31, 2018 and 2017 are as follows (in thousands): Commercial & Industrial Commercial, Secured by Real Estate Residential Real Estate Consumer Agricultural Other Total Three Months Ended March 31, 2018 Balance, beginning of year $ 378 $ 2,178 $ 717 $ 76 $ 53 $ 1 $ 3,403 Provision charged to expenses 15 (131 ) 186 8 (9 ) 10 79 Losses charged off — (29 ) (35 ) (11 ) — (31 ) (106 ) Recoveries — 125 1 5 — 22 153 Balance, end of period $ 393 $ 2,143 $ 869 $ 78 $ 44 $ 2 $ 3,529 Three Months Ended March 31, 2017 Balance, beginning of year $ 350 $ 2,179 $ 885 $ 96 $ 60 $ 5 3,575 Provision charged to expenses (2 ) 90 (107 ) 23 6 5 15 Losses charged off — (262 ) (17 ) (45 ) — (30 ) (354 ) Recoveries 5 — 48 17 — 22 92 Balance, end of period $ 353 $ 2,007 $ 809 $ 91 $ 66 $ 2 $ 3,328 A breakdown of the allowance for loan losses and the loan portfolio by loan segment at March 31, 2018 and December 31, 2017 are as follows (in thousands): Commercial Commercial, Secured by Residential Consumer Agricultural Other Total March 31, 2018 Allowance for loan losses: Individually evaluated for impairment $ 11 $ 4 $ 189 $ 12 $ — $ — $ 216 Collectively evaluated for impairment 382 2,139 680 66 44 2 3,313 Acquired credit impaired loans — — — — — — — Balance, end of period $ 393 $ 2,143 $ 869 $ 78 $ 44 $ 2 $ 3,529 Loans: Individually evaluated for impairment $ 294 $ 10,879 $ 1,468 $ 46 $ 178 $ — $ 12,865 Collectively evaluated for impairment 36,603 527,656 243,526 17,240 12,053 94 837,172 Acquired credit impaired loans 258 3,989 1,961 — — 412 6,620 Balance, end of period $ 37,155 $ 542,524 $ 246,955 $ 17,286 $ 12,231 $ 506 $ 856,657 December 31, 2017 Allowance for loan losses: Individually evaluated for impairment $ 8 $ 146 $ 29 $ 8 $ — $ — $ 191 Collectively evaluated for impairment 370 2,032 688 68 53 1 3,212 Acquired credit impaired loans — — — — — — — Balance, end of period $ 378 $ 2,178 $ 717 $ 76 $ 53 $ 1 $ 3,403 Loans: Individually evaluated for impairment $ 303 $ 11,289 $ 1,351 $ 47 $ 177 $ — $ 13,167 Collectively evaluated for impairment 34,792 512,259 248,674 17,516 15,033 137 828,411 Acquired credit impaired loans 1,008 4,048 2,024 — — 402 7,482 Balance, end of period $ 36,103 $ 527,596 $ 252,049 $ 17,563 $ 15,210 $ 539 $ 849,060 The risk characteristics of LCNB's material loan portfolio segments are as follows: Commercial and Industrial Loans. 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 variable rate, with adjustment periods ranging from one month to five years . Adjustments are generally based on a publicly available index rate plus a margin. The margin varies based on the terms and collateral securing the loan. 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 two-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. Many 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 guarantors, and other factors. Commercial real estate loans are generally originated with a 75% to 80% 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 two-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 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 generally 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 collectibility 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. LCNB 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 LCNB will sustain some loss if the deficiencies are not corrected. • Doubtful – loans classified in this category have all the weaknesses inherent in loans classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. A breakdown of the loan portfolio by credit quality indicators at March 31, 2018 and December 31, 2017 is as follows (in thousands): Pass OAEM Substandard Doubtful Total March 31, 2018 Commercial & industrial $ 36,716 $ 155 $ 284 $ — $ 37,155 Commercial, secured by real estate 523,298 796 18,430 — 542,524 Residential real estate 244,998 — 1,957 — 246,955 Consumer 17,252 — 34 — 17,286 Agricultural 11,669 — 562 — 12,231 Other 506 — — — 506 Total $ 834,439 $ 951 $ 21,267 $ — $ 856,657 December 31, 2017 Commercial & industrial $ 35,683 $ 176 $ 244 $ — $ 36,103 Commercial, secured by real estate 506,833 2,180 18,583 — 527,596 Residential real estate 250,039 — 2,010 — 252,049 Consumer 17,522 — 41 — 17,563 Agricultural 14,233 — 977 — 15,210 Other 539 — — — 539 Total $ 824,849 $ 2,356 $ 21,855 $ — $ 849,060 A loan portfolio aging analysis at March 31, 2018 and December 31, 2017 is as follows (in thousands): 30-59 Days Past Due 60-89 Days Past Due Greater Than 90 Days Past Due Total Past Due Current Total Loans Receivable Total Loans Greater Than 90 Days and Accruing March 31, 2018 Commercial & industrial $ 6 $ — $ — $ 6 $ 37,149 $ 37,155 $ — Commercial, secured by real estate 59 — 335 394 542,130 542,524 — Residential real estate 420 77 576 1,073 245,882 246,955 146 Consumer 30 8 — 38 17,248 17,286 — Agricultural 185 — 177 362 11,869 12,231 — Other 42 — — 42 464 506 — Total $ 742 $ 85 $ 1,088 $ 1,915 $ 854,742 $ 856,657 $ 146 December 31, 2017 Commercial & industrial $ — $ — $ — $ — $ 36,103 $ 36,103 $ — Commercial, secured by real estate 124 — 598 722 526,874 527,596 — Residential real estate 362 135 496 993 251,056 252,049 — Consumer 29 2 — 31 17,532 17,563 — Agricultural — — 177 177 15,033 15,210 — Other 82 — — 82 457 539 — Total $ 597 $ 137 $ 1,271 $ 2,005 $ 847,055 $ 849,060 $ — Impaired loans, including acquired credit impaired loans, at March 31, 2018 and December 31, 2017 are as follows (in thousands): March 31, 2018 December 31, 2017 Recorded Investment Unpaid Principal Balance Related Allowance Recorded Investment Unpaid Principal Balance Related Allowance With no related allowance recorded: Commercial & industrial $ 264 $ 348 $ — $ 1,015 $ 1,100 $ — Commercial, secured by real estate 14,713 15,504 — 12,677 13,608 — Residential real estate 2,688 3,413 — 2,822 3,516 — Consumer 6 6 — 6 6 — Agricultural 178 178 — 177 177 — Other 412 553 — 402 554 — Total $ 18,261 $ 20,002 $ — $ 17,099 $ 18,961 $ — With an allowance recorded: Commercial & industrial $ 288 $ 288 $ 11 $ 296 $ 301 $ 8 Commercial, secured by real estate 155 155 4 2,660 2,660 146 Residential real estate 741 772 189 553 572 29 Consumer 40 40 12 41 41 8 Agricultural — — — — — — Other — — — — — — Total $ 1,224 $ 1,255 $ 216 $ 3,550 $ 3,574 $ 191 Total: Commercial & industrial $ 552 $ 636 $ 11 $ 1,311 $ 1,401 $ 8 Commercial, secured by real estate 14,868 15,659 4 15,337 16,268 146 Residential real estate 3,429 4,185 189 3,375 4,088 29 Consumer 46 46 12 47 47 8 Agricultural 178 178 — 177 177 — Other 412 553 — 402 554 — Total $ 19,485 $ 21,257 $ 216 $ 20,649 $ 22,535 $ 191 The following presents information related to the average recorded investment and interest income recognized on impaired loans, including acquired credit impaired loans, for the three months ended March 31, 2018 and 2017 (in thousands): 2018 2017 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized With no related allowance recorded: Commercial & industrial $ 639 $ 11 $ 261 $ 26 Commercial, secured by real estate 14,991 196 15,859 186 Residential real estate 2,791 45 3,219 89 Consumer 6 — 21 — Agricultural 177 — 334 — Other 407 11 463 18 Total $ 19,011 $ 263 $ 20,157 $ 319 With an allowance recorded: Commercial & industrial $ 291 $ 4 $ 322 $ 4 Commercial, secured by real estate 157 3 1,931 24 Residential real estate 755 9 704 8 Consumer 41 1 52 1 Agricultural — — — — Other — — — — Total $ 1,244 $ 17 $ 3,009 $ 37 Total: Commercial & industrial $ 930 $ 15 $ 583 $ 30 Commercial, secured by real estate 15,148 199 17,790 210 Residential real estate 3,546 54 3,923 97 Consumer 47 1 73 1 Agricultural 177 — 334 — Other 407 11 463 18 Total $ 20,255 280 $ 23,166 $ 356 Of the interest income recognized on impaired loans during the three months ended March 31, 2018 and 2017 , approximately $20,000 and $0 , respectively, were recognized on a cash basis.

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. There were no troubled debt restructurings that subsequently defaulted within twelve months of the restructuring date for the three months ended March 31, 2018 and that remained in default at period end. No impaired loans without a valuation allowance and no impaired loans with a valuation allowance at March 31, 2018 consisted of loans that were modified during the three months ended March 31, 2018 and were determined to be troubled debt restructurings. Approximately $23,000 of impaired loans without a valuation allowance and $0 of impaired loans with a valuation allowance at March 31, 2017 consisted of loans that were modified during the three months ended March 31, 2017 and were determined to be troubled debt restructurings. Mortgage loans sold to and serviced for the Federal Home Loan Mortgage Corporation and other investors are not included in the accompanying consolidated condensed balance sheets. The unpaid principal balances of those loans at March 31, 2018 and December 31, 2017 were approximately $90,630,000 and $92,818,000 , respectively.

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. Exposure to credit loss in the event of nonperformance by the other parties to financial instruments 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 March 31, 2018 and December 31, 2017 are as follows (in thousands): March 31, 2018 December 31, 2017 Commitments to extend credit: Commercial loans $ 36,896 $ 18,964 Other loans Fixed rate 3,649 2,747 Adjustable rate 1,456 1,150 Unused lines of credit: Fixed rate 19,350 20,984 Adjustable rate 113,699 90,147 Unused overdraft protection amounts on demand and NOW accounts 16,319 16,441 Standby letters of credit 259 294 Total commitments $ 191,628 $ 150,727 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. 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. LCNB evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management's credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, residential realty, income-producing commercial property, and property, plant, and equipment. 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. 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 March 31, 2018 totaled approximately $255,000 . Management believes that LCNB has sufficient liquidity to fund its lending and capital expenditure commitments. LCNB and its subsidiaries 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 the consolidated financial position or results of operations.

Retirement Benefits [Abstract]
Retirement Plans	Retirement Plans LCNB participates in a noncontributory defined benefit multi-employer retirement plan that covers substantially all regular full-time employees hired before January 1, 2009. Employees hired before this date who received a benefit reduction under certain amendments to the defined benefit retirement plan receive an automatic contribution of 5% or 7% of their annual compensation, depending on the sum of an employee's age and vesting service, into their defined contribution plans (401(k) plans), regardless of the contributions made by the employees. These contributions are made annually and these employees do not receive any employer matches to their 401(k) contributions. 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 LCNB contribution of 3% of each individual employee's annual compensation. Funding and administrative costs of the qualified noncontributory defined benefit retirement plan and 401(k) plan charged to pension and other employee benefits in the consolidated condensed statements of income for the three -month periods ended March 31, 2018 and 2017 are as follows (in thousands): For the Three Months 2018 2017 Qualified noncontributory defined benefit retirement plan $ 261 $ 260 401(k) plan 110 102 Certain highly compensated employees participate in a nonqualified defined benefit retirement plan.

The awards were made 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 of common stock. 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 ratified 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 option awards since 2012. Options granted to date under the 2002 Plan vest ratably over a five -year period and expire ten years after the date of grant.

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings per Common 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 three months ended March 31, 2018 and 2017 were calculated as follows (dollars in thousands, except share and per share data): For the Three Months Ended 2018 2017 Net income $ 2,713 $ 3,246 Less allocation of earnings and dividends to participating securities 4 2 Net income allocated to common shareholders $ 2,709 $ 3,244 Weighted average common shares outstanding, gross 10,035,871 10,001,087 Less average participating securities 15,260 6,033 Weighted average number of shares outstanding used in the calculation of basic earnings per common share 10,020,611 9,995,054 Add dilutive effect of: Stock options 7,977 7,824 Stock warrants — — Adjusted weighted average number of shares outstanding used in the calculation of diluted earnings per common share 10,028,588 10,002,878 Earnings per common share: Basic $ 0.27 $ 0.32 Diluted 0.27 0.32 There were no anti-dilutive stock options outstanding at March 31, 2018 or 2017 .

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements 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 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 March 31, 2018 and December 31, 2017 (in thousands): Fair Value Measurements at the End of the Reporting Period Using Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2018 Recurring fair value measurements: Equity securities with a readily determinable fair value: Trust preferred securities $ 50 $ 50 $ — $ — Equity securities 546 546 — — Mutual funds 39 39 — — Mutual funds measured at net asset value 1,509 1,509 — — Debt securities available-for-sale: U.S. Treasury notes 2,218 2,218 — — U.S. Agency notes 81,910 — 81,910 — U.S. Agency mortgage-backed securities 63,223 — 63,223 — Municipal securities: Non-taxable 100,706 — 100,706 — Taxable 19,837 — 19,837 — Total recurring fair value measurements $ 270,038 $ 4,362 $ 265,676 $ — Nonrecurring fair value measurements: Impaired loans 1,010 — — 1,010 December 31, 2017 Recurring fair value measurements: Equity securities with a readily determinable fair value: Trust preferred securities $ 50 $ 50 $ — $ — Equity securities 568 568 — — Mutual funds 23 23 — — Mutual funds measured at net asset value 1,519 1,519 — — Debt securities available-for-sale: U.S. Treasury notes 2,259 2,259 — — U.S. Agency notes 83,261 — 83,261 — U.S. Agency mortgage-backed securities 67,153 — 67,153 — Municipal securities: Non-taxable 102,174 — 102,174 — Taxable 20,366 — 20,366 — Total recurring fair value measurements $ 277,373 $ 4,419 $ 272,954 $ — Nonrecurring fair value measurements: Impaired loans $ 3,359 $ — $ — $ 3,359 The following table presents quantitative information about unobservable inputs used in nonrecurring level 3 fair value measurements at March 31, 2018 and December 31, 2017 (dollars in thousands): Range Fair Value Valuation Technique Unobservable Inputs High Low Weighted Average March 31, 2018 Impaired loans $ 63 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 947 Discounted cash flows Discount rate 8.25 % 4.50 % 6.88 % December 31, 2017 Impaired loans $ 1,753 Estimated sales price Adjustments for comparable properties, discounts to reflect current market conditions Not applicable 1,606 Discounted cash flows Discount rate 8.25 % 3.25 % 6.27 % Carrying amounts and estimated fair values of financial instruments as of March 31, 2018 and December 31, 2017 are as follows (in thousands): Fair Value Measurements at the End of Carrying Amount Fair Value Quoted Significant Other Observable Inputs Significant Unobservable Inputs March 31, 2018 FINANCIAL ASSETS: Cash and cash equivalents $ 17,494 $ 17,494 $ 17,494 $ — $ — Equity securities without a readily determinable fair value: Equity security 99 99 — — 99 Mutual fund 1,000 1,000 — — 1,000 Investment securities, held-to-maturity 32,502 31,722 — — 31,722 Federal Reserve Bank stock 2,732 2,732 2,732 — — Federal Home Loan Bank stock 3,638 3,638 3,638 — — Loans, net 853,128 813,225 — — 813,225 Accrued interest receivable 4,159 4,159 — 4,159 — FINANCIAL LIABILITIES: Deposits 1,123,463 1,123,997 935,667 188,330 — Long-term debt 6,219 6,383 — 6,383 — Accrued interest payable 306 306 — 306 — December 31, 2017 FINANCIAL ASSETS: Cash and cash equivalents $ 25,386 $ 25,386 $ 25,386 $ — $ — Equity securities without a readily determinable fair value: Equity security 99 99 — — 99 Mutual fund 1,000 1,000 — — 1,000 Investment securities, held-to-maturity 32,571 32,350 — — 32,350 Federal Reserve Bank stock 2,732 2,732 2,732 — — Federal Home Loan Bank stock 3,638 3,638 3,638 — — Loans, net 845,657 813,368 — — 813,368 Accrued interest receivable 3,511 3,511 — 3,511 — FINANCIAL LIABILITIES: Deposits 1,085,821 1,087,086 894,046 193,040 — Short-term borrowings 47,000 47,000 47,000 — — Long-term debt 303 307 — 307 — Accrued interest payable 329 329 — 329 — 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 March 31, 2018 and December 31, 2017 . 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 LCNB. 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 a similar investment of the same issuer. Investment securities, held-to-maturity Fair values for investment 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 stock 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 as of March 31, 2018 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 at that date discounted estimated future cash flows using rates that incorporated discounts for credit, liquidity, and marketability factors. The fair value estimate shown as of December 31, 2017 used an “entry price” approach. The fair value calculation for that date discounted estimated future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Consequently, the fair value disclosures for March 31, 2018 and December 31, 2017 are not directly comparable. 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.

The following information provides brief summaries of newly issued but not yet effective ASUs that could have an effect on LCNB’s financial position or results of operations: ASU No. 2016-02, "Leases (Topic 842)" ASU No. 2016-02 was issued in February 2016 and 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. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The amendments in this update are to be applied using a modified retrospective approach, as defined, and are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. Early application is permitted. LCNB estimates that it will recognize discounted right-of-use assets and lease liabilities totaling approximately $5 million for current leases outstanding. This projection is based on various assumptions, including the level of interest rates and no significant increases in leasing activity, that may change between now and the effective date. 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 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. ASU No. 2016-13 will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. While LCNB's Loan Committee expects that the implementation of ASU No. 2016-13 will increase the balance of the allowance for loan losses, it is continuing to evaluate the potential impact on LCNB's results of operations and financial position. The Loan Committee is currently analyzing its data collection efforts, pool segmentation, and reporting mechanisms to prepare for adoption of this ASU. 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. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" ASU No. 2017-12 was issued in August 2017 and applies to any entity that elects to apply hedge accounting in accordance with current generally accepted accounting principles. The amendments in this update better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. To meet that objective, the amendments expand and refine hedge accounting for both nonfinancial and financial risk components. The amendments are effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted. LCNB does not currently own any instruments within the scope of ASU No. 2017-12 and its adoption is not expected to have a material impact on its results of operations or financial position.
