Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS Principles of Consolidation: Farmers National Banc Corp. (“Company”) is a Financial Holding Company registered under the Bank Holding Company Act of 1956, as amended. The Company provides full banking services through its nationally chartered subsidiary, The Farmers National Bank of Canfield (“Bank”). The consolidated financial statements also include the accounts of the Bank’s subsidiaries; Farmers National Insurance, LLC (“Insurance”) and Farmers of Canfield Investment Co. (“Investments”). The Company provides trust and retirement consulting services through its subsidiary, Farmers Trust Company (“Trust”), and insurance services through the Bank’s subsidiary, Insurance. Farmers National Captive, Inc. (“Captive”) is a wholly-owned insurance subsidiary of the Company that provides property and casualty insurance coverage to the Company and its subsidiaries. The Captive pools resources with eleven other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves and to provide insurance where not currently available or economically feasible in today’s insurance market place. The consolidated financial statements include the accounts of the Company, the Bank and its subsidiaries, along with the Trust and Captive. All significant intercompany balances and transactions have been eliminated in the consolidation. Corporate Reorganization: On July 1, 2019, Trust acquired all shares of National Associates, Inc. (“NAI”) from the Company through a corporate reorganization. The Company was the sole shareholder of Trust and NAI before the reorganization. The entities were combined into one reporting unit and one operating segment and began reporting as one unit, for both internal and external reports, during the third quarter of 2019. The combination is part of the Company’s plan to increase efficiencies within the different business lines. Basis of Presentation: The unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. The financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2019 Annual Report to Shareholders included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The interim consolidated financial statements include all adjustments (consisting of only normal recurring items) that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods presented. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year. Certain items included in the prior period financial statements were reclassified to conform to the current period presentation. There was no effect on net income or total stockholders’ equity. Estimates: The preparation of financial statements in conformity with U.S. GAAP 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. Segments: The Company provides a broad range of financial services to individuals and companies in northeastern Ohio and western Pennsylvania. Operations are managed and financial performance is primarily aggregated and reported in two lines of business, the Bank segment and the Trust segment. During the third quarter of 2019 the Company merged the Retirement Consulting segment into the Trust segment. In prior periods segment reporting was reported in three segments. Equity: There are 50,000,000 shares authorized and available for issuance as of September 30, 2020. Outstanding shares at September 30, 2020 were 28,186,243. Comprehensive Income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income consists of unrealized gains and losses on securities available for sale which are recognized as components of stockholders’ equity, net of tax effect. Risks and Uncertainties: The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The spread of the outbreak has caused disruptions in the economy and has disrupted banking and other financial activity in the areas in which the Company operates. While there has been no material impact to the Company’s business continuity or financial condition the possible of future challenges exist. Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the Coronavirus Aid, Relief and Economic Security Act (“CARES”) was signed into law at the end of March 2020 as a $2 trillion legislative package. The goal of the CARES Act was to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also included extensive emergency funding for hospitals and providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts have had a material impact on the Company’s operations. Congress and the President have not come to an agreement for a second legislative aid package. If and when any new legislation becomes law is unknown at this time. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. As the global response to contain COVID-19 continues or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19 will have on the Company’s operations, the Company will disclose potentially material items of which it is aware. Financial position and results of operations: The Company’s fee income declined and could be reduced further due to COVID-19. In keeping with guidance from regulators, the Company worked with COVID-19 affected customers to waive fees from a variety of sources, such as, but not limited to, insufficient funds and overdraft fees, ATM fees, account maintenance fees, etc. During the nine month period ended at September 30, 2020 the Company waived $780 thousand in fees. The Company recognizes the breadth of the economic impact is likely to continue impacting its fee income in future periods. The Company’s interest income and net interest income margin decreased and could be reduced further due to COVID-19. In keeping with guidance from regulators, the Company is working with COVID-19 affected borrowers to defer their payments. Currently the Bank has five loans remaining that are deferring their loan payments. While interest and fees will still accrue to income, through normal GAAP accounting, should eventual credit losses on these deferred payments emerge, interest income and fees accrued would need to be reversed. In such a scenario, interest income in future periods could be negatively impacted. At this time, the Company is unable to project the materiality of such an impact, but recognizes the breadth of the economic impact may affect its borrowers’ ability to repay in future periods. Capital and liquidity: While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by further credit losses. The Company relies on cash on hand as well as dividends from its subsidiaries. If the Company’s capital deteriorates such that its subsidiary bank is unable to pay dividends to it for an extended period of time, the Company may not be able to pay dividends to shareholders. The Company maintains access to multiple sources of liquidity. Wholesale funding markets have remained open. Rates for short term funding have recently been low but if funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Company’s deposit customers to withdraw their funds, the Company might become more reliant on volatile or more expensive sources of funding. New Accounting Standards: Reacting to the global markets’ planned shift away from using major interbank reference rates, including the London Interbank Offered Rate (LIBOR), the FASB recently issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, to ease the burden of accounting for contract modifications related to reference rate reform. The amendments in ASU 2020-04 create a new Topic in the Codification, ASC 848, Reference Rate Reform, which contains guidance that is designed to simplify how entities account for contracts that are modified to replace LIBOR or other benchmark interest rates with new rates. The amendments in ASU 2020-04 give entities the option to apply expedients and exceptions to contract modifications that are made until December 31, 2022, if certain criteria are met. If adopted, these amendments and exceptions should be applied to all eligible modifications to contracts that are accounted for under an ASC Topic or industry Subtopic. The guidance in ASC 848 will not apply to any contract modifications made after December 31, 2022. Management is still evaluating the ASU and has not adopted it as of September 30, 2020. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. Instead, under the new guidance, an entity is to perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted this ASU on January 1, 2020. The adoption of this guidance did not have an impact on the Company’s Consolidated Financial Statements. In June 2016, the FASB issued ASU 2016-13: Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (modified by ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments Credit Losses). The ASU requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques changed to reflect the full amount of expected credit losses. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Additionally, the ASU amends the accounting for credit losses on available for sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 is effective for public companies for annual periods beginning after December 15, 2019. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In accordance with the accounting relief provisions of CARES, the Bank has postponed the adoption of the current expected credit losses (“CECL”) accounting standards, primarily due to the impact that the COVID-19 pandemic is having on the economy and the lack of reasonable and supportable economic forecasts. Had the Company adopted CECL as of January 1, 2020, the increase to the allowance for loan losses estimated to have ranged from 15% to 20% of the amount recorded at December 31, 2019, which did not consider potential COVID-19 pandemic related impacts. In February 2016, FASB issued ASU 2016-02 (Topic 842): Leases. The main objective of ASU 2016-02 is to provide users with useful, transparent, and complete information about leasing transactions. ASU 2016-02 requires the rights and obligations associated with leasing arrangements be reflected on the balance sheet in order to increase transparency and comparability among organizations. Under the updated guidance, lessees are required to recognize a right-to-use asset and a liability to make a lease payment and disclose key information about leasing arrangements. ASU 2016-02 is effective for public companies for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted this ASU on January 1, 2019. As disclosed in the lease footnote, certain leases that the Company has in place required the capitalization of $3.6 million on the balance sheet as an asset and a related liability in the same amount with no income statement effect at January 1, 2019.
