Basis of Presentation [Abstract]
Basis of Presentation	Note 1 - Basis of Presentation Citizens Financial Services, Inc. (individually and collectively with its direct and indirect subsidiaries, the “Company”) is a Pennsylvania corporation and the holding company of its wholly owned subsidiary, First Citizens Community Bank (the “Bank”), and of the Bank’s wholly owned subsidiaries, First Citizens Insurance Agency, Inc. (“First Citizens Insurance”) and 1^st Realty of PA LLC (“Realty”). Realty was formed in March of 2019 to manage and sell properties acquired by the Bank in the settlement of a bankruptcy filing with a commercial customer. The accompanying consolidated financial statements have been prepared pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”) and in conformity with U.S. generally accepted accounting principles. Because this report is based on an interim period, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Certain of the prior year amounts have been reclassified to conform with the current year presentation. Such reclassifications had no effect on net income or stockholders’ equity. All material inter‑company balances and transactions have been eliminated in consolidation. In the opinion of management of the Company, the accompanying interim financial statements at June 30, 2019 and for the periods ended June 30, 2019 and 2018 include all adjustments, consisting of only normal recurring adjustments, necessary for a fair presentation of the financial condition and the results of operations at the dates and for the periods presented. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and of revenues and expenses for the period covered by the Consolidated Income Statement. The financial performance reported for the Company for the six month period ended June 30, 2019 is not necessarily indicative of the results to be expected for the full year. This information should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The standard requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. A lessee should 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. A short-term lease is defined as one in which (a) the lease term is 12 months or less and (b) there is not an option to purchase the underlying asset that the lessee is reasonably certain to exercise. For short-term leases, lessees may elect to recognize lease payments over the lease term on a straight-line basis. ASU 2016-02 was effective for the Company on January 1, 2019. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842) - Targeted Improvements,” which, among other things, provides an additional transition method that would allow entities to not apply the guidance in ASU 2016-02 in the comparative periods presented in the financial statements and instead recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In December 2018, the FASB also issued ASU 2018-20, “Leases (Topic 842) - Narrow-Scope Improvements for Lessors,” which provides for certain policy elections and changes lessor accounting for sales and similar taxes and certain lessor costs. Upon adoption of ASU 2016-02, ASU 2018-11 and ASU 2018-20 on January 1, 2019, we recognized a right-of-use assets and related lease liabilities totaling $1,454,000 each. We elected to apply certain practical expedients provided under ASU 2016-02 whereby we did not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. We also elected not to apply the recognition requirements of ASU 2016-02 to any short-term leases (as defined by related accounting guidance). We account for lease and non-lease components separately because such amounts are readily determinable under our lease contracts. We utilized the modified-retrospective transition approach prescribed by ASU 2018-11. Certain of the Company’s leases contain options to renew the lease after the initial term. Management considers the Company’s historical pattern of exercising renewal options on leases and the positive performance of the leased locations, when determining whether it is reasonably certain that the leases will be renewed. If management concludes that there is reasonable certainty about the renewal it is included in the calculation of the remaining term of each applicable lease. The discount rate utilized in calculating the present value of the remaining lease payments for each lease was the Federal Home Loan Bank of Pittsburgh advance rate corresponding to the remaining maturity of the lease as of January 1, 2019. We have included additional disclosures in note 7.
