The Company adopted this guidance via the modified retrospective approach, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees, interchange fees, and merchant income. The Company also completed an evaluation of certain costs related to these revenue streams to determine whether such costs should be presented gross versus net. Based on these assessments, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary.

NOTE 1. General

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and 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 accounting principles generally accepted in the United States of America.

In the opinion of management, the accompanying financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position at June 30, 2018 and December 31, 2017, the results of operations for the three and six months ended June 30, 2018 and 2017, and cash flows for the six months ended June 30, 2018 and 2017. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Form 10-K”).

Eagle Financial Services, Inc. (the "Company") owns 100% of Bank of Clarke County (the “Bank”). The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions between the Company and the Bank have been eliminated.

Certain amounts in the consolidated financial statements have been reclassified to conform to current year presentations. None of the reclassifications were of a material nature and they had no effect on prior year net income or shareholders' equity.

On January 1, 2018, the Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers: Topic 606." This ASU revised guidance for the recognition, measurement, and disclosure of revenue from contracts with customers.
