Background and Basis Of Presentation	Background and Basis of Presentation City Holding Company ("City Holding"), a West Virginia corporation headquartered in Charleston, West Virginia, is a registered financial holding company under the Bank Holding Company Act and conducts its principal activities through its wholly-owned subsidiary, City National Bank of West Virginia ("City National"). City National is a retail and consumer-oriented community bank with 85 banking offices in West Virginia (57), Virginia (14), Kentucky (11) and Ohio (3). City National provides credit, deposit, and trust and investment management services to its customers. In addition to its branch network, City National's delivery channels include ATMs, mobile banking, debit cards, interactive voice response systems, and Internet technology. The Company’s business activities are currently limited to one reportable business segment, which is community banking. On January 9, 2015 the Company sold its insurance operations, CityInsurance, to The Hilb Group effective January 1, 2015. As a result of this sale, the Company recognized a one-time after tax gain of $5.8 million from this transaction in the first quarter of 2015. On November 6, 2015, the Company consummated the acquisition of three branch locations from American Founders Bank, Inc. (“AFB”) located in Lexington, Kentucky. The Company acquired approximately $119 million in performing loans and and assumed deposit liabilities of approximately $145 million. The Company paid AFB a deposit premium of 5.5% on non-time deposits, and 1.0% on premium loan balances acquired. The accompanying consolidated financial statements, which are unaudited, include all of the accounts of the City Holding Company and its wholly-owned subsidiaries (collectively, the "Company”). All material intercompany transactions have been eliminated. The consolidated financial statements include all adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations and financial condition for each of the periods presented. Such adjustments are of a normal recurring nature. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of the results of operations that can be expected for the year ending December 31, 2016. The Company’s accounting and reporting policies conform with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Such policies require management to make estimates and develop assumptions that affect the amounts reported in the consolidated financial statements and related footnotes. Actual results could differ from management’s estimates. The consolidated balance sheet as of December 31, 2015 has been derived from audited financial statements included in the Company’s 2015 Annual Report to Shareholders. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been omitted. These financial statements should be read in conjunction with the financial statements and notes thereto included in the 2015 Annual Report of the Company. Certain amounts in the financial statements have been reclassified. Such reclassifications had no impact on shareholders’ equity or net income for any period.
