Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 86 banking offices in West Virginia ( 57 ), Virginia ( 14 ), Kentucky ( 12 ) and southeastern Ohio ( 3 ). City National provides credit, deposit, and trust and investment management services to its customers in a broad geographical area that includes many rural and small community markets in addition to larger cities including Charleston (WV), Huntington (WV), Martinsburg (WV), Winchester (VA), Staunton (VA), Virginia Beach (VA), Ashland (KY) and Lexington (KY). In addition to its branch network, City National's delivery channels include automated-teller-machines ("ATMs"), interactive-teller machines ("ITMs"), 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. The accompanying consolidated financial statements, which are unaudited, include all of the accounts of 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, 2018 are not necessarily indicative of the results of operations that can be expected for the year ending December 31, 2018 . 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, 2017 has been derived from audited financial statements included in the Company’s 2017 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 2017 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.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted: In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." This standard clarifies the principles for recognizing revenue and developed a common revenue standard. The core principle of the standard is 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 and services. To achieve that core principle, an entity should apply the following steps: (i) identifying the contract or contracts with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The FASB also issued several amendments to the standard, including clarifications relating to performance obligations and licensing implementation guidance and reporting gross versus net revenue. The Company adopted the standard effective January 1, 2018 using the modified retrospective approach, but did not record a cumulative effect adjustment to opening retained earnings given the immaterial impact. As part of the adoption, the Company evaluated the terms of the contracts that supported each of the revenue streams that were within the scope of ASU 2014-09 and determined that the adoption did not significantly change the way the Company recognizes revenue from each stream. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This standard makes several modifications to Subtopic 825-10 including the elimination of the available-for-sale classification of equity investments, and requires equity investments with readily determinable fair values to be measured at fair value with changes in fair value recognized in net income. This ASU became effective for the Company for interim and annual periods on January 1, 2018. The adoption of ASU No. 2016-01 did not have a material impact on the Company's financial statements. During the three months ended March 31, 2018 , a $0.2 million gain was recognized in other income in the consolidated statements of income as a result of the change in the fair value of equity and perpetual preferred securities due to the adoption of ASU 2016-01. Additionally, $2.7 million , net of deferred taxes, was reclassified from other comprehensive income to retained earnings on the consolidated balance sheets to recognize the prior period unrealized gain position of these securities (see Note C Investments and Note J Accumulated Other Comprehensive Loss). In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." This amendment clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU became effective for the Company on January 1, 2018. The adoption of ASU No. 2017-01 did not have a material impact on the Company's financial statements. In March 2017, the FASB issued ASU No. 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." This amendment requires that an employer disaggregate the service cost component from the other components of net benefit cost and also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement. This ASU became effective for the Company on January 1, 2018. The adoption of ASU No. 2017-07 did not have a material impact on the Company's financial statements. In May 2017, the FASB issued ASU No. 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting." This amendment provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASU No. 2016-09. This ASU became effective for the Company on January 1, 2018. The adoption of ASU No. 2017-09 did not have a material impact on the Company’s financial statements. In September 2017, the FASB issued ASU No. 2017-13, "Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842)." This amendment provides modifications to previously issued ASUs 2014-09 and 2016-02. The adoption of ASU No. 2017-13 did not have a material impact on the Company's financial statements. In November 2017, the FASB issued ASU No. 2017-14, "Income Statement—Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from Contracts with Customers (Topic 606)." This amendment supersedes various SEC paragraphs and amends an SEC paragraph pursuant to the issuance of Staff Accounting Bulletin No. 116. The adoption of ASU No. 2017-14 did not have a material impact on the Company's financial statements. Pending Adoption: In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” This standard requires organizations to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing requirements for leases that were historically classified as operating leases under previous generally accepted accounting principals. This ASU will become effective for the Company for interim and annual periods on January 1, 2019. The Company's preliminary evaluation indicates that the adoption of ASU 2016-02 will have an immaterial impact on the Company's consolidated balance sheet. However, the Company continues to evaluate the extent of the potential impact the new guidance will have on the Company's consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." This standard replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The new current expected credit losses model (CECL) will apply to the allowance for loan losses, available-for-sale and held to maturity debt securities, purchased financial assets with credit deterioration and certain off-balance sheet credit exposures. This ASU will become effective for the Company for interim and annual periods on January 1, 2020. Management is currently evaluating the potential impact of ASU No. 2016-13 on the Company's financial statements. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This amendment simplifies the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This ASU will become effective for the Company on January 1, 2020. The adoption of ASU No. 2017-04 is not expected to have a material impact on the Company's financial statements. In March 2017, the FASB issued ASU No. 2017-08, "Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities." The amendments in this update shorten the amortization period for certain callable debt securities held at a premium and require the premium to be amortized to the earliest call date. This ASU will become effective for the Company on January 1, 2019. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's financial statements. In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." This amendment expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This ASU will become effective for the Company on January 1, 2019. The adoption of ASU No. 2017-12 is not expected to have a material impact on the Company's financial statements. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." This amendment permits entities to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act ("TCJA") to retained earnings. The guidance is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permissible. The Company elected to early adopt this amendment as of December 31, 2017 and the December 31, 2017 balance sheet reflects this adoption.

Marketable equity securities consist of investments made by the Company in equity positions of various regional community banks. Included within this portfolio are ownership positions in the following community bank holding companies: First National Corporation (FXNC) ( 4% ) and Eagle Financial Services, Inc. (EFSI) ( 1.5% ). Securities with limited marketability, such as stock in the Federal Reserve Bank ("Federal Reserve") and the Federal Home Loan Bank ("FHLB"), are carried at cost and are reported as non-marketable equity securities in the table above. Certain investment securities owned by the Company were in an unrealized loss position (i.e., amortized cost basis exceeded the estimated fair value of the securities). The following table shows the gross unrealized losses and fair value of the Company’s investments aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position (in thousands): March 31, 2018 Less Than Twelve Months Twelve Months or Greater Total Estimated Fair Value Unrealized Loss Estimated Fair Value Unrealized Loss Estimated Fair Value Unrealized Loss Securities available-for-sale: Obligations of states and political subdivisions $ 24,204 $ 211 $ 18,955 $ 799 $ 43,159 $ 1,010 Mortgage-backed securities: U.S. Government agencies 266,824 7,208 134,047 7,904 400,871 15,112 Corporate securities — — — — — — Investment funds 1,500 60 — — 1,500 60 Total available-for-sale $ 292,528 $ 7,479 $ 153,002 $ 8,703 $ 445,530 $ 16,182 Securities held-to-maturity: Mortgage-backed securities U.S. Government Agencies $ 39,433 $ 219 $ — $ — $ 39,433 $ 219 Total held-to-maturity $ 39,433 $ 219 $ — $ — $ 39,433 $ 219 December 31, 2017 Less Than Twelve Months Twelve Months or Greater Total Estimated Fair Value Unrealized Loss Estimated Fair Value Unrealized Loss Estimated Fair Value Unrealized Loss Securities available-for-sale: Obligations of states and political subdivisions $ 4,913 $ 28 $ 19,440 $ 379 $ 24,353 $ 407 Mortgage-backed securities: U.S. Government agencies 172,807 1,887 140,226 5,418 313,033 7,305 Trust preferred securities 4,475 54 — — 4,475 54 Corporate securities 3,357 49 2,350 74 5,707 123 Investment funds 1,500 36 — — 1,500 36 Total available-for-sale $ 187,052 $ 2,054 $ 162,016 $ 5,871 $ 349,068 $ 7,925 Securities held-to-maturity Mortgage-backed securities U.S. Government agencies $ 7,182 $ 25 $ — $ — $ 7,182 $ 25 Total held-to-maturity $ 7,182 $ 25 $ — $ — $ 7,182 $ 25 During the three months ended March 31, 2018 and 2017 , the Company had no investment impairment losses. At March 31, 2018 , the cumulative amount of credit-related investment impairment losses that have been recognized by the Company on investments that remain in the Company's investment portfolio as of that date was $1.8 million ( $0.2 million related to the Company's debt securities and $1.6 million related to the Company's equity securities). Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other-than-temporary would be reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers, among other things (i) the length of time and the extent to which the fair value has been less than cost; (ii) the financial condition, capital strength, and near-term (within 12 months) prospects of the issuer, including any specific events which may influence the operations of the issuer such as changes in technology that may impair the earnings potential of the investment or the discontinuance of a segment of the business that may affect the future earnings potential; (iii) the historical volatility in the market value of the investment and/or the liquidity or illiquidity of the investment; (iv) adverse conditions specifically related to the security, an industry, or a geographic area; and (v) the intent to sell the investment security and if it’s more likely than not that the Company will not have to sell the security before recovery of its cost basis. In addition, management also employs a continuous monitoring process in regards to its marketable equity securities, specifically its portfolio of regional community bank holdings. Although the regional community bank stocks that are owned by the Company are publicly traded, the trading activity for these stocks is minimal, with trading volumes of less than 0.4% of each respective company being traded on a daily basis. As part of management’s review process for these securities, management reviews the financial condition of each respective regional community bank for any indications of financial weakness. Management has the ability and intent to hold the securities classified as held-to-maturity until they mature, at which time the Company expects to receive full value for the securities. Furthermore, as of March 31, 2018 , management does not intend to sell an impaired security and it is not more than likely that it will be required to sell the security before the recovery of its amortized cost basis. The unrealized losses on debt securities are primarily the result of interest rate changes, credit spread fluctuations on agency-issued mortgage related securities, general financial market uncertainty and unprecedented market volatility. These conditions should not prohibit the Company from receiving its contractual principal and interest payments on its debt securities. The fair value is expected to recover as the securities approach their maturity date or repricing date. As of March 31, 2018 , management believes the unrealized losses detailed in the table above are temporary and no additional impairment loss has been recognized in the Company’s consolidated income statement. Should the impairment of any of these securities become other-than-temporary, the cost basis of the investment will be reduced and the resulting loss will be recognized in net income in the period the other-than-temporary impairment is identified, while any noncredit loss will be recognized in other comprehensive income. The amortized cost and estimated fair value of debt securities at March 31, 2018 , by contractual maturity, are shown in the following table (in thousands). Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties. Mortgage-backed securities have been allocated to their respective maturity groupings based on their contractual maturity.

Additionally, $2.7 million , net of deferred taxes, was reclassified from other comprehensive income to retained earnings on the consolidated balance sheets to recognize the prior period fair value impact of these securities. During the three months ended March 31, 2017 the Company realized $4.3 million of investment gains. These gains represented partial recoveries of impairment charges previously recognized on pooled trust preferred securities. As a result of these sales, the Company no longer holds any pooled trust preferred securities in its investment portfolio. The carrying value of securities pledged to secure public deposits and for other purposes as required or permitted by law approximated $448 million and $429 million at March 31, 2018 and December 31, 2017 , respectively.

Construction loans of $30.9 million and $28.9 million are included within commercial real estate loans at March 31, 2018 and December 31, 2017 , respectively. The Company’s commercial and residential real estate construction loans are primarily secured by real estate within the Company’s principal markets. These loans were originated under the Company’s loan policy, which is focused on the risk characteristics of residential and commercial real estate lending, including specific risks related to construction lending. Adequate consideration has been given to these loans in establishing the Company’s allowance for loan losses.

Receivables [Abstract]
Allowance For Loan Losses	Allowance For Loan Losses Management systematically monitors the loan portfolio and the adequacy of the allowance for loan losses on a quarterly basis to provide for probable losses inherent in the portfolio. Management assesses the risk in each loan type based on historical trends, the general economic environment of its local markets, individual loan performance and other relevant factors. Individual credits are selected throughout the year for detailed loan reviews, which are utilized by management to assess the risk in the portfolio and the adequacy of the allowance. Due to the nature of commercial lending, evaluation of the adequacy of the allowance as it relates to these loan types is often based more upon specific credit reviews, with consideration given to the potential impairment of certain credits and historical loss rates, adjusted for economic conditions and other inherent risk factors. The following table summarizes the activity in the allowance for loan loss, by portfolio loan classification, for the three months ended March 31, 2018 and 2017 (in thousands). The allocation of a portion of the allowance in one portfolio segment does not preclude its availability to absorb losses in other portfolio segments. The following table also presents the balance in the allowance for loan loss disaggregated on the basis of the Company’s impairment measurement method and the related recorded investment in loans, by portfolio segment, as of March 31, 2018 and December 31, 2017 (in thousands).

All non-commercial loans are evaluated based on payment history. The Company’s internal risk ratings for commercial loans are: Pass, Special Mention, Substandard and Doubtful. Each internal risk rating is defined in the loan policy using the following criteria: balance sheet yields; ratios and leverage; cash flow spread and coverage; prior history; capability of management; market position/industry; potential impact of changing economic, legal, regulatory or environmental conditions; purpose; structure; collateral support; and guarantor support. Risk grades are generally assigned by the primary lending officer and are periodically evaluated by the Company’s internal loan review process. Based on an individual loan’s risk grade, estimated loss percentages are applied to the outstanding balance of the loan to determine the amount of probable loss. The Company categorizes loans into risk categories based on relevant information regarding the customer’s debt service ability, capacity, overall collateral position along with other economic trends, and historical payment performance. The risk grades for each credit are updated when the Company receives current financial information, the loan is reviewed by the Company’s internal loan review and credit administration departments, or the loan becomes delinquent or impaired. The risk grades are updated a minimum of annually for loans rated exceptional, good, acceptable, or pass/watch. Loans rated special mention, substandard or doubtful are reviewed at least quarterly. The Company uses the following definitions for its risk ratings: Risk Rating Description Pass ratings: (a) Exceptional Loans classified as exceptional are secured with liquid collateral conforming to the internal loan policy. Loans rated within this category pose minimal risk of loss to the bank. (b) Good Loans classified as good have similar characteristics that include a strong balance sheet, satisfactory debt service coverage ratios, strong management and/or guarantors, and little exposure to economic cycles. Loans in this category generally have a low chance of loss to the bank. (c) Acceptable Loans classified as acceptable have acceptable liquidity levels, adequate debt service coverage ratios, experienced management, and have average exposure to economic cycles. Loans within this category generally have a low risk of loss to the bank. (d) Pass/watch Loans classified as pass/watch have erratic levels of leverage and/or liquidity, cash flow is volatile and the borrower is subject to moderate economic risk. A borrower in this category poses a low to moderate risk of loss to the bank. Special mention Loans classified as special mention have a potential weakness(es) that deserves management’s close attention. The potential weakness could result in deterioration of the loan repayment or the bank’s credit position at some future date. A loan rated in this category poses a moderate loss risk to the bank. Substandard Loans classified as substandard reflect a customer with a well defined weakness that jeopardizes the liquidation of the debt. Loans in this category have the possibility that the bank will sustain some loss if the deficiencies are not corrected and the bank’s collateral value is weakened by the financial deterioration of the borrower. Doubtful Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristics that make collection of the full contract amount highly improbable. Loans rated in this category are most likely to cause the bank to have a loss due to a collateral shortfall or a negative capital position.

Loan origination fees, and certain direct costs, are deferred and amortized as an adjustment to the yield over the term of the loan. The accrual of interest generally is discontinued when a loan becomes 90 days past due as to principal or interest for all loan types. However, any loan may be placed on non-accrual status if the Company receives information that indicates a borrower is unable to meet the contractual terms of its respective loan agreement. Other indicators considered for placing a loan on non-accrual status include the borrower’s involvement in bankruptcies, foreclosures, repossessions, litigation and any other situation resulting in doubt as to whether full collection of contractual principal and interest is attainable. When interest accruals are discontinued, unpaid interest recognized in income in the current year is reversed, and interest accrued in prior years is charged to the allowance for loan losses. Management may elect to continue the accrual of interest when the net realizable value of collateral exceeds the principal balance and related accrued interest, and the loan is in the process of collection. Generally for all loan classes, interest income during the period the loan is non-performing is recorded on a cash basis after recovery of principal is reasonably assured. Cash payments received on nonperforming loans are typically applied directly against the outstanding principal balance until the loan is fully repaid. Generally, loans are restored to accrual status when the obligation is brought current, the borrower has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Generally, all loan types are considered past due when the contractual terms of a loan are not met and the borrower is 30 days or more past due on a payment. Furthermore, residential and home equity loans are generally subject to charge-off when the loan becomes 120 days past due, depending on the estimated fair value of the collateral less cost to dispose, versus the outstanding loan balance. Commercial loans are generally charged off when the loan becomes 120 days past due. Open-end consumer loans are generally charged off when the loan becomes 180 days past due.

There were no commitments to provide additional funds on non-accrual, impaired or other potential problem loans at March 31, 2018 . Loan Modifications The Company’s policy on loan modifications typically does not allow for modifications that would be considered a concession from the Company. However, when there is a modification, the Company evaluates each modification to determine if the modification constitutes a troubled debt restructuring (“TDR”) in accordance with ASU 2011-02, whereby a modification of a loan would be considered a TDR when both of the following conditions are met: (1) a borrower is experiencing financial difficulty and (2) the modification constitutes a concession. When determining whether the borrower is experiencing financial difficulties, the Company reviews whether the borrower is currently in payment default on any of its debt or whether it is probable that the borrower would be in payment default in the foreseeable future without the modification. Other indicators of financial difficulty include whether the borrower has declared or is in the process of declaring bankruptcy, the borrower’s ability to continue as a going concern, and the borrower’s projected cash flow to service its debt (including principal and interest) in accordance with the contractual terms for the foreseeable future, without a modification. Regulatory guidance requires loans to be accounted for as collateral-dependent loans when borrowers have filed Chapter 7 bankruptcy, the debt has been discharged by the bankruptcy court, and the borrower has not reaffirmed the debt. The filing of bankruptcy is deemed to be evidence that the borrower is in financial difficulty and the discharge of the debt by the bankruptcy court is deemed to be a concession granted to the borrower.

Long-Term Debt	Long-Term Debt The components of long-term debt are summarized below (in thousands): March 31, 2018 December 31, 2017 Junior subordinated debentures owed to City Holding Capital Trust III, due 2038, interest at a rate of 5.62% and 5.09%, respectively $ 16,495 $ 16,495 The Company formed a statutory business trust, City Holding Capital Trust III (“Capital Trust III”), under the laws of Delaware. Capital Trust III was created for the exclusive purpose of (i) issuing trust-preferred capital securities (“Capital Securities”), which represent preferred undivided beneficial interests in the assets of the trust, (ii) using the proceeds from the sale of the Capital Securities to acquire junior subordinated debentures (“Debentures”) issued by the Company, and (iii) engaging in only those activities necessary or incidental thereto. The trust is considered a variable interest entity for which the Company is not the primary beneficiary. Accordingly, the accounts of the trust are not included in the Company’s consolidated financial statements. Distributions on the Debentures are cumulative and will be payable quarterly at an interest rate of 3.50% over the three month LIBOR rate, reset quarterly. Interest payments are due in March, June, September and December each year until maturity. The Debentures are redeemable prior to maturity at the option of the Company (i) in whole at any time or in part from time to time, or (ii) in whole, but not in part, at any time within 90 days following the occurrence and during the continuation of certain predefined events. Payments of distributions on the Capital Securities and payments on redemption of the Capital Securities are guaranteed by the Company. The Company also entered into an agreement as to expenses and liabilities with the trust pursuant to which it agreed, on a subordinated basis, to pay any cost, expenses or liabilities of the trust other than those arising under the Capital Securities. The obligations of the Company under the Debentures, the related indentures, the trust agreement establishing the trust, the guarantees and the agreements as to expenses and liabilities, in the aggregate, constitute a full and unconditional guarantee by the Company of the trust’s obligations under the Capital Securities. The Capital Securities issued by the statutory business trust qualify as Tier 1 capital for the Company under current Federal Reserve Board guidelines.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company enters into derivative transactions principally to protect against the risk of adverse price or interest rate movements on the value of certain assets and liabilities on future cash flows. As of March 31, 2018 and December 31, 2017 , the Company has derivative financial instruments not included in hedge relationships. These derivatives consist of interest rate swaps and floors used for interest rate management purposes and derivatives executed with commercial banking customers to facilitate their interest rate management strategies. For the majority of these instruments the Company acts as an intermediary for its customers. Changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Company's results of operations. The Company also has an interest rate swap that serves as a fair value hedge for changes in long term fixed interest rates related to commercial real estate loans. Hedge ineffectiveness is assessed quarterly and any ineffectiveness is recorded as non-interest expense. For the three months ended March 31, 2018 and 2017 , hedge ineffectiveness was less than $0.1 million and the change in fair value was less than $0.1 million , for each respective period. The following table summarizes the notional and fair value of these derivative instruments (in thousands): March 31, 2018 December 31, 2017 Notional Amount Fair Value Notional Amount Fair Value Non-hedging interest rate derivatives: Customer counterparties: Loan interest rate swap - assets $ 86,856 $ 2,039 $ 225,480 $ 4,877 Loan interest rate swap - liabilities 426,241 19,452 314,450 9,513 Financial institution counterparties: Loan interest rate swap - assets 432,755 19,620 320,949 9,591 Loan interest rate swap - liabilities 86,856 2,039 218,924 4,877 Derivatives designated as hedges of fair value: Financial institution counterparties: Loan interest rate swap - assets 3,961 93 4,326 34 The following table summarizes the change in fair value of these derivative instruments (in thousands): Three months ended March 31, 2018 2017 Change in fair value non-hedging interest rate derivatives: Other expense $ 90 $ 45 Change in fair value hedging interest rate derivatives: Other expense 1 (4 ) Certain financial instruments, including derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements. The Company's derivative transactions with financial institution counterparties are generally executed under International Swaps and Derivative Association ("ISDA") master agreements which include "right of setoff" provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Company does not generally offset financial instruments for financial reporting purposes. Information about financial instruments that are eligible for offset in the consolidated balance sheet as of March 31, 2018 is presented in the following tables (in thousands): Gross Amounts Not Offset in the Balance Sheet Total of Gross Amounts Not Offset in the Statement of Financial Position Netting Including Gross Net Amounts Adjustment Applicable Amounts of Assets per Netting Gross Offset in the Presented in Applicable Agreement Amounts of Statement of the Statement Master Fair Value and Fair Recognized Financial of Financial Netting of Financial Value of Description Assets Position Position Arrangements Collateral Collateral Net Amount (a) (b) (c)=(a)-(b) (d) (c)-(d) * Non-hedging derivative assets: Interest rate swap agreements - customer counterparties $ 2,039 $ — $ 2,039 $ — $ 2,039 $ 2,039 $ — Interest rate swap agreements - financial institution counterparties $ 19,620 $ — $ 19,620 $ — $ — $ — $ 19,620 Hedging derivative assets: Interest rate swap agreements - financial institution counterparties $ 93 $ — $ 93 $ — $ 70 $ 70 $ 23 Non-hedging derivative liabilities: Interest rate swap agreements - customer counterparties $ 19,452 $ — $ 19,452 $ — $ 19,452 $ 19,452 $ — Interest rate swap agreements - financial institution counterparties $ 2,039 $ — $ 2,039 $ — $ 14,671 $ 14,671 $ — * For instances where the fair value of financial collateral meets or exceeds the amounts presented in the Consolidated Balance Sheets, no value is displayed to represent full collateralization.

Share-based Compensation [Abstract]
Employee Benefit Plans	Employee Benefit Plans Pursuant to the terms of the City Holding Company 2003 Incentive Plan and the City Holding Company 2013 Incentive Plan (the "2003 Plan” and "2013 Plan", respectively), the Compensation Committee of the Board of Directors, or its delegate, may, from time to time, grant stock options, stock appreciation rights (“SARs”), or restricted stock awards to employees, directors and individuals who provide service to the Company (collectively, "Plan Participants"). The 2003 Plan expired in April of 2013 and the 2013 Plan was approved by the Company's shareholders in April 2013. A maximum of 750,000 shares of the Company’s common stock may be issued upon the exercise of stock options, SARs and stock awards under the 2013 Plan. These limitations may be adjusted in the event of a change in the number of outstanding shares of common stock by reason of a stock dividend, stock split or other similar event. Specific terms of options and SARs awarded, including vesting periods, exercise prices (stock price at date of grant) and expiration dates are determined at the date of grant and are evidenced by agreements between the Company and the awardee. The exercise price of the option grants equals the market price of the Company’s common stock on the date of grant. All incentive stock options and SARs will be exercisable up to 10 years from the date granted and all options and SARs are exercisable for the period specified in the individual agreement. As of March 31, 2018 , approximately 541,000 shares were still available to be issued under the 2013 Plan. Each award from the 2003 Plan and 2013 Plan is evidenced by an award agreement that specifies the option price, the duration of the option, the number of shares to which the option pertains, and such other provisions as the Compensation Committee, or its delegate, determines. The option price for each grant is equal to the fair market value of a share of the Company’s common stock on the date of the grant. Options granted expire at such time as the Compensation Committee, or its delegate, determines at the date of the grant and in no event does the exercise period exceed a maximum of ten years. Upon a change-in-control of the Company, as defined in the 2003 Plan and 2013 Plan, all outstanding options and awards shall immediately vest. Certain stock options and restricted stock awards granted pursuant to the 2013 Plan have performance-based vesting requirements. These shares will vest in three separate annual installments of approximately 33.33% per installment on the third, fourth and fifth anniversaries of the grant date, subject further to performance-based vesting requirements. To meet the performance-based vesting requirement, the Company's mean return on average assets of the three, four and five year period prior to the respective vesting date must meet or exceed the median return on average assets over the 20 year period immediately preceding the vesting date of all FDIC insured depository institutions. The mean return on average assets excludes merger and acquisition expenses and other nonrecurring items as determined by the Board of Directors of the Company. In 2018, the Board of Directors granted the named executive officers ("NEOs") restricted stock units ("RSUs") and performance share units ("PSUs"). The RSUs will vest in three separate annual installments of approximately 33.33% per installment on the first, second and third anniversaries of the grant date, subject to a two-year holding period. The PSUs will vest on the third anniversary of the grant date. The payout for the PSUs will be determined based on (1) the Company's three-year relative average return on assets ("ROA") during the three-year performance period relative to the ROA for the selected peer companies and (2) the Company's total shareholder return ("TSR") relative to the TSR of the selected peer companies during the three-year performance period. If the three-year relative ROA is at or below the 25th percentile, 0% of the PSU grant will be earned; at the 50th percentile, 100% of the PSU grant will be earned; or at the 100th percentile, 200% of the PSU grant will be earned. The payout of the PSUs will be increased or decreased as determined by a modifier based on the Company's TSR. If the three-year relative TSR is at or below the 25th percentile, the number of PSUs granted will be reduced by 25%; at the 50th percentile, the number of PSUs granted will not be adjusted; or at or above the 75th percentile, the number of PSUs granted will be increased by 25%.

The restricted shares awarded become fully vested after various periods of continued employment from the respective dates of grant. The Company is entitled to an income tax deduction in an amount equal to the taxable income reported by the holders of the restricted shares when the restrictions are released and the shares are issued. Compensation is being charged to expense over the respective vesting periods. Restricted shares are forfeited if the awardee officer or employee terminates his employment with the Company prior to the lapsing of restrictions. The Company records forfeitures of restricted stock as treasury share repurchases and any compensation cost previously recognized is reversed in the period of forfeiture. Recipients of restricted shares do not pay any cash consideration to the Company for the shares, and have the right to vote all shares subject to such grant and receive all dividends with respect to such shares, whether or not the shares have vested. For restricted shares that have performance-based criteria, management has evaluated those criteria and has determined that, as of March 31, 2018 , the criteria were probable of being met.

Benefit Plans The Company provides retirement benefits to its employees through the City Holding Company 401(k) Plan and Trust (the “401(k) Plan”), which is intended to be compliant with Employee Retirement Income Security Act (ERISA) section 404(c). The Company also maintains two frozen defined benefit pension plans (the “Defined Benefit Plans”), which were inherited from the Company's acquisition of the plan sponsors (Horizon Bancorp, Inc. and Community Financial Corporation). During 2017, the Company initiated the process to terminate the Community Defined Benefit plan. The Company anticipates making a $1.6 million contribution in late 2018 or early 2019 (which has been accrued at March 31, 2018), when the termination process is expected to be completed.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is a party to certain financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The Company has entered into agreements with certain customers to extend credit or provide a conditional commitment to provide payment on drafts presented in accordance with the terms of the underlying credit documents. The Company also provides overdraft protection to certain demand deposit customers that represent an unfunded commitment. Overdraft protection commitments, which are included with other commitments below, are uncollateralized and are paid at the Company’s discretion. Conditional commitments generally include standby and commercial letters of credit. Standby letters of credit represent an obligation of the Company to a designated third party contingent upon the failure of a customer of the Company to perform under the terms of the underlying contract between the customer and the third party. Commercial letters of credit are issued specifically to facilitate trade or commerce. Under the terms of a commercial letter of credit, drafts will be drawn when the underlying transaction is consummated, as intended, between the customer and a third party. The funded portion of these financial instruments is reflected in the Company’s balance sheet, while the unfunded portion of these commitments is not reflected in the balance sheet. The table below presents a summary of the contractual obligations of the Company resulting from significant commitments (in thousands): March 31, 2018 December 31, 2017 Commitments to extend credit: Home equity lines $ 196,946 $ 194,477 Commercial real estate 45,832 66,901 Other commitments 159,622 184,895 Standby letters of credit 7,098 7,151 Commercial letters of credit 863 831 Loan commitments and standby and commercial letters of credit have credit risks essentially the same as those involved in extending loans to customers and are subject to the Company’s standard credit policies. Collateral is obtained based on management’s credit assessment of the customer. Management does not anticipate any material losses as a result of these commitments. The Company is engaged in various legal actions that it deems to be in the ordinary course of business. As these legal actions are resolved, the Company could realize positive and/or negative impact to its financial performance in the period in which these legal actions are ultimately resolved. There can be no assurance that current legal actions will have an immaterial impact on financial results, either positive or negative, or that no material legal actions may be presented in the future.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Company has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company bases fair value of assets and liabilities on quoted market prices, prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. If such information is not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amount presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Financial Assets and Liabilities The Company used the following methods and significant assumptions to estimate fair value for financial assets and liabilities measured on a recurring basis. Securities Available for Sale . Securities available for sale are reported at fair value utilizing Level 1, Level 2, and Level 3 inputs. The fair value of securities available for sale is determined by utilizing a market approach by obtaining quoted prices on nationally recognized securities exchanges (other than forced or distressed transactions) that occur in sufficient volume or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities. If such measurements are unavailable, the security is classified as Level 3. Significant judgment is required to make this determination. The Company utilizes a third party pricing service provider to value its Level 1 and Level 2 investment securities. Annually, the Company obtains an independent auditor’s report from its third party pricing service provider regarding its controls over investment securities. Although no control deficiencies were noted, the report did contain caveats and disclaimers regarding the pricing information, such as the Company should review fair values for reasonableness. On a quarterly basis, the Company selects a sample of its debt securities and reprices those securities with a third party that is independent of the primary pricing service provider to verify the reasonableness of the fair values. In addition, the Company selects a sample of securities and reviews the underlying support from the primary pricing service provider. Derivatives . Derivatives are reported at fair value utilizing Level 2 inputs. The Company utilizes a market approach by obtaining dealer quotations to value its customer interest rate swaps. The Company’s derivatives are included within its Other Assets and Other Liabilities in the accompanying consolidated balance sheets. Derivative assets are typically secured through securities with financial counterparties or cross collateralization with a borrowing customer. Derivative liabilities are typically secured through the Company pledging securities to financial counterparties or, in the case of a borrowing customer, by the right of setoff. The Company considers factors such as the likelihood of default by itself and its counterparties, right of setoff, and remaining maturities in determining the appropriate fair value adjustments. All derivative counterparties approved by the Company's Asset and Liability Committee ("ALCO") are regularly reviewed, and appropriate business action is taken to adjust the exposure to certain counterparties, if necessary. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of marketable collateral securing the position. This approach used to estimate impacted exposures to counterparties is also used by the Company to estimate its own credit risk in derivative liability positions. To date, no material losses have been incurred due to a counterparty's inability to pay any undercollateralized position. There was no significant change in the value of derivative assets and liabilities attributed to credit risk that would have resulted in a derivative credit risk valuation adjustment at March 31, 2018 . The Company may be required, from time to time, to measure certain financial assets and financial liabilities at fair value on a nonrecurring basis. Financial assets measured at fair value on a nonrecurring basis include impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data for real estate collateral or Level 3 inputs for non-real estate collateral. The following table presents assets and liabilities measured at fair value (in thousands): Total Level 1 Level 2 Level 3 Total Gains (Losses) March 31, 2018 Recurring fair value measurements Financial Assets U.S. Government agencies $ 1 $ — $ 1 $ — Obligations of states and political subdivisions 94,173 — 94,173 — Mortgage-backed securities: U.S. Government agencies 427,394 — 427,394 — Private label 602 — 602 — Trust preferred securities 4,793 — 4,532 261 Corporate securities 17,200 — 17,200 — Marketable equity securities 10,584 10,584 — — Investment funds 1,465 1,465 — — Derivative assets 21,752 — 21,752 — Financial Liabilities Derivative liabilities 21,491 — 21,491 — Nonrecurring fair value measurements Financial Assets Impaired loans $ 9,434 $ — $ — $ 9,434 $ (172 ) Non-Financial Assets Other real estate owned 3,912 — — 3,912 (225 ) December 31, 2017 Recurring fair value measurements Financial Assets U.S. Government agencies $ 2 $ — $ 2 $ — Obligations of states and political subdivisions 96,196 — 96,196 — Mortgage-backed securities: U.S. Government agencies 419,347 — 419,347 — Private label 652 — 652 — Trust preferred securities 4,736 — 4,475 261 Corporate securities 22,268 — 22,268 — Marketable equity securities 5,699 5,699 — — Investment funds 1,489 1,489 — — Derivative assets 14,502 — 14,502 — Financial Liabilities Derivative liabilities 14,390 — 14,390 — Nonrecurring fair value measurements Financial Assets Impaired loans $ 9,020 $ — $ — $ 9,020 $ (647 ) Non-Financial Assets Other real estate owned 3,585 — — 3,585 (374 ) Other assets — — — — (170 ) The table below presents a reconcilement of the Company’s financial assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3), which consist solely of trust preferred securities (in thousands): Three months ended March 31, 2018 2017 Beginning balance $ 261 $ 2,535 Included in other comprehensive income — (977 ) Dispositions — (1,300 ) Transfers into Level 3 — — Ending balance $ 261 $ 258 The Company utilizes a third party model to compute the present value of expected cash flows which considers the structure and term of pooled trust preferred securities and the financial condition of the underlying issuers. Specifically, the third party model details interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes. The current estimate of expected cash flows is based on the most recent trustee reports and any other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred securities. For issuing banks that have defaulted, management generally assumes no recovery. For issuing banks that have deferred interest payments, management excludes the collateral balance associated with these banks and assumes no recoveries of such collateral balance in the future. The exclusion of such issuing banks in a current deferral position is based on such bank experiencing a certain level of financial difficulty that raises doubt about its ability to satisfy its contractual debt obligation, and accordingly, the Company excludes the associated collateral balance from its estimate of expected cash flows. Other assumptions used in the estimate of expected cash flows include expected future default rates and prepayments. The table below presents a reconcilement of the Company's financial assets and liabilities measured at fair value on a nonrecurring basis using significant unobservable inputs (Level 3), which solely relates to impaired loans that were remeasured and reported at fair value through a specific valuation allowance allocation of the allowance for loan losses based upon the fair value of the underlying collateral (in thousands). The fair value of impaired loans is estimated using one of several methods, including collateral value, liquidation value and discounted cash flows. The significant unobservable inputs used in the fair value measurement of collateral for collateral-dependent impaired loans primarily relate to discounts applied to the customers’ reported amount of collateral. The amount of collateral discount depends upon the marketability of the underlying collateral. During the three months ended March 31, 2018 and 2017 , collateral discounts ranged from 20% to 30% . During the three months ended March 31, 2018 and 2017 , the Company had no Level 2 financial assets and liabilities that were measured on a nonrecurring basis.

Certain non-financial assets measured at fair value on a non-recurring basis include other real estate owned (“OREO”), which is measured at the lower of cost or fair value, and goodwill and other intangible assets, which are measured at fair value for impairment assessments. The table below presents OREO that was remeasured and reported at fair value based on significant unobservable inputs (Level 3) (in thousands): Three months ended March 31, 2018 2017 Beginning balance $ 3,585 $ 4,588 OREO remeasured at initial recognition: Carrying value of foreclosed assets prior to remeasurement 1,218 1,226 Charge-offs recognized in the allowance for loan losses (353 ) (442 ) Fair value 865 784 OREO remeasured subsequent to initial recognition: Carrying value of foreclosed assets prior to remeasurement 1,362 1,464 Fair value 1,137 1,273 Write-downs included in other non-interest expense (225 ) (191 ) Disposed (313 ) (776 ) Ending balance $ 3,912 $ 4,405 ASC Topic 825 “Financial Instruments” , as amended, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including discount rates and estimate of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. ASC Topic 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The following methods and assumptions were used in estimating fair value for financial instruments: Cash and cash equivalents: Due to their short-term nature, the carrying amounts reported in the consolidated balance sheets approximate fair value. Securities: The fair value of securities, both available-for-sale and held-to-maturity, are generally based on quoted market prices or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities. Net loans: The fair value of the loan portfolio is estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made to borrowers for the same remaining maturities, the credit risk associated with such loans and other market factors, including liquidity. Loans were first segregated by type such as commercial, real estate and consumer, and were then further segmented into fixed, adjustable and variable rate categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Deposits: The fair values of demand deposits (i.e., interest and noninterest-bearing deposits, regular savings and other money market demand accounts) are, by definition, equal to their carrying values. The fair values of time deposits were estimated using discounted cash flow analyses. The discount rates used were based on rates currently offered for deposits with similar remaining maturities. The fair values of the time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Short-term debt: Securities sold under agreements to repurchase represent borrowings with original maturities of less than 90 days. The carrying amount of borrowings under purchase agreements approximate their fair value. Long-term debt: The fair value of long-term borrowings is estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements and market conditions of similar debt instruments. Commitments and letters of credit: The fair values of commitments are estimated based on fees currently charged to enter into similar agreements, taking into consideration the remaining terms of the agreements and the counterparties’ credit standing. The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. The amounts of fees currently charged on commitments and letters of credit are deemed insignificant, and therefore, the estimated fair values and carrying values have not been reflected in the table below. The following table represents the estimates of fair value of financial instruments (in thousands). This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as noninterest-bearing demand, interest-bearing demand and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.

Revenue from Contracts with Customer [Abstract]
Contracts with Customers	Note M – Contracts with Customers The Company's largest source of revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASC Topic 606, Revenue from Contracts with Customers ("ASC 606"), and non-interest income. The Company's significant sources of non-interest income are: service charges, bankcard revenue, trust and investment management fee income and bank owned life insurance (which was also excluded from the ASC 606). The following table shows the Company's total non-interest income segregated between those within the scope of ASC 606 and those with the scope of other GAAP Topics (in thousands): Three months ended March 31, 2018 Non-interest income Non-interest income from contracts with customers $ 13,465 Non-interest income within the scope of other GAAP topics 1,027 Total non-interest income $ 14,492 The Company's significant policies related to contracts with customers are discussed below. Service Charges: Service charges consist of service charges on deposit accounts (monthly service fees, account analysis fees, non-sufficient funds ("NSF") fees and other deposit account related fees). For transaction based fees, the Company's performance obligation is generally satisfied, and the related revenue recognized, at a point in time. For nontransaction based fees, the Company's performance obligation is generally satisfied, and the related revenue recognized, over the period in which the service is provided (typically a month). Generally, payments are received immediately through a direct charge to the customer's account. Bankcard Revenue: Bankcard revenue is primarily comprised of debit card income and ATM fees. Debit card income is primarily comprised of interchange fees earned whenever the Company's debit cards are processed through card payment networks such as Mastercard. ATM fees are primarily generated when a non-Company cardholder uses a Company ATM or when a Company cardholder uses a non-Company ATM. The Company's performance obligation for bankcard revenue is generally satisfied, and the related revenue recognized, when the services are rendered. Generally, payments are received immediately or in the following month. Trust and Investment Management Fee Income: Trust and investment management fee income is primarily comprised of fees earned from the management and administration of customer assets. The Company's performance obligation is generally satisfied over time (typically a quarter), and the related revenue recognized, based upon the quarter-end market value of the assets under management and the applicable fee rate. Generally, payments are received a few days after quarter-end through a direct charge to the customer's account. The following table illustrates the disaggregation by the Company's major revenue streams (in thousands): Point of Revenue Three months ended Recognition March 31, 2018 Major revenue streams Service charges At a point in time & over time $ 6,862 Bankcard revenue At a point in time 4,334 Trust and investment management fee income Over time 1,568 Other income At a point in time & over time 701 Net revenue from contracts with customers 13,465 Non-interest income within the scope of other GAAP topics 1,027 Total non-interest income $ 14,492

Schedule Of Credit Quality Indicators	The Company uses the following definitions for its risk ratings: Risk Rating Description Pass ratings: (a) Exceptional Loans classified as exceptional are secured with liquid collateral conforming to the internal loan policy. Loans rated within this category pose minimal risk of loss to the bank. (b) Good Loans classified as good have similar characteristics that include a strong balance sheet, satisfactory debt service coverage ratios, strong management and/or guarantors, and little exposure to economic cycles. Loans in this category generally have a low chance of loss to the bank. (c) Acceptable Loans classified as acceptable have acceptable liquidity levels, adequate debt service coverage ratios, experienced management, and have average exposure to economic cycles. Loans within this category generally have a low risk of loss to the bank. (d) Pass/watch Loans classified as pass/watch have erratic levels of leverage and/or liquidity, cash flow is volatile and the borrower is subject to moderate economic risk. A borrower in this category poses a low to moderate risk of loss to the bank. Special mention Loans classified as special mention have a potential weakness(es) that deserves management’s close attention. The potential weakness could result in deterioration of the loan repayment or the bank’s credit position at some future date. A loan rated in this category poses a moderate loss risk to the bank. Substandard Loans classified as substandard reflect a customer with a well defined weakness that jeopardizes the liquidation of the debt. Loans in this category have the possibility that the bank will sustain some loss if the deficiencies are not corrected and the bank’s collateral value is weakened by the financial deterioration of the borrower. Doubtful Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristics that make collection of the full contract amount highly improbable. Loans rated in this category are most likely to cause the bank to have a loss due to a collateral shortfall or a negative capital position.

The fair value of impaired loans is estimated using one of several methods, including collateral value, liquidation value and discounted cash flows. The significant unobservable inputs used in the fair value measurement of collateral for collateral-dependent impaired loans primarily relate to discounts applied to the customers’ reported amount of collateral. The amount of collateral discount depends upon the marketability of the underlying collateral. During the three months ended March 31, 2018 and 2017 , collateral discounts ranged from 20% to 30% . During the three months ended March 31, 2018 and 2017 , the Company had no Level 2 financial assets and liabilities that were measured on a nonrecurring basis.

Schedule Of Estimates Of Fair Value Of Financial Instruments	The following table represents the estimates of fair value of financial instruments (in thousands). This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as noninterest-bearing demand, interest-bearing demand and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.
