Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying consolidated financial statements have been prepared pursuant to rules and regulations of the SEC and in compliance with accounting principles generally accepted in the United States of America (“GAAP”). Because this report is based on an interim period, certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. In the opinion of management of the registrant, the accompanying consolidated financial statements as of June 30, 2019 and for the three and six month 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 for the periods presented. The financial performance reported for CNB Financial Corporation (the “Corporation”) for the three and 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 Corporation’s Annual Report on Form 10-K for the period ended December 31, 2018 (the “ 2018 Form 10-K”). All dollar amounts are stated in thousands, except share and per share data and other amounts as indicated. Certain prior period amounts have been reclassified to conform to the current period presentation.

Stock Compensation

Stock Compensation	6 Months Ended

Share-based Payment Arrangement [Abstract]
Stock Compensation	STOCK COMPENSATION The Corporation has a stock incentive plan, which is administered by a committee of the Board of Directors and which permits the Corporation to provide various types of stock-based compensation to its key employees, directors, and/or consultants, including time-based and performance-based shares of restricted stock. The Corporation previously maintained the CNB Financial Corporation 2009 Stock Incentive Plan, which terminated in accordance with its terms on February 10, 2019, and currently maintains the CNB Financial Corporation 2019 Omnibus Incentive Plan (the "2019 Stock Incentive Plan"), which was approved by the Corporation’s shareholders and became effective on April 16, 2019. For key employees, the vesting of time-based restricted stock is one-third, one-fourth, or one-fifth of the granted restricted shares per year, beginning one year after the grant date, with 100% vesting on the third, fourth or fifth anniversary of the grant date, respectively. Prior to 2018, for non-employee directors, the vesting schedule was one-third of the granted restricted shares per year, beginning one year after the grant date, with 100% vested on the third anniversary of the grant date. Beginning in 2018, stock compensation received by non-employee directors vests immediately. At June 30, 2019 , there was no unrecognized compensation cost related to stock-based compensation awarded under this plan and, except for the time-based and performance-based restricted stock awards disclosed below and in previous filings, no other stock-based compensation was granted during the three or six month periods ended June 30, 2019 and 2018 . In addition to the time-based restricted stock disclosed above, the Corporation’s Board of Directors grants performance-based restricted stock awards (“PBRSAs”) to key employees. The number of PBRSAs will depend on certain performance conditions and are also subject to service-based vesting. In 2019, awards with a maximum of 16,681 shares in aggregate were granted to key employees. In 2018, awards with a maximum of 15,657 shares in aggregate were granted to key employees. In 2017, an award with a maximum of 7,109 shares was granted to a key employee. Compensation expense for the restricted stock awards is recognized over the requisite service period noted above based on the fair value of the shares at the date of grant. Nonvested restricted stock awards are recorded as a reduction of additional paid-in-capital in shareholders’ equity until earned. Compensation expense resulting from time-based, performance-based and director restricted stock awards was $275 and $867 for the three and six months ended June 30, 2019 and $272 and $949 for the three and six months ended June 30, 2018 . There was $911 and $775 of total unrecognized compensation cost related to unvested restricted stock awards, as of June 30, 2019 and December 31, 2018 , respectively. The total income tax benefit related to the recognized compensation cost of vested restricted stock awards was $58 and $182 for the three and six months ended June 30, 2019 and $57 and $199 for the three and six months ended June 30, 2018 , respectively. A summary of changes in time-based nonvested restricted stock awards for the three months ended June 30, 2019 follows: Shares Per Share Weighted Average Grant Date Fair Value Nonvested at beginning of period 67,769 $ 24.79 Vested (3,611 ) 23.42 Nonvested at end of period 64,158 $ 24.87 A summary of changes in time-based nonvested restricted stock awards for the six months ended June 30, 2019 follows: Shares Per Share Weighted Average Grant Date Fair Value Nonvested at beginning of period 75,889 $ 23.20 Granted 25,940 25.27 Vested (37,671 ) 21.76 Nonvested at end of period 64,158 $ 24.87 The above table excludes 13,850 shares in restricted stock awards that were granted at a weighted average fair value of $25.27 and immediately vested. Compensation expense resulting from the immediately vested shares was $0 and $350 for the three and six months ended June 30, 2019 and is included in the previously disclosed $275 and $867 above, respectively. The fair value of shares vested was $101 and $1,328 during the three and six months ended June 30, 2019 and $9 and $1,471 for the three and six months ended June 30, 2018 .

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE Fair Value Measurement Fair value is defined as the exchange price that would be received for an asset or paid to transfer a 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. A fair value hierarchy has also been established which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The following three levels of inputs are used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity 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; or 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 fair values of most trading securities and securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The Corporation’s derivative instruments are interest rate swaps that are similar to those that trade in liquid markets. As such, significant fair value inputs can generally be verified and do not typically involve significant management judgments (Level 2 inputs). The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals prepared by third-parties. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Management also adjusts appraised values based on the length of time that has passed since the appraisal date and other factors. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Assets and liabilities measured at fair value on a recurring basis are as follows at June 30, 2019 and December 31, 2018 : Fair Value Measurements at June 30, 2019 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Securities Available For Sale: U.S. Government sponsored entities $ 140,727 $ 0 $ 140,727 $ 0 States and political subdivisions 119,454 0 119,454 0 Residential and multi-family mortgage 233,064 0 233,064 0 Corporate notes and bonds 11,889 0 11,889 0 Pooled SBA 27,876 0 27,876 0 Other 960 960 0 0 Total Securities Available For Sale $ 533,970 $ 960 $ 533,010 $ 0 Interest Rate swaps $ 1,802 $ 0 $ 1,802 $ 0 Trading Securities: Corporate equity securities $ 7,155 $ 7,155 $ 0 $ 0 Mutual funds 916 916 0 0 Certificates of deposit 179 179 0 0 Corporate notes and bonds 603 603 0 0 U.S. Government sponsored entities 51 0 51 0 Total Trading Securities $ 8,904 $ 8,853 $ 51 $ 0 Liabilities: Interest rate swaps $ (2,328 ) $ 0 $ (2,328 ) $ 0 Fair Value Measurements at December 31, 2018 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Securities Available For Sale: U.S. Government sponsored entities $ 132,694 $ 0 $ 132,694 $ 0 States and political subdivisions 136,031 0 136,031 0 Residential and multi-family mortgage 206,053 0 206,053 0 Corporate notes and bonds 11,777 0 11,777 0 Pooled SBA 29,374 0 29,374 0 Other 934 934 0 0 Total Securities Available For Sale $ 516,863 $ 934 $ 515,929 $ 0 Interest Rate swaps $ 485 $ 0 $ 485 $ 0 Trading Securities: Corporate equity securities $ 5,828 $ 5,828 $ 0 $ 0 Mutual funds 1,058 1,058 0 0 Certificates of deposit 268 268 0 0 Corporate notes and bonds 581 581 0 0 U.S. Government sponsored entities 51 0 51 0 Total Trading Securities $ 7,786 $ 7,735 $ 51 $ 0 Liabilities: Interest rate swaps $ (686 ) $ 0 $ (686 ) $ 0 Assets and liabilities measured at fair value on a non-recurring basis are as follows at June 30, 2019 and December 31, 2018 : Fair Value Measurements at June 30, 2019 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Impaired loans: Commercial, industrial, and agricultural $ 631 0 0 $ 631 Commercial mortgages $ 933 0 0 $ 933 Fair Value Measurements at December 31, 2018 Using Quoted Prices in Significant Active Markets for Significant Other Unobservable Identical Assets Observable Inputs Inputs Description Total (Level 1) (Level 2) (Level 3) Assets: Impaired loans: Commercial, industrial, and agricultural $ 2,055 0 0 $ 2,055 Commercial mortgages $ 679 0 0 $ 679 The estimated fair values of impaired collateral dependent loans, such as commercial or residential mortgages, are determined primarily through third-party appraisals. When a collateral dependent loan, such as a commercial or residential mortgage loan, becomes impaired, a decision is made regarding whether an updated certified appraisal of the real estate is necessary. This decision is based on various considerations, including the age of the most recent appraisal, the loan-to-value ratio based on the original appraisal, and the condition of the property. Appraised values are discounted to arrive at the estimated selling price of the collateral and a further reduction for estimated costs to sell the property is applied, which results in an amount that is considered to be the estimated fair value. If a loan becomes impaired and the appraisal of related loan collateral is outdated, management applies an appropriate adjustment factor based on its experience with current valuations of similar collateral in determining the loan’s estimated fair value and resulting allowance for loan losses. Third-party appraisals are not customarily obtained in respect of unimpaired loans, unless in management’s view changes in circumstances warrant obtaining an updated appraisal.

At June 30, 2019 and December 31, 2018 , management performed an assessment for possible other-than-temporary impairment of the Corporation’s debt securities, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. Based on the results of the assessment, management believes impairment of these debt securities at June 30, 2019 and December 31, 2018 to be temporary. For the securities that comprise corporate notes and bonds and the securities that are issued by state and political subdivisions, management monitors publicly available financial information, such as filings with the Securities and Exchange Commission, in order to evaluate the securities for other-than-temporary impairment. For financial institution issuers, management monitors information from quarterly “call” report filings that are used to generate Uniform Bank Performance Reports. All other securities that were in an unrealized loss position at the balance sheet date were reviewed by management, and issuer-specific documents were reviewed as appropriate given the following considerations. When reviewing securities for other-than-temporary impairment, management considers the financial condition and near-term prospects of the issuer and whether downgrades by bond rating agencies have occurred. Management also considers the length of time and extent to which fair value has been less than cost, and whether management does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. As of June 30, 2019 and December 31, 2018 , management concluded that the securities described in the previous paragraph were not other-than-temporarily impaired for the following reasons: • There is no indication of any significant deterioration of the creditworthiness of the institutions that issued the securities. • All contractual interest payments on the securities have been received as scheduled, and no information has come to management’s attention through the processes previously described which would lead to a conclusion that future contractual payments will not be timely received. The Corporation does not intend to sell and it is not more likely than not that it will be required to sell the securities in an unrealized loss position before recovery of its amortized cost basis. On June 30, 2019 and December 31, 2018 , securities carried at $261,059 and $290,717 , respectively, were pledged to secure public deposits and for other purposes as provided by law. Information pertaining to security sales on available for sale securities is as follows: Proceeds Gross Gains Gross Losses Three months ended June 30, 2019 $ 0 $ 0 $ 0 Three months ended June 30, 2018 $ 0 $ 0 $ 0 Six months ended June 30, 2019 $ 11,403 $ 152 $ 4 Six months ended June 30, 2018 $ 0 $ 0 $ 0 The tax provision related to these net realized gains was $0 and $31 during the three and six months ended June 30, 2019 .

Receivables [Abstract]
Loans	LOANS Total net loans at June 30, 2019 and December 31, 2018 are summarized as follows: June 30, 2019 December 31, 2018 Commercial, industrial, and agricultural $ 993,629 $ 916,297 Commercial mortgages 750,334 697,776 Residential real estate 786,354 771,309 Consumer 89,331 86,035 Credit cards 7,284 7,623 Overdrafts 337 308 Less: unearned discount (4,911 ) (4,791 ) allowance for loan losses (21,437 ) (19,704 ) Loans, net $ 2,600,921 $ 2,454,853 At June 30, 2019 and December 31, 2018 , net unamortized loan fees of $3,374 and $3,175 , respectively, have been included in the carrying value of loans. The Corporation’s outstanding loans and related unfunded commitments are primarily concentrated within central and northwest Pennsylvania, central and northeast Ohio, and western New York. The Bank attempts to limit concentrations within specific industries by utilizing dollar limitations to single industries or customers, and by entering into participation agreements with third parties. Collateral requirements are established based on management’s assessment of the customer. The Corporation maintains lending policies to control the quality of the loan portfolio. These policies delegate the authority to extend loans under specific guidelines and underwriting standards. These policies are prepared by the Corporation’s management and reviewed and ratified annually by the Corporation’s Board of Directors. Pursuant to the Corporation’s lending policies, management considers a variety of factors when determining whether to extend credit to a customer, including loan-to-value ratios, FICO scores, quality of the borrower’s financial statements, and the ability to obtain personal guarantees. Commercial, industrial, and agricultural loans comprised 38% and 37% of the Corporation’s total loan portfolio at June 30, 2019 and December 31, 2018 , respectively. Commercial mortgage loans comprised 29% and 28% of the Corporation’s total loan portfolio at June 30, 2019 and December 31, 2018 , respectively. Management assigns a risk rating to all commercial loans at loan origination. The loan-to-value policy guidelines for commercial, industrial, and agricultural loans are generally a maximum of 80% of the value of business equipment, a maximum of 75% of the value of accounts receivable, and a maximum of 60% of the value of business inventory at loan origination. The loan-to-value policy guideline for commercial mortgage loans is generally a maximum of 85% of the appraised value of the real estate. Residential real estate loans comprised 30% and 31% of the Corporation’s total loan portfolio at June 30, 2019 and December 31, 2018 , respectively. The loan-to-value policy guidelines for residential real estate loans vary depending on the collateral position and the specific type of loan. Higher loan-to-value terms may be approved with the appropriate private mortgage insurance coverage. The Corporation also originates and prices loans for sale into the secondary market. Loans so originated are classified as loans held for sale and are excluded from residential real estate loans reported above. The rationale for these sales is to mitigate interest rate risk associated with holding lower rate, long-term residential mortgages in the loan portfolio and to generate fee revenue from sales and servicing the loan. The Corporation also offers a variety of unsecured and secured consumer loan and credit card products which represented less than 4% of the total loan portfolio at both June 30, 2019 and December 31, 2018 . Terms and collateral requirements vary depending on the size and nature of the loan.

The modification of the terms of such loans included either or both of the following: a reduction of the stated interest rate of the loan or an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk. The following table presents the number of loans, loan balances, and specific reserves for loans that have been restructured in a troubled debt restructuring as of June 30, 2019 and December 31, 2018 .

There were no loans modified as troubled debt restructurings for which there was a payment default within a twelve-month cycle following the modification during the period ended June 30, 2019 and June 30, 2018 . There were no principal balances were forgiven in connection with the loan restructurings. In order to determine whether a borrower is experiencing financial difficulty, the Corporation evaluates the probability that the borrower will default on any of its debt payments in the foreseeable future without a loan modification. This evaluation is performed using the Corporation’s internal underwriting policies. The Corporation has no further loan commitments to customers whose loans are classified as a troubled debt restructuring. Generally, nonperforming troubled debt restructurings are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time (generally six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt. Credit Quality Indicators The Corporation classifies commercial, industrial, and agricultural loans and commercial mortgage loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Corporation uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Corporation’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not rated as special mention, substandard, or doubtful are considered to be pass rated loans. All loans included in the following tables have been assigned a risk rating within 12 months of the balance sheet date.

For residential real estate, consumer, and credit card loan classes, the Corporation also evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. The following table presents the recorded investment in residential, consumer, and credit card loans based on payment activity as of June 30, 2019 and December 31, 2018 : June 30, 2019 December 31, 2018 Residential Real Estate Consumer Credit Cards Residential Real Estate Consumer Credit Cards Performing $ 781,335 $ 88,777 $ 7,263 $ 765,823 $ 85,322 $ 7,618 Nonperforming 5,019 554 21 5,486 713 5 Total $ 786,354 $ 89,331 $ 7,284 $ 771,309 $ 86,035 $ 7,623 The Corporation’s portfolio of residential real estate and consumer loans maintained within Holiday Financial Services Corporation (“Holiday”) are considered to be subprime loans.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is computed by dividing net income, excluding net earnings allocated to participating securities, by the weighted average number of shares outstanding during the applicable period, excluding outstanding participating securities. Diluted earnings per share is computed using the weighted average number of shares determined for the basic computation plus the dilutive effect of potential common shares issuable under certain stock compensation plans. For the three and six months ended June 30, 2019 and 2018 , there were no outstanding stock options to include in the diluted earnings per share calculations and the impact of performance based shares was immaterial. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The Corporation has determined that its outstanding unvested stock awards are participating securities. The computation of basic and diluted earnings per share is shown below: Three months ended June 30, Six months ended June 30, 2019 2018 2019 2018 Basic earnings per common share computation: Net income per consolidated statements of income $ 9,767 $ 8,441 $ 19,240 $ 15,538 Net earnings allocated to participating securities (40 ) (39 ) (78 ) (73 ) Net earnings allocated to common stock $ 9,727 $ 8,402 $ 19,162 $ 15,465 Distributed earnings allocated to common stock $ 2,580 $ 2,510 $ 5,160 $ 5,019 Undistributed earnings allocated to common stock 7,147 5,892 14,002 10,446 Net earnings allocated to common stock $ 9,727 $ 8,402 $ 19,162 $ 15,465 Weighted average common shares outstanding, including shares considered participating securities 15,230 15,286 15,230 15,279 Less: Average participating securities (62 ) (69 ) (62 ) (70 ) Weighted average shares 15,168 15,217 15,168 15,209 Basic earnings per common share $ 0.64 $ 0.55 $ 1.26 $ 1.02 Diluted earnings per common share computation: Net earnings allocated to common stock $ 9,727 $ 8,402 $ 19,162 $ 15,465 Weighted average common shares outstanding for basic earnings per common share 15,168 15,217 15,168 15,209 Add: Dilutive effects of assumed exercises of stock options 0 0 0 0 Weighted average shares and dilutive potential common shares 15,168 15,217 15,168 15,209 Diluted earnings per common share $ 0.64 $ 0.55 $ 1.26 $ 1.02

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS On September 7, 2018, the Corporation executed an interest rate swap agreement with a 5 -year term and an effective date of September 15, 2018 in order to hedge cash flows associated with $10 million of a subordinated note that was issued by the Corporation during 2007 and elected cash flow hedge accounting for the agreement. The Corporation’s objective in using this derivative is to add stability to interest expense and to manage its exposure to interest rate risk. The interest rate swap involves the receipt of variable-rate amounts in exchange for fixed-rate payments from September 15, 2018 to September 15, 2023 without the exchange of the underlying notional amount. At June 30, 2019 , the variable rate on the subordinated debt was 3.96% (LIBOR plus 155 basis points) and the Corporation was paying 4.53% ( 2.98% fixed rate plus 155 basis points). In order to hedge cash flows associated with $10 million of the subordinated note discussed above, on May 3, 2011, the Corporation executed an interest rate swap agreement with a 5 -year term and an effective date of September 15, 2013 that expired in September 2018. The Corporation’s objective in using this derivative was to add stability to interest expense and to manage its exposure to interest rate risk. The interest rate swap involved the receipt of variable-rate amounts in exchange for fixed-rate payments from September 15, 2013 to September 15, 2018 without exchange of the underlying notional amount. As of June 30, 2019 and December 31, 2018 , no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Corporation does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedges. The following tables provide information about the amounts and locations of activity related to the interest rate swaps designated as cash flow hedges within the Corporation’s consolidated balance sheet and statement of income as of June 30, 2019 and December 31, 2018 and for the three and six months ended June 30, 2019 and 2018 : Fair value as of Balance Sheet Location June 30, 2019 December 31, 2018 Interest rate contracts Accrued interest and other liabilities $ (526 ) $ (201 ) For the Three Months (a) (b) (c) (d) (e) Interest rate contracts $ (162 ) Interest expense – $ (14 ) Other $ 0 For the Six Months (a) (b) (c) (d) (e) Interest rate contracts $ (257 ) Interest expense – $ (20 ) Other $ 0 For the Three Months (a) (b) (c) (d) (e) Interest rate contracts $ 37 Interest expense – $ (46 ) Other $ 0 For the Six Months (a) (b) (c) (d) (e) Interest rate contracts $ 99 Interest expense – $ (105 ) Other $ 0 (a) Amount of Gain or (Loss) Recognized in Other Comprehensive Loss on Derivative (Effective Portion), net of tax (b) Location of Gain or (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income (Effective Portion) (c) Amount of Gain or (Loss) Reclassified from Accumulated Other Comprehensive Loss into Income (Effective Portion) (d) Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) (e) Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing) Amounts reported in accumulated other comprehensive loss related to the interest rate swap will be reclassified to interest expense as interest payments are made on the subordinated debentures. Such amounts reclassified from accumulated other comprehensive loss to interest expense in the next twelve months are expected to be $58 . As of June 30, 2019 and December 31, 2018 , a cash collateral balance in the amount of $600 and $200 , respectively, was maintained with a counterparty to the interest rate swaps. These balances are included in interest bearing deposits with other banks on the consolidated balance sheet. The Corporation entered into certain interest rate swap contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Corporation enters into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each swap transaction, the Corporation agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. Concurrently, the Corporation agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Corporation’s customers to effectively convert a variable rate loan to a fixed rate. Because the Corporation acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not impact the Corporation’s results of operations. The Corporation pledged cash collateral to another financial institution with a balance $1,850 as of June 30, 2019 and $750 as of December 31, 2018 . This balance is included in interest bearing deposits with other banks on the consolidated balance sheets. The Corporation may require its customers to post cash or securities as collateral on its program of back-to-back swaps depending upon the specific facts and circumstances surrounding each loan and individual swap. In addition, certain language is included in the International Swaps and Derivatives Association agreement and loan documents where, in default situations, the Corporation is permitted to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. The Corporation may be required to post additional collateral to swap counterparties in the future in proportion to potential increases in unrealized loss positions.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS All of the Corporation's revenue from contracts with customers in the scope of ASC 606 is recognized within non-interest income. The following table presents the Corporation's non-interest income by revenue stream and reportable segment for the three and six months ended June 30, 2019 and 2018 . Items outside the scope of ASC 606 are noted as such. Three months ended June 30, Six months ended June 30, 2019 2018 2019 2018 Non-interest Income Service charges on deposit accounts $ 1,569 $ 1,271 $ 3,050 $ 2,518 Wealth and asset management fees 1,202 1,090 2,244 2,120 Mortgage banking (1) 370 310 609 518 Card processing and interchange income 1,221 1,103 2,250 2,074 Net gains (losses) on sales of securities (1) 0 0 148 0 Other income 2,430 1,832 4,644 3,127 Total non-interest income $ 6,792 $ 5,606 $ 12,945 $ 10,357 (1) Not within scope of ASU 2014-9 Management determined that the primary sources of revenue emanating from interest and dividend income on loans and investment securities along with non-interest revenue resulting from security gains, loan servicing, gains on the sale of loans, commitment fees, fees from financial guarantees, certain credit card fees and gains (losses) on sale of other real estate owned not financed by the Corporation, are not within the scope of ASU 2014-9. As a result, no changes were made during the period related to these sources of revenue, which comprised 89.5% and 89.8% of the total revenue of the Corporation for the three and six months ended June 30, 2019 and 88.9% and 88.8% for the three and six months ended June 30, 2018 , respectively. The types of non-interest income within the scope of the standard that are material to the consolidated financial statements are services charges on deposit accounts, wealth and asset management fee income, card processing and interchange income, and other income. Service charges on deposit accounts : The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed, as that is the point in time the Corporation fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Services charges on deposits are withdrawn from the customer’s account balance. Wealth and asset management fees : The Corporation earns wealth and asset management fees from its contracts with trust and brokerage customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Corporation provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management at month end. Fees for these services are billed to customers on a monthly or quarterly basis and are recorded as revenue at the end of the period for which the wealth and asset management services have been performed. Other performance obligations, such as the delivery of account statements to customers, are generally considered immaterial to the overall transaction price. Card processing and interchange income : The Corporation earns interchange fees from check card and credit card transactions conducted through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Other income : The Corporation's other income includes sources such as bank owned life insurance, certain service fees, gains (losses) on sales of fixed assets, and gains (losses) on sale of other real estate owned. The service fees are recognized in the same manner as the service charges mentioned above. While gains on the sale of other real estate owned are generally within the scope of ASU 2014-9, the Corporation does not finance the sale of transactions and as such there is no change in revenue recognition.

Leases [Abstract]
Leases	LEASES As of January 1, 2019, the Corporation adopted certain accounting standard updates related to accounting for leases (Topic 842 - Leases), primarily ASU 2016-02 and subsequent updates. This guidance requires a lessee to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model. The Corporation adopted the provisions of ASU 2016-02 on January 1, 2019, and elected several practical expedients made available by the FASB. Specifically, the Corporation elected the transition practical expedient to not recast comparative periods upon the adoption of the new guidance. In addition, the Corporation elected to apply certain practical adoption expedients provided under the updates whereby we did not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases and (3) initial direct costs for any existing leases. As a result, the Corporation recognized approximately $12.5 million of right of use assets, approximately $800 thousand in prepaid rent, and $13.3 million of related lease liabilities as of January 1, 2019. Operating lease assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at lease commencement based on the present value of the remaining lease payments using a discount rate that represents our incremental borrowing rate at the lease commencement date. Operating lease cost, which is comprised of amortization of the operating lease asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term, and is recorded in net occupancy expense in the consolidated statements of income. The Corporation leases certain full-serve branch offices, land and equipment. Leases with an initial term of twelve months or less are not recorded on the balance sheet. Most leases include one or more options to renew and the exercise of the lease renewal options are at the Corporation's sole discretion. Certain lease agreements of the Corporation include rental payments adjusted periodically for changes in the consumer price index. Leases Classification June 30, 2019 Assets: Operating lease assets Operating lease assets $ 17,082 Finance lease assets Premises and equipment, net (1) 536 Total leased assets $ 17,618 Liabilities: Operating lease liabilities Operating lease liabilities $ 17,862 Finance lease liabilities Accrued interest payable and other liabilities 666 Total leased liabilities $ 18,528 (1) Finance lease assets are recorded net of accumulated amortization of $680 as of June 30, 2019 . The components of the Corporation's net lease expense for the three and six months ended June 30, 2019 were as follows: Three months ended June 30, Six months ended June 30, Lease Cost Classification 2019 2019 Operating lease cost Net occupancy expense $ 400 $ 805 Variable lease cost Net occupancy expense 15 49 Finance lease cost: Amortization of leased assets Net occupancy expense 18 36 Interest on lease liabilities Interest expense - borrowed funds 8 16 Sublease income (1) Net occupancy expense (20 ) (41 ) Net lease cost $ 421 $ 865 (1) Sublease income excludes rental income from owned properties. The following table sets forth future minimum rental payments under noncancelable leases with terms in excess of one year as of June 30, 2019 : Maturity of Lease Liabilities as of June 30, 2019 Operating Leases (1) Finance Leases Total 2019 $ 678 $ 52 $ 730 2020 1,430 105 1,535 2021 1,483 105 1,588 2022 1,537 105 1,642 2023 1,458 105 1,563 After 2023 17,938 315 18,253 Total lease payments 24,524 787 25,311 Less: Interest 6,662 121 6,783 Present value of lease liabilities $ 17,862 $ 666 $ 18,528 (1) Operating lease payments include payments related to options to extend lease terms that are reasonably certain of being exercised and exclude $3,173 of legally binding minimum lease payments for leases signed, but not yet commenced. Other information related to the Corporation's lease liabilities as of the six months ended June 30, 2019 was as follows: Lease Term and Discount Rate June 30, 2019 Weighted-average remaining lease term (years) Operating leases 17.1 Finance leases 7.5 Weighted-average discount rate Operating leases 3.61 % Finance leases 4.54 % Other Information June 30, 2019 Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from operating leases $ 409 Leased assets obtained in exchange from new operating lease liabilities 17,586

Commitments and Contingencies Disclosure [Abstract]
Contingency	CONTINGENCY On March 28, 2018, the Corporation received a notice of assessment from the Pennsylvania Department of Revenue that reported a sales tax assessment amount of $824 plus interest and penalties of $339 resulting in a total assessed balance of $1,163 . The notice of assessment covers the period from January 1, 2013 through July 31, 2016. The Corporation has evaluated the specific items on which sales tax has been assessed in conjunction with its legal counsel and has determined that it is probable that the Corporation has some liability based on a review of the Pennsylvania tax laws that apply to the assessed items. The Corporation’s reasonable estimate of this liability as of June 30, 2019 is $246 , of which $96 was accrued and previously reported in state and local tax expense in the consolidated statement of income during the year ended December 31, 2018. The remaining balance that has not been accrued relates primarily to sales tax assessments associated with data processing and banking equipment maintenance, which the Corporation’s management and legal counsel have concluded were improperly assessed based on current Pennsylvania sales tax law. The Corporation appealed the notice of assessment to the Pennsylvania Board of Appeals and the appeal was denied. The Corporation is in the process of appealing the assessment to the Pennsylvania Board of Finance and Revenue. The ultimate resolution of this matter, which may take in excess of one year, could result in an additional expense up to the total amount assessed.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In June 2016, the FASB issued an update (ASU 2016-13, Financial Instruments – Credit Losses) which will require recognition of an entity’s current estimate of all expected credit losses for assets measured at amortized cost. The amendments in ASU 2016-13 eliminate the probable initial recognition threshold in current GAAP. In addition, the amendments in ASU 2016-13 broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually, such as loans. The update will be effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for interim and annual reporting periods beginning after December 15, 2018. In November 2018, the FASB issued ASU 2018-19, "Codification Improvements to Topic 326, Financial Instruments – Credit Losses." The amendment clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20 and should be accounted for in accordance with Topic 842, "Leases." In April 2019, ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” was issued to address certain codification improvements and to provide certain accounting policy electives related to accrued interest as well as disclosure related to credit losses, among other things. In May 2019, ASU 2019-05, “Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief,” was issued to provide transition relief in connection with the adoption of ASU 2016-03 whereby entities would have the option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. The Corporation has formed a committee comprised of individuals from different disciplines, including credit administration, finance, loan servicing and information technology, to evaluate the requirements of the new standard and the impact it will have on current processes. Management continues to work through their implementation plan, including refinement of model assumptions, parallel testing, documentation of processes and internal controls and policy development with the assistance of a third-party. The new guidance is expected to be heavily influenced by an assessment of the composition, characteristics and credit quality of the Corporation's loan and investment securities portfolio, as well as the economic conditions in effect at the adoption date. The impact to the financial statements is yet to be determined. In August 2018, the FASB issued ASU 2018-14, "Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans." ASU 2018-14 amends ASC 715-20, "Compensation - Retirement Benefits - Defined Benefit Plans - General." The amended guidance modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated Other Comprehensive Income ("OCI") expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The update will be effective for annual reporting periods beginning after December 15, 2020, with early adoption permitted for annual reporting periods beginning after December 15, 2019. Management is currently evaluating the impact of the adoption of ASU 2018-14 on the Corporation’s footnote disclosures included in the financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies disclosure requirements on fair value measurements based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The update will be effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for interim and annual reporting periods beginning after December 15, 2018. Management is currently evaluating the impact of the adoption of ASU 2018-13 on the Corporation’s footnote disclosures included in the financial statements. In March 2019, the FASB issued an amendment (ASU 2019-01, Leases (Topic 842) Codification Improvements) which provides clarifications to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing essential information about leasing transactions. Specifically, ASU 2019-01 (i) allows the fair value of the underlying asset reported by lessors that are not manufacturers or dealers to continue to be its cost and not fair value as measured under the fair value definition, (ii) allows for the cash flows received for sales-type and direct financing leases to continue to be presented as results from investing, and (iii) clarifies that entities do not have to disclose the effect of the lease standard on adoption year interim amounts. The amendment will be effective for annual reporting periods beginning after December 15, 2019. Management does not expect the adoption of ASU 2019-01 will have any material impact on the Corporation’s financial statements.
