Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. 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 September 30, 2016 and for the three and nine month periods ended September 30, 2016 and 2015 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 nine month periods ended September 30, 2016 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, 2015. 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.

Business Combinations [Abstract]
Business Combination	2. BUSINESS COMBINATION On July 15, 2016, the Corporation completed its previously announced acquisition of Lake National Bank (“LNB”) of Mentor, Ohio for $22.50 per share in cash, resulting in consideration paid to LNB shareholders of $24.75 million. Following completion of the merger, the two branches of LNB in Mentor, Ohio are operating as part of the ERIEBANK division of CNB Bank. As disclosed in the accompanying consolidated statements of income, the Corporation incurred merger costs of $266 thousand and $481 thousand for the three and nine months ended September 30, 2016. All merger costs have been expensed as incurred. The following table summarizes the consideration paid for LNB and the amounts of the assets acquired and liabilities assumed that were recognized at the acquisition date: Consideration paid: Cash $ 24,750 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and cash equivalents 21,884 Securities available for sale 450 Loans 122,036 FHLB and other equity interests 637 Premises and equipment 3,242 Bank owned life insurance 2,152 Mortgage servicing rights 109 Core deposit intangible 1,583 Accrued interest receivable and other assets 3,301 Total assets acquired 155,394 Demand deposits 81,472 Time deposits 58,311 Accrued interest payable and other liabilities 2,634 Total liabilities assumed 142,417 Total identifiable net assets 12,977 Goodwill $ 11,773 Valuation of some assets acquired or created including, but not limited to, goodwill are preliminary and could be subject to change. Included in accrued interest receivable and other assets is a deferred tax asset of $249 which represents the tax effect of temporary differences between the tax basis and fair values assigned to the assets and liabilities. Acquired loans were recorded at fair value with no carryover of the related allowance for loan losses. Determining the fair value of loans involved estimating the amount and timing of principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. The Corporation acquired $126,134 of gross loans and recognized a net combined yield and credit mark of $4,098. Goodwill of $11,773 arising from the acquisition consisted largely of synergies and the cost savings resulting from the combining of the operations of the Corporation and Lake National Bank. None of the goodwill is expected to be deductible for income tax purposes.

Stock Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation	3. STOCK COMPENSATION The Corporation has a stock incentive plan for key employees and independent directors. The stock incentive plan, which is administered by a committee of the Board of Directors, provides for aggregate grants of up to 500,000 shares of common stock in the form of nonqualified options or restricted stock. For key employees, the plan vesting is one-fourth of the granted options or restricted stock per year beginning one year after the grant date, with 100% vested on the fourth anniversary of the grant date. For independent directors, the vesting schedule is one-third of the granted options or restricted stock per year beginning one year after the grant date, with 100% vested on the third anniversary of the grant date. At September 30, 2016, there was no unrecognized compensation cost related to nonvested stock options granted under this plan and no stock options were granted during the three and nine month periods ended September 30, 2016 and 2015. 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 these restricted stock awards was $216 and $628 for the three and nine months ended September 30, 2016 and $169 and $474 for the three and nine months ended September 30, 2015. As of September 30, 2016, there was $1,359 of total unrecognized compensation cost related to unvested restricted stock awards to be recognized over the next five years. A summary of changes in nonvested restricted stock awards for the three months ended September 30, 2016 follows: Per Share Weighted Shares Grant Date Nonvested at beginning of period 103,228 $ 17.35 Granted 750 18.40 Vested (150 ) 17.80 Nonvested at end of period 103,828 $ 17.35 A summary of changes in nonvested restricted stock awards for the nine months ended September 30, 2016 follows: Per Share Weighted Shares Grant Date Nonvested at beginning of period 84,600 $ 17.01 Granted 52,250 17.65 Vested (33,022 ) 16.92 Nonvested at end of period 103,828 $ 17.35 The fair value of shares vested was $3 and $559 during the three and nine month periods ended September 30, 2016.

Fair Value Disclosures [Abstract]
Fair Value	4. 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 structured pooled trust preferred securities are priced using Level 3 inputs. The decline in the level of observable inputs and market activity in this class of investments by the measurement date has been significant and resulted in unreliable external pricing. Broker pricing and bid/ask spreads, when available, vary widely, and the once-active market has become comparatively inactive. The Corporation engaged a third party consultant who has developed a model for pricing these securities. Information such as historical and current performance of the underlying collateral, deferral and default rates, collateral coverage ratios, break in yield calculations, cash flow projections, liquidity and credit premiums required by a market participant, and financial trend analysis with respect to the individual issuing financial institutions and insurance companies are utilized in determining the security valuation. Due to the current market conditions as well as the limited trading activity of these types of securities, the market value of the Corporation’s structured pooled trust preferred securities are highly sensitive to assumption changes and market volatility. 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).

Significant increases in specific-issuer default assumptions or decreases in specific-issuer recovery assumptions would result in a lower fair value measurement. Conversely, decreases in specific-issuer default assumptions or increases in specific-issuer recovery assumptions would result in a higher fair value measurement. Assets and liabilities measured at fair value on a non-recurring basis are as follows at September 30, 2016 and December 31, 2015: Fair Value Measurements at September 30, 2016 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 mortgages $ 2,002 0 0 $2,002 Fair Value Measurements at December 31, 2015 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 mortgages $ 2,247 0 0 $2,247 Impaired loans, measured for impairment using the fair value of collateral for collateral dependent loans, had a recorded investment of $3,202 with a valuation allowance of $1,200 as of September 30, 2016, resulting in an additional negative provision for loan losses of $(95) and $(42) for the corresponding three and nine month period ended September 30, 2016. Impaired loans had a recorded investment of $3,489 with a valuation allowance of $1,242 as of December 31, 2015. Impaired loans carried at fair value resulted in an additional provision for loan losses of $(361) and $(298) for the corresponding three and nine month period ended September 30, 2015. 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.

The estimated fair values would also not apply to subsequent dates. In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the disclosures. Also, non-financial assets such as, among other things, the estimated earning power of core deposits, the earnings potential of trust accounts, the trained workforce, and customer goodwill, which typically are not recognized on the balance sheet, may have value but are not included in the fair value disclosures.

A roll-forward of the other-than-temporary impairment amount related to credit losses for the three and nine months ended September 30, 2016 and 2015 is as follows: 2016 2015 Balance of credit losses on debt securities for which a portion of other-than-temporary impairment was recognized in earnings, beginning of period $ 4,054 $ 4,054 Credit losses previously recognized on securities sold during the period (1,983 ) 0 Additional credit loss for which other-than-temporary impairment was not previously recognized 0 0 Additional credit loss for which other-than-temporary impairment was previously recognized 0 0 Balance of credit losses on debt securities for which a portion of other-than-temporary impairment was recognized in earnings, end of period $ 2,071 $ 4,054 During the quarter ended June 30, 2016 the Corporation sold two structured pooled trust preferred securities which had been charged off in their entirety in prior periods. The original cost basis of these securities was $1,983 and the proceeds received totaled $922, which is reported in net realized gains on available-for-sale securities for the three and nine months ended September 30, 2016. Due to the insignificance of the Corporation’s adjusted amortized cost balance of the remaining structured pooled trust securities, no further disclosures are required. 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 September 30, 2016 and December 31, 2015, 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. Information pertaining to security sales on available for sale securities is as follows: Proceeds Gross Gains Gross Losses Three months ended September 30, 2016 $ 0 $ 0 $ 0 Nine months ended September 30, 2016 4,420 1,005 0 Three months ended September 30, 2015 38,025 244 (171 ) Nine months ended September 30, 2015 86,554 852 (288 ) The following is a schedule of the contractual maturity of securities available for sale, excluding equity securities, at September 30, 2016: Amortized Fair Cost Value 1 year or less $ 41,920 $ 41,532 1 year – 5 years 179,919 186,380 5 years – 10 years 70,832 73,920 After 10 years 17,135 18,261 309,806 320,093 Residential and multi-family mortgage 137,639 139,022 Pooled SBA 45,964 46,635 Total debt securities $ 493,409 $ 505,750 Mortgage and asset backed securities and pooled SBA securities are not due at a single date; periodic payments are received based on the payment patterns of the underlying collateral.

Loans	6. LOANS Total net loans at September 30, 2016 and December 31, 2015 are summarized as follows: September 30, 2016 December 31, 2015 Commercial, industrial, and agricultural $ 569,267 $ 475,364 Commercial mortgages 507,340 448,179 Residential real estate 644,545 574,225 Consumer 77,405 78,345 Credit cards 5,842 5,201 Overdrafts 73 1,040 Less: unearned discount (3,614 ) (4,556 ) allowance for loan losses (15,703 ) (16,737 ) Loans, net $ 1,785,155 $ 1,561,061 At September 30, 2016 and December 31, 2015, net unamortized loan fees of $(824) and $(636), respectively, have been included in the carrying value of loans. 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. All relevant documentation, such as the loan application, financial statements and tax returns, required under the lending policies is summarized and provided to management and/or the Corporation’s Board of Directors in connection with the loan approval process. Such documentation is subsequently electronically archived in the Corporation’s document management system. 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 32% and 30% of the Corporation’s total loan portfolio at September 30, 2016 and December 31, 2015. Commercial mortgage loans comprised 28% of the Corporation’s total loan portfolio at September 30, 2016 and December 31, 2015. 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. 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 36% of the Corporation’s total loan portfolio at September 30, 2016 and December 31, 2015. 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 through Freddie Mac. Loans originated for sale into the secondary market 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 represent less than 10% of the total loan portfolio at both September 30, 2016 and December 31, 2015. Terms and collateral requirements vary depending on the size and nature of the loan. CNB has not underwritten any hybrid loans, payment option loans, or low documentation/no documentation loans. Variable rate loans are generally underwritten at the fully indexed rate. Loan underwriting policies and procedures have not changed materially between any periods presented.

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 September 30, 2016 and December 31, 2015.

There was one loan modified as a troubled debt restructuring during the three and nine months ended September 30, 2016. Nine Months Ended September 30, 2016 Number of Loans Pre-Modification Post-Modification Commercial, industrial, and agricultural 1 $ 109 $ 109 Commercial mortgages 0 0 0 Residential real estate 0 0 0 Consumer 0 0 0 Credit cards 0 0 0 Total 1 $ 109 $ 109 There were no loans modified as troubled debt restructurings during the three or nine months ended September 30, 2015. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. All loans modified in troubled debt restructurings are performing in accordance with their modified terms as of September 30, 2016 and December 31, 2015 and no principal balances were forgiven in connection with the loan restructurings. In order to determine whether a borrower is experiencing financial difficulty, the Corporation performs an evaluation using its internal underwriting policies of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without a loan modification. The Corporation has no further loan commitments to customers whose loans are classified as a troubled debt restructuring. 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. Loans with outstanding balances greater than $1 million are analyzed at least semiannually and loans with outstanding balances of less than $1 million are analyzed at least annually. 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. September 30, 2016 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 530,168 $ 21,155 $ 17,936 $ 8 $ 569,267 Commercial mortgages 484,374 2,641 20,325 0 507,340 Total $ 1,014,542 $ 23,796 $ 38,261 $ 8 $ 1,076,607 December 31, 2015 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 447,449 $ 4,749 $ 22,943 $ 223 $ 475,364 Commercial mortgages 426,870 1,735 19,148 426 448,179 Total $ 874,319 $ 6,484 $ 42,091 $ 649 $ 923,543 The Corporation considers the performance of the loan portfolio and its impact on the allowance for loan losses. 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 September 30, 2016 and December 31, 2015: September 30, 2016 December 31, 2015 Residential Credit Residential Credit Real Estate Consumer Cards Real Estate Consumer Cards Performing $ 638,785 $ 76,220 $ 5,814 $ 570,467 $ 77,053 $ 5,201 Non-performing 5,760 1,185 28 3,758 1,292 0 Total $ 644,545 $ 77,405 $ 5,842 $ 574,225 $ 78,345 $ 5,201 The Corporation’s portfolio of residential real estate and consumer loans maintained within Holiday Financial Services Corporation (“Holiday”) are considered to be subprime loans. Holiday is a subsidiary that offers small balance unsecured and secured loans primarily collateralized by automobiles and equipment, to borrowers with higher risk characteristics than are typical in the Bank’s consumer loan portfolio.

Earnings Per Share [Abstract]
Earnings Per Share	8. EARNINGS PER SHARE Basic earnings per share is computed by dividing net income 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 nine months ended September 30, 2016 and 2015, there were no outstanding stock options to include in the diluted earnings per share calculations. 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 (in thousands except per share data): Three months ended Nine months ended September 30, September 30, 2016 2015 2016 2015 Basic earnings per common share computation: Net income per consolidated statements of income $ 6,416 $ 5,522 $ 15,500 $ 16,689 Net earnings allocated to participating securities (40 ) (30 ) (101 ) (92 ) Net earnings allocated to common stock $ 6,376 $ 5,492 $ 15,399 $ 16,597 Distributed earnings allocated to common stock $ 2,370 $ 2,363 $ 7,107 $ 7,095 Undistributed earnings allocated to common stock 4,006 3,129 8,292 9,502 Net earnings allocated to common stock $ 6,376 $ 5,492 $ 15,399 $ 16,597 Weighted average common shares outstanding, including shares considered participating securities 14,464 14,406 14,453 14,408 Less: Average participating securities (82 ) (71 ) (85 ) (72 ) Weighted average shares 14,382 14,335 14,368 14,336 Basic earnings per common share $ 0.44 $ 0.38 $ 1.07 $ 1.16 Diluted earnings per common share computation: Net earnings allocated to common stock $ 6,376 $ 5,492 $ 15,399 $ 16,597 Weighted average shares and dilutive potential common shares 14,382 14,335 14,368 14,336 Diluted earnings per common share $ 0.44 $ 0.38 $ 1.07 $ 1.16

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	9. DERIVATIVE INSTRUMENTS 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 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, 2013 to September 15, 2018 without exchange of the underlying notional amount. At September 30, 2016, the variable rate on the subordinated debt was 2.40% (LIBOR plus 155 basis points) and the Corporation was paying 5.57% (4.02% fixed rate plus 155 basis points). As of September 30, 2016 and December 31, 2015, 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 September 30, 2016 and December 31, 2015 and for the three and nine months ended September 30, 2016 and 2015: Fair value as of Balance Sheet September 30, December 31, Location 2016 2015 Interest rate contracts Accrued interest and other liabilities ($595) ($736) For the Three Months Ended September 30, 2016 (a) (b) (c) (d) (e) Interest rate contracts $87 Interest expense – ($84) Other $0 For the Nine Months Ended September 30, 2016 (a) (b) (c) (d) (e) Interest rate contracts $92 Interest expense – ($260) Other $0 For the Three Months Ended September 30, 2015 (a) (b) (c) (d) (e) Interest rate contracts ($19) Interest expense – ($95) Other $0 For the Nine Months Ended September 30, 2015 (a) (b) (c) (d) (e) Interest rate contracts $25 Interest expense – ($284) 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 $337. As of September 30, 2016 and December 31, 2015, a cash collateral balance in the amount of $1,400 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 has 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 of $200 as of September 30, 2016. This balance is included in interest bearing deposits with other banks on the consolidated balance sheets. The Corporation does not require its customers to post cash or securities as collateral on its program of back-to-back swaps. However, 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. The following table provides summary information about the amounts and locations of activity related to the back-to-back interest rate swaps within the Corporation’s consolidated balance sheet as of September 30, 2016 and December 31, 2015: Notional Average Weighted Weighted Average Fair September 30, 2016 3 rd Party interest rate swaps $ 10,326 10.1 3.90 % 1 month LIBOR + 2.03% $ 766 (f) Customer interest rate swaps (10,326 ) 10.1 3.90 % 1 month LIBOR + 2.03% (766 )(g) December 31, 2015 3 rd Party interest rate swaps $ 6,751 9.4 4.42 % 1 month LIBOR + 2.25% $ 131 (f) Customer interest rate swaps (6,751 ) 9.4 4.42 % 1 month LIBOR + 2.25% (131 )(g) (f) Reported in accrued interest receivable and other assets within the consolidated balance sheets (g) Reported in accrued interest payable and other liabilities within the consolidated balance sheets

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	10. RECENT ACCOUNTING PRONOUNCEMENTS In August 2016, the FASB issued an update (ASU 2016-15, Statement of Cash Flows) which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this Update apply to all entities, including business entities and not-for-profit entities that are required to present a statement of cash flows, and are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The adoption of ASU 2016-15 is not expected to have a material effect on the Corporation’s financial statements. 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 U.S. Generally Accepted Accounting Principles. 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. Management is currently evaluating the impact of the adoption of ASU 2016-13 on the Corporation’s financial statements. In March 2016, the FASB issued an update (ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting) which will require recognition of the income tax effects of share-based awards in the income statement when the awards vest or are settled (i.e., Additional Paid-in-Capital pools will be eliminated). The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of ASU 2016-09 is not expected to have a material effect on the Corporation’s financial statements. In March 2016, the FASB issued an update (ASU 2016-06, Derivatives and Hedging: Contingent Put and Call Options in Debt Instruments) which clarifies that an assessment of whether an embedded contingent put or call option is clearly and closely related to the debt host requires only an analysis of the four-step decision sequence in ASC 815-15-25-42. Entities are required to apply the guidance to existing debt instruments (or hybrid financial instruments that are determined to have a debt host) using a modified retrospective transition method as of the period of adoption. The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of ASU 2016-06 is not expected to have a material effect on the Corporation’s financial statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases (Topic 842)”. ASU 2016-02 requires a lessee to recognize lease assets and lease liabilities that arise from all leases. In addition, lessor accounting guidance will be changed to conform to the new guidance. The update will be effective for reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of the adoption of ASU 2016-02 on the Corporation’s financial statements. In January 2016, the FASB issued Accounting Standards Update 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 provides updated accounting and reporting requirements for both public and non-public entities. The most significant provisions that will impact the Corporation are: 1) equity securities available for sale will be measured at fair value, with the changes in fair value recognized in the income statement; 2) eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments at amortized cost on the balance sheet; 3) utilization of exit price notion when measuring the fair value of financial instruments for disclosure purposes; 4) require separate presentation of both financial assets and liabilities by measurement category and form of financial asset on the balance sheet or accompanying notes to the financial statements. The update will be effective for interim and annual reporting periods beginning after December 15, 2017, using a cumulative-effect adjustment to the balance sheet as of the beginning of the year adoption. Early adoption is not permitted. The adoption of ASU 2016-01 is not expected to have a material effect on the Corporation’s financial statements. In June 2014, the FASB issued Accounting Standards Update 2014-12, “Compensation – Stock Compensation (Topic 718)”. ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. No new disclosures are required under ASU 2014-12. The guidance is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2014-12 did not have a material effect on the Corporation’s financial statements. In May 2014, FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers (Topic 606).” The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance 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 or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Early adoption is not permitted. Management is currently evaluating the impact of the adoption of this guidance on the Corporation’s financial statements.

Accounting Changes and Error Corrections [Abstract]
Adoption of New Accounting Standards	In August 2016, the FASB issued an update (ASU 2016-15, Statement of Cash Flows) which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this Update apply to all entities, including business entities and not-for-profit entities that are required to present a statement of cash flows, and are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The adoption of ASU 2016-15 is not expected to have a material effect on the Corporation’s financial statements. 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 U.S. Generally Accepted Accounting Principles. 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. Management is currently evaluating the impact of the adoption of ASU 2016-13 on the Corporation’s financial statements. In March 2016, the FASB issued an update (ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting) which will require recognition of the income tax effects of share-based awards in the income statement when the awards vest or are settled (i.e., Additional Paid-in-Capital pools will be eliminated). The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of ASU 2016-09 is not expected to have a material effect on the Corporation’s financial statements. In March 2016, the FASB issued an update (ASU 2016-06, Derivatives and Hedging: Contingent Put and Call Options in Debt Instruments) which clarifies that an assessment of whether an embedded contingent put or call option is clearly and closely related to the debt host requires only an analysis of the four-step decision sequence in ASC 815-15-25-42. Entities are required to apply the guidance to existing debt instruments (or hybrid financial instruments that are determined to have a debt host) using a modified retrospective transition method as of the period of adoption. The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of ASU 2016-06 is not expected to have a material effect on the Corporation’s financial statements. In February 2016, the FASB issued Accounting Standards Update 2016-02, “Leases (Topic 842)”. ASU 2016-02 requires a lessee to recognize lease assets and lease liabilities that arise from all leases. In addition, lessor accounting guidance will be changed to conform to the new guidance. The update will be effective for reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of the adoption of ASU 2016-02 on the Corporation’s financial statements. In January 2016, the FASB issued Accounting Standards Update 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 provides updated accounting and reporting requirements for both public and non-public entities. The most significant provisions that will impact the Corporation are: 1) equity securities available for sale will be measured at fair value, with the changes in fair value recognized in the income statement; 2) eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments at amortized cost on the balance sheet; 3) utilization of exit price notion when measuring the fair value of financial instruments for disclosure purposes; 4) require separate presentation of both financial assets and liabilities by measurement category and form of financial asset on the balance sheet or accompanying notes to the financial statements. The update will be effective for interim and annual reporting periods beginning after December 15, 2017, using a cumulative-effect adjustment to the balance sheet as of the beginning of the year adoption. Early adoption is not permitted. The adoption of ASU 2016-01 is not expected to have a material effect on the Corporation’s financial statements. In June 2014, the FASB issued Accounting Standards Update 2014-12, “Compensation – Stock Compensation (Topic 718)”. ASU 2014-12 clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. No new disclosures are required under ASU 2014-12. The guidance is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2014-12 did not have a material effect on the Corporation’s financial statements. In May 2014, FASB issued Accounting Standards Update 2014-09, “Revenue from Contracts with Customers (Topic 606).” The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance 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 or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Early adoption is not permitted. Management is currently evaluating the impact of the adoption of this guidance on the Corporation’s financial statements.
