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, 2015 and for the three and nine month periods ended September 30, 2015 and 2014 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, 2015 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, 2014 (the “2014 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

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation	2. 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, 2015, 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, 2015 and 2014. 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 $169 and $474 for the three and nine months ended September 30, 2015, and $118 and $445 for the three and nine months ended September 30, 2014. As of September 30, 2015, there was $1,148 of total unrecognized compensation cost related to unvested restricted stock awards. A summary of changes in nonvested restricted stock awards for the three months ended September 30, 2015 follows: Per Share Weighted Average Shares Grant Date Fair Value Nonvested at beginning of period 89,850 $ 17.00 Granted 0 0 Vested (1,500 ) 17.00 Nonvested at end of period 88,350 $ 17.00 A summary of changes in nonvested restricted stock awards for the nine months ended September 30, 2015 follows: Per Share Weighted Average Shares Grant Date Fair Value Nonvested at beginning of period 68,210 $ 16.82 Granted 48,300 17.00 Vested (28,160 ) 16.56 Nonvested at end of period 88,350 $ 17.00

Fair Value Disclosures [Abstract]
Fair Value	3. 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 security is 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 this security. 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 security is highly sensitive to assumption changes and market volatility. The Corporation’s derivative instrument is an interest rate swap that is 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). Assets and liabilities measured at fair value on a recurring basis are as follows at September 30, 2015 and December 31, 2014: Fair Value Measurements at September 30, 2015 Using Description Total Quoted Prices in Significant Other Significant (Level 3) Assets: Securities Available For Sale: U.S. Government sponsored entities $ 147,009 $ 0 $ 147,009 $ 0 States and political subdivisions 180,429 0 180,429 0 Residential and multi-family mortgage 184,347 0 184,347 0 Corporate notes and bonds 19,036 0 19,036 0 Pooled trust preferred 1,160 0 0 1,160 Pooled SBA 54,359 0 54,359 0 Other securities 993 993 0 0 Total Securities Available For Sale $ 587,333 $ 993 $ 585,180 $ 1,160 Trading Securities: Corporate equity securities $ 2,997 $ 2,997 $ 0 $ 0 Mutual funds 1,028 1,028 0 0 Certificates of deposit 254 254 0 0 Corporate notes and bonds 155 0 155 0 U.S. Government sponsored entities 55 0 55 0 Total Trading Securities $ 4,489 $ 4,279 $ 210 $ 0 Liabilities, Interest rate swaps $ (908 ) $ 0 $ (908 ) $ 0 Fair Value Measurements at December 31, 2014 Using Description Total Quoted Prices in Significant Other Significant (Level 3) Assets: Securities Available For Sale: U.S. Government sponsored entities $ 155,564 $ 0 $ 155,564 $ 0 States and political subdivisions 181,002 0 181,002 0 Residential and multi-family mortgage 265,164 0 265,164 0 Corporate notes and bonds 19,430 0 19,430 0 Pooled trust preferred 905 0 0 905 Pooled SBA 62,653 0 62,653 0 Other securities 1,002 1,002 0 0 Total Securities Available For Sale $ 685,720 $ 1,002 $ 683,813 $ 905 Trading Securities: Corporate equity securities $ 3,044 $ 3,044 $ 0 $ Mutual funds 997 997 0 0 Certificates of deposit 253 253 0 0 Corporate notes and bonds 157 0 157 0 U.S. Government sponsored entities 54 0 54 0 Total Trading Securities $ 4,505 $ 4,294 $ 211 $ 0 Liabilities, Interest rate swaps $ (946 ) $ 0 $ (946 ) $ 0 The table below presents a reconciliation of the fair value of securities available for sale measured on a recurring basis using significant unobservable inputs (Level 3) for the three months ended September 30, 2015 and September 30, 2014: 2015 2014 Balance, July 1 $ 1,160 $ 798 Total gains or (losses): Included in other comprehensive income (unrealized) 0 73 Balance, September 30 $ 1,160 $ 871 The table below presents a reconciliation of the fair value of securities available for sale measured on a recurring basis using significant unobservable inputs (Level 3) for the nine months ended September 30, 2015 and September 30, 2014: 2015 2014 Balance, January 1 $ 905 $ 661 Total gains or (losses): Included in other comprehensive income (unrealized) 255 210 Balance, September 30 $ 1,160 $ 871 The following table presents quantitative information about Level 3 fair value measurements at September 30, 2015: Fair Valuation Unobservable Inputs Input Utilized Pooled trust preferred $ 1,160 Discounted cash flow Collateral default rate 0.63% and declining to 0.5% over the remainder of 2015 and thereafter Yield Prepayment speed 9% 2.0% constant prepayment rate in 2015 and thereafter The following table presents quantitative information about Level 3 fair value measurements at December 31, 2014: Fair Valuation Unobservable Inputs Input Utilized Pooled trust preferred $ 905 Discounted cash flow Collateral default rate 1% in 2015; 0.5% in 2016 and thereafter Yield Prepayment speed 11% 2.0% constant prepayment rate in 2015 and thereafter At September 30, 2015 and December 31, 2014, the significant unobservable inputs used in the fair value measurement of the Corporation’s pooled trust preferred security are collateral default rate, yield, and prepayment speed. Significant increases in specific-issuer default assumptions or decreases in specific-issuer recovery assumptions would result in a significantly 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, 2015 and December 31, 2014: Fair Value Measurements at September 30, 2015 Using Description Total Quoted Prices in Significant Other Significant Assets: Impaired loans: Commercial mortgages $ 2,426 0 0 $ 2,426 Commercial, industrial, and agricultural $ 2,824 0 0 $ 2,824 Fair Value Measurements at December 31, 2014 Using Description Total Quoted Prices in Significant Other Significant Assets: Impaired loans: Commercial mortgages $ 2,353 0 0 $ 2,353 Commercial, industrial, and agricultural $ 2,820 0 0 $ 2,820 Impaired loans, which, if collateral dependent, are measured for impairment using the fair value of collateral, had a recorded investment of $7,004 with a valuation allowance of $1,754 as of September 30, 2015, resulting in an additional provision for loan losses of ($361) and ($298) for the corresponding three and nine month period ended September 30, 2015. Impaired loans had a recorded investment of $7,423 with a valuation allowance of $2,250 as of December 31, 2014. Additional provision for loan losses were incurred of ($69) and $51 for the three and nine months ended September 30, 2014. The estimated fair values of impaired collateral dependent loans such as commercial or residential mortgages are determined primarily by using 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 management determines an updated appraisal is not necessary, an appropriate adjustment factor is applied based on 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, 2015 and 2014 is as follows: 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 Additional credit loss for which other-than-temporary impairment was not previously recognized 0 Additional credit loss for which other-than-temporary impairment was previously recognized 0 Balance of credit losses on debt securities for which a portion of other-than-temporary impairment was recognized in earnings, end of period $ 4,054 Due to the insignificance of the adjusted amortized cost balance, no further disclosures are required with respect to the Corporation’s structured pooled trust preferred securities. 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, 2015 and December 31, 2014, 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 the sale of available for sale securities is as follows: Proceeds Gross Gains Gross Losses Three months ended September 30, 2015 $ 38,025 $ 244 $ (171 ) Nine months ended September 30, 2015 86,554 852 (288 ) Three months ended September 30, 2014 9,698 41 0 Nine months ended September 30, 2014 38,826 328 (83 ) The following is a schedule of the contractual maturity of securities available for sale, excluding equity securities, at September 30, 2015: Amortized Fair Value 1 year or less $ 25,281 $ 25,501 1 year – 5 years 190,387 195,612 5 years – 10 years 94,600 95,971 After 10 years 30,132 30,550 340,400 347,634 Residential and multi-family mortgage 184,471 184,347 Pooled SBA 53,987 54,359 Total debt securities $ 578,858 $ 586,340 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	5. LOANS Total net loans at September 30, 2015 and December 31, 2014 are summarized as follows: September 30, 2015 December 31, 2014 Commercial, industrial, and agricultural $ 450,969 $ 428,458 Commercial mortgages 421,799 352,752 Residential real estate 566,045 502,317 Consumer 75,126 69,648 Credit cards 5,037 5,233 Overdrafts 1,543 1,188 Less: unearned discount (4,398 ) (4,307 ) allowance for loan losses (17,236 ) (17,373 ) Loans, net $ 1,498,885 $ 1,337,916 At September 30, 2015 and December 31, 2014, net unamortized loan fees and costs of $(160) and $483, 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 Western Pennsylvania and Central Ohio. 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 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 30% and 32% of the Corporation’s total loan portfolio at September 30, 2015 and December 31, 2014, respectively. Commercial mortgage loans comprised 28% and 26% of the Corporation’s total loan portfolio at September 30, 2015 and December 31, 2014, respectively. Management assigns a risk rating to all commercial loans in excess of $250,000. 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 37% and 37% of the Corporation’s total loan portfolio at September 30, 2015 and December 31, 2014, 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 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, 2015 and December 31, 2014. 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, 2015 and December 31, 2014. September 30, 2015 December 31, 2014 Number of Loans Loan Balance Specific Reserve Number of Loans Loan Balance Specific Reserve Commercial, industrial, and agricultural 7 $ 3,878 $ 960 7 $ 4,076 $ 179 Commercial mortgages 8 10,063 1,938 8 14,582 2,491 Residential real estate 0 0 0 0 0 0 Consumer 0 0 0 0 0 0 Credit cards 0 0 0 0 0 0 Total 15 $ 13,941 $ 2,898 15 $ 18,658 $ 2,670 There were no loans modified as troubled debt restructurings during the three or nine months ended September 30, 2015 and September 30, 2014. 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, 2015 and December 31, 2014 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. Generally, non-performing 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. 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, 2015 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 423,173 $ 4,438 $ 23,134 $ 224 $ 450,969 Commercial mortgages 405,251 0 16,120 428 421,799 Total $ 828,424 $ 4,438 $ 39,254 $ 652 $ 872,768 December 31, 2014 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 402,923 $ 6,703 $ 18,525 $ 307 $ 428,458 Commercial mortgages 328,614 0 23,699 439 352,752 Total $ 731,537 $ 6,703 $ 42,224 $ 746 $ 781,210 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, 2015 and December 31, 2014: September 30, 2015 December 31, 2014 Residential Consumer Credit Residential Consumer Credit Performing $ 562,226 $ 74,113 $ 5,037 $ 499,078 $ 68,603 $ 5,233 Non-performing 3,819 1,013 0 3,239 1,045 0 Total $ 566,045 $ 75,126 $ 5,037 $ 502,317 $ 69,648 $ 5,233 The Corporation’s portfolio of residential real estate and consumer loans maintained within Holiday Financial Services Corporation (“Holiday”) is considered to be subprime. 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. Holiday’s loan portfolio is summarized as follows at September 30, 2015 and December 31, 2014: September 30, December 31, 2015 2014 Consumer $ 28,790 $ 27,916 Residential real estate 1,184 1,270 Less: unearned discount (4,398 ) (4,307 ) Total $ 25,576 $ 24,879

Earnings Per Share [Abstract]
Earnings Per Share	7. 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, 2015, there were no outstanding stock options to include in the diluted earnings per share calculation. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are excluded 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 2015 2014 2015 2014 Basic earnings per common share computation: Net income per consolidated statements of income $ 5,522 $ 5,548 $ 16,689 $ 16,331 Net earnings allocated to participating securities (30 ) (23 ) (92 ) (70 ) Net earnings allocated to common stock $ 5,492 $ 5,525 $ 16,597 $ 16,261 Distributed earnings allocated to common stock $ 2,363 $ 2,359 $ 7,095 $ 7,109 Undistributed earnings allocated to common stock 3,129 3,166 9,502 9,152 Net earnings allocated to common stock $ 5,492 $ 5,525 $ 16,597 $ 16,261 Weighted average common shares outstanding, including shares considered participating securities 14,406 14,368 14,408 14,421 Less: Average participating securities (71 ) (53 ) (72 ) (55 ) Weighted average shares 14,335 14,315 14,336 14,366 Basic earnings per common share $ 0.38 $ 0.39 $ 1.16 $ 1.13 Diluted earnings per common share computation: Net earnings allocated to common stock $ 5,492 $ 5,525 $ 16,597 $ 16,261 Weighted average common shares outstanding for basic earnings per common share 14,335 14,315 14,336 14,366 Add: Dilutive effects of assumed exercises of stock options 0 1 0 1 Weighted average shares and dilutive potential common shares 14,335 14,316 14,336 14,367 Diluted earnings per common share $ 0.38 $ 0.39 $ 1.16 $ 1.13

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	8. 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, 2015, the variable rate on the subordinated debt was 1.84% (LIBOR plus 155 basis points) and the Corporation was paying 5.57% (4.02% fixed rate plus 155 basis points). As of September 30, 2015 and December 31, 2014, 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, 2015 and December 31, 2014 and for the three and nine months ended September 30, 2015 and 2014: Fair value as of Balance Sheet September 30, December 31, Location 2015 2014 Interest rate contracts Accrued interest and other liabilities ($908) ($ 946 ) 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 For the Three Months Ended September 30, 2014 (a) (b) (c) (d) (e) Interest rate contracts $ 99 Interest expense – ($ 96 ) Other $ 0 For the Nine Months Ended September 30, 2014 (a ) (b) (c) (d) (e) Interest rate contracts ($ 117 ) Interest expense – ($ 287 ) 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 $381. As of September 30, 2015 and December 31, 2014, 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.

Recent Accounting Pronouncements	9. RECENT ACCOUNTING PRONOUNCEMENTS In January 2014, the FASB issued Accounting Standards Update 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40)” (ASU 2014-04). The amendments in ASU 2014-04 clarify the circumstances under which an in substance repossession or foreclosure occurs and when a creditor is considered to have received physical possession of a residential real estate property collateralizing a residential real estate loan. The amendments in ASU 2014-04 also require interim and annual disclosure of the amount of foreclosed residential real estate property held by the creditor and the recorded investment in loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU 2014-04 is effective for reporting periods beginning after December 15, 2014. The effect of adopting ASU 2014-04 did not have a material effect on the Corporation’s financial statements. In June 2014, the FASB issued ASU 2014-11 “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”. The amendments in ASU 2014-11 change the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The amendments also require two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. 2014-11 is effective for reporting periods beginning after December 15, 2014. The effect of adopting ASU 2014-11 did not have a material effect on the Corporation’s financial statements. In June 2014, the FASB issued ASU 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 effect of adopting ASU 2014-12 is not expected to have a material effect on the Corporation’s financial statements.
