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 June 30, 2017 and for the three and six month periods ended June 30, 2017 and 2016 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 periods ended June 30, 2017 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, 2016 (the “2016 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 June 30, 2017, 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 six month periods ended June 30, 2017 and 2016. On February 14, 2017, the Corporation’s Board of Directors granted performance-based restricted stock awards (“PBRSAs”) with a range of 5,306 to 7,959 shares to an employee. The number of PBRSAs will depend on certain performance conditions and are also subject to service-based vesting. 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 $207 and $396 for the three and six months ended June 30, 2017 and $172 and $412 for the three and six months ended June 30, 2016. As of June 30, 2017, there was $1,786 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 June 30, 2017 follows: Per Share Weighted Average Shares Grant Date Fair Value Nonvested at beginning of period 99,683 $ 20.67 Forfeited (150 ) 17.63 Vested (300 ) 17.83 Nonvested at end of period 99,233 $ 20.68 A summary of changes in nonvested restricted stock awards for the six months ended June 30, 2017 follows: Per Share Weighted Average Shares Grant Date Fair Value Nonvested at beginning of period 100,726 $ 17.36 Granted 38,123 25.92 Forfeited (150 ) 17.63 Vested (39,466 ) 17.28 Nonvested at end of period 99,233 $ 20.68 The fair value of shares vested was $6 and $0 during the three months ended June 30, 2017 and 2016, respectively. The fair value of shares vested was $923 and $542 during the six months ended June 30, 2017 and 2016, respectively.

Fair Value

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 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). 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.

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 June 30, 2017 and December 31, 2016: Fair Value Measurements at June 30, 2017 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 $ 11 0 0 $ 11 Fair Value Measurements at December 31, 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 $ 2,067 0 0 $ 2,067 Impaired loans, measured for impairment using the fair value of collateral for collateral dependent loans, had a recorded investment of $690 with a valuation allowance of $679 as of June 30, 2017, resulting in a negative provision for loan losses of ($271) and ($373) for the corresponding three and six month periods ended June 30, 2017. Impaired loans had a recorded investment of $3,120 with a valuation allowance of $1,053 as of December 31, 2016. Impaired loans carried at fair value resulted in an additional provision for loan losses of $135 and $53 for the three and six month periods ended June 30, 2016. 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 for 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 earnings 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 six months ended June 30, 2017 and 2016 is as follows: 2017 2016 Balance of credit losses on debt securities for which a portion of other-than-temporary impairment was recognized in earnings, beginning of period $ 2,071 $ 4,054 Credit losses previously recognized on securities sold during the period (2,071 ) (1,983 ) 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 $ 0 $ 2,071 The adjusted amortized cost of structured pooled trust preferred securities as of December 31, 2016 is insignificant. 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. 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, 2017 and December 31, 2016, 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, 2017 and December 31, 2016, securities carried at $302,593 and $329,379, 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 Gross Three months ended June 30, 2017 $ 5,434 $ 155 $ 0 Three months ended June 30, 2016 $ 4,420 $ 1,005 $ 0 Six months ended June 30, 2017 $ 7,618 $ 1,538 $ 0 Six months ended June 30, 2016 $ 4,420 $ 1,005 $ 0 The tax provision related to these net realized gains was $54 and $538 during the three and six months ended June 30, 2017 and $352 during both the three and six months ended June 30, 2016. The following is a schedule of the contractual maturity of securities available for sale, excluding equity securities, at June 30, 2017: Amortized Fair Cost Value 1 year or less $ 47,977 $ 47,728 1 year – 5 years 170,873 174,756 5 years – 10 years 63,058 64,999 After 10 years 8,206 8,264 290,114 295,747 Residential and multi-family mortgage 117,039 116,781 Pooled SBA 39,736 39,565 Total debt securities $ 446,889 $ 452,093 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 June 30, 2017 and December 31, 2016 are summarized as follows: June 30, 2017 December 31, 2016 Commercial, industrial, and agricultural $ 636,836 $ 567,800 Commercial mortgages 618,262 574,826 Residential real estate 684,294 652,883 Consumer 76,476 74,816 Credit cards 6,080 6,046 Overdrafts 2,359 595 Less: unearned discount (3,478 ) (3,430 ) allowance for loan losses (17,269 ) (16,330 ) Loans, net $ 2,003,560 $ 1,857,206 At June 30, 2017 and December 31, 2016, net unamortized loan (fees) costs of $(2,347) and $(1,507), 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, Central and Northeastern 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 31% and 30% of the Corporation’s total loan portfolio at June 30, 2017 and December 31, 2016, respectively. Commercial mortgage loans comprised 31% and 31% of the Corporation’s total loan portfolio at June 30, 2017 and December 31, 2016, 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 34% and 35% of the Corporation’s total loan portfolio at June 30, 2017 and December 31, 2016, 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 represent less than 10% of the total loan portfolio at both June 30, 2017 and December 31, 2016. 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, 2017 and December 31, 2016.

A troubled debt restructured 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 June 30, 2017 and December 31, 2016 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. 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. June 30, 2017 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 601,561 $ 9,575 $ 25,700 $ 0 $ 636,836 Commercial mortgages 599,015 3,100 16,147 0 618,262 Total $ 1,200,576 $ 12,675 $ 41,847 $ 0 $ 1,255,098 December 31, 2016 Pass Special Substandard Doubtful Total Commercial, industrial, and agricultural $ 531,320 $ 14,638 $ 21,831 $ 11 $ 567,800 Commercial mortgages 551,474 1,809 21,543 0 574,826 Total $ 1,082,794 $ 16,447 $ 43,374 $ 11 $ 1,142,626 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 June 30, 2017 and December 31, 2016: June 30, 2017 December 31, 2016 Residential Credit Residential Credit Real Estate Consumer Cards Real Estate Consumer Cards Performing $ 678,606 $ 75,734 $ 6,068 $ 647,283 $ 73,817 $ 6,036 Nonperforming 5,688 742 12 5,600 999 10 Total $ 684,294 $ 76,476 $ 6,080 $ 652,883 $ 74,816 $ 6,046 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	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 six months ended June 30, 2017 and 2016, 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 Six months ended June 30, June 30, 2017 2016 2017 2016 Basic earnings per common share computation: Net income per consolidated statements of income $ 6,683 $4,065 $ 13,163 $ 9,084 Net earnings allocated to participating securities (40 ) (27 ) (78 ) (60 ) Net earnings allocated to common stock $ 6,643 $ 4,038 $ 13,085 $ 9,024 Distributed earnings allocated to common stock $ 2,507 $ 2,369 $ 5,015 $ 4,737 Undistributed earnings allocated to common stock 4,136 1,669 8,070 4,287 Net earnings allocated to common stock $ 6,643 $ 4,038 13,085 $ 9,024 Weighted average common shares outstanding, including shares considered participating securities 15,294 14,460 15,138 14,448 Less: Average participating securities (88 ) (92 ) (87 ) (86 ) Weighted average shares 15,206 14,368 15,051 14,362 Basic earnings per common share $ 0.44 $ 0.28 $ 0.87 $ 0.63 Diluted earnings per common share computation: Net earnings allocated to common stock $ 6,643 $ 4,038 $ 13,085 $ 9,024 Weighted average shares and dilutive potential common shares 15,206 14,368 15,051 14,362 Diluted earnings per common share $ 0.44 $ 0.28 $ 0.87 $ 0.63

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 June 30, 2017, the variable rate on the subordinated debt was 2.80% (LIBOR plus 155 basis points) and the Corporation was paying 5.57% (4.02% fixed rate plus 155 basis points). As of June 30, 2017 and December 31, 2016, 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, 2017 and December 31, 2016 and for the three and six months ended June 30, 2017 and 2016: Fair value as of Balance Sheet June 30, December 31, Location 2017 2016 Interest rate contracts Accrued interest and other liabilities $ (313 ) $ (459 ) For the Three Months Ended June 30, 2017 (a) (b) (c) (d) (e) Interest rate contracts $ 40 Interest expense – ($ 74 ) Other $ 0 For the Six Months Ended June 30, 2017 (a ) (b) (c) (d) (e) Interest rate contracts $ 95 Interest expense – ($ 149 ) Other $ 0 For the Three Months Ended June 30, 2016 (a) (b) (c) (d) (e) Interest rate contracts ($ 31 ) Interest ($ 86 ) Other $ 0 For the Six Months Ended June 30, 2016 (a ) (b) (c) (d) (e) Interest rate contracts $ 5 Interest ($ 176 ) 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 $289. As of June 30, 2017 and December 31, 2016, 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 $750 as of both June 30, 2017 and December 31, 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 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 June 30, 2017 and December 31, 2016: Notional Amount Weighted Average Maturity (in years) Weighted Average Fixed Rate Weighted Average Variable Rate Fair Value June 30, 2017 3 rd Party interest rate swaps $ 14,647 8.5 4.43 % 1 month LIBOR + 2.35% $ 235 (a) Customer interest rate swaps (14,647 ) 8.5 4.43 % 1 month LIBOR + 2.35% (235 )(b) December 31, 2016 3 rd Party interest rate swaps $ 14,814 9.0 4.43 % 1 month LIBOR + 2.35% $ 211 (a) Customer interest rate swaps (14,814 ) 9.0 4.43 % 1 month LIBOR + 2.35% (211 )(b) (a) Reported in accrued interest receivable and other assets within the consolidated balance sheets (b) Reported in accrued interest payable and other liabilities within the consolidated balance sheets

Recent Accounting Pronouncements	11. RECENT ACCOUNTING PRONOUNCEMENTS In May 2017, the FASB issued an update (ASU 2017-09, Compensation – Stock Compensation) to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation – Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, and the amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of ASU 2017-09 is not expected to have a material effect on the Corporation’s financial statements. In January 2017, the FASB issued an update (ASU 2017-04, Intangibles – Goodwill and Other) which is intended to simplify the measurement of goodwill in periods following the date on which the goodwill is initially recorded. Under the amendments in this update, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. However, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. A public business entity that is a U.S. Securities and Exchange Commission filer should adopt the amendments in this update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of ASU 2017-04 is not expected to have a material effect on the Corporation’s financial statements. 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 in the developmental stages of evaluating the impact of the adoption of ASU 2016-13 on the Corporation’s financial statements and is collecting available historical information in order to assess the expected credit losses. Although management expects the allowance for loan losses will increase upon the adoption of ASU 2016-13, the impact to the financial statements is yet to be determined. In March 2016, the FASB issued Accounting Standards Update 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 requires 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 became effective in the first quarter of 2017 and did not 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 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 and Topic 606, Revenue from Contracts with Customers. 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 and anticipates an increase in the Corporation’s assets and liabilities. However, the amounts that will be adjusted are still to be determined. 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 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, along with disclosures related to the disaggregation of revenues and associated risks. 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 permitted. Management is currently reviewing contracts and agreements associated with the generation of non-interest income, and the adoption of ASU 2014-09 is not expected to have a material effect on the Corporation’s financial statements.
