Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Unless otherwise indicated, dollar amounts are in thousands, except per share data. Business and Organization CNB Financial Corporation (the “Corporation”) is headquartered in Clearfield, Pennsylvania, and provides a full range of banking and related services through its wholly owned subsidiary, CNB Bank (the “Bank”). In addition, the Bank provides trust and asset management services, including the administration of trusts and estates, retirement plans, and other employee benefit plans as well as a full range of wealth management services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. In addition to the Bank, the Corporation also operates a consumer discount loan and finance business through its wholly owned subsidiary, Holiday Financial Services Corporation (“Holiday”). The Corporation and these and its other subsidiaries are subject to examination by federal and state regulators. The Corporation’s market area is primarily concentrated in the central and northwest regions of the Commonwealth of Pennsylvania and in the central region of the state of Ohio. Basis of Financial Presentation The financial statements are consolidated to include the accounts of the Corporation and the Bank, CNB Securities Corporation, Holiday, and CNB Insurance Agency. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity. Use of Estimates To prepare financial statements in conformity with accounting principles generally accepted in the U.S., management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. Interest Bearing Time Deposits with Other Banks Interest-bearing time deposits in other financial institutions mature within one year and are carried at cost. Securities When purchased, securities are classified as held to maturity, trading or available for sale. Debt securities are classified as held to maturity when the Corporation has the positive intent and ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost. Debt or equity securities are classified as trading when purchased principally for the purpose of selling them in the near term, or when the fair value option has been elected. Trading securities are recorded at fair value with changes in fair value included in earnings in non-interest income. Available for sale securities are those securities not classified as held to maturity or trading and are carried at their fair value. Unrealized gains and losses, net of deferred tax, on securities classified as available for sale are recorded as other comprehensive income. Management has not classified any debt securities as held to maturity. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for the amortization of premiums and the accretion of discounts over the period through contractual maturity or, in the case of mortgage-backed securities and collateralized mortgage obligations, over the estimated life of the security. Such amortization is included in interest income from securities. Gains and losses on securities sold are recorded on the trade date and based on the specific identification method. Declines in the fair value of debt securities below their cost that are other than temporary and attributable to credit losses are reflected in earnings. Other-than-temporary impairment losses that are not attributable to credit losses are reported as a component of accumulated other comprehensive income. In estimating other-than-temporary losses, management considers: the length of time and extent that fair value has been less than cost, the financial condition and near term prospects of the issuer, and the Corporation’s intent to sell, or whether it is more likely than not that it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. If the Corporation intends to sell a security or it is more likely than not it will be required to sell a security before recovery of its amortized cost basis, the entire difference between amortized cost and fair value is recognized as impairment through earnings. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Interest income on commercial, industrial, and agricultural loans, commercial mortgage loans, and residential real estate loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Consumer loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. Loans, including loans modified in a troubled debt restructuring, are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received on loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. For all portfolio segments, loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Concentration of Credit Risk Most of the Corporation’s business activity is with customers located within the Commonwealth of Pennsylvania and the state of Ohio. Therefore, the Corporation’s exposure to credit risk is significantly affected by changes in the economies of Pennsylvania and Ohio. Purchased Loans The Corporation purchased loans in connection with its acquisition of FC Banc Corp. in 2013, some of which had, at the acquisition date, shown evidence of credit deterioration since origination. These purchased credit impaired loans were recorded at the amount paid, such that there was no carryover of the seller’s allowance for loan losses. Further losses on purchased credit impaired loans are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually, and the Corporation estimates the amount and timing of expected cash flows for each loan. The expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. For loans purchased that did not show evidence of credit deterioration, the difference between the fair value of the loan at the acquisition date and the loan’s face value is being amortized as a yield adjustment over the estimated remaining life of the loan using the effective interest method. Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of the mortgage loan sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance account. Management determines the adequacy of the allowance based on historical patterns of charge-offs and recoveries, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, industry experience, economic conditions, and other qualitative factors relevant to the collectability of the loan portfolio. While management believes that the allowance is adequate to absorb probable loan losses incurred at the balance sheet date, future adjustments may be necessary due to circumstances that differ substantially from the assumptions used in evaluating the adequacy of the allowance for loan losses. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Commercial and commercial real estate loans are individually evaluated for impairment. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. Troubled debt restructurings are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component of the allowance for loan losses covers non-impaired The following portfolio segments, which are the same as the Corporation’s portfolio classifications and associated risk characteristics, have been identified: ● Commercial, industrial, and agricultural – risk characteristics include below average economic and employment conditions in many of the markets served by the Corporation, which has limited consumer spending. ● Commercial mortgages – the most significant risk characteristic is the subjectivity involved in real estate valuations for properties located in areas with low growth economies. ● Residential real estate – risk characteristics include slightly higher than historical levels of delinquencies and less than robust housing markets. ● Consumer – risk characteristics include continuing weakness in industrial employment in many of the markets served by the Corporation and low wage growth. ● Credit cards – the most significant risk characteristic is the unsecured nature of credit card loans. ● Overdrafts – risk characteristics include the Corporation’s continued deposit growth and overall economic conditions which may lead to a greater likelihood of overdrawn deposit accounts. Federal Home Loan Bank (FHLB) Stock As a member of the Federal Home Loan Bank of Pittsburgh (“FHLB”), the Corporation is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. FHLB stock is held as a long-term investment, is valued at its cost basis and is analyzed for impairment based on the ultimate recoverability of the par value. The Company evaluates impairment quarterly. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following: ● its operating performance; ● the severity and duration of declines in the fair value of its net assets related to its capital stock amount; ● its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; ● the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of FHLB; and ● its liquidity and funding position. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Depreciation of premises and equipment is computed principally by the straight line method. In general, useful lives range from 3 to 39 years with lives for furniture, fixtures and equipment ranging from 3 to 10 years and lives of buildings and building improvements ranging from 15 to 39 years. Amortization of leasehold improvements is computed using the straight-line method over useful lives of the leasehold improvements or the term of the lease, whichever is shorter. Maintenance, repairs and minor renewals are charged to expense as incurred. Foreclosed Assets Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at the lower of cost or fair value, less estimated costs to sell. If fair value declines, a valuation allowance is recorded through expense. Costs after acquisition are expensed. Bank Owned Life Insurance The Corporation has purchased life insurance policies on certain key employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Goodwill and Other Intangible Assets Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate an impairment test should be performed. The Corporation has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives. Goodwill is the only intangible asset with an indefinite life on the Corporation’s balance sheet. Other intangible assets consist of a core deposit intangible asset arising from the acquisition of FC Banc Corp. in 2013. The core deposit intangible asset is amortized using an accelerated method over its estimated useful life of 7 years. Long-term Assets Premises and equipment, goodwill and other intangible assets, and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Derivatives Derivative financial instruments are recognized as assets or liabilities at fair value. The Corporation has interest rate swap agreements which are used as part of its asset liability management to help manage interest rate risk. The Corporation does not use derivatives for trading purposes. At the inception of a derivative contract, the Corporation designates the derivative as one of three types based on the purpose of the contract and belief as to its effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. Advertising Costs Advertising costs are generally expensed as incurred and amounted to $1,580, $1,455, and $939, for 2015, 2014 and 2013, respectively. Mortgage Servicing Rights Servicing rights are recognized separately when they are acquired through sales of loans. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Corporation compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement as mortgage banking income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material. Treasury Stock The purchase of the Corporation’s common stock is recorded at cost. Purchases of the stock are made both in the open market and through negotiated private purchases based on market prices. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a first-in-first-out basis. Stock-Based 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 up to 500,000 shares of common stock to be awarded in the form of nonqualified options or restricted stock. For key employees, the plan vesting schedule is one-fourth of granted stock-based awards per year beginning one year after the grant date with 100% vested on the fourth anniversary. For independent directors, the vesting schedule is one-third of granted stock-based awards per year beginning one year after the grant date with 100% vested on the third anniversary. At December 31, 2015 and 2014, there was no unrecognized compensation cost related to nonvested stock options granted under this plan, and no stock options were granted during the years ended December 31, 2015, 2014 and 2013. During 2015, 2014 and 2013, the Executive Compensation and Personnel Committee of the Board of Directors granted a total of 48,300, 35,400 and 31,500 shares, respectively, of restricted common stock to certain key employees and all independent directors of the Corporation. Compensation expense for the restricted stock awards is recognized over the requisite service period based on the fair value of the shares at the date of grant on a straight-line basis. Unearned restricted stock awards are recorded as a reduction of shareholders’ equity until earned. Compensation expense resulting from these restricted stock awards was $621, $548 and $390 for the years ended December 31, 2015, 2014 and 2013, respectively. Comprehensive Income The Corporation presents comprehensive income as part of the Consolidated Statement of Income and Comprehensive Income. Other comprehensive income (loss) consists of unrealized holding gains (losses) on the available for sale securities portfolio, changes in the unrecognized actuarial gain and transition obligation related to the Corporation’s post retirement benefits plans, and changes in the fair value of the Corporation’s interest rate swaps. Income Taxes The Corporation files a consolidated U.S. income tax return that includes all subsidiaries. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense. Retirement Plans The Corporation’s expense associated with its 401(k) plan is determined under the provisions of the plan document and includes both matching and profit sharing components. Deferred compensation and supplemental retirement plan expenses allocate the benefits over years of service. Earnings Per Share Basic earnings per share is computed by dividing net income available to common shareholders 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. 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 non-vested stock awards are participating securities. Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Corporation defines cash and cash equivalents as cash and due from banks, interest bearing deposits with other banks, and Federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing time deposits with other banks and borrowings with original maturities of 90 days or less. Restrictions on Cash The Bank is required to maintain average reserve balances with the Federal Reserve Bank or in vault cash. The average amount of these non-interest bearing reserve balances for the year ended December 31, 2015 and 2014, was $50, which was maintained in vault cash. Note 12 to the consolidated financial statements discloses the cash collateral balances required to be maintained in connection with the Corporation’s interest rate swaps. Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements. Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. Adoption of New Accounting Standards 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 adoption of ASU 2014-04 did not have a material effect on the Corporation’s financial statements. In August 2014, the FASB issued Accounting Standards Update 2014-14, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure.” ASU 2014-14 amended existing guidance related to the classification of certain government-guaranteed mortgage loans, including those guaranteed by the FHA and the VA, upon foreclosure. It requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if certain conditions are met. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of ASU 2014-14 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 this ASU change the accounting for repurchase-to-maturity transactions and linked repurchas

Business Combinations [Abstract]
Business Combination	2. Business Combination In the first quarter of 2013, the Corporation announced the signing of a definitive merger agreement to acquire 100% of the outstanding equity interests of FC Banc Corp. and its subsidiary, Farmers Citizens Bank, for $30.00 per share in cash and stock. Farmers Citizens Bank served the central Ohio markets of Bucyrus, Cardington, Fredericktown, Mount Hope and Shiloh, as well as the markets of Worthington and Upper Arlington in the greater Columbus, Ohio area, with 8 branch locations. The transaction closed on October 11, 2013 and resulted in consideration paid to FC Banc Corp. shareholders totaling approximately $41.6 million, comprised of approximately $8.0 million in cash and 1,873,879 shares of the Corporation’s common stock valued at approximately $33.6 million based on the October 11, 2013 closing price of $17.91 per share. FC Banc Corp.’s results of operations were included in the Corporation’s results beginning October 12, 2013. On December 30, 2015, the Corporation announced the signing of a definitive merger agreement to acquire Lake National Bank of Mentor, Ohio for $22.50 per share in cash, or approximately $24.75 million in the aggregate. The transaction is expected to close in the third quarter of 2016, subject to customary closing conditions, including regulatory approvals and the approval of Lake National Bank shareholders. Following completion of the merger, Lake National Bank will operate as part of the ERIEBANK division of CNB Bank. As of December 31, 2015, Lake National Bank had total assets of $153.0 million, total loans of $122.3 million, and total deposits of $134.8 million. The Corporation’s management and board of directors have periodically conducted strategic reviews as part of their ongoing efforts to improve the Corporation’s banking franchise and enhance shareholder value. In connection with these strategic reviews, the Corporation has considered potential acquisition targets, including banking institutions in Ohio. On March 26, 2013, the Corporation’s board of directors unanimously approved the merger transaction with FC Banc Corp. and authorized the Corporation’s management to execute and deliver the merger agreement. As disclosed in the accompanying consolidated statements of income, the Corporation incurred merger costs of $308 during the year ended December 31, 2015 and $2,396 during the year ended December 31, 2013. All merger costs have been expensed as incurred. The following table summarizes the consideration paid for FC Banc Corp. and the amounts of the assets acquired and liabilities assumed that were recognized at the acquisition date: Consideration paid: Cash $ 8,013 Common stock 33,561 Fair value of total consideration transferred 41,574 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and cash equivalents 54,995 Securities available for sale 34,214 Loans 247,737 FHLB and other equity interests 1,789 Premises and equipment 4,328 Bank owned life insurance 3,955 Mortgage servicing rights 83 Core deposit intangible 4,834 Accrued interest receivable and other assets 8,093 Total assets acquired 360,028 Demand deposits 248,812 Time deposits 83,214 Accrued interest payable and other liabilities 2,676 Total liabilities assumed 334,702 Total identifiable net assets 25,326 Goodwill $ 16,248 Included in accrued interest receivable and other assets is a deferred tax asset totaling $5,696 representing the tax effect of temporary differences between the tax basis and fair values assigned to the assets and liabilities, as well as the effect of FC Banc Corp.’s net operating loss carryforward. See Note 13. 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. Loans acquired with evidence of credit quality deterioration totaled $2,225. The Corporation acquired $256,418 of gross loans, including purchased credit impaired loans, and recognized a net combined yield and credit mark of $8,681. Goodwill of $16,248 arising from the acquisition consisted largely of synergies and the cost savings resulting from the combining of the operations of the Corporation and FC Banc Corp. None of the goodwill is expected to be deductible for income tax purposes.

The following table provides detailed information related to the Corporation’s structured pooled trust preferred securities as of December 31, 2015 and for the years ended December 31, 2015, 2014, and 2013: As of December 31, 2015 Credit Losses Realized in Adjusted Unrealized Fair Year Ended December 31, Cost Gain (Loss) Value 2015 2014 2013 ALESCO Preferred Funding V, Ltd. $ 800 $ 370 $ 1,170 $ 0 $ 0 $ 0 ALESCO Preferred Funding XII, Ltd. 0 1,021 1,021 0 0 0 ALESCO Preferred Funding XVII, Ltd. 0 588 588 0 0 0 Preferred Term Securities XVI, Ltd. 0 634 634 0 0 0 US Capital Funding VI, Ltd. 0 0 0 0 0 0 Total $ 800 $ 2,613 $ 3,413 $ 0 $ 0 $ 0 At December 31, 2015, the Corporation evaluated the pooled trust preferred securities for other than-temporary impairment by estimating the cash flows expected to be received, taking into account future estimated levels of deferrals and defaults by the underlying issuers and discounting those cash flows at the appropriate accounting yield. A roll-forward of the other-than-temporary impairment amount related to credit losses for the years ended December 31, 2015, 2014 and 2013 is as follows: 2015 2014 2013 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 $ 4,054 Additional credit loss for which other-than-temporary impairment was not previously recognized 0 0 0 Additional credit loss for which other-than-temporary impairment was previously recognized 0 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 $ 4,054 $ 4,054 $ 4,054 The adjusted amortized cost of structured pooled trust preferred securities as of December 31, 2015 and 2014, 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 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 December 31, 2015 and 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.

Loans	5. Loans Total net loans at December 31, 2015 and 2014 are summarized as follows: 2015 2014 Commercial, industrial, and agricultural $ 475,364 $ 428,458 Commercial mortgages 448,179 352,752 Residential real estate 574,225 502,317 Consumer 78,345 69,648 Credit cards 5,201 5,233 Overdrafts 1,040 1,188 Less: unearned discount (4,556 ) (4,307 ) allowance for loan losses (16,737 ) (17,373 ) Loans, net $ 1,561,061 $ 1,337,916 At December 31, 2015 and 2014 net unamortized loan (fees) costs of $(636) 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. 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 December 31, 2015 and 2014, respectively. Commercial mortgage loans comprised 28% and 26% of the Corporation’s total loan portfolio at December 31, 2015 and 2014, 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 36% and 37% of the Corporation’s total loan portfolio at December 31, 2015 and 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 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 December 31, 2015 and 2014. Terms and collateral requirements vary depending on the size and nature of the loan. During 2014, management reviewed its loan portfolio segments resulting in the reclassification of approximately $136 million into Commercial, Industrial and Agricultural. $124 million was reclassified out of Commercial Mortgages and $12 million was reclassified out of Residential Real Estate. Accordingly, the December 31, 2013 loan portfolio segment balances and the related allowance for loan loss segments were reclassified to conform to the December 31, 2014 presentation. To roll forward the allowance for loan losses by segments for the year ended 2013, the net effect of this reclassification was adjusted through provisions for loan losses. The effect of this reclassification was not considered material to the overall allowance for loan losses, did not change total loan balances, and is not considered material to the consolidated financial statements taken as a whole. Transactions in the allowance for loan losses for the year ended December 31, 2015 were as follows: Commercial, Commercial Residential Consumer Credit Overdrafts Total Allowance for loan losses, January 1, 2015 $ 7,114 $ 5,310 $ 2,479 $ 2,205 $ 71 $ 194 $ 17,373 Charge-offs (307 ) (486 ) (632 ) (1,956 ) (116 ) (221 ) (3,718 ) Recoveries 267 52 8 96 14 85 522 Provision for loan losses (1,039 ) 729 620 2,026 121 103 2,560 Allowance for loan losses, December 31, 2015 $ 6,035 $ 5,605 $ 2,475 $ 2,371 $ 90 $ 161 $ 16,737 Transactions in the allowance for loan losses for the year ended December 31, 2014 were as follows: Commercial, Commercial Residential Consumer Credit Overdrafts Total Allowance for loan losses, January 1, 2014 $ 8,212 $ 3,536 $ 2,450 $ 1,763 $ 66 $ 207 $ 16,234 Charge-offs (618 ) (50 ) (436 ) (1,744 ) (78 ) (256 ) (3,182 ) Recoveries 1 210 41 93 25 111 481 Provision for loan losses (481 ) 1,614 424 2,093 58 132 3,840 Allowance for loan losses, December 31, 2014 $ 7,114 $ 5,310 $ 2,479 $ 2,205 $ 71 $ 194 $ 17,373 Transactions in the allowance for loan losses for the year ended December 31, 2013 were as follows: Commercial, Commercial Residential Consumer Credit Overdrafts Total Allowance for loan losses, January 1, 2013 $ 4,940 $ 4,697 $ 2,466 $ 1,699 $ 83 $ 175 $ 14,060 Charge-offs (958 ) (1,931 ) (467 ) (1,919 ) (97 ) (258 ) (5,630 ) Recoveries 7 1,430 5 114 16 94 1,666 Provision for loan losses 4,223 (660 ) 446 1,869 64 196 6,138 Allowance for loan losses, December 31, 2013 $ 8,212 $ 3,536 $ 2,450 $ 1,763 $ 66 $ 207 $ 16,234 The following table presents the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and is based on the Corporation’s impairment method as of December 31, 2015 and 2014.

Modifications involving a reduction of the stated interest rate of the loan were for periods ranging from 4-15 A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. Except as discussed below, all loans modified in troubled debt restructurings are performing in accordance with their modified terms as of December 31, 2015 and 2014 and no principal balances were forgiven in connection with the loan restructurings. During the year ended December 31, 2015 one impaired commercial industrial loan having a balance of $1,327 was modified in troubled debt restructurings. The Corporation did not record any additional provision for loan losses for this loan during the year ended December 31, 2015. During the year ended December 31, 2014, three impaired commercial mortgage loans having combined balances of $4,879 were modified in troubled debt restructurings. The Corporation recorded additional provision for loan losses of $271 for these loans during the year ended December 31, 2014. In addition, an impaired commercial industrial loan having a balance of $2,315 was modified in a troubled debt restructuring. The Corporation recorded an additional provision for loan losses of $48 for this loan during the year ended December 31, 2014. During the year ended December 31, 2013, the Corporation recorded a partial charge-off of $974 for a commercial mortgage loan with a balance of $1,660 that had defaulted under its restructured terms in 2012 and was placed on nonaccrual status. The Corporation recorded an additional provision for loan losses of $262 on this loan during the year ended December 31, 2013. A commercial mortgage loan with a balance of $1,086 defaulted under its restructured terms in 2013 and was placed on nonaccrual status. The Corporation recorded an additional provision for loan losses of $615 during the year ended December 31, 2013. In addition, an impaired commercial mortgage loan that was placed on non-accrual status in 2013 and having a balance of $3,269 was modified in a troubled debt restructuring. The Corporation recorded an additional provision for loan losses of $514 for this loan during the year ended December 31, 2013. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without a loan modification. This evaluation is performed using the Corporation’s internal underwriting policies. The Corporation has no further loan commitments to customers whose loans are classified as a troubled debt restructuring. Generally, 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. 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 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 December 31, 2015 and December 31, 2014: December 31, 2015 December 31, 2014 Residential Consumer Credit Residential Consumer Credit Performing $ 570,467 $ 77,053 $ 5,201 $ 499,078 $ 68,603 $ 5,233 Non-performing 3,758 1,292 0 3,239 1,045 0 Total $ 574,225 $ 78,345 $ 5,201 $ 502,317 $ 69,648 $ 5,233 The Corporation’s portfolio of residential real estate and consumer loans maintained within Holiday Financial Services Corporation (“Holiday”), 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, are considered to be subprime loans.

In 2015, the Corporation entered into a contractual commitment to construct a branch facility in Worthington, Ohio at a cost of $5,948. Construction has commenced with $2,006 of construction in process as of December 31, 2015. The project is expected to be completed by the end of the fourth quarter of 2016. In 2014, the Corporation entered into a contractual commitment to remodel its main office facility in Clearfield, Pennsylvania at a cost of $9,935. Construction in the amount of $5,658 has been completed, and $4,277 was in process as of December 31, 2015. The project is expected to be completed by the end of the first quarter of 2016. The Corporation is committed under nineteen noncancelable operating leases for facilities and thirteen noncancelable operating leases for vehicles with initial or remaining terms in excess of one year. The minimum annual rental commitments under these leases at December 31, 2015 are as follows: 2016 $ 907 2017 692 2018 440 2019 356 2020 237 Thereafter 1,967 $ 4,599 Rental expense, net of rental income, charged to occupancy expense for 2015, 2014, and 2013 was $699, $736, and $490, respectively. In December 2009, the Corporation entered into a sale-leaseback transaction for real estate used in the operations of one of its branch office locations. The lease term is seventeen years, with two automatic renewal terms of five years each. The Corporation sold the property for $1,200 but financed the entire sales amount. Because the buyer/lessor did not make an initial investment on the purchase of the real estate that is adequate to transfer the risks and rewards of ownership, the Corporation deferred the entire gain of $489 associated with this transaction, which is included in accrued interest payable and other liabilities in the accompanying consolidated balance sheet. The gain is being recognized over the term of the loan under the installment method, and the gain recognized was included in other income in the accompanying consolidated statements of income and comprehensive income and totaled $22, $19, and $17 in 2015, 2014, and 2013, respectively. The minimum annual rental commitments under this sale-leaseback transaction at December 31, 2015 are as follows: 2016 $ 105 2017 105 2018 105 2019 105 2020 105 Thereafter 630 $ 1,155

Step 1 includes the determination of the carrying value of our single reporting unit, including the existing goodwill and intangible assets, and estimating the fair value of the reporting unit. We determined the fair value of our reporting unit exceeded its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, we are required to perform a second step to the impairment test. Our annual impairment analysis at December 31, 2015 and 2014 indicated that the Step 2 analysis was not necessary. Intangible Assets In connection with its acquisition of FC Banc Corp. in 2013, the Corporation recorded a core deposit intangible asset of $4,834. During the years ended December 31, 2015 and 2014, the Corporation recorded amortization expense of $1,008 and $1,180, respectively, resulting in a net carrying value of $2,395 at December 31, 2015 and $3,403 at December 31, 2014.

Borrowings	11. Borrowings At December 31, 2015 and 2014, the Corporation had available one $10 million line of credit with an unaffiliated institution, at a variable interest rate with a floor as defined in the agreement. There were no borrowings on the line of credit at December 31, 2015 and 2014. FHLB Borrowings At December 31, 2015, the Bank had remaining borrowing capacity with the FHLB of $392,986. At December 31, 2015, borrowings with the FHLB are secured by a pledge of selected securities in the amount of $20,619 and certain loans with a balance of $802,174 at December 31, 2015.

The terms of borrowings (a) through (g) as well as (j) are interest only payments with principal due at maturity. Each advance is payable at its maturity date, with a prepayment penalty for fixed rate advances. Other Borrowings At December 31, 2015 and 2014, the Bank had no outstanding borrowings from unaffiliated institutions under overnight borrowing agreements. The Bank entered into a borrowing transaction with an unaffiliated institution in March 2007. The proceeds of this borrowing were $10,000 and, as part of this transaction, the Bank pledged certain securities which had a carrying amount of $11,710 at December 31, 2015. The borrowing has a maturity date of March 20, 2017. The borrowing is callable by the issuer at the end of each quarter until maturity. The interest rate is fixed and was 5.25% at December 31, 2015 and 2014. Subordinated Debentures In 2007, the Corporation issued two $10,000 floating rate trust preferred securities as part of a pooled offering of such securities. The interest rate on each offering is determined quarterly and floats based on the 3 month LIBOR plus 1.55% and was 2.06% at December 31, 2015 and 1.79% at December 31, 2014. The Corporation issued subordinated debentures to the trusts in exchange for the proceeds of the offerings, which debentures represent the sole assets of the trusts. The subordinated debentures must be redeemed no later than 2037. The Corporation may redeem the debentures, in whole or in part, at face value at any time. The Corporation has the option to defer interest payments from time to time for a period not to exceed five consecutive years. Although the trusts are variable interest entities, the Corporation is not the primary beneficiary. As a result, because the trusts are not consolidated with the Corporation, the Corporation does not report the securities issued by the trusts as liabilities. Instead, the Corporation reports as liabilities the subordinated debentures issued by the Corporation and held by the trusts, since the liabilities are not eliminated in consolidation. Maturity Schedule of All Borrowed Funds The following is a schedule of maturities of all borrowed funds as of December 31, 2015: 2016 $ 136,361 2017 70,351 2018 5,335 2019 4,130 2020 308 Thereafter 24,650 Total borrowed funds $ 241,135

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swaps	12. Interest Rate Swaps 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 December 31, 2015, the variable rate on the subordinated debt was 2.06% (LIBOR plus 155 basis points) and the Corporation was paying 5.57% (4.02% fixed rate plus 155 basis points). On August 1, 2008, the Corporation executed an interest rate swap agreement with a 5 year term and an effective date of September 15, 2008 in order to hedge cash flows associated with $10 million of a subordinated note discussed above. The Corporation’s objective in using this derivative was to add stability to interest expense and to manage its exposure to interest rate risk. The interest rate swap involved the receipt of variable-rate amounts in exchange for fixed-rate payments from September 15, 2008 to the September 15, 2013 maturity date without exchange of the underlying notional amount. As of December 31, 2015 and 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 December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014, and 2013: As of December 31 Liability Derivative Balance Sheet Fair value Location 2015 2014 Interest rate contract Accrued interest payable and other liabilities ($736) ($946) For the Year Ended December 31, 2015 (a) (b) (c) (d) (e) Interest rate contract $137 Interest expense – subordinated debentures ($378) Other $0 For the Year Ended December 31, 2014 Interest rate contract $111 Interest expense – subordinated debentures ($384) Other $0 For the Year Ended December 31, 2013 Interest rate contract $409 Interest expense – subordinated debentures ($400) 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 $351. As of December 31, 2015 and 2014, a cash collateral balance of $1,400 was maintained with the counterparty to the interest rate swaps. These balances are included in interest bearing deposits with other banks on the consolidated balance sheets. During 2015, the Corporation entered into certain interest rate swap contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Corporation enters into an interest rate swap with a customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each swap transaction, the Corporation agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. Concurrently, the Corporation agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Corporation’s customers to effectively convert a variable rate loan to a fixed rate. Because the Corporation acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not impact the Corporation’s results of operations. The Corporation pledged cash collateral to another financial institution with a balance of $200 as of December 31, 2015. 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 December 31, 2015: 3 rd party interest rate swap Customer interest rate swap Notional amount $6,751 $6,751 Maturity date August 1, 2025 August 1, 2025 Fixed rate 4.42% 4.42% Variable rate 1 month LIBOR + 2.25% 1 month LIBOR + 2.25% Fair value $131 (f) ($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

During 2015, the Corporation generated additional net capital losses of $222 which were unable to be utilized and expire December 31, 2020. The associated deferred tax assets of $90 and $13 as of December 31, 2015 and 2014, respectively, are included in other deferred tax assets. The Corporation determined that it was not required to establish a valuation allowance for deferred tax assets since management believes that the deferred tax assets are likely to be realized through a carry back to taxable income in prior years, future reversals of existing temporary differences, future net capital gains and future taxable income. The reconciliation of income tax attributable to pre-tax income at the federal statutory tax rates to income tax expense is as follows: 2015 % 2014 % 2013 % Tax at statutory rate $ 10,671 35.0 $ 11,336 35.0 $ 8,057 35.0 Tax exempt income, net (1,816 ) (6.0 ) (1,684 ) (5.2 ) (1,664 ) (7.2 ) Bank owned life insurance (418 ) (1.4 ) (364 ) (1.1 ) (543 ) (2.4 ) Merger costs 30 0.1 0 0.0 233 1.0 Other (175 ) (0.5 ) 26 0.1 257 1.1 Income tax expense $ 8,292 27.2 $ 9,314 28.8 $ 6,340 27.5 At December 31, 2015 and 2014, the Corporation has no unrecognized tax benefits. The Corporation does not expect the total amount of unrecognized tax benefits to significantly increase in the next twelve months. The Corporation recognizes interest and/or penalties related to income tax matters as part of income tax expense. At December 31, 2015 and 2014, there were no amounts accrued for interest and/or penalties and no amounts recorded as expense for the years ending December 31, 2015, 2014 and 2013. The Corporation and its subsidiaries are subject to U.S. federal income tax as well as income tax of the Commonwealth of Pennsylvania. The Corporation is no longer subject to examination by the taxing authorities for years prior to 2012. Tax years 2012 through 2014 remain open to federal and state examination. In connection with its acquisition of FC Banc Corp., the Corporation assumed a federal net operating loss carryforward of $6,367, which expires in 2033. Under Section 382 of the Internal Revenue Code, the utilization of the loss carryforward in future years is limited based on the consideration paid and other factors. The annual limitation on the utilization of this loss carry forward is $1,455. As of December 31, 2015, the balance of the net operating loss carryforward is $3,248. Management believes that the net operating loss carryforward will be used in full before its expiration.

Employee Benefit Plans	14. Employee Benefit Plans The Corporation sponsors a contributory defined contribution Section 401(k) plan in which substantially all employees participate. The plan permits employees to make pre-tax contributions which are matched by the Corporation at 100% for every 1% contributed up to three percent then 50% for every 1% contributed up to the next four percent in total of the employee’s compensation. The Corporation’s matching contribution and related expenses were $508, $620, and $431 in 2015, 2014, and 2013, respectively. Profit sharing contributions to this plan, based on current year compensation, are 6 percent of total compensation plus 5.7 percent of the compensation in excess of $119. The Corporation recognized profit sharing expense of $868, $1,044, and $855 in 2015, 2014, and 2013 respectively. The Corporation has adopted a non-qualified supplemental executive retirement plan (“SERP”) for certain executives to compensate those executive participants in the Corporation’s retirement plan whose benefits are limited by compensation limitations under current tax law. The SERP is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the SERP are payable from the general assets of the Corporation. At December 31, 2015 and 2014, obligations of $4,666 and $4,316, respectively, were included in other liabilities for this plan. Expenses related to this plan were $608 in 2015, $454 in 2014, and $541 in 2013. The Corporation has established a Survivor Benefit Plan for the benefit of outside directors. The purpose of the plan is to provide life insurance benefits to beneficiaries of the Corporation’s directors who at the time of their death are participants in the plan. The plan is considered an unfunded plan for tax and ERISA purposes and all obligations arising under the plan are payable from the general assets of the Corporation. At December 31, 2015 and 2014, obligations of $1,142 and $987, respectively, were included in other liabilities for this plan. Expenses related to this plan were $155 in 2015, $55 in 2014, and $119 in 2013. The Corporation has an unfunded post retirement benefits plan which provides certain health care benefits for retired employees who have reached the age of 60 and retired with 30 years of service. The plan was amended in 2013 to include only employees hired prior to January 1, 2000. Benefits are provided for these retired employees and their qualifying dependents from the age of 60 through the age of 65. The following table sets forth the change in the benefit obligation of the plan as of and for the years ended December 31, 2015, 2014, and 2013: 2015 2014 2013 Benefit obligation at beginning of year $ 2,744 $ 2,485 $ 2,224 Interest cost 90 102 84 Service cost 96 84 125 Actual claims (109 ) (108 ) (167 ) Plan amendment 0 0 (602 ) Actuarial loss 245 181 821 Benefit obligation at end of year $ 3,066 $ 2,744 $ 2,485 Amounts recognized in accumulated other comprehensive income at December 31, 2015 and 2014 consist of: 2015 2014 Net actuarial loss $ (1,773 ) $ (1,635 ) Tax effect 620 572 $ (1,153 ) $ (1,063 ) The accumulated benefit obligation was $3,066 and $2,744 at December 31, 2015 and 2014, respectively.

The weighted average discount rate used to calculate net periodic benefit cost was 3.42% in 2015, 4.31% in 2014, and 3.88% in 2013. The weighted average rate used to calculate accrued benefit obligations was 3.67% in 2015, 3.42% in 2014, and 4.31% in 2013. The health care cost trend rate used to measure the expected costs of benefits is 5.0% for 2016 and thereafter. A one percent increase in the health care trend rates would result in an increase of $300 in the benefit obligation as of December 31, 2015, and would increase the service and interest costs by $24 in future periods. A similar one percent decrease in health care trend rates would result in a decrease of $267 and $21 in the benefit obligation and services and interest costs, respectively, at December 31, 2015.

Banking and Thrift [Abstract]
Capital Requirements and Restrictions on Retained Earnings	18. Capital Requirements and Restrictions on Retained Earnings Banks and financial holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, for the Bank, prompt corrective action (PCA) regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory enforcement actions. Management believes as of December 31, 2015 the Corporation and Bank meet all capital adequacy requirements to which they are subject. The PCA regulations provide five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms alone do not represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion; brokered deposits may not be accepted, renewed or rolled over; and capital restoration plans are required. As of December 31, 2015 and 2014, the most recent regulatory notifications categorized the Bank as well capitalized under the PCA regulatory framework. There are no events or conditions since this notification that management believes have changed the Bank’s capital category. Actual and required capital amounts and ratios are presented below as of December 31, 2015 and 2014: Actual For Capital To Be Well Capitalized Amount Ratio Amount Ratio Amount Ratio December 31, 2015 Total Capital to Risk Weighted Assets Consolidated $212,711 13.18 % $129,135 8.0 % N/A Bank $193,301 12.07 % $128,132 8.0 % $160,166 10.0 % Tier 1 (Core) Capital to Risk Weighted Assets Consolidated $195,974 12.14 % $96,851 6.0 % N/A Bank $178,353 11.14 % $96,099 6.0 % $128,132 8.0 % Common equity Tier 1 to Risk Weighted Assets Consolidated $175,974 10.90 % $72,638 4.5 % N/A Bank $170,974 10.67 % $72,074 4.5 % $104,108 6.5 % Tier 1 (Core) Capital to Average Assets Consolidated $195,974 8.73 % $89,782 4.0 % N/A Bank $178,353 8.06 % $88,464 4.0 % $110,581 5.0 % December 31, 2014 Total Capital to Risk Weighted Assets Consolidated $199,034 14.30 % $111,374 8.0 % N/A Bank $180,597 13.16 % $109,758 8.0 % $137,198 10.0 % Tier 1 (Core) Capital to Risk Weighted Assets Consolidated $181,661 13.05 % $55,687 4.0 % N/A Bank $164,835 12.01 % $54,879 4.0 % $82,319 6.0 % Tier 1 (Core) Capital to Average Assets Consolidated $181,661 8.39 % $86,641 4.0 % N/A Bank $164,835 7.71 % $85,503 4.0 % $106,878 5.0 % The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The net unrealized gain or loss on available for sales securities is included in computing regulatory capital. Capital amounts and ratios for December 31, 2014 are calculated using Basel I rules. Certain restrictions exist regarding the ability of the Bank to transfer funds to the Corporation in the form of cash dividends, loans or advances. During 2016, $24,216 of accumulated net earnings of the Bank included in consolidated stockholders’ equity, plus any 2016 net profits retained to the date of the dividend declared, is available for distribution to the Corporation as dividends without prior regulatory approval, subject to regulatory capital requirements described above.

Off Balance Sheet Activities	19. Off Balance Sheet Activities Some financial instruments, such as loan commitments, credit lines, letters of credit, and overdraft protection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off balance sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment. The contractual amount of financial instruments with off balance sheet risk was as follows at December 31, 2015 and 2014: 2015 2014 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $42,803 $259,032 $28,831 $254,269 Unused lines of credit 0 87,493 0 80,428 Standby letters of credit 0 15,704 0 15,132 Commitments to make loans are generally made for periods of 60 days or less. The fixed rate loan commitments at December 31, 2015 have interest rates ranging from 1.19% to 18.00% and maturities ranging from 3 months to 20 years. The fixed rate loan commitments at December 31, 2014 have interest rates ranging from 1.69% to 18.00% and maturities ranging from 3 months to 20 years. In October 2015, the Corporation entered into a subscription agreement with Oxer BCP Mezzanine Fund, LP (“Oxer”) and committed to invest $5,000 as a limited partner in the fund. Oxer is a Small Business Investment Company (SBIC) that is licensed and regulated by the Office of Investment at the Small Business Administration (SBA). The SBIC license allows SBICs to employ private capital and funds borrowed at a low cost using SBA-guaranteed securities to make investments in qualifying small businesses and similar enterprises as defined by SBA regulations. As of December 31, 2015, Oxer’s general partner had not requested any of the capital committed by its limited partner investors.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	20. 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. Assets and liabilities measured at fair value on a recurring basis are as follows at December 31, 2015 and 2014: Fair Value Measurements at December 31, 2015 Using Description Total Quoted Prices in Significant Other Significant (Level 3) Assets: Securities Available For Sale: U.S. Government sponsored entities $ 141,751 $ 0 $ 141,751 $ 0 States and political subdivisions 171,819 0 171,819 0 Residential and multi-family mortgage 157,982 0 157,982 0 Corporate notes and bonds 18,688 0 18,688 0 Pooled trust preferred 3,413 0 0 3,413 Pooled SBA 51,409 0 51,409 0 Other equity securities 981 981 0 0 Total Securities Available For Sale $ 546,043 $ 981 $ 541,649 $ 3,413 Interest Rate swaps: $ 131 $ 0 $ 131 $ 0 Trading Securities: Corporate equity securities $ 3,389 $ 3,389 $ 0 $ 0 Mutual funds 750 750 0 0 Certificates of deposit 253 253 0 0 Corporate notes and bonds 130 130 0 0 U.S. Government sponsored entities 54 0 54 0 Total Trading Securities $ 4,576 $ 4,522 $ 54 $ 0 Liabilities, Interest rate swaps $ (867 ) $ 0 $ (867 ) $ 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 equity 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 $ 0 Mutual funds 999 999 0 0 Certificates of deposit 253 253 0 0 Corporate notes and bonds 155 155 0 0 U.S. Government sponsored entities 54 0 54 0 Total Trading Securities $ 4,505 $ 4,451 $ 54 $ 0 Liabilities, Interest rate swaps $ (946 ) $ 0 $ (946 ) $ 0 The table below presents a reconciliation and income statement classification of gains and losses for all securities available for sale measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the year ended December 31, 2015: Pooled Balance, January 1, 2015 $ 905 Total gains or (losses): Included in other comprehensive income (loss) 2,508 Included in realized gains on available-for-sale securities 0 Sale of available-for-sale securities 0 Balance, December 31, 2015 $ 3,413 The table below presents a reconciliation and income statement classification of gains and losses for all securities available for sale measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the year ended December 31, 2014: Pooled Balance, January 1, 2014 $ 661 Total gains or (losses): Included in other comprehensive income (loss) 244 Included in realized gains on available-for-sale securities 0 Sale of available-for-sale securities 0 Balance, December 31, 2014 $ 905 The following table presents quantitative information about Level 3 fair value measurements at December 31, 2015: Fair Valuation Unobservable Input Utilized Pooled trust preferred $3,413 Discounted cash flow Collateral default rate Yield 1% in 2015; 0.5% in 2016 and thereafter 9% Prepayment speed 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 Input Utilized Pooled trust preferred $905 Discounted cash flow Collateral default rate Yield 1% in 2015; 0.5% in 2016 and thereafter 11% Prepayment speed 2.0% constant prepayment rate in 2015 and thereafter At December 31, 2015 and 2014, the significant unobservable inputs used in the fair value measurement of the Corporation’s pooled trust preferred securities 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 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 December 31, 2015 and 2014: Fair Value Measurements at December 31, 2015 Using Description Total Quoted Prices in (Level 1) Significant Other (Level 2) Significant (Level 3) Assets: Impaired loans: Commercial mortgages $ 2,247 0 0 $ 2,247 Fair Value Measurements at December 31, 2014 Using Description Total Quoted Prices in (Level 1) Significant Other (Level 2) Significant (Level 3) Assets: Impaired loans: Commercial mortgages $ 2,353 0 0 $ 2,353 Commercial, industrial, and agricultural 2,820 0 0 2,820 Impaired loans measured for impairment using the fair value of collateral for collateral dependent loans had a recorded investment of $3,489, with a valuation allowance of $1,242 as of December 31, 2015, resulting in an additional provision for loan losses of $414 for the year then ended. Impaired loans had a recorded investment of $7,423, with a valuation allowance of $2,250 as of December 31, 2014, resulting in an additional provision for loan losses of $801 for the year then ended. 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 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Business and Organization CNB Financial Corporation (the “Corporation”) is headquartered in Clearfield, Pennsylvania, and provides a full range of banking and related services through its wholly owned subsidiary, CNB Bank (the “Bank”). In addition, the Bank provides trust and asset management services, including the administration of trusts and estates, retirement plans, and other employee benefit plans as well as a full range of wealth management services. The Bank serves individual and corporate customers and is subject to competition from other financial institutions and intermediaries with respect to these services. In addition to the Bank, the Corporation also operates a consumer discount loan and finance business through its wholly owned subsidiary, Holiday Financial Services Corporation (“Holiday”). The Corporation and these and its other subsidiaries are subject to examination by federal and state regulators. The Corporation’s market area is primarily concentrated in the central and northwest regions of the Commonwealth of Pennsylvania and in the central region of the state of Ohio.
Basis of Financial Presentation	Basis of Financial Presentation The financial statements are consolidated to include the accounts of the Corporation and the Bank, CNB Securities Corporation, Holiday, and CNB Insurance Agency. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
Use of Estimates	Use of Estimates To prepare financial statements in conformity with accounting principles generally accepted in the U.S., management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Operating Segments	Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Corporation-wide basis, and operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Interest Bearing Time Deposits with Other Banks	Interest Bearing Time Deposits with Other Banks Interest-bearing time deposits in other financial institutions mature within one year and are carried at cost.
Securities	Securities When purchased, securities are classified as held to maturity, trading or available for sale. Debt securities are classified as held to maturity when the Corporation has the positive intent and ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost. Debt or equity securities are classified as trading when purchased principally for the purpose of selling them in the near term, or when the fair value option has been elected. Trading securities are recorded at fair value with changes in fair value included in earnings in non-interest income. Available for sale securities are those securities not classified as held to maturity or trading and are carried at their fair value. Unrealized gains and losses, net of deferred tax, on securities classified as available for sale are recorded as other comprehensive income. Management has not classified any debt securities as held to maturity. The amortized cost of debt securities classified as held to maturity or available for sale is adjusted for the amortization of premiums and the accretion of discounts over the period through contractual maturity or, in the case of mortgage-backed securities and collateralized mortgage obligations, over the estimated life of the security. Such amortization is included in interest income from securities. Gains and losses on securities sold are recorded on the trade date and based on the specific identification method. Declines in the fair value of debt securities below their cost that are other than temporary and attributable to credit losses are reflected in earnings. Other-than-temporary impairment losses that are not attributable to credit losses are reported as a component of accumulated other comprehensive income. In estimating other-than-temporary losses, management considers: the length of time and extent that fair value has been less than cost, the financial condition and near term prospects of the issuer, and the Corporation’s intent to sell, or whether it is more likely than not that it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. If the Corporation intends to sell a security or it is more likely than not it will be required to sell a security before recovery of its amortized cost basis, the entire difference between amortized cost and fair value is recognized as impairment through earnings.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Interest income on commercial, industrial, and agricultural loans, commercial mortgage loans, and residential real estate loans is discontinued at the time the loan is 90 days delinquent unless the credit is well-secured and in process of collection. Consumer loans are typically charged off no later than 180 days past due. Past due status is based on the contractual terms of the loan. Loans, including loans modified in a troubled debt restructuring, are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received on loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. For all portfolio segments, loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Concentration of Credit Risk	Concentration of Credit Risk Most of the Corporation’s business activity is with customers located within the Commonwealth of Pennsylvania and the state of Ohio. Therefore, the Corporation’s exposure to credit risk is significantly affected by changes in the economies of Pennsylvania and Ohio.
Purchased Loans	Purchased Loans The Corporation purchased loans in connection with its acquisition of FC Banc Corp. in 2013, some of which had, at the acquisition date, shown evidence of credit deterioration since origination. These purchased credit impaired loans were recorded at the amount paid, such that there was no carryover of the seller’s allowance for loan losses. Further losses on purchased credit impaired loans are recognized by an increase in the allowance for loan losses. Such purchased credit impaired loans are accounted for individually, and the Corporation estimates the amount and timing of expected cash flows for each loan. The expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan’s contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a loss is recorded. If the present value of the expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. For loans purchased that did not show evidence of credit deterioration, the difference between the fair value of the loan at the acquisition date and the loan’s face value is being amortized as a yield adjustment over the estimated remaining life of the loan using the effective interest method.
Loans Held for Sale	Loans Held for Sale Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of the mortgage loan sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance account. Management determines the adequacy of the allowance based on historical patterns of charge-offs and recoveries, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, industry experience, economic conditions, and other qualitative factors relevant to the collectability of the loan portfolio. While management believes that the allowance is adequate to absorb probable loan losses incurred at the balance sheet date, future adjustments may be necessary due to circumstances that differ substantially from the assumptions used in evaluating the adequacy of the allowance for loan losses. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that the Corporation will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Commercial and commercial real estate loans are individually evaluated for impairment. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. Troubled debt restructurings are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component of the allowance for loan losses covers non-impaired The following portfolio segments, which are the same as the Corporation’s portfolio classifications and associated risk characteristics, have been identified: ● Commercial, industrial, and agricultural – risk characteristics include below average economic and employment conditions in many of the markets served by the Corporation, which has limited consumer spending. ● Commercial mortgages – the most significant risk characteristic is the subjectivity involved in real estate valuations for properties located in areas with low growth economies. ● Residential real estate – risk characteristics include slightly higher than historical levels of delinquencies and less than robust housing markets. ● Consumer – risk characteristics include continuing weakness in industrial employment in many of the markets served by the Corporation and low wage growth. ● Credit cards – the most significant risk characteristic is the unsecured nature of credit card loans. ● Overdrafts – risk characteristics include the Corporation’s continued deposit growth and overall economic conditions which may lead to a greater likelihood of overdrawn deposit accounts.
Federal Home Loan Bank (FHLB) Stock	Federal Home Loan Bank (FHLB) Stock As a member of the Federal Home Loan Bank of Pittsburgh (“FHLB”), the Corporation is required to purchase and hold stock in the FHLB to satisfy membership and borrowing requirements. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is unlike other investment securities insofar as there is no trading market for FHLB stock and the transfer price is determined by FHLB membership rules and not by market participants. FHLB stock is held as a long-term investment, is valued at its cost basis and is analyzed for impairment based on the ultimate recoverability of the par value. The Company evaluates impairment quarterly. The decision of whether impairment exists is a matter of judgment that reflects our view of the FHLB’s long-term performance, which includes factors such as the following: ● its operating performance; ● the severity and duration of declines in the fair value of its net assets related to its capital stock amount; ● its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; ● the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of FHLB; and ● its liquidity and funding position.
Premises and Equipment	Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation. Depreciation of premises and equipment is computed principally by the straight line method. In general, useful lives range from 3 to 39 years with lives for furniture, fixtures and equipment ranging from 3 to 10 years and lives of buildings and building improvements ranging from 15 to 39 years. Amortization of leasehold improvements is computed using the straight-line method over useful lives of the leasehold improvements or the term of the lease, whichever is shorter. Maintenance, repairs and minor renewals are charged to expense as incurred.
Foreclosed Assets	Foreclosed Assets Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at the lower of cost or fair value, less estimated costs to sell. If fair value declines, a valuation allowance is recorded through expense. Costs after acquisition are expensed.
Bank Owned Life Insurance	Bank Owned Life Insurance The Corporation has purchased life insurance policies on certain key employees. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate an impairment test should be performed. The Corporation has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives. Goodwill is the only intangible asset with an indefinite life on the Corporation’s balance sheet. Other intangible assets consist of a core deposit intangible asset arising from the acquisition of FC Banc Corp. in 2013. The core deposit intangible asset is amortized using an accelerated method over its estimated useful life of 7 years.
Long-Term Assets	Long-term Assets Premises and equipment, goodwill and other intangible assets, and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Derivatives	Derivatives Derivative financial instruments are recognized as assets or liabilities at fair value. The Corporation has interest rate swap agreements which are used as part of its asset liability management to help manage interest rate risk. The Corporation does not use derivatives for trading purposes. At the inception of a derivative contract, the Corporation designates the derivative as one of three types based on the purpose of the contract and belief as to its effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Corporation formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Corporation also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Corporation discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Advertising Costs	Advertising Costs Advertising costs are generally expensed as incurred and amounted to $1,580, $1,455, and $939, for 2015, 2014 and 2013, respectively.
Mortgage Servicing Rights	Mortgage Servicing Rights Servicing rights are recognized separately when they are acquired through sales of loans. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Corporation compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with mortgage banking income on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is reported on the income statement as mortgage banking income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material.
Treasury Stock	Treasury Stock The purchase of the Corporation’s common stock is recorded at cost. Purchases of the stock are made both in the open market and through negotiated private purchases based on market prices. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on a first-in-first-out basis.
Stock-Based Compensation	Stock-Based 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 up to 500,000 shares of common stock to be awarded in the form of nonqualified options or restricted stock. For key employees, the plan vesting schedule is one-fourth of granted stock-based awards per year beginning one year after the grant date with 100% vested on the fourth anniversary. For independent directors, the vesting schedule is one-third of granted stock-based awards per year beginning one year after the grant date with 100% vested on the third anniversary. At December 31, 2015 and 2014, there was no unrecognized compensation cost related to nonvested stock options granted under this plan, and no stock options were granted during the years ended December 31, 2015, 2014 and 2013. During 2015, 2014 and 2013, the Executive Compensation and Personnel Committee of the Board of Directors granted a total of 48,300, 35,400 and 31,500 shares, respectively, of restricted common stock to certain key employees and all independent directors of the Corporation. Compensation expense for the restricted stock awards is recognized over the requisite service period based on the fair value of the shares at the date of grant on a straight-line basis. Unearned restricted stock awards are recorded as a reduction of shareholders’ equity until earned. Compensation expense resulting from these restricted stock awards was $621, $548 and $390 for the years ended December 31, 2015, 2014 and 2013, respectively.
Comprehensive Income	Comprehensive Income The Corporation presents comprehensive income as part of the Consolidated Statement of Income and Comprehensive Income. Other comprehensive income (loss) consists of unrealized holding gains (losses) on the available for sale securities portfolio, changes in the unrecognized actuarial gain and transition obligation related to the Corporation’s post retirement benefits plans, and changes in the fair value of the Corporation’s interest rate swaps.
Income Taxes	Income Taxes The Corporation files a consolidated U.S. income tax return that includes all subsidiaries. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense.
Retirement Plans	Retirement Plans The Corporation’s expense associated with its 401(k) plan is determined under the provisions of the plan document and includes both matching and profit sharing components. Deferred compensation and supplemental retirement plan expenses allocate the benefits over years of service.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income available to common shareholders 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. 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 non-vested stock awards are participating securities.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of the consolidated statement of cash flows, the Corporation defines cash and cash equivalents as cash and due from banks, interest bearing deposits with other banks, and Federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing time deposits with other banks and borrowings with original maturities of 90 days or less.
Restrictions on Cash	Restrictions on Cash The Bank is required to maintain average reserve balances with the Federal Reserve Bank or in vault cash. The average amount of these non-interest bearing reserve balances for the year ended December 31, 2015 and 2014, was $50, which was maintained in vault cash. Note 12 to the consolidated financial statements discloses the cash collateral balances required to be maintained in connection with the Corporation’s interest rate swaps.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Adoption of New Accounting Standards	Adoption of New Accounting Standards 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 adoption of ASU 2014-04 did not have a material effect on the Corporation’s financial statements. In August 2014, the FASB issued Accounting Standards Update 2014-14, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure.” ASU 2014-14 amended existing guidance related to the classification of certain government-guaranteed mortgage loans, including those guaranteed by the FHA and the VA, upon foreclosure. It requires that a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if certain conditions are met. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of ASU 2014-14 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 this ASU 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. The accounting changes are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, with all other disclosure requirements required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The adoption of this guidance as of January 1, 2015 did not have an impact on the Corporation’s consolidated financial statements.
Effect of Newly Issued But Not Yet Effective Accounting Standards	Effect of Newly Issued But Not Yet Effective Accounting Standards 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. 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 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. 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.
