SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization The Corporation, through its wholly-owned subsidiaries, the Bank and CFS, provides a wide range of banking, financing, fiduciary and other financial services to its clients. The Corporation and the Bank are subject to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. CRM, a wholly-owned subsidiary of the Corporation, which was formed and began operations on May 31, 2016, is a Nevada-based captive insurance company which insures against certain risks unique to the operations of the Corporation and its subsidiaries and for which insurance may not be currently available or economically feasible in today's insurance marketplace. CRM pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. CRM is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Exchange Act. These financial statements include the accounts of the Corporation and its subsidiaries, and all significant intercompany balances and transactions are eliminated in consolidation. Amounts in the prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current period's presentation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures necessary for the fair presentation of the accompanying consolidated financial statements have been included. The unaudited consolidated financial statements should be read in conjunction with the Corporation's 2017 Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year or any other period. Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders' equity. Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . ASU 2016-02 requires companies that lease valuable assets to recognize on their balance sheets the assets and liabilities generated by contracts longer than a year. The amendments in this update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, though early adoption is permitted. The Corporation intends to adopt the new lease guidance as of January 1, 2019 and is currently evaluating the impact that adoption of these updates will have on its consolidated financial statements. Currently, the Corporation believes the implementation of this ASU will create a right of use asset of less than $15.0 million for the Corporation's 16 leased facilities and a related capital obligation of the same amount as of January 1, 2019. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The objective of the ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2019, though entities may adopt the amendments earlier for fiscal years beginning after December 15, 2018. The Corporation is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements. The Corporation anticipates that the adoption of the CECL model will result in an increase to the Corporation's allowance for loan losses. The Corporation has established a committee to oversee the implementation of CECL and has selected a vendor to assist in the implementation process. In 2018 the committee plans to begin establishing parameters which will be used in the CECL model with the selected vendor. The Corporation further plans to run its current incurred loss model and a CECL model concurrently for twelve months prior to the adoption of this guidance on January 1, 2020. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The objective of the ASU is to simplify the manner in which an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Additionally, the ASU removes the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails such qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for annual, or any interim, goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of the ASU is not expected to have a significant impact on the Corporation's consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The objective of the ASU is to align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. The amendment requires that the premium be amortized to the earliest call date, but does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this ASU are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. The adoption of the ASU is not expected to have a significant impact on the Corporation's consolidated financial statements. Adoption of New Accounting Standards On January 1, 2018, the Corporation adopted ASU 2016-01, an amendment to Recognition and Measurement of Financial Assets and Financial Liabilities ("ASC 825"). The objectives of the ASC 825 were (1) require equity investments to be measured at fair value, with changes in fair value recognized in net income, (2) simplify the impairment assessment of equity investments without readily determinable fair values, (3) eliminate the requirement to disclose methods and significant assumptions used to estimate fair value for financial instruments measured at amortized cost on the balance sheet, (4) require the use of the exit price notion when measuring the fair value of financial instruments, and (5) clarify the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. On January 1, 2018, the Corporation adopted ASU 2017-07, Compensation - Retirement Benefits - Improving the Presentation of Net Periodic Cost and Net Periodic Postretirement Benefit Cost ("ASC 715"). The objective of ASC 715 was to improve guidance related to the presentation of defined benefit costs in the income statement. Specifically, ASC 715 required that an employer report the service cost component in the same line item(s) as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, ASC 715 allows only the service cost component to be eligible for capitalization, when applicable. Results for reporting periods beginning after January 1, 2018 are presented under ASC 715, while prior period amounts continue to be reported in accordance with legacy GAAP, with comparable periods presented retrospectively for the presentation of the service cost and net periodic postretirement benefit cost in the income statement. The Corporation elected the practical expedient, which permits employers to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation for applying retrospective presentation requirements.

Earnings Per Share [Abstract]
EARNING PER COMMON SHARE	EARNING PER COMMON SHARE (shares in thousands) Basic earnings per share is net income divided by the weighted average number of common shares outstanding during the period. Issuable shares, including those related to directors’ restricted stock units and directors’ stock compensation, are considered outstanding and are included in the computation of basic earnings per share. All outstanding unvested share based payment awards that contain rights to non-forfeitable dividends are considered participating securities for this calculation. Restricted stock awards are grants of participating securities and are considered outstanding at grant date. Earnings per share information is adjusted to present comparative results for stock splits and stock dividends that occur. Earnings per share were computed by dividing net income by 4,834 and 4,802 weighted average shares outstanding for the three-month periods ended September 30, 2018 and 2017 , respectively. Earnings per share were computed by dividing net income by 4,828 and 4,796 weighted average shares outstanding for the nine - month periods ended September 30, 2018 and 2017 , respectively. There were no common stock equivalents during the three and nine -month periods ended September 30, 2018 or 2017 .

At September 30, 2018 , all of the unrealized losses related to mortgage-backed securities were issued by U.S. government sponsored entities, Fannie Mae and Freddie Mac. Because the decline in fair value is attributable to changes in interest rates and not credit quality, and because it is not likely that the Corporation will be required to sell these securities before their anticipated recovery, the Corporation does not consider these securities to be other-than-temporarily impaired at September 30, 2018 . Equity Investments Beginning January 1, 2018, upon adoption of ASU 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in the consolidated statement of income. For periods prior to adoption, equity investments were classified as available-for-sale and stated at fair value with unrealized gains and losses reports as a separate component of accumulated other comprehensive income, net of tax. The Corporation recognized a change in fair value of equity investments of $2.1 million during the three and nine month period ending September 30, 2018, primarily related to the sale of Visa Class B shares during the third quarter of 2018.

The Corporation offers various types of modifications which may involve a change in the schedule of payments, a reduction in the interest rate, an extension of the maturity date, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, requesting additional collateral, releasing collateral for consideration, substituting or adding a new borrower or guarantor, a permanent reduction of the recorded investment in the loan or a permanent reduction of the interest on the loan. As of September 30, 2018 and December 31, 2017 , the Corporation has a recorded investment in TDRs of $6.6 million and $7.7 million , respectively. There were specific reserves of $0.5 million and $0.7 million allocated for TDRs at September 30, 2018 and December 31, 2017 , respectively. As of September 30, 2018 , TDRs totaling $0.9 million were accruing interest under the modified terms and $5.7 million were on non-accrual status. As of December 31, 2017 , TDRs totaling $1.7 million were accruing interest under the modified terms and $6.0 million were on non-accrual status. The Corporation had committed no additional amounts as of both September 30, 2018 and December 31, 2017 , to customers with outstanding loans that are classified as TDRs. There were no loans modified as TDRs during the three month period ended September 30, 2018 while the terms of certain loans were modified as TDRs during the three month period ended September 30, 2017. The modification of the terms of two commercial and industrial term loans during the three months ended September 30, 2017 included a reduction of the schedule amortized payments for greater than a three month period, the release of collateral related to one of the loans, and the extension of a maturity date. During the nine months ended September 30, 2018 and 2017 , the terms of certain loans were modified as TDRs. The modification of the terms of one commercial and industrial term loan during the nine months ended September 30, 2018 included an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk. In addition to the modification noted above, the modification of two commercial and industrial term loans and one line of credit during the nine months ended September 30, 2017 included consolidating the loans into one commercial and industrial loan, extending the maturity date by approximately two years, and lowering the monthly payment. An additional piece of equipment was taken as collateral, but was not considered to be of greater value than the concession given. The modification of the terms of one commercial mortgage loan during the nine months ended September 30, 2017 included a reduction of the scheduled amortized payments of the loan for greater than a three month period. The modification of the terms of a residential mortgage loan during the nine months ended September 30, 2017 included an extension of the maturity date by approximately five years and a postponement of the scheduled amortized past due payments to the end of the loan. The following table presents loans by class modified as TDRs that occurred during the three month period ended September 30, 2017 (dollars in thousands): September 30, 2017 Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled debt restructurings: Commercial and agricultural: Commercial and industrial 2 $ 506 $ 506 Total 2 $ 506 $ 506 The TDRs described above increased the allowance for loan losses by $0.1 million and resulted in no charge-offs during the three month period ended September 30, 2017 .

The TDRs described above increased the allowance for loan losses by $0.2 million and resulted in no charge-offs during the nine months ended September 30, 2017. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no payment defaults on any loans previously modified as TDRs within twelve months following the modification during the three and nine month periods ended September 30, 2018 and 2017 . Credit Quality Indicators The Corporation establishes a risk rating at origination for all commercial loans. The main factors considered in assigning risk ratings include, but are not limited to: historic and future debt service coverage, collateral position, operating performance, liquidity, leverage, payment history, management ability, and the customer’s industry. Commercial relationship managers monitor all loans in their respective portfolios for any changes in the borrower’s ability to service its debt and affirm the risk ratings for the loans at least annually. For the retail loans, which include residential mortgages, indirect and direct consumer loans, home equity lines and loans, and credit cards, once a loan is properly approved and closed, the Corporation evaluates credit quality based upon loan repayment. The Corporation uses the risk rating system to identify criticized and classified loans. Commercial relationships within the criticized and classified risk ratings are analyzed quarterly. The Corporation uses the following definitions for criticized and classified loans (which are consistent with regulatory guidelines): 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 the institution’s credit position at some future date. Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capability 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 institution 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.

FAIR VALUE

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Fair value is the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be 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 reporting entity's own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Corporation used the following methods and significant assumptions to estimate fair value on a recurring basis: Available for Sale Securities: The fair values of securities available for sale are usually determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs), or matrix pricing, which is a mathematical technique widely used to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3 inputs). Equity Investments: Securities that are held to fund a deferred compensation plan and securities that have a readily determinable fair market value, are recorded at fair value with changes in fair value included in earnings. The fair values of equity investments are determined by quoted market prices (Level 1 inputs). Impaired Loans : At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value have been partially charged-off or receive specific allocations as part of the allowance for loan loss accounting. For collateral dependent loans, fair value is commonly based on real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, typically resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. OREO : Assets acquired through or instead of loan foreclosures are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Appraisals for both collateral-dependent impaired loans and OREO are performed by certified general appraisers (commercial properties) or certified residential appraisers (residential properties) whose qualifications and licenses have been reviewed and verified by the Corporation. Once received, appraisals are reviewed for reasonableness of assumptions, approaches utilized, Uniform Standards of Professional Appraisal Practice and other regulatory compliance, as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Appraisals are generally completed within the previous 12 month period prior to a property being placed into OREO. On impaired loans, appraisal values are adjusted based on the age of the appraisal, the position of the lien, the type of the property and its condition. Derivatives : The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date (Level 2 inputs). Derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices, and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The Corporation also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counter-party's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation has considered the impact of any applicable credit enhancements, such as collateral postings. Although the Corporation has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize credit default rate assumptions (Level 3 inputs).

Disclosure of Repurchase Agreements [Abstract]
SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE	SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE The Corporation enters into sales of securities under agreements to repurchase and the amounts received under these agreements represent borrowings and are reflected as a liability in the consolidated balance sheets. The securities underlying these agreements are included in investment securities in the consolidated balance sheets. The Corporation has no control over the market value of the securities which fluctuate due to market conditions, however, the Corporation is obligated to promptly transfer additional securities if the market value of the securities falls below the repurchase agreement price. The Corporation manages this risk by utilizing highly marketable and easily priced securities, monitoring these securities for significant changes in market valuation routinely, and maintaining an unpledged securities portfolio believed to be sufficient to cover a decline in the market value of the securities sold under agreements to repurchase. There were no securities sold under agreements to repurchase as of September 30, 2018 . A summary of securities sold under agreements to repurchase as of December 31, 2017 is as follows (in thousands): December 31, 2017 Overnight and Continuous Up to 1 Year 1 - 3 Years 3+ Years Total Mortgage-backed securities, residential $ — $ 11,798 $ — $ — $ 11,798 Excess collateral held — (1,798 ) — — (1,798 ) Gross amount of recognized liabilities for repurchase agreements $ — $ 10,000 $ — $ — $ 10,000

In accordance with GAAP, these financial instruments are not recorded in the financial statements. The Corporation's policy is to record such instruments when funded. These transactions involve, to varying degrees, elements of credit, interest rate and liquidity risk. Such transactions are generally used by the Corporation to manage clients' requests for funding and other client needs. The following table lists the contractual amounts of financial instruments with off-balance sheet risk at September 30, 2018 and December 31, 2017 (in thousands): September 30, 2018 December 31, 2017 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 14,516 $ 26,544 $ 16,019 $ 28,591 Unused lines of credit 1,246 202,355 1,604 200,353 Standby letters of credit — 15,627 — 15,022 On June 15, 2018, the Bank, through mediation, reached a resolution by way of a settlement agreement in the matter of Fane v. Chemung Canal Trust Company (the “Action”). The parties agreed to release each other from any and all liabilities, claims, counterclaims, demands, charges, complaints and causes of action, to dismiss the Action with prejudice, and the Bank agreed to pay Fane $3.3 million in connection with the settlement of the Action. As of March 31, 2018, the Corporation had a legal reserve of $2.3 million for the Action and therefore recognized an additional $1.0 million of legal expense during the second quarter of 2018. In the normal course of business, there are various outstanding claims and legal proceedings involving the Corporation or its subsidiaries. As of September 30, 2018 , we believe that we are not a party to any pending legal, arbitration, or regulatory proceedings that could have a material adverse impact on our financial results or liquidity.

The following tables present the Corporation's non-interest income by revenue stream and reportable segment for the three and nine months ended September 30, 2018 and 2017 (in thousands). Items outside the scope of ASC 606 are noted as such.

(c) The Holding Company, CFS, and CRM column above includes amounts to eliminate transactions between segments. A description of the Corporation's revenue streams accounted for under ASC 606 follows: Service Charges on Deposit Accounts: The Corporation earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which included services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are recognized at the time the maintenance occurs. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Interchange Income from Debit Card Transactions: The Corporation earns interchange fees from debit cardholder transactions conducted through the Mastercard payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to cardholder. WMG Fee Income (Gross): The Corporation earns wealth management fees from its contracts with trust customers to manage assets for investment, and/or to conduct transactions on their accounts. These fees are primarily earned over time as the Corporation provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management (AUM) at quarter-end. CFS Fee and Commission Income (Net): The Corporation earns fees from investment brokerage services provided to its customers by a third-party service provider. The Corporation receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The Corporation (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers. Investment brokerage fees are presented net of related costs. The Corporation also earns fees from tax services provided to its customers. Net Gains/Losses on Sales of OREO: The Corporation records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Corporation finances the sale of OREO to the buyer, the Corporation assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Corporation adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Corporation manages its operations through two primary business segments: core banking and WMG. The core banking segment provides revenues by attracting deposits from the general public and using such funds to originate consumer, commercial, commercial real estate, and residential mortgage loans, primarily in the Corporation’s local markets, and to invest in securities. The WMG services segment provides revenues by providing trust and investment advisory services to clients. Accounting policies for the segments are the same as those described in Note 1 of the Corporation’s 2017 Annual Report on Form 10-K, which was filed with the SEC on March 8, 2018. Summarized financial information concerning the Corporation’s reportable segments and the reconciliation to the Corporation’s consolidated results are shown in the following table. Income taxes are allocated based on the separate taxable income of each entity and indirect overhead expenses are allocated based on reasonable and equitable allocations applicable to the reportable segment. The Holding Company, CFS, and CRM column below includes amounts to eliminate transactions between segments (in thousands). Three months ended September 30, 2018 Core Banking WMG Holding Company, CFS, and CRM Consolidated Totals Interest and dividend income $ 16,122 $ — $ 14 $ 16,136 Interest expense 1,057 — — 1,057 Net interest income 15,065 — 14 15,079 Provision for loan losses 300 — — 300 Net interest income after provision for loan losses 14,765 — 14 14,779 Other non-interest income 4,987 2,406 (12 ) 7,381 Other non-interest expenses 11,871 1,307 250 13,428 Income (loss) before income tax expense (benefit) 7,881 1,099 (248 ) 8,732 Income tax expense (benefit) 1,555 281 (34 ) 1,802 Segment net income (loss) $ 6,326 $ 818 $ (214 ) $ 6,930 Three months ended September 30, 2017 Core Banking WMG Holding Company, CFS, and CRM Consolidated Totals Interest and dividend income $ 15,487 $ — $ 10 $ 15,497 Interest expense 734 — — 734 Net interest income 14,753 — 10 14,763 Provision for loan losses 1,289 — — 1,289 Net interest income after provision for loan losses 13,464 — 10 13,474 Other non-interest income 2,989 2,147 30 5,166 Other non-interest expenses 11,651 1,370 255 13,276 Income (loss) before income tax expense (benefit) 4,802 777 (215 ) 5,364 Income tax expense (benefit) 1,457 295 (42 ) 1,710 Segment net income (loss) $ 3,345 $ 482 $ (173 ) $ 3,654 Nine months ended September 30, 2018 Core Banking WMG Holding Company, CFS, and CRM Consolidated Totals Interest and dividend income $ 47,645 $ — $ 29 $ 47,674 Interest expense 2,678 — — 2,678 Net interest income 44,967 — 29 44,996 Provision for loan losses 3,371 — — 3,371 Net interest income after provision for loan losses 41,596 — 29 41,625 Other non-interest income 10,992 7,095 94 18,181 Legal settlements 989 — — 989 Other non-interest expenses 36,300 4,414 858 41,572 Income (loss) before income tax expense (benefit) 15,299 2,681 (735 ) 17,245 Income tax expense (benefit) 2,791 684 (126 ) 3,349 Segment net income (loss) $ 12,508 $ 1,997 $ (609 ) $ 13,896 Segment assets $ 1,740,311 $ 3,800 $ 9,753 $ 1,753,864 Nine months ended September 30, 2017 Core Banking WMG Holding Company, CFS, and CRM Consolidated Totals Interest and dividend income $ 44,478 $ — $ 17 $ 44,495 Interest expense 2,288 — — 2,288 Net interest income 42,190 — 17 42,207 Provision for loan losses 2,750 — — 2,750 Net interest income after provision for loan losses 39,440 — 17 39,457 Other non-interest income 8,228 6,525 282 15,035 Legal accruals and settlements 850 — — 850 Other non-interest expenses 34,795 4,142 866 39,803 Income (loss) before income tax expense (benefit) 12,023 2,383 (567 ) 13,839 Income tax expense (benefit) 3,523 904 (177 ) 4,250 Segment net income (loss) $ 8,500 $ 1,479 $ (390 ) $ 9,589 Segment assets $ 1,721,571 $ 4,112 $ 5,999 $ 1,731,682

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK COMPENSATION	STOCK COMPENSATION Board of Directors' Stock Compensation Pursuant to the Corporation's Directors' Compensation Plan, members of the Board of Directors receive common shares of the Corporation equal in value to the amount of fees individually earned during the previous year for service as a director. The common shares are distributed to the Corporation's individual board members from treasury shares of the Corporation on or about January 15 following the calendar year of service. Additionally, the Chief Executive Officer of the Corporation, who does not receive cash compensation as a member of the Board of Directors, is awarded common shares equal in value to the average of those awarded to board members not employed by the Corporation who have served for 12 months during the prior year. During January 2018 and 2017 , 6,015 and 7,880 shares, respectively, were re-issued from treasury to fund the stock component of directors' compensation. An expense of $86 thousand and $68 thousand related to this compensation was recognized during the three month periods ended September 30, 2018 and 2017 , respectively. An expense of $271 thousand and $222 thousand related to this compensation was recognized during the nine month periods ended September 30, 2018 and 2017 , respectively. This expense is accrued as shares are earned. Restricted Stock Plan Pursuant to the Corporation’s Restricted Stock Plan, the Corporation may make discretionary grants of restricted stock to officers other than the Corporation's Chief Executive Officer. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at issue date. A summary of restricted stock activity for the three month period ended September 30, 2018 is presented below: Shares Weighted–Average Grant Date Fair Value Nonvested at July 1, 2018 23,084 $ 37.88 Granted — — Vested — — Forfeited or cancelled — — Nonvested at September 30, 2018 23,084 $ 37.88 A summary of restricted stock activity for the nine month period ended September 30, 2018 is presented below: Shares Weighted–Average Grant Date Fair Value Nonvested at January 1, 2018 25,522 $ 38.01 Granted — — Vested (2,438 ) 39.28 Forfeited or cancelled — — Nonvested at September 30, 2018 23,084 $ 37.88 As of September 30, 2018 , there was $654 thousand of total unrecognized compensation cost related to nonvested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 3.08 years. The total fair value of shares vested was $112 thousand and $16 thousand for the nine month periods ended September 30, 2018 and 2017 , respectively.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2018
Accounting Policies [Abstract]
Organization	Organization The Corporation, through its wholly-owned subsidiaries, the Bank and CFS, provides a wide range of banking, financing, fiduciary and other financial services to its clients. The Corporation and the Bank are subject to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory authorities. CRM, a wholly-owned subsidiary of the Corporation, which was formed and began operations on May 31, 2016, is a Nevada-based captive insurance company which insures against certain risks unique to the operations of the Corporation and its subsidiaries and for which insurance may not be currently available or economically feasible in today's insurance marketplace. CRM pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. CRM is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Exchange Act. These financial statements include the accounts of the Corporation and its subsidiaries, and all significant intercompany balances and transactions are eliminated in consolidation. Amounts in the prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current period's presentation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures necessary for the fair presentation of the accompanying consolidated financial statements have been included. The unaudited consolidated financial statements should be read in conjunction with the Corporation's 2017 Annual Report on Form 10-K for the year ended December 31, 2017. The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year or any other period.
Reclassifications	Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders' equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) . ASU 2016-02 requires companies that lease valuable assets to recognize on their balance sheets the assets and liabilities generated by contracts longer than a year. The amendments in this update are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018, though early adoption is permitted. The Corporation intends to adopt the new lease guidance as of January 1, 2019 and is currently evaluating the impact that adoption of these updates will have on its consolidated financial statements. Currently, the Corporation believes the implementation of this ASU will create a right of use asset of less than $15.0 million for the Corporation's 16 leased facilities and a related capital obligation of the same amount as of January 1, 2019. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The objective of the ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to form credit loss estimates. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2019, though entities may adopt the amendments earlier for fiscal years beginning after December 15, 2018. The Corporation is currently evaluating the impact of the adoption of this guidance on its consolidated financial statements. The Corporation anticipates that the adoption of the CECL model will result in an increase to the Corporation's allowance for loan losses. The Corporation has established a committee to oversee the implementation of CECL and has selected a vendor to assist in the implementation process. In 2018 the committee plans to begin establishing parameters which will be used in the CECL model with the selected vendor. The Corporation further plans to run its current incurred loss model and a CECL model concurrently for twelve months prior to the adoption of this guidance on January 1, 2020. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The objective of the ASU is to simplify the manner in which an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Additionally, the ASU removes the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails such qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for annual, or any interim, goodwill impairment tests in fiscal years beginning after December 15, 2019. The adoption of the ASU is not expected to have a significant impact on the Corporation's consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . The objective of the ASU is to align the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities. The amendment requires that the premium be amortized to the earliest call date, but does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this ASU are effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018. The adoption of the ASU is not expected to have a significant impact on the Corporation's consolidated financial statements. Adoption of New Accounting Standards On January 1, 2018, the Corporation adopted ASU 2016-01, an amendment to Recognition and Measurement of Financial Assets and Financial Liabilities ("ASC 825"). The objectives of the ASC 825 were (1) require equity investments to be measured at fair value, with changes in fair value recognized in net income, (2) simplify the impairment assessment of equity investments without readily determinable fair values, (3) eliminate the requirement to disclose methods and significant assumptions used to estimate fair value for financial instruments measured at amortized cost on the balance sheet, (4) require the use of the exit price notion when measuring the fair value of financial instruments, and (5) clarify the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. On January 1, 2018, the Corporation adopted ASU 2017-07, Compensation - Retirement Benefits - Improving the Presentation of Net Periodic Cost and Net Periodic Postretirement Benefit Cost ("ASC 715"). The objective of ASC 715 was to improve guidance related to the presentation of defined benefit costs in the income statement. Specifically, ASC 715 required that an employer report the service cost component in the same line item(s) as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, ASC 715 allows only the service cost component to be eligible for capitalization, when applicable. Results for reporting periods beginning after January 1, 2018 are presented under ASC 715, while prior period amounts continue to be reported in accordance with legacy GAAP, with comparable periods presented retrospectively for the presentation of the service cost and net periodic postretirement benefit cost in the income statement. The Corporation elected the practical expedient, which permits employers to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation for applying retrospective presentation requirements.
Earnings Per Common Share	Basic earnings per share is net income divided by the weighted average number of common shares outstanding during the period. Issuable shares, including those related to directors’ restricted stock units and directors’ stock compensation, are considered outstanding and are included in the computation of basic earnings per share. All outstanding unvested share based payment awards that contain rights to non-forfeitable dividends are considered participating securities for this calculation. Restricted stock awards are grants of participating securities and are considered outstanding at grant date. Earnings per share information is adjusted to present comparative results for stock splits and stock dividends that occur.
Fair Value Measurement	Fair value is the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be 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 reporting entity's own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Corporation used the following methods and significant assumptions to estimate fair value on a recurring basis: Available for Sale Securities: The fair values of securities available for sale are usually determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs), or matrix pricing, which is a mathematical technique widely used to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3 inputs). Equity Investments: Securities that are held to fund a deferred compensation plan and securities that have a readily determinable fair market value, are recorded at fair value with changes in fair value included in earnings. The fair values of equity investments are determined by quoted market prices (Level 1 inputs). Impaired Loans : At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value have been partially charged-off or receive specific allocations as part of the allowance for loan loss accounting. For collateral dependent loans, fair value is commonly based on real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, typically resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. OREO : Assets acquired through or instead of loan foreclosures are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. 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 independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Appraisals for both collateral-dependent impaired loans and OREO are performed by certified general appraisers (commercial properties) or certified residential appraisers (residential properties) whose qualifications and licenses have been reviewed and verified by the Corporation. Once received, appraisals are reviewed for reasonableness of assumptions, approaches utilized, Uniform Standards of Professional Appraisal Practice and other regulatory compliance, as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Appraisals are generally completed within the previous 12 month period prior to a property being placed into OREO. On impaired loans, appraisal values are adjusted based on the age of the appraisal, the position of the lien, the type of the property and its condition. Derivatives : The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date (Level 2 inputs). Derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices, and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The Corporation also incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counter-party's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation has considered the impact of any applicable credit enhancements, such as collateral postings. Although the Corporation has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize credit default rate assumptions (Level 3 inputs).
