SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2016
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 Group, Inc., provides a wide range of banking, financing, fiduciary and other financial services to its clients. The Corporation is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory agencies. 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 consolidated financial statements have been prepared in conformity with GAAP and include the accounts of the Corporation and its subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. 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. CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash and amounts due from banks and demand interest-bearing deposits with other financial institutions. Time deposits with other financial institutions are classified as held-to-maturity securities and are not included in cash and cash equivalents. TRADING ASSETS Securities that are held to fund a non-qualified deferred compensation plan are recorded at fair value with changes in fair value and interest and dividend income included in earnings. SECURITIES Management determines the appropriate classification of securities at the time of purchase. If management has the intent and the Corporation has the ability at the time of purchase to hold securities until maturity, they are classified as held to maturity and carried at amortized cost. Securities to be held for indefinite periods of time or not intended to be held to maturity are classified as available for sale and carried at fair value. Unrealized holding gains and losses on securities classified as available for sale are excluded from earnings and are reported as accumulated other comprehensive income (loss) in shareholders' equity, net of the related tax effects, until realized. Realized gains and losses are determined using the specific identification method. Management evaluates securities for OTTI on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or 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 either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. In order to determine OTTI for purchased beneficial interests that, on the purchase date, were not highly rated, the Corporation compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment of yield using the interest method. Dividend and interest income is recognized when collected. FEDERAL HOME LOAN BANK AND FEDERAL RESERVE BANK STOCK The Bank is a member of both the FHLBNY and the FRBNY. FHLBNY members are required to own a certain amount of stock based on the level of borrowings and other factors, while FRBNY members are required to own a certain amount of stock based on a percentage of the Bank’s capital stock and surplus. FHLBNY and FRBNY stock are carried at cost and classified as non-marketable equities and periodically evaluated for impairment based on ultimate recovery of par value. Cash dividends are reported as income. LOANS Loans are stated at the amount of unpaid principal balance net of deferred loan fees. Additionally, recorded investment in loans includes interest receivable on loans. The Corporation has the ability and intent to hold its loans for the foreseeable future. The Corporation’s loan portfolio is comprised of the following segments: (i) commercial and agricultural, (ii) commercial mortgages, (iii) residential mortgages, and (iv) consumer loans. Commercial and agricultural loans primarily consist of loans to small to mid-sized businesses in the Corporation’s market area in a diverse range of industries. These loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Commercial mortgage loans are generally non-owner occupied commercial properties or owner occupied commercial real estate with larger balances. Repayment of these loans is often dependent upon the successful operation and management of the properties and the businesses occupying the properties, as well as on the collateral securing the loan. Residential mortgage loans are generally made on the basis of the borrower’s ability to make repayment from their employment and other income, but are secured by real property. Consumer loans include home equity lines of credit and home equity loans, which exhibit many of the same characteristics as residential mortgages. Indirect and other consumer loans are typically secured by depreciable assets, such as automobiles or boats, and are dependent on the borrower’s continuing financial stability. Interest on loans is accrued and credited to operations using the interest method. Past due status is based on the contractual terms of the loan. The accrual of interest is generally discontinued and previously accrued interest is reversed when loans become 90 days delinquent. Loans may also be placed on non-accrual status if management believes such classification is otherwise warranted. All payments received on non-accrual loans are applied to principal. Loans are returned to accrual status when they become current as to principal and interest and remain current for a period of six consecutive months or when, in the opinion of management, the Corporation expects to receive all of its original principal and interest. Loan origination fees and certain direct loan origination costs are deferred and amortized over the life of the loan as an adjustment to yield, using the interest method. Purchased Credit Impaired Loans: Loans acquired that show evidence of credit deterioration since origination are considered purchased credit impaired loans These loans are recorded at the fair value of the amount paid, such that there is no carryover of the seller’s allowance for loan losses. Such purchased loans are accounted for individually. The Corporation estimates the amount and timing of expected cash flows for each purchased loan and the expected cash flows in excess of 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). After acquisition, losses are recognized by an increase in the allowance for loan losses. 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 reserve is established. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. These loans are charged against the allowance for loan losses when management believes that the collectability of all or a portion of the principal is unlikely. The Corporation did not acquire any purchase credit impaired loans during the years ended December 31, 2016 and 2015. TROUBLED DEBT RESTRUCTURINGS A TDR is a formally renegotiated loan in which the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that would not have been granted to the borrower otherwise. Not all loans that are restructured as a TDR are classified as non-accrual before the restructuring occurs. Restructured loans can convert from non-accrual to accrual status when said loans have demonstrated performance, generally evidenced by six months of payment performance in accordance with the restructured terms and when, in the opinion of management, the Corporation expects to receive all of its contractual principal and interest due under the restructured terms. TDRs are individually evaluated for impairment and included in the separately identified impairment disclosures. TDRs are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For TDRs that subsequently default, the Company determines the amount of the allowance on that loan in accordance with the accounting policy for the allowance for loan losses on loans individually identified as impaired. The Company incorporates recent historical experience related to TDRs, including the performance of TDRs that subsequently default, into the calculation of the allowance by loan portfolio segment. ALLOWANCE FOR LOAN LOSSES The allowance is an amount that management believes will be adequate to absorb probable incurred losses on existing loans. The allowance is established based on management’s evaluation of the probable incurred losses in our portfolio in accordance with GAAP, and is comprised of both specific valuation allowances and general valuation allowances. A loan is classified as impaired when, based on current information and events, it is probable that the Corporation will be unable to collect both the principal and interest due under the contractual terms of the loan agreement. Specific valuation allowances are established based on management’s analyses of individually impaired loans. Factors considered by management in determining impairment include payment status, evaluations of the underlying collateral, expected cash flows, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is determined to be impaired and is placed on nonaccrual status, all future payments received are applied to principal and 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. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. Loans not impaired but classified as substandard and special mention use a historical loss factor on a rolling five year history of net losses. For all other unclassified loans, the historical loss experience is determined by portfolio class and is based on the actual loss history experienced by the Corporation over the most recent two years . This actual loss experience is supplemented with other qualitative factors based on the risks present for each portfolio class. These qualitative factors include consideration of the following: (1) lending policies and procedures, including underwriting standards and collection, charge-off and recovery policies, (2) national and local economic and business conditions and developments, including the condition of various market segments, (3) loan profiles and volume of the portfolio, (4)the experience, ability, and depth of lending management and staff, (5) the volume and severity of past due, classified and watch-list loans, non-accrual loans, troubled debt restructurings, and other modifications (6) the quality of the Bank’s loan review system and the degree of oversight by the Bank’s Board of Directors, (7) collateral related issues: secured vs. unsecured, type, declining valuation environment and trend of other related factors, (8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations, (9) the effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank’s current portfolio and (10) the impact of the global economy. The allowance for loan losses is increased through a provision for loan losses charged to operations. Loans are charged against the allowance for loan losses when management believes that the collectability of all or a portion of the principal is unlikely. Management's evaluation of the adequacy of the allowance for loan losses is performed on a periodic basis and takes into consideration such factors as the credit risk grade assigned to the loan, historical loan loss experience and review of specific impaired loans. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. LOANS HELD FOR SALE Certain mortgage loans are originated with the intent to sell. The Corporation typically retains the right to service the mortgages upon sale. Loans held for sale are recorded at the lower of cost or fair value in the aggregate and are regularly evaluated for changes in fair value. Commitments to sell the loans that are originated for sale are recorded at fair value. If necessary, a valuation allowance is established with a charge to income for unrealized losses attributable to a change in market rates. CAPITAL LEASES Capital leases are recorded at the lesser of the present value of future cash outlays using a discounted cash flow, or fair value at the beginning of the lease term. Initially, the capital lease is recorded as a building asset, which is depreciated over the shorter of the term of the lease or the estimated life of the asset, and a corresponding long term lease obligation, which amortizes as payments are made toward the lease. Interest expense is also incurred using the discount rate determined at the beginning of the lease term. PREMISES AND EQUIPMENT Land is carried at cost, while buildings, equipment, leasehold improvements and furniture are stated at cost less accumulated depreciation and amortization. Depreciation is charged to current operations under the straight-line method over the estimated useful lives of the assets, which range from 15 to 50 years for buildings and from 3 to 10 years for equipment and furniture. Amortization of leasehold improvements and leased equipment is recognized on the straight-line method over the shorter of the lease term or the estimated life of the asset. Leases of branch offices, which have been capitalized, are included within buildings and depreciated on the straight-line method over the shorter of the lease term or the estimated life of the asset. BANK OWNED LIFE INSURANCE BOLI is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the cash surrender value are recorded in other income. OTHER REAL ESTATE Real estate acquired through foreclosure or deed in lieu of foreclosure is recorded at estimated fair value of the property less estimated costs to dispose at the time of acquisition to establish a new carrying value. Write downs from the carrying value of the loan to estimated fair value which are required at the time of foreclosure are charged to the allowance for loan losses. Subsequent adjustments to the carrying values of such properties resulting from declines in fair value are charged to operations in the period in which the declines occur. INCOME TAXES The Corporation files a consolidated tax return. Deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for unused tax loss carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates to apply to taxable income in the years in which temporary differences are expected to be recovered or settled, or the tax loss carry forwards are expected to be utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. 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. WEALTH MANAGEMENT GROUP FEE INCOME Assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheets, since such assets are not assets of the Corporation. Wealth Management Group income is recognized on the accrual method as earned based on contractual rates applied to the balances of individual trust accounts. The unaudited market value of trust assets under administration total $1.721 billion , including $299.0 million of assets held under management or administration for the Corporation, at December 31, 2016 and $1.856 billion , including $304.1 million of assets held under management or administration for the Corporation, at December 31, 2015 . POSTRETIREMENT BENEFITS Pension Plan: The Chemung Canal Trust Company Pension Plan is a non-contributory defined benefit pension plan. The Pension Plan is a “qualified plan” under the IRS Code and therefore must be funded. Contributions are deposited to the Plan and held in trust. The Plan assets may only be used to pay retirement benefits and eligible plan expenses. The plan was amended such that new employees hired on or after July 1, 2010 would not be eligible to participate in the plan, however, existing participants at that time would continue to accrue benefits. Under the Plan, pension benefits are based upon final average annual compensation where the annual compensation is total base earnings paid plus 401(k) salary deferrals. Bonuses, overtime, commissions and dividends are excluded. The normal retirement benefit equals 1.2% of final average compensation (highest consecutive five years of annual compensation in the prior ten years ) times years of service (up to a maximum of 25 years ), plus 1% of average monthly compensation for each additional year of service (up to a maximum of 10 years ), plus 0.65% of average monthly compensation in excess of covered compensation for each year of credited service up to 35 years . Covered compensation is the average of the social security taxable wage bases in effect for the 35 year period prior to normal social security retirement age. Compensation for purposes of determining benefits under the Plan is reviewed annually. On October 20, 2016, the Corporation amended its noncontributory defined benefit pension plan (“pension plan”) to freeze future retirement benefits after December 31, 2016. Beginning on January 1, 2017, both the pay-based and service-based component of the formula used to determine retirement benefits in the pension plan were frozen so that participants will no longer earn further retirement benefits. The effects of this freeze are reflected in the pension plan disclosures as of December 31, 2016. See Note 12. Defined Contribution Profit Sharing, Savings and Investment Plan: The Corporation also sponsors a 401(K) defined contribution profit sharing, savings and investment plan which covers all eligible employees with a minimum of 1000 hours of annual service. The Corporation makes non-discretionary contributions and discretionary matching and profit sharing contributions to the plan based on the financial results of the Corporation. The plan's assets consist of Chemung Financial Corporation common stock, as well as other common and preferred stocks, U.S. Government securities, corporate bonds and notes, and mutual funds. The plan’s expense is the amount of non-discretionary contributions and discretionary matching and profit sharing contributions, and is charged to other operating expenses in the consolidated statements of income. Due to the freezing of the pension plan, the Corporation amended its defined contribution profit sharing, savings, and investment plan (“401(k)”) for all active participants to supersede the current contribution formula used by the Corporation. Beginning on January 1, 2017 the Corporation will begin contributing a non-discretionary 3% of gross annual wages (as defined by the 401(k) plan) for each participant, regardless of the participant’s deferral, in addition to a 50% match up to 6% of gross annual wages. All new contributions made on or after January 1, 2017 will vest immediately. Defined Benefit Health Care Plan: The Corporation sponsors a defined benefit health care plan that provides postretirement medical benefits to employees who meet minimum age and service requirements. This plan was amended effective July 1, 2006. Prior to this amendment, all retirees age 55 or older were eligible for coverage under the Corporation's self-insured health care plan, contributing 40% of the cost of the coverage. Under the amended plan, coverage for Medicare eligible retirees who reside in the Central New York geographic area is provided under a group sponsored plan with Excellus BlueCross BlueShield called Medicare Blue PPO, with the retiree paying 100% of the premium. Excellus BlueCross BlueShield assumes full liability for the payment of health care benefits incurred after July 1, 2006. Current Medicare eligible retirees who reside outside of the Central New York geographic area were eligible for coverage under the Corporation's self insurance plan thru December 31, 2009, contributing 50% of the cost of coverage. Effective January 1, 2010, these out of area retirees were eligible for coverage under a Medicare Supplement Plan C administered by Excellus BlueCross BlueShield, contributing 50% of the premium. Current retirees between the ages of 55 and 65 , will continue to be eligible for coverage under the Corporation's self insured plan, contributing 50% of the cost of the coverage. Employees who retired after July 1, 2006, and become Medicare eligible will only have access to the Medicare Blue PPO plan. Additionally, effective July 1, 2006, dental benefits were eliminated for all retirees. The cost of the plan is based on actuarial computations of current and future benefits for employees, and is charged to other operating expenses in the consolidated statements of income. On October 20, 2016, the Corporation amended its defined benefit health care plan to not allow any new retirees into the plan, effective January 1, 2017. The effects of this freeze are reflected in the pension plan disclosures as of December 31, 2016. See Note 12. Executive Supplemental Pension Plan: U.S. laws place limitations on compensation amounts that may be included under the Pension Plan. The Executive Supplemental Pension Plan is provided to executives in order to produce total retirement benefits, as a percentage of compensation that is comparable to employees whose compensation is not restricted by the annual compensation limit. Pension amounts, which exceed the applicable Internal Revenue Service code limitations, will be paid under the Executive Supplemental Pension Plan. The Executive Supplemental Pension Plan is a “non-qualified plan” under the Internal Revenue Service Code. Contributions to the Plan are not held in trust; therefore, they may be subject to the claims of creditors in the event of bankruptcy or insolvency. When payments come due under the Plan, cash is distributed from general assets. The cost of the plan is based on actuarial computations of current and future benefits for executives, and is charged to other operating expense in the consolidated statements of income. Defined Contribution Supplemental Executive Retirement Plan: The Defined Contribution Supplemental Executive Retirement Plan is provided to certain executives to motivate and retain key management employees by providing a nonqualified retirement benefit that is payable at retirement, disability, death and certain other events. The Defined Contribution Supplemental Executive Retirement Plan will deliver a retirement benefit comparable to that received by other executive officers participating in the bank’s Defined Benefit Plan. The Supplemental Executive Retirement Plan is intended to be an unfunded plan maintained primarily for the purpose of providing deferred compensation benefits for a select group of management or highly compensated employees under Sections 201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974. The plan’s expense is the Corporation’s annual contribution plus interest credits. STOCK-BASED COMPENSATION Restricted Stock Plan: The Restricted Stock Plan is designed to align the interests of the Corporation’s executives and senior managers with the interests of the Corporation and its shareholders, to ensure the Corporation’s compensation practices are competitive and comparable with those of its peers, and to promote the retention of select management-level employees. Under the terms of the Plan, the Corporation may make discretionary grants of restricted shares of the Corporation’s common stock to or for the benefit of employees selected to participate in the Plan. Each officer of the Corporation, other than the Corporation’s chief executive officer, is eligible to participate in the Plan. Awards are based on the performance, responsibility and contributions of the employee and are targeted at an average of the peer group. The maximum number of shares of the Corporation’s common stock that may be awarded as restricted shares to Plan participants may not exceed 15,000 per calendar year. Twenty percent of the restricted stock awarded to a participant vests each year commencing with the first anniversary date of the award and is 100 percent vested on the fifth anniversary date. Except in the case of the participant’s death, disability, or in the event of a change in control, the participant’s unvested shares of unrestricted stock will be forfeited if the participant leaves the employment of the Corporation or the Bank, with or without cause, or if the participant retires prior to attainment of age 65 . The plan’s expense is recognized as compensation expense ratably over the vesting period for the fair value of the award, measured at the grant date. See Note 13 for more information regarding this Plan. Deferred Directors Fee Plan: A Deferred Directors Fee Plan for non-employee directors provides that directors may elect to defer receipt of all or any part of their fees. Deferrals are either credited with interest compounded quarterly at the Applicable Federal Rate for short-term debt instruments or converted to units, which appreciate or depreciate, as would an actual share of the Corporation’s common stock purchased on the deferral date. Cash deferrals will be paid into an interest bearing account and paid in cash. Units will be paid in shares of common stock. All directors’ fees are charged to other operating expense in the consolidated statements of income. Directors’ Compensation Plan: The purpose of the Directors’ Compensation Plan is to enable the Corporation to attract and retain persons of exceptional ability to serve as directors and stockholders in enhancing the value of the common stock of the Corporation. The Plan was originally established to provide for the cash payment of an annual retainer and fees to non-employee directors serving on the Board of Directors of the Corporation and the Bank. The Plan was subsequently amended to provide: (i) payment of additional compensation to each non-employee director in shares of the Corporation’s common stock in an amount equal to the total cash compensation earned by each non-employee director during the year for service on the Board of Directors of each of the Corporation and the Bank, and for each year of service thereafter, to be distributed from treasury shares in January of the following calendar year; and (ii) payment to the President and CEO of the Corporation and the Bank for his service on the Boards of Directors of the Corporation and the Bank in an amount equal in value to the average cash compensation awarded to non-employee directors who have served twelve (12) months of the previous year. The maximum number of shares of Corporation’s common stock that may be granted under the Plan may not exceed 20,000 per year. The Plan provides that the value of a share of common stock granted under the Plan shall be determined as the average of the closing prices of a share of common stock as quoted on the applicable established securities market for each of the prior 30 trading days ending on December 31 st of the calendar year. The cost of all cash and stock compensation is charged to other operating expenses in the consolidated statements of income. Incentive Compensation Plan: The purpose of the Incentive Compensation Plan is to attract and retain highly qualified officers and key employees, and to motivate such persons to serve the Corporation and the Bank and to expend maximum effort to improve the business results and earnings of the Corporation by providing to such persons an opportunity to acquire or increase a direct proprietary interest in the operations and future success of the Corporation. To this end, the Incentive Compensation Plan provides for the discretionary grant of cash and/or unrestricted stock, i.e., common stock of the Corporation that is free of any restrictions, such as restrictions on transferability, to select officers and key employees as designated by the Board of Directors in its sole discretion. The maximum number of shares that can be awarded as unrestricted stock under the Incentive Compensation Plan to any individual is 10,000 per calendar year; and the maximum amount that may be earned in cash as an Incentive Award in any calendar year by any individual is $300,000 . The right of any eligible employee to receive a grant of an incentive award, whether in the form of cash or unrestricted stock, is subject to performance standards that are specified by either the Compensation Committee or the Board of Directors. The cost of all cash and unrestricted stock compensation is charged to other operating expenses in the consolidated

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 December 31, 2016 , 2015 and 2014 , the Corporation has a recorded investment in TDRs of $10.2 million , $12.0 million , and $9.7 million , respectively. There were specific reserves of $0.9 million allocated for TDRs at December 31, 2016 , and $1.4 million allocated for December 31, 2015, and $0.3 million allocated for December 31, 2014 . As of December 31, 2016 , TDRs totaling $5.8 million were accruing interest under the modified terms and $4.4 million were on non-accrual status. As of December 31, 2015 , TDRs totaling $7.6 million were accruing interest under the modified terms and $4.4 million were on non-accrual status. As of December 31, 2014 , TDRs totaling $8.7 million were accruing interest under the modified terms and $1.0 million were on non-accrual status. The Corporation has committed no additional amounts as of December 31, 2016 to customers with outstanding loans that are classified as TDRs. The Corporation committed additional amounts totaling up to $0.1 million as of both December 31, 2015 and December 31, 2014 to customers with outstanding loans that are classified as TDRs. During the years ended December 31, 2016 , 2015 and 2014 , the terms of certain loans were modified as TDRs. During the year ended December 31, 2016, the modification of the terms of a residential mortgage loan included an extension of the maturity date by thirteen years at a stated interest rate lower than the current market rate for new debt with similar risk and a corresponding reduction of the scheduled amortization payments of the loan due to the longer term. Also, $8 thousand of closing costs were capitalized on the restructured loan. Additionally, the modification of the terms of five commercial real estate loans and one residential home equity loan included consolidating the loans into one commercial real estate loan and extending the maturity date at a stated interest rate lower than the current market rate for new debt with similar risk. Also the modification of the terms of a residential mortgage loan included a reduction in the stated interest rate for three years and a corresponding reduction of the scheduled amortized payments of the loan due to the lower interest rate. Additionally, $4 thousand of interest and past due escrow payments were capitalized on the restructured loan. The modification of the terms of another commercial real estate loan included a postponement or reduction of the scheduled amortized payments of the loan for greater than a 3 month period and a partial release of collateral due to a sale of property after which the bank received part of the proceeds to bring the loan current and reduce the principal balance with the remainder of the proceeds used to pay delinquent taxes. This results in a reduction in outstanding principal of $97 thousand at the time of restructuring. The modification of the terms of such commercial loans performed during the year ended December 31, 2015 included renewing a line of credit and extending the maturity date at a rate lower than the current market rate, decreases of scheduled amortization payments for five loans and reductions of interest rates for two loans. The modification of the terms of such commercial loans performed during the year ended December 31, 2014 included a permanent reduction of the recorded investment and a change in the schedule of payments for one loan and renewing lines of credit or loans and extending maturity dates at rates lower than the current market rates for six other loans. The modification of the terms of the residential mortgage loan included extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk. The modification of the terms of the home equity line of credit included a change in the schedule of payments and extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk.

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 troubled debt restructurings during the year ended December 31, 2016 within twelve months following the modification. The following table presents loans by class modified as TDRs for which there was a payment default within twelve months following the modification during the year ended December 31, 2015 : December 31, 2015 Number of Loans Recorded Investment Commercial mortgages: Commercial mortgages 2 $ 1,877 Total 2 $ 1,877 The TDRs that subsequently defaulted described above did not increase the allowance for loan losses and resulted in no charge offs during the year ended December 31, 2015. There were no payment defaults on any loans previously modified as troubled debt restructurings during the year ended December 31, 2014 within twelve months following the modification. 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 their 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. Retail loans are not rated until they become 90 days past due. 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 as 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. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Loans listed as not rated are included in groups of homogeneous loans. Based on the analyses performed as of December 31, 2016 and December 31, 2015 , the risk category of the recorded investment of loans by class of loans is as follows (in thousands): December 31, 2016 Not Rated Pass Loans Special Mention Substandard Doubtful Total Commercial and agricultural: Commercial and industrial $ — $ 172,873 $ — $ 2,277 $ 1,516 $ — $ 176,666 Agricultural — 361 — — — — 361 Commercial mortgages: Construction — 45,055 — 259 1,196 — 46,510 Commercial mortgages — 496,723 1,323 8,574 15,566 1,460 523,646 Residential mortgages 194,669 — 95 — 4,201 — 198,965 Consumer loans Credit cards 1,476 — — — — — 1,476 Home equity lines and loans 97,183 — — — 1,670 — 98,853 Indirect consumer loans 139,339 — — — 654 — 139,993 Direct consumer loans 16,967 — — — 45 — 17,012 Total $ 449,634 $ 715,012 $ 1,418 $ 11,110 $ 24,848 $ 1,460 $ 1,203,482 December 31, 2015 Not Rated Pass Loans Special Mention Substandard Doubtful Total Commercial and agricultural: Commercial and industrial $ — $ 186,359 $ — $ 3,772 $ 2,521 $ 9 $ 192,661 Agricultural — 1,039 — — — — 1,039 Commercial mortgages: Construction — 40,881 — 287 63 — 41,231 Commercial mortgages — 437,549 1,825 8,437 14,454 4,204 466,469 Residential mortgages 192,245 — 270 — 3,721 — 196,236 Consumer loans Credit cards 1,482 — — — — — 1,482 Home equity lines and loans 101,219 — — — 758 — 101,977 Indirect consumer loans 151,184 — — — 542 — 151,726 Direct consumer loans 18,639 — — — 43 — 18,682 Total $ 464,769 $ 665,828 $ 2,095 $ 12,496 $ 22,102 $ 4,213 $ 1,171,503 The Corporation considers the performance of the loan portfolio and its impact on the allowance for loan losses. For residential and consumer loan classes, the Corporation also evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. Non-performing loans include non-accrual loans and non-accrual troubled debt restructurings. The following table presents the recorded investment in residential and consumer loans based on payment activity as of December 31, 2016 and December 31, 2015 (in thousands): December 31, 2016 Consumer Loans Residential Mortgages Credit Card Home Equity Lines and Loans Indirect Consumer Loans Other Direct Consumer Loans Performing $ 194,764 $ 1,476 $ 97,183 $ 139,339 $ 16,967 Non-Performing 4,201 — 1,670 654 45 Total $ 198,965 $ 1,476 $ 98,853 $ 139,993 $ 17,012 December 31, 2015 Consumer Loans Residential Mortgages Credit Card Home Equity Lines and Loans Indirect Consumer Loans Other Direct Consumer Loans Performing $ 192,626 $ 1,482 $ 101,219 $ 151,184 $ 18,639 Non-Performing 3,610 — 758 542 43 Total $ 196,236 $ 1,482 $ 101,977 $ 151,726 $ 18,682 At the time of the merger with Fort Orange Financial Corp., the Corporation identified certain loans with evidence of deteriorated credit quality, and the probability that the Corporation would be unable to collect all contractually required payments from the borrower. These loans are classified as PCI loans. The Corporation adjusted its estimates of future expected losses, cash flows, and renewal assumptions on the PCI loans during the current year. These adjustments were made for changes in expected cash flows due to loans refinanced beyond original maturity dates, impairments recognized subsequent to the acquisition, advances made for taxes or insurance to protect collateral held and payments received in excess of amounts originally expected.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES As part of the Corporation's product offerings, the Corporation acts as an interest rate swap counterparty for certain commercial borrowers in the normal course of servicing our customers. The interest rate swap agreements are free-standing derivatives and are recorded at fair value in the Corporation's consolidated balance sheets. The Corporation manages its exposure to such interest rate swaps by entering into corresponding and offsetting interest rate swaps with third parties that mirror the terms of the interest rate swaps it has with the commercial borrowers. These positions directly offset each other and the Corporation's exposure is the fair value of the derivatives due to potential changes in credit risk of our commercial borrowers and third parties. The Corporation also enters into risk participation agreements with dealer banks on commercial loans in which it participates. The Corporation receives an upfront fee for participating in the credit exposure of the interest rate swap associated with the commercial loan in which it is a participant and the fee received is recognized immediately in other non-interest income. The Corporation is exposed to its share of the credit loss equal to the fair value of the interest rate swap in the event of nonperformance by the counterparty of the interest rate swap. The Corporation determines the fair value of the credit loss exposure using an estimated credit default rate based on the historical performance of similar assets. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. At December 31, 2016 , the Corporation held derivatives not designated as hedging instruments with a total notional amount of $52.2 million . Derivatives not designated as hedging instruments included back-to-back interest rate swaps of $36.8 million , consisting of $18.4 million of interest rate swaps with commercial borrowers and an additional $18.4 million of offsetting interest rate swaps with third-party counter-parties on substantially the same terms, and risk participation agreements with dealer banks of $15.4 million . Free-standing derivatives are not designated as hedges for accounting purposes and are therefore recorded at fair value with changes in fair value recorded in other non-interest income. The following table presents information regarding our derivative financial instruments, at December 31: 2016 Number of Instruments Notional Amount Weighted Average Maturity Weighted Average Interest Rate Received Weighted Average Contract Pay Rate Fair Value Other Assets/ (Other Liabilities) Derivatives not designated as hedging instruments: Interest rate swap agreements on loans with commercial loan customers 5 $ 18,378 7.9 4.05 % 3.36 % $ (693 ) Interest rate swap agreements with third-party counter-parties 5 18,378 7.9 3.36 % 4.05 % 693 Risk participation agreements 5 15,401 23.5 (68 ) Total 15 $ 52,157 $ (68 ) 2015 Number of Instruments Notional Amount Weighted Average Maturity Weighted Average Interest Rate Received Weighted Average Contract Pay Rate Fair Value Other Assets/ (Other Liabilities) Derivatives not designated as hedging instruments: Interest rate swap agreements on loans with commercial loan customers 1 $ 1,934 5.9 4.33 % 3.02 % $ 15 Interest rate swap agreements with third-party counter-parties 1 1,934 5.9 3.02 % 4.33 % (16 ) Risk participation agreements 4 10,528 26.2 (47 ) 6 $ 14,396 $ (48 ) 2014 Number of Instruments Notional Amount Weighted Average Maturity Weighted Average Interest Rate Received Weighted Average Contract Pay Rate Fair Value Other Assets/ (Other Liabilities) Derivatives not designated as hedging instruments: Risk participation agreements 3 $ 8,335 31.5 N/A N/A $ (18 ) 3 $ 8,335 $ (18 ) Off-balance sheet exposure for the risk participation agreements was $1.3 million and $0.9 million for December 31, 2016 and 2015 , respectively.

A valuation allowance is recognized when it is more likely than not that some portion of the deferred tax assets will not be realized. In assessing the need for a valuation allowance, management considers the scheduled reversal of the deferred tax assets, the level of historical taxable income and projected future taxable income over the periods in which the temporary differences comprising the deferred tax assets will be deductible. Based on its assessment, management determined that no valuation allowance is necessary. As of December 31, 2016 , 2015 and 2014 , the Corporation did not have any unrecognized tax benefits. The Corporation accounts for interest and penalties related to uncertain tax positions as part of its provision for Federal and State income taxes. As of December 31, 2016 , 2015 and 2014 , the Corporation did not accrue any interest or penalties related to its uncertain tax positions. The Corporation is not currently subject to examinations by Federal taxing authorities for the years prior to 2013 and for New York State taxing authorities for the years prior to 2013 .

Compensation and Retirement Disclosure [Abstract]
PENSION PLAN AND OTHER BENEFIT PLANS	PENSION PLAN AND OTHER BENEFIT PLANS Pension Plan The Corporation has a noncontributory defined benefit pension plan covering a majority of employees. The plan's defined benefit formula generally based payments to retired employees upon their length of service multiplied by a percentage of the average monthly pay over the last five years of employment. New employees hired on or after the July 10, 2010 were not eligible to participate in the plan, however, existing participants at that time continued to accrue benefits. On October 20, 2016, the Corporation amended its noncontributory defined benefit pension plan (“pension plan”) to freeze future retirement benefits after December 31, 2016. Beginning on January 1, 2017, both the pay-based and service-based component of the formula used to determine retirement benefits in the pension plan were frozen so that participants will no longer earn further retirement benefits. The Corporation uses a December 31 measurement date for its pension plan. The following table presents (1) changes in the plan's projected benefit obligation and plan assets, and (2) the plan's funded status at December 31, 2016 and 2015 (in thousands): Change in projected benefit obligation: 2016 2015 Benefit obligation at beginning of year $ 43,797 $ 45,544 Service cost 1,047 1,231 Interest cost 1,883 1,806 Actuarial (gain) loss 913 (3,199 ) Curtailments (6,161 ) — Benefits paid (1,688 ) (1,585 ) Benefit obligation at end of year $ 39,791 $ 43,797 Change in plan assets: 2016 2015 Fair value of plan assets at beginning of year $ 39,951 $ 43,336 Actual return on plan assets 3,297 (1,800 ) Employer contributions — — Benefits paid (1,688 ) (1,585 ) Fair value of plan assets at end of year $ 41,560 $ 39,951 Funded status $ 1,769 $ (3,846 ) Amount recognized in accumulated other comprehensive income (loss) at December 31, 2016 and 2015 consist of the following (in thousands): 2016 2015 Net actuarial loss $ 10,788 $ 17,863 Prior service cost — 7 Total before tax effects $ 10,788 $ 17,870 The accumulated benefit obligation at December 31, 2016 and 2015 was $39.8 million and $37.7 million , respectively. The principal actuarial assumptions used in determining the projected benefit obligation as of December 31, 2016 , 2015 and 2014 were as follows: 2016 2015 2014 Discount rate 4.16 % 4.39 % 4.09 % Assumed rate of future compensation increase N/A 5.00 % 5.00 % Components of net periodic benefit cost and other amounts recognized in other comprehensive income (loss) in 2016 , 2015 and 2014 consist of the following (in thousands): Net periodic benefit cost 2016 2015 2014 Service cost, benefits earned during the year $ 1,047 $ 1,231 $ 1,045 Interest cost on projected benefit obligation 1,883 1,806 1,738 Expected return on plan assets (3,019 ) (3,287 ) (3,174 ) Amortization of net loss 1,549 1,414 649 Amortization of prior service cost 7 7 7 Net periodic cost $ 1,467 $ 1,171 $ 265 Other changes in plan assets and benefit obligations recognized in other comprehensive income (loss): 2016 2015 2014 Net actuarial (gain) loss $ (5,526 ) $ 1,888 $ 8,195 Recognized loss (1,549 ) (1,414 ) (649 ) Amortization of prior service cost (7 ) (7 ) (7 ) Total recognized in other comprehensive income (loss) (before tax effect) $ (7,082 ) $ 467 $ 7,539 Total recognized in net benefit cost and other comprehensive income (loss) (before tax effect) $ (5,615 ) $ 1,638 $ 7,804 During 2016 the plan's total unrecognized net loss decreased by $7.1 million . Because the total unrecognized net gain or loss in the plan exceeds 10% of the projected benefit obligation or 10% of the plan assets, the excess will be amortized. Due to the plan freeze effective December 31, 2016, this excess will now be amortized over the average total life expectancy of all participants which was 28.49 years as of January 1, 2016. Prior to the plan freeze, the excess was amortized over the average future working lifetime of active participants which was 8.76 year as of January 1, 2016. Actual results for 2017 will depend on the 2017 actuarial valuation of the plan. Amounts expected to be recognized in net periodic cost during 2017 (in thousands): Loss recognition $ 233 Prior service cost recognition $ — The principal actuarial assumptions used in determining the net periodic benefit cost for the years ended December 31, 2016 , 2015 and 2014 were as follows: 2016 2015 2014 Discount rate 4.39 % 4.09 % 4.92 % Expected long-term rate of return on assets 7.75 % 7.75 % 7.75 % Assumed rate of future compensation increase 5.00 % 5.00 % 5.00 % The Corporation changes important assumptions whenever changing conditions warrant. At December 31, 2016, the Corporation used Retirement Plan 2014 (RP-2014) and Mortality Improvement Scale 2016 (MP-2016) as a basis for the Plan's valuation. At December 31, 2015, the Corporation used Retirement Plan 2014 (RP-2014) and Mortality Improvement Scale 2015 (MP-2015) as a basis for the Plan's valuation. The discount rate is evaluated at least annually and the expected long-term return on plan assets will typically be revised every three to five years, or as conditions warrant. Other material assumptions include the compensation increase rates, rates of employee terminations, and rates of participant mortality. The Corporation's overall investment strategy is to achieve a mix of investments for long-term growth and for near-term benefit payments with a wide diversification of asset types. The target allocations for plan assets are shown in the table below. Equity securities primarily include investments in common or preferred shares of both U.S. and international companies. Debt securities include U.S. Treasury and Government bonds as well as U.S. Corporate bonds. Other investments may consist of mutual funds, money market funds and cash & cash equivalents. While no significant changes in the asset allocations are expected during 2017 , the Corporation may make changes at any time. The expected return on plan assets was determined based on a CAPM using historical and expected future returns of the various asset classes, reflecting the target allocations described below. Asset Class Target Allocation 2016 Percentage of Plan Assets at December 31, Expected Long-Term Rate of Return 2016 2015 Large cap domestic equities 30% - 60% 57 % 58 % 10.3 % Mid-cap domestic equities 0% - 20% 5 % 4 % 10.6 % Small-cap domestic equities 0% - 15% 2 % 3 % 10.8 % International equities 0% - 25% 7 % 6 % 10.3 % Intermediate fixed income 20% - 50% 26 % 23 % 4.7 % Alternative assets 0% - 10% — % 2 % 7.5 % Cash 0% - 20% 3 % 4 % 2.5 % Total 100 % 100 % The investment policy of the plan is to provide for long-term growth of principal and income without undue exposure to risk. The focus is on long-term capital appreciation and income generation. The Corporation maintains an IPS that guides the investment allocation in the plan. The IPS describes the target asset allocation positions as shown in the table above. The Corporation has appointed an Employee Pension and Profit Sharing Committee to manage the general philosophy, objectives and process of the plan. The Employee Pension and Profit Sharing Committee meets with the Investment Manager periodically to review the plan's performance and to ensure that the current investment allocation is within the guidelines set forth in the IPS. Only the Employee Pension and Profit Sharing Committee, in consultation with the Investment Manager, can make adjustments to maintain target ranges and for any permanent changes to the IPS. Quarterly, the Board of Directors' Trust and Employee Benefits Committee reviews the performance of the plan with the Investment Manager. As of December 31, 2016 and 2015 , the Corporation's pension plan did not hold any direct investment in the Corporation's common stock. The Corporation used the following methods and significant assumptions to estimate the fair value of each type of financial instrument held by the pension plan: Fair value is the exchange price that would be received for an asset in the principal or most advantageous market for the asset in an orderly transaction between market participants on the measurement date. The fair value hierarchy described below requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). 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). Discounted cash flows are calculated using spread and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations. The fair value of the plan assets at December 31, 2016 and 2015 , by asset class are as follows (in thousands): Fair Value Measurement at Plan Assets Carrying Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Cash $ 1,324 $ 1,324 $ — $ — Equity securities: U.S. companies 19,972 19,972 — — International companies 847 847 — — Mutual funds 14,680 14,680 — — Debt securities: U.S. Treasuries/Government bonds 2,218 — 2,218 — U.S. Corporate bonds 2,519 — 2,519 — Total plan assets $ 41,560 $ 36,823 $ 4,737 $ — Fair Value Measurement at Plan Assets Carrying Value Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Cash $ 1,486 $ 1,486 $ — $ — Equity securities: U.S. companies 23,424 23,424 — — International companies 1,277 1,277 — — Mutual funds 8,548 8,548 — — Debt securities: U.S. Treasuries/Government bonds 2,468 — 2,468 — U.S. Corporate bonds 2,748 — 2,748 — Total plan assets $ 39,951 $ 34,735 $ 5,216 $ — The following table presents the estimated benefit payments for each of the next five years and the aggregate amount expected to be paid in years six through ten for the pension plan (in thousands): Calendar Year Future Expected Benefit Payments 2017 $ 2,055 2018 $ 2,106 2019 $ 2,150 2020 $ 2,176 2021 $ 2,213 2022-2026 $ 11,292 The Corporation does not expect to contribute to the plan during 2017 . Funding requirements for subsequent years are uncertain and will significantly depend on changes in assumptions used to calculate plan funding levels, the actual return on plan assets, changes in the employee groups covered by the plan, and any legislative or regulatory changes affecting plan funding requirements. For tax planning, financial planning, cash flow management or cost reduction purposes the Corporation may increase, accelerate, decrease or delay contributions to the plan to the extent permitted by law. Defined Contribution Profit Sharing, Savings and Investment Plan The Corporation also sponsors a defined contribution profit sharing, savings and investment plan which covers all eligible employees with a minimum of 1,000 hours of annual service. The Corporation makes discretionary matching and profit sharing contributions to the plan for employees hired prior to July 1, 2010 based on the financial results of the Corporation. The Corporation also contributes to a non-discretionary 401K plan which covers all eligible employees hired after July 1, 2010. Expense related to both plans totaled $609 thousand , $639 thousand , and $620 thousand for the years ended December 31, 2016 , 2015 and 2014 , respectively. The plan's assets at December 31, 2016 , 2015 and 2014 include 174,957 , 169,398 , and 170,714 shares, respectively, of Chemung Financial Corporation common stock, as well as other common and preferred stocks, U.S. Government securities, corporate bonds and notes, and mutual funds. Defined Benefit Health Care Plan On October 20, 2016, the Corporation amended its defined benefit health care plan to not allow any new retirees into the plan, effective January 1, 2017. The effects of this freeze are reflected in the defined benefit health care plan disclosures as of December 31, 2016. The Corporation uses a December 31 measurement date for its defined benefit health care plan. The following table presents (1) changes in the plan's accumulated postretirement benefit obligation and (2) the plan's funded status at December 31, 2016 and 2015 (in thousands): Changes in accumulated postretirement benefit obligation: 2016 2015 Accumulated postretirement benefit obligation - beginning of year $ 1,664 $ 1,663 Service cost 43 46 Interest cost 66 70 Participant contributions 87 83 Amendments (1,101 ) — Actuarial (gain) loss 138 215 Benefits paid (474 ) (413 ) Accumulated postretirement benefit obligation at end of year $ 423 $ 1,664 Change in plan assets: 2016 2015 Fair value of plan assets at beginning of year $ — $ — Employer contribution 387 330 Plan participants’ contributions 87 83 Benefits paid (474 ) (413 ) Fair value of plan assets at end of year $ — $ — Funded status $ (423 ) $ (1,664 ) Amount recognized in accumulated other comprehensive income (loss) at December 31, 2016 and 2015 consist of the following (in thousands): 2016 2015 Net actuarial loss $ 636 $ 517 Prior service credit (1,101 ) (434 ) Total before tax effects $ (465 ) $ 83 Weighted-average assumption for disclosure as of December 31: 2016 2015 2014 Discount rate 4.16 % 4.39 % 4.09 % Health care cost trend: Initial 6.50 % 7.00 % 7.00 % Health care cost trend: Ultimate 5.00 % 5.00 % 5.00 % Year ultimate cost trend reached 2020 2019 2018 The components of net periodic postretirement benefit cost for the years ended December 31, 2016 , 2015 and 2014 are as follows (in thousands): Net periodic cost (benefit) 2016 2015 2014 Service cost $ 43 $ 46 $ 39 Interest cost 66 70 72 Amortization of prior service benefit (97 ) (97 ) (97 ) Recognized actuarial loss 20 20 3 Recognized prior service benefit due to curtailments (337 ) — — Net periodic postretirement cost (benefit) $ (305 ) $ 39 $ 17 Other changes in plan assets and benefit obligations 2016 2015 2014 Net actuarial gain $ 139 $ 216 $ 177 Recognized actuarial loss (20 ) (20 ) (3 ) Prior service credit (1,101 ) — — Amortization of prior service benefit 434 97 97 Total recognized in other comprehensive income (loss)(before tax effect) $ (548 ) $ 293 $ 271 Total recognized in net benefit cost and other comprehensive income (loss) (before tax effect) $ (853 ) $ 332 $ 288 During 2016 the plan's total unrecognized net loss increased by $119 thousand . Because the total unrecognized net gain or loss in the plan exceeds 10% of the accumulated postretirement benefit obligation, the excess will be amortized over the average future working lifetime of active plan participants. As of January 1, 2016 , the average future working lifetime of active participants was 14.3 years. Since the plan was frozen as of December 31, 2016, the amortization period moved to the average future life expectancy of the remaining retirees, which at January 1, 2016 was 5.0 years. Actual results for 2017 will depend on the 2017 actuarial valuation of the plan. Amounts expected to be recognized in net periodic cost during 2017 (in thousands): Loss recognition $ 119 Prior service cost recognition $ (220 ) Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plan. A one-percentage point change in assumed health care cost trend rates would have the following effects (in thousands): Effect of a 1% increase in health care trend rate on: 2016 2015 2014 Benefit obligation $ 2 $ 3 $ 5 Total service and interest cost $ — $ — $ — Effect of a 1% decrease in health care trend rate on: 2016 2015 2014 Benefit obligation $ (3 ) $ (3 ) $ (6 ) Total service and interest cost $ — $ — $ — Weighted-average assumptions for net periodic cost as of December 31: 2016 2015 2014 Discount rate 4.39 % 4.09 % 4.92 % Health care cost trend: Initial 7.00 % 7.00 % 8.00 % Health care cost tread: Ultimate 5.00 % 5.00 % 5.00 % Year ultimate reached 2019 2018 2018 The following table presents the estimated benefit payments for each of the next five years and the aggregate amount expected to be paid in years six through ten (in thousands): Calendar Year Future Estimated Benefit Payments 2017 $ 115 2018 $ 104 2019 $ 71 2020 $ 49 2021 $ 27 2022-2026 $ 67 The Corporation’s policy is to contribute the amount required to fund postretirement benefits as they become due to retirees. The amount expected to be required in contributions to the plan during 2017 is $115 thousand . Executive Supplemental Pension Plan The Corporation also sponsors an Executive Supplemental Pension Plan for certain former executive officers to restore certain pension benefits that may be reduced due to limitations under the Internal Revenue Code. The benefits under this plan are unfunded as of December 31, 2016 and 2015 . The Corporation uses a December 31 measurement date for its Executive Supplemental Pension Plan. The following table presents Executive Supplemental Pension plan status at December 31, 2016 and 2015 (in thousands): Change in projected benefit obligation: 2016 2015 Benefit obligation at beginning of year $ 1,210 $ 1,244 Service cost 43 44 Interest cost 51 49 Actuarial (gain) loss 19 (52 ) Benefits paid (75 ) (75 ) Projected benefit obligation at end of year $ 1,248 $ 1,210 Changes in plan assets: 2016 2015 Fair value of plan assets at beginning of year $ — $ — Employer contributions 75 75 Benefits paid (75 ) (75 ) Fair value of plan assets at end of year $ — $ — Unfunded status $ (1,248 ) $ (1,210 ) Amounts recognized in accumulated other comprehensive income (loss) at December 31, 2016 and 2015 consist of the following (in thousands): 2016 2015 Net actuarial loss $ 165 $ 173 Prior service cost — — Total before tax effects $ 165 $ 173 Accumulated benefit obligation at December 31, 2016 and 2015 was $1.2 million .

Because the unrecognized net gain or loss exceeds the greater of 10% of the projected benefit obligation or 10% of the plan assets, the excess will be amortized. Due to the fact that the plan no longer has any active participants, this excess will now be amortized over the average total life expectancy of all participants which was 15.05 as of January 1, 2017. In prior years, the excess was amortized over the average future working lifetime of active participants which was 4.00 years as of January 1, 2017.

Corporation contributions are equal to the benefit payments to plan participants. Defined Contribution Supplemental Executive Retirement Plan The Corporation also sponsors a Defined Contribution Supplemental Executive Retirement Plan for certain current executive officers, which was initiated in 2012. The plan is unfunded as of December 31, 2016 and is intended to provide nonqualified deferred compensation benefits payable at retirement, disability, death or certain other events. The balance in the plan as of December 31, 2016 and 2015 was $1,043 thousand and $772 thousand , respectively. A total of $262 thousand , $231 thousand , and $213 thousand was expensed during the years ended December 31, 2016 , 2015 , and 2014 , respectively. In addition to each participants account being credited with the annual company contribution, each account will receive a quarterly interest credit that will equal the average yield on five year U.S. Treasury Notes.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK COMPENSATION	STOCK COMPENSATION Board of Director’s Stock Compensation 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 of Directors 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 of Directors members not employed by the Corporation who have served for 12 months during the prior year. During January 2017 , 2016 , and 2015 , 7,880 , 9,532 and 9,673 shares, respectively, were re-issued from treasury to fund the stock component of the directors' and the Chief Executive Officer’s compensation. An expense of $269 thousand , $262 thousand and $271 thousand related to this compensation was recognized during the years ended December 31, 2016 , 2015 and 2014 , respectively. This expense is accrued as shares are earned. Restricted Stock Plan Pursuant to the Corporation’s Restricted Stock Plan (the “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 as of December 31, 2016 , and changes during the year ended is presented below: Shares Weighted–Average Grant Date Fair Value Nonvested at December 31, 2015 22,569 $ 28.09 Granted 8,249 32.77 Vested (7,024 ) 27.45 Forfeited or Cancelled — — Nonvested at December 31, 2016 23,794 $ 29.90 As of December 31, 2016 , there was $693 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 3.76 years . The total fair value of shares vested during the years ended December 31, 2016 , 2015 and 2014 were $193 thousand , $314 thousand and $152 thousand , respectively.

In April 2016, the Bank moved its Clifton Park branch to 25 Park Avenue, Clifton Park, New York under a lease agreement through March 2036 from the same member of the Corporation's Board of Directors with monthly lease payments of $11 thousand . In October 2016, the property was sold to an unrelated third party, from which the Bank continues to lease the property. The Bank also leases from this Board of Directors member its branch located at 1365 New Scotland Road, Slingerlands, New York, under a lease agreement through August 2019 with monthly rent expense totaling $4 thousand per month. Annual rent paid to this Board of Directors member totaled $169 thousand , $90 thousand and $73 thousand for the years ended December 31, 2016, and 2015 and 2014, respectively. The Bank utilized legal services from a local law firm in which a member of the Board of Directors is a principal owner. Services totaled $36 thousand , $88 thousand and $67 thousand for the years ended December 31, 2016, 2015, and 2014, respectively. The Bank leases its branch located at 127 Court Street, Binghamton, New York under a lease agreement through June 2030 from an entity in whom the employer of a Director of the Corporation has a twenty percent interest.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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 amounts of financial instruments with off-balance sheet risk at year-end were as follows (in thousands): 2016 2015 Fixed Rate Variable Rate Fixed Rate Variable Rate Commitments to make loans $ 38,246 $ 33,189 $ 17,167 $ 25,251 Unused lines of credit $ 610 $ 208,124 $ 1,265 $ 177,004 Standby letters of credit $ — $ 14,241 $ — $ 14,646 Commitments to make real estate and home equity loans are generally made for periods of sixty days or less. As of December 31, 2016 , the fixed rate commitments to make loans have interest rates ranging from 2.75% to 5.25% and maturities ranging from five years to thirty years . Commitments to fund commercial draw notes are generally made for periods of three months to twenty-four months . As of December 31, 2016 , the fixed rate commitments have interest rates ranging from 4.05% to 4.70% . Because many commitments and almost all standby letters of credit expire without being funded in whole or in part, the contract amounts are not estimates of future cash flows. Loan commitments and unused lines of credit have off-balance sheet credit risk because only origination fees are recognized on the consolidated balance sheet until commitments are fulfilled or expire. The credit risk amounts are equal to the contractual amounts, assuming the amounts are fully advanced and collateral or other security is of no value. The Corporation does not anticipate losses as a result of these transactions. These commitments also have off-balance sheet interest rate risk in that the interest rate at which these commitments were made may not be at market rates on the date the commitments are fulfilled. The Corporation has issued conditional commitments in the form of standby letters of credit to guarantee payment on behalf of a customer and guarantee the performance of a customer to a third party. Standby letters of credit generally arise in connection with lending relationships. The credit risk involved in issuing these instruments is essentially the same as that involved in extending loans to customers. Contingent obligations under standby letters of credit totaled $14.2 million at December 31, 2016 and represent the maximum potential future payments the Corporation could be required to make. Typically, these instruments have terms of twelve months or less and expire unused; therefore, the total amounts do not necessarily represent future cash requirements. Each customer is evaluated individually for creditworthiness under the same underwriting standards used for commitments to extend credit and on-balance sheet instruments. Corporation policies governing loan collateral apply to standby letters of credit at the time of credit extension. The carrying amount and fair value of the Corporation's standby letters of credit at December 31, 2016 was not significant. On March 26, 2015, the New York Surrogate’s Court for Chemung County entered an order approving two stipulations that discontinued litigation against the WMG of the Bank and approved settlements of the litigations. Under the terms of the settlements, the Bank agreed to pay the two parties $12.1 million , in total. Payments for the two settlements, offset by $7.9 million of insurance proceeds, occurred during the second quarter of 2015. The Bank established a $4.3 million legal reserve in connection with this case during the third quarter of 2014. On March 23, 2016, the Bank received a summons and complaint for an action brought in the State of New York Supreme Court for the County of Tompkins, regarding its lease of 202 East State Street, Ithaca, NY. The owner of the leased premises has alleged that the Bank has breached its contract and is requesting a judgment declaring that the term of the lease runs through December 31, 2025 or a judgment in his favor in the amount of $4.0 million . On July 25, 2016, the Corporation received Notice of Entry of the decision and order of the New York Supreme Court for the County of Tompkins, involving claims by the owner of the leased premises at 202 East State Street, Ithaca, New York against the Bank. The Court granted, in part, partial summary judgment in favor of the plaintiff - on the issue of liability only- for anticipatory breach and breach of contract. The fraud claims were dismissed, and summary judgment was denied on the plaintiff’s trespass claims. The Court set the matter down for an inquest on damages at a later date, with the original claim by the plaintiff seeking $4.0 million in damages. The Corporation has filed an appeal to the court determination which has been perfected in the Appellate Devision, Third Department of State Supreme Court. The briefing process has not been completed, although the Record on Appeal and the Corporation's brief have both been filed with the Appellate Division. The Corporation established a legal reserve of $1.2 million in connection with this case during the second quarter of 2016, which the Corporation has deemed sufficient as of December 31, 2016. In the normal course of business, there are various outstanding claims and legal proceedings involving the Corporation or its subsidiaries. Except for the above matter, the Corporation believes that it is not a party to any pending legal, arbitration, or regulatory proceedings that could have a material adverse impact on its financial results or liquidity.

FAIR VALUES

FAIR VALUES	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUES	FAIR VALUES 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: Investment 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). Trading Assets: Securities that are held to fund a deferred compensation plan are recorded at fair value with changes in fair value included in earnings. The fair values of trading assets 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 credit risk participations are based on credit default rate assumptions (Level 3 inputs). Assets and liabilities measured at fair value on a recurring basis are summarized below (in thousands): Fair Value Measurement at December 31, 2016 Financial Assets: Fair Value Quoted Prices Significant Significant Unobservable Inputs Obligations of U.S. Government and U.S. $ 17,455 $ — $ 17,455 $ — Mortgage-backed securities, residential 245,866 — 245,866 — Obligations of states and political subdivisions 38,740 — 38,740 — Corporate bonds and notes 250 — — 250 SBA loan pools 570 — 570 — Corporate stocks 521 170 351 — Total available for sale securities $ 303,402 $ 170 $ 302,982 $ 250 Trading assets $ 774 $ 774 $ — $ — Derivative assets 693 — 693 — Financial Liabilities: Derivative liabilities $ 761 $ — $ 693 $ 68 Fair Value Measurement at December 31, 2015 Financial Assets: Fair Value Quoted Prices Significant Other Observable Inputs Significant Unobservable Inputs Obligations of U.S. Government and U.S. $ 100,166 $ 14,784 $ 85,382 $ — Mortgage-backed securities, residential 198,366 — 198,366 — Obligations of states and political subdivisions 44,426 — 44,426 — Corporate bonds and notes 752 — 504 248 SBA loan pools 647 — 647 — Corporate stocks 463 56 407 — Total available for sale securities $ 344,820 $ 14,840 $ 329,732 $ 248 Trading assets $ 701 $ 701 $ — $ — Derivative assets 15 — 15 — Financial Liabilities: Derivative liabilities $ 63 $ — $ 15 $ 48 During the year ended December 31, 2016 , the Corporation transferred corporate stocks with a fair market value of $158 thousand at the date of transfer (and $103 thousand at December 31, 2016) from Level 2 to Level 1 due to the corporation's stock becoming publicly listed. There were no transfers between Level 1 and Level 2 during the year ended December 31, 2015 . The significant unobservable inputs used in the fair value measurement of the Corporation’s collateralized mortgage obligations are probabilities of specific-issuer defaults and deferrals and specific-issuer recovery assumptions. Significant increases in specific-issuer default assumptions or decreases in specific-issuer recovery assumptions would result in a significantly lower fair value measurement. Conversely, decreases in specific-issuer default assumptions or increases in specific-issuer recovery assumptions would result in a higher fair value measurement. The Corporation treats all interest payment deferrals as defaults and assumes no recoveries on defaults.

FHLB and FRB Stock It is not practicable to determine the fair value of FHLBNY and FRBNY stock due to restrictions on its transferability. Loans Receivable For variable-rate loans that reprice frequently, fair values approximate carrying values. The fair values for other loans are estimated through discounted cash flow analysis using interest rates currently being offered for loans with similar terms and credit quality. Loans are classified as Level 3. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. Loans held for sale are classified as Level 2. Loans Held for Sale Certain mortgage loans are originated with the intent to sell. Loans held for sale are recorded at the lower of cost or fair value in the aggregate. Loans held for sale are classified as Level 2. Deposits The fair values disclosed for demand deposits, savings accounts and money market accounts are, by definition, equal to the amounts payable on demand at the reporting date (i.e., their carrying values) and classified as Level 1. The fair value of certificates of deposits is estimated using a discounted cash flow approach that applies interest rates currently being offered on certificates to a schedule of the weighted-average expected monthly maturities and classified as Level 2. Securities Sold Under Agreements to Repurchase These instruments bear both variable and fixed rates of interest. Therefore, the carrying value approximates fair value for the variable rate instruments and the fair value of fixed rate instruments is based on discounted cash flows to maturity. These are classified as Level 2. FHLBNY Term Advances These instruments bear a stated rate of interest to maturity and, therefore, the fair value is based on discounted cash flows to maturity and classified as Level 2. Commitments to Extend Credit The fair value of commitments to extend credit is based on fees currently charged to enter into similar agreements, the counter-party's credit standing and discounted cash flow analysis. The fair value of these commitments to extend credit approximates the recorded amounts of the related fees and is not material at December 31, 2016 and 2015 . Accrued Interest Receivable and Payable For these short-term instruments, the carrying value approximates fair value resulting in a classification of Level 1, Level 2 or Level 3 depending upon the classification of the asset/liability they are associated with. The carrying amounts and estimated fair values of other financial instruments, at December 31, 2016 and December 31, 2015 , are as follows (in thousands): Fair Value Measurements at Financial assets: Carrying Amount Quoted Prices Significant Other Observable Inputs Significant Unobservable Inputs Estimated Cash and due from financial $ 28,205 $ 28,205 $ — $ — $ 28,205 Interest-bearing deposits in other 45,957 45,957 — — 45,957 Trading assets 774 774 — — 774 Securities available for sale 303,402 170 302,982 250 303,402 Securities held to maturity 4,705 — 981 3,931 4,912 FHLBNY and FRBNY stock 4,041 — — — N/A Loans, net 1,186,037 — — 1,205,814 1,205,814 Loans held for sale 412 — 412 — 412 Accrued interest receivable 4,000 9 784 3,207 4,000 Derivative assets 693 — 693 — 693 Financial liabilities: Deposits: Demand, savings, and insured $ 1,312,237 $ 1,312,237 $ — $ — $ 1,312,237 Time deposits 144,106 — 144,460 — 144,460 Securities sold under agreements 27,606 — 27,880 — 27,880 FHLBNY term advances 9,093 — 9,189 — 9,189 Accrued interest payable 210 25 185 — 210 Derivative liabilities 761 — 693 68 761 (1) Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument.

REGULATORY CAPITAL REQUIREMENTS

REGULATORY CAPITAL REQUIREMENTS	12 Months Ended
	Dec. 31, 2016
Regulatory Capital Requirements [Abstract]
REGULATORY CAPITAL REQUIREMENTS	REGULATORY CAPITAL REQUIREMENTS The Corporation and the Bank are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action 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 initiate regulatory action. The final rules implementing Basel III rules became effective for the Corporation 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. Under Basel III rules, the Corporation must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in from 0.00% for 2015 to 2.50% by 2019. The capital conservation buffer for 2016 is 0.625% . The net unrealized gain or loss on available for sale securities and changes in the funded status of the defined benefit pension plan and other benefit plans are not included in computing regulatory capital. Management believes as of December 31, 2016, the Corporation and the Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to 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, and capital restoration plans are required. Management believes that, as of December 31, 2016 and 2015 , the Corporation and the Bank met all capital adequacy requirements to which they were subject. As of December 31, 2016 , the most recent notification from the Federal Reserve Bank of New York categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There have been no conditions or events since that notification that management believes have changed the Bank's or the Corporation's capital category. The Corporation’s principal source of funds for dividend payments is dividends received from the Bank. Banking regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s net income, combined with the retained net income of the preceding two years , subject to the capital requirements in the table below. During 2017 , the Bank could, without prior approval, declare dividends of approximately $15.2 million plus any 2017 net income retained to the date of the dividend declaration. The actual capital amounts and ratios of the Corporation and the Bank are presented in the following tables (in thousands): Actual Minimal Capital Adequacy Minimal Capital Adequacy with Capital Buffer To Be Well As of December 31, 2016 Amount Ratio Amount Ratio Amount Ratio Amount Ratio Total Capital (to Risk Weighted Assets): Consolidated $ 145,269 12.14 % $ 95,748 8.00 % $ 103,229 8.625 % N/A N/A Bank $ 140,020 11.71 % $ 95,640 8.00 % $ 103,112 8.625 % $ 119,550 10.00 % Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 130,911 10.94 % $ 71,811 6.00 % $ 79,292 6.625 % N/A N/A Bank $ 125,736 10.52 % $ 71,730 6.00 % $ 79,202 6.625 % $ 95,640 8.00 % Common Equity Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 130,911 10.94 % $ 53,858 4.50 % $ 61,339 5.125 % N/A N/A Bank $ 125,736 10.52 % $ 53,798 4.50 % $ 61,270 5.125 % $ 77,708 6.50 % Tier 1 Capital (to Average Assets): Consolidated $ 130,911 7.81 % $ 67,031 4.00 % N/A N/A N/A N/A Bank $ 125,736 7.52 % $ 66,919 4.00 % N/A N/A $ 83,649 5.00 % Actual Minimum Capital Adequacy To Be Well Capitalized Under Prompt Corrective Action Provisions As of December 31, 2015 Amount Ratio Amount Ratio Amount Ratio Total Capital (to Risk Weighted Assets): Consolidated $ 139,049 12.26 % $ 90,704 8.00 % N/A N/A Bank $ 135,058 11.93 % $ 90,548 8.00 % $ 113,185 10.00 % Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 124,787 11.01 % $ 68,028 6.00 % N/A N/A Bank $ 120,881 10.68 % $ 67,911 6.00 % $ 90,548 8.00 % Common Equity Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 124,787 11.01 % $ 51,021 4.50 % N/A N/A Bank $ 120,881 10.68 % $ 50,933 4.50 % $ 73,571 6.50 % Tier 1 Capital (to Average Assets): Consolidated $ 124,787 7.83 % $ 63,772 4.00 % N/A N/A Bank $ 120,881 7.59 % $ 63,701 4.00 % $ 79,626 5.00 %

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. 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. CFS amounts are the primary differences between segment amounts and consolidated totals, and are reflected in the Holding Company, CFS, and CRM column below, along with amounts to eliminate transactions between segments (in thousands). CRM was formed during the second quarter of 2016, therefore, is not included within prior year comparative information.

SUMMARY OF SIGNIFICANT ACCOUN29

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
ORGANIZATION	ORGANIZATION The Corporation, through its wholly owned subsidiaries, the Bank and CFS Group, Inc., provides a wide range of banking, financing, fiduciary and other financial services to its clients. The Corporation is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory agencies. 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 consolidated financial statements have been prepared in conformity with GAAP and include the accounts of the Corporation and its subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. 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.
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS Cash and cash equivalents include cash and amounts due from banks and demand interest-bearing deposits with other financial institutions. Time deposits with other financial institutions are classified as held-to-maturity securities and are not included in cash and cash equivalents.
TRADING ASSETS	TRADING ASSETS Securities that are held to fund a non-qualified deferred compensation plan are recorded at fair value with changes in fair value and interest and dividend income included in earnings.
SECURITIES	SECURITIES Management determines the appropriate classification of securities at the time of purchase. If management has the intent and the Corporation has the ability at the time of purchase to hold securities until maturity, they are classified as held to maturity and carried at amortized cost. Securities to be held for indefinite periods of time or not intended to be held to maturity are classified as available for sale and carried at fair value. Unrealized holding gains and losses on securities classified as available for sale are excluded from earnings and are reported as accumulated other comprehensive income (loss) in shareholders' equity, net of the related tax effects, until realized. Realized gains and losses are determined using the specific identification method. Management evaluates securities for OTTI on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or 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 either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. In order to determine OTTI for purchased beneficial interests that, on the purchase date, were not highly rated, the Corporation compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment of yield using the interest method. Dividend and interest income is recognized when collected.
FEDERAL HOME LOAN BANK AND FEDERAL RESERVE BANK STOCK	FEDERAL HOME LOAN BANK AND FEDERAL RESERVE BANK STOCK The Bank is a member of both the FHLBNY and the FRBNY. FHLBNY members are required to own a certain amount of stock based on the level of borrowings and other factors, while FRBNY members are required to own a certain amount of stock based on a percentage of the Bank’s capital stock and surplus. FHLBNY and FRBNY stock are carried at cost and classified as non-marketable equities and periodically evaluated for impairment based on ultimate recovery of par value. Cash dividends are reported as income.
LOANS	LOANS Loans are stated at the amount of unpaid principal balance net of deferred loan fees. Additionally, recorded investment in loans includes interest receivable on loans. The Corporation has the ability and intent to hold its loans for the foreseeable future. The Corporation’s loan portfolio is comprised of the following segments: (i) commercial and agricultural, (ii) commercial mortgages, (iii) residential mortgages, and (iv) consumer loans. Commercial and agricultural loans primarily consist of loans to small to mid-sized businesses in the Corporation’s market area in a diverse range of industries. These loans are typically made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Commercial mortgage loans are generally non-owner occupied commercial properties or owner occupied commercial real estate with larger balances. Repayment of these loans is often dependent upon the successful operation and management of the properties and the businesses occupying the properties, as well as on the collateral securing the loan. Residential mortgage loans are generally made on the basis of the borrower’s ability to make repayment from their employment and other income, but are secured by real property. Consumer loans include home equity lines of credit and home equity loans, which exhibit many of the same characteristics as residential mortgages. Indirect and other consumer loans are typically secured by depreciable assets, such as automobiles or boats, and are dependent on the borrower’s continuing financial stability. Interest on loans is accrued and credited to operations using the interest method. Past due status is based on the contractual terms of the loan. The accrual of interest is generally discontinued and previously accrued interest is reversed when loans become 90 days delinquent. Loans may also be placed on non-accrual status if management believes such classification is otherwise warranted. All payments received on non-accrual loans are applied to principal. Loans are returned to accrual status when they become current as to principal and interest and remain current for a period of six consecutive months or when, in the opinion of management, the Corporation expects to receive all of its original principal and interest. Loan origination fees and certain direct loan origination costs are deferred and amortized over the life of the loan as an adjustment to yield, using the interest method.
PURCHASE CREDIT IMPAIRED LOANS	Purchased Credit Impaired Loans: Loans acquired that show evidence of credit deterioration since origination are considered purchased credit impaired loans These loans are recorded at the fair value of the amount paid, such that there is no carryover of the seller’s allowance for loan losses. Such purchased loans are accounted for individually. The Corporation estimates the amount and timing of expected cash flows for each purchased loan and the expected cash flows in excess of 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). After acquisition, losses are recognized by an increase in the allowance for loan losses. 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 reserve is established. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. These loans are charged against the allowance for loan losses when management believes that the collectability of all or a portion of the principal is unlikely. The Corporation did not acquire any purchase credit impaired loans during the years ended December 31, 2016 and 2015.
TROUBLED DEBT RESTRUCTURINGS	TROUBLED DEBT RESTRUCTURINGS A TDR is a formally renegotiated loan in which the Bank, for economic or legal reasons related to a borrower’s financial difficulties, grants a concession to the borrower that would not have been granted to the borrower otherwise. Not all loans that are restructured as a TDR are classified as non-accrual before the restructuring occurs. Restructured loans can convert from non-accrual to accrual status when said loans have demonstrated performance, generally evidenced by six months of payment performance in accordance with the restructured terms and when, in the opinion of management, the Corporation expects to receive all of its contractual principal and interest due under the restructured terms. TDRs are individually evaluated for impairment and included in the separately identified impairment disclosures. TDRs are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For TDRs that subsequently default, the Company determines the amount of the allowance on that loan in accordance with the accounting policy for the allowance for loan losses on loans individually identified as impaired. The Company incorporates recent historical experience related to TDRs, including the performance of TDRs that subsequently default, into the calculation of the allowance by loan portfolio segment.
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES The allowance is an amount that management believes will be adequate to absorb probable incurred losses on existing loans. The allowance is established based on management’s evaluation of the probable incurred losses in our portfolio in accordance with GAAP, and is comprised of both specific valuation allowances and general valuation allowances. A loan is classified as impaired when, based on current information and events, it is probable that the Corporation will be unable to collect both the principal and interest due under the contractual terms of the loan agreement. Specific valuation allowances are established based on management’s analyses of individually impaired loans. Factors considered by management in determining impairment include payment status, evaluations of the underlying collateral, expected cash flows, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is determined to be impaired and is placed on nonaccrual status, all future payments received are applied to principal and 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. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. Loans not impaired but classified as substandard and special mention use a historical loss factor on a rolling five year history of net losses. For all other unclassified loans, the historical loss experience is determined by portfolio class and is based on the actual loss history experienced by the Corporation over the most recent two years . This actual loss experience is supplemented with other qualitative factors based on the risks present for each portfolio class. These qualitative factors include consideration of the following: (1) lending policies and procedures, including underwriting standards and collection, charge-off and recovery policies, (2) national and local economic and business conditions and developments, including the condition of various market segments, (3) loan profiles and volume of the portfolio, (4)the experience, ability, and depth of lending management and staff, (5) the volume and severity of past due, classified and watch-list loans, non-accrual loans, troubled debt restructurings, and other modifications (6) the quality of the Bank’s loan review system and the degree of oversight by the Bank’s Board of Directors, (7) collateral related issues: secured vs. unsecured, type, declining valuation environment and trend of other related factors, (8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations, (9) the effect of external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank’s current portfolio and (10) the impact of the global economy. The allowance for loan losses is increased through a provision for loan losses charged to operations. Loans are charged against the allowance for loan losses when management believes that the collectability of all or a portion of the principal is unlikely. Management's evaluation of the adequacy of the allowance for loan losses is performed on a periodic basis and takes into consideration such factors as the credit risk grade assigned to the loan, historical loan loss experience and review of specific impaired loans. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions.
LOANS HELD FOR SALE	LOANS HELD FOR SALE Certain mortgage loans are originated with the intent to sell. The Corporation typically retains the right to service the mortgages upon sale. Loans held for sale are recorded at the lower of cost or fair value in the aggregate and are regularly evaluated for changes in fair value. Commitments to sell the loans that are originated for sale are recorded at fair value. If necessary, a valuation allowance is established with a charge to income for unrealized losses attributable to a change in market rates.
CAPITAL LEASES	CAPITAL LEASES Capital leases are recorded at the lesser of the present value of future cash outlays using a discounted cash flow, or fair value at the beginning of the lease term. Initially, the capital lease is recorded as a building asset, which is depreciated over the shorter of the term of the lease or the estimated life of the asset, and a corresponding long term lease obligation, which amortizes as payments are made toward the lease. Interest expense is also incurred using the discount rate determined at the beginning of the lease term.
PREMISES AND EQUIPMENT	PREMISES AND EQUIPMENT Land is carried at cost, while buildings, equipment, leasehold improvements and furniture are stated at cost less accumulated depreciation and amortization. Depreciation is charged to current operations under the straight-line method over the estimated useful lives of the assets, which range from 15 to 50 years for buildings and from 3 to 10 years for equipment and furniture. Amortization of leasehold improvements and leased equipment is recognized on the straight-line method over the shorter of the lease term or the estimated life of the asset. Leases of branch offices, which have been capitalized, are included within buildings and depreciated on the straight-line method over the shorter of the lease term or the estimated life of the asset.
BANK OWNED LIFE INSURANCE	BANK OWNED LIFE INSURANCE BOLI is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the cash surrender value are recorded in other income.
OTHER REAL ESTATE	OTHER REAL ESTATE Real estate acquired through foreclosure or deed in lieu of foreclosure is recorded at estimated fair value of the property less estimated costs to dispose at the time of acquisition to establish a new carrying value. Write downs from the carrying value of the loan to estimated fair value which are required at the time of foreclosure are charged to the allowance for loan losses. Subsequent adjustments to the carrying values of such properties resulting from declines in fair value are charged to operations in the period in which the declines occur.
INCOME TAXES	INCOME TAXES The Corporation files a consolidated tax return. Deferred tax assets and liabilities are recognized for future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for unused tax loss carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates to apply to taxable income in the years in which temporary differences are expected to be recovered or settled, or the tax loss carry forwards are expected to be utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. 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.
WEALTH MANAGEMENT GROUP FEE INCOME	WEALTH MANAGEMENT GROUP FEE INCOME Assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheets, since such assets are not assets of the Corporation. Wealth Management Group income is recognized on the accrual method as earned based on contractual rates applied to the balances of individual trust accounts.
POSTRETIREMENT BENEFITS	POSTRETIREMENT BENEFITS Pension Plan: The Chemung Canal Trust Company Pension Plan is a non-contributory defined benefit pension plan. The Pension Plan is a “qualified plan” under the IRS Code and therefore must be funded. Contributions are deposited to the Plan and held in trust. The Plan assets may only be used to pay retirement benefits and eligible plan expenses. The plan was amended such that new employees hired on or after July 1, 2010 would not be eligible to participate in the plan, however, existing participants at that time would continue to accrue benefits. Under the Plan, pension benefits are based upon final average annual compensation where the annual compensation is total base earnings paid plus 401(k) salary deferrals. Bonuses, overtime, commissions and dividends are excluded. The normal retirement benefit equals 1.2% of final average compensation (highest consecutive five years of annual compensation in the prior ten years ) times years of service (up to a maximum of 25 years ), plus 1% of average monthly compensation for each additional year of service (up to a maximum of 10 years ), plus 0.65% of average monthly compensation in excess of covered compensation for each year of credited service up to 35 years . Covered compensation is the average of the social security taxable wage bases in effect for the 35 year period prior to normal social security retirement age. Compensation for purposes of determining benefits under the Plan is reviewed annually. On October 20, 2016, the Corporation amended its noncontributory defined benefit pension plan (“pension plan”) to freeze future retirement benefits after December 31, 2016. Beginning on January 1, 2017, both the pay-based and service-based component of the formula used to determine retirement benefits in the pension plan were frozen so that participants will no longer earn further retirement benefits. The effects of this freeze are reflected in the pension plan disclosures as of December 31, 2016. See Note 12. Defined Contribution Profit Sharing, Savings and Investment Plan: The Corporation also sponsors a 401(K) defined contribution profit sharing, savings and investment plan which covers all eligible employees with a minimum of 1000 hours of annual service. The Corporation makes non-discretionary contributions and discretionary matching and profit sharing contributions to the plan based on the financial results of the Corporation. The plan's assets consist of Chemung Financial Corporation common stock, as well as other common and preferred stocks, U.S. Government securities, corporate bonds and notes, and mutual funds. The plan’s expense is the amount of non-discretionary contributions and discretionary matching and profit sharing contributions, and is charged to other operating expenses in the consolidated statements of income. Due to the freezing of the pension plan, the Corporation amended its defined contribution profit sharing, savings, and investment plan (“401(k)”) for all active participants to supersede the current contribution formula used by the Corporation. Beginning on January 1, 2017 the Corporation will begin contributing a non-discretionary 3% of gross annual wages (as defined by the 401(k) plan) for each participant, regardless of the participant’s deferral, in addition to a 50% match up to 6% of gross annual wages. All new contributions made on or after January 1, 2017 will vest immediately. Defined Benefit Health Care Plan: The Corporation sponsors a defined benefit health care plan that provides postretirement medical benefits to employees who meet minimum age and service requirements. This plan was amended effective July 1, 2006. Prior to this amendment, all retirees age 55 or older were eligible for coverage under the Corporation's self-insured health care plan, contributing 40% of the cost of the coverage. Under the amended plan, coverage for Medicare eligible retirees who reside in the Central New York geographic area is provided under a group sponsored plan with Excellus BlueCross BlueShield called Medicare Blue PPO, with the retiree paying 100% of the premium. Excellus BlueCross BlueShield assumes full liability for the payment of health care benefits incurred after July 1, 2006. Current Medicare eligible retirees who reside outside of the Central New York geographic area were eligible for coverage under the Corporation's self insurance plan thru December 31, 2009, contributing 50% of the cost of coverage. Effective January 1, 2010, these out of area retirees were eligible for coverage under a Medicare Supplement Plan C administered by Excellus BlueCross BlueShield, contributing 50% of the premium. Current retirees between the ages of 55 and 65 , will continue to be eligible for coverage under the Corporation's self insured plan, contributing 50% of the cost of the coverage. Employees who retired after July 1, 2006, and become Medicare eligible will only have access to the Medicare Blue PPO plan. Additionally, effective July 1, 2006, dental benefits were eliminated for all retirees. The cost of the plan is based on actuarial computations of current and future benefits for employees, and is charged to other operating expenses in the consolidated statements of income. On October 20, 2016, the Corporation amended its defined benefit health care plan to not allow any new retirees into the plan, effective January 1, 2017. The effects of this freeze are reflected in the pension plan disclosures as of December 31, 2016. See Note 12. Executive Supplemental Pension Plan: U.S. laws place limitations on compensation amounts that may be included under the Pension Plan. The Executive Supplemental Pension Plan is provided to executives in order to produce total retirement benefits, as a percentage of compensation that is comparable to employees whose compensation is not restricted by the annual compensation limit. Pension amounts, which exceed the applicable Internal Revenue Service code limitations, will be paid under the Executive Supplemental Pension Plan. The Executive Supplemental Pension Plan is a “non-qualified plan” under the Internal Revenue Service Code. Contributions to the Plan are not held in trust; therefore, they may be subject to the claims of creditors in the event of bankruptcy or insolvency. When payments come due under the Plan, cash is distributed from general assets. The cost of the plan is based on actuarial computations of current and future benefits for executives, and is charged to other operating expense in the consolidated statements of income. Defined Contribution Supplemental Executive Retirement Plan: The Defined Contribution Supplemental Executive Retirement Plan is provided to certain executives to motivate and retain key management employees by providing a nonqualified retirement benefit that is payable at retirement, disability, death and certain other events. The Defined Contribution Supplemental Executive Retirement Plan will deliver a retirement benefit comparable to that received by other executive officers participating in the bank’s Defined Benefit Plan. The Supplemental Executive Retirement Plan is intended to be an unfunded plan maintained primarily for the purpose of providing deferred compensation benefits for a select group of management or highly compensated employees under Sections 201(2), 301(a)(3) and 401(a)(1) of the Employee Retirement Income Security Act of 1974. The plan’s expense is the Corporation’s annual contribution plus interest credits.
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Restricted Stock Plan: The Restricted Stock Plan is designed to align the interests of the Corporation’s executives and senior managers with the interests of the Corporation and its shareholders, to ensure the Corporation’s compensation practices are competitive and comparable with those of its peers, and to promote the retention of select management-level employees. Under the terms of the Plan, the Corporation may make discretionary grants of restricted shares of the Corporation’s common stock to or for the benefit of employees selected to participate in the Plan. Each officer of the Corporation, other than the Corporation’s chief executive officer, is eligible to participate in the Plan. Awards are based on the performance, responsibility and contributions of the employee and are targeted at an average of the peer group. The maximum number of shares of the Corporation’s common stock that may be awarded as restricted shares to Plan participants may not exceed 15,000 per calendar year. Twenty percent of the restricted stock awarded to a participant vests each year commencing with the first anniversary date of the award and is 100 percent vested on the fifth anniversary date. Except in the case of the participant’s death, disability, or in the event of a change in control, the participant’s unvested shares of unrestricted stock will be forfeited if the participant leaves the employment of the Corporation or the Bank, with or without cause, or if the participant retires prior to attainment of age 65 . The plan’s expense is recognized as compensation expense ratably over the vesting period for the fair value of the award, measured at the grant date. See Note 13 for more information regarding this Plan. Deferred Directors Fee Plan: A Deferred Directors Fee Plan for non-employee directors provides that directors may elect to defer receipt of all or any part of their fees. Deferrals are either credited with interest compounded quarterly at the Applicable Federal Rate for short-term debt instruments or converted to units, which appreciate or depreciate, as would an actual share of the Corporation’s common stock purchased on the deferral date. Cash deferrals will be paid into an interest bearing account and paid in cash. Units will be paid in shares of common stock. All directors’ fees are charged to other operating expense in the consolidated statements of income. Directors’ Compensation Plan: The purpose of the Directors’ Compensation Plan is to enable the Corporation to attract and retain persons of exceptional ability to serve as directors and stockholders in enhancing the value of the common stock of the Corporation. The Plan was originally established to provide for the cash payment of an annual retainer and fees to non-employee directors serving on the Board of Directors of the Corporation and the Bank. The Plan was subsequently amended to provide: (i) payment of additional compensation to each non-employee director in shares of the Corporation’s common stock in an amount equal to the total cash compensation earned by each non-employee director during the year for service on the Board of Directors of each of the Corporation and the Bank, and for each year of service thereafter, to be distributed from treasury shares in January of the following calendar year; and (ii) payment to the President and CEO of the Corporation and the Bank for his service on the Boards of Directors of the Corporation and the Bank in an amount equal in value to the average cash compensation awarded to non-employee directors who have served twelve (12) months of the previous year. The maximum number of shares of Corporation’s common stock that may be granted under the Plan may not exceed 20,000 per year. The Plan provides that the value of a share of common stock granted under the Plan shall be determined as the average of the closing prices of a share of common stock as quoted on the applicable established securities market for each of the prior 30 trading days ending on December 31 st of the calendar year. The cost of all cash and stock compensation is charged to other operating expenses in the consolidated statements of income. Incentive Compensation Plan: The purpose of the Incentive Compensation Plan is to attract and retain highly qualified officers and key employees, and to motivate such persons to serve the Corporation and the Bank and to expend maximum effort to improve the business results and earnings of the Corporation by providing to such persons an opportunity to acquire or increase a direct proprietary interest in the operations and future success of the Corporation. To this end, the Incentive Compensation Plan provides for the discretionary grant of cash and/or unrestricted stock, i.e., common stock of the Corporation that is free of any restrictions, such as restrictions on transferability, to select officers and key employees as designated by the Board of Directors in its sole discretion. The maximum number of shares that can be awarded as unrestricted stock under the Incentive Compensation Plan to any individual is 10,000 per calendar year; and the maximum amount that may be earned in cash as an Incentive Award in any calendar year by any individual is $300,000 . The right of any eligible employee to receive a grant of an incentive award, whether in the form of cash or unrestricted stock, is subject to performance standards that are specified by either the Compensation Committee or the Board of Directors. The cost of all cash and unrestricted stock compensation is charged to other operating expenses in the consolidated statements of income. Non-qualified Deferred Compensation Plan: The Deferred Compensation Plan allows a select group of management and employees to defer all or a portion of their annual compensation to a future date. Eligible employees are generally highly compensated employees and are designated by the Board of Directors from time to time. Investments in the plan are recorded as trading assets and deferred amounts are an unfunded liability of the Corporation. The plan requires deferral elections be made before the beginning of the calendar year during which the participant will perform the services to which the compensation relates. Participants in the Plan are required to elect a form of distribution, either lump sum payment or annual installments not to exceed ten years , and a time of distribution, either a specified age or a specified date. The terms and conditions for the deferral of compensation are subject to the provisions of 409A of the IRS Code. The income from investments and cost of the plan are recorded as other operating income and other operating expenses, respectively, in the consolidated statements of income.
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND 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 interests 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. The Corporation has selected December 31 as the date to perform the annual impairment test. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. The balances are reviewed for impairment on an ongoing basis or whenever events or changes in business circumstances warrant a review of the carrying value. If impairment is determined to exist, the related write-down of the intangible asset's carrying value is charged to operations. Based on these impairment reviews, the Corporation determined that goodwill and other intangible assets were not impaired at December 31, 2016 . The Corporation's intangible assets with definite useful lives resulted from the purchase of the trust business of Partners Trust Bank in May of 2007, the acquisition of FOFC in April 2011 and the acquisition of six branches of Bank of America in November of 2013, with balances of $1.7 million , $0.5 million and $0.7 million , respectively, at December 31, 2016 . The intangible assets related to the acquisition of Canton Bancorp, Inc. in May 2009 were fully amortized at December 31, 2016. The intangible assets related to the acquisition of three former M&T Bank branch offices in March 2008 were fully amortized at December 31, 2015. The trust business intangible is being amortized to expense over the expected useful life of 15 years . The identifiable core deposit and customer relationship intangibles related to the M&T branch offices, and Canton Bancorp, Inc. acquisitions are being amortized to expense using a 7.25 year accelerated method. The identifiable core deposit related to the branch offices in the Bank of America acquisition is being amortized to expense using a 7 year accelerated method. The identifiable core deposit intangible related to the FOFC acquisition is being amortized using a 10 year accelerated method.
SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE	SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE The Corporation enters into sales of securities under agreements to repurchase. The agreements are treated as financings, and the obligations to repurchase securities sold are reflected as liabilities in the consolidated balance sheets. The amount of the securities underlying the agreements continues to be carried in the Corporation's securities portfolio. The Corporation has agreed to repurchase securities identical to those sold. The securities underlying the agreements are under the Corporation's control.
DERIVATIVES	DERIVATIVES The Corporation utilizes interest rate swaps with commercial borrowers and third-party counterparties as well as agreements with lead banks in participation loan relationships wherein the Corporation guarantees a portion of the fair value of an interest rate swap entered into by the lead bank. These transactions are accounted for as derivatives. The Company’s derivatives are entered into in connection with its asset and liability management activities and not for trading purposes. The Company does not have any derivatives that are designated as hedges and therefore all derivatives are considered free standing and are recorded at fair value as derivative assets or liabilities on the consolidated balance sheets, with changes in fair value recognized in the consolidated statements of income as non-interest income. Premiums received when entering into derivative contracts are recognized as part of the fair value of the derivative asset or liability and are carried at fair value with any gain/loss at inception and any changes in fair value reflected in income. The Corporation does not typically require its commercial customers to post cash or securities as collateral on its program of back-to-back interest rate swap program. The Corporation may need to post collateral, either cash or certain qualified securities, in proportion to potential increases in unrealized loss positions.
OTHER FINANCIAL INSTRUMENTS	OTHER FINANCIAL INSTRUMENTS The Corporation is a party to certain other financial instruments with off-balance sheet risk such as unused portions of lines of credit and commitments to fund new loans. The Corporation's policy is to record such instruments when funded.
ADVERTISING COSTS	ADVERTISING COSTS Costs for advertising products and services or for promoting our corporate image are expensed as incurred.
EARNINGS PER COMMON SHARE	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 as they are earned. All outstanding unvested share based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Restricted stock awards are grants of participating securities. The impact of the participating securities on earnings per share is not material. Earnings per share information is adjusted to present comparative results for stock splits and stock dividends that occur.
COMPREHENSIVE INCOME (LOSS)	COMPREHENSIVE INCOME (LOSS) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale and changes in the funded status of the Corporation’s defined benefit pension plan and other benefit plans, net of the related tax effect, which are also recognized as separate components of equity.
SEGMENT REPORTING	SEGMENT REPORTING The Corporation has identified separate operating segments and internal financial information is primarily reported and aggregated in two lines of business, banking and wealth management services.
RECLASSIFICATION	RECLASSIFICATION Amounts in the prior years' consolidated financial statements are reclassified whenever necessary to conform to the current year's presentation.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS In May 2014, the FASB issued ASU 2014-09, an amendment to Revenue from Contracts with Customers (Topic 606) . The objective of this amendment is to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and IFRS. This update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are in the scope of other standards. In August 2015, the FASB issued ASU 2015-14 to defer for one year the effective date of the new revenue standard. The requires are effective for annual periods and interim periods within fiscal years beginning after December 15, 2017. During 2016, the FASB issued further implementation guidance regarding revenue recognition. This additional guidance included clarification on certain principal versus agent considerations within the implementation of the guidance as well as clarification related to identifying performance obligations and licensing, assessing collectibility, presenting sales taxes, measuring noncash consideration, and certain transition matters. The Corporation intends to adopt the new revenue guidance as of January 1, 2018 and does not expect a significant change upon adoption of the standard, as the new standard will not materially change the way the Corporation currently records revenue for its WMG and fee income from mortgage servicing fees, financial guarantees, and deposit related fees. In January 2016, the FASB issued ASU 2016-01, an amendment to Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10) . The objectives of the ASU are to (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. The amendments in this ASU are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Corporation will adopt all provisions of this ASU as of January 1, 2018 and believes the ASU will not have a material impact on its consolidated financial statements, as the Corporation's equity investment portfolio is less than $1.0 million as of December 31, 2016. In February 2016, the FASB issued ASU No. 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 evaluation 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 $5.0 million for the Corporation's 13 leased facilities and a related capital obligation of the same amount as of January 1, 2019. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . The objectives of the ASU are to simplify accounting for a stock payment's tax consequences and amend how excess tax benefits and a business's payments to cover the tax bills for the shares' recipients should be classified. The amendments allow companies to estimate the number of stock awards they expect to vest, and they revise the withholding requirements for classifying stock awards as equity. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2016, though early adoption is permitted. The Corporation will adopt the new stock compensation guidance as of January 1, 2017 and believes that the ASU will not have a material impact on its consolidated financial statements as employee's are responsible for tax consequences associated with the vesting of their shares. 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 evaluating the potential impact on the Corporation's consolidated financial statements and believes that the ASU may materially change the current process of evaluating the allowance for loan losses. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The objective of the ASU is to reduce the existing diversity in practice relating to eight specific cash flow issues: (1) debt prepayment or debt extinguishment costs, (2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (6) distributions received from equity method investees, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and application of the predominance principal. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, though early adoption is permitted. The adoption of the ASU is not expected to have a significant impact on the Corporation's consolidated financial statements.
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: Investment 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). Trading Assets: Securities that are held to fund a deferred compensation plan are recorded at fair value with changes in fair value included in earnings. The fair values of trading assets 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 credit risk participations are based on credit default rate assumptions (Level 3 inputs).
