	The interim financial data as of and for the three and nine months ended September 30, 2014 is unaudited; however, in the opinion of Community Bank System, Inc. (the “Company”), the interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods in conformity with generally accepted accounting principles (“GAAP”).  The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

ACQUISITIONS	'
	NOTE B:  ACQUISITIONS
	On January 1, 2014, the Company, through its subsidiary, Harbridge Consulting Group, LLC (“Harbridge”), completed its acquisition of a professional services practice from EBS-RMSCO, Inc., a subsidiary of The Lifetime Healthcare Companies (“EBS-RMSCO”).  This professional services practice, which provides actuarial valuation and consulting services to clients who sponsor pension and post-retirement medical and welfare plans, enhances the Company’s participation in the Western New York market.  The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date.
	On December 13, 2013, Community Bank, N.A. (the “Bank” or “CBNA”) completed its acquisition of eight branches in Northern Pennsylvania from Bank of America, N.A. (“B of A”), acquiring approximately $303 million of deposits and $1 million of loans.  The assumed deposits consist primarily of core deposits (checking, savings and money market accounts) and the purchased loans consist of in-market performing commercial loans. Under the terms of the purchase agreement, the Bank paid a blended deposit premium of 2.4%, or approximately $7.3 million.  The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date.
	The assets and liabilities assumed in the acquisitions were recorded at their estimated fair values based on management's best estimates using information available at the dates of the acquisition, and are subject to adjustment based on updated information not available at the time of acquisition.  The following table summarizes the estimated fair value of the assets acquired and liabilities assumed during 2013 and the first nine months of 2014:
	(000’s omitted)	2014	2013
	Consideration paid/(received):
	Cash/Total net consideration paid/(received)	$924	($291,980)
	Recognized amounts of identifiable assets acquired and
	liabilities assumed:
	Loans	0	1,106
	Premises and equipment	0	2,549
	Accrued interest receivable	0	5
	Other assets and liabilities, net	163	(18)
	Other intangibles	578	9
	Core deposit intangibles	0	2,537
	Deposits	0	(303,456)
	Total identifiable assets/(liabilities), net	741	(297,268)
	Goodwill	$183	$5,288
	The fair value of checking, savings and money market deposit accounts acquired were assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand.  Certificate of deposit accounts were valued as the present value of the certificates’ expected contractual payments discounted at market rates for similar certificates, which approximated their book values.
	The core deposit intangible and other intangibles related to the B of A and EBS-RMSCO acquisitions are being amortized using an accelerated method over their estimated useful lives of eight years.  The goodwill, which is not amortized for book purposes, was assigned to the Banking segment for the B of A acquisition and the Employee Benefit Services segment for the EBS-RMSCO acquisition.  The goodwill arising from the B of A branch and the EBS-RMSCO acquisitions is deductible for tax purposes.
	Direct costs related to the acquisitions were expensed as incurred.  Merger and acquisition integration-related expenses amount to $0.1 million in the nine months ended September 30, 2014 and have been separately stated in the Consolidated Statements of Income.  There were no merger and acquisition integration-related expenses for the three months ended September 30, 2014.
	Supplemental pro forma financial information related to the B of A and EBS-RMSCO acquisitions has not been provided as it would be impracticable to do so.  Historical financial information regarding the acquired branches is not accessible and, thus, the amounts would require estimates so significant as to render the disclosure irrelevant.

ACCOUNTING POLICIES [Abstract]	'
ACCOUNTING POLICIES	'
	NOTE C:  ACCOUNTING POLICIES
	The accounting policies of the Company, as applied in the consolidated interim financial statements presented herein, are substantially the same as those followed on an annual basis as presented on pages 56 through 61 of the Annual Report on Form 10-K for the year ended December 31, 2013 filed with the Securities and Exchange Commission (“SEC”) on March 3, 2014.
	Critical Accounting Policies
	Acquired loans
	Acquired loans are initially recorded at their acquisition date fair values.  The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
	Acquired impaired loans
	Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30.  The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans using the interest method. The difference between contractually required payments at acquisition and the undiscounted cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses and other contractually required payments that the Company does not expect to collect. Subsequent decreases in expected cash flows are recognized as impairments through a charge to the provision for credit losses resulting in an increase in the allowance for loan losses. Subsequent improvements in expected cash flows result in a recovery of previously recorded allowance for loan losses or a reversal of a corresponding amount of the non-accretable discount, which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
	Acquired loans that met the criteria for non-accrual of interest prior to acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or non-performing and may accrue interest on these loans, including the impact of any accretable discount.
	Acquired non-impaired loans
	Acquired loans that do not meet the requirements under ASC 310-30 are considered acquired non-impaired loans. The difference between the acquisition date fair value and the outstanding balance represents the fair value adjustment for a loan and includes both credit and interest rate considerations. Fair value adjustments may be discounts (or premiums) to a loan’s cost basis and are accreted (or amortized) to net interest income (or expense) over the loan’s remaining life in accordance with ASC 310- 20. Fair value adjustments for revolving loans are accreted (or amortized) using a straight line method. Term loans are accreted (or amortized) using the constant effective yield method.
	Subsequent to the purchase date, the methods used to estimate the allowance for loan losses for the acquired non-impaired loans is consistent with the policy described below.  However, the Company compares the net realizable value of the loans to the carrying value, for loans collectively evaluated for impairment.  The carrying value represents the net of the loan’s unpaid principal balance and the remaining purchase discount (or premium) that has yet to be accreted into interest income.  When the carrying value exceeds the net realizable value, an allowance for loan losses is recognized.
	Allowance for Loan Losses
	Management continually evaluates the credit quality of the Company’s loan portfolio, and performs a formal review of the adequacy of the allowance for loan losses on a quarterly basis.  The allowance reflects management’s best estimate of probable losses inherent in the loan portfolio.  Determination of the allowance is subjective in nature and requires significant estimates.   The Company’s allowance methodology consists of two broad components - general and specific loan loss allocations.
	The general loan loss allocation is composed of two calculations that are computed on five main loan segments:  business lending, consumer installment - direct, consumer installment - indirect, home equity and consumer mortgage.  The first calculation is quantitative and determines an allowance level based on the latest 36 months of historical net charge-off data for each loan class (commercial loans exclude balances with specific loan loss allocations).  The second calculation is qualitative and takes into consideration eight qualitative environmental factors:  levels and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations.    A component of the qualitative calculation is the unallocated allowance for loan loss.  The qualitative and quantitative calculations are added together to determine the general loan loss allocation.  The specific loan loss allocation relates to individual commercial loans that are both greater than $0.5 million and in a nonaccruing status with respect to interest.  Specific loan losses are based on discounted estimated cash flows, including any cash flows resulting from the conversion of collateral or collateral shortfalls.  The allowance levels computed from the specific and general loan loss allocation methods are combined with unallocated allowances and allowances needed for acquired loans to derive the total required allowance for loan losses to be reflected on the Consolidated Statement of Condition.
	Loan losses are charged off against the allowance, while recoveries of amounts previously charged off are credited to the allowance.  A provision for loan losses is charged to operations based on management’s periodic evaluation of factors previously mentioned.

	The Company has classified its investments in debt and equity securities as held-to-maturity or available-for-sale.  Held-to-maturity securities are those for which the Company has the positive intent and ability to hold until maturity, and are reported at cost, which is adjusted for amortization of premiums and accretion of discounts.  During December 2013, the Company reclassified its held-to-maturity portfolio to available-for-sale and the Company will not be able to use the held-to-maturity classification for the foreseeable future.  Securities classified as available-for-sale are reported at fair value with net unrealized gains and losses reflected as a separate component of shareholders' equity, net of applicable income taxes.  None of the Company's investment securities have been classified as trading securities at September 30, 2014.  Certain equity securities are stated at cost and include restricted stock of the Federal Reserve Bank of New York (“Federal Reserve”) and Federal Home Loan Bank of New York (“FHLB”).
	Fair values for investment securities are based upon quoted market prices, where available.  If quoted market prices are not available, fair values are based upon quoted market prices of comparable instruments, or a discounted cash flow model using market estimates of interest rates and volatility.
	The Company conducts an assessment of all securities in an unrealized loss position to determine if other-than-temporary impairment (“OTTI”) exists on a quarterly basis. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis.  The OTTI assessment considers the security structure, recent security collateral performance metrics, if applicable, external credit ratings, failure of the issuer to make scheduled interest or principal payments, judgment about and expectations of future performance, and relevant independent industry research, analysis and forecasts. The severity of the impairment and the length of time the security has been impaired is also considered in the assessment.  The assessment of whether an OTTI decline exists is performed on each security, regardless of the classification of the security as available-for-sale or held-to-maturity and involves a high degree of subjectivity and judgment that is based on the information available to management at a point in time.
	An OTTI loss must be recognized for a debt security in an unrealized loss position if there is intent to sell the security or it is more likely than not the Company will be required to sell the security prior to recovery of its amortized cost basis. In this situation, the amount of loss recognized in income is equal to the difference between the fair value and the amortized cost basis of the security. Even if management does not have the intent, and it is not more likely than not that the Company will be required to sell the securities, an evaluation of the expected cash flows to be received is performed to determine if a credit loss has occurred. For debt securities, a critical component of the evaluation for OTTI is the identification of credit-impaired securities, where the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the security.  In the event of a credit loss, only the amount of impairment associated with the credit loss would be recognized in income. The portion of the unrealized loss relating to other factors, such as liquidity conditions in the market or changes in market interest rates, is recorded in accumulated other comprehensive loss.
	Equity securities are also evaluated to determine whether the unrealized loss is expected to be recoverable based on whether evidence exists to support a realizable value equal to or greater than the amortized cost basis. If it is probable that the amortized cost basis will not be recovered, taking into consideration the estimated recovery period and the ability to hold the equity security until recovery, OTTI is recognized in earnings equal to the difference between the fair value and the amortized cost basis of the security.
	The specific identification method is used in determining the realized gains and losses on sales of investment securities and OTTI charges.  Premiums and discounts on securities are amortized and accreted, respectively, on the interest method basis over the period to maturity or estimated life of the related security.  Purchases and sales of securities are recognized on a trade date basis.
	Intangible Assets
	Intangible assets include core deposit intangibles, customer relationship intangibles and goodwill arising from acquisitions. Core deposit intangibles and customer relationship intangibles are amortized on either an accelerated or straight-line basis over periods ranging from seven to 20 years. The initial and ongoing carrying value of goodwill and other intangible assets is based upon discounted cash flow modeling techniques that require management to make estimates regarding the amount and timing of expected future cash flows.  It also requires use of a discount rate that reflects the current return requirements of the market in relation to present risk-free interest rates, required equity market premiums, peer volatility indicators, and company-specific risk indicators.
	The Company evaluates goodwill for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment.  The implied fair value of a reporting unit’s goodwill is compared to its carrying amount and the impairment loss is measured by the excess of the carrying value over fair value.  The fair value of each reporting unit is compared to the carrying amount of that reporting unit in order to determine if impairment is indicated.
	Retirement Benefits
	The Company provides defined benefit pension benefits to eligible employees and post-retirement health and life insurance benefits to certain eligible retirees.  The Company also provides deferred compensation and supplemental executive retirement plans for selected current and former employees, officers, and directors.  Expense under these plans is charged to current operations and consists of several components of net periodic benefit cost based on various actuarial assumptions regarding future experience under the plans, including discount rate, rate of future compensation increases and expected return on plan assets.
	New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40):  Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.  This new guidance clarifies when an “in substance” repossession or foreclosure occurs, and requires all creditors who obtain physical possession (resulting from an in substance repossession or foreclosure) of residential real estate property collateralizing a consumer mortgage loan in satisfaction of a receivable to reclassify the collateralized mortgage loan such that the loan should be derecognized and the collateral asset recognized. This guidance is effective prospectively for the Company for annual and interim periods beginning after December 15, 2014.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This new guidance supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects consideration to which the entity expects to be entitled in exchange for those goods and services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.  This guidance is effective prospectively for the Company for annual and interim periods beginning after December 15, 2016.  The Company is currently evaluating the effect the guidance will have on the Company’s consolidated financial statements.

LOANS [Abstract]	'
LOANS	'
	NOTE E:  LOANS
	The segments of the Company’s loan portfolio are disaggregated into the following classes that allow management to monitor risk and performance:
	·	Consumer mortgages consist primarily of fixed rate residential instruments, typically 10 – 30 years in contractual term, secured by first liens on real property.
	·	Business lending is comprised of general purpose commercial and industrial loans including, but not limited to agricultural-related and dealer floor plans, as well as mortgages on commercial properties.
	·	Consumer indirect consists primarily of installment loans originated through selected dealerships and are secured by automobiles, marine and other recreational vehicles.
	·	Consumer direct consists of all other loans to consumers such as personal installment loans and lines of credit.
	·	Home equity products are consumer purpose installment loans or lines of credit most often secured by a first or second lien position on residential real estate with terms up to 30 years.
	The balances of these classes are summarized as follows:
		September 30,	December 31,
	(000's omitted)	2014	2013

The Company uses several credit quality indicators to assess credit risk in an ongoing manner.  The Company’s primary credit quality indicator for its business lending portfolio is an internal credit risk rating system that categorizes loans as “pass”, “special mention”, or “classified”.  Credit risk ratings are applied individually to those classes of loans that have significant or unique credit characteristics that benefit from a case-by-case evaluation.  In general, the following are the definitions of the Company’s credit quality indicators:
Pass	The condition of the borrower and the performance of the loans are satisfactory or better.
Special Mention	The condition of the borrower has deteriorated although the loan performs as agreed.
Classified	The condition of the borrower has significantly deteriorated and the performance of the loan could further deteriorate, if deficiencies are not corrected.
Doubtful	The condition of the borrower has deteriorated to the point that collection of the balance is improbable based on current facts and conditions.
The following table shows the amount of business lending loans by credit quality category:
	30-Sep-14				31-Dec-13
(000’s omitted)	Legacy	Acquired	Total		Legacy	Acquired	Total

All other loans are underwritten and structured using standardized criteria and characteristics, primarily payment performance, and are normally risk rated and monitored collectively on a monthly basis.  These are typically loans to individuals in the consumer categories and are delineated as either performing or nonperforming.   Performing loans include current, 30 - 89 days past due and acquired impaired loans.  Nonperforming loans include 90+ days past due and still accruing and nonaccrual loans. The following table details the balances in all other loan categories at September 30, 2014:

All loan classes are collectively evaluated for impairment except business lending, as described in Note C.  A summary of individually evaluated impaired loans as of September 30, 2014 and December 31, 2013 follows:
	September 30,	December 31,
(000’s omitted)	2014	2013
Loans with allowance allocation	$945	$945
Loans without allowance allocation	0	600
Carrying balance	945	1,545
Contractual balance	1,003	1,852
Specifically allocated allowance	50	50
In the course of working with borrowers, the Company may choose to restructure the contractual terms of certain loans.  In this scenario, the Company attempts to work-out an alternative payment schedule with the borrower in order to optimize collectability of the loan.  Any loans that are modified are reviewed by the Company to identify if a troubled debt restructuring (“TDR”) has occurred, which is when, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession to the borrower that it would not otherwise consider.  Terms may be modified to fit the ability of the borrower to repay in line with its current financial standing and the restructuring of the loan may include the transfer of assets from the borrower to satisfy the debt, a modification of loan terms, or a combination of the two.  With regard to determination of the amount of the allowance for loan losses, troubled debt restructured loans are considered to be impaired.  As a result, the determination of the amount of allowance for loan losses related to impaired loans for each portfolio segment within TDRs is the same as detailed previously.
In accordance with the clarified guidance issued by the Office of the Comptroller of the Currency (“OCC”) in 2012 addressing the accounting for certain loans that have been discharged in Chapter 7 bankruptcy, loans that have been discharged in Chapter 7 bankruptcy but not reaffirmed by the borrower, are classified as TDRs, irrespective of payment history or delinquency status, even if the repayment terms for the loan have not been otherwise modified.  The Company’s lien position against the underlying collateral remains unchanged.  Pursuant to that guidance, the Company records a charge-off equal to any portion of the carrying value that exceeds the net realizable value of the collateral.  The amount of loss incurred in 2014 and 2013 was immaterial.
TDRs less than $0.5 million are collectively included in the general loan loss allocation and the qualitative review, if necessary.  Commercial loans greater than $0.5 million are individually evaluated for impairment, and if necessary, a specific allocation of the allowance for loan losses is provided.
Information regarding TDRs as of September 30, 2014 and December 31, 2013 is as follows:

EARNINGS PER SHARE [Abstract]	'
EARNINGS PER SHARE	'
	NOTE I:  EARNINGS PER SHARE
	Basic earnings per share are computed based on the weighted-average of the common shares outstanding for the period.  Diluted earnings per share are based on the weighted-average of the shares outstanding adjusted for the dilutive effect of restricted stock and the assumed exercise of stock options during the year.  The dilutive effect of options is calculated using the treasury stock method of accounting.  The treasury stock method determines the number of common shares that would be outstanding if all the dilutive options (those where the average market price is greater than the exercise price) were exercised and the proceeds were used to repurchase common shares in the open market at the average market price for the applicable time period.  There were approximately 0.3 million weighted-average anti-dilutive stock options outstanding for the three months ended September 30, 2014, and approximately 0.2 million weighted-average anti-dilutive stock options outstanding for the nine months ended September 30, 2014, compared to approximately 0.3 million weighted-average anti-dilutive stock options outstanding for the three months ended September 30, 2013, and approximately 0.5 million weighted-average anti-dilutive stock options outstanding for the nine months ended September 30, 2013 that were not included in the computation below.

COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS	'
	NOTE J:  COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS
	The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments consist primarily of commitments to extend credit and standby letters of credit.  Commitments to extend credit are agreements to lend to customers, generally having fixed expiration dates or other termination clauses that may require payment of a fee.  These commitments consist principally of unused commercial and consumer credit lines.  Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of an underlying contract with a third party.  The credit risks associated with commitments to extend credit and standby letters of credit are essentially the same as that involved with extending loans to customers and are subject to the Company’s normal credit policies.  Collateral may be obtained based on management’s assessment of the customer’s creditworthiness.  The fair value of the standby letters of credit is immaterial for disclosure.
	The contract amount of commitments and contingencies are as follows:
	(000's omitted)	September 30,	December 31,
		2014	2013
	Commitments to extend credit	$674,401	$704,904
	Standby letters of credit	23,892	24,449
	Total	$698,293	$729,353
	The Company and its subsidiaries are subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. As of September 30, 2014, management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company or its subsidiaries will be material to the Company’s consolidated financial position. On at least a quarterly basis the Company assesses its liabilities and contingencies in connection with such legal proceedings. For those matters where it is probable that the Company will incur losses and the amounts of the losses can be reasonably estimated, the Company records an expense and corresponding liability in its consolidated financial statements. To the extent the pending or threatened litigation could result in exposure in excess of that liability, the amount of such excess is not currently estimable. The range of reasonably possible losses for matters where an exposure is not currently estimable or considered probable, beyond the existing recorded liabilities, is between $0 and $1 million in the aggregate. Although the Company does not believe that the outcome of pending litigation will be material to the Company’s consolidated financial position, it cannot rule out the possibility that such outcomes will be material to the consolidated results of operations for a particular reporting period in the future.
	The Bank reached a settlement in two class actions pending in the United States District Court for the Middle District of Pennsylvania which were commenced October 30, 2013 and May 29, 2014, respectively.  The first action alleged that notices provided by the Bank in connection with the repossession of the named plaintiff’s automobile failed to comply with certain requirements of the Pennsylvania and New York Uniform Commercial Code (UCC) and related statutes.  The plaintiff sought to pursue the action as a class action on behalf of herself and similarly situated plaintiffs who had their automobiles repossessed and sought to recover statutory damages under the UCC. The second action filed May 29, 2014 contained similar allegations, which the plaintiff also sought to pursue as a class action for statutory damages. In both cases, the Bank contested the allegations that the notices were deficient, asserted various legal defenses and counterclaims, and opposed class certification in both of the cases.  On September 30, 2014, the Bank reached an agreement in principle to settle both actions for $2.8 million in exchange for releases of all claims.  The settlement is subject to final documentation, notice to the class members and Court approval. A litigation settlement charge of $2.8 million with respect to the settlement of the class actions was recorded in the third quarter.

FAIR VALUE [Abstract]	'
FAIR VALUE	'
	NOTE K:  FAIR VALUE
	Accounting standards allow entities an irrevocable option to measure certain financial assets and financial liabilities at fair value.  Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings.  The Company has elected to value loans held for sale at fair value in order to more closely match the gains and losses associated with loans held for sale with the gains and losses on forward sales contracts.  Accordingly, the impact on the valuation will be recognized in the Company’s consolidated statement of income.  All mortgage loans held for sale are current and in performing status.
	Accounting standards establish a framework for measuring fair value and require certain disclosures about such fair value instruments.  It defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e. exit price).  Inputs used to measure fair value are classified into the following hierarchy:
	·	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	·	Level 2 – Quoted prices in active markets for similar assets or liabilities, or quoted prices for identical or similar assets or
		liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.
	·	Level 3 – Significant valuation assumptions not readily observable in a market.
	A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.  The following tables set forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis.  There were no transfers between any of the levels for the periods presented.

	The valuation techniques used to measure fair value for the items in the table above are as follows:
	·	Available for sale investment securities – The fair value of available-for-sale investment securities is based upon quoted prices, if available.  If quoted prices are not available, fair values are measured using quoted market prices for similar securities or model-based valuation techniques.  Level 1 securities include U.S. Treasury obligations and marketable equity securities that are traded by dealers or brokers in active over-the-counter markets.  Level 2 securities include U.S. agency securities, mortgage-backed securities issued by government-sponsored entities, municipal securities and corporate debt securities that are valued by reference to prices for similar securities or through model-based techniques in which all significant inputs, such as reported trades, trade execution data, LIBOR swap yield curve, market prepayment speeds, credit information, market spreads, and security’s terms and conditions, are observable.  See Note D for further disclosure of the fair value of investment securities.
	·	Mortgage loans held for sale – Mortgage loans held for sale are carried at fair value, which is determined using quoted secondary-market prices of loans with similar characteristics and, as such, have been classified as a Level 2 valuation.  The unpaid principal value of mortgage loans held for sale at September 30, 2014 is approximately $0.7 million.  The unrealized gain on mortgage loans held for sale of approximately $0.02 million was recognized in mortgage banking and other income in the consolidated statement.
	·	Forward sales commitments – The Company enters into forward sales commitments to sell certain residential real estate loans.  Such commitments are considered to be derivative financial instruments and, therefore, are carried at estimated fair value in the other asset or other liability section of the consolidated balance sheet.  The fair value of these forward sales commitments is primarily measured by obtaining pricing from certain government-sponsored entities and reflects the underlying price the entity would pay the Company for an immediate sale on these mortgages.  As such, these instruments are classified as Level 2 in the fair value hierarchy.
	·	Commitments to originate real estate loans for sale – The Company enters into various commitments to originate residential real estate loans for sale.  Such commitments are considered to be derivative financial instruments and, therefore, are carried at estimated fair value in the other asset or other liability section of the consolidated balance sheet.  The estimated fair value of these commitments is determined using quoted secondary market prices obtained from certain government-sponsored entities.  Additionally, accounting guidance requires the expected net future cash flows related to the associated servicing of the loan to be included in the fair value measurement of the derivative.  The expected net future cash flows are based on a valuation model that calculates the present value of estimated net servicing income.  The valuation model incorporates assumptions that market participants would use in estimating future net servicing income.  Such assumptions include estimates of the cost of servicing loans, appropriate discount rate and prepayment speeds.  The determination of expected net cash flows is considered a significant unobservable input contributing to the Level 3 classification of commitments to originate real estate loans for sale.
	The changes in Level 3 assets measured at fair value on a recurring basis are summarized in the following tables:

Loans are generally not recorded at fair value on a recurring basis.  Periodically, the Company records nonrecurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans.  Nonrecurring adjustments also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace, adjusted for non-observable inputs.  Thus, the resulting nonrecurring fair value measurements are generally classified as Level 3. Estimates of fair value used for other collateral supporting commercial loans generally are based on assumptions not observable in the marketplace and, therefore, such valuations classify as Level 3.  At December 31, 2013, impaired loans recorded at fair value consisted of one loan that was valued using a purchase offer that did not require an adjustment for estimated costs.  As such, no unobservable inputs were utilized and it was classified as a Level 2 valuation.
Other real estate owned (“OREO”) is valued at the time the loan is foreclosed upon and the asset is transferred to OREO. The value is based primarily on third party appraisals, less costs to sell. The appraisals are sometimes further discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the customer and customer’s business. Such discounts are significant, ranging from 10% to 75% at September 30, 2014 and result in a Level 3 classification of the inputs for determining fair value. OREO is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. The Company recovers the carrying value of OREO through the sale of the property. The ability to affect future sales prices is subject to market conditions and factors beyond the Company’s control and may impact the estimated fair value of a property.
Originated mortgage servicing rights are recorded at their fair value at the time of sale of the underlying loan, and are amortized in proportion to and over the estimated period of net servicing income.  The fair value of mortgage servicing rights is based on a valuation model incorporating inputs that market participants would use in estimating future net servicing income.  Such inputs include estimates of the cost of servicing loans, appropriate discount rate and prepayment speeds and are considered to be unobservable and contribute to the Level 3 classification of mortgage servicing rights.  In accordance with GAAP, the Company must record impairment charges, on a nonrecurring basis, when the carrying value of a stratum exceeds its estimated fair value.  Impairment is recognized through a valuation allowance.  There is no valuation allowance at September 30, 2014 as the fair value of mortgage servicing rights of approximately $1.4 million exceeded the carrying value of approximately $1.1 million.
The Company evaluates goodwill for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment.  The fair value of each reporting unit is compared to the carrying amount of that reporting unit in order to determine if impairment is indicated.  If so, the implied fair value of the reporting unit’s goodwill is compared to its carrying amount and the impairment loss is measured by the excess of the carrying value of the goodwill over fair value of the goodwill.  In such situations, the Company performs a discounted cash flow modeling technique that requires management to make estimates regarding the amount and timing of expected future cash flows of the assets and liabilities of the reporting unit that enable the Company to calculate the implied fair value of the goodwill.  It also requires use of a discount rate that reflects the current return expectation of the market in relation to present risk-free interest rates, expected equity market premiums, peer volatility indicators and company-specific risk indicators.  The Company did not recognize an impairment charge during 2013 or thus far in 2014.

The Company determines fair values based on quoted market values, where available, estimates of present values, or other valuation techniques.  Those techniques are significantly affected by the assumptions used, including, but not limited to, the discount rate and estimates of future cash flows.  In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in immediate settlement of the instrument.  Certain financial instruments and all nonfinancial instruments are excluded from fair value disclosure requirements.  Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.
The carrying amounts and estimated fair values of the Company’s other financial instruments that are not accounted for at fair value at September 30, 2014 and December 31, 2013 are as follows:

The following is a further description of the principal valuation methods used by the Company to estimate the fair values of its financial instruments.
Loans have been classified as a Level 3 valuation.  Fair values for variable rate loans that reprice frequently are based on carrying values.  Fair values for fixed rate loans are estimated using discounted cash flows and interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.
Deposits have been classified as a Level 2 valuation.  The fair value of demand deposits, interest-bearing checking deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date.  The fair value of time deposit obligations are based on current market rates for similar products.
Borrowings have been classified as a Level 2 valuation.  The fair value of FHLB overnight advances is the amount payable on demand at the reporting date.  Fair values for long-term borrowings are estimated using discounted cash flows and interest rates currently being offered on similar borrowings, and are immaterial as of the reporting dates.
Subordinated debt held by unconsolidated subsidiary trusts have been classified as a Level 2 valuation.   The fair value of subordinated debt held by unconsolidated subsidiary trusts are estimated using discounted cash flows and interest rates currently being offered on similar securities.
Other financial assets and liabilities – Cash and cash equivalents have been classified as a Level 1 valuation, while accrued interest receivable and accrued interest payable have been classified as a Level 2 valuation.  The fair values of each approximate the respective carrying values because the instruments are payable on demand or have short-term maturities and present relatively low credit risk and interest rate risk.

DERIVATIVE INSTRUMENTS	'
	NOTE L:  DERIVATIVE INSTRUMENTS
	The Company is party to derivative financial instruments in the normal course of its business to meet the financing needs of its customers and to manage its own exposure to fluctuations in interest rates.  These financial instruments have been limited to commitments to originate real estate loans held for sale and forward sales commitments.  The Company does not hold or issue derivative financial instruments for trading or other speculative purposes.
	The Company enters into forward sales commitments for the future delivery of residential mortgage loans, and interest rate lock commitments to fund loans at a specified interest rate.  The forward sales commitments are utilized to reduce interest rate risk associated with interest rate lock commitments and loans held for sale.  Changes in the estimated fair value of the forward sales commitments and interest rate lock commitments subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time.  At inception and during the life of the interest rate lock commitment, the Company includes the expected net future cash flows related to the associated servicing of the loan as part of the fair value measurement of the interest rate lock commitments.  These derivatives are recorded at fair value.

ACCOUNTING POLICIES (Policies)	9 Months Ended

ACCOUNTING POLICIES [Abstract]	'
Acquired loans	'
	Acquired loans
	Acquired loans are initially recorded at their acquisition date fair values.  The carryover of allowance for loan losses is prohibited as any credit losses in the loans are included in the determination of the fair value of the loans at the acquisition date. Fair values for acquired loans are based on a discounted cash flow methodology that involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate.
	Acquired impaired loans
	Acquired loans that have evidence of deterioration in credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments are accounted for as impaired loans under ASC 310-30.  The excess of undiscounted cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized into interest income over the remaining life of the loans using the interest method. The difference between contractually required payments at acquisition and the undiscounted cash flows expected to be collected at acquisition is referred to as the non-accretable discount. The non-accretable discount represents estimated future credit losses and other contractually required payments that the Company does not expect to collect. Subsequent decreases in expected cash flows are recognized as impairments through a charge to the provision for credit losses resulting in an increase in the allowance for loan losses. Subsequent improvements in expected cash flows result in a recovery of previously recorded allowance for loan losses or a reversal of a corresponding amount of the non-accretable discount, which the Company then reclassifies as an accretable discount that is recognized into interest income over the remaining life of the loans using the interest method.
	Acquired loans that met the criteria for non-accrual of interest prior to acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or non-performing and may accrue interest on these loans, including the impact of any accretable discount.
	Acquired non-impaired loans
	Acquired loans that do not meet the requirements under ASC 310-30 are considered acquired non-impaired loans. The difference between the acquisition date fair value and the outstanding balance represents the fair value adjustment for a loan and includes both credit and interest rate considerations. Fair value adjustments may be discounts (or premiums) to a loan’s cost basis and are accreted (or amortized) to net interest income (or expense) over the loan’s remaining life in accordance with ASC 310- 20. Fair value adjustments for revolving loans are accreted (or amortized) using a straight line method. Term loans are accreted (or amortized) using the constant effective yield method.
	Subsequent to the purchase date, the methods used to estimate the allowance for loan losses for the acquired non-impaired loans is consistent with the policy described below.  However, the Company compares the net realizable value of the loans to the carrying value, for loans collectively evaluated for impairment.  The carrying value represents the net of the loan’s unpaid principal balance and the remaining purchase discount (or premium) that has yet to be accreted into interest income.  When the carrying value exceeds the net realizable value, an allowance for loan losses is recognized.
Allowance for Loan Losses	'
	Allowance for Loan Losses
	Management continually evaluates the credit quality of the Company’s loan portfolio, and performs a formal review of the adequacy of the allowance for loan losses on a quarterly basis.  The allowance reflects management’s best estimate of probable losses inherent in the loan portfolio.  Determination of the allowance is subjective in nature and requires significant estimates.   The Company’s allowance methodology consists of two broad components - general and specific loan loss allocations.
	The general loan loss allocation is composed of two calculations that are computed on five main loan segments:  business lending, consumer installment - direct, consumer installment - indirect, home equity and consumer mortgage.  The first calculation is quantitative and determines an allowance level based on the latest 36 months of historical net charge-off data for each loan class (commercial loans exclude balances with specific loan loss allocations).  The second calculation is qualitative and takes into consideration eight qualitative environmental factors:  levels and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards, and other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations.    A component of the qualitative calculation is the unallocated allowance for loan loss.  The qualitative and quantitative calculations are added together to determine the general loan loss allocation.  The specific loan loss allocation relates to individual commercial loans that are both greater than $0.5 million and in a nonaccruing status with respect to interest.  Specific loan losses are based on discounted estimated cash flows, including any cash flows resulting from the conversion of collateral or collateral shortfalls.  The allowance levels computed from the specific and general loan loss allocation methods are combined with unallocated allowances and allowances needed for acquired loans to derive the total required allowance for loan losses to be reflected on the Consolidated Statement of Condition.
	Loan losses are charged off against the allowance, while recoveries of amounts previously charged off are credited to the allowance.  A provision for loan losses is charged to operations based on management’s periodic evaluation of factors previously mentioned.
Investment Securities	'
	Investment Securities
	The Company has classified its investments in debt and equity securities as held-to-maturity or available-for-sale.  Held-to-maturity securities are those for which the Company has the positive intent and ability to hold until maturity, and are reported at cost, which is adjusted for amortization of premiums and accretion of discounts.  During December 2013, the Company reclassified its held-to-maturity portfolio to available-for-sale and the Company will not be able to use the held-to-maturity classification for the foreseeable future.  Securities classified as available-for-sale are reported at fair value with net unrealized gains and losses reflected as a separate component of shareholders' equity, net of applicable income taxes.  None of the Company's investment securities have been classified as trading securities at September 30, 2014.  Certain equity securities are stated at cost and include restricted stock of the Federal Reserve Bank of New York (“Federal Reserve”) and Federal Home Loan Bank of New York (“FHLB”).
	Fair values for investment securities are based upon quoted market prices, where available.  If quoted market prices are not available, fair values are based upon quoted market prices of comparable instruments, or a discounted cash flow model using market estimates of interest rates and volatility.
	The Company conducts an assessment of all securities in an unrealized loss position to determine if other-than-temporary impairment (“OTTI”) exists on a quarterly basis. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis.  The OTTI assessment considers the security structure, recent security collateral performance metrics, if applicable, external credit ratings, failure of the issuer to make scheduled interest or principal payments, judgment about and expectations of future performance, and relevant independent industry research, analysis and forecasts. The severity of the impairment and the length of time the security has been impaired is also considered in the assessment.  The assessment of whether an OTTI decline exists is performed on each security, regardless of the classification of the security as available-for-sale or held-to-maturity and involves a high degree of subjectivity and judgment that is based on the information available to management at a point in time.
	An OTTI loss must be recognized for a debt security in an unrealized loss position if there is intent to sell the security or it is more likely than not the Company will be required to sell the security prior to recovery of its amortized cost basis. In this situation, the amount of loss recognized in income is equal to the difference between the fair value and the amortized cost basis of the security. Even if management does not have the intent, and it is not more likely than not that the Company will be required to sell the securities, an evaluation of the expected cash flows to be received is performed to determine if a credit loss has occurred. For debt securities, a critical component of the evaluation for OTTI is the identification of credit-impaired securities, where the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the security.  In the event of a credit loss, only the amount of impairment associated with the credit loss would be recognized in income. The portion of the unrealized loss relating to other factors, such as liquidity conditions in the market or changes in market interest rates, is recorded in accumulated other comprehensive loss.
	Equity securities are also evaluated to determine whether the unrealized loss is expected to be recoverable based on whether evidence exists to support a realizable value equal to or greater than the amortized cost basis. If it is probable that the amortized cost basis will not be recovered, taking into consideration the estimated recovery period and the ability to hold the equity security until recovery, OTTI is recognized in earnings equal to the difference between the fair value and the amortized cost basis of the security.
	The specific identification method is used in determining the realized gains and losses on sales of investment securities and OTTI charges.  Premiums and discounts on securities are amortized and accreted, respectively, on the interest method basis over the period to maturity or estimated life of the related security.  Purchases and sales of securities are recognized on a trade date basis.
Intangible Assets	'
	Intangible Assets
	Intangible assets include core deposit intangibles, customer relationship intangibles and goodwill arising from acquisitions. Core deposit intangibles and customer relationship intangibles are amortized on either an accelerated or straight-line basis over periods ranging from seven to 20 years. The initial and ongoing carrying value of goodwill and other intangible assets is based upon discounted cash flow modeling techniques that require management to make estimates regarding the amount and timing of expected future cash flows.  It also requires use of a discount rate that reflects the current return requirements of the market in relation to present risk-free interest rates, required equity market premiums, peer volatility indicators, and company-specific risk indicators.
	The Company evaluates goodwill for impairment on an annual basis, or more often if events or circumstances indicate there may be impairment.  The implied fair value of a reporting unit’s goodwill is compared to its carrying amount and the impairment loss is measured by the excess of the carrying value over fair value.  The fair value of each reporting unit is compared to the carrying amount of that reporting unit in order to determine if impairment is indicated.
Retirement Benefits	'
	Retirement Benefits
	The Company provides defined benefit pension benefits to eligible employees and post-retirement health and life insurance benefits to certain eligible retirees.  The Company also provides deferred compensation and supplemental executive retirement plans for selected current and former employees, officers, and directors.  Expense under these plans is charged to current operations and consists of several components of net periodic benefit cost based on various actuarial assumptions regarding future experience under the plans, including discount rate, rate of future compensation increases and expected return on plan assets.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-04, Receivables – Troubled Debt Restructurings by Creditors (Subtopic 310-40):  Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.  This new guidance clarifies when an “in substance” repossession or foreclosure occurs, and requires all creditors who obtain physical possession (resulting from an in substance repossession or foreclosure) of residential real estate property collateralizing a consumer mortgage loan in satisfaction of a receivable to reclassify the collateralized mortgage loan such that the loan should be derecognized and the collateral asset recognized. This guidance is effective prospectively for the Company for annual and interim periods beginning after December 15, 2014.  The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606).  This new guidance supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects consideration to which the entity expects to be entitled in exchange for those goods and services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract.  This guidance is effective prospectively for the Company for annual and interim periods beginning after December 15, 2016.  The Company is currently evaluating the effect the guidance will have on the Company’s consolidated financial statements.
