BASIS OF PRESENTATION [Abstract]
BASIS OF PRESENTATION	NOTE A: BASIS OF PRESENTATION The interim financial data as of and for the three and six months ended June 30, 2015 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 [Abstract]
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. 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 2014: (000’s omitted) Consideration paid: Cash/Total net consideration paid $ 924 Recognized amounts of identifiable assets acquired and liabilities assumed: Other assets 163 Other intangibles 578 Total identifiable assets 741 Goodwill $ 183 The other intangible related to the EBS-RMSCO acquisition is being amortized using an accelerated method over their estimated useful life of eight years. The goodwill, which is not amortized for book purposes, was assigned to the Employee Benefit Services segment for the EBS-RMSCO acquisition and is deductible for tax purposes. Direct costs related to the acquisitions were expensed as incurred. Merger and acquisition integration-related expenses amount to $0.4 million and $0.8 million, respectively, in the three and six months ended June 30, 2015 and $0.1 million in the six months ended June 30, 2014, and have been separately stated in the Consolidated Statements of Income. Supplemental pro forma financial information related to the EBS-RMSCO acquisition has not been provided as it would be impracticable to do so. Historical financial information regarding EBS-RMSCO is not accessible and, thus, the amounts would require estimates so significant as to render the disclosure irrelevant. On February 24, 2015, the Company announced that it had entered into a definitive agreement to acquire Oneida Financial Corp. (“Oneida”), parent company of Oneida Savings Bank, headquartered in Oneida, NY, for approximately $142 million in Company stock and cash. The acquisition will extend the Company’s Central New York banking service area and complement and expand the Company’s existing service capacity in insurance, benefits administration and wealth management. Upon the completion of the merger, the Bank will add 12 branch locations and approximately $850 million of assets, including approximately $390 million of loans and $740 million of deposits. The Oneida shareholders have approved the acquisition, which is expected to close during the fourth quarter of 2015, pending customary regulatory approvals. The Company expects to incur certain one-time, transaction-related costs during the remainder of 2015.

ACCOUNTING POLICIES

ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 2015
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 55 through 60 of the Annual Report on Form 10-K for the year ended December 31, 2014 filed with the Securities and Exchange Commission (“SEC”) on March 2, 2015. 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 direct; consumer 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 The Company has classified its investments in debt and equity securities as either 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 consequently has not used the held-to-maturity classification since. 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 June 30, 2015. 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 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.

The majority of the obligations of state and political subdivisions and corporations carry a credit rating of A or better. Additionally, a majority of the obligations of state and political subdivisions carry a secondary level of credit enhancement. The Company does not intend to sell these securities, nor is it more likely than not that the Company will be required to sell these securities prior to recovery of the amortized cost. The unrealized losses in the portfolios are primarily attributable to changes in interest rates. As such, management does not believe any individual unrealized loss as of June 30, 2015 represents OTTI. The amortized cost and estimated fair value of debt securities at June 30, 2015, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

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: (000's omitted) June 30, December 31, Consumer mortgage $ 1,608,064 $ 1,613,384 Business lending 1,295,889 1,262,484 Consumer indirect 837,449 833,968 Consumer direct 181,623 184,028 Home equity 340,578 342,342 Gross loans, including deferred origination costs 4,263,603 4,236,206 Allowance for loan losses (45,282 ) (45,341 ) Loans, net of allowance for loan losses $ 4,218,321 $ 4,190,865 The outstanding balance related to credit impaired acquired loans was $5.7 million and $6.1 million at June 30, 2015 and December 31, 2014, respectively.

As a result interest income, through the accretion of the difference between the carrying amount of the loans and the expected cashflows, is being recognized on all acquired impaired loans. 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: June 30, 2015 December 31, 2014 (000’s omitted) Legacy Acquired Total Legacy Acquired Total Pass $ 998,964 $ 88,229 $ 1,087,193 $ 949,960 $ 93,510 $ 1,043,470 Special mention 104,313 14,140 118,453 103,176 18,038 121,214 Classified 64,280 20,825 85,105 71,458 21,030 92,488 Doubtful 0 0 0 0 0 0 Acquired impaired 0 5,138 5,138 0 5,312 5,312 Total $ 1,167,557 $ 128,332 $ 1,295,889 $ 1,124,594 $ 137,890 $ 1,262,484 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 June 30, 2015: Legacy Loans (000’s omitted) Consumer Consumer Consumer Home Total Performing $ 1,530,102 $ 836,706 $ 177,234 $ 283,151 $ 2,827,193 Nonperforming 14,344 26 9 2,264 16,643 Total $ 1,544,446 $ 836,732 $ 177,243 $ 285,415 $ 2,843,836 Acquired Loans (000’s omitted) Consumer Consumer Consumer Home Total Performing $ 61,799 $ 717 $ 4,362 $ 54,741 $ 121,619 Nonperforming 1,819 0 18 422 2,259 Total $ 63,618 $ 717 $ 4,380 $ 55,163 $ 123,878 The following table details the balances in all other loan categories at December 31, 2014: Legacy Loans (000’s omitted) Consumer Consumer Consumer Home Total Performing $ 1,529,035 $ 832,653 $ 178,547 $ 280,706 $ 2,820,941 Nonperforming 15,366 92 38 2,367 17,863 Total $ 1,544,401 $ 832,745 $ 178,585 $ 283,073 $ 2,838,804 Acquired Loans (000’s omitted) Consumer Consumer Consumer Home Total Performing $ 66,629 $ 1,223 $ 5,425 $ 58,797 $ 132,074 Nonperforming 2,354 0 18 472 2,844 Total $ 68,983 $ 1,223 $ 5,443 $ 59,269 $ 134,918 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 June 30, 2015 and December 31, 2014 follows: (000’s omitted) June 30, December 31, Loans with allowance allocation $ 569 $ 0 Loans without allowance allocation 614 0 Carrying balance 1,183 0 Contractual balance 1,193 0 Specifically allocated allowance 63 0 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”), 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 2015 and 2014 was immaterial. TDRs that are 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 June 30, 2015 and December 31, 2014 is as follows: June 30, 2015 December 31, 2014 (000’s omitted) Nonaccrual Accruing Total Nonaccrual Accruing Total # Amount # Amount # Amount # Amount # Amount # Amount Consumer mortgage 44 $ 1,691 35 $ 1,544 79 $ 3,235 49 $ 2,092 37 $ 1,770 86 $ 3,862 Business lending 3 228 4 572 7 800 6 442 3 468 9 910 Consumer indirect 0 0 72 653 72 653 0 0 79 615 79 615 Consumer direct 0 0 19 47 19 47 0 0 25 69 25 69 Home equity 8 108 12 264 20 372 13 218 13 278 26 496 Total 55 $ 2,027 142 $ 3,080 197 $ 5,107 68 $ 2,752 157 $ 3,200 225 $ 5,952 The following tables present information related to loans modified in a TDR during the three and six months ended June 30, 2015 and 2014.

MANDATORILY REDEEMABLE PREFERRED SECURITIES [Abstract]
MANDATORILY REDEEMABLE PREFERRED SECURITIES	NOTE G: MANDATORILY REDEEMABLE PREFERRED SECURITIES The Company sponsors two business trusts, Community Statutory Trust III and Community Capital Trust IV, of which 100% of the common stock is owned by the Company. The trusts were formed for the purpose of issuing company-obligated mandatorily redeemable preferred securities to third-party investors and investing the proceeds from the sale of such preferred securities solely in junior subordinated debt securities of the Company. The debentures held by each trust are the sole assets of that trust. Distributions on the preferred securities issued by each trust are payable quarterly at a rate per annum equal to the interest rate being earned by the trust on the debentures held by that trust and are recorded as interest expense in the consolidated financial statements. The preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the debentures. The Company has entered into agreements which, taken collectively, fully and unconditionally guarantee the preferred securities subject to the terms of each of the guarantees. The terms of the preferred securities of each trust are as follows: Trust Issuance Par Interest Rate Maturity Call Price III 7/31/2001 $24.5 million 3 month LIBOR plus 3.58% (3.86%) 7/31/2031 Par IV 12/8/2006 $75 million 3 month LIBOR plus 1.65% (1.94%) 12/15/2036 Par

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 0.6 million weighted-average anti-dilutive stock options outstanding for the three months ended June 30, 2015, and approximately 0.4 million weighted-average anti-dilutive stock options outstanding for the six months ended June 30, 2015, compared to approximately 0.3 million weighted-average anti-dilutive stock options outstanding for the three months ended June 30, 2014, and approximately 0.2 million weighted-average anti-dilutive stock options outstanding for the six months ended June 30, 2014 that were not included in the computation below. The following is a reconciliation of basic to diluted earnings per share for the three and six months ended June 30, 2015 Three Months Ended Six Months Ended (000's omitted, except per share data) 2015 2014 2015 2014 Net income $ 23,840 $ 23,676 $ 46,137 $ 45,850 Income attributable to unvested stock-based compensation awards (99 ) (123 ) (177 ) (221 ) Income available to common shareholders $ 23,741 $ 23,553 $ 45,960 $ 45,629 Weighted-average common shares outstanding – basic 40,690 40,574 40,674 40,517 Basic earnings per share $ 0.58 $ 0.58 $ 1.13 $ 1.13 Net income $ 23,840 $ 23,676 $ 46,137 $ 45,850 Income attributable to unvested stock-based compensation awards (99 ) (123 ) (177 ) (221 ) Income available to common shareholders $ 23,741 $ 23,553 $ 45,960 $ 45,629 Weighted-average common shares outstanding – basic 40,690 40,574 40,674 40,517 Assumed exercise of stock options 404 484 405 497 Weighted-average common shares outstanding – diluted 41,094 41,058 41,079 41,014 Diluted earnings per share $ 0.58 $ 0.57 $ 1.12 $ 1.11 Stock Repurchase Program At its December 2014 meeting, the Company’s Board of Directors (the “Board”) approved a new repurchase program authorizing the repurchase of up to 2,000,000 shares of the Company’s common stock, in accordance with securities laws and regulations, through December 31, 2015. Any repurchased shares will be used for general corporate purposes, including those related to stock plan activities. The timing and extent of repurchases will depend on market conditions and other corporate considerations as determined at the Company’s discretion. During the first six months of 2015, the Company repurchased 265,230 shares of its common stock in open market transactions, compared to 123,000 shares repurchased during 2014.

COMMITMENTS, CONTINGENT LIABILITIES AND RESTRICTIONS [Abstract]
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) June 30, 2015 December 31, 2014 Commitments to extend credit $ 729,174 $ 733,827 Standby letters of credit 18,062 23,916 Total $ 747,236 $ 757,743 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 June 30, 2015, 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. On July 14, 2015, the Court issued an order preliminarily approving the settlement reached in the first of two related class actions pending in the United States District Court for the Middle District of Pennsylvania, which cases were commenced on October 30, 2013 and May 23, 2014, respectively. The two related cases allege, on behalf of similarly situated class members, that notices provided by the Bank in connection with the repossession of automobiles failed to comply with certain requirements of the Pennsylvania and New York Uniform Commercial Code and related statutes. In accordance with mediation occurring in September 2014, the settlement provides for establishment of a settlement fund of $2.8 million in exchange for release of all claims of the class members covered by these actions. A litigation settlement charge of $2.8 million with respect to the settlement of the class actions was previously recorded in the third quarter of 2014. The settlement is subject to the Court’s final approval following notice to the class members, including the ability of class members to oppose or opt-out of the settlement.

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. June 30, 2015 (000's omitted) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale investment securities: U.S. Treasury and agency securities $ 1,893,445 $ 0 $ 0 $ 1,893,445 Obligations of state and political subdivisions 0 662,764 0 662,764 Government agency mortgage-backed securities 0 218,755 0 218,755 Corporate debt securities 0 26,817 0 26,817 Government agency collateralized mortgage obligations 0 15,655 0 15,655 Marketable equity securities 425 0 0 425 Total available-for-sale investment securities 1,893,870 923,991 0 2,817,861 Mortgage loans held for sale 0 1,031 0 1,031 Commitments to originate real estate loans for sale 0 0 195 195 Forward sales commitments 0 (81 ) 0 (81 ) Total $ 1,893,870 $ 924,941 $ 195 $ 2,819,006 December 31, 2014 (000's omitted) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale investment securities: U.S. Treasury and agency securities $ 1,496,667 $ 21,066 $ 0 $ 1,517,733 Obligations of state and political subdivisions 0 671,903 0 671,903 Government agency mortgage-backed securities 0 237,728 0 237,728 Corporate debt securities 0 27,091 0 27,091 Government agency collateralized mortgage obligations 0 18,025 0 18,025 Marketable equity securities 445 0 0 445 Total available-for-sale investment securities 1,497,112 975,813 0 2,472,925 Mortgage loans held for sale 0 1,042 0 1,042 Commitments to originate real estate loans for sale 0 0 185 185 Forward sales commitments 0 (43 ) 0 (43 ) Total $ 1,497,112 $ 976,812 $ 185 $ 2,474,109 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 values of available-for-sale investment securities are 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 June 30, 2015 is approximately $1.0 million. The unrealized gain on mortgage loans held for sale was recognized in mortgage banking and other income in the consolidated statement and is immaterial. · 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: Three Months Ended Six Months Ended 2015 2014 2015 2014 (000's omitted) Commitments to Originate Real Estate Loans for Sale Commitments to Originate Real Estate Loans for Sale Commitments to Originate Real Estate Loans for Sale Commitments to Originate Real Estate Loans for Sale Beginning balance $ 152 $ 67 $ 185 $ 44 Total losses included in earnings (1) (152 ) (67 ) (337 ) (111 ) Commitments to originate real estate loans held for sale, net 195 142 347 209 Ending balance $ 195 $ 142 $ 195 $ 142 (1) June 30, 2015 December 31, 2014 (000's omitted) Level 1 Level 2 Level 3 Total Fair Value Level 1 Level 2 Level 3 Total Fair Value Impaired loans $ 0 $ 0 $ 506 $ 506 $ 0 $ 0 $ 0 $ 0 Other real estate owned 0 0 2,324 2,324 0 0 1,855 1,855 Mortgage servicing rights 0 0 485 485 0 0 0 0 Total $ 0 $ 0 $ 3,315 $ 3,315 $ 0 $ 0 $ 1,855 $ 1,855 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. 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 7% to 49% at June 30, 2015 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 a valuation allowance at June 30, 2015 of approximately $0.1 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 2014 or thus far in 2015. The significant unobservable inputs used in the determination of fair value of assets classified as Level 3 on a recurring or non-recurring basis are as follows: (000's omitted) Fair Value at June 30, 2015 Valuation Technique Significant Unobservable Inputs Significant Unobservable Input Range (Weighted Average) Impaired loans $ 506 Fair Value of Collateral Estimated cost of disposal/market adjustment 10.0% - 32.0% (28.4 %) Other real estate owned 2,324 Fair Value of Collateral Estimated cost of disposal/market adjustment 7.1% - %) Commitments to originate real estate loans for sale 195 Discounted cash flow Embedded servicing value 1 % Mortgage servicing rights 485 Discounted cash flow Weighted average constant prepayment rate 14.6 % Weighted average discount rate 3.58 % Adequate compensation $7/loan The significant unobservable inputs used in the determination of fair value of assets classified as Level 3 on a recurring or non-recurring basis as of December 31, 2014 are as follows: (000's omitted) Fair Value at December 31, 2014 Valuation Technique Significant Unobservable Inputs Significant nobservable Input Range (Weighted Average) Other real estate owned $ 1,855 Fair value of collateral Estimated cost of disposal/market adjustment 10.0% - 77.5% (30.6 %) Commitments to originate real estate loans for sale 185 Discounted cash flow Embedded servicing value 1 % 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 June 30, 2015 and December 31, 2014 are as follows: June 30, 2015 December 31, 2014 (000's omitted) Carrying Fair Carrying Fair Financial assets: Net loans $ 4,218,321 $ 4,295,518 $ 4,190,865 $ 4,251,565 Financial liabilities: Deposits 6,086,820 6,085,968 5,935,264 5,935,690 Borrowings 566,200 566,200 338,000 338,000 Subordinated debt held by unconsolidated subsidiary trusts 102,134 92,484 102,122 85,189 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 [Abstract]
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. The following table presents the Company’s derivative financial instruments, their estimated fair values, and balance sheet location as of June 30, 2015: (000's omitted) Location Notional Fair Value Derivatives not designated as hedging instruments: Forward sales commitments Other liabilities $ 7,816 $ (81 ) Commitments to originate real estate loans for sale Other assets 9,803 195 Total derivatives, net $ 114 The following table presents the Company’s derivative financial instruments and the location of the net gain or loss recognized in the statement of income for the three and six months ended June 30, 2015: Loss Recognized in the Statement of Income (000's omitted) Location Three Months Ending June 30, 2015 Six Months Ending June 30, 2015 Forward sales commitments Mortgage banking and other services $ (59 ) $ (38 ) Commitments to originate real estate loans for sale Mortgage banking and other services 43 10 Total, net $ (16 ) $ (28 )

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 direct; consumer 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 either 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 consequently has not used the held-to-maturity classification since. 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 June 30, 2015. 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 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.
