BASIS OF PRESENTATION	NOTE A: BASIS OF PRESENTATION The interim financial data as of and for the three and six months ended June 30, 2016 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 4, 2016, the Company, through its subsidiary, CBNA Insurance Agency, Inc. ("CBNA Insurance"), completed its acquisition of WJL Agencies Inc. doing business as The Clark Insurance Agencies ("WJL"), an insurance agency operating in northern New York. The Company paid $0.6 million in cash for the intangible assets of the company. Goodwill in the amount of $0.3 million and intangible assets in the amount of $0.3 million were recorded in conjunction with the acquisition. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date. On December 4, 2015, the Company completed its acquisition of Oneida Financial Corp. ("Oneida"), parent company of Oneida Savings Bank, headquartered in Oneida, New York for approximately $158 million in Company stock and cash, comprised of $56.3 million of cash and the issuance of 2.38 million shares of common stock. Upon the completion of the merger, Community Bank, N.A. ("CBNA" or the "Bank") added 12 branch locations in Oneida and Madison counties and approximately $769 million of assets, including approximately $399 million of loans and $226 million of investment securities, along with $699 million of deposits. Through the acquisition of Oneida, the Company acquired, among others, OneGroup NY, Inc. ("OneGroup") and Oneida Wealth Management, Inc. ("OWM") as wholly-owned subsidiaries primarily engaged in offering insurance and investment advisory services. These subsidiaries complement the Company's other non-banking financial services businesses. 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 date of the acquisition, and were subject to adjustment based on updated information not available at the time of acquisition. During the first quarter of 2016, the carrying amount of other assets decreased by $0.9 million and other liabilities increased by $0.7 million as a result of adjustments made to fair value estimates recorded for the Oneida acquisition. Other assets decreased as a result of new information obtained related to the fair value calculation of loans partially offset by a decrease in the fair value adjustment made to accounts receivable for uncollectible accounts as actual cash receipts exceed anticipated cash receipts. Other liabilities increased as a result of updated information related to deferred taxes. Goodwill increased $1.6 million as a result of these changes in fair value estimates. The above referenced acquisitions expanded the Company's geographical presence in New York and management expects that the Company will benefit from greater geographic diversity and the advantages of other synergistic business development opportunities. The following table summarizes the estimated fair value of the assets acquired and liabilities assumed after considering the measurement period adjustments described above: (000s omitted) 2016 2015 Consideration paid : Cash $ 575 $ 56,266 Community Bank System, Inc. common stock 0 102,202 Total net consideration paid 575 158,468 Recognized amounts of identifiable assets acquired and liabilities assumed: Cash and cash equivalents 0 81,772 Investment securities 0 225,729 Loans 0 399,422 Premises and equipment 0 22,212 Accrued interest receivable 0 1,133 Other assets 0 26,529 Core deposit intangibles 0 2,570 Other intangibles 288 9,994 Deposits 0 (699,241 ) Other liabilities 0 (1,333 ) Total identifiable assets, net 288 68,787 Goodwill $ 287 $ 89,681 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 were aggregated by comparable characteristics and recorded at fair value without a carryover of the related allowance for loan losses. Cash flows for each loan were determined using an estimate of credit losses and an estimated rate of prepayments. Projected monthly cash flows were then discounted to present value using a market-based discount rate. The excess of the undiscounted expected cash flows over the estimated fair value is referred to as the "accretable yield" and is recognized into interest income over the remaining lives of the acquired loans. The following is a summary of the loans acquired from Oneida at the date of acquisition: Acquired Acquired Total Impaired Non-impaired Acquired (000s omitted) Loans Loans Loans Contractually required principal and interest at acquisition $ 5,138 $ 484,937 $ 490,075 Contractual cash flows not expected to be collected (1,977 ) (4,833 ) (6,810 ) Expected cash flows at acquisition 3,161 480,104 483,265 Interest component of expected cash flows (341 ) (83,502 ) (83,843 ) Fair value of acquired loans $ 2,820 $ 396,602 $ 399,422 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 at the present value of the certificates' expected contractual payments discounted at market rates for similar certificates. The core deposit intangibles and other intangibles related to the Oneida acquisition and the other intangibles related to WJL are 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 Banking and All Other segments for the Oneida acquisition and the All Other segment for WJL. Goodwill arising from the Oneida acquisition is not deductible for tax purposes. Goodwill arising from the WJL acquisition is deductible for tax purposes. Direct costs related to the acquisitions were expensed as incurred. Merger and acquisition integration-related expenses amount to $0.3 million and $0.4 million during the three months ended June 30, 2016 and 2015 and $0.3 million and $0.8 million for the six months ended June 30, 2016 and 2015, respectively, and have been separately stated in the Consolidated Statements of Income. Supplemental Pro Forma Financial Information The following unaudited condensed pro forma information assumes the Oneida acquisition had been completed as of January 1, 2015 for the three months and six months ended June 30, 2015. The pro forma information does not include amounts related to WJL as the amounts were immaterial and financial information is not readily available. The table below has been prepared for comparative purposes only and is not necessarily indicative of the actual results that would have been attained had the acquisition occurred as of the beginning of the years presented, nor is it indicative of the Company's future results. Furthermore, the unaudited pro forma information does not reflect management's estimate of any revenue-enhancing opportunities nor anticipated cost savings or the impact of conforming certain acquiree accounting policies to the Company's policies that may have occurred as a result of the integration and consolidation of the acquisitions. The pro forma information set forth below reflects the historical results of Oneida combined with the Company's consolidated statement of income with adjustments related to (a) certain purchase accounting fair value adjustments; (b) amortization of customer lists and core deposit intangibles and (c) changes to effective tax rate as a result of the Company's assets size being above $8 billion on a consolidated basis. Acquisition-related expenses totaling $0.4 million and $0.8 million are excluded from the pro forma information for the three and six months ended June 30, 2015, respectively.

ACCOUNTING POLICIES

ACCOUNTING POLICIES	6 Months Ended
	Jun. 30, 2016
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, 2015 filed with the Securities and Exchange Commission ("SEC") on February 29, 2016. 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 Accounting Standards Codification ("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 loans 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 are 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 loss 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 of 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 can classify its investments in debt and equity securities as held-to-maturity, available-for-sale, or trading. 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. 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, 2016. 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, 2016 represents OTTI. The amortized cost and estimated fair value of debt securities at June 30, 2016, 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: June 30, December 31, (000's omitted) 2016 2015 Consumer mortgage $ 1,779,295 $ 1,769,754 Business lending 1,536,546 1,497,271 Consumer indirect 993,132 935,760 Consumer direct 195,959 195,076 Home equity 399,870 403,514 Gross loans, including deferred origination costs 4,904,802 4,801,375 Allowance for loan losses (46,526 ) (45,401 ) Loans, net of allowance for loan losses $ 4,858,276 $ 4,755,974 The outstanding balance related to credit impaired acquired loans was $8.1 million and $8.5 million at June 30, 2016 and December 31, 2015, 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", "classified", or "doubtful". 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, 2016 December 31, 2015 (000's omitted) Legacy Acquired Total Legacy Acquired Total Pass $ 1,082,841 $ 186,526 $ 1,269,367 $ 1,048,364 $ 219,374 $ 1,267,738 Special mention 135,172 31,724 166,896 124,768 20,007 144,775 Classified 72,283 20,712 92,995 60,181 16,963 77,144 Doubtful 280 0 280 315 0 315 Acquired impaired 0 7,008 7,008 0 7,299 7,299 Total $ 1,290,576 $ 245,970 $ 1,536,546 $ 1,233,628 $ 263,643 $ 1,497,271 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 loans classified as current as well as those classified as 30 - 89 days past due. Nonperforming loans include 90+ days past due and still accruing and nonaccrual loans.

A summary of individually evaluated impaired loans as of June 30, 2016 and December 31, 2015 follows: June 30, December 31, (000's omitted) 2016 2015 Loans with allowance allocation $ 1,187 $ 0 Loans without allowance allocation 601 2,376 Unpaid principal balance 1,788 2,376 Contractual balance 3,401 3,419 Allowance for loan loss allocated 255 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. 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 the three and six months ended June 30, 2016 and 2015 was immaterial. TDRs that are less than $0.5 million are collectively included in the general loan loss allocation and the qualitative review. TDRs that are commercial loans and greater than $0.5 million are individually evaluated for impairment, and if necessary, a specific allocation of the allowance for loan losses is provided. As a result, the determination of the amount of allowance for loan losses related to TDRs is the same as detailed in the critical accounting policies. Information regarding TDRs as of June 30, 2016 and December 31, 2015 is as follows: June 30, 2016 December 31, 2015 (000's omitted) Nonaccrual Accruing Total Nonaccrual Accruing Total # Amount # Amount # Amount # Amount # Amount # Amount Consumer mortgage 43 $ 1,979 44 $ 2,227 87 $ 4,206 37 $ 1,472 54 $ 2,486 91 $ 3,958 Business lending 10 234 5 708 15 942 8 217 6 737 14 954 Consumer indirect 0 0 83 806 83 806 0 0 77 691 77 691 Consumer direct 0 0 10 71 10 71 0 0 32 37 32 37 Home equity 14 240 12 261 26 501 10 203 14 301 24 504 Total 67 $ 2,453 154 $ 4,073 221 $ 6,526 55 $ 1,892 183 $ 4,252 238 $ 6,144 The following table presents information related to loans modified in a TDR during the three months and six months ended June 30, 2016 and 2015.

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: Issuance Par Maturity Trust Date Amount Interest Rate Date Call Price III 7/31/2001 $24.5 million 3 month LIBOR plus 3.58% (4.22%) 7/31/2031 Par IV 12/8/2006 $75 million 3 month LIBOR plus 1.65% (2.30%) 12/15/2036 Par

EARNINGS PER SHARE [Abstract]
EARNINGS PER SHARE	NOTE I: EARNINGS PER SHARE The two class method is used in the calculations of basic and diluted earnings per share. Under the two class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared and participation rights in undistributed earnings. The Company has determined that all of its outstanding non-vested stock awards are participating securities as of June 30, 2016. 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 0.8 million weighted-average anti-dilutive stock options outstanding for the three months ended June 30, 2016, and approximately 0.7 million weighted-average anti-dilutive stock options outstanding for the six months ended June 30, 2016, compared to 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 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 , 2016 Three Months Ended Six Months Ended June 30, June 30, (000's omitted, except per share data) 2016 2015 2016 2015 Net income $ 25,857 $ 23,840 $ 50,260 $ 46,137 Income attributable to unvested stock-based compensation awards (151 ) (99 ) (242 ) (177 ) Income available to common shareholders $ 25,706 $ 23,741 $ 50,018 $ 45,960 Weighted-average common shares outstanding – basic 44,021 40,690 43,942 40,674 Basic earnings per share $ 0.58 $ 0.58 $ 1.14 $ 1.13 Net income $ 25,857 $ 23,840 $ 50,260 $ 46,137 Income attributable to unvested stock-based compensation awards (151 ) (99 ) (242 ) (177 ) Income available to common shareholders $ 25,706 $ 23,741 $ 50,018 $ 45,960 Weighted-average common shares outstanding – basic 44,021 40,690 43,942 40,674 Assumed exercise of stock options 357 404 347 405 Weighted-average common shares outstanding – diluted 44,378 41,094 44,289 41,079 Diluted earnings per share $ 0.58 $ 0.58 $ 1.13 $ 1.12 Stock Repurchase Program At its December 2015 meeting, the Company's Board of Directors (the "Board") approved a new repurchase program authorizing the repurchase of up to 2.2 million shares of the Company's common stock, in accordance with securities laws and regulations, through December 31, 2016. 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. The Company did not repurchase any shares under the authorized plan during the first six months of 2016.

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 amounts of commitments and contingencies are as follows: (000's omitted) June 30, 2016 December 31, 2015 Commitments to extend credit $ 725,561 $ 811,442 Standby letters of credit 19,713 19,053 Total $ 745,274 $ 830,495 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, 2016, 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.

FAIR VALUE

FAIR VALUE [Abstract]
FAIR VALUE	NOTE K: FAIR VALUE 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: ● Quoted prices in active markets for identical assets or liabilities. ● 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. ● 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, 2016 (000's omitted) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale investment securities: U.S. Treasury and agency securities $ 1,992,657 $ 0 $ 0 $ 1,992,657 Obligations of state and political subdivisions 0 645,488 0 645,488 Government agency mortgage-backed securities 0 223,139 0 223,139 Corporate debt securities 0 16,660 0 16,660 Government agency collateralized mortgage obligations 0 11,502 0 11,502 Marketable equity securities 417 0 0 417 Total available-for-sale investment securities 1,993,074 896,789 0 2,889,863 Mortgage loans held for sale 0 514 0 514 Commitments to originate real estate loans for sale 0 0 361 361 Forward sales commitments 0 (78 ) 0 (78 ) Total $ 1,993,074 $ 897,225 $ 361 $ 2,890,660 December 31, 2015 (000's omitted) Level 1 Level 2 Level 3 Total Fair Value Available-for-sale investment securities: U.S. Treasury and agency securities $ 1,899,978 $ 0 $ 0 $ 1,899,978 Obligations of state and political subdivisions 0 666,883 0 666,883 Government agency mortgage-backed securities 0 210,865 0 210,865 Corporate debt securities 0 16,680 0 16,680 Government agency collateralized mortgage obligations 0 13,308 0 13,308 Marketable equity securities 399 0 0 399 Total available-for-sale investment securities 1,900,377 907,736 0 2,808,113 Mortgage loans held for sale 0 932 0 932 Commitments to originate real estate loans for sale 0 0 117 117 Forward sales commitments 0 (37 ) 0 (37 ) Total $ 1,900,377 $ 908,631 $ 117 $ 2,809,125 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 –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. The fair value of mortgage loans held for sale is determined using quoted secondary-market prices of loans with similar characteristics and, as such, has been classified as a Level 2 valuation. The unpaid principal value of mortgage loans held for sale at June 30, 2016 was approximately $0.5 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 June 30, June 30, 2016 2015 2016 2015 (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 $ 282 $ 152 $ 117 $ 185 Total losses included in earnings (1) (282 ) (152 ) (399 ) (337 ) Commitments to originate real estate loans held for sale, net 361 195 643 347 Ending balance $ 361 $ 195 $ 361 $ 195 (1) Amounts included in earnings associated with the commitments to originate real estate loans for sale are reported as a component of other banking services in the Consolidated Statement of Income The fair value information of assets and liabilities measured on a non-recurring basis presented below is not as of the period-end, but rather as of the date the fair value adjustment was recorded closest to the date presented. June 30, 2016 December 31, 2015 (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 $ 932 $ 932 $ 0 $ 0 $ 1,765 $ 1,765 Mortgage servicing rights 0 0 638 638 0 0 0 0 Other real estate owned 0 0 1,726 1,726 0 0 2,088 2,088 Total $ 0 $ 0 $ 3,296 $ 3,296 $ 0 $ 0 $ 3,853 $ 3,853 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 6% to 94% at June 30, 2016 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, 2016 of approximately $0.1 million. 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. 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, 2016 Valuation Technique Significant Unobservable Inputs Significant Unobservable Input Range (Weighted Average) Other real estate owned $ 1,726 Fair Value of Collateral Estimated cost of disposal/market adjustment 6 . %) Impaired loans 932 Fair Value of Collateral Estimated cost of disposal/market adjustment 9.0% - 16.9% (12.8 %) Commitments to originate real estate loans for sale 361 Discounted cash flow Embedded servicing value 1 % Mortgage servicing rights 638 Discounted cash flow Weighted average constant prepayment rate 11.8 % Weighted average discount rate 2.24 % Adequate compensation $7/loan (000's omitted) Fair Value at December 31, 2015 Valuation Technique Significant Unobservable Inputs Significant Unobservable Input Range (Weighted Average) Other real estate owned $ 2,088 Fair value of collateral Estimated cost of disposal/market adjustment 5.3% - 74.0% (27.7 %) Impaired loans 1,765 Fair value of collateral Estimated cost of disposal/market adjustment 9.0% - 20.0% (17.9 %) Commitments to originate real estate loans for sale 117 Discounted cash flow Embedded servicing value 1 % 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, 2016 and December 31, 2015 are as follows: June 30, 2016 December 31, 2015 Carrying Fair Carrying Fair (000's omitted) Value Value Value Value Financial assets: Net loans $ 4,858,276 $ 4,928,960 $ 4,755,974 $ 4,808,856 Financial liabilities: Deposits 6,957,854 6,956,075 6,873,474 6,871,098 Borrowings 267,600 267,600 301,300 301,300 Subordinated debt held by unconsolidated subsidiary trusts 102,158 80,108 102,146 84,680 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, which were immaterial at June 30, 2016. The effect of the changes to these derivatives for the three and six months then ended was also immaterial.

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 Accounting Standards Codification ("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 loans 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 are 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 loss 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 of 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 can classify its investments in debt and equity securities as held-to-maturity, available-for-sale, or trading. 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. 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, 2016. 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.

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.
