Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Financial Institutions, Inc., (the "Parent") is a financial holding company organized in 1931 under the laws of New York State ("New York" or "NYS"). The Company offers a broad array of deposit, lending, insurance services and other financial services to individuals, municipalities and businesses in Western and Central New York through its wholly-owned New York chartered banking subsidiary, Five Star Bank (the "Bank"). The Company has also expanded its indirect lending network to include relationships with franchised automobile dealers in the Capital District of New York and Northern Pennsylvania. On August 1, 2014, the Company acquired Scott Danahy Naylon Co., Inc., a full service insurance agency located in Amherst, New York. As a result of the acquisition the Company now provides insurance and risk consulting services through its wholly-owned insurance subsidiary, Scott Danahy Naylon, LLC ("SDN").
	The accounting and reporting policies conform to general practices within the banking industry and to U.S. generally accepted accounting principles ("GAAP").
	The Company has evaluated events and transactions for potential recognition or disclosure through the day the financial statements were issued.
	The following is a description of the Company's significant accounting policies.
	(a.) Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	(b.) Use of Estimates
	In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the statement of financial condition and reported amounts of revenue and expenses during the reporting period. Material estimates relate to the determination of the allowance for loan losses, the carrying value of goodwill and deferred tax assets, the valuation and other than temporary impairment ("OTTI") considerations related to the securities portfolio, and assumptions used in the defined benefit pension plan accounting. These estimates and assumptions are based on management's best estimates and judgment and are evaluated on an ongoing basis using historical experience and other factors, including the current economic environment. The Company adjusts these estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from the Company's estimates.
	(c.) Cash Flow Reporting
	Cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits in other banks. Net cash flows are reported for loans, deposit transactions and short-term borrowings.
	Supplemental cash flow information is summarized as follows for the years ended December 31 (in thousands):
			2014		2013			2012
	Cash payments:
	Interest expense	$	6,826	$	7,750		$	10,438
	Income taxes		13,665		8,095			4,014
	Noncash investing and financing activities:
	Real estate and other assets acquired in settlement of loans	$	394	$	726		$	322
	Accrued and declared unpaid dividends		3,177		2,981			2,562
	Increase (decrease) in net unsettled security purchases		568		(51,112	)		51,135
	Securities transferred from available for sale to held to maturity		12,802		227,330			-
	Loans transferred from held for sale to held for investment		853		3,727			-
	Common stock issued for acquisition		5,400		-			-
	Assets acquired and liabilities assumed in business combinations:
	Loans and other non-cash assets, excluding goodwill and core
	deposit intangible asset		1,007		-			77,912
	Deposits and other liabilities		1,112		-			287,331
	(d.) Investment Securities
	Investment securities are classified as either available for sale or held to maturity. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and are recorded at amortized cost. Other investment securities are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported as a component of comprehensive income and shareholders' equity.
	Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Securities are evaluated periodically to determine whether a decline in their fair value is other than temporary. Management utilizes criteria such as, the current intent to hold or sell the security, the magnitude and duration of the decline and, when appropriate, consideration of negative changes in expected cash flows, creditworthiness, near term prospects of issuers, the level of credit subordination, estimated loss severity, and delinquencies, to determine whether a loss in value is other than temporary. The term "other than temporary" is not intended to indicate that the decline is permanent, but indicates that the prospect for a near-term recovery of value is not necessarily favorable. Declines in the fair value of investment securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit issues or concerns, or the security is intended to be sold. The amount of impairment related to non-credit related factors is recognized in other comprehensive income. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
	(e.) Loans Held for Sale and Loan Servicing Rights
	The Company generally makes the determination of whether to identify a mortgage as held for sale at the time the loan is closed based on the Company's intent and ability to hold the loan. Loans held for sale are recorded at the lower of cost or market computed on the aggregate portfolio basis. The amount, by which cost exceeds market value, if any, is accounted for as a valuation allowance with changes included in the determination of results of operations for the period in which the change occurs. The amount of loan origination cost and fees are deferred at origination of the loans and recognized as part of the gain or loss on sale of the loans, determined using the specific identification method, in the consolidated statements of income.
	The Company originates and sells certain residential real estate loans in the secondary market. The Company typically retains the right to service the mortgages upon sale. Mortgage-servicing rights ("MSRs") represent the cost of acquiring the contractual rights to service loans for others. MSRs are recorded at their fair value at the time a loan is sold and servicing rights are retained. MSRs are reported in other assets in the consolidated statements of financial position and are amortized to noninterest income in the consolidated statements of income in proportion to and over the period of estimated net servicing income. The Company uses a valuation model that calculates the present value of future cash flows to determine the fair value of servicing rights. In using this valuation method, the Company incorporates assumptions to estimate future net servicing income, which include estimates of the cost to service the loan, the discount rate, an inflation rate and prepayment speeds. On a quarterly basis, the Company evaluates its MSRs for impairment and charges any such impairment to current period earnings. In order to evaluate its MSRs the Company stratifies the related mortgage loans on the basis of their predominant risk characteristics, such as interest rates, year of origination and term, using discounted cash flows and market-based assumptions. Impairment of MSRs is recognized through a valuation allowance, determined by estimating the fair value of each stratum and comparing it to its carrying value. Subsequent increases in fair value are adjusted through the valuation allowance, but only to the extent of the valuation allowance.
	Mortgage loan servicing includes collecting monthly mortgagor payments, forwarding payments and related accounting reports to investors, collecting escrow deposits for the payment of mortgagor property taxes and insurance, paying taxes and insurance from escrow funds when due and administrating foreclosure actions when necessary. Loan servicing income (a component of noninterest income in the consolidated statements of income) consists of fees earned for servicing mortgage loans sold to third parties, net of amortization expense and impairment losses associated with capitalized mortgage servicing assets.
	(f.) Loans
	Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Loans are carried at the principal amount outstanding, net of any unearned income and unamortized deferred fees and costs on originated loans. Loan origination fees and certain direct loan origination costs are deferred, and the net amount is amortized into net interest income over the contractual life of the related loans or over the commitment period as an adjustment of yield. Interest income on loans is based on the principal balance outstanding computed using the effective interest method.
	A loan is considered delinquent when a payment has not been received in accordance with the contractual terms. The accrual of interest income for commercial loans is discontinued when there is a clear indication that the borrower's cash flow may not be sufficient to meet payments as they become due, while the accrual of interest income for retail loans is discontinued when loans reach specific delinquency levels. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments, unless the loan is well secured and in the process of collection. Additionally, if management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management's practice to place such loans on a nonaccrual status immediately, rather than delaying such action until the loans become 90 days past due. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed, amortization of related deferred loan fees or costs is suspended, and income is recorded only to the extent that interest payments are subsequently received in cash and a determination has been made that the principal balance of the loan is collectible. If collectability of the principal is in doubt, payments received are applied to loan principal. A nonaccrual loan may be returned to accrual status when all delinquent principal and interest payments become current in accordance with the terms of the loan agreement, the borrower has demonstrated a period of sustained performance (generally a minimum of six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
	The Company's loan policy dictates the guidelines to be followed in determining when a loan is charged-off. All charge offs are approved by the Bank's senior loan officers or loan committees, depending on the amount of the charge off, and are reported in aggregate to the Bank's Board of Directors. Commercial business and commercial mortgage loans are charged-off when a determination is made that the financial condition of the borrower indicates that the loan will not be collectible in the ordinary course of business. Residential mortgage loans and home equities are generally charged-off or written down when the credit becomes severely delinquent and the balance exceeds the fair value of the property less costs to sell. Indirect and other consumer loans, both secured and unsecured, are generally charged-off in full during the month in which the loan becomes 120 days past due, unless the collateral is in the process of repossession in accordance with the Company's policy.
	A loan is accounted for as a troubled debt restructuring if the Company, for economic or legal reasons related to the borrower's financial condition, grants a significant concession to the borrower that it would not otherwise consider. A troubled debt restructuring may involve the receipt of assets from the debtor in partial or full satisfaction of the loan, or a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk, or some combination of these concessions. Troubled debt restructurings generally remain on nonaccrual status until there is a sustained period of payment performance (usually six months or longer) and there is a reasonable assurance that the payments will continue. See Allowance for Loan Losses below for further policy discussion and see Note 5 – Loans for additional information.
	(g.) Off-Balance Sheet Financial Instruments
	In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, standby letters of credit and financial guarantees. Such financial instruments are recorded in the consolidated financial statements when they are funded or when related fees are incurred or received. The Company periodically evaluates the credit risks inherent in these commitments and establishes loss allowances for such risks if and when these are deemed necessary.
	The Company recognizes as liabilities the fair value of the obligations undertaken in issuing the guarantees under the standby letters of credit, net of the related amortization at inception. The fair value approximates the unamortized fees received from the customers for issuing the standby letters of credit. The fees are deferred and recognized on a straight-line basis over the commitment period. Standby letters of credit outstanding at December 31, 2014 had original terms ranging from one to five years.
	Fees received for providing loan commitments and letters of credit that result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to other income as banking fees and commissions over the commitment period when funding is not expected.
	(h.) Allowance for Loan Losses
	The allowance for loan losses is established through charges to earnings in the form of a provision for loan losses. When a loan or portion of a loan is determined to be uncollectible, the portion deemed uncollectible is charged against the allowance and subsequent recoveries, if any, are credited to the allowance.
	The allowance for loan losses is evaluated on a regular basis and is based upon periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	The allowance consists of specific and general components. Specific allowances are established for impaired loans. Impaired commercial business and commercial mortgage loans are individually evaluated and measured for impairment based on the present value of expected future cash flows discounted at the loan's effective interest rate, a loan's observable market price, or the fair value of the collateral if the loan is collateral dependent. Regardless of the measurement method, impairment is based on the fair value of the collateral when foreclosure is probable. If the recorded investment in impaired loans exceeds the measure of estimated fair value, a specific allowance is established as a component of the allowance for loan losses. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged-off when deemed uncollectible.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Company determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loans obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures unless the loan has been subject to a troubled debt restructure. At December 31, 2014, there were no commitments to lend additional funds to those borrowers whose loans were classified as impaired.
	General allowances are established for loan losses on a portfolio basis for loans that do not meet the definition of impaired. The portfolio is grouped into similar risk characteristics, primarily loan type. The Company applies an estimated loss rate, which considers both look-back and loss emergence periods, to each loan group. The loss rate is based on historical experience, with look-back periods that range from 24 to 48 months depending on the loan type, and as a result can differ from actual losses incurred in the future. The historical loss rate is adjusted by the loss emergence periods that range from 12 to 24 months depending on the loan type and for qualitative factors such as; levels and trends of delinquent and non-accruing loans, trends in volume and terms, effects of changes in lending policy, the experience, ability and depth of management, national and local economic trends and conditions, concentrations of credit risk, interest rates, highly leveraged borrowers, information risk and collateral risk. The qualitative factors are reviewed at least quarterly and adjustments are made as needed.
	While management evaluates currently available information in establishing the allowance for loan losses, future adjustments to the allowance may be necessary if conditions differ substantially from the assumptions used in making the evaluations. In addition, various regulatory agencies, as an integral part of their examination process, periodically review a financial institution's allowance for loan losses. Such agencies may require the financial institution to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.
	(i.) Other Real Estate Owned
	Other real estate owned consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the lower of fair value of the asset acquired less estimated costs to sell or "cost" (defined as the fair value at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair market value of the assets received, less estimated selling costs, is charged to the allowance for loan losses and any subsequent valuation write-downs are charged to other expense. In connection with the determination of the allowance for loan losses and the valuation of other real estate owned, management obtains appraisals for properties. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of other real estate owned are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by GAAP. The balance of other real estate owned was $194 thousand and $333 thousand at December 31, 2014 and 2013, respectively.
	(j.) Company Owned Life Insurance
	The Company holds life insurance policies on certain current and former employees. The Company is the owner and beneficiary of the policies. The cash surrender value of these policies is included as an asset on the consolidated statements of financial condition, and any increase in cash surrender value is recorded as noninterest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income.
	(k.) Premises and Equipment
	Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. The Company generally amortizes buildings and building improvements over a period of 15 to 39 years and software, furniture and equipment over a period of 3 to 10 years. Leasehold improvements are amortized over the shorter of the lease term or the useful life of the improvements. Premises and equipment are periodically reviewed for impairment or when circumstances present indicators of impairment.
	(l.) Goodwill and Other Intangible Assets
	Goodwill represents the excess of the purchase price over the fair value of net assets acquired in accordance with the purchase method of accounting for business combinations. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. GAAP requires goodwill to be tested for impairment at the Company's reporting unit level on an annual basis, which for the Company is September 30th, and more frequently if events or circumstances indicate that there may be impairment.
	Impairment exists when a reporting unit's carrying value of goodwill exceeds its implied fair value. In testing goodwill for impairment, GAAP permits the Company to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. A reporting unit is defined as any distinct, separately identifiable component of one of our operating segments for which complete, discrete financial information is available and reviewed regularly by the segment's management. If, after assessing the totality of events and circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test would be unnecessary. However, if the Company concludes otherwise, it would then be required to perform the first step (Step 1) of the goodwill impairment test, and continue to the second step (Step 2), if necessary. Step 1 compares the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, Step 2 of the goodwill impairment test is performed to measure the amount of impairment loss, if any.
	Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's intangible assets consist of core deposits and other intangible assets (primarily customer relationships). Core deposit intangible assets are amortized on an accelerated basis over their estimated life of approximately nine and a half years. Other intangible assets are amortized on an accelerated basis over their weighted average estimated life of approximately twenty years. Intangible assets with indefinite useful lives are not amortized until their lives are determined to be definite. Intangible assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. See Note 7 - Goodwill and Other Intangible Assets.
	(m.) Federal Home Loan Bank ("FHLB") and Federal Reserve Bank ("FRB") Stock
	The non-marketable investments in FHLB and FRB stock are included in other assets in the consolidated statements of financial condition at par value or cost and are periodically reviewed for impairment. The dividends received relative to these investments are included in other noninterest income in the consolidated statements of income.
	As a member of the FHLB system, the Company is required to maintain a specified investment in FHLB of New York ("FHLBNY") stock in proportion to its volume of certain transactions with the FHLB. FHLBNY stock totaled $15.1 million and $15.8 million as of December 31, 2014 and 2013, respectively.
	As a member of the FRB system, the Company is required to maintain a specified investment in FRB stock based on a ratio relative to the Company's capital. FRB stock totaled $3.9 million as of December 31, 2014 and 2013.
(n.) Equity Method Investments
The Company has investments in limited partnerships, primarily Small Business Investment Companies, and accounts for these investments under the equity method. These investments are included in other assets in the consolidated statements of financial condition and totaled $4.9 million and $4.8 million as of December 31, 2014 and 2013, respectively.
(o.) Treasury Stock
Acquisitions of treasury stock are recorded at cost. The reissuance of shares in treasury is recorded at weighted-average cost.
(p.) Employee Benefits
The Company participates in a non-contributory defined benefit pension plan for certain employees who previously met participation requirements. The Company also provides post-retirement benefits, principally health and dental care, to employees of a previously acquired entity. The Company has closed the pension and post-retirement plans to new participants. The actuarially determined pension benefit is based on years of service and the employee's highest average compensation during five consecutive years of employment. The Company's policy is to at least fund the minimum amount required by the Employment Retirement Income Security Act of 1974. The cost of the pension and post-retirement plans are based on actuarial computations of current and future benefits for employees, and is charged to noninterest expense in the consolidated statements of income.
The Company recognizes an asset or a liability for a plans' overfunded status or underfunded status, respectively, in the consolidated financial statements and reports changes in the funded status as a component of other comprehensive income, net of applicable taxes, in the year in which changes occur.
(q.) Share-Based Compensation Plans
Compensation expense for stock options and restricted stock awards is based on the fair value of the award on the measurement date, which, for the Company, is the date of grant and is recognized ratably over the service period of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model. The fair value of restricted stock awards is generally the market price of the Company's stock on the date of grant.
Share-based compensation expense is included in the consolidated statements of income under salaries and employee benefits for awards granted to management and in other noninterest expense for awards granted to directors.
(r.) Income Taxes
Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. A valuation allowance is recognized on deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the assets may not be realized. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
(s.) Comprehensive Income
Comprehensive income includes all changes in shareholders' equity during a period, except those resulting from transactions with shareholders. In addition to net income, other components of the Company's comprehensive income include the after tax effect of changes in net unrealized gain / loss on securities available for sale and changes in net actuarial gain / loss on defined benefit post-retirement plans. Comprehensive income is reported in the accompanying consolidated statements of changes in shareholder's equity and consolidated statements of comprehensive income. See Note 13 - Accumulated Other Comprehensive Income (Loss) for additional information.
(t.) Earnings Per Common Share
The Company calculates earnings per common share ("EPS") using the two-class method in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 260, "Earnings Per Share". The two-class method requires the Company to present EPS as if all of the earnings for the period are distributed to common shareholders and any participating securities, regardless of whether any actual dividends or distributions are made. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities. Certain of the restricted shares issued under the Company's share-based compensation plan are entitled to dividends at the same rate as common stock. The Company has determined that these outstanding non-vested stock awards qualify as participating securities.
Basic EPS is computed by dividing distributed and undistributed earnings available to common shareholders by the weighted average number of common shares outstanding for the period. Distributed and undistributed earnings available to common shareholders represent net income reduced by preferred stock dividends and distributed and undistributed earnings available to participating securities. Common shares outstanding include common stock and vested restricted stock awards. Diluted EPS reflects the assumed conversion of all potential dilutive securities. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 16 - Earnings Per Common Share.
(u.) Reclassifications
Certain items in prior financial statements have been reclassified to conform to the current presentation.
(v.) Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 is effective for the Company on January 1, 2017. The Company is evaluating the potential impact on the Company's financial statements.
In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718). The pronouncement was issued to clarify the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASU 2014-12 is effective for the Company beginning January 1, 2016, though early adoption is permitted. The adoption of ASU 2014-12 is not expected to have a significant impact on the Company's financial statements.
In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) –Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for the Company beginning January 1, 2016, though early adoption is permitted. ASU 2015-01 is not expected to have a significant impact on the Company's financial statements.

	SDN Acquisition
	On August 1, 2014, the Company completed the acquisition of Scott Danahy Naylon Co., Inc., a full service insurance agency located in Amherst, New York. Consideration for the acquisition included both cash and stock totaling $16.9 million, including up to $3.4 million of future payments, contingent upon SDN meeting certain revenue performance targets through 2017. The estimated fair value of the contingent consideration at the date of acquisition was $3.2 million, which was estimated using a probability-weighted discounted cash flow model. As a result of the acquisition, the Company recorded goodwill of $12.6 million and other intangible assets of $6.6 million. The goodwill is not expected to be deductible for income tax purposes. Pro forma results of operations for this acquisition have not been presented because the effect of this acquisition was not material to the Company's consolidated financial statements.
	This acquisition was accounted for under the acquisition method in accordance with FASB ASC Topic 805. Accordingly, the assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the acquisition date. Due to the timing of the closing of the acquisition, the fair values of other intangibles recorded are subject to adjustment as additional information becomes available to indicate a more accurate or appropriate fair value for the intangibles during the measurement period, which is not to exceed one year from the acquisition date.
	The following table summarizes the consideration paid for Scott Danahy Naylon Co., Inc. and the amounts of the assets acquired and liabilities assumed.

	During the year ended December 31, 2014, the Company transferred $12.8 million of available for sale mortgage backed securities to the held to maturity category, reflecting the Company's intent to hold those securities to maturity. Transfers of investment securities into the held to maturity category from the available for sale category are made at fair value at the date of transfer. The related $51 thousand of unrealized holding losses that were included in the transfer are retained in accumulated other comprehensive income and in the carrying value of the held to maturity securities. This amount will be amortized as an adjustment to interest income over the remaining life of the securities. This will offset the impact of amortization of the net premium created in the transfer.

The total number of security positions in the investment portfolio in an unrealized loss position at December 31, 2014 was 122 compared to 331 at December 31, 2013. At December 31, 2014, the Company had positions in 51 investment securities with a fair value of $207.9 million and a total unrealized loss of $5.7 million that have been in a continuous unrealized loss position for more than 12 months. There were a total of 71 securities positions in the Company's investment portfolio, with a fair value of $69.9 million and a total unrealized loss of $236 thousand at December 31, 2014, that have been in a continuous unrealized loss position for less than 12 months. At December 31, 2013, the Company had positions in 14 investment securities with a fair value of $50.9 million and a total unrealized loss of $2.8 million that have been in a continuous unrealized loss position for more than 12 months. There were a total of 317 securities positions in the Company's investment portfolio, with a fair value of $407.3 million and a total unrealized loss of $15.2 million at December 31, 2013, that have been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of most of the investment securities in the Company's portfolio fluctuates as market interest rates change.
The Company reviews investment securities on an ongoing basis for the presence of other than temporary impairment ("OTTI") with formal reviews performed quarterly. When evaluating debt securities for OTTI, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intention to sell the debt security or whether it is more likely than not that it will be required to sell the debt security before its anticipated recovery. The assessment of whether OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management.
No impairment was recorded during the years ended December 31, 2014 and 2013. During the year ended December 31, 2012, the Company recognized an OTTI charge of $91 thousand related to privately issued whole loan CMOs that were determined to be impaired due to credit quality.
Based on management's review and evaluation of the Company's debt securities as of December 31, 2014, the debt securities with unrealized losses were not considered to be OTTI. As of December 31, 2014, the Company does not have the intent to sell any of the securities in a loss position and believes that it is not likely that it will be required to sell any such securities before the anticipated recovery of amortized cost. Accordingly, as of December 31, 2014, management has concluded that unrealized losses on its investment securities are temporary and no further impairment loss has been realized in the Company's consolidated statements of income.

	The Company's significant concentrations of credit risk in the loan portfolio relate to a geographic concentration in the communities that the Company serves.
	Certain executive officers, directors and their business interests are customers of the Company. Transactions with these parties are based on the same terms as similar transactions with unrelated third parties and do not carry more than normal credit risk. Borrowings by these related parties amounted to $11.9 million and $2.9 million at December 31, 2014 and 2013, respectively. During 2014, new borrowings amounted to $10.0 million (including borrowings of executive officers and directors that were outstanding at the time of their appointment), and repayments and other reductions were $1.0 million.

	There were no loans past due greater than 90 days and still accruing interest as of December 31, 2014 and December 31, 2013. There were $8 thousand and $6 thousand in consumer overdrafts which were past due greater than 90 days as of December 31, 2014 and December 31, 2013, respectively. Consumer overdrafts are overdrawn deposit accounts which have been reclassified as loans but by their terms do not accrue interest.
	Interest income on nonaccrual loans, if recognized, is recorded using the cash basis method of accounting. There was no interest income recognized on nonaccrual loans during the years ended December 31, 2014, 2013 and 2012. For the years ended December 31, 2014, 2013 and 2012, estimated interest income of $527 thousand, $531 thousand, and $555 thousand, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms.
	Troubled Debt Restructurings
	A modification of a loan constitutes a troubled debt restructuring ("TDR") when a borrower is experiencing financial difficulty and the modification constitutes a concession. The Company offers various types of concessions when modifying loans, however, forgiveness of principal is rarely granted. Commercial loans modified in a TDR may involve temporary interest-only payments, term extensions, reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, requesting additional collateral, releasing collateral for consideration, or substituting or adding a new borrower or guarantor.
	The following presents, by loan class, information related to loans modified in a TDR during the years ended December 31 (in thousands).
				Pre-		Post-
				Modification		Modification

Commercial mortgage	2		7,335		6,935
Total	6	$	8,800	$	8,391
With the exception of one commercial mortgage loan modified during 2013, all of the loans identified as TDRs by the Company during the years ended December 31, 2014 and 2013 were on nonaccrual status and reported as impaired loans prior to restructuring. For the year ended December 31, 2014, the restructured loan modification related to extending the amortization period of the loan. For the year ended December 31, 2013, restructured loan modifications of commercial business and commercial mortgage loans primarily included maturity date extensions, payment schedule modifications and forgiveness of principal. All loans restructured during the years ended December 31, 2014 and 2013 were on nonaccrual status at the end of those respective years. Nonaccrual loans that are restructured remain on nonaccrual status, but may move to accrual status after they have performed according to the restructured terms for a period of time. The TDR classification did not have a material impact on the Company's determination of the allowance for loan losses because the modified loans were either classified as substandard, with an increased risk allowance allocation, or impaired and evaluated for a specific reserve both before and after restructuring.
For purposes of this disclosure, a loan modified as a TDR is considered to have defaulted when the borrower becomes 90 days past due. There were no loans modified as a TDR during the previous 12 months which subsequently defaulted during the years ended December 31, 2014 and 2013.
Impaired Loans
Management has determined that specific commercial loans on nonaccrual status and all loans that have had their terms restructured in a troubled debt restructuring are impaired loans. The following table presents data on impaired loans at December 31 (in thousands):

Credit Quality Indicators
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors such as the fair value of collateral. The Company analyzes commercial business and commercial mortgage loans individually by classifying the loans as to credit risk. Risk ratings are updated any time the situation warrants. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company's credit position at some future date.
Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Loans not meeting the criteria above that are analyzed individually as part of the process described above are considered "Uncriticized" or pass-rated loans and are included in groups of homogeneous loans with similar risk and loss characteristics.
The following table sets forth the Company's commercial loan portfolio, categorized by internally assigned asset classification, as of December 31 (in thousands):

The Company utilizes payment status as a means of identifying and reporting problem and potential problem retail loans. The Company considers nonaccrual loans and loans past due greater than 90 days and still accruing interest to be non-performing.

Risk Characteristics
Commercial business loans primarily consist of loans to small to mid-sized businesses in our market area in a diverse range of industries. These loans are of higher risk and typically are made on the basis of the borrower's ability to make repayment from the cash flow of the borrower's business. Further, the collateral securing the loans may depreciate over time, may be difficult to appraise and may fluctuate in value. The credit risk related to commercial loans is largely influenced by general economic conditions and the resulting impact on a borrower's operations or on the value of underlying collateral, if any.
Commercial mortgage loans generally have larger balances and involve a greater degree of risk than residential mortgage loans, inferring higher potential losses on an individual customer basis. Loan repayment is often dependent on the successful operation and management of the properties, as well as on the collateral securing the loan. Economic events or conditions in the real estate market could have an adverse impact on the cash flows generated by properties securing the Company's commercial real estate loans and on the value of such properties.
Residential mortgage loans and home equities (comprised of home equity loans and home equity lines) are generally made on the basis of the borrower's ability to make repayment from his or her employment and other income, but are secured by real property whose value tends to be more easily ascertainable. Credit risk for these types of loans is generally influenced by general economic conditions, the characteristics of individual borrowers, and the nature of the loan collateral.
Consumer indirect and other consumer loans may entail greater credit risk than residential mortgage loans and home equities, particularly in the case of other consumer loans which are unsecured or, in the case of indirect consumer loans, secured by depreciable assets, such as automobiles or boats. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower's continuing financial stability, and thus are more likely to be affected by adverse personal circumstances such as job loss, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.

Goodwill And Other Intangible Assets	(7.) GOODWILL AND OTHER INTANGIBLE ASSETS
	The change in the balance for goodwill during the years ended December 31 was as follows (in thousands):
			2014		2013
	Goodwill, beginning of year	$	48,536	$	48,536
	Addition from the SDN acquisition		12,617		-
	Goodwill, end of year	$	61,153	$	48,536
	Goodwill and other intangible assets added during the period relates to the SDN acquisition, which closed on August 1, 2014. See Note 2 – Business Combinations for additional information.
	The Company performed a qualitative assessment of goodwill to determine if it was more likely than not that the fair value of the reporting unit is less than its carrying value. In performing a qualitative analysis, factors considered include, but are not limited to, business strategy, financial performance and market and regulatory dynamics. The results of the qualitative assessment for 2014 and 2013 indicated that it was not more likely than not that the fair value of the reporting unit is less than its carrying value. Consequently, no additional quantitative two-step impairment test was required, and no impairment was recorded in 2014 or 2013. In 2012, prior to the adoption of ASU 2011-08, the Company performed a quantitative impairment test that did not result in any impairment.
	Declines in the market value of the Company's publicly traded stock price or declines in the Company's ability to generate future cash flows may increase the potential that goodwill recorded on the Company's consolidated statement of financial condition be designated as impaired and that the Company may incur a goodwill write-down in the future.
	The Company has other intangible assets that are amortized, consisting of core deposit intangibles and other intangibles (primarily related to customer relationships acquired in connection with the Company's insurance agency acquisition). Changes in the gross carrying amount, accumulated amortization and net book value for the years ended December 31 were as follows (in thousands):
			2014			2013
	Core deposit intangibles:

Short-term FHLB borrowings at December 31, 2014 consisted of $129.0 million in overnight borrowings and $166.3 million in short-term advances. Short-term FHLB borrowings at December 31, 2013 consisted of $198.0 million in overnight borrowings and $100.0 million in short-term advances. The FHLB borrowings are collateralized by securities from the Company's investment portfolio and certain qualifying loans.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	(10.) COMMITMENTS AND CONTINGENCIES
	Financial Instruments with Off-Balance Sheet Risk
	The Company has financial instruments with off-balance sheet risk established in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk extending beyond amounts recognized in the financial statements.
	The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is essentially the same as that involved with extending loans to customers. The Company uses the same credit underwriting policies in making commitments and conditional obligations as for on-balance sheet instruments.
	Off-balance sheet commitments as of December 31 consist of the following (in thousands):
			2014		2013
	Commitments to extend credit	$	450,343	$	431,236
	Standby letters of credit		8,578		8,618
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Commitments may expire without being drawn upon; therefore the total commitment amounts do not necessarily represent future cash requirements. Each customer's creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if any, is based on management's credit evaluation of the borrower. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support private borrowing arrangements. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers.
	The Company also extends rate lock agreements to borrowers related to the origination of residential mortgage loans. To mitigate the interest rate risk inherent in these rate lock agreements when the Company intends to sell the related loan, once originated, as well as closed residential mortgage loans held for sale, the Company enters into forward commitments to sell individual residential mortgages. Rate lock agreements and forward commitments are considered derivatives and are recorded at fair value. Forward sales commitments totaled $1.2 million at December 31, 2014. There were no forward sales commitments outstanding as of December 31, 2013. The net change in the fair values of these derivatives was recognized as other noninterest income or other noninterest expense in the consolidated statements of income.
	Lease Obligations
	The Company is obligated under a number of noncancellable operating lease agreements for land, buildings and equipment. Certain of these leases provide for escalation clauses and contain renewal options calling for increased rentals if the lease is renewed. Future minimum payments by year and in the aggregate, under the noncancellable leases with initial or remaining terms of one year or more, are as follows at December 31, 2014 (in thousands):
	2015	$	1,673
	2016		1,576
	2017		1,203
	2018		952
	2019		876
	Thereafter		3,788
		$	10,068
	Rent expense relating to these operating leases, included in occupancy and equipment expense in the statements of income, was $1.8 million, $1.7 million and $1.6 million in 2014, 2013 and 2012, respectively.
	Contingent Liabilities
	In the ordinary course of business there are various threatened and pending legal proceedings against the Company. Based on consultation with outside legal counsel, management believes that the aggregate liability, if any, arising from such litigation would not have a material adverse effect on the Company's consolidated financial statements.

Regulatory Matters [Abstract]
Regulatory Matters	(11.) REGULATORY MATTERS
	General
	The supervision and regulation of financial and bank holding companies and their subsidiaries is intended primarily for the protection of depositors, the deposit insurance funds regulated by the FDIC and the banking system as a whole, and not for the protection of shareholders or creditors of bank holding companies. The various bank regulatory agencies have broad enforcement power over financial holding companies and banks, including the power to impose substantial fines, operational restrictions and other penalties for violations of laws and regulations and for safety and soundness considerations.
	Capital
	Banks and financial holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material impact on the Company's consolidated financial statements. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets (all as defined in the regulations). These minimum amounts and ratios are included in the table below.
	The Company's and the Bank's Tier 1 capital consists of shareholders' equity excluding unrealized gains and losses on securities available for sale (except for unrealized losses which have been determined to be other than temporary and recognized as expense in the consolidated statements of income), goodwill and other intangible assets and disallowed portions of deferred tax assets. Tier 1 capital for the Company includes, subject to limitation, $17.3 million of preferred stock. The Company and the Bank's total capital are comprised of Tier 1 capital for each entity plus a permissible portion of the allowance for loan losses.
	The Tier 1 and total risk-based capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, excluding goodwill and other intangible assets and disallowed portions of deferred tax assets, allocated by risk weight category and certain off-balance-sheet items (primarily loan commitments). The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets and disallowed portions of deferred tax assets.
	The Company's and the Bank's actual and required regulatory capital ratios were as follows as of December 31 (in thousands):
								For Capital
				Actual				Adequacy Purposes				Well Capitalized
				Amount	Ratio			Amount	Ratio			Amount	Ratio
	2014
	Tier 1 leverage:	Company	$	219,904	7.35	%	$	119,722	4	%	$	149,653	5	%
		Bank		215,672	7.21			119,671	4			149,588	5
	Tier 1 capital:	Company		219,904	10.47			83,985	4			125,977	6
		Bank		215,672	10.28			83,889	4			125,834	6
	Total risk-based capital:	Company		246,166	11.72			167,970	8			209,962	10
		Bank		241,905	11.53			167,779	8			209,723	10
	2013
	Tier 1 leverage:	Company	$	215,024	7.63	%	$	112,660	4	%	$	140,825	5	%
		Bank		204,336	7.27			112,498	4			140,622	5
	Tier 1 capital:	Company		215,024	10.82			79,459	4			119,188	6
		Bank		204,336	10.31			79,291	4			118,937	6
	Total risk-based capital:	Company		239,878	12.08			158,918	8			198,647	10
		Bank		229,139	11.56			158,583	8			198,228	10
	As of December 31, 2014, the Company and Bank were considered "well capitalized" under all regulatory capital guidelines. Such determination has been made based on the Tier 1 leverage, Tier 1 capital and total risk-based capital ratios.
	Federal Reserve Requirements
	The Bank was not required to maintain a reserve balance at the FRB of New York as of December 31, 2014. The reserve requirement was $1.0 million as of December 31, 2013.
	Dividend Restrictions
	In the ordinary course of business, the Company is dependent upon dividends from the Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years.

Share-Based Compensation Plans [Abstract]
Share-Based Compensation Plans	(14.) SHARE-BASED COMPENSATION
	The Company maintains certain stock-based compensation plans, approved by the Company's shareholders that are administered by the Board, or the Management Development and Compensation Committee (the "Compensation Committee") of the Board. In May 2009, the shareholders of the Company approved two share-based compensation plans, the 2009 Management Stock Incentive Plan ("Management Plan") and the 2009 Directors' Stock Incentive Plan ("Director's Plan"), and collectively with the Management Plan, "the Plans". An aggregate of 690,000 shares of the Company's common stock have been reserved for issuance by the Company under the terms of the Management Plan pursuant to the grant of incentive stock options (not to exceed 500,000 shares), non-qualified stock options and restricted stock grants, all of which are defined in the plan. An aggregate of 250,000 shares of the Company's common stock have been reserved for issuance by the Company under the terms of the Director's Plan pursuant to the grant of non-qualified stock options and restricted stock grants, all of which are defined in the plan. Under both plans, for purposes of calculating the number of shares of common stock available for issuance, each share of common stock granted pursuant to a restricted stock grant counts as 1.64 shares of the Company's common stock. As of December 31, 2014, there were approximately 119,000 and 396,000 shares available for grant under the Director's Plan and Management Plan, respectively, of which 61% were available for issuance as restricted stock grants.
	Under the Plans, the Board, in the case of the Director's Plan, or the Compensation Committee, in the case of the Management Plan, may establish and prescribe grant guidelines including various terms and conditions for the granting of stock-based compensation. For stock options, the exercise price of each option equals the market price of the Company's stock on the date of the grant. All options expire after a period of ten years from the date of grant and generally become fully exercisable over a period of 3 to 5 years from the grant date. When an option recipient exercises their options, the Company issues shares from treasury stock and records the proceeds as additions to capital. Shares of restricted stock granted to employees generally vest over 2 to 3 years from the grant date. Fifty percent of the shares of restricted stock granted to non-employee directors generally vests on the date of grant and the remaining fifty percent generally vests one year from the grant date. Vesting of the shares may be based on years of service, established performance measures or both. If restricted stock grants are forfeited before they vest, the shares are reacquired into treasury stock.
	The share-based compensation plans were established to allow for the granting of compensation awards to attract, motivate and retain employees, executive officers and non-employee directors who contribute to the success and profitability of the Company and to give such persons a proprietary interest in the Company, thereby enhancing their personal interest in the Company's success.
	The Company awarded grants of 22,642 shares of restricted common stock to certain members of management during the year ended December 31, 2014. Fifty percent of the shares subject to each grant will be earned based upon achievement of an EPS performance requirement for the Company's fiscal year ended December 31, 2014. The remaining fifty percent of the shares will be earned based on the Company's achievement of a relative total shareholder return ("TSR") performance requirement, on a percentile basis, compared to a defined group of peer companies over a three-year performance period ended December 31, 2016. The shares earned based on the achievement of the EPS and TSR performance requirements, if any, will vest based on the recipient's continuous service to the Company on February 17, 2017.
	The grant date fair value of the TSR portion of the award granted during the year ended December 31, 2014 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.87 years, (ii) risk free interest rate of 0.62%, (iii) expected dividend yield of 3.59% and (iv) expected stock price volatility over the expected term of the TSR award of 39.4%. The model resulted in a grant date fair value of $10.54 for the TSR portion of the award. The grant date fair value of all other restricted stock awards is equal to the closing market price of our common stock on the date of grant.
	In addition, the Company granted 11,600 shares of restricted common stock to management during the year ended December 31, 2014. The shares will vest after completion of a three-year service requirement. The weighted average market price of the restricted stock awards on the date of grant was $21.26.
	During the year ended December 31, 2014, the Company granted 9,000 restricted shares of common stock to directors, of which 4,500 shares vested immediately and 4,500 shares will vest after completion of a one-year service requirement. The market price of the restricted stock on the date of grant was $22.82.
	The restricted stock awards granted to management and directors in 2014 do not have rights to dividends or dividend equivalents until vested.
	The Company uses the Black-Scholes valuation method to estimate the fair value of its stock option awards. There were no stock options awarded during 2014, 2013 or 2012. There was no unrecognized compensation expense related to unvested stock options as of December 31, 2014. The following is a summary of stock option activity for the year ended December 31, 2014 (dollars in thousands, except per share amounts):

	The aggregate intrinsic value (the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant) of option exercises for the years ended December 31, 2014, 2013 and 2012 was $161 thousand, $106 thousand, and $10 thousand, respectively. The total cash received as a result of option exercises under stock compensation plans for the years ended December 31, 2014, 2013 and 2012 was $667 thousand, $448 thousand, and $69 thousand, respectively. The tax benefits realized in connection with these stock option exercises were not significant.
	The following is a summary of restricted stock award activity for the year ended December 31, 2014:

	Outstanding at end of period	59,113		$	17.24
	As of December 31, 2014, there was $488 thousand of unrecognized compensation expense related to unvested restricted stock awards that is expected to be recognized over a weighted average period of 1.8 years.
	The Company amortizes the expense related to restricted stock awards over the vesting period. Share-based compensation expense is recorded as a component of salaries and employee benefits in the consolidated statements of income for awards granted to management and as a component of other noninterest expense for awards granted to directors. The share-based compensation expense for the years ended December 31 was as follows (in thousands):

	Shareholder's equity		925		(8,817	)		1,514
	The Company recognizes deferred income taxes for the estimated future tax effects of differences between the tax and financial statement bases of assets and liabilities considering enacted tax laws. These differences result in deferred tax assets and liabilities, which are included in other assets in the Company's consolidated statements of condition. The Company also assesses the likelihood that deferred tax assets will be realizable based on, among other considerations, future taxable income and establishes, if necessary, a valuation allowance for those deferred tax assets determined to not likely be realizable. A deferred tax asset valuation allowance is recognized if, based on the weight of available evidence (both positive and negative), it is more likely than not that some portion or all of the deferred tax assets will not be realized. The future realization of deferred tax benefits depends upon the existence of sufficient taxable income within the carry-back and carry-forward periods. Management's judgment is required in determining the appropriate recognition of deferred tax assets and liabilities, including projections of future taxable income.
	The Company's net deferred tax asset is included in other assets in the consolidated statements of condition. The tax effects of temporary differences that give rise to the deferred tax assets and deferred tax liabilities are as follows at December 31 (in thousands):
			2014		2013

	In March 2014, the New York legislature approved changes in the state tax law that will be phased-in over two years, beginning in 2015. The primary changes that impact us include the repeal of the Article 32 franchise tax on banking corporations ("Article 32A") for 2015, expanded nexus standards for 2015 and a reduction in the corporate tax rate for 2016. The Company expects the repeal of Article 32A and the expanded nexus standards to lower our taxable income apportioned to New York to 85% in 2015 from 100% in 2014. In addition, the New York state income tax rate will be reduced from 7.1% to 6.5% in 2016. The lower New York state taxes going forward reduced the benefit provided by existing deferred tax items, consequently the Company revalued its deferred tax assets as of December 31, 2014, which did not have a material impact on the consolidated statements of income and condition.
	Based upon the Company's historical and projected future levels of pre-tax and taxable income, the scheduled reversals of taxable temporary differences to offset future deductible amounts, and prudent and feasible tax planning strategies, management believes it is more likely than not that the deferred tax assets will be realized. As such, no valuation allowance has been recorded as of December 31, 2014 or 2013.
	The Company and its subsidiaries are primarily subject to federal and New York State ("NYS") income taxes. The federal income tax years currently open for audit are 2013 and 2014. The NYS income tax years currently open for audit are 2011 through 2014.
	At December 31, 2014, the Company had no federal or NYS net operating loss carryforwards. The Company has NYS tax credits of approximately $900 thousand which have an unlimited carryforward period.
	The Company's unrecognized tax benefits and changes in unrecognized tax benefits were not significant as of or for the years ended December 31, 2014, 2013 and 2012. There were no interest or penalties recorded in the income statement in income tax expense for the year ended December 31, 2014. As of December 31, 2014 and 2013, there were no amounts accrued for interest or penalties related to uncertain tax positions.

Employee Benefit Plans	(17.) EMPLOYEE BENEFIT PLANS
	Defined Benefit Pension Plan
	The Company participates in The New York State Bankers Retirement System (the "Plan"), a defined benefit pension plan covering substantially all employees, subject to the limitations related to the plan closure effective December 31, 2006. The benefits are based on years of service and the employee's highest average compensation during five consecutive years of employment. The defined benefit plan was closed to new participants effective December 31, 2006. Only employees hired on or before December 31, 2006 and who met participation requirements on or before January 1, 2008 are eligible to receive benefits.
	The following table provides a reconciliation of the Company's changes in the plan's benefit obligations, fair value of assets and a statement of the funded status as of and for the year ended December 31 (in thousands):
			2014			2013
	Change in projected benefit obligation:
	Projected benefit obligation at beginning of period	$	48,991		$	53,625
	Service cost		1,918			2,063

	Fair value of plan assets at end of period		75,584			64,603
	Funded status at end of period	$	13,852		$	15,612
	The accumulated benefit obligation was $54.9 million and $44.0 million at December 31, 2014 and 2013, respectively.
	The Company's funding policy is to contribute, at a minimum, an actuarially determined amount that will satisfy the minimum funding requirements determined under the appropriate sections of Internal Revenue Code. The Company had no minimum required contribution for the 2015 fiscal year, but for tax purposes chose to contribute $8.0 million to its pension plan prior to December 31, 2014.
	Estimated benefit payments under the pension plan over the next ten years at December 31, 2014 are as follows (in thousands):
	2015	$	1,860
	2016		2,086
	2017		2,264
	2018		2,330
	2019		2,470
	2020 - 2024		14,856
	Net periodic pension cost consists of the following components for the years ended December 31 (in thousands):
			2014			2013			2012
	Service cost	$	1,918		$	2,063		$	2,037
	Interest cost on projected benefit obligation		2,291			2,017			2,017
	Expected return on plan assets		(4,117	)		(3,684	)		(3,211	)
	Amortization of unrecognized loss		159			1,344			1,370
	Amortization of unrecognized prior service cost		20			20			20
	Net periodic pension cost	$	271		$	1,760		$	2,233
	The actuarial assumptions used to determine the net periodic pension cost were as follows:
		2014		2013		2012
	Weighted average discount rate	4.8	%	3.84	%	4.27	%
	Rate of compensation increase	3	%	3	%	3	%
	Expected long-term rate of return	6.5	%	6.5	%	7	%
	The actuarial assumptions used to determine the projected benefit obligation were as follows:
		2014		2013		2012
	Weighted average discount rate	3.86	%	4.8	%	3.84	%
	Rate of compensation increase	3	%	3	%	3	%
	The weighted average discount rate was based upon the projected benefit cash flows and the market yields of high grade corporate bonds that are available to pay such cash flows.
	The weighted average expected longterm rate of return is estimated based on current trends in the Plan's assets as well as projected future rates of return on those assets and reasonable actuarial assumptions based on the guidance provided by Actuarial Standard of Practice No. 27, "Selection of Economic Assumptions for Measuring Pension Obligations" for long term inflation, and the real and nominal rate of investment return for a specific mix of asset classes. The following assumptions were used in determining the longterm rate of return:
	Equity securities	Dividend discount model, the smoothed earnings yield model and the equity risk premium model
	Fixed income securities	Current yieldtomaturity and forecasts of future yields
	Other financial instruments	Comparison of the specific investment's risk to that of fixed income and equity instruments and using judgment
	The long term rate of return considers historical returns. Adjustments were made to historical returns in order to reflect expectations of future returns. These adjustments were due to factor forecasts by economists and longterm U.S. Treasury yields to forecast longterm inflation. In addition forecasts by economists and others for longterm GDP growth were factored into the development of assumptions for earnings growth and per capita income.
	The Plan's overall investment strategy is to achieve a mix of approximately 97% of investments for long-term growth and 3% for near-term benefit payments with a wide diversification of asset types, fund strategies, and fund managers. The target allocations for Plan assets are shown in the table below. Cash equivalents consist primarily of government issues (maturing in less than three months) and short term investment funds. Equity securities primarily include investments in common stock, depository receipts, preferred stock, commingled pension trust funds, exchange traded funds and real estate investment trusts. Fixed income securities include corporate bonds, government issues, mortgage backed securities, municipals, commingled pension trust funds and other asset backed securities.
	Effective February 2012, the Plan revised its investment guidelines. The Plan currently prohibits its investment managers from purchasing any security greater than 5% of the portfolio at the time of purchase or greater than 8% at market value in any one issuer. Effective June 2013, the issuer of any security purchased must be located in a country in the Morgan Stanley Capital International World Index. In addition, the following are prohibited:
	Equity securities	Short sales
		Unregistered securities
		Margin purchases
	Fixed income securities	Mortgage backed derivatives that have an inverse floating rate coupon or that are interest only securities
		Any ABS that is not issued by the U.S. Government or its agencies or its instrumentalities
		Generally securities of less than Baa2/BBB quality may not be purchased
		Securities of less than A-quality may not in the aggregate exceed 13% of the investment manager's portfolio.
		An investment manager's portfolio of commercial MBS and ABS shall not exceed 10% of the portfolio at the time of purchase.
	Other financial instruments	Unhedged currency exposure in countries not defined as "high income economies" by the World Bank
	All other investments not prohibited by the Plan are permitted. At December 31, 2014 and 2013, the Plan held certain investments which are no longer deemed acceptable to acquire. These positions will be liquidated when the investment managers deem that such liquidation is in the best interest of the Plan.
	The target allocation range below is both historic and prospective in that it has not changed since prior to 2013. It is the asset allocation range that the investment managers have been advised to adhere to and within which they may make tactical asset allocation decisions.

Assets are segregated by the level of the valuation inputs within the fair value hierarchy established by ASC Topic 820 utilized to measure fair value (see Note 18 - Fair Value Measurements). There were no assets classified as Level 3 assets during the years ended December 31, 2014 and 2013.
In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Investments valued using the NAV (Net Asset Value) are classified as level 2 if the Plan can redeem its investment with the investee at the NAV at the measurement date. If the Plan can never redeem the investment with the investee at the NAV, it is considered a level 3. If the Plan can redeem the investment at the NAV at a future date, the Plan's assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset.
The Plan uses the Thomson Reuters Pricing Service to determine the fair value of equities excluding commingled pension trust funds, the pricing service of IDC Corporate USA to determine the fair value of fixed income securities excluding commingled pension trust funds and JP Morgan Chase Bank, N.A. to determine the fair value of commingled pension trust funds. The major categories of Plan assets measured at fair value on a recurring basis as of December 31 are presented in the following table (in thousands).

A portfolio concentration in the State Street Bank & Trust Co. Short Term Investment Fund of 5% existed at December 31, 2013.
Postretirement Benefit Plan
An entity acquired by the Company provided health and dental care benefits to retired employees who met specified age and service requirements through a postretirement health and dental care plan in which both the acquired entity and the retirees shared the cost. The plan provided for substantially the same medical insurance coverage as for active employees until their death and was integrated with Medicare for those retirees aged 65 or older. In 2001, the plan's eligibility requirements were amended to curtail eligible benefit payments to only retired employees and active employees who had already met the then-applicable age and service requirements under the Plan. In 2003, retirees under age 65 began contributing to health coverage at the same cost-sharing level as that of active employees. Retirees ages 65 or older were offered new Medicare supplemental plans as alternatives to the plan historically offered. The cost sharing of medical coverage was standardized throughout the group of retirees aged 65 or older. In addition, to be consistent with the administration of the Company's dental plan for active employees, all retirees who continued dental coverage began paying the full monthly premium. The accrued liability included in other liabilities in the consolidated statements of financial condition related to this plan amounted to $124 thousand and $93 thousand as of December 31, 2014 and 2013, respectively. The postretirement expense for the plan that was included in salaries and employee benefits in the consolidated statements of income was not significant for the years ended December 31, 2014, 2013 and 2012. The plan is not funded.

Defined Contribution Plan
Employees that meet specified eligibility conditions are eligible to participate in the Company sponsored 401(k) plan. Under the plan, participants may make contributions, in the form of salary deferrals, up to the maximum Internal Revenue Code limit. The Company matches a participant's contributions up to 4.5% of compensation, calculated at 100% of the first 3% of compensation and 50% of the next 3% of compensation deferred by the participant. The Company may also make additional discretionary matching contributions, although no such additional discretionary contributions were made in 2014, 2013 or 2012. The expense included in salaries and employee benefits in the consolidated statements of income for this plan amounted to $1.1 million in 2014 and 2013 and $1.0 million in 2012.

Fair Value Measurements [Abstract]
Fair Value Measurements	(18.) FAIR VALUE MEASUREMENTS
	Determination of Fair Value – Assets Measured at Fair Value on a Recurring and Nonrecurring Basis Valuation Hierarchy
	The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820, "Fair Value Measurements and Disclosures," establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
	Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
	Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
	Level 3 - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the company's creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.
	Securities available for sale: Securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things.
	Loans held for sale: The fair value of loans held for sale is determined using quoted secondary market prices and investor commitments. Loans held for sale are classified as Level 2 in the fair value hierarchy.
	Collateral dependent impaired loans: Fair value of impaired loans with specific allocations of the allowance for loan losses is measured based on the value of the collateral securing these loans and is classified as Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable and collateral value is determined based on appraisals performed by qualified licensed appraisers hired by the Company. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised and reported values may be 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 client and the client's business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above.
	Loan servicing rights: Loan servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of loan servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The assumptions used in the discounted cash flow model are those that we believe market participants would use in estimating future net servicing income, including estimates of loan prepayment rates, servicing costs, ancillary income, impound account balances, and discount rates. The significant unobservable inputs used in the fair value measurement of the Company's loan servicing rights are the constant prepayment rates and weighted average discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they will generally move in opposite directions. Loan servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation.
	Other real estate owned (Foreclosed assets): Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. 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 client and client's business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized.
	Commitments to extend credit and letters of credit: Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value. The fair value of commitments is not material.
	Assets Measured at Fair Value
	The following table presents for each of the fair-value hierarchy levels the Company's assets that are measured at fair value on a recurring and non-recurring basis as of December 31 (in thousands):

Disclosures about Fair Value of Financial Instruments
The assumptions used below are expected to approximate those that market participants would use in valuing these financial instruments.
Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of timing, amount of expected future cash flows and the credit standing of the issuer. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In some cases, the fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below.
The estimated fair value approximates carrying value for cash and cash equivalents, FHLB and FRB stock, accrued interest receivable, non-maturity deposits, short-term borrowings and accrued interest payable. Fair value estimates for other financial instruments not included elsewhere in this disclosure are discussed below.
Securities held to maturity: The fair value of the Company's investment securities held to maturity is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things.
Loans: The fair value of the Company's loans was estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made for the same remaining maturities. Loans were first segregated by type such as commercial, residential mortgage, and consumer, and were then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments.
Time deposits: The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company's time deposit liabilities do not take into consideration the value of the Company's long-term relationships with depositors, which may have significant value.
The following presents the carrying amount, estimated fair value, and placement in the fair value measurement hierarchy of the Company's financial instruments as of December 31(in thousands):

Summary Of Significant Accounting Policies [Abstract]
Principles Of Consolidation	(a.) Principles of Consolidation
	The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use Of Estimates	(b.) Use of Estimates
	In preparing the consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the statement of financial condition and reported amounts of revenue and expenses during the reporting period. Material estimates relate to the determination of the allowance for loan losses, the carrying value of goodwill and deferred tax assets, the valuation and other than temporary impairment ("OTTI") considerations related to the securities portfolio, and assumptions used in the defined benefit pension plan accounting. These estimates and assumptions are based on management's best estimates and judgment and are evaluated on an ongoing basis using historical experience and other factors, including the current economic environment. The Company adjusts these estimates and assumptions when facts and circumstances dictate. As future events cannot be determined with precision, actual results could differ significantly from the Company's estimates.
Cash Flow Reporting	(c.) Cash Flow Reporting
	Cash and cash equivalents include cash and due from banks, federal funds sold and interest-bearing deposits in other banks. Net cash flows are reported for loans, deposit transactions and short-term borrowings.

Investment Securities	(d.) Investment Securities
	Investment securities are classified as either available for sale or held to maturity. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and are recorded at amortized cost. Other investment securities are classified as available for sale and recorded at fair value, with unrealized gains and losses excluded from earnings and reported as a component of comprehensive income and shareholders' equity.
	Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Securities are evaluated periodically to determine whether a decline in their fair value is other than temporary. Management utilizes criteria such as, the current intent to hold or sell the security, the magnitude and duration of the decline and, when appropriate, consideration of negative changes in expected cash flows, creditworthiness, near term prospects of issuers, the level of credit subordination, estimated loss severity, and delinquencies, to determine whether a loss in value is other than temporary. The term "other than temporary" is not intended to indicate that the decline is permanent, but indicates that the prospect for a near-term recovery of value is not necessarily favorable. Declines in the fair value of investment securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit issues or concerns, or the security is intended to be sold. The amount of impairment related to non-credit related factors is recognized in other comprehensive income. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Loans Held For Sale And Loan Servicing Rights	(e.) Loans Held for Sale and Loan Servicing Rights
	The Company generally makes the determination of whether to identify a mortgage as held for sale at the time the loan is closed based on the Company's intent and ability to hold the loan. Loans held for sale are recorded at the lower of cost or market computed on the aggregate portfolio basis. The amount, by which cost exceeds market value, if any, is accounted for as a valuation allowance with changes included in the determination of results of operations for the period in which the change occurs. The amount of loan origination cost and fees are deferred at origination of the loans and recognized as part of the gain or loss on sale of the loans, determined using the specific identification method, in the consolidated statements of income.
	The Company originates and sells certain residential real estate loans in the secondary market. The Company typically retains the right to service the mortgages upon sale. Mortgage-servicing rights ("MSRs") represent the cost of acquiring the contractual rights to service loans for others. MSRs are recorded at their fair value at the time a loan is sold and servicing rights are retained. MSRs are reported in other assets in the consolidated statements of financial position and are amortized to noninterest income in the consolidated statements of income in proportion to and over the period of estimated net servicing income. The Company uses a valuation model that calculates the present value of future cash flows to determine the fair value of servicing rights. In using this valuation method, the Company incorporates assumptions to estimate future net servicing income, which include estimates of the cost to service the loan, the discount rate, an inflation rate and prepayment speeds. On a quarterly basis, the Company evaluates its MSRs for impairment and charges any such impairment to current period earnings. In order to evaluate its MSRs the Company stratifies the related mortgage loans on the basis of their predominant risk characteristics, such as interest rates, year of origination and term, using discounted cash flows and market-based assumptions. Impairment of MSRs is recognized through a valuation allowance, determined by estimating the fair value of each stratum and comparing it to its carrying value. Subsequent increases in fair value are adjusted through the valuation allowance, but only to the extent of the valuation allowance.
	Mortgage loan servicing includes collecting monthly mortgagor payments, forwarding payments and related accounting reports to investors, collecting escrow deposits for the payment of mortgagor property taxes and insurance, paying taxes and insurance from escrow funds when due and administrating foreclosure actions when necessary. Loan servicing income (a component of noninterest income in the consolidated statements of income) consists of fees earned for servicing mortgage loans sold to third parties, net of amortization expense and impairment losses associated with capitalized mortgage servicing assets.
Loans	(f.) Loans
	Loans are classified as held for investment when management has both the intent and ability to hold the loan for the foreseeable future, or until maturity or payoff. Loans are carried at the principal amount outstanding, net of any unearned income and unamortized deferred fees and costs on originated loans. Loan origination fees and certain direct loan origination costs are deferred, and the net amount is amortized into net interest income over the contractual life of the related loans or over the commitment period as an adjustment of yield. Interest income on loans is based on the principal balance outstanding computed using the effective interest method.
	A loan is considered delinquent when a payment has not been received in accordance with the contractual terms. The accrual of interest income for commercial loans is discontinued when there is a clear indication that the borrower's cash flow may not be sufficient to meet payments as they become due, while the accrual of interest income for retail loans is discontinued when loans reach specific delinquency levels. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments, unless the loan is well secured and in the process of collection. Additionally, if management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management's practice to place such loans on a nonaccrual status immediately, rather than delaying such action until the loans become 90 days past due. When a loan is placed on nonaccrual status, previously accrued and uncollected interest is reversed, amortization of related deferred loan fees or costs is suspended, and income is recorded only to the extent that interest payments are subsequently received in cash and a determination has been made that the principal balance of the loan is collectible. If collectability of the principal is in doubt, payments received are applied to loan principal. A nonaccrual loan may be returned to accrual status when all delinquent principal and interest payments become current in accordance with the terms of the loan agreement, the borrower has demonstrated a period of sustained performance (generally a minimum of six months) and the ultimate collectability of the total contractual principal and interest is no longer in doubt.
	The Company's loan policy dictates the guidelines to be followed in determining when a loan is charged-off. All charge offs are approved by the Bank's senior loan officers or loan committees, depending on the amount of the charge off, and are reported in aggregate to the Bank's Board of Directors. Commercial business and commercial mortgage loans are charged-off when a determination is made that the financial condition of the borrower indicates that the loan will not be collectible in the ordinary course of business. Residential mortgage loans and home equities are generally charged-off or written down when the credit becomes severely delinquent and the balance exceeds the fair value of the property less costs to sell. Indirect and other consumer loans, both secured and unsecured, are generally charged-off in full during the month in which the loan becomes 120 days past due, unless the collateral is in the process of repossession in accordance with the Company's policy.
	A loan is accounted for as a troubled debt restructuring if the Company, for economic or legal reasons related to the borrower's financial condition, grants a significant concession to the borrower that it would not otherwise consider. A troubled debt restructuring may involve the receipt of assets from the debtor in partial or full satisfaction of the loan, or a modification of terms such as a reduction of the stated interest rate or face amount of the loan, a reduction of accrued interest, an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk, or some combination of these concessions. Troubled debt restructurings generally remain on nonaccrual status until there is a sustained period of payment performance (usually six months or longer) and there is a reasonable assurance that the payments will continue. See Allowance for Loan Losses below for further policy discussion and see Note 5 – Loans for additional information.
Off-Balance Sheet Financial Instruments	(g.) Off-Balance Sheet Financial Instruments
	In the ordinary course of business, the Company enters into off-balance sheet financial instruments consisting of commitments to extend credit, standby letters of credit and financial guarantees. Such financial instruments are recorded in the consolidated financial statements when they are funded or when related fees are incurred or received. The Company periodically evaluates the credit risks inherent in these commitments and establishes loss allowances for such risks if and when these are deemed necessary.
	The Company recognizes as liabilities the fair value of the obligations undertaken in issuing the guarantees under the standby letters of credit, net of the related amortization at inception. The fair value approximates the unamortized fees received from the customers for issuing the standby letters of credit. The fees are deferred and recognized on a straight-line basis over the commitment period. Standby letters of credit outstanding at December 31, 2014 had original terms ranging from one to five years.
	Fees received for providing loan commitments and letters of credit that result in loans are typically deferred and amortized to interest income over the life of the related loan, beginning with the initial borrowing. Fees on commitments and letters of credit are amortized to other income as banking fees and commissions over the commitment period when funding is not expected.
Allowance For Loan Losses	(h.) Allowance for Loan Losses
	The allowance for loan losses is established through charges to earnings in the form of a provision for loan losses. When a loan or portion of a loan is determined to be uncollectible, the portion deemed uncollectible is charged against the allowance and subsequent recoveries, if any, are credited to the allowance.
	The allowance for loan losses is evaluated on a regular basis and is based upon periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	The allowance consists of specific and general components. Specific allowances are established for impaired loans. Impaired commercial business and commercial mortgage loans are individually evaluated and measured for impairment based on the present value of expected future cash flows discounted at the loan's effective interest rate, a loan's observable market price, or the fair value of the collateral if the loan is collateral dependent. Regardless of the measurement method, impairment is based on the fair value of the collateral when foreclosure is probable. If the recorded investment in impaired loans exceeds the measure of estimated fair value, a specific allowance is established as a component of the allowance for loan losses. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged-off when deemed uncollectible.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. The Company determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loans obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures unless the loan has been subject to a troubled debt restructure. At December 31, 2014, there were no commitments to lend additional funds to those borrowers whose loans were classified as impaired.
	General allowances are established for loan losses on a portfolio basis for loans that do not meet the definition of impaired. The portfolio is grouped into similar risk characteristics, primarily loan type. The Company applies an estimated loss rate, which considers both look-back and loss emergence periods, to each loan group. The loss rate is based on historical experience, with look-back periods that range from 24 to 48 months depending on the loan type, and as a result can differ from actual losses incurred in the future. The historical loss rate is adjusted by the loss emergence periods that range from 12 to 24 months depending on the loan type and for qualitative factors such as; levels and trends of delinquent and non-accruing loans, trends in volume and terms, effects of changes in lending policy, the experience, ability and depth of management, national and local economic trends and conditions, concentrations of credit risk, interest rates, highly leveraged borrowers, information risk and collateral risk. The qualitative factors are reviewed at least quarterly and adjustments are made as needed.
	While management evaluates currently available information in establishing the allowance for loan losses, future adjustments to the allowance may be necessary if conditions differ substantially from the assumptions used in making the evaluations. In addition, various regulatory agencies, as an integral part of their examination process, periodically review a financial institution's allowance for loan losses. Such agencies may require the financial institution to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.
Other Real Estate Owned	(i.) Other Real Estate Owned
	Other real estate owned consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the lower of fair value of the asset acquired less estimated costs to sell or "cost" (defined as the fair value at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair market value of the assets received, less estimated selling costs, is charged to the allowance for loan losses and any subsequent valuation write-downs are charged to other expense. In connection with the determination of the allowance for loan losses and the valuation of other real estate owned, management obtains appraisals for properties. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of other real estate owned are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by GAAP. The balance of other real estate owned was $194 thousand and $333 thousand at December 31, 2014 and 2013, respectively.
Company Owned Life Insurance	(j.) Company Owned Life Insurance
	The Company holds life insurance policies on certain current and former employees. The Company is the owner and beneficiary of the policies. The cash surrender value of these policies is included as an asset on the consolidated statements of financial condition, and any increase in cash surrender value is recorded as noninterest income on the consolidated statements of income. In the event of the death of an insured individual under these policies, the Company would receive a death benefit which would be recorded as noninterest income.
Premises And Equipment	(k.) Premises and Equipment
	Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. The Company generally amortizes buildings and building improvements over a period of 15 to 39 years and software, furniture and equipment over a period of 3 to 10 years. Leasehold improvements are amortized over the shorter of the lease term or the useful life of the improvements. Premises and equipment are periodically reviewed for impairment or when circumstances present indicators of impairment.
Goodwill And Other Intangible Assets	(l.) Goodwill and Other Intangible Assets
	Goodwill represents the excess of the purchase price over the fair value of net assets acquired in accordance with the purchase method of accounting for business combinations. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. GAAP requires goodwill to be tested for impairment at the Company's reporting unit level on an annual basis, which for the Company is September 30th, and more frequently if events or circumstances indicate that there may be impairment.
	Impairment exists when a reporting unit's carrying value of goodwill exceeds its implied fair value. In testing goodwill for impairment, GAAP permits the Company to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. A reporting unit is defined as any distinct, separately identifiable component of one of our operating segments for which complete, discrete financial information is available and reviewed regularly by the segment's management. If, after assessing the totality of events and circumstances, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing the two-step impairment test would be unnecessary. However, if the Company concludes otherwise, it would then be required to perform the first step (Step 1) of the goodwill impairment test, and continue to the second step (Step 2), if necessary. Step 1 compares the fair value of a reporting unit with its carrying value, including goodwill. If the carrying value of the reporting unit exceeds its fair value, Step 2 of the goodwill impairment test is performed to measure the amount of impairment loss, if any.
	Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. The Company's intangible assets consist of core deposits and other intangible assets (primarily customer relationships). Core deposit intangible assets are amortized on an accelerated basis over their estimated life of approximately nine and a half years. Other intangible assets are amortized on an accelerated basis over their weighted average estimated life of approximately twenty years. Intangible assets with indefinite useful lives are not amortized until their lives are determined to be definite. Intangible assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. See Note 7 - Goodwill and Other Intangible Assets.
Federal Home Loan Bank ("FHLB") And Federal Reserve Bank ("FRB") Stock	(m.) Federal Home Loan Bank ("FHLB") and Federal Reserve Bank ("FRB") Stock
	The non-marketable investments in FHLB and FRB stock are included in other assets in the consolidated statements of financial condition at par value or cost and are periodically reviewed for impairment. The dividends received relative to these investments are included in other noninterest income in the consolidated statements of income.
	As a member of the FHLB system, the Company is required to maintain a specified investment in FHLB of New York ("FHLBNY") stock in proportion to its volume of certain transactions with the FHLB. FHLBNY stock totaled $15.1 million and $15.8 million as of December 31, 2014 and 2013, respectively.
	As a member of the FRB system, the Company is required to maintain a specified investment in FRB stock based on a ratio relative to the Company's capital. FRB stock totaled $3.9 million as of December 31, 2014 and 2013.
Equity Method Investments	(n.) Equity Method Investments
	The Company has investments in limited partnerships, primarily Small Business Investment Companies, and accounts for these investments under the equity method. These investments are included in other assets in the consolidated statements of financial condition and totaled $4.9 million and $4.8 million as of December 31, 2014 and 2013, respectively.
Treasury Stock	(o.) Treasury Stock
	Acquisitions of treasury stock are recorded at cost. The reissuance of shares in treasury is recorded at weighted-average cost.
Employee Benefits	(p.) Employee Benefits
	The Company participates in a non-contributory defined benefit pension plan for certain employees who previously met participation requirements. The Company also provides post-retirement benefits, principally health and dental care, to employees of a previously acquired entity. The Company has closed the pension and post-retirement plans to new participants. The actuarially determined pension benefit is based on years of service and the employee's highest average compensation during five consecutive years of employment. The Company's policy is to at least fund the minimum amount required by the Employment Retirement Income Security Act of 1974. The cost of the pension and post-retirement plans are based on actuarial computations of current and future benefits for employees, and is charged to noninterest expense in the consolidated statements of income.
	The Company recognizes an asset or a liability for a plans' overfunded status or underfunded status, respectively, in the consolidated financial statements and reports changes in the funded status as a component of other comprehensive income, net of applicable taxes, in the year in which changes occur.
Share-Based Compensation Plans	(q.) Share-Based Compensation Plans
	Compensation expense for stock options and restricted stock awards is based on the fair value of the award on the measurement date, which, for the Company, is the date of grant and is recognized ratably over the service period of the award. The fair value of stock options is estimated using the Black-Scholes option-pricing model. The fair value of restricted stock awards is generally the market price of the Company's stock on the date of grant.
	Share-based compensation expense is included in the consolidated statements of income under salaries and employee benefits for awards granted to management and in other noninterest expense for awards granted to directors.
Income Taxes	(r.) Income Taxes
	Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. A valuation allowance is recognized on deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the assets may not be realized. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Comprehensive Income	(s.) Comprehensive Income
	Comprehensive income includes all changes in shareholders' equity during a period, except those resulting from transactions with shareholders. In addition to net income, other components of the Company's comprehensive income include the after tax effect of changes in net unrealized gain / loss on securities available for sale and changes in net actuarial gain / loss on defined benefit post-retirement plans. Comprehensive income is reported in the accompanying consolidated statements of changes in shareholder's equity and consolidated statements of comprehensive income. See Note 13 - Accumulated Other Comprehensive Income (Loss) for additional information.
Earnings Per Common Share	(t.) Earnings Per Common Share
	The Company calculates earnings per common share ("EPS") using the two-class method in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 260, "Earnings Per Share". The two-class method requires the Company to present EPS as if all of the earnings for the period are distributed to common shareholders and any participating securities, regardless of whether any actual dividends or distributions are made. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities. Certain of the restricted shares issued under the Company's share-based compensation plan are entitled to dividends at the same rate as common stock. The Company has determined that these outstanding non-vested stock awards qualify as participating securities.
	Basic EPS is computed by dividing distributed and undistributed earnings available to common shareholders by the weighted average number of common shares outstanding for the period. Distributed and undistributed earnings available to common shareholders represent net income reduced by preferred stock dividends and distributed and undistributed earnings available to participating securities. Common shares outstanding include common stock and vested restricted stock awards. Diluted EPS reflects the assumed conversion of all potential dilutive securities. A reconciliation of the weighted-average shares used in calculating basic earnings per common share and the weighted average common shares used in calculating diluted earnings per common share for the reported periods is provided in Note 16 - Earnings Per Common Share.
Reclassifications	(u.) Reclassifications
	Certain items in prior financial statements have been reclassified to conform to the current presentation.
Recent Accounting Pronouncements	(v.) Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 is effective for the Company on January 1, 2017. The Company is evaluating the potential impact on the Company's financial statements.
	In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718). The pronouncement was issued to clarify the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. ASU 2014-12 is effective for the Company beginning January 1, 2016, though early adoption is permitted. The adoption of ASU 2014-12 is not expected to have a significant impact on the Company's financial statements.
	In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) –Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for the Company beginning January 1, 2016, though early adoption is permitted. ASU 2015-01 is not expected to have a significant impact on the Company's financial statements.
