Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	(1.) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Financial Institutions, Inc. (individually referred to herein as the "Parent Company" and together with all of its subsidiaries, collectively referred to herein as the "Company") is a financial holding company organized in 1931 under the laws of New York State ("New York"). At December 31, 2017, the Company conducted its business through its three subsidiaries: Five Star Bank (the "Bank"), a New York chartered bank; Scott Danahy Naylon, LLC ("SDN"), a full service insurance agency; and Courier Capital, LLC ("Courier Capital"), an SEC-registered investment advisory and wealth management firm. The Company provides a full range of banking and related financial services to consumer, commercial and municipal customers through its bank and nonbank subsidiaries. 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 and determined there were no material recognizable subsequent events. 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, 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): 2017 2016 2015 Cash payments: Interest expense $ 14,850 $ 11,823 $ 9,323 Income taxes 13,187 10,555 7,494 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans $ 426 $ 496 $ 374 Accrued and declared unpaid dividends 3,859 3,403 3,185 Increase (decrease) in net unsettled security purchases - (170 ) (478 ) Securities transferred from available for sale to held to maturity - - 165,238 Common stock issued for acquisition - 8,100 - Assets acquired and liabilities assumed in business combinations: Loans and other non-cash assets, excluding goodwill and other intangible assets 812 4,848 - Deposits and other liabilities 44 1,845 - (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 costs and fees are deferred at origination 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 six 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 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 typically have original terms ranging from one five (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, 2017, there were no General allowances are established for loan losses on a portfolio basis for loans that are collectively evaluated for impairment. 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 a look-back period of 24 12 28 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 $ 148 107 (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 39 3 10 (l.) Goodwill and Other Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles, and other identifiable intangible assets. 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 twenty Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning net assets and goodwill to each reporting unit. An initial qualitative evaluation (Step 0) is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value (Step 1). If the calculated fair value of the reporting unit exceeds its carrying value, then goodwill is not considered impaired. However, if the carrying value of a reporting unit exceeds its calculated fair value, a goodwill impairment charge is recognized. See Note 7 for additional information on 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 $ 21.9 16.9 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 $ 5.8 4.9 (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 $ 5.7 5.6 (o.) Derivative Instruments and Hedging Activities Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging ("ASC 815"), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity's financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company's objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, none of the Company's derivatives are designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company's assets or liabilities. As such, all changes in fair value of the Company's derivatives are recognized directly in earnings. In accordance with the FASB's fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. (p.) Treasury Stock Acquisitions of treasury stock are recorded at cost. The reissuance of shares in treasury is recorded at weighted-average cost. (q.) Employee Benefits The Company maintains an employer sponsored 401(k) plan where participants may make contributions in the form of salary deferrals and the Company may provide discretionary matching contributions in accordance with the terms of the plan. Contributions due under the terms of our defined contribution plans are accrued as earned by employees. The Company also 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 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. Effective January 1, 2016, the Company's 401(k) plan was amended and the Company's prior matching contribution was discontinued. Concurrent with the 401(k) plan amendment, the Company's defined benefit pension plan was amended to modify the current benefit formula to reflect the discontinuance of the matching contribution in the 401(k) plan, to open the defined benefit pension plan up to eligible employees who were hired on and after January 1, 2007, which provides those new participants with a cash balance benef i t formula . (r.) 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. (s.) 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. (t.) 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 shareholders' equity and consolidated statements of comprehensive income. See Note 14 - Accumulated Other Comprehensive Income (Loss) for additional information. (u.) Earnings Per Common Share The Company calculates earnings per common share ("EPS") using the two-class method in accordance with FASB 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 non-forfeitable dividends are considered 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 17 - Earnings Per Common Share. (v.) Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. (w.) Recent Accounting Pronouncements In May 2014, the FASB 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. The effective date was deferred for one year to the interim and annual periods beginning on or after December 15, 2017. Early adoption is permitted as of the original effective date – interim and annual periods beginning on or after December 15, 2016. The Company's largest source of revenue is net interest income on financial assets and liabilities, which is explicitly excluded from the scope of ASU 2014-09. Revenue streams that are within the scope of ASU 2014-09 include insurance income, investment advisory fees, service charges on deposits and ATM and debit card fees. The adoption of ASU 2014-09, as of January 1, 2018, did not have a significant impact on the Company's financial statements. The Company adopted ASU 2014-09 using the modified retrospective transition method with a cumulative effect adjustment to opening retained earnings as of January 1, 2018. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities . ASU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative-effect adjustment to the

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 Based on management's review and evaluation of the Company's debt securities as of December 31, 2017, the debt securities with unrealized losses were not considered to be OTTI. As of December 31, 2017, 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, 2017, 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.

There was no 481 234 432 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. 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, collateral concessions, forgiveness of principal, forbearance agreements, 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 Outstanding Outstanding Number of Recorded Recorded Contracts Investment Investment 2017 Commercial business 1 $ 3,081 $ 565 Commercial mortgage - - - Total 1 $ 3,081 $ 565 2016 Commercial business 3 $ 526 $ 526 Commercial mortgage 1 550 550 Total 4 $ 1,076 $ 1,076 The loans identified as TDRs by the Company during the years ended December 31, 2017 and 2016 were previously reported as impaired loans prior to restructuring. The modifications during the year ended December 31, 2017 primarily related to collateral concessions. For the year ended December 31, 2016, the restructured loan modifications primarily related to collateral concessions and forbearance. All loans restructured during the years ended December 31, 2017 and 2016 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. There were no loans modified as a TDR during the years ended December 31, 2017 and 2016 that defaulted during the year ended December 31, 2017. For purposes of this disclosure, a loan modified as a TDR is considered to have defaulted when the borrower becomes 90 days past due. 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): Unpaid Average Interest Recorded Principal Related Recorded Income Investment (1) Balance (1) Allowance Investment Recognized 2017 With no related allowance recorded: Commercial business $ 1,635 $ 2,370 $ - $ 853 $ - Commercial mortgage 584 584 - 621 - 2,219 2,954 - 1,474 - With an allowance recorded: Commercial business 3,853 3,853 2,056 4,468 - Commercial mortgage 2,528 2,528 115 1,516 - 6,381 6,381 2,171 5,984 - $ 8,600 $ 9,335 $ 2,171 $ 7,458 $ - 2016 With no related allowance recorded: Commercial business $ 645 $ 1,044 $ - $ 1,032 $ - Commercial mortgage 673 882 - 725 - 1,318 1,926 - 1,757 - With an allowance recorded: Commercial business 1,506 1,506 694 1,141 - Commercial mortgage 352 352 124 486 - 1,858 1,858 818 1,627 - $ 3,176 $ 3,784 $ 818 $ 3,384 $ - (1) Difference between recorded investment and unpaid principal balance represents partial charge-offs. 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): Commercial Commercial Business Mortgage 2017 Uncriticized $ 429,692 $ 791,127 Special mention 7,120 12,185 Substandard 12,951 7,539 Doubtful - - Total $ 449,763 $ 810,851 2016 Uncriticized $ 326,254 $ 652,550 Special mention 10,377 12,690 Substandard 12,448 6,312 Doubtful - - Total $ 349,079 $ 671,552 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.

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, potentially resulting in 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 real estate loans (comprised of conventional mortgages and home equity loans) and residential real estate lines (comprised of 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 [Abstract]
Goodwill And Other Intangible Assets	(7.) GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company performs its annual impairment test of goodwill as of October 1 st of each year. See Note 1 for the Company's accounting policy for goodwill and other intangible assets. The Company completed an evaluation of the contingent earn out liability related to its 2014 acquisition of SDN during the second quarter of 2017, resulting in a contingent consideration liability adjustment of $ 1.2 Under Step 1 of the goodwill impairment review, the fair value of the SDN reporting unit was calculated using income and market-based approaches. Under Step 1, it was determined that the carrying value of our SDN reporting unit exceeded its fair value. Based on this assessment, the Company recorded a goodwill impairment charge related to the SDN reporting unit of $ 1.6 The results of the Company's 2017 annual impairment test indicated no impairment for its Banking segment or its Courier Capital reporting unit; consequently, no goodwill impairment charge for either was recorded in 2017. In addition, the Company's 2017 annual impairment test indicated no additional impairment for the SDN reporting unit. The results of the Company's 2016 annual impairment test indicated no impairment; consequently, no goodwill impairment charge was recorded in 2016. 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 change in the balance for goodwill during the years ended December 31 was as follows (in thousands): Banking Non-Banking Total Balance, January 1, 2016 $ 48,536 $ 11,866 $ 60,402 Acquisition - 6,015 6,015 Balance, December 31, 2016 48,536 17,881 66,417 Impairment - (1,575 ) (1,575 ) Acquisition - 998 998 Balance, December 31, 2017 $ 48,536 $ 17,304 $ 65,840 Other Intangible Assets The Company has other intangible assets that are amortized, consisting of core deposit intangibles and other intangibles.

Derivative Instruments and Hedging Activities [Abstract]
Derivative Instruments and Hedging Activities	(10.) DERIVATIVE INSTRUMENT AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. The Company's existing credit derivatives result from participations in interest rate swaps provided to external lenders as part of loan participation arrangements, therefore, such derivatives are not used to manage interest rate risk in the Company's assets or liabilities. Credit-risk-related Contingent Features The Company has agreements with certain of its derivative counterparties that contain one or more of the following provisions: (a) if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, the Company could also be declared in default on its derivative obligations, and (b) if the Company fails to maintain its status as a well-capitalized institution, the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements.

Commitments And Contingencies [Abstract]
Commitments And Contingencies	(11.) 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): 2017 2016 Commitments to extend credit $ 661,021 $ 555,713 Standby letters of credit 12,181 12,689 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 $ 566 no Lease Obligations The Company is obligated under a number of non-cancellable 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 non-cancellable leases with initial or remaining terms of one year or more, are as follows at December 31, 2017 (in thousands): 2018 $ 2,459 2019 2,370 2020 2,217 2021 2,039 2022 1,775 Thereafter 30,815 $ 41,675 Rent expense relating to these operating leases, included in occupancy and equipment expense in the statements of income, was $ 2.6 2.1 2.0 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	(12.) 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 bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors. The Basel III Capital Rules, a new comprehensive capital framework for U.S. banking organizations, became effective for the Company and the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table that follows) of Common Equity Tier 1 capital ("CET1"), Tier 1 capital and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined). The Company's and the Bank's Common Equity Tier 1 capital includes common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities, and subject to transition provisions. Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For the Company, additional Tier 1 capital at December 31, 2017 includes, subject to limitation, $ 17.3 Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both the Company and the Bank includes a permissible portion of the allowance for loan losses. Tier 2 capital for the Company also includes qualified subordinated debt. At December 31, 2017, the Company's Tier 2 capital included $ 39.1 The Common Equity Tier 1, Tier 1 and Total 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, with certain exclusions, allocated by risk weight category, and certain off-balance-sheet items, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things. When fully phased in on January 1, 2019, the Basel III Capital Rules will require the Company and the Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5 7.0 6.0 8.5 8.0 10.5 4.0 The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625 2.5 The following table presents actual and required capital ratios as of December 31, 2017 and 2016 for the Company and the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31, 2017 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules (in thousands): Minimum Capital Minimum Capital Required to be Required – Basel III Required – Basel III Considered Well Actual Phase-in Schedule Fully Phased-in Capitalized Amount Ratio Amount Ratio Amount Ratio Amount Ratio 2017 Tier 1 leverage: Company $ 322,680 8.13 % $ 158,710 4.00 % $ 158,710 4.00 % $ 198,387 5.00 % Bank 346,532 8.75 158,372 4.00 158,372 4.00 197,965 5.00 CET1 capital: Company 305,351 10.16 172,825 5.75 210,396 7.00 195,368 6.50 Bank 346,532 11.57 172,224 5.75 209,664 7.00 194,688 6.50 Tier 1 capital: Company 322,680 10.74 217,910 7.25 255,481 8.50 240,452 8.00 Bank 346,532 11.57 217,152 7.25 254,592 8.50 239,616 8.00 Total capital: Company 396,483 13.19 278,023 9.25 315,594 10.50 300,565 10.00 Bank 381,204 12.73 277,056 9.25 314,496 10.50 299,520 10.00 2016 Tier 1 leverage: Company $ 265,246 7.36 % $ 144,095 4.00 % $ 144,095 4.00 % $ 180,119 5.00 % Bank 284,765 7.92 143,862 4.00 143,862 4.00 179,828 5.00 CET1 capital: Company 247,906 9.59 132,438 5.13 180,891 7.00 167,970 6.50 Bank 284,765 11.06 132,014 5.13 180,312 7.00 167,432 6.50 Tier 1 capital: Company 265,246 10.26 171,201 6.63 219,654 8.50 206,733 8.00 Bank 284,765 11.06 170,652 6.63 218,950 8.50 206,070 8.00 Total capital: Company 335,241 12.97 222,884 8.63 271,337 10.50 258,416 10.00 Bank 315,699 12.26 222,170 8.63 270,467 10.50 257,588 10.00 As of December 31, 2017, the Company and Bank were considered "well capitalized" under all regulatory capital guidelines. Such determination has been made based on the Tier 1 leverage, CET1capital, Tier 1 capital and total capital ratios. Federal Reserve Requirements The Bank is required to maintain a reserve balance at the FRB of New York. As of December 31, 2017, the Bank was not required to maintain a reserve balance at the FRB of New York. The reserve requirement for the Bank totaled $ 629 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 [Abstract]
Share-Based Compensation	(15.) SHARE-BASED COMPENSATION The Company maintains certain stock-based compensation plans, approved by the Company's shareholders that are administered by the Management Development and Compensation Committee (the "Compensation Committee") of the Board. In May 2015, the Company's shareholders approved the 2015 Long-Term Incentive Plan (the "2015 Plan") to replace the 2009 Management Stock Incentive Plan and the 2009 Directors' Stock Incentive Plan (collectively, the "2009 Plans"). A total of 438,076 313,000 Under the Plan, the Compensation Committee 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 3 5 2 3 Fifty fifty 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 long-term growth 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 12,531 three The grant-date fair value of the TSR performance award granted during the year ended December 31, 2017 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.85 1.45 2.41 21.9 The Company granted 27,831 three 31.88 During the year ended December 31, 2017, the Company granted a total of 8,898 4,454 4,444 one 29.47 7,841 six 30.88 The restricted stock awards granted to the directors and the restricted stock units granted to management in 2017 do not have rights to dividends or dividend equivalents. 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 2017, 2016 or 2015.

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): 2017 2016 2015 Salaries and employee benefits $ 927 $ 601 $ 431 Other noninterest expense 247 244 243 Total share-based compensation expense $ 1,174 $ 845 $ 674

INCOME TAXES The income tax expense for the years ended December 31 consisted of the following (in thousands): 2017 2016 2015 Current tax expense (benefit): Federal $ (3,031 ) $ 13,846 $ 8,720 State 573 82 21 Total current tax expense (2,458 ) 13,928 8,741 Deferred tax expense (benefit): Federal 12,297 (2,175 ) 1,440 State 106 457 358 Total deferred tax expense (benefit) 12,403 (1,718 ) 1,798 Total income tax expense $ 9,945 $ 12,210 $ 10,539 Income tax expense differed from the statutory federal income tax rate for the years ended December 31 as follows: 2017 2016 2015 Statutory federal tax rate 35.0 % 35.0 % 35.0 % Increase (decrease) resulting from: Tax exempt interest income (5.6 ) (5.6 ) (6.1 ) Tax credits and adjustments (6.7 ) 0.3 (0.7 ) Non-taxable earnings on company owned life insurance (1.4 ) (2.2 ) (1.8 ) State taxes, net of federal tax benefit 1.1 0.8 0.7 Nondeductible expenses 0.3 0.2 0.3 Goodwill and contingent consideration adjustments 0.3 (0.9 ) (0.3 ) Other, net (0.1 ) 0.1 - Effective tax rate 22.9 % 27.7 % 27.1 % Total income tax expense (benefit) was as follows for the years ended December 31 (in thousands): 2017 2016 2015 Income tax expense $ 9,945 $ 12,210 $ 10,539 Shareholder's equity 3,909 (1,649 ) (1,456 ) 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 (liability) 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): 2017 2016 Deferred tax assets: Allowance for loan losses $ 8,741 $ 11,938 Deferred compensation 748 1,357 Investment in limited partnerships 599 943 SERP agreements 320 682 Interest on nonaccrual loans 305 453 Share-based compensation 464 604 Net unrealized loss on securities available for sale 1,334 2,326 Other 66 120 Gross deferred tax assets 12,577 18,423 Deferred tax liabilities: REIT dividend 9,412 - Prepaid expenses 720 - Prepaid pension costs 3,255 4,727 Intangible assets 2,594 4,059 Depreciation and amortization 2,023 1,085 Loan servicing assets 250 415 Other 102 234 Gross deferred tax liabilities 18,356 10,520 Net deferred tax asset (liability) $ (5,779 ) $ 7,903 In March 2014, the New York legislature approved changes in the state tax law that was phased-in over two years, beginning in 2015. The primary changes that impacted the Company included 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 repeal of Article 32A and the expanded nexus standards lowered our taxable income apportioned to New York in 2016 and 2015 compared to 2014. In addition, the New York state income tax rate was reduced from 7.1 6.5 On December 22, 2017, the TCJ Act was signed into law which, among other items, reduces the federal statutory corporate tax rate from 35 21 80 Results for the fourth quarter and full year of 2017 were positively impacted by a $ 2.9 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, 2017 or 2016. The Company and its subsidiaries are primarily subject to federal and New York income taxes. The federal income tax years currently open for audits are 2013 through 2017. The New York income tax years currently open for audits are 2013 through 2017. At December 31, 2017, the Company had no federal or New York net operating loss or tax credits carryforwards. The Company's unrecognized tax benefits and changes in unrecognized tax benefits were not significant as of or for the years ended December 31, 2017, 2016 and 2015. There were no no

Employee Benefit Plans	(18.) EMPLOYEE BENEFIT PLANS 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. Until December 31, 2015, the Company matched a participant's contributions up to 4.5 100 3 50 3 no 1.3 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. For employees hired prior to December 31, 2006, who met participation requirements on or before January 1, 2008 ("Tier 1 Participant"), the benefits are generally based on years of service and the employee's highest average compensation during five Effective January 1, 2016, the Plan was amended to open the Plan to eligible employees who were hired on and after January 1, 2007 ("Tier 2 Participant"), and provide these eligible participants with a cash balance benef i t formula . 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): 2017 2016 Change in projected benefit obligation: Projected benefit obligation at beginning of period $ 63,002 $ 59,232 Service cost 3,140 2,885 Interest cost 2,449 2,402 Actuarial (gain) loss 5,016 1,210 Benefits paid and plan expenses (3,171 ) (2,727 ) Projected benefit obligation at end of period 70,436 63,002 Change in plan assets: Fair value of plan assets at beginning of period 75,252 72,358 Actual return on plan assets 11,267 5,621 Employer contributions - - Benefits paid and plan expenses (3,171 ) (2,727 ) Fair value of plan assets at end of period 83,348 75,252 Funded status at end of period $ 12,912 $ 12,250 The accumulated benefit obligation was $ 65.2 58.0 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 has no Estimated benefit payments under the Plan over the next ten years at December 31, 2017 are as follows (in thousands): 2018 $ 2,846 2019 2,885 2020 3,109 2021 3,311 2022 3,528 2023 - 2027 20,500 Net periodic pension cost consists of the following components for the years ended December 31 (in thousands): 2017 2016 2015 Service cost $ 3,140 $ 2,885 $ 2,324 Interest cost on projected benefit obligation 2,449 2,402 2,328 Expected return on plan assets (4,775 ) (4,600 ) (4,820 ) Amortization of unrecognized loss 1,142 938 926 Amortization of unrecognized prior service cost 17 20 20 Net periodic pension cost $ 1,973 $ 1,645 $ 778 The actuarial assumptions used to determine the net periodic pension cost were as follows: 2017 2016 2015 Weighted average discount rate 4.00 % 4.21 % 3.86 % Rate of compensation increase 3.00 % 3.00 % 3.00 % Expected long-term rate of return 6.50 % 6.50 % 6.50 % The actuarial assumptions used to determine the projected benefit obligation were as follows: 2017 2016 2015 Weighted average discount rate 3.49 % 4.00 % 4.21 % Rate of compensation increase 3.00 % 3.00 % 3.00 % 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 long term 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 long term rate of return: 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 long term U.S. Treasury yields to forecast long term inflation. In addition, forecasts by economists and others for long term 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 3 Equity securities Dividend discount model, the smoothed earnings yield model and the equity risk premium model Fixed income securities Current yield to maturity 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 Plan currently prohibits its investment managers from purchasing any security greater than 5 8 Equity securities Short sales Unregistered stocks 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 manager's portfolio. An investment manager's portfolio of commercial MBS and ABS shall not exceed 10 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, 2017 and 2016, the Plan held certain investments which are no longer deemed acceptable to acquire. The Plan continues to allow managers to maintain currently prohibited positions which were not prohibited at the time of purchase. 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. Weighted Average 2017 Percentage of Plan Assets Expected Target at December 31, Long-term Allocation 2017 2016 Rate of Return Asset category: Cash equivalents 0 – 20 6.4 % 6.1 % 0.18 % Equity securities 40 – 60 50.2 47.9 4.02 Fixed income securities 40 – 60 40.2 42.6 2.06 Other financial instruments 0 – 5 3.2 3.4 0.24 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 19 - Fair Value Measurements). 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. ("JPMorgan") and Northern Trust ("NT") to determine the fair value of commingled pension trust funds. The following is a table of the pricing methodology and unobservable inputs used by JPMorgan and NT in pricing commingled pension trust funds ("CPTF"): Principal Valuation Technique(s) Used Unobservable Inputs CPTF - Fixed Income: CPTF (Corporate High Yield) of Market, Comparable Securities EBITDA Multiple JPMorgan CPTF (High Yield) of JPMorgan Market None CPTF (Long Duration Investment Market, NAV, Comparable Securities, None Grade) of JPMorgan Discounted Cash Flow CPTF (Emerging Markets Strategic Market, Comparable Securities None Debt) of JPMorgan (formerly known as JPMorgan Emerging Markets Local Currency Debt) CPTF (Emerging Markets - Fixed Market, Comparable Securities None Income) of JPMorgan NT Collective Aggregate Bond Index NAV None Fund - Lending CPTF – Other: CPTF (Strategic Property) of JPMorgan Market, Income Approach, Debt Credit Spreads, Discount Rate, Loan to Service and Sales Comparison Value Ratio, Terminal Capitalization Rate and Value per Square Foot When valuing Commingled Pension Trust Funds (Equity) JPMorgan uses a market methodology and does not rely on unobservable inputs in those valuations.

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 $ 151 149 The components of accumulated other comprehensive loss related to the defined benefit plan and postretirement benefit plan as of December 31 are summarized below (in thousands): 2017 2016 Defined benefit plan: Net actuarial loss $ (14,348 ) $ (16,966 ) Prior service credit (cost) 5 (12 ) (14,343 ) (16,978 ) Postretirement benefit plan: Net actuarial loss (190 ) (198 ) Prior service credit 169 237 (21 ) 39 Total (14,364 ) (16,939 ) Deferred tax benefit 5,723 6,717 Amounts included in accumulated other comprehensive loss $ (8,641 ) $ (10,222 ) Changes in plan assets and benefit obligations recognized in other comprehensive income on a pre-tax basis during the years ended December 31 are as follows (in thousands): 2017 2016 Defined benefit plan: Net actuarial gain (loss) $ 1,475 $ (189 ) Amortization of net loss 1,142 938 Amortization of prior service cost 17 20 2,634 769 Postretirement benefit plan: Net actuarial loss (15 ) (53 ) Amortization of net loss 24 17 Amortization of prior service credit (68 ) (67 ) (59 ) (103 ) Total recognized in other comprehensive income $ 2,575 $ 666 For the year ending December 31, 2018, the estimated net loss and prior service credit for the plan that will be amortized from accumulated other comprehensive income into net periodic benefit cost is $ 750 72 Supplemental Executive Retirement Agreements The Company has non-qualified Supplemental Executive Retirement Agreements ("SERPs") covering five former executives.

Fair Value Measurements [Abstract]
Fair Value Measurements	(19.) 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. Derivative instruments – credit contracts: The fair value of derivative instruments – credit contracts is determined using quoted secondary market prices for similar financial instruments and are classified as Level 2 in the fair value hierarchy. 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): Quoted Prices in Active Markets for Significant Identical Other Significant Assets or Observable Unobservable Liabilities Inputs Inputs (Level 1) (Level 2) (Level 3) Total 2017 Measured on a recurring basis: Securities available for sale: U.S. Government agencies and government sponsored enterprises $ - $ 161,889 $ - $ 161,889 Mortgage-backed securities - 363,084 - 363,084 Asset-backed securities - - - - $ - $ 524,973 $ - $ 524,973 Other liabilities: Derivative instruments – credit contracts $ - $ 4 $ - $ 4 $ - $ 4 $ - $ 4 Measured on a nonrecurring basis: Loans: Loans held for sale $ - $ 2,718 $ - $ 2,718 Collateral dependent impaired loans - - 3,847 3,847 Other assets: Loan servicing rights - - 990 990 Other real estate owned - - 148 148 $ - $ 2,718 $ 4,985 $ 7,703 2016 Measured on a recurring basis: Securities available for sale: U.S. Government agencies and government sponsored enterprises $ - $ 186,268 $ - $ 186,268 Mortgage-backed securities - 353,467 - 353,467 Asset-backed securities - 191 - 191 $ - $ 539,926 $ - $ 539,926 Other liabilities: Derivative instruments – credit contracts $ - $ - $ - $ - $ - $ - $ - $ - Measured on a nonrecurring basis: Loans: Loans held for sale $ - $ 1,050 $ - $ 1,050 Collateral dependent impaired loans - - 901 901 Other assets: Loan servicing rights - - 1,075 1,075 Other real estate owned - - 107 107 $ - $ 1,050 $ 2,083 $ 3,133 There were no 1 2 December 31, 2017 no The following table presents additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis for which the Company has utilized Level 3 inputs to determine fair value (dollars in thousands).

Changes in Level 3 Fair Value Measurements There were no 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. Long-term borrowings: Long-term borrowings consist of $ 40 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): Level in 2017 2016 Fair Value Estimated Estimated Measurement Carrying Fair Carrying Fair Hierarchy Amount Value Amount Value Financial assets: Cash and cash equivalents Level 1 $ 99,195 $ 99,195 $ 71,277 $ 71,277 Securities available for sale Level 2 524,973 524,973 539,926 539,926 Securities held to maturity Level 2 516,466 512,983 543,338 539,991 Loans held for sale Level 2 2,718 2,718 1,050 1,050 Loans Level 2 2,696,498 2,660,936 2,308,326 2,285,146 Loans (1) Level 3 3,847 3,847 901 901 Accrued interest receivable Level 1 10,776 10,776 9,192 9,192 FHLB and FRB stock Level 2 27,730 27,730 21,780 21,780 Financial liabilities: Non-maturity deposits Level 1 2,358,018 2,358,018 2,292,706 2,292,706 Time deposits Level 2 852,156 848,055 702,516 701,097 Short-term borrowings Level 1 446,200 446,200 331,500 331,500 Long-term borrowings Level 2 39,131 41,485 39,061 40,701 Accrued interest payable Level 1 8,038 8,038 5,394 5,394 Derivative instruments – credit contracts Level 2 4 4 - - (1) Comprised of collateral dependent impaired loans.

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, 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. Supplemental cash flow information is summarized as follows for the years ended December 31 (in thousands): 2017 2016 2015 Cash payments: Interest expense $ 14,850 $ 11,823 $ 9,323 Income taxes 13,187 10,555 7,494 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans $ 426 $ 496 $ 374 Accrued and declared unpaid dividends 3,859 3,403 3,185 Increase (decrease) in net unsettled security purchases - (170 ) (478 ) Securities transferred from available for sale to held to maturity - - 165,238 Common stock issued for acquisition - 8,100 - Assets acquired and liabilities assumed in business combinations: Loans and other non-cash assets, excluding goodwill and other intangible assets 812 4,848 - Deposits and other liabilities 44 1,845 -
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 costs and fees are deferred at origination 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 six 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 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 typically have original terms ranging from one five
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, 2017, there were no General allowances are established for loan losses on a portfolio basis for loans that are collectively evaluated for impairment. 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 a look-back period of 24 12 28 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 $ 148 107
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 39 3 10
Goodwill And Other Intangible Assets	(l.) Goodwill and Other Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles, and other identifiable intangible assets. 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 twenty Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning net assets and goodwill to each reporting unit. An initial qualitative evaluation (Step 0) is made to assess the likelihood of impairment and determine whether further quantitative testing to calculate the fair value is necessary. When the qualitative evaluation indicates that impairment is more likely than not, quantitative testing is required whereby the fair value of each reporting unit is calculated and compared to the recorded book value (Step 1). If the calculated fair value of the reporting unit exceeds its carrying value, then goodwill is not considered impaired. However, if the carrying value of a reporting unit exceeds its calculated fair value, a goodwill impairment charge is recognized. See Note 7 for additional information on 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 $ 21.9 16.9 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 $ 5.8 4.9
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 $ 5.7 5.6
Derivative Instruments And Hedging Activities	(o.) Derivative Instruments and Hedging Activities Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging ("ASC 815"), provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity's financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company's objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, none of the Company's derivatives are designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company's assets or liabilities. As such, all changes in fair value of the Company's derivatives are recognized directly in earnings. In accordance with the FASB's fair value measurement guidance, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Treasury Stock	(p.) Treasury Stock Acquisitions of treasury stock are recorded at cost. The reissuance of shares in treasury is recorded at weighted-average cost.
Employee Benefits	(q.) Employee Benefits The Company maintains an employer sponsored 401(k) plan where participants may make contributions in the form of salary deferrals and the Company may provide discretionary matching contributions in accordance with the terms of the plan. Contributions due under the terms of our defined contribution plans are accrued as earned by employees. The Company also 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 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. Effective January 1, 2016, the Company's 401(k) plan was amended and the Company's prior matching contribution was discontinued. Concurrent with the 401(k) plan amendment, the Company's defined benefit pension plan was amended to modify the current benefit formula to reflect the discontinuance of the matching contribution in the 401(k) plan, to open the defined benefit pension plan up to eligible employees who were hired on and after January 1, 2007, which provides those new participants with a cash balance benef i t formula .
Share-Based Compensation Plans	(r.) 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	(s.) 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	(t.) 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 shareholders' equity and consolidated statements of comprehensive income. See Note 14 - Accumulated Other Comprehensive Income (Loss) for additional information.
Earnings Per Common Share	(u.) Earnings Per Common Share The Company calculates earnings per common share ("EPS") using the two-class method in accordance with FASB 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 non-forfeitable dividends are considered 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 17 - Earnings Per Common Share.
Reclassifications	(v.) Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation.
Recent Accounting Pronouncements	(w.) Recent Accounting Pronouncements In May 2014, the FASB 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. The effective date was deferred for one year to the interim and annual periods beginning on or after December 15, 2017. Early adoption is permitted as of the original effective date – interim and annual periods beginning on or after December 15, 2016. The Company's largest source of revenue is net interest income on financial assets and liabilities, which is explicitly excluded from the scope of ASU 2014-09. Revenue streams that are within the scope of ASU 2014-09 include insurance income, investment advisory fees, service charges on deposits and ATM and debit card fees. The adoption of ASU 2014-09, as of January 1, 2018, did not have a significant impact on the Company's financial statements. The Company adopted ASU 2014-09 using the modified retrospective transition method with a cumulative effect adjustment to opening retained earnings as of January 1, 2018. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities . ASU 2016-01 is intended to improve the recognition and measurement of financial instruments by requiring equity investments to be measured at fair value with changes in fair value recognized in net income; requiring entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement for entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured and amortized at cost on the balance sheet; and requiring an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2017. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. The adoption of ASU 2016-01 is not expected to have a significant impact on the Company's financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . ASU 2016-02 establishes a right of use model that requires a lessee to record a right of use asset and a lease liability for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. A lease will be treated as a sale if it transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing. If the lessor doesn't convey risks and rewards or control, an operating lease results. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years for public business entities. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, with certain practical expedients available. Early adoption is permitted. The Company is assessing the impact of ASU 2016-02 on its financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting . ASU 2016-09 requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also allows an employer to repurchase more of an employee's shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election for forfeitures as they occur. The guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those years. Early adoption was permitted. The adoption of ASU 2016-09 did not have a significant impact on the Company's financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments . ASU 2016-13 amends guidance on reporting credit losses for financial assets held at amortized cost basis and available for sale debt securities. Topic 326 eliminates the probable initial recognition threshold in current GAAP and instead, requires an entity to reflect its current estimate of all expected credit losses based on historical experience, current conditions and reasonable and supportable forecasts. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net amount expected to be collected. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted beginning after December 15, 2018. The Company is assessing the impact of ASU 2016-13 on its financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 provides guidance on the following eight specific cash flow issues: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption was permitted, including adoption in an interim period. As this guidance only affects the classification within the statement of cash flows, this ASU is not expected to have a significant impact on the Company's financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment . ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the new guidance, an entity will recognize an impairment charge for the amount by which the carrying value exceeds the fair value. This standard is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted ASU 2017-04 during the quarter ended June 30, 2017, in connection with the interim goodwill impairment test that was performed. For additional details, see Note 6, Goodwill and Other Intangible Assets. The early adoption of ASU 2017-04 did not have a significant impact on the Company's financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , which provides additional guidance on the presentation of net periodic pension and postretirement benefit costs in the income statement and on the components eligible for capitalization. The amendments in this ASU require that an employer report the service cost component of the net periodic benefit costs in the same income statement line item as other compensation costs arising from services rendered by employees during the period. The non-service-cost components of net periodic benefit costs are to be presented in the income statement separately from the service cost components and outside a subtotal of income from operations. The ASU also allows for the capitalization of the service cost components, when applicable (i.e., as a cost of internally manufactured inventory or a self-constructed asset). The amendments are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods; early adoption was permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in this ASU are to be applied retrospectively. The Company is assessing the impact of ASU 2017-07 on its financial statements. In March 2017, the FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) –Premium Amortization on Purchased Callable Debt Securities . These amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The Company is assessing the impact of ASU 2017-08 on its financial statements. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities . These amendments: (a) expand and refine hedge accounting for both financial and non-financial risk components, (b) align the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and (c) include certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The guidance is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The amendments related to cash flow and net investment hedges existing at the date of adoption should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to presentation and disclosure should be applied prospectively. The Company is assessing the impact of ASU 2017-12 on its financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220) –Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . ASU 2018-02 permits a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the TCJ Act. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The amendments should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the federal corporate income tax rate in the TCJ Act is recognized. The Company is assessing the impact of ASU 2018-02 on its financial statements.
