Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis Of Presentation Tompkins Financial Corporation (“Tompkins” or “the Company”) is a registered Financial Holding Company with the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, organized under the laws of New York State, and is the parent company of Tompkins Trust Company (the “Trust Company”), The Bank of Castile, Mahopac Bank, VIST Bank, and Tompkins Insurance Agencies, Inc. (“Tompkins Insurance”). The Trust Company provides a full array of trust and investment services under the Tompkins Financial Advisors brand. Unless the context otherwise requires, the term “Company” refers to Tompkins Financial Corporation and its subsidiaries. The consolidated financial information included herein combines the results of operations, the assets, liabilities, and shareholders’ equity (including comprehensive income or loss) of the Company and all entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions are eliminated in consolidation. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under U.S. accounting principles generally accepted. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (VIEs) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company’s wholly owned subsidiaries, Sleepy Hollow Capital Trust I, Leesport Capital Trust II, and Madison Statutory Trust I are VIE’s for which the Company is not the primary beneficiary. Accordingly, the accounts of these entities are not included in the Company’s consolidated financial statements. The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclose contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the allowance for loan and lease losses, valuation of goodwill and intangible assets, deferred income tax assets, other-than-temporary impairment on investments, and obligations related to employee benefits. Amounts in the prior years’ consolidated financial statements are reclassified when necessary to conform to the current year’s presentation. The consolidated financial information included herein combines the results of operations, the assets, liabilities, and shareholders’ equity of the Company and its subsidiaries. Amounts in the prior periods’ unaudited condensed consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure and determined that no further disclosures were required. Cash and Cash Equivalents Cash and cash equivalents in the Consolidated Statements of Cash Flows include cash and noninterest bearing balances due from banks, interest-bearing balances due from banks, Federal funds sold, and money market funds. Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that the Company is not exposed to any significant credit risk on cash and cash equivalents. Each bank subsidiary is required to maintain reserve balances by the Federal Reserve Bank of New York. At December 31, 2018, and December 31, 2017, the reserve requirements for the Company’s banking subsidiaries totaled $6.6 million and $6.6 million, respectively. Securities Management determines the appropriate classification of debt and equity securities at the time of purchase. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Debt securities not classified as held-to-maturity and marketable equity securities are classified as either available-for-sale or trading. Available-for-sale securities are stated at fair value with the unrealized gains and losses, net of tax, excluded from earnings and reported as a separate component of accumulated comprehensive income or loss, in shareholders’ equity. Trading securities are stated at fair value, with unrealized gains or losses included in earnings. Beginning January 1, 2018, upon adoption of ASU 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. Securities with limited marketability or restricted equity securities, such as Federal Home Loan Bank stock and Federal Reserve Bank stock, are carried at cost, less any impairment, if any. Premiums and discounts are amortized or accreted over the expected life of the related security as an adjustment to yield using the interest method. Dividend and interest income are recognized when earned. Realized gains and losses on the sale of securities are included in net gain (loss) on securities transactions. The cost of securities sold is based on the specific identification method. At least quarterly, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. If impaired, the Company then assesses whether the unrealized loss is other-than-temporary. An unrealized loss on a debt security is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value, discounted at the security’s effective rate, of the expected future cash flows is less than the amortized cost basis of the debt security. As a result, the credit loss component of an other-than-temporary impairment write-down for debt securities is recorded in earnings while the remaining portion of the impairment loss is recognized, net of tax, in other comprehensive income provided that the Company does not intend to sell the underlying debt security and it is more-likely-than not that the Company would not have to sell the debt security prior to recovery of the unrealized loss, which may be to maturity. If the Company intended to sell any securities with an unrealized loss or it is more-likely-than not that the Company would be required to sell the investment securities, before recovery of their amortized cost basis, then the entire unrealized loss would be recorded in earnings. Loans and Leases Loans are reported at their principal outstanding balance, net of deferred loan origination fees and costs, and unearned income. The Company has the ability and intent to hold its loans for the foreseeable future, except for certain residential real estate loans held-for-sale. The Company provides motor vehicle and equipment financing to its customers through direct financing leases. These leases are carried at the aggregate of lease payments receivable, plus estimated residual values, less unearned income. Unearned income on direct financing leases is amortized over the lease terms, resulting in a level rate of return. Residential real estate loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Fair value is determined on the basis of the rates quoted in the secondary market. Net unrealized losses attributable to changes in market interest rates are recognized through a valuation allowance by charges to income. Loans are generally sold on a non-recourse basis with servicing retained. Any gain or loss on the sale of loans is recognized at the time of sale as the difference between the recorded basis in the loan and the net proceeds from the sale. The Company may use commitments at the time loans are originated or identified for sale to mitigate interest rate risk. The commitments to sell loans and the commitments to originate loans held-for-sale at a set interest rate, if originated, are considered derivatives under ASC Topic 815. The impact of the estimated fair value adjustment was not significant to the consolidated financial statements. Interest income on loans is accrued and credited to income based upon the principal amount outstanding. Loan origination fees and costs are deferred and recognized over the life of the loan as an adjustment to yield. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Loans and leases, including impaired loans, are generally classified as nonaccrual if they are past due as to maturity or payment of principal or interest for a period of more than 90 days, unless such loans are well secured and in the process of collection. Loans that are past due less than 90 days may also be classified as nonaccrual if repayment in full of principal or interest is in doubt. Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within an acceptable time period, and there is a sustained period (generally six consecutive months) of repayment performance by the borrower in accordance with the contractual terms of the loan agreement. When interest accrual is discontinued, all unpaid accrued interest is reversed. Payments received on loans on nonaccrual are generally applied to reduce the principal balance of the loan. The Company applies the provisions of ASC Topic 310-10-35, Loan Impairment, to all impaired commercial and commercial real estate loans over $250,000 and to all loans restructured in a troubled debt restructuring. Allowances for loan losses for the remaining loans are recognized in accordance with ASC Topic 450, Contingencies (“ASC Topic 450”). Management considers a loan to be impaired if, based on current information, it is probable that the Company will be unable to collect all scheduled payments of principal or interest when due, according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the effective interest rate of the loan or, as a practical expedient, at the observable market price or the fair value of collateral (less costs to sell) if the loan is collateral dependent. Management excludes large groups of smaller balance homogeneous loans such as residential mortgages, consumer loans, and leases, which are collectively evaluated. Loans are considered modified in a troubled debt restructuring (“TDR”) when, due to a borrower’s financial difficulties, the Company makes a concession(s) to the borrower that it would not otherwise consider. These modifications may include, among others, an extension for the term of the loan, and granting a period when interest-only payments can be made with the principal payments and interest caught up over the remaining term of the loan or at maturity. Generally, a nonaccrual loan that has been modified in a TDR remains on non-accrual status for a period of six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains on nonaccrual status. In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. For commercial and commercial real estate loans, this conclusion is generally based upon a review of the borrower’s financial condition and cash flow, payment history, economic conditions, and the conditions in the various markets in which the collateral, if any, may be liquidated. In general, consumer loans are charged-off in accordance with regulatory guidelines which provide that such loans be charged-off when the Company becomes aware of the loss, such as from a triggering event that may include new information about a borrower’s intent/ability to repay the loan, bankruptcy, fraud or death, among other things, but in no case will the charge-off exceed specified delinquency timeframes. Such delinquency timeframes state that closed-end retail loans (loans with pre-defined maturity dates, such as real estate mortgages, home equity loans and consumer installment loans) that become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off. For residential real estate loans, charge-off decisions are based upon past due status, current assessment of collateral value, and general market conditions in the areas where the properties are located. Acquired Loans and Leases Loans acquired in acquisitions, subsequent to the effective date of ASC Topic 805, Business Combination, are recorded at fair value and subsequently accounted for in accordance with ASC Topic 310, and there is no carryover of the related allowance for loan and lease losses. Loans acquired with evidence of credit impairment are accounted for under ASC Subtopic 310-30. These loans may be aggregated and accounted for as pools of loans if the loans being aggregated have common risk characteristics. In the VIST acquisition, the Company elected to account for the loans with evidence of credit deterioration individually rather than aggregate them into pools. The difference between the undiscounted cash flows expected at acquisition and the investment in the acquired loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment, as a loss accrual or as a valuation allowance. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through an adjustment of the yield on the loans over the remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Valuation allowances (recognized in the allowance for loan losses) on these impaired loans reflect only losses incurred after the acquisition (representing all cash flows that were expected at acquisition but currently are not expected to be received). Acquired loans not exhibiting evidence of credit impairment at the time of acquisition are accounted for under ASC Subtopic 310-20. The Company amortizes/accretes into interest income the premium/discount determined at the date of purchase over the life of the loan on a level yield basis. Subsequent to the acquisition date, the methods used to estimate the appropriate allowance for loan losses are similar to originated loans. These loans are placed on nonaccrual status in accordance with the Company’s policy for originated loans. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, we may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. The Company determined at acquisition that it could reasonably estimate future cash flows on acquired loans that were past due 90 days or more and on which the Company expects to fully collect the carrying value of the loans net of the allowance for acquired loan losses. As such, the Company does not consider these loans to be nonaccrual or nonperforming. Allowance For Loan and Lease Losses The Company has developed a methodology to measure the amount of estimated loan loss exposure inherent in the loan portfolio to assure that an appropriate allowance is maintained. The Company’s methodology is based upon guidance provided in SEC Staff Accounting Bulletin No. 102, Selected Loan Loss Allowance Methodology and Documentation Issues and allowance allocations are calculated in accordance with ASC Topic 310, Receivables and ASC Topic 450, Contingencies. The model is comprised of four major components that management has deemed appropriate in evaluating the appropriateness of the allowance for loan and lease losses. While none of these components, when used independently, is effective in arriving at a reserve level that appropriately measures the risk inherent in the portfolio, management believes that using them collectively, provides reasonable measurement of the loss exposure in the portfolio. The components include: impaired loans; criticized and classified credits; historical loss experience; and qualitative or subjective analysis. For impaired loans, an allowance is recognized if the fair value of the loan is less than the recorded investment in the loan (recorded investment in the loan is the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). A loan’s fair value reflects the present value of expected future cash flows discounted at the loan’s effective interest rate, or if the loan is collateral dependent, the fair value of the collateral, less estimated disposal costs. If the loan is collateral dependent, the principal balance of the loan is charged-off in an amount equal to the impairment measurement. The fair value of collateral dependent loans is derived primarily from collateral appraisals performed by independent third-party appraisers. For loans that are not impaired, but are rated special mention or worse, management evaluates credits based on elevated risk characteristics and assigns reserves based upon analysis of historical loss experience of loans with similar risk characteristics. For loans that are not impaired or reviewed individually, management assigns a reserve based upon historical loss experience over a designated look-back period. Management has evaluated a variety of look-back periods and has determined that an eight year look back period is appropriate to capture a full range of economic cycles. Management has also evaluated a variety of statistical methods in analyzing loss history, including averages, weighted averages and loss emergence periods and has determined that by applying a loss emergence period analysis to historical losses over a full economic cycle has resulted in a reasonable estimate of losses inherent in the loan portfolio. The model also includes an analysis of a variety of subjective factors to support the reserve estimate. These subjective factors may include allowance allocations for risks that may not otherwise be fully recognized in other components of the model. Among the subjective factors that are routinely considered as part of this analysis are: growth trends in the portfolio, changes in management and/or polices related to lending activities, trends in classified or nonaccrual loans, concentrations of credit, local and national economic trends, and industry trends. Periodically, management conducts an analysis to estimate the loss emergence period for various loan categories based on samples of historical charge-offs. Model output by loan category is reviewed to evaluate the reasonableness of the reserve levels in comparison to the estimated loss emergence period applied to historical loss experience. In addition to the components discussed above, management reviews the model output for reasonableness by analyzing the results in comparisons to recent trends in the loan/lease portfolio, through back-testing of results from prior models in comparison to actual loss history, and by comparing our reserves and loss history to industry peer results. The model results are reviewed by management at the Corporate Credit Policy Committee and presented to the Board of Directors. Additionally, on an annual basis, management conducts a validation process of the model. This validation includes reviewing the appropriateness of model calculations, back testing of model results and appropriateness of key assumptions used in the model. In addition, various Federal and State regulatory agencies, as part of their examination process, review the Company’s allowance and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. For acquired credit impaired loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, (“ASC Topic 310-30”), the Company’s allowance for loan and lease losses is estimated based upon our expected cash flows for these loans. To the extent that we experience a deterioration in borrower credit quality resulting in a decrease in our expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on our estimate of future credit losses over the remaining life of the loans. For acquired non-credit impaired loans accounted for under FASB ASC Topic 310-20, Nonrefundable Fees and Other Costs, (“ASC Topic 310-20”), the Company’s allowance for loan and lease losses is maintained through provisions for loan losses based upon an evaluation process that is similar to our evaluation process used for originated loans. This evaluation, which includes a review of loans on which full collectability may not be reasonably assured, considers, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan loss experience, carrying value of the loans, which includes the remaining net purchase discount or premium, and other factors that warrant recognition in determining our allowance for loan losses. Additionally, in June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which replaces the current "incurred loss" model for recognizing credit losses with an "expected loss" model referred to as the Current Expected Credit Loss ("CECL") model. ASU 2016-13 will become effective for the Company for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Under the CECL model, we will be required to present certain financial assets carried at amortized cost at the net amount expected to be collected. Accordingly, the Company’s management anticipates that this significant accounting rule adjustment will materially affect how we determine our allowance for loan and lease losses as well as our accounting for investment securities. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost, less allowances for depreciation. The provision for depreciation for financial reporting purposes is computed generally by the straight-line method at rates sufficient to write-off the cost of such assets over their estimated useful lives. Buildings are amortized over a period of 10-39 years, and furniture, fixtures, and equipment are amortized over a period of 2-20 years. Leasehold improvements are generally depreciated over the lesser of the lease term or the estimated lives of the improvements. Maintenance and repairs are charged to expense as incurred. Gains or losses on disposition are reflected in earnings. Other Real Estate Owned Other real estate owned consists of properties formerly pledged as collateral to loans, which have been acquired by the Company through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Upon transfer of a loan to foreclosure status, an appraisal is generally obtained and any excess of the loan balance over the fair value, less estimated costs to sell, is charged against the allowance for loan/lease losses. Expenses and subsequent adjustments to the fair value are treated as other operating expense. Goodwill Goodwill represents the excess of purchase price over the fair value of assets acquired in a transaction using purchase accounting. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. Goodwill impairment tests are performed on an annual basis or when events or circumstances dictate. The Company tests goodwill annually as of December 31^st. The Company has the option to perform a qualitative assessment of goodwill, which considers company-specific and economic characteristics that might impact its carrying value. If based on this qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative test (Step 1) is performed, which compares the fair value of the reporting unit to the carrying amount of the reporting unit in order to identify potential impairment. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired. However, if the carrying amount of the reporting unit were to exceed its estimated fair value, a second step (Step 2) would be performed that would compare the implied fair value of the reporting unit’s goodwill with the carrying amount of the goodwill for the reporting unit. The implied fair value of goodwill is determined in the same manner as goodwill that is recognized in a business combination. Significant judgment and estimates are involved in estimating the fair value of the assets and liabilities of the reporting units. Other Intangible Assets Other intangible assets include core deposit intangibles, customer related intangibles, covenants not to compete, and mortgage servicing rights. Core deposit intangibles represent a premium paid to acquire a base of stable, low cost deposits in the acquisition of a bank, or a bank branch, using purchase accounting. The amortization period for core deposit intangible ranges from 5 to 10 years, using an accelerated method. The covenants not to compete are amortized on a straight-line basis over 3 to 6 years, while customer related intangibles are amortized on an accelerated basis over a range of 6 to 15 years. The amortization period is monitored to determine if circumstances require such periods to be revised. The Company periodically reviews its intangible assets for changes in circumstances that may indicate the carrying amount of the asset is impaired. The Company tests its intangible assets for impairment on an annual basis or more frequently if conditions indicate that an impairment loss has more likely than not been incurred. Income Taxes 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 expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are reviewed quarterly and reduced by a valuation allowance if, based upon the information available, it is more likely than not that some or all of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Income. Tax Credit Investments The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method. Under that method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. As of December 31, 2018 and 2017, the Company's remaining investment in qualified affordable housing projects, net of amortization totaled $1.0 million and $1.4 million, respectively. Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase (repurchase agreements) are agreements in which the Company transfers the underlying securities to a third-party custodian’s account that explicitly recognizes the Company’s interest in the securities. The agreements are accounted for as secured financing transactions provided the Company maintains effective control over the transferred securities and meets other criteria as specified in FASB ASC Topic 860, Transfers and Servicing (“ASC Topic 860”). The Company’s agreements are accounted for as secured financings; accordingly, the transaction proceeds are reflected as liabilities and the securities underlying the agreements continue to be carried in the Company’s securities portfolio. Treasury Stock The cost of treasury stock is shown on the Consolidated Statements of Condition as a separate component of shareholders’ equity, and is a reduction to total shareholders’ equity. Shares are released from treasury at fair value, identified on an average cost basis. Trust and Investment Services Assets held in fiduciary or agency capacities for customers are not included in the accompanying Consolidated Statements of Condition, since such items are not assets of the Company. Fees associated with providing trust and investment services are included in noninterest income. Earnings Per Share Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year, exclusive of shares represented by the unvested portion of restricted stock and restricted stock units. Diluted earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year plus the dilutive effect of the unvested portion of restricted stock and restricted stock units and stock issuable upon conversion of common stock equivalents (primarily stock options) or certain other contingencies. The Company currently uses authoritative accounting guidance under ASC Topic 260, Earnings Per Share, which provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. The Company issues stock-based compensation awards that included restricted stock awards that contain such rights. Segment Reporting The Company manages its operations through three reportable business segments in accordance with the standards set forth in FASB ASC Topic 280, “Segment Reporting”. The three segments are: (i) banking (“Banking”), (ii) insurance (“Tompkins Insurance Agencies, Inc.”) and (iii) wealth management (“Tompkins Financial Advisors”). The Company’s insurance services and wealth management services are managed separately from the Bank. Additional information on the segments is presented in Note 22- “Segment and Related Information.” Comprehensive Income (Loss) For the Company, comprehensive income (loss) represents net income plus the net change in unrealized gains or losses on securities available-for-sale for the period (net of taxes), and the actuarial gain or loss and amortization of unrealized amounts in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan (net of taxes), and is presented in the Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Changes in Shareholders’ Equity. Accumulated other comprehensive income (loss) represents the net unrealized gains or losses on securities available-for-sale (net of tax) and unrecognized net actuarial gain or loss, unrecognized prior service costs, and unrecognized net initial obligation (net of tax) in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan. Pension and Other Employee Benefits The Company maintains noncontributory defined-benefit and defined contribution plans, which cover substantially all employees of the Company. In addition, the Company also maintains supplemental employee retirement plans for certain executives and a post-retirement life and healthcare plan. These plans are discussed in detail in Note 11 “Employee Benefit Plans”. The Company incurs certain employment-related expenses associated with these plans. In order to measure the expense associated with these plans, various assumptions are made including the discount rate used to value certain liabilities, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. A third-party actuarial firm is used to assist management in measuring the expense and liability associated with the plans. The Company uses a December 31 measurement date for its plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate. The expenses associated with these plans are charged to current operating expenses. The Company recognizes an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in the Company’s consolidated statements of condition, and recognizes changes in the funded status of these plans in comprehensive income, net of applicable taxes, in the year in which the change occurred. Fair Value Measurements The Company accounts for the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”), for financial assets and financial liabilities. ASC Topic 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. See Note 19 “Fair Value Measurements”. In general, fair values of financial instruments are 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 others. Revenue Recognition Tompkins adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) as of January 1, 2018, the impact of which is discussed below. Under ASU 2014-09, the Company adopted new policies related to revenue recognition. In general, for revenue not associated with financial instruments, guarantees and lease contracts, the Company applies the following steps when recognizing revenue from contracts with customers: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when a performance obligation is satisfied. Tompkins' contracts with customers are generally short term in nature, typically due within one year or less or cancellable by the Company or the Company's customer upon a short notice period. Performance obligations for the Company's customer contracts are generally satisfied at a single point in time, typically when the transaction is complete, or over time. For performance obligations satisfied over time, Tompkins primarily uses the output method, directly measuring the value of the products/services transferred to the customer, to determine when performance obligations have been satisfied. The Company typically receives payment from customers and recognizes revenue concurrent with the satisfaction of the Company's performance obligations. In most cases, this occurs within a single financial reporting period. For payments received in advance of the satisfaction of performance obligations, revenue recognition is deferred until such time as the performance obligations have been satisfied. In cases where the Company has not received payment despite satisfaction of the Company's performance obligations, the Company accrues an estimate of the amount due in the period the Company's performance obligations have been satisfied. For contracts with variable components, only amounts for which collection is probable are accrued. The Company generally acts in a principal capacity, on the Company's own behalf, in most of the Company's contracts with customers. In such transactions, Tompkins recognizes revenue and the related costs to provide the services on a gross basis in the Company's financial statements. In some cases, Tompkins acts in an agent capacity, deriving revenue through assisting other entities in transactions with the Company's customers. In such transactions, Tompkins recognizes revenue and the related costs to provide the services on a net basis in the Company's financial statements. These transactions recognized on a net basis primarily relate to insurance and brokerage commissions and fees derived from the Company's customers' use of various interchange and ATM/debit card networks. Accounting Standards Updates In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” ("ASC 606"). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies generally will be required to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method for all contracts. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605, Revenue Recognition. The Company recorded a net increase to beginning retained earnings of $1.8 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The impact on beginning retained earnings was primarily driven by the recognition of $1.8 million of contingency income related to our insurance business segment. The adoption of ASC 606 did not have a significant impact on the Company’s consolidated financial statements as of and for the twelve months ended December 31, 2018 and, as a result, comparisons of revenues and operating profit performance between periods are not significantly affected by the adoption of this ASU. Refer to Note 14 "Revenue Recognition" for additional disclosures required by ASC 606. In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” This ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments by making targeted improvements to GAAP as follows: (1) require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer; (2) simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value; (3) eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (4) eliminate the requirement for public business 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 at amortized cost on the balance sheet; (5) require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (6) require 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; (7) require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (8) clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company adopted ASU No. 2016-01 effective January 1, 2018, and recognized a cumulative-effect adjustment of $65,000 for the after-tax impact of the unrealized loss on equity securities. In addition, the Company measured the fair value of its loan portfolio as of December 31, 2018 using an exit price notion. Refer to Note 19 - "Fair Value". In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. The Company adopted ASU No. 2016-15 on January 1, 2018. ASU No. 2016-15 did not have a material impact on the Company’s consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. ASU 2017-05 reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. The Company adopted ASU No. 2017-05 on January 1, 2018. ASU No. 2017-15 did not have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” Under the new guidance, employers are required to present the service cost component of the net periodic benefit cost in the same income statement line item (e.g., Salaries and Benefits) as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components of net periodic benefit cost separately (e.g., Other Noninterest Expense) from the line item that includes the service cost. ASU No. 2017-07 is effective for interim and annual reporting periods beginning after December 15, 2017. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. The guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. The Company adopted ASU No. 2017-07 on January 1, 2018 and utilized the ASU’s practical expedient allowing entities to estimate amounts for comparative periods using the information previously disclosed in their pension and other postretirement benefit plan footnote. ASU No. 2017-07 did not have a material impact on the Company’s consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718)- Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. ASU 2017-09 became effective for us on January 1, 2018 and did not have a significant impact on our consolidated financial statements. ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 (Tax Cuts and Jobs Act of 2017). ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate of 35 percent and the newly enacted 21 percent corporate income tax rate. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted, including adoption in any interim period, for (i) public business entities for reporting periods for which financial statements have not yet been issued and (ii) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The changes are applied retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act of 2017 is recognized. The Company early adopted ASU 2018-02 in 2017, which resulted in the reclassification from accumulated other comprehensive income (loss) to retained earnings totaling $10.0 million, reflected in the consolidated statements of changes in shareholders' equity. ASU 2018-05, "Income Taxes (Topic 740) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 118." ASU 2018-05 amends the Accounting Standards Codification to incorporate various SEC paragraphs pursuant to the issuance of SAB 118. SAB 118 addresses the application of generally accepted accounting principles in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act of 2017. See Note 15 - "Income Taxes". ASU 2016-02,“Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-2 will be effective for Tompkins on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company occupies certain banking offices and uses certain equipment under noncancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. Tompkins has prepared an inventory of its leases and evaluated the impact of this ASU on these leases. Upon adoption of the guidance, the Company expects to report increased assets and increased liabilities as a result of recognizing right-of-use assets and lease liabilities on its consolidated statement of condition. ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. Tompkins is currently evaluating the requirements of the new guidance to determine what modifications to our existing allowance methodology may be required. The Company has formed a cross-functional committee that is assessing our data and system needs and developing a CECL compliant model while gathering the requisite data. The Company expects that the new guidance will likely result in an increase in the allowance; however, Tompkins is unable to quantify the impact at this time since we are still reviewing the guidance. The extent of any impact to our allowance will depend, in part, upon the composition of our loan portfolio at the adoption date as well as economic conditions and loss forecasts at that date. The guidance of ASU 2016-13 was recently amended by ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses,” which changed the effective date for non-public companies and clarified that operating lease receivables are not within the scope of the standard. ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for us on January 1, 2020, with early adoption permitted for interim or annual impairment tests beginning in 2017. Tompkins is currently evaluating the potential impact of ASU 2017-04 on our consolidated financial statements. ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements. ASU 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements. ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 will be effective for us on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on our consolidated financial statements. ASU 2018-14, “Compensation - Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20).” ASU 2018-14 amends and modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The amendments in this update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. ASU 2018-14 will be effective for us on January 1, 2021, with early adoption permitted, and is not expected to have a significant impact on our consolidated financial statements. ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 clarifies certain aspects of ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract. ASU 2018-15 will be effective for us on January 1, 2020, with early adoption permitted. Tompkins is currently evaluating the potential impact of ASU 2018-15 on our consolidated financial statements. ASU 2018-16, “Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct U.S. Treasury obligations, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. ASU 2018-16 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements.

Summary of Significant Accounting Policies

Basis Of Presentation

Tompkins Financial Corporation (“Tompkins” or “the Company”) is a registered Financial Holding Company with the Federal Reserve Board pursuant to the Bank Holding Company Act of 1956, as amended, organized under the laws of New York State, and is the parent company of Tompkins Trust Company (the “Trust Company”), The Bank of Castile, Mahopac Bank, VIST Bank, and Tompkins Insurance Agencies, Inc. (“Tompkins Insurance”). The Trust Company provides a full array of trust and investment services under the Tompkins Financial Advisors brand. Unless the context otherwise requires, the term “Company” refers to Tompkins Financial Corporation and its subsidiaries.

The consolidated financial information included herein combines the results of operations, the assets, liabilities, and shareholders’ equity (including comprehensive income or loss) of the Company and all entities in which the Company has a controlling financial interest. All significant intercompany balances and transactions are eliminated in consolidation.

The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under U.S. accounting principles generally accepted. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company consolidates voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (VIEs) are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The Company’s wholly owned subsidiaries, Sleepy Hollow Capital Trust I, Leesport Capital Trust II, and Madison Statutory Trust I are VIE’s for which the Company is not the primary beneficiary. Accordingly, the accounts of these entities are not included in the Company’s consolidated financial statements.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclose contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the allowance for loan and lease losses, valuation of goodwill and intangible assets, deferred income tax assets, other-than-temporary impairment on investments, and obligations related to employee benefits. Amounts in the prior years’ consolidated financial statements are reclassified when necessary to conform to the current year’s presentation.

The consolidated financial information included herein combines the results of operations, the assets, liabilities, and shareholders’ equity of the Company and its subsidiaries. Amounts in the prior periods’ unaudited condensed consolidated financial statements are reclassified when necessary to conform to the current periods’ presentation.

The Company has evaluated subsequent events for potential recognition and/or disclosure and determined that no further disclosures were required.

Cash and Cash Equivalents

Cash and cash equivalents in the Consolidated Statements of Cash Flows include cash and noninterest bearing balances due from banks, interest-bearing balances due from banks, Federal funds sold, and money market funds. Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that the Company is not exposed to any significant credit risk on cash and cash equivalents. Each bank subsidiary is required to maintain reserve balances by the Federal Reserve Bank of New York. At December 31, 2018, and December 31, 2017, the reserve requirements for the Company’s banking subsidiaries totaled $6.6 million and $6.6 million, respectively.

Securities

Management determines the appropriate classification of debt and equity securities at the time of purchase. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost. Debt securities not classified as held-to-maturity and marketable equity securities are classified as either available-for-sale or trading. Available-for-sale securities are stated at fair value with the unrealized gains and losses, net of tax, excluded from earnings and reported as a separate component of accumulated comprehensive income or loss, in shareholders’ equity. Trading securities are stated at fair value, with unrealized gains or losses included in earnings.

Beginning January 1, 2018, upon adoption of ASU 2016-01, equity securities with readily determinable fair values are stated at fair value with realized and unrealized gains and losses reported in income. For periods prior to January 1, 2018, equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. Securities with limited marketability or restricted equity securities, such as Federal Home Loan Bank stock and Federal Reserve Bank stock, are carried at cost, less any impairment, if any.

Premiums and discounts are amortized or accreted over the expected life of the related security as an adjustment to yield using the interest method. Dividend and interest income are recognized when earned. Realized gains and losses on the sale of securities are included in net gain (loss) on securities transactions. The cost of securities sold is based on the specific identification method.

At least quarterly, the Company performs an assessment to determine whether there have been any events or economic circumstances indicating that a security with an unrealized loss has suffered other-than-temporary impairment. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. If impaired, the Company then assesses whether the unrealized loss is other-than-temporary. An unrealized loss on a debt security is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value, discounted at the security’s effective rate, of the expected future cash flows is less than the amortized cost basis of the debt security. As a result, the credit loss component of an other-than-temporary impairment write-down for debt securities is recorded in earnings while the remaining portion of the impairment loss is recognized, net of tax, in other comprehensive income provided that the Company does not intend to sell the underlying debt security and it is more-likely-than not that the Company would not have to sell the debt security prior to recovery of the unrealized loss, which may be to maturity. If the Company intended to sell any securities with an unrealized loss or it is more-likely-than not that the Company would be required to sell the investment securities, before recovery of their amortized cost basis, then the entire unrealized loss would be recorded in earnings.

Loans and Leases

Loans are reported at their principal outstanding balance, net of deferred loan origination fees and costs, and unearned income. The Company has the ability and intent to hold its loans for the foreseeable future, except for certain residential real estate loans held-for-sale. The Company provides motor vehicle and equipment financing to its customers through direct financing leases. These leases are carried at the aggregate of lease payments receivable, plus estimated residual values, less unearned income. Unearned income on direct financing leases is amortized over the lease terms, resulting in a level rate of return.

Residential real estate loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Fair value is determined on the basis of the rates quoted in the secondary market. Net unrealized losses attributable to changes in market interest rates are recognized through a valuation allowance by charges to income. Loans are generally sold on a non-recourse basis with servicing retained. Any gain or loss on the sale of loans is recognized at the time of sale as the difference between the recorded basis in the loan and the net proceeds from the sale. The Company may use commitments at the time loans are originated or identified for sale to mitigate interest rate risk. The commitments to sell loans and the commitments to originate loans held-for-sale at a set interest rate, if originated, are considered derivatives under ASC Topic 815. The impact of the estimated fair value adjustment was not significant to the consolidated financial statements.

Interest income on loans is accrued and credited to income based upon the principal amount outstanding. Loan origination fees and costs are deferred and recognized over the life of the loan as an adjustment to yield. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments are due. Loans and leases, including impaired loans, are generally classified as nonaccrual if they are past due as to maturity or payment of principal or interest for a period of more than 90 days, unless such loans are well secured and in the process of collection. Loans that are past due less than 90 days may also be classified as nonaccrual if repayment in full of principal or interest is in doubt.

Loans may be returned to accrual status when all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within an acceptable time period, and there is a sustained period (generally six consecutive months) of repayment performance by the borrower in accordance with the contractual terms of the loan agreement. When interest accrual is discontinued, all unpaid accrued interest is reversed. Payments received on loans on nonaccrual are generally applied to reduce the principal balance of the loan.

The Company applies the provisions of ASC Topic 310-10-35, Loan Impairment, to all impaired commercial and commercial real estate loans over $250,000 and to all loans restructured in a troubled debt restructuring. Allowances for loan losses for the remaining loans are recognized in accordance with ASC Topic 450, Contingencies (“ASC Topic 450”). Management considers a loan to be impaired if, based on current information, it is probable that the Company will be unable to collect all scheduled payments of principal or interest when due, according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the effective interest rate of the loan or, as a practical expedient, at the observable market price or the fair value of collateral (less costs to sell) if the loan is collateral dependent. Management excludes large groups of smaller balance homogeneous loans such as residential mortgages, consumer loans, and leases, which are collectively evaluated.

Loans are considered modified in a troubled debt restructuring (“TDR”) when, due to a borrower’s financial difficulties, the Company makes a concession(s) to the borrower that it would not otherwise consider. These modifications may include, among others, an extension for the term of the loan, and granting a period when interest-only payments can be made with the principal payments and interest caught up over the remaining term of the loan or at maturity. Generally, a nonaccrual loan that has been modified in a TDR remains on non-accrual status for a period of six months to demonstrate that the borrower is able to meet the terms of the modified loan. However, performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of loan modification or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains on nonaccrual status.

In general, the principal balance of a loan is charged off in full or in part when management concludes, based on the available facts and circumstances, that collection of principal in full is not probable. For commercial and commercial real estate loans, this conclusion is generally based upon a review of the borrower’s financial condition and cash flow, payment history, economic conditions, and the conditions in the various markets in which the collateral, if any, may be liquidated. In general, consumer loans are charged-off in accordance with regulatory guidelines which provide that such loans be charged-off when the Company becomes aware of the loss, such as from a triggering event that may include new information about a borrower’s intent/ability to repay the loan, bankruptcy, fraud or death, among other things, but in no case will the charge-off exceed specified delinquency timeframes. Such delinquency timeframes state that closed-end retail loans (loans with pre-defined maturity dates, such as real estate mortgages, home equity loans and consumer installment loans) that become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off. For residential real estate loans, charge-off decisions are based upon past due status, current assessment of collateral value, and general market conditions in the areas where the properties are located.

Acquired Loans and Leases

Loans acquired in acquisitions, subsequent to the effective date of ASC Topic 805, Business Combination, are recorded at fair value and subsequently accounted for in accordance with ASC Topic 310, and there is no carryover of the related allowance for loan and lease losses. Loans acquired with evidence of credit impairment are accounted for under ASC Subtopic 310-30. These loans may be aggregated and accounted for as pools of loans if the loans being aggregated have common risk characteristics. In the VIST acquisition, the Company elected to account for the loans with evidence of credit deterioration individually rather than aggregate them into pools. The difference between the undiscounted cash flows expected at acquisition and the investment in the acquired loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment, as a loss accrual or as a valuation allowance.

Increases in expected cash flows subsequent to the acquisition are recognized prospectively through an adjustment of the yield on the loans over the remaining life, while decreases in expected cash flows are recognized as impairment through a loss provision and an increase in the allowance for loan losses. Valuation allowances (recognized in the allowance for loan losses) on these impaired loans reflect only losses incurred after the acquisition (representing all cash flows that were expected at acquisition but currently are not expected to be received).

Acquired loans not exhibiting evidence of credit impairment at the time of acquisition are accounted for under ASC Subtopic 310-20. The Company amortizes/accretes into interest income the premium/discount determined at the date of purchase over the life of the loan on a level yield basis. Subsequent to the acquisition date, the methods used to estimate the appropriate allowance for loan losses are similar to originated loans. These loans are placed on nonaccrual status in accordance with the Company’s policy for originated loans.

Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition may be considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if we can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, we may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable discount. The Company determined at acquisition that it could reasonably estimate future cash flows on acquired loans that were past due 90 days or more and on which the Company expects to fully collect the carrying value of the loans net of the allowance for acquired loan losses. As such, the Company does not consider these loans to be nonaccrual or nonperforming.

Allowance For Loan and Lease Losses

The Company has developed a methodology to measure the amount of estimated loan loss exposure inherent in the loan portfolio to assure that an appropriate allowance is maintained. The Company’s methodology is based upon guidance provided in SEC Staff Accounting Bulletin No. 102, Selected Loan Loss Allowance Methodology and Documentation Issues and allowance allocations are calculated in accordance with ASC Topic 310, Receivables and ASC Topic 450, Contingencies. The model is comprised of four major components that management has deemed appropriate in evaluating the appropriateness of the allowance for loan and lease losses. While none of these components, when used independently, is effective in arriving at a reserve level that appropriately measures the risk inherent in the portfolio, management believes that using them collectively, provides reasonable measurement of the loss exposure in the portfolio. The components include: impaired loans; criticized and classified credits; historical loss experience; and qualitative or subjective analysis. For impaired loans, an allowance is recognized if the fair value of the loan is less than the recorded investment in the loan (recorded investment in the loan is the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). A loan’s fair value reflects the present value of expected future cash flows discounted at the loan’s effective interest rate, or if the loan is collateral dependent, the fair value of the collateral, less estimated disposal costs. If the loan is collateral dependent, the principal balance of the loan is charged-off in an amount equal to the impairment measurement. The fair value of collateral dependent loans is derived primarily from collateral appraisals performed by independent third-party appraisers. For loans that are not impaired, but are rated special mention or worse, management evaluates credits based on elevated risk characteristics and assigns reserves based upon analysis of historical loss experience of loans with similar risk characteristics. For loans that are not impaired or reviewed individually, management assigns a reserve based upon historical loss experience over a designated look-back period. Management has evaluated a variety of look-back periods and has determined that an eight year look back period is appropriate to capture a full range of economic cycles. Management has also evaluated a variety of statistical methods in analyzing loss history, including averages, weighted averages and loss emergence periods and has determined that by applying a loss emergence period analysis to historical losses over a full economic cycle has resulted in a reasonable estimate of losses inherent in the loan portfolio. The model also includes an analysis of a variety of subjective factors to support the reserve estimate. These subjective factors may include allowance allocations for risks that may not otherwise be fully recognized in other components of the model. Among the subjective factors that are routinely considered as part of this analysis are: growth trends in the portfolio, changes in management and/or polices related to lending activities, trends in classified or nonaccrual loans, concentrations of credit, local and national economic trends, and industry trends.

Periodically, management conducts an analysis to estimate the loss emergence period for various loan categories based on samples of historical charge-offs. Model output by loan category is reviewed to evaluate the reasonableness of the reserve levels in comparison to the estimated loss emergence period applied to historical loss experience.

In addition to the components discussed above, management reviews the model output for reasonableness by analyzing the results in comparisons to recent trends in the loan/lease portfolio, through back-testing of results from prior models in comparison to actual loss history, and by comparing our reserves and loss history to industry peer results.

The model results are reviewed by management at the Corporate Credit Policy Committee and presented to the Board of Directors. Additionally, on an annual basis, management conducts a validation process of the model. This validation includes reviewing the appropriateness of model calculations, back testing of model results and appropriateness of key assumptions used in the model. In addition, various Federal and State regulatory agencies, as part of their examination process, review the Company’s allowance and may require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.

For acquired credit impaired loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, (“ASC Topic 310-30”), the Company’s allowance for loan and lease losses is estimated based upon our expected cash flows for these loans. To the extent that we experience a deterioration in borrower credit quality resulting in a decrease in our expected cash flows subsequent to the acquisition of the loans, an allowance for loan losses would be established based on our estimate of future credit losses over the remaining life of the loans.

For acquired non-credit impaired loans accounted for under FASB ASC Topic 310-20, Nonrefundable Fees and Other Costs, (“ASC Topic 310-20”), the Company’s allowance for loan and lease losses is maintained through provisions for loan losses based upon an evaluation process that is similar to our evaluation process used for originated loans. This evaluation, which includes a review of loans on which full collectability may not be reasonably assured, considers, among other matters, the estimated fair value of the underlying collateral, economic conditions, historical net loan loss experience, carrying value of the loans, which includes the remaining net purchase discount or premium, and other factors that warrant recognition in determining our allowance for loan losses.

Additionally, in June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which replaces the current "incurred loss" model for recognizing credit losses with an "expected loss" model referred to as the Current Expected Credit Loss ("CECL") model. ASU 2016-13 will become effective for the Company for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years. Under the CECL model, we will be required to present certain financial assets carried at amortized cost at the net amount expected to be collected. Accordingly, the Company’s management anticipates that this significant accounting rule adjustment will materially affect how we determine our allowance for loan and lease losses as well as our accounting for investment securities.

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost, less allowances for depreciation. The provision for depreciation for financial reporting purposes is computed generally by the straight-line method at rates sufficient to write-off the cost of such assets over their estimated useful lives. Buildings are amortized over a period of 10-39 years, and furniture, fixtures, and equipment are amortized over a period of 2-20 years. Leasehold improvements are generally depreciated over the lesser of the lease term or the estimated lives of the improvements. Maintenance and repairs are charged to expense as incurred. Gains or losses on disposition are reflected in earnings.

Other Real Estate Owned

Other real estate owned consists of properties formerly pledged as collateral to loans, which have been acquired by the Company through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Upon transfer of a loan to foreclosure status, an appraisal is generally obtained and any excess of the loan balance over the fair value, less estimated costs to sell, is charged against the allowance for loan/lease losses. Expenses and subsequent adjustments to the fair value are treated as other operating expense.

Goodwill

Goodwill represents the excess of purchase price over the fair value of assets acquired in a transaction using purchase accounting. Goodwill has an indefinite useful life and is not amortized, but is tested for impairment. Goodwill impairment tests are performed on an annual basis or when events or circumstances dictate. The Company tests goodwill annually as of December 31^st. The Company has the option to perform a qualitative assessment of goodwill, which considers company-specific and economic characteristics that might impact its carrying value. If based on this qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than its carrying amount, then a quantitative test (Step 1) is performed, which compares the fair value of the reporting unit to the carrying amount of the reporting unit in order to identify potential impairment. If the estimated fair value of a reporting unit exceeds its carrying amount, the goodwill of the reporting unit is not considered impaired. However, if the carrying amount of the reporting unit were to exceed its estimated fair value, a second step (Step 2) would be performed that would compare the implied fair value of the reporting unit’s goodwill with the carrying amount of the goodwill for the reporting unit. The implied fair value of goodwill is determined in the same manner as goodwill that is recognized in a business combination. Significant judgment and estimates are involved in estimating the fair value of the assets and liabilities of the reporting units.

Other Intangible Assets

Other intangible assets include core deposit intangibles, customer related intangibles, covenants not to compete, and mortgage servicing rights. Core deposit intangibles represent a premium paid to acquire a base of stable, low cost deposits in the acquisition of a bank, or a bank branch, using purchase accounting. The amortization period for core deposit intangible ranges from 5 to 10 years, using an accelerated method. The covenants not to compete are amortized on a straight-line basis over 3 to 6 years, while customer related intangibles are amortized on an accelerated basis over a range of 6 to 15 years. The amortization period is monitored to determine if circumstances require such periods to be revised. The Company periodically reviews its intangible assets for changes in circumstances that may indicate the carrying amount of the asset is impaired. The Company tests its intangible assets for impairment on an annual basis or more frequently if conditions indicate that an impairment loss has more likely than not been incurred.

Income Taxes

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 expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred taxes are reviewed quarterly and reduced by a valuation allowance if, based upon the information available, it is more likely than not that some or all of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable income and recoverable taxes paid in prior years. Although realization is not assured, management believes it is more likely than not that all of the deferred tax assets will be realized. The Company’s policy is to recognize interest and penalties on unrecognized tax benefits in income tax expense in the Consolidated Statements of Income.

Tax Credit Investments

The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method. Under that method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. As of December 31, 2018 and 2017, the Company's remaining investment in qualified affordable housing projects, net of amortization totaled $1.0 million and $1.4 million, respectively.

Securities Sold Under Agreements to Repurchase

Securities sold under agreements to repurchase (repurchase agreements) are agreements in which the Company transfers the underlying securities to a third-party custodian’s account that explicitly recognizes the Company’s interest in the securities. The agreements are accounted for as secured financing transactions provided the Company maintains effective control over the transferred securities and meets other criteria as specified in FASB ASC Topic 860, Transfers and Servicing (“ASC Topic 860”). The Company’s agreements are accounted for as secured financings; accordingly, the transaction proceeds are reflected as liabilities and the securities underlying the agreements continue to be carried in the Company’s securities portfolio.

Treasury Stock

The cost of treasury stock is shown on the Consolidated Statements of Condition as a separate component of shareholders’ equity, and is a reduction to total shareholders’ equity. Shares are released from treasury at fair value, identified on an average cost basis.

Trust and Investment Services

Assets held in fiduciary or agency capacities for customers are not included in the accompanying Consolidated Statements of Condition, since such items are not assets of the Company. Fees associated with providing trust and investment services are included in noninterest income.

Earnings Per Share

Basic earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year, exclusive of shares represented by the unvested portion of restricted stock and restricted stock units. Diluted earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares outstanding during the year plus the dilutive effect of the unvested portion of restricted stock and restricted stock units and stock issuable upon conversion of common stock equivalents (primarily stock options) or certain other contingencies. The Company currently uses authoritative accounting guidance under ASC Topic 260, Earnings Per Share, which provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. The Company issues stock-based compensation awards that included restricted stock awards that contain such rights.

Segment Reporting

The Company manages its operations through three reportable business segments in accordance with the standards set forth in FASB ASC Topic 280, “Segment Reporting”. The three segments are: (i) banking (“Banking”), (ii) insurance (“Tompkins Insurance Agencies, Inc.”) and (iii) wealth management (“Tompkins Financial Advisors”). The Company’s insurance services and wealth management services are managed separately from the Bank. Additional information on the segments is presented in Note 22- “Segment and Related Information.”

Comprehensive Income (Loss)

For the Company, comprehensive income (loss) represents net income plus the net change in unrealized gains or losses on securities available-for-sale for the period (net of taxes), and the actuarial gain or loss and amortization of unrealized amounts in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan (net of taxes), and is presented in the Consolidated Statements of Comprehensive Income (Loss) and Consolidated Statements of Changes in Shareholders’ Equity. Accumulated other comprehensive income (loss) represents the net unrealized gains or losses on securities available-for-sale (net of tax) and unrecognized net actuarial gain or loss, unrecognized prior service costs, and unrecognized net initial obligation (net of tax) in the Company’s defined-benefit retirement and pension plan, supplemental employee retirement plan, and post-retirement life and healthcare benefit plan.

Pension and Other Employee Benefits

The Company maintains noncontributory defined-benefit and defined contribution plans, which cover substantially all employees of the Company. In addition, the Company also maintains supplemental employee retirement plans for certain executives and a post-retirement life and healthcare plan. These plans are discussed in detail in Note 11 “Employee Benefit Plans”. The Company incurs certain employment-related expenses associated with these plans. In order to measure the expense associated with these plans, various assumptions are made including the discount rate used to value certain liabilities, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. A third-party actuarial firm is used to assist management in measuring the expense and liability associated with the plans. The Company uses a December 31 measurement date for its plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate.

The expenses associated with these plans are charged to current operating expenses. The Company recognizes an asset for a plan’s overfunded status or a liability for a plan’s underfunded status in the Company’s consolidated statements of condition, and recognizes changes in the funded status of these plans in comprehensive income, net of applicable taxes, in the year in which the change occurred.

Fair Value Measurements

The Company accounts for the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC Topic 820”), for financial assets and financial liabilities. ASC Topic 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. See Note 19 “Fair Value Measurements”.

In general, fair values of financial instruments are 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 others.

Revenue Recognition

Tompkins adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) as of January 1, 2018, the impact of which is discussed below. Under ASU 2014-09, the Company adopted new policies related to revenue recognition. In general, for revenue not associated with financial instruments, guarantees and lease contracts, the Company applies the following steps when recognizing revenue from contracts with customers: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when a performance obligation is satisfied. Tompkins' contracts with customers are generally short term in nature, typically due within one year or less or cancellable by the Company or the Company's customer upon a short notice period. Performance obligations for the Company's customer contracts are generally satisfied at a single point in time, typically when the transaction is complete, or over time. For performance obligations satisfied over time, Tompkins primarily uses the output method, directly measuring the value of the products/services transferred to the customer, to determine when performance obligations have been satisfied. The Company typically receives payment from customers and recognizes revenue concurrent with the satisfaction of the Company's performance obligations. In most cases, this occurs within a single financial reporting period. For payments received in advance of the satisfaction of performance obligations, revenue recognition is deferred until such time as the performance obligations have been satisfied. In cases where the Company has not received payment despite satisfaction of the Company's performance obligations, the Company accrues an estimate of the amount due in the period the Company's performance obligations have been satisfied. For contracts with variable components, only amounts for which collection is probable are accrued. The Company generally acts in a principal capacity, on the Company's own behalf, in most of the Company's contracts with customers. In such transactions, Tompkins recognizes revenue and the related costs to provide the services on a gross basis in the Company's financial statements. In some cases, Tompkins acts in an agent capacity, deriving revenue through assisting other entities in transactions with the Company's customers. In such transactions, Tompkins recognizes revenue and the related costs to provide the services on a net basis in the Company's financial statements. These transactions recognized on a net basis primarily relate to insurance and brokerage commissions and fees derived from the Company's customers' use of various interchange and ATM/debit card networks.

Accounting Standards Updates

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” ("ASC 606"). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies generally will be required to use more judgment and make more estimates than under current guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. Since the guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including trust and asset management fees, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions.

On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method for all contracts. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with the Company’s historic accounting under Topic 605, Revenue Recognition. The Company recorded a net increase to beginning retained earnings of $1.8 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The impact on beginning retained earnings was primarily driven by the recognition of $1.8 million of contingency income related to our insurance business segment. The adoption of ASC 606 did not have a significant impact on the Company’s consolidated financial statements as of and for the twelve months ended December 31, 2018 and, as a result, comparisons of revenues and operating profit performance between periods are not significantly affected by the adoption of this ASU. Refer to Note 14 "Revenue Recognition" for additional disclosures required by ASC 606.

In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” This ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments by making targeted improvements to GAAP as follows: (1) require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer; (2) simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value; (3) eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (4) eliminate the requirement for public business 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 at amortized cost on the balance sheet; (5) require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (6) require 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; (7) require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (8) clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company adopted ASU No. 2016-01 effective January 1, 2018, and recognized a cumulative-effect adjustment of $65,000 for the after-tax impact of the unrealized loss on equity securities. In addition, the Company measured the fair value of its loan portfolio as of December 31, 2018 using an exit price notion. Refer to Note 19 - "Fair Value".

In August 2016, the FASB issued ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 provides guidance related to certain cash flow issues in order to reduce the current and potential future diversity in practice. The Company adopted ASU No. 2016-15 on January 1, 2018. ASU No. 2016-15 did not have a material impact on the Company’s consolidated financial statements.

In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets, including partial sales of real estate. Historically, U.S. GAAP contained several different accounting models to evaluate whether the transfer of certain assets qualified for sale treatment. ASU 2017-05 reduces the number of potential accounting models that might apply and clarifies which model does apply in various circumstances. The Company adopted ASU No. 2017-05 on January 1, 2018. ASU No. 2017-15 did not have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” Under the new guidance, employers are required to present the service cost component of the net periodic benefit cost in the same income statement line item (e.g., Salaries and Benefits) as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components of net periodic benefit cost separately (e.g., Other Noninterest Expense) from the line item that includes the service cost. ASU No. 2017-07 is effective for interim and annual reporting periods beginning after December 15, 2017. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. The guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. The Company adopted ASU No. 2017-07 on January 1, 2018 and utilized the ASU’s practical expedient allowing entities to estimate amounts for comparative periods using the information previously disclosed in their pension and other postretirement benefit plan footnote. ASU No. 2017-07 did not have a material impact on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, “Compensation-Stock Compensation (Topic 718)- Scope of Modification Accounting.” ASU 2017-09 clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if all of the following are the same immediately before and after the change: (i) the award's fair value, (ii) the award's vesting conditions and (iii) the award's classification as an equity or liability instrument. ASU 2017-09 became effective for us on January 1, 2018 and did not have a significant impact on our consolidated financial statements.

ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 (Tax Cuts and Jobs Act of 2017). ASU 2018-02 allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate of 35 percent and the newly enacted 21 percent corporate income tax rate. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted, including adoption in any interim period, for (i) public business entities for reporting periods for which financial statements have not yet been issued and (ii) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The changes are applied retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act of 2017 is recognized. The Company early adopted ASU 2018-02 in 2017, which resulted in the reclassification from accumulated other comprehensive income (loss) to retained earnings totaling $10.0 million, reflected in the consolidated statements of changes in shareholders' equity.

ASU 2018-05, "Income Taxes (Topic 740) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (SAB) No. 118." ASU 2018-05 amends the Accounting Standards Codification to incorporate various SEC paragraphs pursuant to the issuance of SAB 118. SAB 118 addresses the application of generally accepted accounting principles in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act of 2017. See Note 15 - "Income Taxes".

ASU 2016-02,“Leases (Topic 842).” ASU 2016-02 will, among other things, require lessees to recognize a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 does not significantly change lease accounting requirements applicable to lessors; however, certain changes were made to align, where necessary, lessor accounting with the lessee accounting model and ASC Topic 606, “Revenue from Contracts with Customers.” ASU 2016-2 will be effective for Tompkins on January 1, 2019 and will require transition using a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company occupies certain banking offices and uses certain equipment under noncancelable operating lease agreements, which currently are not reflected in its consolidated statement of condition. Tompkins has prepared an inventory of its leases and evaluated the impact of this ASU on these leases. Upon adoption of the guidance, the Company expects to report increased assets and increased liabilities as a result of recognizing right-of-use assets and lease liabilities on its consolidated statement of condition.

ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts and requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective on January 1, 2020. Tompkins is currently evaluating the requirements of the new guidance to determine what modifications to our existing allowance methodology may be required. The Company has formed a cross-functional committee that is assessing our data and system needs and developing a CECL compliant model while gathering the requisite data. The Company expects that the new guidance will likely result in an increase in the allowance; however, Tompkins is unable to quantify the impact at this time since we are still reviewing the guidance. The extent of any impact to our allowance will depend, in part, upon the composition of our loan portfolio at the adoption date as well as economic conditions and loss forecasts at that date.

The guidance of ASU 2016-13 was recently amended by ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses,” which changed the effective date for non-public companies and clarified that operating lease receivables are not within the scope of the standard.

ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for us on January 1, 2020, with early adoption permitted for interim or annual impairment tests beginning in 2017. Tompkins is currently evaluating the potential impact of ASU 2017-04 on our consolidated financial statements.

ASU 2017-08 “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium to require such premiums to be amortized to the earliest call date unless applicable guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt securities held at a discount. ASU 2017-08 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” ASU 2017-12 amends the hedge accounting recognition and presentation requirements in ASC 815 to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting. ASU 2017-12 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements.

ASU 2018-13, “Fair Value Measurement (Topic 820) - Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 modifies the disclosure requirements on fair value measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified as relevant. ASU 2018-13 will be effective for us on January 1, 2020, with early adoption permitted, and is not expected to have a significant impact on our consolidated financial statements.

ASU 2018-14, “Compensation - Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20).” ASU 2018-14 amends and modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. The amendments in this update remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. ASU 2018-14 will be effective for us on January 1, 2021, with early adoption permitted, and is not expected to have a significant impact on our consolidated financial statements.

ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 clarifies certain aspects of ASU 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of a hosting arrangement that is a service contract. ASU 2018-15 will be effective for us on January 1, 2020, with early adoption permitted. Tompkins is currently evaluating the potential impact of ASU 2018-15 on our consolidated financial statements.

ASU 2018-16, “Derivatives and Hedging (Topic 815) - Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” The amendments in this update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815 in addition to the interest rates on direct U.S. Treasury obligations, the LIBOR swap rate, the OIS rate based on the Fed Funds Effective Rate and the Securities Industry and Financial Markets Association (SIFMA) Municipal Swap Rate. ASU 2018-16 became effective for us on January 1, 2019 and is not expected to have a significant impact on our consolidated financial statements.
