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. Three of 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. At December 31, 2019 , and December 31, 2018 , the reserve requirements for the Company’s banking subsidiaries totaled $9.5 million and $6.6 million , respectively. The year-over-year increase in the banking subsidiaries' reserves are directly related to the increase in deposits in 2019 compared to 2018. 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. At adoption of ASU 2016-01, the Company recognized a cumulative-effect adjustment of $65,000 for the after-tax impact of the unrealized loss on equity securities. 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 and lease 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. 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, 2019 and 2018 , the Company's remaining investment in qualified affordable housing projects, net of amortization totaled $485,000 and $ 1.0 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) bank

Since the Company had already adopted ASUs 2016-01 and 2017-12, the related amendments were effective as of November 30, 2019. As part of the adoption, the Company reclassified $138.2 million aggregate amortized cost basis of debt securities held-to-maturity to debt securities available-for-sale. The following table summarizes held-to-maturity securities held by the Company at December 31, 2018 : Held-to-Maturity Securities December 31, 2018 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (In thousands) Obligations of U.S. Government sponsored entities $ 131,306 $ 0 $ 1,198 $ 130,108 Obligations of U.S. states and political subdivisions 9,273 20 24 9,269 Total held-to-maturity debt securities $ 140,579 $ 20 $ 1,222 $ 139,377 The following table sets forth information with regard to sales transactions of securities available-for-sale: Year ended December 31, (In thousands) 2019 2018 2017 Proceeds from sales $ 232,598 $ 70,652 $ 64,106 Gross realized gains 1,123 327 19 Gross realized losses (595 ) (767 ) (426 ) Net gains (losses) on sales of available-for-sale securities $ 528 $ (440 ) $ (407 ) The Company's available-for-sale securities portfolio includes callable securities that may be called prior to maturity. In 2019, the Company recognized gains of $88,000 on securities that were called. The Company also recognized gains of $29,000 and $26,000 on equity securities for the twelve months ended December 31, 2019 and 2018, respectively, reflecting the change in fair value.

The total gross unrealized losses, shown in the tables above, were primarily attributable to changes in interest rates and levels of market liquidity, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell the investment securities that are in an unrealized loss position until recovery of unrealized losses (which may be until maturity), and it is not more-likely-than not that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity. Accordingly, as of December 31, 2019 , and December 31, 2018 , management believes the unrealized losses detailed in the tables above are not other-than-temporary. The Company did no t recognize any net credit impairment charge to earnings on investment securities in 2019 or 2018 . The amortized cost and estimated fair value of debt securities by contractual maturity are shown in the following table. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Mortgage-backed securities are shown separately since they are not due at a single maturity date.

Pledged Securities The Company pledges securities as collateral for public deposits and other borrowings, and sells securities under agreements to repurchase. See “Note 8 - Securities Sold Under Agreements to Repurchase and Federal Funds Purchased” for further discussion. Securities carried of $1.0 billion and $1.2 billion , at December 31, 2019 and 2018 , respectively, were either pledged or sold under agreements to repurchase.

There were no significant changes to the Company’s existing lending policies, underwriting standards or loan review procedures during 2019 . The Company’s Board of Directors approves the lending policies at least annually. The Company recognizes that exceptions to policy guidelines may occasionally occur and has established procedures for approving exceptions to these policy guidelines. Management has also implemented reporting systems to monitor loan originations, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans. Residential real estate loans The Company’s policy is to underwrite residential real estate loans in accordance with secondary market guidelines in effect at the time of origination, including loan-to-value (“LTV”) and documentation requirements. LTVs exceeding 80% for fixed rate loans and 85% for adjustable rate loans require private mortgage insurance to reduce the exposure. The Company verifies applicants’ income, obtains credit reports and independent real estate appraisals in the underwriting process to ensure adequate collateral coverage and that loans are extended to individuals with good credit and income sufficient to repay the loan. In limited circumstances, the Company will make exceptions to secondary market underwriting standards to support community reinvestment activities. The Company originates fixed rate and adjustable rate residential mortgage loans, including loans that have characteristics of both, such as a 7/1 adjustable rate mortgage, which has a fixed rate for the first seven years and then adjusts annually thereafter. The majority of residential mortgage loans originated over the last several years have been fixed rate loans due to the low interest rate environment. Adjustable rate residential real estate loans may be underwritten based upon an initial rate which is below the fully indexed rate; however, the initial rate is generally less than 100 basis points below the fully indexed rate. As such, the Company does not believe that this practice creates any significant credit risk. The Company may sell residential real estate loans in the secondary market based on interest rate considerations. These residential real estate loans are generally sold to Federal Home Loan Mortgage Corporation (“FHLMC”) or State of New York Mortgage Agency (“SONYMA”) without recourse in accordance with standard secondary market loan sale agreements. These residential real estate loan sales are subject to customary representations and warranties, including representations and warranties related to gross incompetence and fraud. The Company has not had to repurchase any loans as a result of these general representations and warranties. During 2019 , 2018 , and 2017 , the Company sold residential mortgage loans totaling $16.9 million , $27.7 million , and $4.6 million , respectively, and realized net gains on these sales of $227,000 , $458,000 , and $50,000 , respectively. These residential real estate loans are generally sold without recourse in accordance with standard secondary market loan sale agreements. When residential mortgage loans are sold to FHLMC or SONYMA, the Company typically retains all servicing rights, which provides the Company with a source of fee income. In connection with the sales in 2019 , 2018 , and 2017 , the Company recorded mortgage-servicing assets of $127,000 , $207,000 , and $38,000 , respectively. Amortization of mortgage servicing assets amounted to $117,000 in 2019 , $69,000 in 2018 , and $122,000 in 2017 . At December 31, 2019 and 2018 , the Company serviced residential mortgage loans aggregating $120.3 million and $120.9 million , including loans securitized and held as available-for-sale securities. Mortgage servicing rights, at amortized basis, totaled $815,000 at December 31, 2019 and $805,000 at December 31, 2018 . These mortgage servicing rights were evaluated for impairment at year-end 2019 and 2018 and no impairment was recognized. Loans held for sale, which are included in residential real estate totaled $807,000 and $2.7 million at December 31, 2019 and 2018 , respectively. As members of the FHLB, the Company’s subsidiary banks may use unencumbered mortgage related assets to secure borrowings from the FHLB. At December 31, 2019 and 2018 , the Company had $415.0 million and $425.0 million , respectively, of term advances from the FHLB that were secured by residential mortgage loans. Commercial and industrial loans The Company’s Commercial Loan Policy sets forth guidelines for debt service coverage ratios, LTV’s and documentation standards. Commercial and industrial loans are primarily made based on identified cash flows of the borrower with consideration given to underlying collateral and personal or government guarantees. The Company’s policy establishes debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt. Commercial and industrial loans are generally secured by the assets being financed or other business assets such as accounts receivable or inventory. Many of the loans in the commercial portfolio have variable interest rates tied to Prime Rate, FHLBNY borrowing rates, or U.S. Treasury indices. Commercial real estate The Company’s Commercial Loan Policy sets forth guidelines for debt service coverage ratios, LTV’s and documentation standards. Commercial real estate loans are primarily made based on identified cash flows of the borrower with consideration given to underlying real estate collateral and personal or government guarantees. The Company’s policy establishes a maximum LTV based on the type of property and debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt. Commercial real estate loans may be fixed or variable rate loans with interest rates tied to Prime Rate, FHLBNY borrowing rates, or U.S. Treasury indices. Agriculture loans Agriculturally-related loans include loans to dairy farms, cash and vegetable crop farms and a variety of other livestock and crop producers. Agriculturally-related loans are primarily made based on identified cash flows of the borrower with consideration given to underlying collateral, personal guarantees, and government related guarantees. Agriculturally-related loans are generally secured by the assets or property being financed or other business assets such as accounts receivable, livestock, equipment, or commodities/crops. The Company’s Commercial Loan Policy establishes a maximum LTV of 75% for real estate secured loans and debt service coverage ratio limits that require a borrower’s cash flow to be sufficient to cover principal and interest payments on all new and existing debt, with limited adjustments to consider commodity market cycles. The policy also establishes maximum LTV ratios for non-real estate collateral, such as livestock, commodities/crops, equipment and accounts receivable. Agriculturally-related loans may be fixed or variable rate with interest tied to Prime Rate, FHLBNY borrowing rates, or U.S. Treasury indices. Consumer and other loans The consumer loan portfolio includes personal installment loans, direct and indirect automobile financing, and overdraft lines of credit. The majority of the consumer portfolio consists of indirect and direct automobile loans. Consumer loans are generally short-term and have fixed rates of interest that are set giving consideration to current market interest rates, the financial strength of the borrower, and internal profitability targets. The Company's Consumer Loan Underwriting Guidelines Policy establishes maximum debt to income ratios and includes guidelines for verification of applicants’ income and receipt of credit reports. Leases Leases are primarily made to commercial customers and the origination criteria typically includes the value of the underlying assets being financed, the useful life of the assets being financed, and identified cash flows of the borrower. Most leases carry a fixed rate of interest that is set giving consideration to current market interest rates, the financial strength of the borrower, and internal profitability targets. Loan and Lease Customers The Company’s loan and lease customers are located primarily in the upstate New York communities served by its three subsidiary banks and in the Pennsylvania communities served by VIST Bank. The Trust Company operates fourteen banking offices in the counties of Tompkins, Cayuga, Cortland, Onondaga and Schuyler, New York. The Bank of Castile operates sixteen banking offices in the counties of Wyoming, Livingston, Genesee, Orleans and Monroe, New York. Mahopac Bank operates fourteen banking offices in the counties of Putnam County, Dutchess County and Westchester, New York. VIST Bank operates twenty offices in the counties of Berks, Montgomery, Philadelphia, Delaware and Schuylkill, Pennsylvania. Other than general economic risks, management is not aware of any material concentrations of credit risk to any industry or individual borrower. Loans to Related Parties Directors and officers of the Company and its affiliated companies were customer of, and had other transactions with, the Company's banking subsidiaries in the ordinary course of business. Such loans and commitments were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company, and did not involve more than normal risk of collectability or present other unfavorable features. Loan transactions with related parties are summarized as follows: (In thousands) December 31, 2019 December 31, 2018 Balance at beginning of year $ 39,595 $ 14,503 New Directors/Executive Officers 0 467 New loans and advancements 19,393 30,570 Loan payments (10,599 ) (5,945 ) Balance at end of year $ 48,389 $ 39,595 Nonaccrual Loans and Leases 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 are placed on nonaccrual status either due to the delinquency status of principal and/or interest (generally when past due 90 or more days) or a judgment by management that the full repayment of principal and interest is unlikely. 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. Loans are generally returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. When management determines that the collection of principal in full is improbable, management will charge-off a partial amount or full amount of the loan balance. Management considers specific facts and circumstances relative to each individual credit in making such a determination. For residential and consumer loans, management uses specific regulatory guidance and thresholds for determining charge-offs. 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 has determined that it can reasonably estimate future cash flows on our current portfolio of acquired loans that are past due 90 days or more and on which the Company is accruing interest and expect to fully collect the carrying value of the loans net of the allowance for acquired loan losses.

Receivables [Abstract]
Allowance for Loan and Lease Losses	Allowance for Loan and Lease Losses Originated Loans and Leases Management reviews the appropriateness of the allowance for loan and lease losses (“allowance”) on a regular basis. Management considers the accounting policy relating to the allowance to be a critical accounting policy, given the inherent uncertainty in evaluating the levels of the allowance required to cover credit losses in the portfolio and the material effect that assumptions could have on the Company’s results of operations. 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 four components include: impaired loans; criticized and classified credits; historical loss experience; and qualitative or subjective analysis. Since the methodology is based upon historical experience and trends as well as management’s judgment, factors may arise that result in different estimations. Significant factors that could give rise to changes in these estimates may include, but are not limited to, changes in economic conditions in the local area, concentration of risk, changes in interest rates, and declines in local property values. While management’s evaluation of the allowance as of December 31, 2019 , considers the allowance to be appropriate, under different conditions or assumptions, the Company may need to adjust the allowance. Acquired Loans and Leases As part of our determination of the fair value of our acquired loans at the time of acquisition, the Company established a credit mark to provide for future losses in our acquired loan portfolio. To the extent that credit quality deteriorates subsequent to acquisition, such deterioration would result in the establishment of an allowance for the acquired loan portfolio. Changes in the allowance for loan and lease losses for the twelve months ended December 31, 2019 , 2018 and 2017 are summarized as follows: (In thousands) 2019 2018 2017 Total allowance at beginning of year $ 43,410 $ 39,771 $ 35,755 Provisions charged to operations 1,366 3,942 4,161 Recoveries on loans and leases 906 2,137 2,429 Charge-offs on loans and leases (5,790 ) (2,440 ) (2,574 ) Total allowance at end of year $ 39,892 $ 43,410 $ 39,771 The following tables detail activity in the allowance for originated and acquired loan and lease losses by portfolio segment for the twelve months ended December 31, 2019 and 2018 .

amounts due according to the contractual terms of the loan agreement. Impaired loans consist of our non-homogenous nonaccrual loans, and all loans restructured in a troubled debt restructuring (TDR). Specific reserves on individually identified impaired loans that are not collateral dependent are measured based on the present value of expected future cash flows discounted at the original effective interest rate of each loan. For loans that are collateral dependent, impairment is measured based on the fair value of the collateral less estimated selling costs, and such impaired amounts are generally charged off. The majority of impaired loans are collateral dependent impaired loans that have limited exposure or require limited specific reserves because of the amount of collateral support with respect to these loans, and previous charge-offs. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured. In these cases, interest is recognized on a cash basis. There was no interest income recognized on impaired loans and leases for 2019 , 2018 and 2017 .

Trust Preferred Debentures
Trust Preferred Debentures	Trust Preferred Debentures The Company has three unconsolidated subsidiary trusts (“the Trusts”): Sleepy Hollow Capital Trust I, Leesport Capital Trust II, and Madison Statutory Trust I. The latter two were acquired in the acquisition of VIST Financial, while Sleepy Hollow Capital Trust I was acquired in a previous acquisition. The Company owns 100% of the common equity of each Trust. The Trusts were formed for the purpose of issuing Company-obligated mandatorily redeemable capital securities to third-party investors and investing the proceeds from the sale in junior subordinated debt securities (subordinated debt) issued by the Company, which are the sole assets of each Trust. Since third-party investors are the primary beneficiaries, the Trusts are not consolidated in the Company’s financial statements. Distributions on the preferred securities issued by the Trusts are payable quarterly at a rate per annum equal to the interest rate being earned by the Trusts on the debenture held by the Trusts and are recorded as interest expense in the consolidated financial statements. The preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the subordinated debt. The subordinated debt, net of the Company’s investment in the Trusts, qualifies as Tier 1 capital under the Board of Governors of the Federal Reserve System (FRB) guidelines. The Company has entered into agreements which, when taken collectively, fully and unconditionally guarantee the obligations under the preferred securities subject to the terms of each of the guarantees. The following table provides information relating to the Trusts as of December 31, 2019 : Description Issuance Date Par Amount Interest Rate Maturity Date Sleepy Hollow Capital Trust I August 2003 $4.0 million 3-month LIBOR plus 3.05% August 2033 Leesport Capital Trust II September 2002 $10.0 million 3-month LIBOR plus 3.45% September 2032 Madison Statutory Trust I June 2003 $5.0 million 3-month LIBOR plus 3.10% June 2033 Sleepy Hollow Capital Trust I In August 2003 , Sleepy Hollow Capital Trust I issued $4.0 million of floating rate (three-month LIBOR plus 305 basis points) trust preferred securities, which represent beneficial interests in the assets of the trust. The trust preferred securities will mature on August 2033 . Distributions on the trust preferred securities are payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year. Sleepy Hollow Capital Trust I also issued $100,000 of common equity securities to the Company. The proceeds of the offering were used to acquire the Company’s subordinated debentures that are due concurrently with the trust preferred securities. Leesport Capital Trust II Leesport Capital Trust II, a Delaware statutory business trust, was formed on September 26, 2002 and issued $ 10.0 million of mandatory redeemable capital securities carrying a floating interest rate of three month LIBOR plus 3.45% . These debentures are the sole assets of the Trust. The terms of the junior subordinated debentures are the same as the terms of the capital securities. The obligations under the debentures constitute a full and unconditional guarantee by VIST Financial of the obligations of the Trust under the capital securities.

Employee Benefit Plans	12 Months Ended

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company maintains a noncontributory defined-benefit plan (the "DB Pension Plan") and two noncontributory defined-contribution retirement plans (the "DC Retirement Plan" and "2015 DC Retirement Plan") which cover substantially all employees of the Company. The DB Pension Plan was closed to new employees at year-end 2009 and was frozen on July 31, 2015. The benefits under the DB Pension Plan are based on years of service, age and percentages of the employees' average final compensation. Assets of the Company's DB Pension Plan are invested in common and preferred stock, mutual funds and cash equivalents. At December 31, 2019 and 2018 , DB Pension Plan assets included 41,292 and 42,192 shares of Tompkins' common stock that had a fair value of $3.8 million and $3.2 million , respectively. The defined-contribution retirement plans cover substantially all employees of the Company who have reached the age of 21 and completed one year of service. For participants in these plans, the Company makes contributions to an account set up in the participant's name. The amount equals a percentage of pay and varies based on the participant's age, service, and tenure with the Company. The defined-contribution retirement plans offer the participant a wide range of investment alternatives from which to choose. Expenses related to the defined-contribution plans totaled $4.0 million in 2019 , $3.9 million in 2018 , and $4.1 million in 2017 . The Company maintains supplemental employee retirement plans (“SERPs”) for certain executives. In 2016, certain SERPs were amended and restated to reflect changes resulting from the freezing of the DB Pension Plan and the Company entered into additional SERP agreements with certain executives. In 2019, the SERP for the Company's CEO was amended to expand the definition of "Earnings" under the SERP to better align the scope of compensation included in our CEO's retirement benefits with chief executive compensation in a manner that is more consistent with market practice. All benefits provided under the SERPs are unfunded and the Company makes payments to plan participants. The Company also maintains a post-retirement life and healthcare benefit plan (the “Life and Healthcare Plan”), which was amended in 2005. For employees commencing employment after January 1, 2005, the Company does not contribute towards post-retirement healthcare benefits. Retirees and employees who were eligible to retire when the Life and Healthcare Plan was amended were unaffected. Generally, all other employees were eligible for Health Reimbursement Accounts (“HRA”) with an initial balance equal to the amount of the Company’s estimated then current liability. Contributions to the plan are limited to an annual contribution of 4% of the total HRA defined term. Employees, upon retirement, will be able to utilize their HRA for qualified health costs and deductibles. In 2019, the Retiree Life Benefit program was closed to new entrants, and only employees who attained age 50 as of February 1, 2020 will be eligible to earn this benefit. The amounts related to this change are reflected in the below table as amendments in 2019. The Company engages independent, external actuaries to compute the amounts of liabilities and expenses relating to these plans, subject to the assumptions that the Company selects. The benefit obligation for these plans represents the liability of the Company for current and former employees, and is affected primarily by the following: service cost (benefits attributed to employee service during the period); interest cost (interest on the liability due to the passage of time); actuarial gains/losses (experience during the year different from that assumed and changes in plan assumptions); and benefits paid to participants. The following table sets forth the changes in the projected benefit obligation for the DB Pension Plan and SERPs and the accumulated post-retirement benefit obligation for the Life and Healthcare Plan; and the respective plan assets, and the plans’ funded status and amounts recognized in the Company’s Consolidated Statements of Condition at December 31, 2019 and 2018 (the measurement dates of the plans).

The weighted average annual assumed rate of increase in the per capita cost of covered benefits (the health care cost trend rate) was 5.9% beginning in 2019 and is assumed to decrease gradually to 4.5% in 2026 and beyond. A 1% increase in the assumed health care cost trend rate would increase service and interest costs by approximately $594 and increase the Company’s benefit obligation by approximately $20,000 . A 1% decrease in the assumed health care cost trend rate, would decrease service and interest costs by approximately $526 and decrease the Company’s benefit obligation by approximately $18,000 . To develop the expected long-term rate of return on assets assumption for the DB Pension Plan, the Company considered the historical returns and the future expectations for returns for each asset class, as well as target asset allocations of the pension portfolio. Based on this analysis, the Company selected 7.00% as the long-term rate of return on asset assumption. The discount rates used to determine the Company’s DB Pension Plan and other post-retirement benefit obligations as of December 31, 2019 , and December 31, 2018 , were determined by matching estimated benefit cash flows to a yield curve derived from Citigroup’s regular bond yield at December 31, 2019 and December 31, 2018 . Based on the Company’s anticipation of future experience under the DB Pension Plan, the mortality tables used to determine future benefit obligations under the plan were updated as of December 31, 2019 to the PRI-2012 Mortality Tables with Mortality Improvement Scale MP 2019. The Company updated this assumption based on the new improvement table released by The Society of Actuaries in October 2019 . The appropriateness of the assumptions is reviewed annually. Cash Flows Plan assets are amounts that have been segregated and restricted to provide benefits, and include amounts contributed by the Company and amounts earned from investing contributions, less benefits paid. The Company funds the cost of the SERPs and the Life and Healthcare Plan benefits on a pay-as-you-go basis. The benefits as of December 31, 2019 , expected to be paid in each of the next five fiscal years, and in the aggregate for the five fiscal years thereafter were as follows: (In thousands) DB Pension Plans Life and Healthcare Plan SERP Plan 2020 $ 4,125 $ 557 $ 708 2021 4,275 447 700 2022 4,209 436 754 2023 4,386 429 863 2024 4,478 423 846 2025-2029 23,939 2,162 4,949 Total $ 45,412 $ 4,454 $ 8,820 Plan Assets The Company’s DB Pension Plan’s weighted-average asset allocations at December 31, 2019 and 2018 , respectively, by asset category are as follows: 2019 2018 Equity securities 62 % 61 % Debt securities 36 % 38 % Other 2 % 1 % Total Allocation 100 % 100 % It is the policy of the Trustees to invest the Pension Trust Fund (the “Fund”) for total return. The Trustees seek the maximum return consistent with the interests of the participants and beneficiaries and prudent investment management. The management of the Fund’s assets is in compliance with the guidelines established in the Company’s Pension Plan and Trust Investment Policy, which is reviewed and approved annually by the Tompkins Board of Directors, and the Pension Investment Review Committee. The intention is for the Fund to be prudently diversified. The Fund’s investments will be invested among the fixed income, equity and cash equivalent sectors. The pension committee will designate minimum and maximum positions in any of the sectors. In no case shall more than 10% of the Fund assets consist of qualified securities or real estate of the Company. Unless otherwise approved by the Trustees, the following investments are prohibited: – Restricted stock, private placements, short positions, calls, puts, or margin transactions; – Commodities, oil and gas properties, real estate properties, or – Any investment that would constitute a prohibited transaction as described in the Employee Retirement Income Security Act of 1974 (“ERISA”), section 407, 29 U.S.C. 1106. In general, the investment in debt securities is limited to readily marketable debt securities having a Standard & Poor’s rating of “A” or Moody’s rating of “A”, securities of, or guaranteed by the United States Government or its agencies, or obligations of banks or their holding companies that are rated in the three highest ratings assigned by Fitch Investor Service, Inc. In addition, investments in equity securities must be listed on the NYSE or traded on the national Over The Counter market or listed on the NASDAQ. Cash equivalents generally may be United States Treasury obligations, commercial paper having a Standard & Poor’s rating of “A-1” or Moody’s National Credit Officer rating of “P-1”or higher. The major categories of assets in the Company’s DB Pension Plan as of year-end are presented in the following table. Assets are segregated by the level of valuation inputs within the fair value hierarchy established by ASC Topic 820 utilized to measure fair value (see Note 19-Fair Value Measurements).

The pricing service uses a variety of techniques to determine fair value, including market maker bids, quotes and pricing models. Inputs to the model include recent trades, benchmark interest rates, spreads, and actual and projected cash flows. Based on the inputs used by our independent pricing services, the Company identifies the appropriate level within the fair value hierarchy to report these fair values. U.S. Treasury securities, common stocks and mutual funds are considered Level 1 based on quoted prices in active markets. The Company has an Employee Stock Ownership Plan (ESOP) and a 401(k) Investment and Stock Ownership Plan (ISOP) covering substantially all employees of the Company. The ESOP allows for Company contributions in the form of common stock of the Company. Annually, the Tompkins Board of Directors determines a profit-sharing payout to its employees in accordance with a performance-based formula. A percentage of the approved amount is paid in Company common stock into the ESOP. Contributions are limited to a maximum amount as stipulated in the ESOP. The remaining percentage is either paid out in cash or deferred into the ISOP at the direction of the employee. Compensation expense related to the profit-sharing totaled $4.4 million in 2019 , $4.9 million in 2018 , and $5.8 million in 2017 . Under the ISOP, employees may contribute a percentage of their eligible compensation with a Company match of such contributions up to a maximum match of 4% . Participation in the 401(k) Plan is contingent upon certain age and service requirements. The Company’s expense associated with these matching provisions was $2.9 million in 2019 , $2.6 million in 2018 , and $2.5 million in 2017 . Life insurance benefits are provided to certain officers of the Company. In connection with these policies, the Company reflects life insurance assets on its Consolidated Statements of Condition of $83.0 million at December 31, 2019 , and $81.9 million at December 31, 2018 . The insurance is carried at its cash surrender value on the Consolidated Statements of Condition. Increases in the cash surrender value of the insurance are reflected as noninterest income, net of any related mortality expense. The Company provides split dollar life insurance benefits to certain employees. The plan is unfunded and the estimated liability of the plan of $1.6 million and $1.5 million is recorded in other liabilities in the Consolidated Statements of Condition at December 31, 2019 and 2018 , respectively. Compensation expense related to the split dollar life insurance was approximately $49,801 in 2019 and $52,000 in 2018 .

Share-based Payment Arrangement [Abstract]
Stock Plans and Stock Based Compensation	Stock Plans and Stock Based Compensation In 2019, the 2009 Tompkins Financial Corporation Equity Plan (“2009 Equity Plan”) expired and was replaced by the new Tompkins Financial Corporation 2019 Equity Plan (“2019 Equity Plan”). Under the 2019 Equity Plan, the Company may grant stock appreciation rights ("SARs"), shares of restricted stock and restricted units and performance share awards covering up to 1,275,000 shares of the Company's common stock to certain officers, employees, and nonemployee directors. Additionally, restricted stock awards and restricted units and performance share awards will reduce the shares available for grant under the 2019 Equity Plan by 4.25 shares for each share subject to an award, resulting in a total number of full-value share awards that may be issued under the 2019 Plan to 300,000 . Stock options and SARs are granted at an exercise price equal to the stock’s fair value at the date of grant, may not have a term in excess of ten years, and have vesting periods that range between five and seven years from the grant date. Restricted stock awards have vesting periods that range between five and seven years, and restricted units vest in five years from grant date, and have grant date fair values that equal the closing price of the Company’s common stock on grant date. Prior to the adoption of the 2009 Equity Plan, the Company had similar stock option plans, which remain in effect solely with respect to unexercised options issued under these plans. The Company granted 62,360 equity awards to its employees in 2019 , consisting of 49,365 shares of restricted stock, 4,650 performance share awards and 8,345 restricted stock units. The Company granted 65,785 equity awards to its employees in 2018 , consisting of 65,785 shares of restricted stock. The Company granted 59,333 equity awards to its employees in 2017 , consisting of 59,333 shares of restricted stock. The following table presents the activity related to stock options and SARs under all plans for the year ended December 31, 2019 .

As of December 31, 2019 , unrecognized compensation cost related to unvested stock options and SARs totaled $375,000 . The cost is expected to be recognized over a weighted average period of 2.2 years . Net cash proceeds, tax benefits and intrinsic value related to total stock options, SARs, and restricted stock exercised is as follows: (in thousands) 2019 2018 2017 Proceeds from stock option exercises $ (992 ) $ (540 ) $ (641 ) Tax benefits related to stock option exercises 944 680 1,634 Intrinsic value of stock option exercises 2,460 1,447 3,139 The Company uses the Black-Scholes option-valuation model to determine the fair value of incentive stock options and SARs at the date of grant. The valuation model estimates fair value based on the assumptions listed in the table below. The risk-free rate is the interest rate available on zero-coupon U.S. Treasury instruments with a remaining term equal to the expected term of the share option at the time of grant. The expected dividend yield is based on the dividend trends and the market price of the Company’s stock price at grant. Volatility is largely based on historical volatility of the Company’s stock price. The expected term is based upon historical experience of employee exercises and terminations as the vesting term of the grants. The fair values of the grants are expensed over the vesting periods. There were no stock options or SARs granted in 2019 , 2018 and 2017 .

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (ASC 606) and all subsequent ASUs that modified ASC 606. As stated in Note 1 - "Summary of Significant Accounting Policies ," results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. 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 to beginning retained earnings was primarily driven by the recognition of contingency income related to our insurance business segment. Under ASC 606, the Company made any necessary revisions to its policies related to the new revenue recognition guidance. In general, for revenue not associated with financial instruments, guarantees and lease contracts, we apply 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 performance obligation is satisfied. Our contracts with customers are generally short term in nature, typically due within one year or less or cancellable by us or our customer upon a short notice period. Performance obligations for our 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, we primarily use the output method, directly measuring the value of the products/services transferred to the customer, to determine when performance obligations have been satisfied. We typically receive payment from customers and recognize revenue concurrent with the satisfaction of our 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 the performance obligations have been satisfied. In cases where we have not received payment despite satisfaction of our performance obligations, we accrue an estimate of the amount due in the period our performance obligations have been satisfied. For contracts with variable components, only amounts for which collection is probable are accrued. We generally act in a principal capacity, on our own behalf, in most of our contracts with customers. In such transactions, we recognize revenue and the related costs to provide our services on a gross basis in our financial statements. In some cases, we act in an agent capacity, deriving revenue through assisting other entities in transactions with our customers. In such transactions, we recognized revenue and the related costs to provide our services on a net basis in our financial statements. These transactions primarily relate to insurance and brokerage commissions. ASC 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the new guidance. ASC 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. However, the recognition of these revenue streams did not change significantly upon adoption of ASC 606. Insurance Commissions and Fees Fees are earned upon the effective date of bound coverage, as no significant performance obligation remains after coverage is bound. As the Company has historically recognized revenue in this manner, with the noted exception related to installment billing discussed below, the adoption of ASC 606 will not significantly impact the revenue from this source on a quarterly or annual basis. Installment billing - Agency Bill Prior to the adoption of ASC 606, commission revenue on policies billed in installments were recognized on the latter of the policy effective date or the date that the premium was billed to the client. As a result of the adoption of ASC 606, revenue associated with the issuance of policies will be recognized upon the effective date of the associated policy regardless of the billing method, meaning that commission revenues billed on an installment basis will be now recognized earlier than they had been previously. Revenue will be accrued based upon the completion of the performance obligation creating a current asset for the unbilled revenue until such time as an invoice is generated, typically not to exceed twelve months. The Company does not expect the overall impact of these changes to be significant, but it will result in slight variances from quarter to quarter. Contingent commissions Prior to the adoption of ASC 606, revenue that was not fixed and determinable because a contingency exists was not recognized until the contingency was resolved. Under ASC 606, the Company must use its judgment to estimate the amount of consideration that will be received such that a significant reversal of revenue is not probable. Contingent commissions represent a form of variable consideration associated with the same performance obligation, which is the placement of coverage, for which we earn core commissions. In connection with the new standard, contingent commissions will be estimated with an appropriate constraint applied and accrued relative to the recognition of the corresponding core commissions. The resulting effect on the timing of recognition of contingent commissions will more closely follow a similar pattern as our core commissions with true-ups recognized when payments are received or as additional information that affects the estimate becomes available. Refund of commissions The contract with the insurance carrier dictates commissions paid to the Company shall be refunded to the carrier upon cancellation by the policyholder. As a result, the Company has established a liability for the estimated amount of commission for which the Company does not expect to be entitled, and corresponding reduction to the gross commission received or receivable. The refund liability will be updated at the end of each reporting period for changes in circumstances. Trust & Asset Management Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Mutual Fund & Investment Income Mutual fund and investment income consists of other recurring revenue streams such as commissions from sales of mutual funds and other investments, investment advisory fees from the Company’s Strategic Asset Management Services (SAM) wealth management product. Commissions from the sale of mutual funds and other investments are recognized on trade date, which is when the Company has satisfied its performance obligation. The Company also receives periodic service fees (i.e., trailers) from mutual fund companies typically based on a percentage of net asset value. Trailer revenue is recorded over time, usually monthly or quarterly, as net asset value is determined. Investment advisor fees from the wealth management product is earned over time and based on an annual percentage rate of the net asset value. The investment advisor fees are charged to the customer’s account in advance on the first month of the quarter, and the revenue is recognized over the following three-month period. The Company does engage a third party, LPL Financial, LLC (LPL), to satisfy part of this performance obligation, and therefore this income is reported net of any corresponding expenses paid to LPL. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Card Services Income Fees, exchange, and other service charges are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as MasterCard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. The Company’s performance obligation for fees and exchange are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Other Other service charges include revenue from processing wire and ACH transfers, lock box service and safe deposit box rental. Both wire transfer fees and lock box services are charged on per item basis. Wire and ACH transfer fees are charged at the time of transfer and charged directly to the customer account. Lock box customers are billed monthly and payments are received in the following month through a direct charge to customers’ accounts. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of ASC 606, for the years ended December 31, 2019 and 2018 . Year Ended (In thousands) 12/31/2019 12/31/2018 Noninterest Income In-scope of Topic 606: Commissions and Fees $ 28,252 $ 27,272 Installment Billing (35 ) 6 Refund of Commissions 30 (29 ) Contract Liabilities/Deferred Revenue (195 ) (181 ) Contingent Commissions 3,039 2,301 Subtotal Insurance Revenues 31,091 29,369 Trust and Asset Management 11,441 11,848 Mutual Fund & Investment Income 4,993 5,440 Subtotal Investment Service Income 16,434 17,288 Service Charges on Deposit Accounts 8,321 8,435 Card Services Income 10,526 9,693 Other 1,183 1,176 Noninterest Income (in-scope of ASC 606) 67,555 65,961 Noninterest Income (out-of-scope of ASC 606) 1 7,878 11,488 Total Noninterest Income $ 75,433 $ 77,449 1 The year ended December 31, 2018 includes approximately $2.9 million related to gain on sale of fixed assets. Contract Balances Receivables primarily consist of amounts due for insurance and wealth management services performed for which the Company's performance obligations have been fully satisfied. Receivables amounted to $4.7 million and $2.0 million , respectively, at December 31, 2019 , compared to $4.3 million and $1.8 million , respectively, at December 31, 2018 and were included in other assets in the Consolidated Statements of Condition. A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). The Company’s noninterest revenue streams, excluding some insurance commissions and fees, are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. As of December 31, 2019 and December 31, 2018 , the Company did not have any significant contract balances related to this transactional activity. The transaction price for an insurance entity often includes an element of consideration that is variable or contingent on the outcome of future events, such as volume of business, growth and claims experience. Consideration for this “contingent revenue” is typically paid during the first quarter of the subsequent year. ASC 606 states that variable consideration be estimated using a method that best predicts the amount of consideration to which the entity will be entitled using the approach that it expects will best predict the amount of consideration to which the entity will be entitled. This assessment would consider the terms of the contract and all reasonably available information, including historical, current, and forecast information. As of December 31, 2019 and December 31, 2018 , contract assets related to this contingent income were $2.2 million and $1.9 million , respectively. A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company often receives cash payments from customers in advance of the Company’s performance resulting in contract liabilities. These contract liabilities are classified current or long-term in the Consolidated Statements of Condition based on the timing of when the Company expects to recognize revenue. As of December 31, 2019 and December 31, 2018 , contract liabilities were $2.0 million and $1.8 million , respectively, and are included within accrued expenses in the accompanying Consolidated Statements of Condition. The liabilities include premiums due to insurance carriers in addition to unearned commission revenue. The increase in the contract liability balance during the year ended December 31, 2019 is primarily as a result of billings and cash payments received in advance of satisfying performance obligations, offset by insurance premiums and revenue recognized during the period that was included in the contract liability balance at the date of adoption. The adoption of ASC 606 did not create a change in accounting for insurance commissions and fees as they relate to contract liabilities, however the Company did eliminate the practice of deferring revenue on its larger accounts over the course of the policy period. Contract Acquisition Costs In connection with the adoption of ASC 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less . Upon adoption of ASC 606, the Company did not capitalize any contract acquisition costs.

In addition, the analysis excludes recorded deferred tax assets of $15.5 million and $12.9 million , as of December 31, 2019 and 2018 , respectively, related to employee benefit plans. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized. In assessing the need for a valuation allowance, management considers the scheduled reversal of the deferred tax liabilities, the level of historical taxable income, and the projected future taxable income over the periods in which the temporary differences comprising the deferred tax assets will be deductible. Based on its assessment, management determined that no valuation allowance was necessary at December 31, 2019 and 2018 . At December 31, 2019 and December 31, 2018 , the Company had no ASC 740-10 unrecognized tax benefits. The Company does not expect the total amount of unrecognized tax benefits to significantly increase within the next twelve months. The Company recognizes interest and penalties on unrecognized tax benefits in income tax expense in its Consolidated Statements of Income. The Company is subject to U.S. federal income tax and income tax in New York and various state jurisdictions. All tax years ending after December 31, 2015 are open to examination by the taxing authorities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities The Company, in the normal course of business, is a party to financial instruments with off-balance-sheet risk to meet the financial needs of its customers. These financial instruments include loan commitments, standby letters of credit, and unused portions of lines of credit. The contract, or notional amount, of these instruments represents the Company’s involvement in particular classes of financial instruments. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the Consolidated Statements of Condition. The Company’s maximum potential obligations to extend credit for loan commitments (unfunded loans, unused lines of credit, and standby letters of credit) outstanding on December 31 were as follows: (In thousands) 2019 2018 Loan commitments $ 149,397 $ 156,111 Standby letters of credit 30,460 21,685 Undisbursed portion of lines of credit 800,316 819,252 Total $ 980,173 $ 997,048 Commitments to extend credit (including lines of credit) are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Standby letters of credit are conditional commitments to guarantee the performance of a customer to a third party. The Company extends standby letters of credit to its customers in the normal course of business. The standby letters of credit are generally short-term. As of December 31, 2019 , the Company’s maximum potential obligation under standby letters of credit was $30.5 million . Management uses the same credit policies in making commitments to extend credit and standby letters of credit as are used for on-balance-sheet lending decisions. Based upon management’s evaluation of the counterparty, the Company may require collateral to support commitments to extend credit and standby letters of credit. The credit risk amounts are equal to the contractual amounts, assuming the amounts are fully advanced and collateral or other security is of no value. The Company does not anticipate losses as a result of these transactions. These commitments also have off-balance-sheet interest-rate risk, in that the interest rate at which these commitments were made may not be at market rates on the date the commitments are fulfilled. Since some commitments and standby letters of credit are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. At December 31, 2019 , the Company had rate lock agreements associated with mortgage loans to be sold in the secondary market (certain of which relate to loan applications for which no formal commitment has been made) amounting to approximately $1.8 million . In order to limit the interest rate risk associated with rate lock agreements, as well as the interest rate risk associated with mortgages held for sale, if any, the Company enters into agreements to sell loans in the secondary market to unrelated investors on a loan-by-loan basis. At December 31, 2019 , the Company had approximately $807,000 of commitments to sell mortgages to unrelated investors on a loan-by-loan basis.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. FASB ASC Topic 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are: Level 1 – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 – Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of December 31, 2019 and 2018 segregated by the level of valuation inputs within the fair value hierarchy used to measure fair value.

Recurring Fair Value Measurements December 31, 2018 (In thousands) Fair Value (Level 1) (Level 2) (Level 3) Available-for-sale securities U.S. Treasuries $ 289 $ 0 $ 289 $ 0 Obligations of U.S. Government sponsored entities 485,898 0 485,898 0 Obligations of U.S. states and political subdivisions 85,440 0 85,440 0 Mortgage-backed securities - residential U.S. Government agencies 128,267 0 128,267 0 U.S. Government sponsored entities 630,558 0 630,558 0 Non-U.S. Government agencies or sponsored entities 31 0 31 0 U.S. corporate debt securities 2,175 0 2,175 0 Total Available-for-sale securities 1,332,658 0 1,332,658 0 Equity securities 887 0 0 887 The Company determines fair value for its available-for-sale securities using an independent bond pricing service for identical assets or very similar securities. The pricing service uses a variety of techniques to determine fair value, including market maker bids, quotes and pricing models. Inputs to the model include recent trades, benchmark interest rates, spreads, and actual and projected cash flows. The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company’s investment portfolio consists of traditional investments, nearly all of which are U.S. Treasury obligations, federal agency bullet or mortgage pass-through securities, or general obligation municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. At least annually, the Company will validate prices supplied by the independent pricing service by comparing to prices obtained from a second third-party source. Based on the inputs used by our independent pricing services, the Company identifies the appropriate level within the fair value hierarchy to report these fair values. Certain assets are measured at fair value on a nonrecurring basis, that is, they are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. For the Company, these include loans held for sale, collateral dependent impaired loans, other real estate owned, goodwill and other intangible assets. During 2019 , certain collateral dependent impaired loans and other real estate owned at December 31, 2019 , were adjusted down to fair value. Collateral values are estimated using Level 2 inputs based upon observable market data. Real estate values are generally valued using independent appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally available in the market.

The following methods and assumptions were used in estimating fair value disclosures for financial instruments. Cash and Cash Equivalents The carrying amounts reported in the Consolidated Statements of Condition for cash, noninterest-bearing deposits, money market funds, and Federal funds sold approximate the fair value of those assets. Securities Fair values for U.S. Treasury securities are based on quoted market prices. Fair values for obligations of U.S. government sponsored entities, mortgage-backed securities-residential, obligations of U.S. states and political subdivisions, and U.S. corporate debt securities are based on quoted market prices, where available, as provided by third party pricing vendors. If quoted market prices were not available, fair values are based on quoted market prices of comparable instruments in active markets and/or based upon matrix pricing methodology, which uses comprehensive interest rate tables to determine market price, movement and yield relationships. For miscellaneous equity securities, carrying value is cost. These securities are reviewed periodically to determine if there are any events or changes in circumstances that would adversely affect their value. FHLB and FRB Stock The carrying amount of FHLB and FRB stock approximates fair value. If the stock is redeemed, the Company will receive an amount equal to the par value of the stock. Loans and Leases Fair value for loans are calculated using an exit price notion. The Company's valuation methodology takes into account factors such as estimated cash flows, including contractual cash flow and assumptions for prepayments; liquidity risk; and credit risk. The fair values of residential loans were estimated using discounted cash flow analyses, based upon available market benchmarks for rates and prepayment assumptions. The fair values of commercial and consumer loans were estimated using discounted cash flow analyses, based upon interest rates currently offered for loans and leases with similar terms and credit quality. The fair values of loans held for sale were determined based upon contractual prices for loans with similar characteristics. Accrued Interest Receivable and Accrued Interest Payable The carrying amount of these short term instruments approximate fair value. Deposits The fair values disclosed for noninterest bearing accounts and accounts with no stated maturities are equal to the amount payable on demand at the reporting date. The fair value of time deposits is based upon discounted cash flow analyses using rates offered for FHLB advances, which is the Company’s primary alternative source of funds. Securities Sold Under Agreements to Repurchase The carrying amounts of repurchase agreements and other short-term borrowings approximate their fair values. Fair values of long-term borrowings are estimated using a discounted cash flow approach, based on current market rates for similar borrowings. For securities sold under agreements to repurchase where the Company has elected the fair value option, the Company also receives pricing information from third parties, including the FHLB. Other Borrowings The fair values of other borrowings are estimated using discounted cash flow analysis, discounted at the Company’s current incremental borrowing rate for similar borrowing arrangements. For other borrowings where the Company has elected the fair value option, the Company also receives pricing information from third parties, including the FHLB. Trust Preferred Debentures The fair value of the trust preferred debentures has been estimated using a discounted cash flow analysis which uses a discount factor of a market spread over current interest rates for similar instruments.

Leases [Abstract]
Leases	Leases In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” and subsequent amendments, which replaced existing lease guidance in GAAP and requires lessees to recognize right-of-use (ROU) assets and lease liabilities on the Consolidated Statement of Condition for leases greater than twelve months and disclose key information about leasing arrangements. We adopted the standard on January 1, 2019 using the modified retrospective method and used the effective date as our date of initial application. Financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. There were no adjustments to “Retained earnings” on adoption. The new standard provides a number of optional practical expedients for transition. We elected the package of practical expedients under the transition guidance which permitted us not to reassess under the new standard our prior conclusions for lease identification and lease classification on expired or existing contracts and whether initial direct costs previously capitalized would qualify for capitalization under FASB Accounting Standards Codification (ASC) 842. We did not elect the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The new standard also provides practical expedients and recognition exemptions for an entity’s ongoing accounting policy elections. We are committed under short and long-term lease agreements for branch and ATM locations. Some of these agreements contain variable payment provisions that depend on an index or rate, initially measured using the index or rate at the lease commencement date, and are therefore not included in our future minimum lease payments. These variable lease agreements include usage-based payments for utilities, taxes, janitorial services and building maintenance. Our long-term lease agreements do not contain any material restrictive covenants. Our property leases have remaining terms of less than 1 to 23 years. Some of these leases may include options to extend the leases for up to 29 years, and some may include options to terminate the leases within 30 days. For each lease containing a renewal option, the Company considers the likelihood that the option will be exercised. Only renewal options that are reasonably assured of being exercised are included in the calculation of the ROU asset and lease liability. Operating lease amounts included in the Consolidated Statement of Condition are as follows: (In thousands) December 31, 2019 Assets Classification ROU assets Other assets $ 33,501 Liabilities Current lease liabilities Other liabilities 3,256 Non-current lease liabilities Other liabilities 32,666 Total lease liabilities $ 35,922 The components of operating lease expense, primarily included in “Net occupancy expense of premises,” were as follows: (In thousands) Year Ended December 31, 2019 Lease Costs Operating lease cost $ 4,683 Variable lease cost 466 Short-term lease cost 1 Sublease income (35 ) Total lease cost $ 5,115 At December 31, 2019, we did not have any material finance lease assets or liabilities. Other information related to operating leases was as follows: (In thousands) Year Ended December 31, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $4,680 Weighted-average remaining lease term on operating leases 13.85 Weighted-average discount rates on operating leases 3.53 % ROU assets obtained in exchange for lease liabilities $39,508 Future minimum lease payments under operating leases were as follows: (In thousands) Operating Leases 2020 $ 4,454 2021 4,106 2022 4,059 2023 3,816 2024 3,684 2025 and subsequent years 26,605 Total lease payments $ 46,724 Less: Interest (10,802 ) Present value of lease liabilities $ 35,922 At December 31, 2018, operating lease commitments under lessee arrangements were $4.8 million , $4.0 million , $3.6 million , $3.4 million , and $3.4 million for 2019 through 2023, respectively, and $13.0 million in aggregate for all years thereafter. These amounts include lease options to renew ranging from 5 to 20 years.

Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material adverse effect on the Company’s business, results of operation and financial condition. Under capital adequacy guidelines and the regulatory framework for prompt corrective action (PCA), banks must meet specific guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Capital amounts and classifications of the Company and its subsidiary banks are also subject to qualitative judgments by regulators concerning components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of common equity Tier I capital, total capital and Tier 1 capital to risk-weighted assets (as defined in the regulation), and of Tier 1 capital to average assets (as defined in the regulation). Management believes that the Company and its subsidiary banks meet all capital adequacy requirements to which they are subject. At year end 2017, the Company early adopted ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income". ASU 2018-02 permits a reclassification from accumulated other comprehensive income (loss) to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate associated with the enactment of the Tax Cuts and Jobs Act in December 2017. The amount of the reclassification was the difference between the historical corporate income tax rate of 35 percent and the newly enacted 21 percent corporate income tax rate. The adoption 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. As of December 31, 2019 , the most recent notifications from Federal bank regulatory agencies categorized Tompkins Trust Company, The Bank of Castile, Mahopac Bank, and VIST Bank as “well capitalized” under the regulatory framework for PCA. To be categorized as well capitalized, the Company and its subsidiary banks must maintain total risk-based, Tier 1 risk-based, common equity Tier 1 capital and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the capital category of the Company or its subsidiary banks. The following table presents actual and required capital ratios as of December 31, 2019 and December 31, 2018 for Tompkins and its four banking subsidiaries.

The Company’s insurance services and wealth management services are managed separately from the Banking segment. Banking The banking segment is primarily comprised of the Company's four banking subsidiaries: Tompkins Trust Company, a commercial bank with 14 banking offices operated in Ithaca, NY and surrounding communities. The Bank of Castile (DBA Tompkins Bank of Castile), a commercial bank with 16 banking offices located in the Genesee Valley region of New York State as well as Monroe County; Mahopac Bank (DBA Tompkins Mahopac Bank), a commercial bank with 14 full-service banking offices located in the counties north of New York City; and VIST Bank (DBA Tompkins VIST Bank), a banking organization with 20 banking offices headquartered and operating in Southeastern Pennsylvania. Banking services consist primarily of attracting deposits from the areas served by the Company’s banking subsidiaries and using those deposits to originate a variety of commercial loans, agricultural loans, consumer loans, real estate loans and leases in those same areas. The Company’s subsidiary banks provide a variety of retail banking services including checking accounts, savings accounts, time deposits, IRA products, residential mortgage loans, personal loans, home equity loans, credit cards, debit cards and safe deposit services delivered through its branch facilities, ATMs, voice response, mobile banking, Internet banking and remote deposit services.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis Of Presentation	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. Three of 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.
Cash and Cash Equivalents	Cash and Cash Equivalents
Securities	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. At adoption of ASU 2016-01, the Company recognized a cumulative-effect adjustment of $65,000 for the after-tax impact of the unrealized loss on equity securities. 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 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	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	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 and lease 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.
Premises and Equipment	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 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 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 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	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	Tax Credit Investments
Securities Sold Under Agreements to Repurchase	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	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	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	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	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
Comprehensive Income (Loss)	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	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	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	Revenue Recognition Tompkins adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) as of January 1, 2018 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. Under ASU 2014-09, effective January 1, 2018, 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
