SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation: The consolidated financial statements (the “financial statements”) of Bar Harbor Bankshares and its subsidiaries (the “Company” or “Bar Harbor”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Bar Harbor Bankshares is a Maine Financial Institution Holding Company for the purposes of the laws of the state of Maine, and as such, is subject to the jurisdiction of the Superintendent of the Maine Bureau of Financial Institutions. These financial statements include the accounts of the Company, its wholly-owned subsidiary Bar Harbor Bank & Trust (the "Bank") and the Bank’s consolidated subsidiaries. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless U.S. GAAP requires otherwise. Consolidation: The accompanying consolidated financial statements have been prepared in accordance with GAAP. The consolidated financial statements include the accounts of Bar Harbor Bankshares and its wholly-owned subsidiary, Bar Harbor Bank & Trust. All significant inter-company balances and transactions have been eliminated in consolidation. Assets held in a fiduciary capacity are not assets of the Company, but assets of customers, and therefore, are not included in the consolidated balance sheets. Reclassifications: Whenever necessary, amounts in the prior years’ financial statements are reclassified to conform to current presentation. The reclassifications had no impact on net income in the Company’s consolidated income statement. Stock Split: On February 21, 2017, the Company's Board of Directors declared a three-for-two stock split payable on March 21, 2017 as a large stock dividend. Shares presented in prior years have been adjusted to conform to the same basis. Use of estimates: In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, other-than-temporary impairment on securities, income tax estimates, reviews of goodwill for impairment, and accounting for post-retirement plans. Cash and Cash Equivalents: For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, Federal Funds sold, and other short-term investments with maturities less than 90 days. The Federal Reserve Bank requires the Bank to maintain certain reserve requirements of vault cash and/or deposits. The reserve requirement, included in cash and equivalents, was $15.8 million and $12.7 million at year-end 2018 and 2017 , respectively. Investment Securities: All securities held at December 31, 2018 and 2017 were classified as available-for-sale (“AFS”). Available for sale securities primarily consist of mortgage-backed securities and obligations of state and political subdivisions there of, and are carried at estimated fair value. Changes in estimated fair value of AFS securities, net of applicable income taxes, are reported in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity unless deemed to be other-than-temporarily impaired (“OTTI”) as discussed below. The Company does not have any securities classified as trading or held-to-maturity. Premiums and discounts on securities are amortized and accreted over the term of the securities using the interest method. Gains and losses on the sale of securities are recognized at the trade date using the specific-identification method and are shown separately in the Consolidated Statements of Income. Other-Than-Temporary Impairments on Investment Securities: The Company conducts an OTTI analysis of investment securities on a quarterly basis or more often if a potential loss-triggering event occurs. A write-down of a debt security is recorded when fair value is below amortized cost in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. To determine the amount related to credit loss on a debt security, the Company applies a methodology similar to that used for evaluating the impairment of loans. Federal Home Loan Bank Stock: The Bank is a member of the Federal Home Loan Bank of Boston (“FHLB”). The Bank uses the FHLB for most of its wholesale funding needs. As a requirement of membership in the FHLB, the Bank must own a minimum required amount of FHLB stock, calculated periodically based primarily on its level of borrowings from the FHLB. FHLB stock is a non-marketable equity security and therefore is reported at cost, which generally equals par value. Shares held in excess of the minimum required amount are generally redeemable at par value. The Company periodically evaluates its investment in FHLB stock for impairment based on, among other things, the capital adequacy of the FHLB and its overall financial condition. Based on the capital adequacy, liquidity position and sustained profitability of the FHLB, management believes there is no impairment related to the carrying amount of the Bank’s FHLB stock as of December 31, 2018 . Loans Held for Sale: Loans originated with the intent to be sold in the secondary market are accounted for at the lower of cost or market (fair value). Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in non-interest income. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in non-interest income or non-interest expense as earned or incurred. Loans: Loans are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest on loans is accrued and credited to income based on the principal amount of loans outstanding. Loan origination and commitment fees and direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loans’ yield, using the level-yield method over the estimated lives of the related loans. Acquired Loans: Loans acquired in acquisitions are initially recorded at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest. For loans that meet the criteria stipulated in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality,” the Company recognizes the accretable yield, which is defined as the excess of all cash flows expected at acquisition over the initial fair value of the loan, as interest income on a level-yield basis over the expected remaining life of the loan. The excess of the loan’s contractually required payments over the cash flows expected to be collected is the non-accretable difference. The non-accretable difference is not recognized as an adjustment of yield, a loss accrual, or a valuation allowance. The Company evaluates quarterly whether the timing and cash to be collected are reasonably expected. Subsequent significant increases in cash flows the Company expects to collect will first reduce any previously recognized valuation allowance and then be reflected prospectively as an increase to the level yield. Subsequent decreases in expected cash flows may result in the loan being considered impaired. Interest income is not recognized to the extent that the net investment in the loan would increase to an amount greater than the estimated payoff amount. For loans that do not meet the ASC 310-30 criteria, the Company accretes interest income based on the contractually required cash flows. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450, “Contingencies” by collectively evaluating these loans for an allowance for loan loss. Acquired loans that met the criteria for non-accrual of interest prior to the acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield. Non-performing loans: Residential real estate and home equity loans are generally placed on non-accrual status when reaching 90 days past due, or in process of foreclosure, or sooner if considered appropriate by management. Consumer loans are generally placed on non-accrual when reaching 90 days or more past due, or sooner if considered appropriate by management. Secured consumer loans are written down to net realizable value and unsecured consumer loans are charged-off upon reaching 120 days past due. Commercial real estate loans and commercial business loans that are 90 days or more past due are generally placed on non-accrual status, unless secured by sufficient cash or other assets immediately convertible to cash, and the loan is in the process of collection. Commercial real estate and commercial business loans may be placed on non-accrual status prior to the 90 days delinquency date if considered appropriate by management. When a loan has been placed on non-accrual status, previously accrued and uncollected interest is reversed against interest on the loan. The interest on non-accrual loans is accounted for using the cash-basis or cost-recovery method depending on corresponding credit risk, until qualifying for return to accrual status. A loan can be returned to accrual status when collectability of principal is reasonably assured and the loan has performed for a period of time, generally six months. Impaired loans: A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all amounts due from the borrower in accordance with the contractual terms of the loan, including scheduled interest payments. Factors considered by management in determining impairment include payment status and collateral value. In considering loans for evaluation of impairment, management generally excludes smaller balance, homogeneous loans; residential mortgage loans, home equity loans, and all consumer loans, unless such loans were restructured in a troubled debt restructuring. These loans are collectively evaluated for risk of loss. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs, and unamortized premiums or discounts), impairment is recognized by establishing or adjusting an existing allocation of the allowance for loan losses, or by recording a partial charge-off of the loan to its fair value. Interest payments made on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case, interest income may be accrued or recognized on a cash basis. Loans Modified in a Troubled Debt Restructuring: Loans are considered to have been modified in a troubled debt restructuring when, due to a borrower’s financial difficulties, the Company makes certain concessions to the borrower that it would not otherwise consider. Modifications may include interest rate reductions, principal or interest forgiveness, forbearance, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Generally, a non-accrual loan that has been modified in a troubled debt restructuring remains on non-accrual status for a period of at least 6 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 non-accrual status. Allowance for Loan Losses: The allowance for loan losses (the “allowance”) is a significant accounting estimate used in the preparation of the Company’s consolidated financial statements. The allowance is available to absorb losses inherent in the current loan portfolio and is maintained at a level that, in management’s judgment, is appropriate for the amount of risk inherent in the loan portfolio, given past and present conditions. The allowance is increased by provisions charged to operating expense and by recoveries on loans previously charged off, and is decreased by loans charged off as uncollectible. The allowance is calculated in accordance with ASC 310 - Receivables and ASC 450 - Contingencies. Under the guidance of ASC 310, specific allowances are established in cases where management has identified significant conditions or circumstances related to individual loans where the probability of a loss may be incurred. Credit loss estimates for loans without specific allowances are determined under the guidance of ASC 450, which includes portfolio segmentation based on similar risk characteristics, determination of estimated historical loss rates, calculation of a time-based loss emergence and confirmation periods, and adjustments for certain qualitative risk factors. Arriving at an appropriate level of allowance for loan losses involves a high degree of judgment. The determination of the adequacy of the allowance and provisioning for estimated losses is evaluated regularly based on review of loans, with particular emphasis on non-performing and other loans that management believes warrant special consideration. While management uses available information to recognize losses on loans, changing economic conditions and the economic prospects of the borrowers may necessitate future additions or reductions to the allowance. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance, which also may necessitate future additions or reductions to the allowance, based on information available to them at the time of their examination. Refer to Note 4 - Allowance for Loan Losses , for further information, including the Company’s loan loss estimation methodology. Reserve for Unfunded Commitments: The unfunded reserve is a component of other liabilities and represents the estimate for probable credit losses inherent in unfunded commitments to extend credit. Unfunded commitments to extend credit include banker’s acceptances, and standby and commercial letters of credit. The process used to determine the unfunded reserve is consistent with the process for determining the allowance, as adjusted for estimated funding probabilities or loan and lease equivalency factors. The level of the unfunded reserve is adjusted by recording on an expense or recovery in other noninterest expense. Reserve for unfunded commitments are classified in other liabilities on the Company’s Consolidated Balance Sheet. Premises and Equipment: Premises and equipment and related improvements are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the lesser of the lease term or estimated useful lives of related assets; generally 25 to 39 years for premises and three to seven years for furniture and equipment. Software costs are stated at cost less accumulated depreciation within other assets on the Consolidated Statements of Condition. Amortization expense is calculated using the straight-line method over the estimated useful lives of the related assets. Goodwill and Identifiable Intangible Assets: In connection with acquisitions, the Company generally records as assets on its consolidated financial statements both goodwill and identifiable intangible assets, such as core deposit intangibles. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in accordance with the purchase method of accounting for business combinations. Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, or more frequently, if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning assets and goodwill to each reporting unit. Currently, the Company’s goodwill is evaluated at the entity level as there is only one reporting unit. The Company first assesses certain qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying value. If it is more likely than not that the fair value of the reporting unit is less than the carrying value, then the fair value of each reporting unit is compared to the recorded book value “step one.” If the fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired and “step two” is not considered necessary. If the carrying value of a reporting unit exceeds its fair value, the impairment test continues (“step two”) by comparing the carrying value of the reporting unit’s goodwill to the implied fair value of goodwill. The implied fair value is computed by adjusting all assets and liabilities of the reporting unit to current fair value with the offset adjustment to goodwill. The adjusted goodwill balance is the implied fair value of the goodwill. An impairment charge is recognized if the carrying fair value of goodwill exceeds the implied fair value of goodwill. Identifiable intangible assets, included in other assets on the consolidated balance sheet, consist of core deposit intangibles amortized over their estimated useful lives on a straight-line method, which approximates the economic benefits to the Company. These assets are reviewed for impairment at least annually, or whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The determination of which intangible assets have finite lives is subjective, as is the determination of the amortization period for such intangible assets. Any negative changes in the estimates used by the Company to determine the carrying value of its goodwill and identifiable intangible assets, or which otherwise adversely affect their value or estimated lives, would adversely affect the Company’s consolidated results of operations. Bank-Owned Life Insurance: Bank-owned life insurance (“BOLI”) represents life insurance on the lives of certain current and retired employees who had provided positive consent allowing the Bank to be the beneficiary of such policies. Increases in the cash value of the policies, as well as insurance proceeds received in excess of the cash value, are recorded in other non-interest income, and are not subject to income taxes. The cash surrender value is included in other assets on the Company’s consolidated balance sheet. Other Real Estate Owned: Other real estate owned consists of properties acquired through foreclosure proceedings or acceptance of a deed-in-lieu of foreclosure. These properties are recorded at fair value less estimated costs to sell the property. If the recorded investment in the loan exceeds the property’s fair value at the time of acquisition, a charge-off is recorded against the allowance. If the fair value of the property at the time of acquisition exceeds the carrying amount of the loan, the excess is recorded either as a recovery to the allowance if a charge-off had previously been recorded, or as a gain on initial transfer in other non-interest income. Subsequent decreases in the property’s fair value and operating expenses of the property are recognized through charges to other non-interest expense. The fair value of the property acquired is based on third-party appraisals, broker price opinions, recent sales activity, or a combination thereof, subject to management judgment. Capitalized Servicing Right s : Capitalized servicing rights are recognized as assets when mortgage loans are sold and the rights to service those loans are retained. The Company’s capitalized servicing rights are accounted for under the amortization method and are initially recorded at fair value. Fair values are established by using a discounted cash flow model to calculate the present value of estimated future net servicing income. Changes in the fair value of capitalized servicing rights are primarily due to changes in valuation inputs, assumptions, and the collection and realization of expected cash flows. However, these capitalized servicing rights are amortized in proportion to and over the period of estimated net servicing income, which includes prepayment assumptions. An impairment analysis is prepared on a quarterly basis by estimating the fair value of the capitalized servicing rights and comparing that value to the carrying amount. A valuation allowance is established when the carrying amount of these capitalized servicing rights exceeds fair value. Senior and Subordinated Borrowings: The Company's borrowings include retail and wholesale repurchase agreements, FHLB overnight and short-term borrowings, Federal Funds purchased, line of credit advances and subordinated notes. The Company is required to post collateral for certain borrowings, for which it, generally, posts loans and/or investment securities as collateral. Derivative Financial Instruments: The Company recognizes all derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in the fair value of derivative instruments that are highly effective and qualify as cash flow hedge are recorded in other comprehensive income/(loss). Any ineffective portion is recorded in earnings. For fair value hedges that are highly effective, the gain or loss on the derivative and the loss or gain on the hedged item attributable to the hedged risk are both recognized in earnings, with the differences (if any) representing hedge ineffectiveness. The Company discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate. Off-Balance Sheet Financial Instruments: In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit, unused or unadvanced loan funds and letters of credit. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received. Stock Based Compensation: The Company has equity award plans that include stock option, restricted stock and performance stock, which are described more fully in Note 14 - Stock Based Compensation Plans o f the Consolidated Financial Statements. The Company expenses the grant date fair value of equity awards granted. The expense is recognized over the vesting periods of the grants. The Company uses its treasury shares for issuing shares upon option exercises, restricted stock and performance stock vesting. Accounting for Retirement Benefit Plans: The Company has non-qualified supplemental executive retirement agreements with certain retired officers. The agreements provide supplemental retirement benefits payable in installments over a period of years upon retirement or death. The Company recognized the net present value of payments associated with the agreements over the service periods of the participating officers. Interest costs continue to be recognized on the benefit obligations. The Company also has a supplemental executive retirement agreement with a certain current executive officer. This agreement provides a stream of future payments in accordance with individually defined vesting schedules upon retirement, termination, or in the event that the participating executive leaves the Company following a change of control event. The Company recognizes the net present value of payments associated with these agreements over the service periods of the participating executive officers. Upon retirement, interest costs will continue to be recognized on the benefit obligation. The Company recognizes the over-funded or under-funded status of post-retirement benefit plans as a liability on the balance sheet in other liabilities and recognizes changes in that funded status through other comprehensive income/(loss). Gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit costs are recognized in accumulated other comprehensive income/(loss), net of tax effects, until they are amortized as a component of net periodic cost. The measurement date, which is the date at which the benefit obligation and plan assets are measured, is the Company's fiscal year end. Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current available information indicates that it is more likely than not that deferred tax assets will not be realized, a valuation allowance is established. 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. Earnings Per Share: Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company, such as the Company’s dilutive stock options. Revenue Recognition: The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers." ASC 606 requires the Company to follow a five step process: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation. Revenue recognition under ASC 606 depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the goods or service. See Note 16 - Non-Interest Income of the Company's Consolidated Financial Statements for additional information on revenue recognition. Segment Reporting: An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and evaluate performance. The Company has determined that its operations are solely in the community banking industry and include traditional community banking services, including lending activities, acceptance of demand, savings and time deposits, business services, investment management, trust and third-party brokerage services. These products and services have similar distribution methods, types of customers and regulatory responsibilities. Accordingly, segment information is not presented in the Consolidated Financial Statements. Recent Accounting Pronouncements The following table provides a brief description of accounting standards that could have a material impact to the Company’s consolidated financial statements upon adoption: Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 ASU 2014-09, Revenue from Contracts with Customers This ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry topics of the Codification. The core principle of the ASU is an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU may be adopted either retrospectively or on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, upon completion of an analysis to identify all revenue streams within the scope of this accounting guidance. After reviewing the related contracts as prescribed by the five steps within this ASU, one contract resulted in recognition of a $241 thousand liability with a $184 thousand impact to retained earnings net of tax. The remaining changes had no material impact on the consolidated financial statements. See Note 11 for more detail and transitional disclosures.

Visa Class B Common Shares The Company was a member of the Visa USA payment network and was issued Class B shares in connection with the Visa Reorganization and the Visa Inc. initial public offering ("IPO") in March 2008. The Visa Class B shares are transferable only under limited circumstances until they can be converted into shares of the publicly traded class of Visa stock. This conversion cannot happen until the settlement of certain litigation, which is indemnified by Visa members. Since its initial public offering, Visa has funded a litigation reserve based upon a change in the conversion ratio of Visa Class B shares into Visa Class A shares. At its discretion, Visa may continue to increase the conversion rate in connection with any settlements in excess of amounts then in escrow for that purpose and reduce the conversion rate to the extent it adds any funds to the escrow in the future. Based on the existing transfer restriction and uncertainty of the litigation, the Company has recorded its Visa Class B shares on its consolidated balance sheets at a zero value for all reporting periods since 2008. In 2018, the Company sold all of its shares for a pre-tax gain of $2.1 million reflected in other income. As of December 31, 2017 the Company held 15,542 Visa Class B shares, which 11,623 were obtained through the original IPO and 3,919 were acquired through a business combination in early 2017. Securities Impairment As a part of the Company’s ongoing security monitoring process, the Company identifies securities in an unrealized loss position that could potentially be other-than-temporarily impaired. For the twelve months ended December 31, 2018 , 2017 and 2016 . The Company did not record any other-than-temporary impairment (“OTTI”) losses. The following table presents the remaining amount of historical credit losses on debt securities and changes reflected in the statement of income: Twelve Months Ended December 31, (in thousands) 2018 2017 2016 Estimated credit losses as of prior year-end, $ 1,697 $ 1,697 $ 3,180 Reductions for securities paid off during the period — — 1,483 Estimated credit losses at end of the period $ 1,697 $ 1,697 $ 1,697 For securities with unrealized losses, the following information was considered in determining that the impairments were not other-than-temporary: The Company expects to recover its amortized cost basis on all debt securities in its AFS portfolio, as unrealized losses are the result of changes in the interest rate environment and other market factors. Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of December 31, 2018 , prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover. The following summarizes, by investment security type, the basis for the conclusion that the debt securities in an unrealized loss position within the Company’s AFS were not other-than-temporarily impaired at December 31, 2018 : US Government-sponsored enterprises 451 out of the total 759 securities in the Company’s portfolios of AFS US Government-sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 2.9% of the amortized cost of securities in unrealized loss positions.The FNMA and FHLMC guarantee the contractual cash flows of all of the Company’s US Government-sponsored enterprises. The securities are investment grade rated and there were no material underlying credit downgrades during the year. All securities are performing. US Government agencies 117 out of the total 194 securities in the Company’s portfolios of AFS US Government agency securities were in unrealized loss positions. Aggregate unrealized losses represented 2.7% of the amortized cost of securities in unrealized loss positions. The Government National Mortgage Association (“GNMA”) guarantees the contractual cash flows of all of the Company’s US government agency securities. The securities are rated investment grade and there were no material underlying credit downgrades during the year. All securities are performing. Private-label 15 of the total 23 securities in the Company’s portfolio of AFS private-label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 0.8% of the amortized cost of securities in unrealized loss positions. Based upon the foregoing considerations, and the expectation that the Company will receive all of the future contractual cash flows related to the amortized cost on these securities, the Company does not consider there to be any additional other-than-temporary impairment with respect to these securities. Obligations of states and political subdivisions thereof 118 of the total 257 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 3.7% of the amortized cost of securities in unrealized loss positions. The Company continually monitors the municipal bond sector of the market carefully and periodically evaluates the appropriate level of exposure to the market. At this time, the Company believes the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for that risk. There were no material underlying credit downgrades during the year. All securities are performing. Corporate bonds 10 of the total 21 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 2.4% of the amortized cost of bonds in unrealized loss positions. The Company reviews the financial strength of all of these bonds and has concluded that the amortized cost remains supported by the expected future cash flows of these securities.

Commercial real estate loans include multi-family, commercial construction and land, and other commercial real estate classes. Commercial and industrial loans include loans to commercial businesses, agricultural and other loans to farmers, and tax exempt loans. Residential real estate loans consist of mortgages for 1-to-4 family housing. Consumer loans include home equity loans, auto and other installment loans. The Company’s lending activities are principally conducted in Maine, New Hampshire, and Vermont. Total loans include business activity loans and acquired loans. Acquired loans are those loans previously acquired from a business combination. The following is a summary of total loans as of December 31, 2018 and December 31, 2017 : December 31, 2018 December 31, 2017 (in thousands) Business Activities Loans Acquired Loans Total Business Activities Loans Acquired Loans Total Commercial real estate: Construction and land development $ 23,754 $ 2,890 $ 26,644 $ 28,892 $ 16,781 $ 45,673 Other commercial real estate 555,980 244,075 800,055 505,119 275,954 781,073 Total commercial real estate 579,734 246,965 826,699 534,011 292,735 826,746 Commercial and industrial: Other Commercial 234,757 52,470 287,227 198,051 68,069 266,120 Agricultural 22,317 — 22,317 27,588 — 27,588 Tax exempt 56,588 38,738 95,326 42,365 43,350 85,715 Total commercial and industrial 313,662 91,208 404,870 268,004 111,419 379,423 Total commercial loans 893,396 338,173 1,231,569 802,015 404,154 1,206,169 Residential real estate: Residential mortgages 670,189 474,509 1,144,698 591,411 564,271 1,155,682 Total residential real estate 670,189 474,509 1,144,698 591,411 564,271 1,155,682 Consumer: Home equity 57,898 45,291 103,189 51,376 62,217 113,593 Other consumer 9,414 1,357 10,771 7,828 2,341 10,169 Total consumer 67,312 46,648 113,960 59,204 64,558 123,762 Total loans $ 1,630,897 $ 859,330 $ 2,490,227 $ 1,452,630 $ 1,032,983 $ 2,485,613 Total unamortized net premiums included in the year-end total for business activity loans were the following at December 31, 2018 and December 31, 2017 : (in thousands) 2018 2017 Unamortized net loan origination costs $ 3,064 $ 2,445 Unamortized net premium on purchased loans (127 ) (123 ) Total unamortized net costs and premiums $ 2,937 $ 2,322 For the year ended December 31, 2018 , the Company had pledged loans with a collateral value totaling $96.3 million to the Federal Reserve Bank of Boston for certain borrowing arrangements. The Company also pledged residential first mortgage loans, home equity loans and certain commercial loans with collateral value totaling $986.2 million for FHLB borrowings for the year ended December 31, 2018 . (See Note 8 - Borrowed Funds of the Company's Consolidated Financial Statements.) The carrying amount of the acquired loans at December 31, 2018 totaled $859.3 million . A subset of these loans was determined to have evidence of credit deterioration at the acquisition date, which is accounted for in accordance with ASC 310-30. These purchased credit-impaired loans presently maintain a carrying value of $10.1 million (and a note balance of $14.0 million ). These loans are evaluated for impairment through the periodic reforecasting of expected cash flows. Loans considered not impaired at acquisition date had a carrying amount of $849.2 million .

Troubled Debt Restructuring ("TDR"), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as non-performing at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months . TDRs are evaluated individually for impairment and may result in a specific allowance amount allocated to an individual loan. The following tables include the recorded investment and number of modifications identified during the twelve months ended December 31, 2018 , 2017 and 2016, respectively. The table includes the recorded investment in the loans prior to a modification and also the recorded investment in the loans after the loans were restructured. Modifications may include adjustments to interest rates, payment amounts, extensions of maturity, court ordered concessions or other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral.

The evaluation of certain loans individually for specific impairment includes loans that were previously classified as TDRs or continue to be classified as TDRs. Residential Mortgage Foreclosure and Other Real Estate Owned As of December 31, 2018 , the Company maintained bank-owned residential real estate property with a fair value of $2.4 million . Additionally, residential mortgage loans collateralized by real estate property that were in the process of foreclosure as of December 31, 2018 and December 31, 2017 totaled $1.5 million and $843 thousand , respectively. As of December 31, 2017 , bank-owned non-residential real estate property totaling $90 thousand . Loan Concentrations Loan concentrations in specific industries may occasionally emerge as a result of economic conditions, changes in local demands, natural loan growth and runoff. At December 31, 2018 the largest industry concentration outside of commercial real estate was the hospitality industry which represents 9.0% or $223.0 million of the Company's total loan portfolio, compared with 9.4% or $234.6 million at December 31, 2017 . There were no concentrations of loans related to any single industry in excess of 10% of total loans for 2018 or 2017 . Loans to Related Parties In the ordinary course of business, the Bank has made loans at prevailing rates and terms to directors, officers and other related parties. In management’s opinion, such loans do not present more than the normal risk of collectability or incorporate other unfavorable features, and were made under terms that are consistent with the Bank’s lending policies. Loan to related parties at December 31, 2018 and December 31, 2017 are summarized below. (in thousands) 2018 2017 Beginning balance $ 10,487 $ 10,620 Changes in composition (1) — 249 New Loans — 1,124 Less: repayments (2,092 ) (1,506 ) Ending balance $ 8,395 $ 10,487 ______________________________________ (1) Adjustments to reflect changes in status of directors and officers for each year presented. Mortgage Banking The Bank sells loans in the secondary market and retains the ability to service many of these loans. The Bank earns fees for the servicing provided. At year end 2018 and 2017 , the Company was servicing loans for participants totaling $496.5 million and $497.9 million , respectively. Loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in servicing assets relate primarily to changes in prepayments that result from shifts in interest rates. Contractually-specified servicing fees were $1.3 million , $1.2 million , and $28 thousand for the years ended 2018 , 2017 , and 2016 , respectively, and is included as a component of other income within non-interest income. Servicing rights activity during 2018 and 2017 was as follows: At or for the Twelve Months Ended December 31, (in thousands) 2018 2017 Balance at beginning of year $ 3,232 $ 5 Acquired — 3,417 Additions 99 134 Amortization (245 ) (324 ) Balance at end of year $ 3,086 $ 3,232 Total residential loans included held for sale loans of $168 thousand and $13.4 million at December 31, 2018 and 2017 , respectively. The net gains on sales of loans at December 31, 2018 and 2017 were $121 thousand and $222 thousand , respectively, and included as a component of other income within non-interest income.

ALLOWANCE FOR LOAN LOSSES

ALLOWANCE FOR LOAN LOSSES	12 Months Ended
	Dec. 31, 2018
Receivables [Abstract]
ALLOWANCE FOR LOAN LOSSES	ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is maintained at a level considered adequate to provide for an estimate of probable credit losses inherent in the loan portfolio. The allowance is increased by the provision charged to operating expense and reduced by net charge-offs. Loans are charged against the allowance for loan losses when the Company believes collectability has declined to a point where there is a distinct possibility of some loss of principal and interest. While the Company uses the best information available to make the evaluation, future adjustments may be necessary if there are significant changes in conditions. The allowance is comprised of four distinct reserve components: (1) specific reserves related to loans individually evaluated; (2) quantitative reserves related to loans collectively evaluated; (3) qualitative reserves related to loans collectively evaluated; and (4) a temporal estimate is made for incurred loss emergence period for each loan category within the collectively evaluated pools. A summary of the methodology employed on a quarterly basis with respect to each of these components in order to evaluate the overall adequacy of the Company's allowance for loan losses is as follows: Specific Reserve for Loans Individually Evaluated First, the Company identifies loan relationships having aggregate balances in excess of $150 thousand with potential credit weaknesses. Such loan relationships are identified primarily through the Company's analysis of internal loan evaluations, past due loan reports, TDRs and loans adversely classified. Each loan so identified is then individually evaluated for impairment. Loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the original loan agreement. Substantially all impaired loans have historically been collateral dependent, meaning repayment of the loan is expected or is considered to be provided solely from the sale of the loan's underlying collateral. For such loans, the Company measures impairment based on the fair value of the loan's collateral, which is generally determined utilizing current appraisals. A specific reserve is established in an amount equal to the excess, if any, of the recorded investment in each impaired loan over the fair value of its underlying collateral, less estimated costs to sell. The Company's policy is to re-evaluate the fair value of collateral dependent loans at least every twelve months unless there is a known deterioration in the collateral's value, in which case a new appraisal is obtained. Purchase credit impaired (“PCI”) loans are collectively evaluated, but are not included in the general reserve as described below. The evaluation of the PCI loans requires continued quarterly assessment of key assumptions and estimates similar to the initial fair value estimate, including changes in the severity of loss, timing and speed of payments, collateral value changes, expected cash flows and other relevant factors. The quarterly assessment is compared to the initial fair value estimate and a determination is made if an adjustment to the allowance for loan loss is deemed necessary. Quantitative Reserve for Loans Collectively Evaluated Second, the Company stratifies the loan portfolio into two general business loan pools: substandard (7 risk rated) and pass-rated (0 to 6 rated) by loan type. Substandard rated loans are subject to higher credit loss rates in the allowance for loan loss calculation. The Company utilizes historical loss rates for commercial real estate and commercial and industrial loans assessed by internal risk rating. Historical loss rates on residential real estate and consumer loans are not risk graded. Residential real estate and consumer loans are considered as part of the pass-rated portfolio unless removed due to specific reserve evaluation based on past due status and/or other indications of credit deterioration. Quantitative reserves relative to each loan pool are established as follows: for all loan segments an allocation equaling 100% of the respective pool's average 3-year historical net loan charge-off rate (determined based upon the most recent 12 quarters) is applied to the aggregate recorded investment in the pool of loans. Purchased performing loans are collectively evaluated as their own separate category within each loan pool. Qualitative Reserve for Loans Collectively Evaluated Third, the Company considers the necessity to adjust the average historical net loan charge-off rates relative to each of the above two loan pools for potential risks factors that could result in actual losses deviating from prior loss experience. Such qualitative risk factors considered are: (1) lending policies and procedures, (2) business conditions, (3) volume and nature of the loan portfolio, (4) experience, ability and depth of lending management, (5) problem loan trends, (6) quality of the Company’s loan review system, (7) concentrations in the loan portfolio, (8) competition, legal, and regulatory environment and (9) collateral coverage and loan-to-value. Loss Emergence Period for Loans Collectively Evaluated Fourth, the general allowance related to loans collectively evaluated includes an estimate of incurred losses over an estimated loss emergence period ("LEP"). The LEP is generated utilizing a charge-off look-back analysis, which evaluates the time from the first indication of elevated risk of repayment (or other early event indicating a problem) to eventual charge-off to support the LEP considered in the allowance calculation. This reserving methodology establishes the approximate number of months of LEP that represents incurred losses for each loan portfolio within each portfolio segment in addition to the qualitative reserves. Activity in the allowance for loan losses for the twelve months ended December 31, 2018 , 2017 and 2016 was as follows: Business Activities Loans At or for the Twelve Months Ended December 31, 2018 (in thousands) Commercial real estate Commercial and industrial Residential real estate Consumer Total Balance at beginning of period $ 6,037 $ 2,373 $ 3,357 $ 386 $ 12,153 Charged-off loans (417 ) (111 ) (225 ) (629 ) (1,382 ) Recoveries on charged-off loans 275 76 166 18 535 Provision/(releases) for loan losses 916 42 684 633 2,275 Balance at end of period $ 6,811 $ 2,380 $ 3,982 $ 408 $ 13,581 Individually evaluated for impairment 422 78 111 — 611 Collectively evaluated 6,389 2,302 3,871 408 12,970 Total $ 6,811 $ 2,380 $ 3,982 $ 408 $ 13,581 Acquired Loans At or for the Twelve Months Ended December 31, 2018 (in thousands) Commercial real estate Commercial and industrial Residential real estate Consumer Total Balance at beginning of period $ 97 $ 16 $ 59 $ — $ 172 Charged-off loans (136 ) (166 ) (158 ) (65 ) (525 ) Recoveries on charged-off loans 43 7 — 83 133 Provision/(releases) for loan losses 169 178 176 (18 ) 505 Balance at end of period $ 173 $ 35 $ 77 $ — $ 285 Individually evaluated for impairment — — 41 — 41 Collectively evaluated 173 35 36 — 244 Total $ 173 $ 35 $ 77 $ — $ 285 Business Activities Loans At or for the Twelve Months Ended December 31, 2017 (in thousands) Commercial real estate Commercial and industrial Residential real estate Consumer Total Balance at beginning of period $ 5,145 $ 1,952 $ 2,721 $ 601 $ 10,419 Charged-off loans (124 ) (189 ) (226 ) (162 ) (701 ) Recoveries on charged-off loans 49 11 65 18 143 Provision/(releases) for loan losses 967 599 797 (71 ) 2,292 Balance at end of period $ 6,037 $ 2,373 $ 3,357 $ 386 $ 12,153 Individually evaluated for impairment 447 3 9 — 459 Collectively evaluated 5,590 2,370 3,348 386 11,694 Total $ 6,037 $ 2,373 $ 3,357 $ 386 $ 12,153 Acquired Loans At or for the Twelve Months Ended December 31, 2017 (in thousands) Commercial real estate Commercial and industrial Residential real estate Consumer Total Balance at beginning of period $ — $ — $ — $ — $ — Charged-off loans (151 ) (18 ) (29 ) (127 ) (325 ) Recoveries on charged-off loans 1 — — — 1 Provision/(releases) for loan losses 247 34 88 127 496 Balance at end of period $ 97 $ 16 $ 59 $ — $ 172 Individually evaluated for impairment — — — — — Collectively evaluated 97 16 59 — 172 Total $ 97 $ 16 $ 59 $ — $ 172 Business Activities Loans At or for the Twelve Months Ended December 31, 2016 (in thousands) Commercial real estate Commercial and industrial Residential real estate Consumer Total Balance at beginning of period $ 4,430 $ 1,590 $ 2,747 $ 672 $ 9,439 Charged-off loans (133 ) (90 ) (141 ) (47 ) (411 ) Recoveries on charged-off loans 40 289 44 39 412 Provision/(releases) for loan losses 808 163 71 (63 ) 979 Balance at end of period $ 5,145 $ 1,952 $ 2,721 $ 601 $ 10,419 Individually evaluated for impairment 193 173 49 9 424 Collectively evaluated 4,952 1,779 2,672 592 9,995 Total $ 5,145 $ 1,952 $ 2,721 $ 601 $ 10,419 There were no loans meeting the definition of acquired for the twelve month period ended December 31, 2016 . Credit Quality Information Loan Origination/Risk Management: The Company has certain lending policies and procedures in place designed to maximize loan income within an acceptable level of risk. The Company’s Board of Directors reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management and the Company's Board of Directors with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans and potential problem loans. The Company seeks to diversify the loan portfolio as a means of managing risk associated with fluctuations in economic conditions. Credit Quality Indicators/Classified Loans: In monitoring the credit quality of the portfolio, management applies a credit quality indicator and uses an internal risk rating system to categorize commercial loans. These credit quality indicators range from one through nine, with a higher number correlating to increasing risk of loss. These ratings are used as inputs to the calculation of the allowance for loan losses. Consistent with regulatory guidelines, the Company provides for the classification of loans which are considered to be of lesser quality as special mention, substandard, doubtful, or loss (i.e. risk rated 6, 7, 8 and 9, respectively). The following are the definitions of the Company’s credit quality indicators: Pass: Loans the Company considers in the commercial portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes there is a low risk of loss related to these loans considered pass rated. Special Mention: Loans the Company considers having some potential weaknesses, but are deemed to not carry levels of risk inherent in one of the subsequent categories, are designated as special mention. A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. This might include loans which may require a higher level of supervision or internal reporting because of: (i) declining industry trends; (ii) increasing reliance on secondary sources of repayment; (iii) the poor condition of or lack of control over collateral; or (iv) failure to obtain proper documentation or any other deviations from prudent lending practices. Economic or market conditions which may, in the future, affect the obligor, may warrant special mention of the asset. Loans for which an adverse trend in the borrower's operations or an imbalanced position in the balance sheet which has not reached a point where the liquidation is jeopardized may be included in this classification. Special mention loans are not adversely classified and do not expose the Company to sufficient risks to warrant classification. Substandard: Loans the Company considers as substandard are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Substandard loans have a well-defined weakness that jeopardizes liquidation of the debt. Substandard loans include those loans where there is the distinct possibility of some loss of principal, if the deficiencies are not corrected. Doubtful: Loans the Company considers as doubtful have all of the weaknesses inherent in those loans that are classified as substandard. These loans have the added characteristic of a well-defined weakness which is inadequately protected by the current sound worth and paying capacity of borrower or of the collateral pledged, if any, and calls into question the collectability of the full balance of the loan. The possibility of loss is high but because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the loan, its classification as loss is deferred until its more exact status is determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. The entire amount of the loan might not be classified as doubtful when collection of a specific portion appears highly probable. Loans are generally not classified doubtful for an extended period of time (i.e., over a year). Loss: Loans the Company considers as losses are those considered uncollectible and of such little value that their continuance as an asset is not warranted and the uncollectible amounts are charged-off. This classification does not mean the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this worthless asset even though partial recovery may be affected in the future. Losses are taken in the period in which they are determined to be uncollectible.

The Company also maintains a $1.0 million secured line of credit with the FHLB that bears a daily adjustable rate calculated by the FHLB. There was no outstanding balance on the FHLB line of credit for the years ended December 31, 2018 and 2017 . The Bank also has capacity to borrow funds on a secured basis utilizing the Borrower in Custody program and the Discount Window at the Federal Reserve Bank of Boston (the “FRB”). At December 31, 2018 , the Bank’s available secured line of credit at the FRB was $118.6 million. The Bank has pledged certain loans and securities to the FRB to support this arrangement. There were no borrowings with the FRB for the periods ended December 31, 2018 and December 31, 2017 . Long-term FHLB advances consist of advances with a maturity of more than one year. The advances outstanding at December 31, 2018 include no callable advances and $330 thousand of amortizing advances. The advances outstanding at December 31, 2017 include callable advances totaling $27.0 million , and $683.0 thousand of amortizing advances. All FHLB borrowings, including the line of credit, are secured by a blanket security agreement on certain qualified collateral, principally all residential first mortgage loans and certain securities. A summary of maturities of FHLB advances as of December 31, 2018 is as follows: December 31, 2018 (in thousands, except rates) Amount Weighted Fixed rate advances maturing: 2019 $ 611,683 2.47 % 2020 29,956 1.87 2021 1,648 2.34 2022 — — 2023 1,000 — 2024 and thereafter 325 3.97 Total FHLB advances $ 644,612 2.44 % In April 2008, the Bank issued fifteen year junior subordinated notes in the amount of $5.0 million due in 2023. These debt securities qualify as Tier 2 capital for the Company and the Bank. The subordinated debt securities are callable by the Bank after five years without penalty. The interest rate is three-month LIBOR plus 3.45% . At December 31, 2018 and December 31, 2017 the interest rate was 6.24% and 5.04% , respectively. The Company has $17.0 million of subordinated debt issued on October 29, 2014, in connection with the execution of a Subordinated Note Purchase Agreement with an aggregate of $17.0 million of subordinated notes (the “Notes”) to the accredited investors. The Notes have a maturity date of November 1, 2024, and will bear interest at a fixed rate of 6.75% per annum. The Company may, at its option, beginning with the interest payment date of November 1, 2019, and on any interest payment date thereafter, redeem the Notes, in whole or in part, at par plus accrued and unpaid interest to the date of redemption. Any partial redemption will be made pro rata among all of the noteholders. The Notes are not subject to repayment at the option of the noteholders. The Notes are unsecured, subordinated obligations of the Company and rank junior in right of payment to the Company’s senior indebtedness and to the Company’s obligations to its general creditors. The Company also has $20.6 million in floating Junior Subordinated Deferrable Interest Debentures (“Debentures”) issued by NHTB Capital Trust II (“Trust II”) and NHTB Capital Trust III (“Trust III”), which are both Connecticut statutory trusts. The Debentures were issued on March 30, 2014, carry a variable interest rate of three-month LIBOR plus 2.79% , and mature in 2034. The debt is callable by the Company at the time when any interest payment is made. Trust II and Trust III are considered variable interest entities for which the Company is not the primary beneficiary. Accordingly, Trust II and Trust III are not consolidated into the Company’s financial statements.

The following tables set forth information about the plan for the year ended December 31, 2018 and 2017 : (in thousands) 2018 2017 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 9,020 $ 8,642 Service cost — — Interest cost 315 334 Actuarial (gain) loss (771 ) 662 Benefits paid (291 ) (269 ) Settlements (264 ) (349 ) Projected benefit obligation at end of year 8,009 9,020 Change in fair value of plan assets: Fair value of plan assets at beginning of year 11,026 10,622 Expected return on plan assets (481 ) 1,022 Contributions by employer — — Benefits paid (291 ) (269 ) Settlements (264 ) (349 ) Fair value of plan assets at end of year 9,990 11,026 Overfunded status $ (1,981 ) $ (2,006 ) Amounts recognized in consolidated balance sheet: Other assets $ 1,981 $ 2,006 Net periodic pension cost is comprised of the following for the year ended December 31, 2018 and 2017 : (in thousands) 2018 2017 Interest cost $ 315 $ 334 Expected return on plan assets (706 ) (706 ) Settlement Charge — 13 Net periodic pension benefit cost (credit) $ (391 ) $ (359 ) (in thousands) 2018 2017 Net actuarial loss (gain) $ 415 $ 346 Settlement charge — (13 ) Net period pension benefit cost (credit) (391 ) (359 ) Total recognized in net periodic benefit cost (credit) and other comprehensive loss (income) $ 24 $ (26 ) Change in plan assets and benefit obligations recognized in accumulated other comprehensive income as of December 31, 2018 and 2017 are as follows: (in thousands) 2018 2017 Net actuarial loss (gain) $ 415 $ 346 Settlement charge — (13 ) Prior service cost (credit) 333 — Total accumulated other comprehensive loss (pre-tax) $ 748 $ 333 The after tax components of accumulated other comprehensive loss, which have not yet been recognized in net periodic pension cost, related to the Plan are a net loss of $573 thousand. The Company expects to make no cash contributions to the pension trust during the 2019 fiscal year. The amount expected to be amortized from accumulated other comprehensive loss into net periodic pension cost over the next fiscal year is zero . The principal actuarial assumptions used at December 31, 2018 and 2017 were as follows: 2018 2017 Projected benefit obligation Discount rate 4.23 % 3.56 % Net periodic pension cost Discount rate 3.56 % 4.09 % Long-term rate of return on plan assets 6.50 7.00 The discount rate that is used in the measurement of the pension obligation is determined by comparing the expected future retirement payment cash flows of the plan to the Citigroup Above Median Double-A Curve as of the measurement date. The expected long-term rate of return on Plan assets reflects expectations of future returns as applied to the plan’s target allocation of asset classes. In estimating that rate, appropriate consideration was given to historical returns earned by equities and fixed income securities. The Company’s overall investment strategy with respect to the Plan’s assets is to maintain assets at a level that will sufficiently cover future beneficiary obligations while achieving long term growth in assets. The Plan’s targeted asset allocation is 48% equity securities and 52% fixed-income securities primarily consisting of intermediate-term products. The fair values for investment securities are determined by quoted prices in active markets, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). The fair value of the Plan's assets by category and level within fair value hierarchy are as follows at December 31, 2018 and 2017 : 2018 (in thousands) Total Level 1 Level 2 Asset Category Equity mutual funds: Large-cap $ 1,730 $ 1,730 $ — Mid-cap 477 477 — Small-cap 469 469 — International 845 845 Fixed income funds: Fixed-income - core plus 3,945 3,945 — Intermediate duration 1,321 1,321 — Common stock 506 506 — Common/collective trusts - large-cap 469 — 469 Cash equivalents - money market 228 228 — Total $ 9,990 $ 9,521 $ 469 2017 (in thousands) Total Level 1 Level 2 Asset Category Equity mutual funds: Large-cap $ 2,143 $ 2,143 $ — Mid-cap 612 612 — Small-cap 613 613 — International 1,150 1,150 Fixed income funds: Fixed-income - core plus 3,896 3,896 — Intermediate duration 1,316 1,316 — Common stock 610 610 — Common/collective trusts - large-cap 555 — 555 Cash equivalents - money market 130 130 — Total $ 11,025 $ 10,470 $ 555 The Plan did not hold any assets classified as Level 3, and there were no transfers between levels during 2018 and 2017 . Estimated benefit payments under the Company's pension plan over the next 10 years at December 31, 2018 are as follows: Year Payments in Thousands 2019 $ 357 2020 383 2021 382 2022 400 2023 396 2024-2028 2,239 Non-qualified Supplemental Executive Retirement Plan The Company has non-qualified supplemental executive retirement agreements with certain retired officers. The agreements provide supplemental retirement benefits payable in installments over a period of years upon retirement or death. This agreement provides a stream of future payments in accordance with individually defined vesting schedules upon retirement, termination, or in the event that the participating executive leaves the Company following a change of control event. The following table sets forth changes in benefit obligation, changes in plan assets, and the funded status of the plan as of and for the years ended December 31, 2018 and December 31, 2017 : (in thousands) 2018 2017 Change in benefit obligation: Projected benefit obligation at beginning of year $ 3,451 $ 3,670 Service cost — — Interest cost 102 116 Actuarial loss/(gain) (142 ) 16 Benefits paid (378 ) (351 ) Projected benefit obligation at end of year $ 3,033 $ 3,451 Change in fair value of plan assets: Fair value of plan assets at beginning of year $ — $ — Expected return on plan assets — — Contributions by employer 378 351 Benefits paid (378 ) (351 ) Fair value of plan assets at end of year $ — $ — Underfunded status $ 3,033 $ 3,451 Amounts recognized in consolidated balance sheet Other liabilities $ 3,033 $ 3,451 Net periodic benefit cost is comprised of the following for the years ended December 31, 2018 and 2017 : (in thousands) 2018 2017 Interest cost $ 102 $ 116 Expected return on plan assets — — Amortization of unrecognized actuarial loss 29 21 Net periodic benefit cost $ 131 $ 137 (in thousands) 2018 2017 Net actuarial loss (gain) $ (142 ) $ 16 Amortization of unrecognized actuarial loss (29 ) (21 ) Total recognized in net periodic benefit cost and other comprehensive loss $ (171 ) $ (5 ) Change in plan assets and benefit obligations recognized in accumulated other comprehensive income in 2018 and 2017 are as follows: (in thousands) 2018 2017 Accumulated other comprehensive income at beginning of the year (pre-tax) $ 585 $ 590 Actuarial loss (gain) (142 ) 16 Amortization of actuarial loss (29 ) (21 ) Accumulated other comprehensive income at end of year (pre-tax) $ 414 $ 585 The after tax components of accumulated other comprehensive loss, which have not yet been recognized in net periodic benefit cost, related to the non-qualified supplemental executive retirement agreements are a net loss of $ 317 thousand. The amount expected to be amortized from accumulated other comprehensive income into net periodic benefit cost over then next fiscal year is $15 thousand. The principal actuarial assumptions used at December 31, 2018 and December 31, 2017 were as follows: 2018 2017 Discount rate beginning of year 3.13 % 3.31 % Discount rate end of year 3.83 3.13 The discount rate used in the measurement of the non-qualified supplemental executive retirement plan obligation is determined by comparing the expected future retirement payment cash flows to the Citigroup Above Median Double-A Curve as of the measurement date. The Company expects to contribute the following amounts to fund benefit payments under the supplemental executive retirement plans: (in thousands) Payments 2019 $ 378 2020 293 2021 260 2022 260 2023 260 2024-2036 2,518 401(k) Plan The Company maintains a Section 401(k) savings plan for substantially all of its employees. Employees are eligible to participate in the 401(k) Plan on the first day of any quarter following their date of hire and attainment of age 21 ½ . Under the plan, the Company makes a matching contribution of a portion of the amount contributed by each participating employee, up to a percentage of the employee’s annual salary. The plan allows for supplementary profit sharing contributions by the Company, at its discretion, for the benefit of participating employees. The total expense for this plan in 2018 , 2017 , and 2016 was $ 1.0 million , $ 970 thousand, and $ 439 thousand, respectively.

The net deferred tax asset, which is included in other assets, amounted to $ 9.5 million at December 31, 2018 and $ 7.2 million at December 31, 2017 . The significant components of deferred tax assets and liabilities at December 31, 2018 and December 31, 2017 were as follows: 2018 2017 (in thousands) Assets Liabilities Assets Liabilities Allowance for loan losses $ 3,085 $ — $ 2,729 $ — Deferred compensation 3,242 — 3,333 — Unrealized gain or loss on securities available for sale 2,641 — 649 — Unrealized gain or loss on derivatives 685 — 853 — Depreciation — 1,517 — 1,356 Deferred loan origination costs — 725 — 655 Non-accrual interest 374 — 273 — Branch acquisition costs and goodwill — 784 — 737 Core deposit intangible — 1,309 — 1,525 Acquisition fair value adjustments 3,171 — 4,000 — Prepaid expenses — 215 — 302 Interest rate cap premium amortization — 257 — 276 Mortgage servicing rights — 721 — 769 Equity compensation 335 — 297 — Prepaid pension — 366 — 345 Contract incentives 1,658 — 594 — Other 217 — 417 — Total $ 15,408 $ 5,894 $ 13,145 $ 5,965 The Company has determined that a valuation allowance is not required for its net deferred tax asset since it is more likely than not that this asset is realizable principally through future taxable income and future reversal of existing temporary differences. The Company is subject to income tax in the U.S. federal jurisdiction and also in the states of Maine, New Hampshire and Massachusetts. The Company is no longer subject to examination by taxing authorities for years before 2015. On December 22, 2017, H.R.1, commonly known as the Tax Cuts and Jobs Act (the “Act”), was signed into law. The Act included several provisions affecting the Company's federal income tax expense, including the reduced federal income tax rate from 35% to 21% effective January 1, 2018. As a result of this rate reduction, the Company was required to re-measure, through income tax expense in the period of enactment, the deferred tax assets and liabilities using the enacted rate at which these items are expected to be recovered or settled. The re-measurement of the Company's net deferred tax asset resulted in additional 2017 income tax expense of $ 4.0 million. Also on December 22, 2017, the U.S. Securities and Exchange Commission (“SEC”) released Staff Accounting Bulletin No. 118 (“SAB 118”) which addressed any uncertainty or diversity of views in practice in accounting for the income tax effects of the Act in situations where a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete this accounting in the reporting period that includes the enactment date. SAB 118 allows for a measurement period not to extend beyond one year from the Act’s enactment date to complete the necessary accounting. As of December 31, 2017 the Company's $ 1.4 million deferred tax liability for temporary differences between the tax and financial reporting bases of fixed assets was recorded as a provisional amount based upon reasonable estimates. The final determination of this deferred tax liability was awaiting completion of a cost segregation analysis to determine the impact of applying accelerated tax depreciation to certain building costs, including application of the Act's new provisions for 100% bonus depreciation. Also as of December 31, 2017, the Company made no adjustments to deferred tax assets representing future deductions for accrued compensation that may be subject to new limitations under Internal Revenue Code Section 162(m) which, generally, limits the annual deduction for certain compensation paid to certain employees to $ 1.0 million . All of these matters were finalized in 2018 with no material impact to the Company's federal income tax expense.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES As part of its overall asset and liability management strategy, the Company periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Company’s interest rate risk management strategy involves modifying the re-pricing characteristics of certain assets or liabilities so the changes in interest rates do not have a significant effect on net interest income. The Company recognizes its derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in fair value of derivative instruments that are highly effective and qualify as cash flow hedges are recorded in other comprehensive income or loss. Any ineffective portion is recorded in earnings. The Company discontinues hedge accounting when it is determined the derivative is no longer effective in offsetting changes of the hedged risk on the hedged item, or management determines the designation of the derivative as a hedging instrument is no longer appropriate. Information about derivative assets and liabilities at December 31, 2018 and December 31, 2017 , follows: December 31, 2018 Notional Amount Weighted Average Maturity Estimated Fair Value Asset (Liability) (in thousands) (in years) (in thousands) Cash flow hedges: Interest rate caps agreements $ 90,000 4.1 $ 803 Total cash flow hedges 90,000 4.1 803 Non-hedging derivatives: Interest rate lock commitments 957 0.1 8 Customer loan derivative liability 45,641 9.9 (1,353 ) Customer loan derivative asset 45,641 9.9 1,353 Total non-hedging derivatives 92,239 8 Total $ 182,239 $ 811 December 31, 2017 Notional Amount Weighted Average Maturity Estimated Fair Value Asset (Liability) (in thousands) (in years) (in thousands) Cash flow hedges: Interest rate caps agreements $ 90,000 5.1 $ 669 Total cash flow hedges 90,000 669 Economic hedges: Forward sale commitments 20,352 0.2 (221 ) Total economic hedges 20,352 (221 ) Non-hedging derivatives: Interest rate lock commitments 19,853 0.2 (1 ) Total non-hedging derivatives 19,853 (1 ) Total $ 130,205 $ 447 Information about derivative assets and liabilities for December 31, 2018 and December 31, 2017 , follows: Twelve Months Ended December 31, (in thousands) 2018 2017 Cash flow hedges: Interest rate cap agreements Realized in interest expense $ (519 ) $ (257 ) Economic hedges: Forward commitments Realized gain (loss) in other non-interest income 221 (77 ) Non-hedging derivatives: Interest rate lock commitments Realized gain (loss) in other non-interest income 9 (22 ) Cash flow hedges In 2014, interest rate cap agreements were purchased to limit the Company’s exposure to rising interest rates on four rolling, three-month borrowings indexed to three-month LIBOR. Under the terms of the agreements, the Company paid total premiums of $4.6 million for the right to receive cash flow payments if three-month LIBOR rises above the caps of 3.00% , thus effectively ensuring interest expense on the borrowings at maximum rates of 3.00% for the duration of the agreements. The interest rate cap agreements were designated as cash flow hedges. The fair values of the interest rate cap agreements are included in other assets on the Company’s consolidated balance sheets. Changes in the fair value, representing unrealized gains or losses, are recorded in accumulated other comprehensive income, net of tax. The premiums paid on the interest rate cap agreements are being recognized as increases in interest expense over the duration of the agreements using the caplet method. Economic hedges The Company utilizes forward sale commitments to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans originated for sale. The forward sale commitments are accounted for as derivatives with changes in fair value recorded in current period earnings. The Company typically uses mandatory delivery contracts, which are loan sale agreements where the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, the Company may enter into mandatory delivery contracts shortly after the loan closes with a customer. Non-hedging derivatives Interest rate lock commitments The Company enters into interest rate lock commitments (“IRLCs”) for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs relate to the origination of residential mortgage loans that are held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in non-interest income in the Company’s Consolidated Statements of Income. Changes in the fair value of IRLCs subsequent to inception are based on; (i) changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and (ii) changes in the probability when the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time. Customer loan derivatives The Company enters into customer loan derivatives to facilitate the risk management strategies for commercial banking customers. The Company mitigates this risk by entering into equal and offsetting loan swap agreements with highly rated third-party financial institutions. The loan swap agreements are free-standing derivatives and are recorded at fair value in the Company's consolidated balance sheet. The Company is party to master netting arrangements with its financial institutional counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all loan swap agreements, as well as collateral or cash funds, in the event of default on, or termination of, any one contract. Collateral is provided by cash or securities received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. Currently, the Company has posted cash of $650 thousand with counterparties.

Commitments and Contingencies Disclosure [Abstract]
OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES	OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES Customer Obligations The Company is a party to financial instruments in the normal course of business to meet financing needs of its customers. These financial instruments include commitments to extend credit, unused or unadvanced loan funds, and letters of credit. The Company uses the same lending policies and procedures to make such commitments as it uses for other lending products. Customer’s creditworthiness is evaluated on a case-by-case basis. Commitments to originate loans, including unused or unadvanced loan funds, are agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require customer payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Standby letters of credit generally become payable upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and a third party. The contractual amount of these letters of credit represents the maximum potential future payments guaranteed by the Company. Typically these letters of credit expire if unused; therefore the total amounts do not necessarily represent future cash requirements. The following table summarizes the contractual amounts of commitments and contingent liabilities to customers as of December 31, 2018 and December 31, 2017 : (in thousands) 2018 2017 Commitments to originate new loans $ 20,431 $ 52,438 Unused funds on commercial and other lines of credit 169,063 134,408 Unadvanced funds on home equity lines of credit 106,121 108,745 Unadvanced funds on construction and real estate loans 133,130 87,915 Commercial letters of credit 1,171 928 Standby letters of credit 486 486 Total $ 430,402 $ 384,920 Operating Lease Obligations The Company leases certain properties used in operations under terms of operating leases, which include renewal options. The following table sets forth the approximate future lease payments over the remaining terms of the non-cancelable leases as of December 31, 2018 .

Legal Claims Various legal claims arise from time to time in the normal course of business. As of December 31, 2018 , neither the Company nor its subsidiaries were involved in any pending legal proceedings believed by management to be material to the Company’s financial condition or results of operations. Periodically, there have been various claims and lawsuits involving the Company, such as claims to enforce liens, condemnation proceedings on properties in which the Company holds security interests, claims involving the making and servicing of real property loans, and other issues incident in the normal course of the Company's business. However, neither the Company nor its subsidiaries are a party to any pending legal proceedings that it believes, in the aggregate, would have a material adverse effect on the financial condition or operations of the Company. Additionally, an estimate of future, probable losses cannot be estimated as of December 31, 2018 .

SHAREHOLDERS’ EQUITY AND EARNINGS PER COMMON SHARE	SHAREHOLDERS’ EQUITY AND EARNINGS PER COMMON SHARE The actual and required capital ratios at December 31, 2018 and December 31, 2017 were as follows: 2018 Actual Minimum Capital Requirement Minimum to be Well-Capitalized Under Prompt Corrective Action Provisions (in thousands, except ratios) Amount Ratio Amount Ratio Amount Ratio Company (consolidated) Total capital to risk-weighted assets $ 331,628 14.23 % $ 186,405 8.00 % $ 244,656 10.00 % Common equity tier 1 capital to risk-weighted assets 274,838 11.80 104,853 4.50 151,454 6.50 Tier 1 capital to risk-weighted assets 295,458 12.68 139,803 6.00 186,404 8.00 Tier 1 capital to average assets 295,458 8.53 138,482 4.00 173,102 5.00 Bank Total capital to risk-weighted assets $ 321,390 13.82 % $ 186,092 8.00 % $ 244,246 10.00 % Common equity tier 1 capital to risk-weighted assets 302,220 12.99 104,677 4.50 151,200 6.50 Tier 1 capital to risk-weighted assets 302,220 12.99 139,569 6.00 186,092 8.00 Tier 1 capital to average assets 302,220 8.74 138,392 4.00 172,990 5.00 2017 Actual Minimum Capital Requirement Minimum to be Well-Capitalized Under Prompt Corrective Action Provisions (in thousands, except ratios) Amount Ratio Amount Ratio Amount Ratio Company (consolidated) Total capital to risk-weighted assets $ 307,305 13.73 % $ 179,047 8.00 % $ 234,999 10.50 % Common equity tier 1 capital to risk-weighted assets 252,096 11.26 100,714 4.50 145,476 6.50 Tier 1 capital to risk-weighted assets 272,716 12.19 134,286 6.00 179,047 8.00 Tier 1 capital to average assets 272,716 8.10 134,758 4.00 168,447 5.00 Bank Total capital to risk-weighted assets $ 306,495 13.71 % $ 178,868 8.00 % $ 234,764 10.50 % Common equity tier 1 capital to risk-weighted assets 288,906 12.92 100,613 4.50 145,331 6.50 Tier 1 capital to risk-weighted assets 288,906 12.92 134,151 6.00 178,868 8.00 Tier 1 capital to average assets 288,906 8.58 134,702 4.00 168,378 5.00 At each date shown, the Company and the Bank met the conditions to be classified as “well capitalized” under the relevant regulatory framework. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table above. Effective January 1, 2015, the Company and the Bank became subject to the Basel III rule that requires the Company and the Bank to assess their Common equity tier 1 capital to risk weighted assets and the Company and the Bank each exceed the minimum to be well capitalized. In addition, the final capital rules added a requirement to maintain a minimum conservation buffer, composed of common equity tier 1 capital, of 2.5% of risk weighted assets, to be phased-in over three years and applied to the common equity tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio and the Total risk-based capital ratio. Accordingly, banking organizations, on a fully phased in basis no later than January 1, 2019, must maintain a minimum Common equity tier 1 risk-based capital ratio of 7.0% , a minimum Tier 1 risk-based capital ratio of 8.5% and a minimum Total risk-based capital ratio of 10.5% . The required minimum conservation buffer began to be phased-in incrementally, starting at 0.625% on January 1, 2016 and increasing to 1.25% on January 1, 2017. The buffer increased to 1.875% on January 1, 2018 and will increase to 2.5% on January 1, 2019. The final capital rules impose restrictions on capital distributions and certain discretionary cash bonus payments if the minimum capital conservation buffer is not met. At December 31, 2018 , the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered well-capitalized for regulatory purposes. The capital levels of both the Company and the Bank at December 31, 2018 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 0.625% .

STOCK-BASED COMPENSATION PLANS	STOCK BASED COMPENSATION PLANS On October 3, 2000, the shareholders of the Company approved the Bar Harbor Bankshares and Subsidiaries Incentive Stock Option Plan of 2000 (the “ISOP”) for its officers and employees, which provided for the issuance of up to 1,012,500 shares of common stock. The purchase price of the stock covered by each option must be at least 100% of the trading value on the date such option was granted. Vesting terms ranged from three to seven years. According to the ISOP no option shall be granted after October 3, 2010, ten years after the effective date of the ISOP. On May 19, 2009, the shareholders of the Company approved the adoption of the 2009 Bar Harbor Bankshares and Subsidiaries Equity Incentive Plan (the “2009 Plan”) for employees and directors of the Company and its subsidiaries. Subject to adjustment for stock splits, stock dividends, and similar events, the total number of shares of common stock that can be issued under the 2009 Plan over the 10 year period in which the plan will be in place is 393,750 shares of common stock, provided that no more than 168,750 shares of such stock can be awarded in the form of restricted stock or restricted stock units, as further described in the 2009 Plan. The 2009 Plan is administered by the Company’s Compensation Committee. All employees and directors of the Company and its subsidiaries are eligible to participate in the 2009 Plan, subject to the discretion of the administrator and the terms of the 2009 Plan. The maximum stock award granted to one individual may not exceed 45,000 shares of common stock (subject to adjustment for stock splits, and similar events) for any calendar year. No grants were made after May 18, 2015 pursuant to this plan. On May 19, 2015, the shareholders of the Company approved the adoption of the 2015 Bar Harbor Bankshares and Subsidiaries Equity Incentive Plan (the “2015 Plan”) for employees and directors of the Company and its subsidiaries. Subject to adjustment for stock splits, stock dividends, and similar events, the total number of shares of common stock that can be issued under the 2015 Plan over the 10 year period in which the plan will be in place is 420,000 shares of common stock. The 2015 Plan is administered by the Company’s Compensation Committee.

According to the 2015 Plan no shares shall be granted after May 19, 2019. As of December 31, 2018 , there were 117,134 shares available for grant under this plan. In April of 2013, the Board of Directors approved a Long Term Incentive Program for senior management members. The program is designed to be made up of a series of three year rolling plans utilizing the shares made available through the approved equity plans. Grants may be given in time vested restricted stock awards, time vested restricted stock units or performance vested restricted stock units, or a combination of these types of grants. Compensation expense recognized in connection with the stock based compensation plans are presented in the following table for the years ended December 31, 2018 , 2017 , and 2016 : (in thousands) 2018 2017 2016 Stock options and restricted stock awards $ 350 $ 399 $ 543 Performance stock units 237 290 304 Restricted stock units 711 585 431 Total compensation expense $ 1,298 $ 1,274 $ 1,278 The total tax benefit recognized associated with stock options and restricted stock awards for the years ended 2018 , 2017 and 2016 was $ 81 thousand, $308 thousand and $274 thousand , respectively.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value. Recurring Fair Value Measurements The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of December 31, 2018 and December 31, 2017 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value. December 31, 2018 (in thousands) Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value Available for sale securities: Mortgage-backed securities: US Government-sponsored enterprises $ — $ 404,952 $ — $ 404,952 US Government agency — 110,512 — 110,512 Private label — 20,382 — 20,382 Obligations of states and political subdivisions thereof — 132,265 — 132,265 Corporate bonds — 57,726 — 57,726 Derivative assets — 2,156 8 2,164 Derivative liabilities — (1,353 ) — (1,353 ) December 31, 2017 (in thousands) Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value Available for sale securities: Obligations of US Government sponsored enterprises $ — $ 6,972 $ — $ 6,972 Mortgage-backed securities: US Government-sponsored enterprises — 443,003 — 443,003 US Government agency — 95,596 — 95,596 Private label — 674 — 674 Obligations of states and political subdivisions thereof — 140,200 — 140,200 Corporate bonds — 30,797 — 30,797 Derivative assets — 669 — 669 Derivative liabilities — (222 ) (222 ) Securities Available for Sale: All securities and major categories of securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from independent pricing providers. The fair value measurements used by the pricing providers consider observable data that may include dealer quotes, market maker quotes and live trading systems. If quoted prices are not readily available, fair values are determined using matrix pricing models, or other model-based valuation techniques requiring observable inputs other than quoted prices such as market pricing spreads, credit information, callable features, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, default rates, and the securities’ terms and conditions, among other things. Derivative Assets and Liabilities Interest Rate Lock Commitments. The Company enters into IRLCs for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan in a lock position will ultimately close. The closing ratio is derived from the Bank’s internal data and is adjusted using significant management judgment. As such, IRLCs are classified as Level 3 measurements. Forward Sale Commitments . The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the IRLCs and loans originated for sale. The fair values of the Company’s mandatory delivery loan sale commitments are determined similarly to the IRLCs using quoted prices in the market place that are observable. However, closing ratios included in the calculation are internally generated and are based on management’s judgment and prior experience, which are considered factors that are not observable. As such, mandatory delivery forward commitments are classified as Level 3 measurements. Customer Loan Derivatives. The valuation of the Company’s customer loan derivatives is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of non-performance risk, the Company has considered the impact of master netting arrangements and any applicable credit enhancements, such as collateral postings. Although the Company has determined that the majority of the inputs used to value its customer loan derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2018 , the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. The table below presents the changes in Level 3 assets and liabilities that were measured at fair value on a recurring basis in 2018 and 2017 .

There were no Level 1 or Level 2 non-recurring fair value measurements for the periods ended December 31, 2018 and December 31, 2017 . Impaired Loans. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, non-recurring fair value measurement adjustments that relate to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Capitalized loan servicing rights . A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. Other real estate owned (“OREO”). OREO results from the foreclosure process on residential or commercial loans issued by the Bank. Upon assuming the real estate, the Company records the property at the fair value of the asset less the estimated sales costs. Thereafter, OREO properties are recorded at the lower of cost or fair value less the estimated sales costs. OREO fair values are primarily determined based on Level 3 data including sales comparables and appraisals. Summary of Estimated Fair Values of Financial Instruments The following table represents estimated fair values, and related carrying amounts of the Company’s financial instruments as of December 31, 2018 and December 31, 2017 . Certain financial instruments and all non-financial instruments are excluded from disclosure requirements.

Cash and cash equivalents. Carrying value is assumed to represent fair value for cash and cash equivalents that have original maturities of ninety days or less. FHLB bank stock and restricted securities. Carrying value approximates fair value based on the redemption provisions of the issuers. Cash surrender value of life insurance policies. Carrying value approximates fair value. Loans, net. As of December 31, 2018 , the fair value of loans were calculated on an individual basis with consideration given to the loans' underlying characteristics, including account types, remaining terms, annual interest rates or coupons, interest types, timing of principal and interest payments, current market rates, risk ratings, credit ratings and remaining balances. A discounted cash flow model is used to estimate the fair value of the loans using assumptions for the coupon rates, remaining maturities, prepayment speeds, liquidity premiums, projected default probabilities, losses given defaults, and estimates of prevailing discount rates. As of December 31, 2017, the fair value of loans was estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. Accrued interest receivable. Carrying value approximates fair value. Deposits. The fair value of demand, non-interest bearing checking, savings and money market deposits is determined as the amount payable on demand at the reporting date. The fair value of time deposits is estimated by discounting the estimated future cash flows using market rates offered for deposits of similar remaining maturities. Borrowed funds. The fair value of borrowed funds is estimated by discounting the future cash flows using market rates for similar borrowings. Such funds include all categories of debt and debentures in the table above. Subordinated borrowings. The Company utilizes a pricing service along with internal models to estimate the valuation of its junior subordinated debentures. The junior subordinated debentures re-price every ninety days. Off-balance-sheet financial instruments. Off-balance-sheet financial instruments include standby letters of credit and other financial guarantees and commitments considered immaterial to the Company’s financial statements.

Revenue from Contract with Customer [Abstract]
Non-Interest Income	NON-INTEREST INCOME Adoption of "ASC 606", Revenue from Contracts with Customers The Company completed its overall assessment of revenue streams and review of related contracts within scope of Accounting Standards Codification ("ASC") 606, including trust and investment management fees, financial services fees, interchange fees, customer deposit fees, and other customer service fees. Based on this assessment, the Company concluded that ASC 606 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross vs. net). Based on its evaluation, the Company determined the classification of certain debit and credit card related costs should change (i.e., costs previously recorded as expense are now recorded as contra-revenue, and vice versa). These classification changes resulted in immaterial changes to both revenue and expense. These changes did not have a material effect to non-interest income or expense. Additionally, the Company reviewed deferred revenue from benefits received under various incentive contracts. The Company noted one contract was significantly impacted by the adoption, which the related financial impact and details are reflected in the tables below. The Company adopted ASC 606 on January 1, 2018, using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the prior guidance of ASC 605 - Revenue Recognition. The adoption effected the Company's accounting for deferred revenue related to an upfront incentive received in connection with a co-branding agreement. The incentive, which was previously amortized over the life of the contract is now constrained by a termination penalty based on future customer transaction volume. As a result, the remaining deferred liability was re-established to its original value, which increased deferred tax assets by $57 thousand and reduced retained earnings by $184 thousand . Operating results during 2018 were not effected. Financial Statement Impact The cumulative effect of the changes made to the consolidated January 1, 2018 balance sheet for the adoption were as follows: (in thousands) Balance at December 31, 2017 Adjustments due to Topic 606 Balance at January 1, 2018 Balance Sheet Other Assets $ 24,389 $ 57 $ 24,446 Other Liabilities 28,737 241 28,978 Retained Earnings 144,977 (184 ) 144,793 Transaction Price Allocated to Future Performance Obligations ASC 606 requires the Company to disclose the aggregate amount of transaction price allocated to performance obligations that have not yet been satisfied as of January 1, 2018. The guidance provides certain practical expedients which limit this requirement and, therefore, the Company does not disclose the value of unsatisfied performance obligations for: (1) contracts with an original expected length of one year or less; (2) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed; or (3) variable consideration allocated entirely to a wholly unsatisfied performance obligation for which consideration is allocated in accordance with paragraph 606-10-32-40. All revenue accounted for under the scope of ASC 606 meets one of these three criteria. Disaggregation of Revenue The following tables disaggregates the Company’s revenue by major business line and timing of transfer of products or services: (in thousands) Twelve Months Ended December 31, 2018 Major Products/Service Lines Trust management fees $ 11,017 Financial services fees 968 Interchange fees 4,434 Customer deposit fees 3,800 Other customer service fees 1,304 Total $ 21,523 (in thousands) Twelve Months Ended December 31, 2018 Timing of Revenue Recognition Products and services transferred at a point in time $ 9,766 Products and services transferred over time 11,757 Total $ 21,523 Trust Management Fees The trust management business generates revenue through a range of fiduciary services including trust and estate administration, wealth advisory, and investment management to individuals, businesses, not-for-profit organizations, and municipalities. Revenue from these services are generally recognized over time and is typically based on a time elapsed measure of progress. Certain fees, such as bill paying fees, distribution fees, real estate sale fees, and supplemental tax service fees, are recorded as revenue at a point in time upon the completion of the service. Financial Services Fees Bar Harbor Financial Services is a branch office of Infinex, an independent registered broker dealer offering securities and insurance products not affiliated with the Company or its subsidiaries. The Company has a revenue sharing agreement with Infinex for any financial service fee income generated. Financial services fees are recognized at a point in time upon the completion of monthly service requirements. Interchange Fees The Company earns interchange fees from transaction fees that merchants pay whenever a customer uses a debit card to make a purchase from the merchant. The fees are paid to the card-issuing bank to cover handling costs, fraud, bad debt costs and the risk involved in approving the payment. Interchange fees are generally recognized as revenue at a point in time upon the completion of a debit card transaction. Customer Deposit Fees The Customer Deposit business offers a variety of deposit accounts with a range of interest rates, fee schedules and other terms, which are designed to meet the customer's financial needs. Additional depositor related services provided to customers include ATM, bank-by-phone, internet banking, internet bill pay, mobile banking, and other cash management services which include remote deposit capture, ACH origination, and wire transfers. These customer deposit fees are generally recognized by the Company at a point in time upon the completion of the service. Other Customer Service Fees The Company has certain incentive and referral fee arrangements with independent third parties in which fees are earned for new account activity, product sales, or transaction volume generated for the respective third parties. The Company also earns a percentage of the fees generated from third party credit card plans promoted through the Bank. Revenue from these incentive and referral fee arrangements are recognized over time using the right to invoice measure of progress. Contract Balances with Customers The following table provides information about receivables, contract assets, and deferred revenues from contracts with customers. (in thousands) Balance at December 31, 2018 Balance at December 31, 2017 Other Assets $ 2,866 $ 972 Other Liabilities 4,923 342 The timing of revenue recognition, billings and cash collections results in receivables, contract assets and contract liabilities on the Consolidated Balance Sheets. For most customer contracts, fees are deducted directly from customer accounts and, therefore, there is no associated impact on the accounts receivable balance. For certain types of service contracts, the Company has an unconditional right to consideration under the service contract and an accounts receivable balance is recorded for services completed. When consideration is received, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract, a contract liability is recorded. Contract liabilities are recognized as revenue after control of the products or services is transferred to the customer and all revenue recognition criteria have been met. Costs to Obtain and Fulfill a Contract The Company currently expenses contract costs for processing and administrative fees for debit card transactions. The Company also expenses custody fees and transactional costs associated with securities transactions as well as third party tax preparation fees. The Company has elected the practical expedient in ASC 340-40-25-4, whereby the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets the Company otherwise would have recognized is one year or less.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation: The consolidated financial statements (the “financial statements”) of Bar Harbor Bankshares and its subsidiaries (the “Company” or “Bar Harbor”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Bar Harbor Bankshares is a Maine Financial Institution Holding Company for the purposes of the laws of the state of Maine, and as such, is subject to the jurisdiction of the Superintendent of the Maine Bureau of Financial Institutions. These financial statements include the accounts of the Company, its wholly-owned subsidiary Bar Harbor Bank & Trust (the "Bank") and the Bank’s consolidated subsidiaries. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless U.S. GAAP requires otherwise.
Consolidation	Consolidation: The accompanying consolidated financial statements have been prepared in accordance with GAAP. The consolidated financial statements include the accounts of Bar Harbor Bankshares and its wholly-owned subsidiary, Bar Harbor Bank & Trust. All significant inter-company balances and transactions have been eliminated in consolidation. Assets held in a fiduciary capacity are not assets of the Company, but assets of customers, and therefore, are not included in the consolidated balance sheets.
Reclassifications	Reclassifications: Whenever necessary, amounts in the prior years’ financial statements are reclassified to conform to current presentation. The reclassifications had no impact on net income in the Company’s consolidated income statement.
Stock Split	Stock Split: On February 21, 2017, the Company's Board of Directors declared a three-for-two stock split payable on March 21, 2017 as a large stock dividend. Shares presented in prior years have been adjusted to conform to the same basis.
Use of estimates	Use of estimates: In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to change in the near term relate to the determination of the allowance for loan losses, other-than-temporary impairment on securities, income tax estimates, reviews of goodwill for impairment, and accounting for post-retirement plans.
Cash and Cash Equivalents	Cash and Cash Equivalents: For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, Federal Funds sold, and other short-term investments with maturities less than 90 days. The Federal Reserve Bank requires the Bank to maintain certain reserve requirements of vault cash and/or deposits.
Investment Securities and Other-Than-Temporary Impairments on Investment Securities	Investment Securities: All securities held at December 31, 2018 and 2017 were classified as available-for-sale (“AFS”). Available for sale securities primarily consist of mortgage-backed securities and obligations of state and political subdivisions there of, and are carried at estimated fair value. Changes in estimated fair value of AFS securities, net of applicable income taxes, are reported in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity unless deemed to be other-than-temporarily impaired (“OTTI”) as discussed below. The Company does not have any securities classified as trading or held-to-maturity. Premiums and discounts on securities are amortized and accreted over the term of the securities using the interest method. Gains and losses on the sale of securities are recognized at the trade date using the specific-identification method and are shown separately in the Consolidated Statements of Income. Other-Than-Temporary Impairments on Investment Securities: The Company conducts an OTTI analysis of investment securities on a quarterly basis or more often if a potential loss-triggering event occurs. A write-down of a debt security is recorded when fair value is below amortized cost in circumstances where: (1) the Company has the intent to sell a security; (2) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. If the Company intends to sell a security or if it is more likely than not that the Company will be required to sell the security before recovery, an OTTI write-down is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value. If the Company does not intend to sell the security or it is not more likely than not that it will be required to sell the security before recovery, the OTTI write-down is separated into an amount representing credit loss, which is recognized in earnings, and an amount related to all other factors, which is recognized in other comprehensive income. To determine the amount related to credit loss on a debt security, the Company applies a methodology similar to that used for evaluating the impairment of loans.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock: The Bank is a member of the Federal Home Loan Bank of Boston (“FHLB”). The Bank uses the FHLB for most of its wholesale funding needs. As a requirement of membership in the FHLB, the Bank must own a minimum required amount of FHLB stock, calculated periodically based primarily on its level of borrowings from the FHLB. FHLB stock is a non-marketable equity security and therefore is reported at cost, which generally equals par value. Shares held in excess of the minimum required amount are generally redeemable at par value. The Company periodically evaluates its investment in FHLB stock for impairment based on, among other things, the capital adequacy of the FHLB and its overall financial condition. Based on the capital adequacy, liquidity position and sustained profitability of the FHLB, management believes there is no impairment related to the carrying amount of the Bank’s FHLB stock as of December 31, 2018 .
Loans Held for Sale	Loans Held for Sale: Loans originated with the intent to be sold in the secondary market are accounted for at the lower of cost or market (fair value). Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in non-interest income. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in non-interest income or non-interest expense as earned or incurred.
Loans	Loans: Loans are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest on loans is accrued and credited to income based on the principal amount of loans outstanding. Loan origination and commitment fees and direct loan origination costs are deferred, and the net amount is amortized as an adjustment of the related loans’ yield, using the level-yield method over the estimated lives of the related loans. Acquired Loans: Loans acquired in acquisitions are initially recorded at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest. For loans that meet the criteria stipulated in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality,” the Company recognizes the accretable yield, which is defined as the excess of all cash flows expected at acquisition over the initial fair value of the loan, as interest income on a level-yield basis over the expected remaining life of the loan. The excess of the loan’s contractually required payments over the cash flows expected to be collected is the non-accretable difference. The non-accretable difference is not recognized as an adjustment of yield, a loss accrual, or a valuation allowance. The Company evaluates quarterly whether the timing and cash to be collected are reasonably expected. Subsequent significant increases in cash flows the Company expects to collect will first reduce any previously recognized valuation allowance and then be reflected prospectively as an increase to the level yield. Subsequent decreases in expected cash flows may result in the loan being considered impaired. Interest income is not recognized to the extent that the net investment in the loan would increase to an amount greater than the estimated payoff amount. For loans that do not meet the ASC 310-30 criteria, the Company accretes interest income based on the contractually required cash flows. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450, “Contingencies” by collectively evaluating these loans for an allowance for loan loss. Acquired loans that met the criteria for non-accrual of interest prior to the acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be non-accrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield.
Non-performing loans	Non-performing loans: Residential real estate and home equity loans are generally placed on non-accrual status when reaching 90 days past due, or in process of foreclosure, or sooner if considered appropriate by management. Consumer loans are generally placed on non-accrual when reaching 90 days or more past due, or sooner if considered appropriate by management. Secured consumer loans are written down to net realizable value and unsecured consumer loans are charged-off upon reaching 120 days past due. Commercial real estate loans and commercial business loans that are 90 days or more past due are generally placed on non-accrual status, unless secured by sufficient cash or other assets immediately convertible to cash, and the loan is in the process of collection. Commercial real estate and commercial business loans may be placed on non-accrual status prior to the 90 days delinquency date if considered appropriate by management. When a loan has been placed on non-accrual status, previously accrued and uncollected interest is reversed against interest on the loan. The interest on non-accrual loans is accounted for using the cash-basis or cost-recovery method depending on corresponding credit risk, until qualifying for return to accrual status. A loan can be returned to accrual status when collectability of principal is reasonably assured and the loan has performed for a period of time, generally six months.
Impaired loans	Impaired loans: A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect all amounts due from the borrower in accordance with the contractual terms of the loan, including scheduled interest payments. Factors considered by management in determining impairment include payment status and collateral value. In considering loans for evaluation of impairment, management generally excludes smaller balance, homogeneous loans; residential mortgage loans, home equity loans, and all consumer loans, unless such loans were restructured in a troubled debt restructuring. These loans are collectively evaluated for risk of loss. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs, and unamortized premiums or discounts), impairment is recognized by establishing or adjusting an existing allocation of the allowance for loan losses, or by recording a partial charge-off of the loan to its fair value. Interest payments made on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case, interest income may be accrued or recognized on a cash basis.
Loans Modified in a Troubled Debt Restructuring	Loans Modified in a Troubled Debt Restructuring: Loans are considered to have been modified in a troubled debt restructuring when, due to a borrower’s financial difficulties, the Company makes certain concessions to the borrower that it would not otherwise consider. Modifications may include interest rate reductions, principal or interest forgiveness, forbearance, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral. Generally, a non-accrual loan that has been modified in a troubled debt restructuring remains on non-accrual status for a period of at least 6 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 non-accrual status.
Allowance for Loan Losses	Allowance for Loan Losses: The allowance for loan losses (the “allowance”) is a significant accounting estimate used in the preparation of the Company’s consolidated financial statements. The allowance is available to absorb losses inherent in the current loan portfolio and is maintained at a level that, in management’s judgment, is appropriate for the amount of risk inherent in the loan portfolio, given past and present conditions. The allowance is increased by provisions charged to operating expense and by recoveries on loans previously charged off, and is decreased by loans charged off as uncollectible. The allowance is calculated in accordance with ASC 310 - Receivables and ASC 450 - Contingencies. Under the guidance of ASC 310, specific allowances are established in cases where management has identified significant conditions or circumstances related to individual loans where the probability of a loss may be incurred. Credit loss estimates for loans without specific allowances are determined under the guidance of ASC 450, which includes portfolio segmentation based on similar risk characteristics, determination of estimated historical loss rates, calculation of a time-based loss emergence and confirmation periods, and adjustments for certain qualitative risk factors. Arriving at an appropriate level of allowance for loan losses involves a high degree of judgment. The determination of the adequacy of the allowance and provisioning for estimated losses is evaluated regularly based on review of loans, with particular emphasis on non-performing and other loans that management believes warrant special consideration. While management uses available information to recognize losses on loans, changing economic conditions and the economic prospects of the borrowers may necessitate future additions or reductions to the allowance. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance, which also may necessitate future additions or reductions to the allowance, based on information available to them at the time of their examination. Refer to Note 4 - Allowance for Loan Losses , for further information, including the Company’s loan loss estimation methodology.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments: The unfunded reserve is a component of other liabilities and represents the estimate for probable credit losses inherent in unfunded commitments to extend credit. Unfunded commitments to extend credit include banker’s acceptances, and standby and commercial letters of credit. The process used to determine the unfunded reserve is consistent with the process for determining the allowance, as adjusted for estimated funding probabilities or loan and lease equivalency factors. The level of the unfunded reserve is adjusted by recording on an expense or recovery in other noninterest expense. Reserve for unfunded commitments are classified in other liabilities on the Company’s Consolidated Balance Sheet.
Premises and Equipment	Premises and Equipment: Premises and equipment and related improvements are stated at cost less accumulated depreciation. Depreciation is computed on the straight-line method over the lesser of the lease term or estimated useful lives of related assets; generally 25 to 39 years for premises and three to seven years for furniture and equipment. Software costs are stated at cost less accumulated depreciation within other assets on the Consolidated Statements of Condition. Amortization expense is calculated using the straight-line method over the estimated useful lives of the related assets.
Goodwill and Identifiable Intangible Assets	Goodwill and Identifiable Intangible Assets: In connection with acquisitions, the Company generally records as assets on its consolidated financial statements both goodwill and identifiable intangible assets, such as core deposit intangibles. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in accordance with the purchase method of accounting for business combinations. Goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis, or more frequently, if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. The impairment testing process is conducted by assigning assets and goodwill to each reporting unit. Currently, the Company’s goodwill is evaluated at the entity level as there is only one reporting unit. The Company first assesses certain qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying value. If it is more likely than not that the fair value of the reporting unit is less than the carrying value, then the fair value of each reporting unit is compared to the recorded book value “step one.” If the fair value of the reporting unit exceeds its carrying value, goodwill is not considered impaired and “step two” is not considered necessary. If the carrying value of a reporting unit exceeds its fair value, the impairment test continues (“step two”) by comparing the carrying value of the reporting unit’s goodwill to the implied fair value of goodwill. The implied fair value is computed by adjusting all assets and liabilities of the reporting unit to current fair value with the offset adjustment to goodwill. The adjusted goodwill balance is the implied fair value of the goodwill. An impairment charge is recognized if the carrying fair value of goodwill exceeds the implied fair value of goodwill. Identifiable intangible assets, included in other assets on the consolidated balance sheet, consist of core deposit intangibles amortized over their estimated useful lives on a straight-line method, which approximates the economic benefits to the Company. These assets are reviewed for impairment at least annually, or whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The determination of which intangible assets have finite lives is subjective, as is the determination of the amortization period for such intangible assets. Any negative changes in the estimates used by the Company to determine the carrying value of its goodwill and identifiable intangible assets, or which otherwise adversely affect their value or estimated lives, would adversely affect the Company’s consolidated results of operations.
Bank-Owned Life Insurance	Bank-Owned Life Insurance: Bank-owned life insurance (“BOLI”) represents life insurance on the lives of certain current and retired employees who had provided positive consent allowing the Bank to be the beneficiary of such policies. Increases in the cash value of the policies, as well as insurance proceeds received in excess of the cash value, are recorded in other non-interest income, and are not subject to income taxes. The cash surrender value is included in other assets on the Company’s consolidated balance sheet.
Other Real Estate Owned	Other Real Estate Owned: Other real estate owned consists of properties acquired through foreclosure proceedings or acceptance of a deed-in-lieu of foreclosure. These properties are recorded at fair value less estimated costs to sell the property. If the recorded investment in the loan exceeds the property’s fair value at the time of acquisition, a charge-off is recorded against the allowance. If the fair value of the property at the time of acquisition exceeds the carrying amount of the loan, the excess is recorded either as a recovery to the allowance if a charge-off had previously been recorded, or as a gain on initial transfer in other non-interest income. Subsequent decreases in the property’s fair value and operating expenses of the property are recognized through charges to other non-interest expense. The fair value of the property acquired is based on third-party appraisals, broker price opinions, recent sales activity, or a combination thereof, subject to management judgment.
Capitalized Servicing Rights	Capitalized Servicing Right s : Capitalized servicing rights are recognized as assets when mortgage loans are sold and the rights to service those loans are retained. The Company’s capitalized servicing rights are accounted for under the amortization method and are initially recorded at fair value. Fair values are established by using a discounted cash flow model to calculate the present value of estimated future net servicing income. Changes in the fair value of capitalized servicing rights are primarily due to changes in valuation inputs, assumptions, and the collection and realization of expected cash flows. However, these capitalized servicing rights are amortized in proportion to and over the period of estimated net servicing income, which includes prepayment assumptions. An impairment analysis is prepared on a quarterly basis by estimating the fair value of the capitalized servicing rights and comparing that value to the carrying amount. A valuation allowance is established when the carrying amount of these capitalized servicing rights exceeds fair value.
Senior and Subordinated Borrowing Policy	Senior and Subordinated Borrowings: The Company's borrowings include retail and wholesale repurchase agreements, FHLB overnight and short-term borrowings, Federal Funds purchased, line of credit advances and subordinated notes. The Company is required to post collateral for certain borrowings, for which it, generally, posts loans and/or investment securities as collateral.
Derivative Financial Instruments	Derivative Financial Instruments: The Company recognizes all derivative instruments on the consolidated balance sheet at fair value. On the date the derivative instrument is entered into, the Company designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives used in hedging transactions are highly effective in offsetting the changes in cash flows or fair values of hedged items. Changes in the fair value of derivative instruments that are highly effective and qualify as cash flow hedge are recorded in other comprehensive income/(loss). Any ineffective portion is recorded in earnings. For fair value hedges that are highly effective, the gain or loss on the derivative and the loss or gain on the hedged item attributable to the hedged risk are both recognized in earnings, with the differences (if any) representing hedge ineffectiveness. The Company discontinues hedge accounting when it is determined that the derivative is no longer highly effective in offsetting changes of the hedged risk on the hedged item, or management determines that the designation of the derivative as a hedging instrument is no longer appropriate.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments: In the ordinary course of business, the Company has entered into off-balance sheet financial instruments consisting of commitments to extend credit, unused or unadvanced loan funds and letters of credit. Such financial instruments are recorded in the consolidated financial statements when they are funded or related fees are incurred or received.
Stock Based Compensation	Stock Based Compensation: The Company has equity award plans that include stock option, restricted stock and performance stock, which are described more fully in Note 14 - Stock Based Compensation Plans o f the Consolidated Financial Statements. The Company expenses the grant date fair value of equity awards granted. The expense is recognized over the vesting periods of the grants. The Company uses its treasury shares for issuing shares upon option exercises, restricted stock and performance stock vesting.
Accounting for Retirement Benefit Plans	Accounting for Retirement Benefit Plans: The Company has non-qualified supplemental executive retirement agreements with certain retired officers. The agreements provide supplemental retirement benefits payable in installments over a period of years upon retirement or death. The Company recognized the net present value of payments associated with the agreements over the service periods of the participating officers. Interest costs continue to be recognized on the benefit obligations. The Company also has a supplemental executive retirement agreement with a certain current executive officer. This agreement provides a stream of future payments in accordance with individually defined vesting schedules upon retirement, termination, or in the event that the participating executive leaves the Company following a change of control event. The Company recognizes the net present value of payments associated with these agreements over the service periods of the participating executive officers. Upon retirement, interest costs will continue to be recognized on the benefit obligation. The Company recognizes the over-funded or under-funded status of post-retirement benefit plans as a liability on the balance sheet in other liabilities and recognizes changes in that funded status through other comprehensive income/(loss). Gains and losses, prior service costs and credits, and any remaining transition amounts that have not yet been recognized through net periodic benefit costs are recognized in accumulated other comprehensive income/(loss), net of tax effects, until they are amortized as a component of net periodic cost. The measurement date, which is the date at which the benefit obligation and plan assets are measured, is the Company's fiscal year end.
Income Taxes	Income Taxes: The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current available information indicates that it is more likely than not that deferred tax assets will not be realized, a valuation allowance is established. 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.
Earnings Per Share	Earnings Per Share: Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company, such as the Company’s dilutive stock options.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue in accordance with ASC 606, "Revenue from Contracts with Customers." ASC 606 requires the Company to follow a five step process: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the Company satisfies a performance obligation. Revenue recognition under ASC 606 depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for the goods or service. See Note 16 - Non-Interest Income of the Company's Consolidated Financial Statements for additional information on revenue recognition.
Segment Reporting	Segment Reporting: An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and evaluate performance. The Company has determined that its operations are solely in the community banking industry and include traditional community banking services, including lending activities, acceptance of demand, savings and time deposits, business services, investment management, trust and third-party brokerage services. These products and services have similar distribution methods, types of customers and regulatory responsibilities. Accordingly, segment information is not presented in the Consolidated Financial Statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of accounting standards that could have a material impact to the Company’s consolidated financial statements upon adoption: Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 ASU 2014-09, Revenue from Contracts with Customers This ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry topics of the Codification. The core principle of the ASU is an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU may be adopted either retrospectively or on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, upon completion of an analysis to identify all revenue streams within the scope of this accounting guidance. After reviewing the related contracts as prescribed by the five steps within this ASU, one contract resulted in recognition of a $241 thousand liability with a $184 thousand impact to retained earnings net of tax. The remaining changes had no material impact on the consolidated financial statements. See Note 11 for more detail and transitional disclosures. ASU 2015-14, Deferral of the Effective Date ASU 2016-08, Principal versus Agent Considerations ASU 2016-10, Identifying Performance Obligations and Licensing ASU 2016-12, Narrow-Scope Improvements and Practical Expedience ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities This ASU amends ASC Topic 825, Financial Instruments-Overall, and addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Among other minor amendments applicable to the Company, the main provisions require investments in equity securities to be measured at fair value with changes in fair value recognized through net income unless they qualify for a practicability exception (excludes investments accounted for under the equity method of accounting or those that result in consolidation of the investee). Except for disclosure requirements that will be adopted prospectively, the ASU must be adopted on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have any equity securities that would be in scope of this ASU. However, the Company is subject to the exit pricing notion required in fair value disclosures and after calculating the fair value, the Company had no material impact to its consolidated financial statements. ASU-2018-03, Technical Corrections and Improvements to Financial Instruments ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments This ASU amends Topic 230, Statement of Cash Flows, and provides clarification with respect to classification within the statement of cash flows where current guidance is unclear or silent. The ASU should be adopted retrospectively. If it is impractical to apply the guidance retrospectively for an issue, the amendments related to the issue would be applied prospectively. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 (continued) ASU 2017-07, Compensation- Retirement Benefits This ASU amends Topic 715, Retirement Benefits, and provides more prescriptive guidance around the presentation of net period pension and post-retirement benefit cost in the income statement. The amendment requires the service cost component be disaggregated from other components of net periodic benefit cost in the income statement. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-09, Stock Compensation: Scope of Modification Accounting This ASU amends Topic 718, Compensation- Stock Compensation, and clarifies when modification accounting should be applied to changes in terms or conditions of share-based payment awards. The amendments narrow the scope of modification accounting by clarifying that modification accounting should be applied to awards if the change affects the fair value, vesting conditions, or classification of the award. The amendments do not impact current disclosure requirements for modifications, regardless of whether modification accounting is required under the new guidance. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The ASU amends Topic 220, Income Statement-Reporting Comprehensive Income, and is intended to help organizations reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the recently enacted Tax Reform. The guidance allows entities to reclassify stranded tax effects in accumulated other comprehensive income to retained earnings. January 1, 2019 The Company adopted this ASU as of March 31, 2018. The effect of the reclassification resulted in an increase to retained earnings and a decrease to accumulated other comprehensive income of $980 thousand with zero net effect on total stockholders' equity. ASU 2018-05, Income Taxes (Topic 740) SEC Amendments Early adoption is permitted. ASU 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending Circular 202, issued on July 2, 1985, was rescinded by the Office of the Comptroller of the Currency. The circular limited the net deferred tax debits that could be carried on the Company's balance sheet for regulatory purposes to the amount that would be coverable by the net operating loss carrybacks. The language is no longer relevant and has been removed from the guidance. May 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted ASU 2016-02, Leases This ASU creates ASU Topic 842, Leases, and supersedes Topic 840, Leases. The new guidance requires lessees to record a right-of-use asset and a corresponding liability equal to the present value of future rental payments on their balance sheets for all leases with a term greater than one year. There are not significant changes to lessor accounting; however, there are certain improvements made to align lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. This guidance expands both quantitative and qualitative required disclosures. This ASU is required to be adopted on a modified retrospective basis and allows for practical expedients and elections in conjunction with implementation. The Company may elect some of the expedients upon the adoption date, which may be applied prospectively or retrospectively. January 1, 2019 The Company plans to elect the practical expedients, allowing for existing leases to be accounted for consistent with current guidance, with the exception of balance sheet recognition for lessees. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company will use the effective date as the initial date of application. At adoption the Company expects to recognize a right-of-use asset and corresponding lease liability of $9.0 million. This estimate is based, primarily, on the present value of unpaid future minimum lease payments. Additionally, that amount is impacted by assumptions around renewals and/or extensions, and the interest rate used to discount those future lease obligations. Due to the limited size of the Company's leasing portfolio, many other items related to this standard don't apply, or have an immaterial impact on the Company's consolidated financial statements. ASU 2018-11 Practical Expedients to Topic 842, Leases ASU 2018-02 Scope Improvements for Lessors ASU 2016-13, Measurement of Credit Losses on Financial Instruments This ASU amends Topic 326, Financial Instruments- Credit Losses to replace the current incurred loss accounting model with a current expected credit loss approach (CECL) for financial instruments measured at amortized cost and other commitments to extend credit. The amendments require entities to consider all available relevant information when estimating current expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is to reflect the portion of the amortized cost basis that the entity does not expect to collect. The amendments also eliminate the current accounting model for purchased credit impaired loans and debt securities. Additional quantitative and qualitative disclosures are required upon adoption. January 1, 2020 Adoption of this ASU is expected to primarily change how the Company estimates credit losses with the application of the expected credit loss model. In addition, the Company expects the ASU to change the presentation of credit losses for AFS debt securities through an allowance method rather than as a direct write-off. The Company is in the process of evaluating loan loss estimation models to comply with the guidance under this ASU, which may result in a higher credit loss estimate. ASU 2018-19, Codification Improvements to ASU 2016-13 While the CECL model does not apply to available for sale debt securities, the ASU does require entities to record an allowance when recognizing credit losses for available for sale securities, rather than reduce the amortized cost of the securities by direct write-offs. The ASU should be adopted on a modified retrospective basis. Entities that have loans accounted for under ASC 310-30 at the time of adoption should prospectively apply the guidance in this amendment for purchase credit deteriorated assets. Early adoption is permitted in 2019 Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted (continued) ASU 2017-04, Simplifying the Test for Goodwill Impairment This ASU amends Topic 350, Intangibles-Goodwill and Other, and eliminates Step 2 from the goodwill impairment test. January 1, 2020 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities This ASU amends ASC 815, Derivatives and Hedging to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity's risk management activities by better aligning the entity's financial reporting for hedging relationships with those risk management activities and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. ASU 2018-16, Inclusion of Overnight Financing Rate or Overnight Swap Rate as a Benchmark for Hedge Accounting ASU 2018-07, Share Based Payment Accounting This ASU expands the scope of Topic 718, Compensation- Stock Compensation to include share-based payments issued to non-employees for goods or services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity-Based Payments to non-employees. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements as the Company does not participate in these types of arrangements in the normal course of business, except for board director compensation. ASU 2018-13 Changes to Disclosure Requirements Fair Value Measurement, Topic 820 This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. January 1, 2020 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2018-14 Compensation- Disclosure Requirements for Defined Pension Plans Topic 715-20 This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other post-retirement benefit plans. January 1, 2021 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles	The following table provides a brief description of accounting standards that could have a material impact to the Company’s consolidated financial statements upon adoption: Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 ASU 2014-09, Revenue from Contracts with Customers This ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry topics of the Codification.

ASU 2015-14, Deferral of the Effective Date ASU 2016-08, Principal versus Agent Considerations ASU 2016-10, Identifying Performance Obligations and Licensing ASU 2016-12, Narrow-Scope Improvements and Practical Expedience ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities This ASU amends ASC Topic 825, Financial Instruments-Overall, and addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Among other minor amendments applicable to the Company, the main provisions require investments in equity securities to be measured at fair value with changes in fair value recognized through net income unless they qualify for a practicability exception (excludes investments accounted for under the equity method of accounting or those that result in consolidation of the investee). Except for disclosure requirements that will be adopted prospectively, the ASU must be adopted on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have any equity securities that would be in scope of this ASU. However, the Company is subject to the exit pricing notion required in fair value disclosures and after calculating the fair value, the Company had no material impact to its consolidated financial statements. ASU-2018-03, Technical Corrections and Improvements to Financial Instruments ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments This ASU amends Topic 230, Statement of Cash Flows, and provides clarification with respect to classification within the statement of cash flows where current guidance is unclear or silent. The ASU should be adopted retrospectively. If it is impractical to apply the guidance retrospectively for an issue, the amendments related to the issue would be applied prospectively. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 (continued) ASU 2017-07, Compensation- Retirement Benefits This ASU amends Topic 715, Retirement Benefits, and provides more prescriptive guidance around the presentation of net period pension and post-retirement benefit cost in the income statement. The amendment requires the service cost component be disaggregated from other components of net periodic benefit cost in the income statement. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-09, Stock Compensation: Scope of Modification Accounting This ASU amends Topic 718, Compensation- Stock Compensation, and clarifies when modification accounting should be applied to changes in terms or conditions of share-based payment awards. The amendments narrow the scope of modification accounting by clarifying that modification accounting should be applied to awards if the change affects the fair value, vesting conditions, or classification of the award. The amendments do not impact current disclosure requirements for modifications, regardless of whether modification accounting is required under the new guidance. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The ASU amends Topic 220, Income Statement-Reporting Comprehensive Income, and is intended to help organizations reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the recently enacted Tax Reform. The guidance allows entities to reclassify stranded tax effects in accumulated other comprehensive income to retained earnings. January 1, 2019 The Company adopted this ASU as of March 31, 2018. The effect of the reclassification resulted in an increase to retained earnings and a decrease to accumulated other comprehensive income of $980 thousand with zero net effect on total stockholders' equity. ASU 2018-05, Income Taxes (Topic 740) SEC Amendments Early adoption is permitted. ASU 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending Circular 202, issued on July 2, 1985, was rescinded by the Office of the Comptroller of the Currency. The circular limited the net deferred tax debits that could be carried on the Company's balance sheet for regulatory purposes to the amount that would be coverable by the net operating loss carrybacks. The language is no longer relevant and has been removed from the guidance. May 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted ASU 2016-02, Leases This ASU creates ASU Topic 842, Leases, and supersedes Topic 840, Leases. The new guidance requires lessees to record a right-of-use asset and a corresponding liability equal to the present value of future rental payments on their balance sheets for all leases with a term greater than one year. There are not significant changes to lessor accounting; however, there are certain improvements made to align lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. This guidance expands both quantitative and qualitative required disclosures. This ASU is required to be adopted on a modified retrospective basis and allows for practical expedients and elections in conjunction with implementation. The Company may elect some of the expedients upon the adoption date, which may be applied prospectively or retrospectively. January 1, 2019 The Company plans to elect the practical expedients, allowing for existing leases to be accounted for consistent with current guidance, with the exception of balance sheet recognition for lessees. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company will use the effective date as the initial date of application. At adoption the Company expects to recognize a right-of-use asset and corresponding lease liability of $9.0 million. This estimate is based, primarily, on the present value of unpaid future minimum lease payments. Additionally, that amount is impacted by assumptions around renewals and/or extensions, and the interest rate used to discount those future lease obligations. Due to the limited size of the Company's leasing portfolio, many other items related to this standard don't apply, or have an immaterial impact on the Company's consolidated financial statements. ASU 2018-11 Practical Expedients to Topic 842, Leases ASU 2018-02 Scope Improvements for Lessors ASU 2016-13, Measurement of Credit Losses on Financial Instruments This ASU amends Topic 326, Financial Instruments- Credit Losses to replace the current incurred loss accounting model with a current expected credit loss approach (CECL) for financial instruments measured at amortized cost and other commitments to extend credit. The amendments require entities to consider all available relevant information when estimating current expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is to reflect the portion of the amortized cost basis that the entity does not expect to collect. The amendments also eliminate the current accounting model for purchased credit impaired loans and debt securities. Additional quantitative and qualitative disclosures are required upon adoption. January 1, 2020 Adoption of this ASU is expected to primarily change how the Company estimates credit losses with the application of the expected credit loss model. In addition, the Company expects the ASU to change the presentation of credit losses for AFS debt securities through an allowance method rather than as a direct write-off. The Company is in the process of evaluating loan loss estimation models to comply with the guidance under this ASU, which may result in a higher credit loss estimate. ASU 2018-19, Codification Improvements to ASU 2016-13 While the CECL model does not apply to available for sale debt securities, the ASU does require entities to record an allowance when recognizing credit losses for available for sale securities, rather than reduce the amortized cost of the securities by direct write-offs. The ASU should be adopted on a modified retrospective basis. Entities that have loans accounted for under ASC 310-30 at the time of adoption should prospectively apply the guidance in this amendment for purchase credit deteriorated assets. Early adoption is permitted in 2019 Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted (continued) ASU 2017-04, Simplifying the Test for Goodwill Impairment This ASU amends Topic 350, Intangibles-Goodwill and Other, and eliminates Step 2 from the goodwill impairment test. January 1, 2020 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities This ASU amends ASC 815, Derivatives and Hedging to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity's risk management activities by better aligning the entity's financial reporting for hedging relationships with those risk management activities and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. ASU 2018-16, Inclusion of Overnight Financing Rate or Overnight Swap Rate as a Benchmark for Hedge Accounting ASU 2018-07, Share Based Payment Accounting This ASU expands the scope of Topic 718, Compensation- Stock Compensation to include share-based payments issued to non-employees for goods or services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity-Based Payments to non-employees. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements as the Company does not participate in these types of arrangements in the normal course of business, except for board director compensation. ASU 2018-13 Changes to Disclosure Requirements Fair Value Measurement, Topic 820 This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. January 1, 2020 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2018-14 Compensation- Disclosure Requirements for Defined Pension Plans Topic 715-20 This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other post-retirement benefit plans. January 1, 2021 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted. Financial Statement Impact The cumulative effect of the changes made to the consolidated January 1, 2018 balance sheet for the adoption were as follows: (in thousands) Balance at December 31, 2017 Adjustments due to Topic 606 Balance at January 1, 2018 Balance Sheet Other Assets $ 24,389 $ 57 $ 24,446 Other Liabilities 28,737 241 28,978 Retained Earnings 144,977 (184 ) 144,793

Revenue from Contract with Customer [Abstract]
Financial Statement Impact	The following table provides a brief description of accounting standards that could have a material impact to the Company’s consolidated financial statements upon adoption: Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 ASU 2014-09, Revenue from Contracts with Customers This ASU supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the Industry topics of the Codification. The core principle of the ASU is an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU may be adopted either retrospectively or on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, upon completion of an analysis to identify all revenue streams within the scope of this accounting guidance. After reviewing the related contracts as prescribed by the five steps within this ASU, one contract resulted in recognition of a $241 thousand liability with a $184 thousand impact to retained earnings net of tax. The remaining changes had no material impact on the consolidated financial statements. See Note 11 for more detail and transitional disclosures. ASU 2015-14, Deferral of the Effective Date ASU 2016-08, Principal versus Agent Considerations ASU 2016-10, Identifying Performance Obligations and Licensing ASU 2016-12, Narrow-Scope Improvements and Practical Expedience ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ASU 2016-01, Recognition and Measurement of Financial Assets and Liabilities This ASU amends ASC Topic 825, Financial Instruments-Overall, and addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Among other minor amendments applicable to the Company, the main provisions require investments in equity securities to be measured at fair value with changes in fair value recognized through net income unless they qualify for a practicability exception (excludes investments accounted for under the equity method of accounting or those that result in consolidation of the investee). Except for disclosure requirements that will be adopted prospectively, the ASU must be adopted on a modified retrospective basis. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have any equity securities that would be in scope of this ASU. However, the Company is subject to the exit pricing notion required in fair value disclosures and after calculating the fair value, the Company had no material impact to its consolidated financial statements. ASU-2018-03, Technical Corrections and Improvements to Financial Instruments ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments This ASU amends Topic 230, Statement of Cash Flows, and provides clarification with respect to classification within the statement of cash flows where current guidance is unclear or silent. The ASU should be adopted retrospectively. If it is impractical to apply the guidance retrospectively for an issue, the amendments related to the issue would be applied prospectively. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 (continued) ASU 2017-07, Compensation- Retirement Benefits This ASU amends Topic 715, Retirement Benefits, and provides more prescriptive guidance around the presentation of net period pension and post-retirement benefit cost in the income statement. The amendment requires the service cost component be disaggregated from other components of net periodic benefit cost in the income statement. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-09, Stock Compensation: Scope of Modification Accounting This ASU amends Topic 718, Compensation- Stock Compensation, and clarifies when modification accounting should be applied to changes in terms or conditions of share-based payment awards. The amendments narrow the scope of modification accounting by clarifying that modification accounting should be applied to awards if the change affects the fair value, vesting conditions, or classification of the award. The amendments do not impact current disclosure requirements for modifications, regardless of whether modification accounting is required under the new guidance. January 1, 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The ASU amends Topic 220, Income Statement-Reporting Comprehensive Income, and is intended to help organizations reclassify certain stranded income tax effects in accumulated other comprehensive income resulting from the recently enacted Tax Reform. The guidance allows entities to reclassify stranded tax effects in accumulated other comprehensive income to retained earnings. January 1, 2019 The Company adopted this ASU as of March 31, 2018. The effect of the reclassification resulted in an increase to retained earnings and a decrease to accumulated other comprehensive income of $980 thousand with zero net effect on total stockholders' equity. ASU 2018-05, Income Taxes (Topic 740) SEC Amendments Early adoption is permitted. ASU 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending Circular 202, issued on July 2, 1985, was rescinded by the Office of the Comptroller of the Currency. The circular limited the net deferred tax debits that could be carried on the Company's balance sheet for regulatory purposes to the amount that would be coverable by the net operating loss carrybacks. The language is no longer relevant and has been removed from the guidance. May 2018 The Company adopted this ASU as of January 1, 2018, although it did not have a material impact on the Company's consolidated financial statements. Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted ASU 2016-02, Leases This ASU creates ASU Topic 842, Leases, and supersedes Topic 840, Leases. The new guidance requires lessees to record a right-of-use asset and a corresponding liability equal to the present value of future rental payments on their balance sheets for all leases with a term greater than one year. There are not significant changes to lessor accounting; however, there are certain improvements made to align lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. This guidance expands both quantitative and qualitative required disclosures. This ASU is required to be adopted on a modified retrospective basis and allows for practical expedients and elections in conjunction with implementation. The Company may elect some of the expedients upon the adoption date, which may be applied prospectively or retrospectively. January 1, 2019 The Company plans to elect the practical expedients, allowing for existing leases to be accounted for consistent with current guidance, with the exception of balance sheet recognition for lessees. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company will use the effective date as the initial date of application. At adoption the Company expects to recognize a right-of-use asset and corresponding lease liability of $9.0 million. This estimate is based, primarily, on the present value of unpaid future minimum lease payments. Additionally, that amount is impacted by assumptions around renewals and/or extensions, and the interest rate used to discount those future lease obligations. Due to the limited size of the Company's leasing portfolio, many other items related to this standard don't apply, or have an immaterial impact on the Company's consolidated financial statements. ASU 2018-11 Practical Expedients to Topic 842, Leases ASU 2018-02 Scope Improvements for Lessors ASU 2016-13, Measurement of Credit Losses on Financial Instruments This ASU amends Topic 326, Financial Instruments- Credit Losses to replace the current incurred loss accounting model with a current expected credit loss approach (CECL) for financial instruments measured at amortized cost and other commitments to extend credit. The amendments require entities to consider all available relevant information when estimating current expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is to reflect the portion of the amortized cost basis that the entity does not expect to collect. The amendments also eliminate the current accounting model for purchased credit impaired loans and debt securities. Additional quantitative and qualitative disclosures are required upon adoption. January 1, 2020 Adoption of this ASU is expected to primarily change how the Company estimates credit losses with the application of the expected credit loss model. In addition, the Company expects the ASU to change the presentation of credit losses for AFS debt securities through an allowance method rather than as a direct write-off. The Company is in the process of evaluating loan loss estimation models to comply with the guidance under this ASU, which may result in a higher credit loss estimate. ASU 2018-19, Codification Improvements to ASU 2016-13 While the CECL model does not apply to available for sale debt securities, the ASU does require entities to record an allowance when recognizing credit losses for available for sale securities, rather than reduce the amortized cost of the securities by direct write-offs. The ASU should be adopted on a modified retrospective basis. Entities that have loans accounted for under ASC 310-30 at the time of adoption should prospectively apply the guidance in this amendment for purchase credit deteriorated assets. Early adoption is permitted in 2019 Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted (continued) ASU 2017-04, Simplifying the Test for Goodwill Impairment This ASU amends Topic 350, Intangibles-Goodwill and Other, and eliminates Step 2 from the goodwill impairment test. January 1, 2020 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities This ASU amends ASC 815, Derivatives and Hedging to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity's risk management activities by better aligning the entity's financial reporting for hedging relationships with those risk management activities and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. ASU 2018-16, Inclusion of Overnight Financing Rate or Overnight Swap Rate as a Benchmark for Hedge Accounting ASU 2018-07, Share Based Payment Accounting This ASU expands the scope of Topic 718, Compensation- Stock Compensation to include share-based payments issued to non-employees for goods or services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity-Based Payments to non-employees. January 1, 2019 Adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements as the Company does not participate in these types of arrangements in the normal course of business, except for board director compensation. ASU 2018-13 Changes to Disclosure Requirements Fair Value Measurement, Topic 820 This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. January 1, 2020 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted. ASU 2018-14 Compensation- Disclosure Requirements for Defined Pension Plans Topic 715-20 This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other post-retirement benefit plans. January 1, 2021 The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. Early adoption is permitted. Financial Statement Impact The cumulative effect of the changes made to the consolidated January 1, 2018 balance sheet for the adoption were as follows: (in thousands) Balance at December 31, 2017 Adjustments due to Topic 606 Balance at January 1, 2018 Balance Sheet Other Assets $ 24,389 $ 57 $ 24,446 Other Liabilities 28,737 241 28,978 Retained Earnings 144,977 (184 ) 144,793
