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 (“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 GAAP requires otherwise. In addition, these interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and note disclosures for the Company's Annual Report on Form 10-K for the year ended December 31, 2017 previously filed with the Securities and Exchange Commission (the "SEC"). In management's opinion, all adjustments necessary for a fair statement are reflected in the interim periods presented. 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. Tax Cuts and Jobs Act Public law No. 115-97, known as the Tax Cuts and Jobs Act (the "Tax Act"), enacted on December 22, 2017, reduced the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. Also on December 22, 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides guidance on accounting for tax effects of the Tax Act. SAB 118 provides a measurement period of up to one year from the enactment date to complete the accounting. Any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period when such adjustments are determined. Based on the information available and current interpretation of the rules, the Company estimated the impact of the reduction in the corporate tax rate and remeasurement of certain deferred tax assets and liabilities. The provisional amount recorded in the fourth quarter of 2017 related to the remeasurement of the Company's deferred tax balance resulted in additional income tax expense of $4.0 million . The final impact of the Tax Act may differ from these estimates as a result of changes in management's interpretations and assumptions, as well as new guidance issued by the Internal Revenue Service. Recent Accounting Pronouncements The following table provides a brief description of recent accounting standards updates (ASU") 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 $241,000 liability with a $184,000 impact to retained earnings net of tax. The remaining changes had no material impact on the consolidated financial statements. See below 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 notion pricing 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements. 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 postretirement 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Early adoption is permitted. Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 (continued) 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 adoption of this ASU 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 $980,000 with zero net effect on total stockholders' equity. ASU 2018-05, Income Taxes (Topic 740) SEC Amendments Early adoption is permitted. 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 should be adopted on a modified retrospective basis. January 1, 2019 The Company is currently evaluating its operating lease arrangement under this ASU. Early indications suggest the Company will need to recognize right-of-use assets and lease liabilities for most of its operating lease commitments. ASU 2018-01, Leases (Topic 842) Land Easement Practical Expedient for Transition to Topic 842 Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted (continued) 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. 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 AFS 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. 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. TRANSITIONAL DISCLOSURES FOR RECENTLY ADOPTED ACCOUNTING PROUNOUNCEMENTS Adoption of "ASC 606", Revenue from Contracts with Customers The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the adoption, 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 Accounting Standards Codification ("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 is 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. For contracts that were modified before the effective date, the Company reflected the aggregate effect of all modifications when identifying performance obligations and allocating transaction price in accordance with practical expedient in paragraph ASC 606-10-65-1-(f)-(3), which did not have a material effect on the cumulative impact of adopting ASC 606. The reported results for 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605). 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 the first quarter were not effected. Financial Statement Impact The cumulative effect of the changes made to our 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 The impact of the adoption on our consolidated March 31, 2018 balance sheet was as follows: (in thousands) As Reported Balances Without Adoption of ASC 606 Effect of Change Higher / (Lower) Balance Sheet Other Assets $ 29,793 $ 29,736 $ 57 Other Liabilities 32,214 28,694 254 Retained Earnings 150,701 150,885 (184 ) Disaggregation of Revenue The following table disaggregates the Company’s revenue by major business line and timing of transfer of products or services: Three Months Ended March 31, (in thousands) 2018 Major Products/Service Lines Trust management fees $ 2,741 Financial services fees 221 Interchange fees 1,024 Customer deposit fees 979 Other customer service fees 221 Total $ 5,186 Three Months Ended March 31, (in thousands) 2018 Timing of Revenue Recognition Products and services transferred at a point in time $ 2,351 Products and services transferred over time 2,835 Total $ 5,186 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 their store. 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. 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 March 31, 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. Contract Balances from Contracts with Customers The following table provides information about receivables, contract assets, and contract liabilities from contracts with customers. (in thousands) Balance at March 31, 2018 Balance at December 31, 2017 Balances from contracts with customers only: Other Assets $ 4,175 $ 972 Other Liabilities 3,774 342 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. Due to the period being less than one year, the Company will apply the practical expedient in paragraph 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.

For the three months ended March 31, 2018 and 2017 the Company did not record any other-than-temporary impairment (“OTTI”) losses. Three Months Ended March 31, 2018 2017 Estimated credit losses as of prior year end $ 1,697 $ 1,697 Reductions for securities paid off during the period — — Estimated credit losses at end of the period $ 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. 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 March 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 for the debt securities in an unrealized loss position within the Company’s AFS were not other-than-temporarily impaired at March 31, 2018 : Obligations of US Government-sponsored enterprises At March 31, 2018 , 1 out of the total 2 securities in the Company’s portfolios of AFS US Government sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 0.1% of the amortized cost of securities in unrealized loss positions.The Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“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 quarter. All securities are performing. US Government-sponsored enterprises At March 31, 2018 , 455 out of the total 781 securities in the Company’s portfolios of AFS US Government sponsored enterprises were in unrealized loss positions. Aggregate unrealized losses represented 2.8% 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 quarter. All securities are performing. US Government agency At March 31, 2018 , 117 out of the total 203 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 investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing. Private label At March 31, 2018 , 6 of the total 26 securities in the Company’s portfolio of AFS private-label mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 7.9% 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 At March 31, 2018 , 122 of the total 262 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 3.0% 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 feels the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for the risk. There were no material underlying credit downgrades during the quarter. All securities are performing. Corporate bonds At March 31, 2018 , 9 out of the total 16 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 1.7% 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. 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 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 the uncertainty of the litigation, the Company has recorded its Visa Class B shares on its statements of condition at zero value for all reporting periods since 2008. At March 31, 2018 , the Company owned 11,623 of Visa Class B shares with a then current conversion ratio to Visa Class A shares of 1.648 (or 19,158 Visa Class A shares). Upon termination of the existing transfer restriction and settlement of the litigation, and to the extent the Company continues to own such Visa Class B shares in the future, the Company expects to record its Visa Class B shares at fair value.

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 nonperforming 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 three months ended March 31, 2018 and for the three months ended March 31, 2017 , 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. The modifications for the three months ended March 31, 2018 were attributable to interest rate concessions, maturity date extensions, reamortization or a combination of two concessions. The modifications for the three months ending March 31, 2017 were attributable to interest rate concessions, maturity date extensions, or a combination of both.

LOAN LOSS ALLOWANCE

LOAN LOSS ALLOWANCE	3 Months Ended
	Mar. 31, 2018
Receivables [Abstract]
LOAN LOSS ALLOWANCE	LOAN LOSS ALLOWANCE The allowance for loan losses is maintained at a level considered adequate to provide for our estimate of probable credit losses inherent in the loan portfolio. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. Loans are charged against the allowance for loan losses when we believe that collectability is unlikely. While we use the best information available to make our 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 we employ on a quarterly basis with respect to each of these components in order to evaluate the overall adequacy of our allowance for loan losses is as follows: Specific Reserve for Loans Individually Evaluated First, we identify loan relationships having aggregate balances in excess of $150 thousand and that may also have credit weaknesses. Such loan relationships are identified primarily through our analysis of internal loan evaluations, past due loan reports and loans adversely classified internally or by regulatory authorities. 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 Bank will be unable to collect all amounts due according to the contractual terms of the original loan agreement. Substantially all of our 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, we measure 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. Our 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, we stratify 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, we consider the necessity to adjust our 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 Bank’s loan review system, (7) concentrations in the 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 was generated utilizing a charge-off look-back analysis, which studied 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 established 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 three months ended March 31, 2018 and 2017 was as follows: Business Activities Loans At or for the Three Months Ended March 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 — (84 ) — (170 ) (254 ) Recoveries on charged-off loans 15 2 1 2 20 Provision/(releases) for loan losses (54 ) 321 (54 ) 282 495 Balance at end of period $ 5,998 $ 2,612 $ 3,304 $ 500 $ 12,414 Individually evaluated for impairment 433 132 84 — 649 Collectively evaluated 5,565 2,480 3,220 500 11,765 Total $ 5,998 $ 2,612 $ 3,304 $ 500 $ 12,414 Business Activities Loans At or for the Three Months Ended March 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 (107 ) (17 ) (199 ) (21 ) (344 ) Recoveries on charged-off loans 4 — 1 9 14 Provision/(releases) for loan losses 265 208 283 39 795 Balance at end of period $ 5,307 $ 2,143 $ 2,806 $ 628 $ 10,884 Individually evaluated for impairment 302 172 45 8 527 Collectively evaluated 5,005 1,971 2,761 620 10,357 Total $ 5,307 $ 2,143 $ 2,806 $ 628 $ 10,884 Acquired Loans At or for the Three Months Ended March 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 (106 ) (58 ) — (43 ) (207 ) Recoveries on charged-off loans — — — — — Provision/(releases) for loan losses 92 166 (1 ) 43 300 Balance at end of period $ 83 $ 124 $ 58 $ — $ 265 Individually evaluated for impairment — 121 — — 121 Collectively evaluated 83 3 58 — 144 Total $ 83 $ 124 $ 58 $ — $ 265 There was no allowance for loans meeting the definition of acquired for the three month period ending March 31, 2017 . Loan Origination/Risk Management: The Bank has certain lending policies and procedures in place are designed to maximize loan income within an acceptable level of risk. The Bank’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 Bank's Board of Directors with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing loans and potential problem loans. The Bank 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 Bank 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 Bank’s credit quality indicators: Pass: Loans within all classes of 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 that do not expose the Bank to risk sufficient to warrant classification in one of the subsequent categories, but which possess some weaknesses, 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 the lending officer may be unable to supervise properly because of: (i) lack of expertise, inadequate loan agreement; (ii) the poor condition of or lack of control over collateral; or (iii) 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 Bank to sufficient risks to warrant classification. Substandard: The Bank considers a loan substandard if it is 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 Bank classifies as doubtful have all of the weaknesses inherent in those loans that are classified as substandard.These loans have the added characteristic of the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. 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 Bank classifies 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.

There was no outstanding balance on the FHLB line of credit for the periods ended March 31, 2018 and December 31, 2017 . The Bank also had 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 March 31, 2018 , the Bank’s available secured line of credit at the FRB was $118.0 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 March 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 March 31, 2018 include callable advances totaling $25.0 million , and amortizing advances totaling $676 thousand . The advances outstanding at December 31, 2017 include callable advances totaling $27.0 million , and $683 thousand 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 March 31, 2018 is as follows: March 31, 2018 (in thousands, except rates) Carrying Value Weighted Average Rate Fixed rate advances maturing: 2018 $ 531,680 1.78 % 2019 146,661 1.88 2020 29,929 1.88 2021 1,637 2.35 2022 — — 2023 and thereafter 676 2.87 Total FHLB advances $ 710,583 1.81 % In April 2008, the Bank issued fifteen year junior subordinated notes in the amount of $5.0 million . 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 March 31, 2018 and December 31, 2017 the interest rate was 5.57% 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 3-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.

CAPITAL RATIOS AND SHAREHOLDERS' EQUITY	CAPITAL RATIOS AND SHAREHOLDERS’ EQUITY The actual and required capital ratios were as follows: March 31, 2018 Regulatory Minimum to be "Well Capitalized" December 31, 2017 Regulatory Minimum to be "Well Capitalized" Company (consolidated) Total capital to risk weighted assets 13.9 % 10.5 % 13.7 % 10.5 % Common equity tier 1 capital to risk weighted assets 11.4 6.5 11.3 6.5 Tier 1 capital to risk weighted assets 12.3 8.0 12.2 8.0 Tier 1 capital to average assets 8.2 5.0 8.1 5.0 Bank Total capital to risk weighted assets 13.7 % 10.5 % 13.7 % 10.5 % Common equity tier 1 capital to risk weighted assets 12.9 6.5 12.9 6.5 Tier 1 capital to risk weighted assets 12.9 8.0 12.9 8.0 Tier 1 capital to average assets 8.6 5.0 8.6 5.0 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 March 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 March 31, 2018 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 1.875% .

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 Bank periodically uses derivative instruments to minimize significant unplanned fluctuations in earnings and cash flows caused by interest rate volatility. The Bank’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 Bank designates whether the derivative is part of a hedging relationship (i.e., cash flow or fair value hedge). The Bank formally documents relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking hedge transactions. The Bank 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 Bank 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 March 31, 2018 and December 31, 2017 , was as follows: March 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 4.9 $ 1,215 Total cash flow hedges 90,000 4.9 1,215 Economic hedges: Forward sale commitments 5,658 0.2 (51 ) Total economic hedges 5,658 0.2 (51 ) Non-hedging derivatives: Interest rate lock commitments 4,375 0.2 7 Total non-hedging derivatives 4,375 0.2 7 Total $ 100,033 $ 1,171 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 5.1 669 Economic hedges: Forward sale commitments 20,352 0.2 (221 ) Total economic hedges 20,352 0.2 (221 ) Non-hedging derivatives: Interest rate lock commitments 19,853 0.2 (1 ) Total non-hedging derivatives 19,853 0.2 (1 ) Total $ 130,205 $ 447 Information about derivative assets and liabilities for the three months ended March 31, 2018 and 2017 , was as follows: Three Months Ended March 31, (in thousands) 2018 2017 Cash flow hedges: Interest rate cap agreements Realized (loss) in interest expense $ (108 ) $ (39 ) Economic hedges: Forward commitments Realized gain/(loss) in other non-interest income 170 (78 ) Non-hedging derivatives: Interest rate lock commitments Realized gain in other non-interest income 8 2 Cash flow hedges In 2014, interest rate cap agreements were purchased to limit the Bank’s exposure to rising interest rates on four rolling, three-month borrowings indexed to three-month LIBOR. Under the terms of the agreements, the Bank paid total premiums of $4.6 million for the right to receive cash flow payments if 3-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 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 mortgage loans will be 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 changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and 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.

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 March 31, 2018 and December 31, 2017 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value. March 31, 2018 Level 1 Level 2 Level 3 Total (in thousands) Inputs Inputs Inputs Fair Value Available for sale securities: Obligations of US Government sponsored enterprises $ — $ 6,977 $ — $ 6,977 Mortgage-backed securities: US Government-sponsored enterprises — 449,175 — 449,175 US Government agency — 90,396 — 90,396 Private label — 616 — 616 Obligations of states and political subdivisions thereof — 135,277 — 135,277 Corporate bonds — 36,118 — 36,118 Derivative assets — 1,215 7 1,222 Derivative liabilities — — (51 ) (51 ) December 31, 2017 Level 1 Level 2 Level 3 Total (in thousands) Inputs Inputs Inputs 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 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 of a 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 not considered observable factors. As such, mandatory delivery forward commitments are classified as Level 3 measurements. The table below presents the changes in Level 3 assets and liabilities that were measured at fair value on a recurring basis for the three months ended March 31, 2018 .

There were no Level 1 or Level 2 non-recurring fair value measurements for the periods ended March 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 relating to real estate collateral have generally been classified as Level 3. Estimates of fair value for other collateral supporting 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 estimated fair values, and related carrying amounts, of the Company’s financial instruments follow.

Cash and cash equivalents. Carrying value is assumed to represent fair value for cash and cash equivalents that have original maturities of 90 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 March 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 90 days. Off-balance-sheet financial instruments. Off-balance-sheet financial instruments include standby letters of credit and other financial guarantees and commitments are considered immaterial to the Company’s financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 (“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 GAAP requires otherwise. In addition, these interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and note disclosures for the Company's Annual Report on Form 10-K for the year ended December 31, 2017 previously filed with the Securities and Exchange Commission (the "SEC"). In management's opinion, all adjustments necessary for a fair statement are reflected in the interim periods presented.
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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following table provides a brief description of recent accounting standards updates (ASU") 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 $241,000 liability with a $184,000 impact to retained earnings net of tax. The remaining changes had no material impact on the consolidated financial statements. See below 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 notion pricing 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements. 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 postretirement 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 adoption of this ASU did not have a material impact on the Company's consolidated financial statements. Early adoption is permitted. Standard Description Required Date of Adoption Effect on financial statements Standards Adopted in 2018 (continued) 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 adoption of this ASU 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 $980,000 with zero net effect on total stockholders' equity. ASU 2018-05, Income Taxes (Topic 740) SEC Amendments Early adoption is permitted. 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 should be adopted on a modified retrospective basis. January 1, 2019 The Company is currently evaluating its operating lease arrangement under this ASU. Early indications suggest the Company will need to recognize right-of-use assets and lease liabilities for most of its operating lease commitments. ASU 2018-01, Leases (Topic 842) Land Easement Practical Expedient for Transition to Topic 842 Standard Description Required Date of Adoption Effect on financial statements Standards Not Yet Adopted (continued) 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. 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 AFS 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. 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.
