Organization, Consolidation and Presentation of Financial Statements [Abstract]

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.

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 SEC 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 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 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.
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 bank'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 adoption of this ASU had no 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 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		January 1, 2019
ASU 2018-10, Codification Improvements to Topic 842, Leases



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 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.
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.
ASU 2017-04, Simplifying the Test for Goodwill Impairment		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 2018-07, Share Based Payment Accounting	This ASU expands the scope of Topic 718, Compensation- Stock Compensation to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity-Based Payments to Non-Employees.	January 1, 2019	The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements. The Company does not participate in these types of arrangements in the normal course of business, except for board director compensation.
ASU 2018-09, Codification Improvements	This ASU does not prescribe any new accounting guidance, but instead makes minor improvements and clarifications of several different areas based on comments and suggestions by various stakeholders. Topics that may be relevant to the company currently or in the future include (1) comprehensive income, (2) income tax for stock compensation and business combinations, (3) derivatives and hedging, and (4) fair value measurements.	January 1, 2019	The Company is currently evaluating this guidance to determine any impact on the Company's consolidated financial statements.

Adoption of ASC 606, Revenue from Contracts with Customers

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.

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.

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.

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.

- Definition

Disclosure of accounting policy for income taxes, which may include its accounting policies for recognizing and measuring deferred tax assets and liabilities and related valuation allowances, recognizing investment tax credits, operating loss carryforwards, tax credit carryforwards, and other carryforwards, methodologies for determining its effective income tax rate and the characterization of interest and penalties in the financial statements.
