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.

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		January 1, 2019

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.
