Basis of Presentation (Policies)	9 Months Ended
Sep. 30, 2016
Basis of Presentation [Abstract]
Basis of Presentation	The consolidated financial statements include the accounts of Shore Bancshares, Inc. and its subsidiaries with all significant intercompany transactions eliminated. The consolidated financial statements conform to accounting principles generally accepted in the United States of America (“GAAP”) and to prevailing practices within the banking industry. The accompanying interim financial statements are unaudited; however, in the opinion of management all adjustments necessary to present fairly the consolidated financial position at September 30, 2016, the consolidated results of operations and comprehensive income for the three and nine months ended September 30, 2016 and 2015, and changes in stockholders’ equity and cash flows for the nine months ended September 30, 2016 and 2015, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2015 were derived from the 2015 audited financial statements. The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results to be expected for any other interim period or for the full year. This Quarterly Report on Form 10-Q should be read in conjunction with the Annual Report of Shore Bancshares, Inc. on Form 10-K for the year ended December 31, 2015. For purposes of comparability, certain reclassifications have been made to amounts previously reported to conform with the current period presentation. When used in these notes, the term “the Company” refers to Shore Bancshares, Inc. and, unless the context requires otherwise, its consolidated subsidiaries. Effective July 1, 2016, the Company’s two bank subsidiaries, The Talbot Bank of Easton Maryland and CNB were consolidated into one bank known as Shore United Bank. In these notes to the consolidated financial statements and the management discussion and analysis section, the term “the Bank” refers to Shore United Bank, unless the context requires stipulating results of the individual banks before the consolidation occurred.
Recent Accounting Standards	Recent Accounting Standards ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” amendment requires entities to recognize revenue to depict the transfer of promised goods or services to customers in amounts that reflect the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for periods beginning after January 1, 2017. ASU 2015-14, “Revenue from Contracts with Customers (Topic 606) Deferral of the Effective Date ” – ASU 2015-14 amendments defer the effective date of Update 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations” – ASU 2016-08 amendments are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” – ASU 2016-10 amendments clarify that contractual provisions that, explicitly or implicitly, require an entity to transfer control of additional goods or services to a customer should be distinguished from contractual provisions that, explicitly or implicitly, define the attributes of a single promised license. Attributes of a promised license define the scope of a customer’s right to use or right to access an entity’s intellectual property and, therefore, do not define whether the entity satisfies its performance obligation at a point in time or over time and do not create an obligation for the entity to transfer any additional rights to use or access its intellectual property. The Company is evaluating the impact that ASU 2014-09 and all amendments thereof will have on our consolidated financial statements. ASU 2014-12, "Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718, Compensation - Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. However, compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. The amendments in this ASU are effective for interim or annual reporting periods beginning after December 15, 2015; early adoption is permitted. Entities may apply the amendments in this ASU either: (1) prospectively to all awards granted or modified after the effective date; or (2) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. As of September 30, 2016, the Company has share-based payment awards that included performance targets that could be achieved after the requisite service period. The adoption of ASU No. 2014-12 did not have a material impact on the Company's Consolidated Financial Statements. ASU No. 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU No. 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. The adoption of ASU No. 2015-05 did not have a material impact on the Company's Consolidated Financial Statements. ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. ASU 2016-01 will be effective for us on January 1, 2018 and is not expected to have a significant impact on our financial statements. ASU No. 2016-02, “Leases (Topic 842).” This ASU stipulates that a lessee should recognize the assets and liabilities that arise from leases. All leases create an asset and a liability for the lessee in accordance with FASB Concepts Statement No. 6, Elements of Financial Statement , and, therefore, recognition of those lease assets and lease liabilities represents an improvement over previous GAAP, which did not require lease assets and lease liabilities to be recognized for most leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. When measuring assets and liabilities arising from a lease, a lessee (and a lessor) should include payments to be made in optional periods only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. Similarly, optional payments to purchase the underlying asset should be included in the measurement of lease assets and lease liabilities only if the lessee is reasonably certain to exercise that purchase option. In addition, also consistent with the previous leases guidance, a lessee (and a lessor) should exclude most variable lease payments in measuring lease assets and lease liabilities, other than those that depend on an index or a rate or are in substance fixed payments. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in this Update is permitted for all entities. The Company is evaluating the impact that ASU 2016-02 will have on our consolidated financial statements. ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This ASU simplifies the treatment and accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is evaluating the impact that ASU 2016-09 will have on our consolidated financial statements. ASU No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU will replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The amendments broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit losses, which will be more decision useful to users of the financial statements. It is not expected that an entity will need to create an economic forecast over the entire contractual life of long-dated financial assets. Therefore, the amendments will allow an entity to revert to historical loss information that is reflective of the contractual term (considering the effect of prepayments) for periods that are beyond the time frame for which the entity is able to develop reasonable and supportable forecasts. The amendments retain many of the disclosure amendments in Accounting Standards Update No. 2010-20, Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses, updated to reflect the change from an incurred loss methodology to an expected credit loss methodology. Credit losses on available-for-sale debt securities should be measured in a manner similar to current GAAP. However, the amendments require that credit losses be presented as an allowance rather than a write-down. For public entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments earlier as of the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company believes this ASU will have a significant impact on our consolidated financial statements and the method in which we calculate our credit losses, primarily on loans and available-for sale securities. At this time, the Company will continue to evaluate the impact and implementation of this standard to meet the effective date for consolidated financial statements beginning in 2019. ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments." Current GAAP is unclear or does not include specific guidance on how to classify certain transactions in the statement of cash flows. This ASU is intended to reduce diversity in practice in how eight particular transactions are classified in the statement of cash flows. ASU No. 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, provided that all of the amendments are adopted in the same period. Entities will be required to apply the guidance retrospectively. If it is impracticable to apply the guidance retrospectively for an issue, the amendments related to that issue would be applied prospectively. As this guidance only affects the classification within the statement of cash flows, ASU No. 2016-15 is not expected to have a material impact on the Company's consolidated financial statements.
