Basis of Presentation (Policies)	9 Months Ended
Sep. 30, 2019
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, 2019, the consolidated results of income and comprehensive income for the three and nine months ended September 30, 2019 and 2018, changes in stockholders’ equity for the three and nine months ended September 30, 2019 and cash flows for the nine months ended September 30, 2019 and 2018, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2018 were derived from the 2018 audited financial statements. The results of operations for the three and nine months ended September 30, 2019 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, 2018. For purposes of comparability, certain immaterial 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 subsidiary.
Recent Accounting Standards	Recent Accounting Standards ASU No. 2016-13 - In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. At the FASB’s October 16, 2019 meeting, the Board affirmed its decision to amend the effective date of this ASU for many companies. Public business entities that are SEC filers, excluding those meeting the smaller reporting company definition, will retain the initial required implementation date of fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. All other entities will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022. At this time, the Company has established a project management team which meets periodically to discuss and assign roles and responsibilities, key tasks to complete, and a general timeline to be followed for implementation. The team has been working with an advisory consultant and has purchased a vendor model for implementation. Historical data has been collected and uploaded to the new model and the team is in the process of finalizing the methodologies that will be utilized. The team is currently running a parallel simulation to its current incurred loss impairment model. The Company is continuing to evaluate the extent of the potential impact of this standard and continues to keep current on evolving interpretations and industry practices via webcasts, publications, conferences, and peer bank meetings. ASU No. 2017-04 – In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”. The amendments in this ASU simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are U.S. Securities and Exchange Commission (SEC) filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The guidance is not expected to have a significant impact on the Company’s financial positions, results of operations or disclosures. ASU No. 2018-13 – In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The amendments modify the disclosure requirements in Topic 820 to add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty. Certain disclosure requirements in Topic 820 are also removed or modified. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Certain of the amendments are to be applied prospectively while others are to be applied retrospectively. Early adoption is permitted. As ASU No. 2018-13 only revises disclosure requirements, it will not have a material impact on the Company’s Consolidated Financial Statements. ASU No. 2019-04 – In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” This ASU clarifies and improves areas of guidance related to the recently issued standards on credit losses, hedging, and recognition and measurement including improvements resulting from various TRG Meetings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-04 will have on its consolidated financial statements. ASU No. 2019-05 - In May 2019, the FASB issued ASU 2019-05, “Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief.” The amendments in this ASU provide entities that have certain instruments within the scope of Subtopic 326-20 with an option to irrevocably elect the fair value option in Subtopic 825-10, applied on an instrument-by-instrument basis for eligible instruments, upon the adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. An entity that elects the fair value option should subsequently measure those instruments at fair value with changes in fair value flowing through earnings. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments should be applied on a modified-retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings balance in the balance sheet. Early adoption is permitted. The Company is currently assessing the impact that ASU 2019-04 will have on its consolidated financial statements.
