Basis of Presentation [Abstract]
Basis of Presentation	The consolidated financial statements include the accounts of Shore Bancshares, Inc. and its subsidiary 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 June 30, 2021, the consolidated results of income and comprehensive income for the three and six months ended June 30, 2021 and 2020, changes in stockholders’ equity for the three and six months ended June 30, 2021 and 2020 and cash flows for the six months ended June 30, 2021 and 2020, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2020 were derived from the 2020 audited financial statements. The results of operations for the three and six months ended June 30, 2021 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, 2020. 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, Shore United Bank (the “Bank”).
Risks and Uncertainties	Risks and Uncertainties Since the novel coronavirus ("COVID-19") was declared a pandemic in March 2020, COVID-19 has significantly affected our communities, customers, and operations. COVID-19 continues to have a significant impact in 2021, however, the extent of its effects are dependent upon multiple factors, such as the extent of distribution and efficacy of vaccines, COVID-19 variants, pandemic-related restrictions, and government response, among others. As a result, the ultimate effects of COVID-19 over the longer term cannot be reasonably estimated at this time. Risks and uncertainties arising from the pandemic remain, primarily concerning the ability of customers to fulfill their financial obligations to the Company as well as potential operational disruptions and the ability of the Company to generate demand for its products and services. Accordingly, estimates used in the preparation of our financial statements may be subject to significant adjustments in future periods.
Recent Accounting Standards and Other Authoritative Guidance	Recent Accounting Standards and Other Authoritative Guidance 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, retained 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. Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB ASC 326, “Financial Instruments – Credit Losses.” It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology. ASU No. 2020-04 – In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. At present, the Bank has limited exposure to LIBOR based pricing. LIBOR based loans only comprise 26 loans or 7.6% of the loan portfolio. The Bank is confident it can successfully negotiate a migration to the Secured Overnight Financing Rate (“SOFR”) between now and the implementation date. The Bank will notify customers within 120 days prior to migration to SOFR. The Bank acknowledges the replacement rate will be more volatile based on different countries migrating to different indexes and limited liquidity to support the rate. The Bank further acknowledges the volatility will be greatly influenced by the support provided by the Federal Reserve. ASU No. 2021-04 - In May 2021, the FASB issued ASU 2021-04, “Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity – Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force).” The ASU addresses how an issuer should account for modifications or an exchange of freestanding written call options classified as equity that is not within the scope of another Topic. For both public and private companies, the ASU is effective for fiscal years beginning after December 15, 2021. Transition is prospective. Early adoption is permitted. The Company does not expect the adoption of ASU 2021-04 to have a material impact on its consolidated financial statements. Recent Accounting Developments In December 2020, the Consolidated Appropriations Act of 2021 (“CAA”) was passed. Under Section 541 of the CAA, Congress extended or modified many of the relief programs first created by the CARES Act, including the PPP loan program and treatment of certain loan modifications related to the COVID-19 pandemic. The Bank participated in the second round of PPP lending under the CAA, which resulted in 959 PPP loans for approximately $67.3 million. In addition, two hospitality loans remained in the COVID-19 relief program under the CARES Act.
