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 March 31, 2022, the consolidated results of income and comprehensive income for the three months ended March 31, 2022 and 2021, changes in stockholders’ equity for the three months ended March 31, 2022 and 2021 and cash flows for the three months ended March 31, 2022 and 2021, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2021 were derived from the 2021 audited financial statements. The results of operations for the three months ended March 31, 2022 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, 2021. 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”).
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. The FASB has issued multiple updates to ASU 2016-13 as codified in Topic 326, including ASU’s 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, and 2020-03. These ASU’s have provided for various minor technical corrections and improvements to the codification as well as other transition matters. Smaller reporting companies who file with the U.S. Securities and Exchange Commission (SEC) and all other entities who do not file with the SEC are 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 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. 2022-02 – In March 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2022-02, “Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 addresses areas identified by the FASB as part of its post-implementation review of the credit losses standard (ASU 2016-13) that introduced the CECL model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the CECL model and enhance the disclosure requirements for loan refinancing’s and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require a public business entity to disclose current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. The amendments in this ASU should be applied prospectively, except for the transition method related to the recognition and measurement of troubled debt restructurings (TDR), an entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. For entities that have adopted ASU 2016-13, ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For entities that have not yet adopted ASU 2016-13, the effective dates for ASU 2022-02 are the same as the effective dates in ASU 2016-13. Early adoption is permitted if an entity has adopted ASU 2016-13. An entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. The Company is currently assessing the impact that ASU 2022-02 will have on its consolidated financial statements. 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. Subsequently, in January 2021, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2021-01 “Reference Rate Reform (Topic 848): Scope.” This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply ASU No. 2021-01 on contract modifications that change the interest rate used for margining, discounting, or contract price alignment retrospectively as of any date from the beginning of the interim period that includes March 12, 2020, or prospectively to new modifications from any date within the interim period that includes or is subsequent to January 7, 2021, up to the date that financial statements are available to be issued. An entity may elect to apply ASU No. 2021-01 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020, and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. At present, the Bank has limited exposure to LIBOR based pricing. LIBOR based loans only comprise 24 loans or 4.7% 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.
