Basis of Presentation [Abstract]
Basis of Presentation	Note 1 - 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, 2018 , the consolidated results of income and comprehensive income for the three months ended March 31, 2018 and 2017 , and changes in stockholders’ equity and cash flows for the three months ended March 31, 2018 and 2017 , have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2017 were derived from the 2017 audited financial statements. The results of operations for the three months ended March 31, 2018 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, 2017 . 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 subsidiaries.  Recent Accounting Standards 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 in this ASU are effective for fiscal years after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Leases and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU No. 2016-02 will have on its consolidated financial statements. The Company has put together a team to inventory all leases and accumulate the lease data necessary to apply the amended guidance. 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 held to maturity securities. At this time, the Company has established a project management team which is in the process of developing an adoption process and understanding this pronouncement, evaluating the impact of this pronouncement and researching additional software resources that could assist with the implementation.  ASU No. 2017-04 – In January 2017, FASB issued ASU No. 2017-04, “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The ASU simplifies measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The Company should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The impairment charge is limited to the amount of goodwill allocated to that reporting unit. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for 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. 2017-08 – In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. This guidance shortens the amortization period of certain callable debt securities held at a premium to the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements.  ASU No. 2017-09 – In May 2017, the FASB issued ASU No. 2017-09 “Stock Compensation, Scope of Modification Accounting.” This ASU clarifies when changes to the terms of conditions of a share-based payment award must be accounted for as modifications. Companies will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The new guidance should reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications, as the guidance will allow companies to make certain non-substantive changes to awards without accounting for them as modifications. It does not change the accounting for modifications. ASU No. 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017; early adoption is permitted. ASU No. 2017-09 is not expected to have a material impact on the Company’s consolidated financial statements.  ASU 2018-02 – In February 2018, the FASB issued ASU No. 2018-02 “Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The amendments provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Organizations should apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company has elected to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act in the financial statements for the period ending December 31, 2017. The amount of this reclassification in 2017 was $226 thousand.  ASU 2018-03 - In February 2018, the FASB issued ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments provide targeted improvements to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Specifically, the amendments include clarifications related to: measurement elections, transition requirements, and adjustments associated with equity securities without readily determinable fair values; fair value measurement requirements for forward contracts and purchased options on equity securities; presentation requirements for hybrid financial liabilities for which the fair value option has been elected; and measurement requirements for liabilities denominated in a foreign currency for which the fair value option has been elected. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. Early adoption is permitted. The adoption of ASU No. 2018-03 is not expected to have a material impact on the Company’s consolidated financial statements.

Business Combination [Abstract]
Business Combination	Note 2 – Business Combination  Northwest Bank Branch Acquisition  On May 19, 2017, the Bank purchased three branches from Northwest Bank (“NWBI”) located in Arbutus, Elkridge, and Owings Mills, Maryland. Pursuant to the transaction, the Bank acquired $122.9 million in loans and $212.5 million in deposits, as well as the branch premises and equipment. In connection with its purchase of the branches from NWBI, the Bank received a cash payment from NWBI of $64.0 million, which was net of a premium paid on deposits of $17.2 million. In addition to the premium paid on deposits, other costs associated with the acquisition totaled $977 thousand. This acquisition provides the Bank with the opportunity to enhance its footprint in Maryland by extending its branch network across the Chesapeake Bay to the greater Baltimore area communities of Elkridge, Owings Mills and Arbutus.  The Company has accounted for the branch purchases under the acquisition method of accounting in accordance with FASB ASC topic 805, “Business Combinations,” whereby the acquired assets and liabilities were recorded by the Bank at their estimated fair values as of their acquisition date.  The acquired assets and assumed liabilities of the NWBI branches were measured at estimated fair value. Management made significant estimates and exercised significant judgement in accounting for the acquisition of the NWBI branches. Management evaluated expected cash flows, prepayment speeds and estimated loss factors to measure fair values for loans. Deposits were valued based upon interest rates, original and remaining terms and maturities, as well as current rates for similar funds in the same markets. Premises were based on recent appraised values, whereas equipment was acquired based on the remaining book value from NWBI, which approximated fair value. Management engaged independent outside experts to provide the fair value estimates. Subsequent to the purchase, Management made a measurement period adjustment for deferred taxes related to intangible assets of $291 thousand .  The following table provides the purchase price as of the acquisition date of May 19, 2017, the identifiable assets acquired and liabilities assumed at their estimated fair values, and the resulting goodwill of $15.0 million recorded from the acquisition: (in thousands)    Purchase Price Consideration:  Cash consideration $ 17,186  Total purchase price for NWBI branch acquisition $ 17,186   Assets acquired at fair value:  Cash and cash equivalents $ 81,231  Loans 122,862  Premises and equipment, net 6,326  Core deposit intangible 3,954  Deferred tax assets 291  Total fair value of assets acquired $ 214,664   Liabilities assumed at fair value:  Deposits $ 212,456  Other liabilities 7  Total fair value of liabilities assumed $ 212,463   Net assets acquired at fair value: $ 2,201   Amount of goodwill resulting from acquisition $ 14,985  The total amount of goodwill arising from this transaction of $15.0 million is expected to be deductible for tax purposes, pursuant to section 197 of the Internal Revenue Code.            Acquired loans  The following table outlines the contractually required payments receivable, cash flows we expect to receive, and the accretable yield for all NWBI loans as of the acquisition date.     Contractually  Required Cash Flows Carrying Value  Payments Expected To Be Accretable FMV of Loans  Receivable Collected Adjustments Receivable   Performing loans acquired $ 125,131 125,131 2,269 $ 122,862   The Company recorded all loans acquired at the estimated fair value on the purchase date with no carryover of the related allowance for loan losses. The Company only acquired loans which were deemed to be performing loans with no signs of credit deterioration.  The Company determined the net discounted value of cash flows on approximately 864 performing loans totaling $125.1 million. The valuation took into consideration the loans’ underlying characteristics, including account types, remaining terms, annual interest rates, interest types, past delinquencies, timing of principal and interest payments, current market rates, loan-to-value ratios, loss exposures, and remaining balances. These performing loans were segregated into pools based on loan and payment type. The effect of this fair valuation process was a net accretable discount adjustment of $2.3 million at acquisition.

The unrealized losses on debt securities that exist are the result of market changes in interest rates since original purchase. Because the Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized cost bases, which may be at maturity for debt securities, the Company considers the unrealized losses to be temporary. There were eighty-three available-for-sale securities and one held-to-maturity security in an unrealized loss position at March 31, 2018.

Loans and Allowance for Credit Losses [Abstract]
Loans and Allowance for Credit Losses	Note 5 – Loans and Allowance for Credit Losses The Company makes residential mortgage, commercial and consumer loans to customers primarily in Talbot County, Queen Anne’s County, Kent County, Caroline County, Dorchester County, Baltimore County and Howard County in Maryland, Kent County, Delaware and Accomack County, Virginia. The following table provides information about the principal classes of the loan portfolio at March 31, 2018 and December 31, 2017 .   (Dollars in thousands) March 31, 2018 December 31, 2017  Construction $ 130,455 $ 125,746  Residential real estate 401,359 399,190  Commercial real estate 477,805 464,887  Commercial 104,266 97,284  Consumer 6,052 6,407  Total loans 1,119,937 1,093,514  Allowance for credit losses (9,918) (9,781)  Total loans, net $ 1,110,019 $ 1,083,733 Loans are stated at their principal amount outstanding net of any purchase premiums, deferred fees and costs. Loans included deferred costs, net of deferred fees, of $644 thousand and discounts on acquired loans of $1.8 million at March 31, 2018. Loans included deferred costs, net of deferred fees, of $609 thousand and discounts on acquired loans of $1.8 million at December 31, 201 7 . Interest income on loans is accrued at the contractual rate based on the principal amount outstanding. fees charged and costs capitalized for originating loans are being amortized substantially on the interest method over the term of the loan. A loan is placed on nonaccrual (i.e., interest income is no longer accrued) when it is specifically determined to be impaired or when principal or interest is delinquent for 90 days or more, unless the loan is well secured and in the process of collection. Any unpaid interest previously accrued on those loans is reversed from income. Also included in total loans at March 31, 2018 and December 31, 2017 were $104.8 million and $108.1 million in loans acquired in the second quarter of 2017 as part of the NWBI branch acquisition. Interest payments received on nonaccrual loans are applied as a reduction of the loan principal balance unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. A loan is considered impaired if it is probable that the Company will not collect all principal and interest payments according to the loan’s contractual terms. An impaired loan may show deficiencies in the borrower’s overall financial condition, payment history, support available from financial guarantors and/or the fair market value of collateral. The impairment of a loan is measured at the present value of expected future cash flows using the loan’s effective interest rate, or at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Generally, the Company measures impairment on such loans by reference to the fair value of the collateral. Once the amount of impairment has been determined, the uncollectible portion is charged off. Income on impaired loans is recognized on a cash basis, and payments are first applied against the principal balance outstanding (i.e., placing impaired loans on nonaccrual status). Generally, interest income is not recognized on impaired loans unless the likelihood of further loss is remote. The allowance for credit losses may include specific reserves related to impaired loans. Specific reserves remain until charge offs are made. Impaired loans do not include groups of smaller balance homogenous loans such as residential mortgage and consumer installment loans that are evaluated collectively for impairment. Reserves for probable credit losses related to these loans are based on historical loss ratios and are included in the formula portion of the allowance for credit losses. See additional discussion under the caption “Critical Accounting Policies” in Management’s Discussion and Analysis of Financial Condition and Results of Operations. A loan is considered a troubled debt restructuring (“TDR”) if a borrower is experiencing financial difficulties and a creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses. Loans are identified to be restructured when signs of impairment arise such as borrower interest rate reduction request, slowness to pay, or when an inability to repay becomes evident. The terms being offered are evaluated to determine if they are more liberal than those that would be indicated by policy or industry standards for similar, untroubled credits. In those situations where the terms or the interest rates are considered to be more favorable than industry standards or the current underwriting guidelines of the Company’s banking subsidiary, Shore United Bank (the “Bank”), the loan is classified as a TDR. All loans designated as TDRs are considered impaired loans and may be on either accrual or nonaccrual status. In instances where the loan has been placed on nonaccrual status, six consecutive months of timely payments are required prior to returning the loan to accrual status.   All loans classified as TDRs which are restructured and accrue interest under revised terms require a full and comprehensive review of the borrower’s financial condition, capacity for repayment, realistic assessment of collateral values, and the assessment of risk entered into any workout agreement. Current financial information on the borrower, guarantor, and underlying collateral is analyzed to determine if it supports the ultimate collection of principal and interest. For commercial loans, the cash flows are analyzed, both for the underlying project and globally. For consumer loans, updated salary, credit history and cash flow information is obtained. Current market conditions are also considered. Following a full analysis, the determination of the appropriate loan structure is made. In the normal course of banking business, risks related to specific loan categories are as follows: Construction loans – Construction loans are offered primarily to builders and individuals to finance the construction of single family dwellings. In addition, the Bank periodically finances the construction of commercial projects. Credit risk factors include the borrower’s ability to successfully complete the construction on time and within budget, changing market conditions which could affect the value and marketability of projects, changes in the borrower’s ability or willingness to repay the loan and potentially rising interest rates which can impact both the borrower’s ability to repay and the collateral value.  Residential real estate – Residential real estate loans are typically made to consumers and are secured by residential real estate. Credit risk arises from the borrower’s continuing financial stability, which can be adversely impacted by job loss, divorce, illness, or personal bankruptcy, among other factors. Also impacting credit risk would be a shortfall in the value of the residential real estate in relation to the outstanding loan balance in the event of a default or subsequent liquidation of the real estate collateral. Commercial real estate – Commercial real estate loans consist of both loans secured by owner occupied properties and non-owner occupied properties where an established banking relationship exists and involves investment properties for warehouse, retail, and office space with a history of occupancy and cash flow. These loans are subject to adverse changes in the local economy and commercial real estate markets. Credit risk associated with owner occupied properties arises from the borrower’s financial stability and the ability of the borrower and the business to repay the loan. Non-owner occupied properties carry the risk of a tenant’s deteriorating credit strength, lease expirations in soft markets and sustained vacancies which can adversely impact cash flow. Commercial – Commercial loans are secured or unsecured loans for business purposes. Loans are typically secured by accounts receivable, inventory, equipment and/or other assets of the business. Credit risk arises from the successful operation of the business which may be affected by competition, rising interest rates, regulatory changes and adverse conditions in the local and regional economy. Consumer – Consumer loans include home equity loans and lines, installment loans and personal lines of credit. Credit risk is similar to residential real estate loans above as it is subject to the borrower’s continuing financial stability and the value of the collateral securing the loan.   The following tables include impairment information relating to loans and the allowance for credit losses as of March 31, 2018 and December 31, 2017 .

The Company added pass/watch credits to an existing pool that included loans that are risk rated as special mention and substandard to be collectively evaluated for impairment for both quantitative and qualitative factors at December 31, 2017. The Company believes that attributing additional reserves to this pool of loans better reflects the perceived risk for the total loan portfolio going forward, due to the significant organic loan growth over the past 24 months, the increase in pass/watch rated credits, and increasing balances/concentrations in certain segments of the loan portfolio. Loans that are identified as special mention, substandard or doubtful are adversely rated. They are assigned higher risk ratings than favorably rated loans in the calculation of the formula portion of the allowance for credit losses. At March 31, 2018, there were no nonaccrual loans classified as special mention or doubtfu l and $7.0 million of nonaccrual loans were identified as substandard. Similarly, at December 31, 2017, there were no nonaccrual loans classified as special mention or doubtful and $5.0 million of nonaccrual loans were identified as substandard.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 9 - Stock-Based Compensation At the 2016 annual meeting, stockholders approved the Shore Bancshares, Inc. 2016 Stock and Incentive Plan (“2016 Equity Plan”), replacing the Shore Bancshares, Inc. 2006 Stock and Incentive Plan (“2006 Equity Plan”), which expired on that date. The Company may issue shares of common stock or grant other equity-based awards pursuant to the 2016 Equity Plan. Stock-based awards granted to date generally are time-based, vest in equal installments on each anniversary of the grant date and range over a one - to five -year period of time, and, in the case of stock options, expire 10 years from the grant date. As part of the 2016 Equity Plan, a performance equity incentive award program, known as the “Long-term incentive plan” allows participating officers of the Company to earn incentive awards of performance share/restricted stock units if certain pre-determined targets are achieved at the end of a three-year performance cycle. Stock-based compensation expense based on the grant date fair value is recognized ratably over the requisite service period for all awards and reflects forfeitures as they occur. The 2016 Equity Plan originally reserved 750,000 shares of common stock for grant, and 665,745 shares remained available for grant at March 31, 2018.  The following tables provide information on stock-based compensation expense for the three months ended March 31, 2018 and 2017 .    For Three Months Ended  March 31,  (Dollars in thousands) 2018 2017  Stock-based compensation expense $ 143 $ 418  Excess tax benefits related to stock-based  compensation 135 2    As of  March 31,  (Dollars in thousands) 2018 2017  Unrecognized stock-based compensation  expense $ 871 $ 345  Weighted average period unrecognized  expense is expected to be recognized 1.5 years 0.1 years The following table summarizes restricted stock award activity for the Company under the 2016 Equity Plan for the three months ended March 31, 2018 .

Restricted stock units (RSUs) are similar to restricted stock, except the recipient does not receive the stock immediately, but instead receives it upon the terms and conditions of the Company’s long-term incentive plans which are subject to performance milestones achieved at the end of a three-year period. Each RSU cliff vests at the end of the three -year period and entitles the recipient to receive one share of common stock on a specified issuance date. The recipient does not have any stockholder rights, including voting rights, with respect to the shares underlying awarded RSUs until the recipient becomes the holder of those shares.  During 2018, the Company entered into a long-term incentive program agreement with officers of the Company and its subsidiaries to award RSUs based on a performance metric to be achieved as of December 31, 2020. Assuming the performance metric is achieved, these awards will cliff vest on this date, in which the final number of common shares to be issued will be determined. The range of RSUs which could potentially be awarded at the end of the performance cycle is between 13,188 shares and 52,769 shares, assuming a certain performance metric is met. The table below presents management’s evaluation of the probable number of common stock awards to be issued at the end of the performance cycle.  During 2017, the Company entered into a long-term incentive program agreement with officers of the Company and its subsidiaries to award RSUs based on a performance metric to be achieved as of December 31, 2019. Assuming the performance metric is achieved, these awards will cliff vest on this date, in which the final number of common shares to be issued will be determined. The range of RSUs which could potentially be awarded at the end of the performance cycle is between 12,703 shares and 50,830 shares, assuming a certain performance metric is met. The table below presents management’s evaluation of the probable number of common stock awards to be issued at the end of the performance cycle.  During 2016, the Company entered into a long-term incentive program agreement with officers of the Company and its subsidiaries to award RSUs based on a performance metric to be achieved as of December 31, 2018. Assuming the performance metric is achieved, t hese awards will cliff vest on this date, in which the final number of common shares to be issued will be determined. The range of RSUs which could potentially be awarded at the end of the performance cycle is between 12,214 shares and 48,871 shares, assuming a certain performance metric is met. In addition, two members of the long-term incentive plan from 2015 forfeited their RSUs due to leaving the Company before the end of the vesting period. The table below presents management’s evaluation of the probable number of common stock awards to be issued at the end of the performance cycle.  The following table summarizes restricted stock units activity based on management’s evaluation of the probable number of common stock awards to be issued at the end of the performance cycle for the Company under the 2016 Equity Plan for the three months ended March 31, 2018.

The following table summarizes stock option activity for the Company under the 2016 Equity Plan for the three months ended March 31, 2018 .

The weighted average fair value of stock options granted during the three months ended March 31, 2017 was $10.99 . The Company estimates the fair value of options using the Black-Scholes valuation model with weighted average assumptions for dividend yield, expected volatility, risk-free interest rate and expected lives (in years). The expected dividend yield is calculated by dividing the total expected annual dividend payout by the average stock price. The expected volatility is based on historical volatility of the underlying securities. The risk-free interest rate is based on the Federal Reserve Bank’s constant maturities daily interest rate in effect at grant date. The expected contract life of the options represents the period of time that the Company expects the awards to be outstanding based on historical experience with similar awards. The following weighted average assumptions were used as inputs to the Black-Scholes valuation model for options granted in 2017 .      2017  Dividend yield 0.84 %  Expected volatility 64.80 %  Risk-free interest rate 2.42 %  Expected contract life (in years) 10 years  At the end of the first quarter of 2018 , the aggregate intrinsic value of the options outstanding under the 2016 Equity Plan was $250 thousand based on the $18.86 market value per share of the Company’s common stock at March 31, 2018 . Similarly, the aggregate intrinsic value of the options exercisable was $250 thousand at March 31, 2018 . The intrinsic value on options exercised during the three months ended March 31, 2018 was $365 thousand based on the $17.92 market value per share of the Company’s common stock at January 31, 2018. The intrinsic value on options exercised in 2017 was $8 thousand based on the $15.89 market value per share of the Company’s common stock at January 30, 2017. At March 31, 2018 , the weighted average remaining contract life of options outstanding was 7.1 years.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 11 – Fair Value Measurements Accounting guidance under GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This accounting guidance also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, loans held for sale and other real estate owned (foreclosed assets). These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets.  Under fair value accounting guidance, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine their fair values. These hierarchy levels are: Level 1 inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Level 2 inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Below is a discussion on the Company’s assets measured at fair value on a recurring basis. Investment Securities Available for Sale Fair value measurement for investment securities available for sale is based on quoted prices from an independent pricing service. The fair value measurements consider observable data that may include present value of future cash flows, prepayment assumptions, credit loss assumptions and other factors. The Company classifies its investments in U.S. Treasury securities , if any, as Level 1 in the fair value hierarchy, and it classifies its investments in U.S. Government agencies securities and mortgage-backed securities issued or guaranteed by U.S. Government sponsored entities as Level 2.     Equity Securities Fair value measurement for equity securities is based on quoted market prices retrieved by the Company via on-line resources. Although these securities have readily available fair market values, the Company deems that they be classified as level 2 investments in the fair value hierarchy due to not being considered traded in a highly active market.  The tables below present the recorded amount of assets measured at fair value on a recurring basis at March 31, 2018 and December 31, 2017 . No assets were transferred from one hierarchy level to another during the first three months of 2018 or 2017 .

Impaired Loans Loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loan impairment is measured using the present value of expected cash flows, the loan’s observable market price or the fair value of the collateral (less selling costs) if the loans are collateral dependent and these are considered Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable. The value of business equipment, inventory and accounts receivable, discounted on management’s review and analysis. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and the client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the factors identified above. Valuation techniques are consistent with those techniques applied in prior periods. Other Real Estate Owned (Foreclosed Assets) Foreclosed assets are adjusted for fair value upon transfer of loans to foreclosed assets. Subsequently, foreclosed assets are carried at the lower of carrying value and fair value. The estimated fair value for foreclosed assets included in Level 3 are determined by independent market based appraisals and other available market information, less costs to sell, that may be reduced further based on market expectations or an executed sales agreement. If the fair value of the collateral deteriorates subsequent to the initial recognition, the Company records the foreclosed asset as a non-recurring Level 3 adjustment. Valuation techniques are consistent with those techniques applied in prior periods.   The tables below present the recorded amount of assets measured at fair value on a nonrecurring basis at March 31, 2018 and December 31, 2017 .

Financial Instruments With Off Balance Sheet Risk Disclosure [Abstract]
Financial Instruments with Off-Balance Sheet Risk	 Note 12 – Financial Instruments with Off-Balance Sheet Risk  In the normal course of business, to meet the financial needs of its customers, the Bank is a party to financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Letters of credit and other commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the letters of credit and commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The following table provides information on commitments outstanding at March 31, 2018 and December 31, 2017 .

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 1 4 – Revenue Recognition Not On January 1, 2018, the Company adopted ASU No. 2014-09 “Revenue from Contracts with Customers” (Topic 606) and all subsequent ASUs that modified Topic 606. The implementation of the new standard did not have a material impact on the measurement or recognition of revenue; as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts were not adjusted and continue to be reported in accordance with our historic accounting under Topic 605.  Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. However, the recognition of these revenue streams did not change significantly upon adoption of Topic 606. Substantially all of the Company’s revenue is generated from contracts with customers. Noninterest revenue streams in-scope of Topic 606 are discussed below. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or at the end of the month through a direct charge to customers’ accounts. Trust and Investment Fee Income Trust and investment fee income are primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Insurance Agency Commissions Insurance income primarily consists of commissions received on insurance premiums from customer policies. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the insurance policy. Shortly after the policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue. The Company does not earn a significant amount of trailer fees on individual insurance policies. Other Noninterest Income Other noninterest income consists of: fees, exchange, other service charges, safety deposit box rental fees, and other miscellaneous revenue streams. Fees and other service charges are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that rentals and renewals of safe deposit boxes will be recognized on a monthly basis consistent with the duration of the performance obligation. The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2018 and 2017.    For Three Months Ended  March 31,  (Dollars in thousands) 2018 2017  Noninterest Income  In-scope of Topic 606:  Service charges on deposit accounts $ 905 $ 834  Trust and investment fee income 400 361  Insurance agency commissions 2,694 2,819  Other noninterest income 873 717  Noninterest Income (in-scope of Topic 606) 4,872 4,731  Noninterest Income (out-of-scope of Topic 606) 57 76  Total Noninterest Income $ 4,929 $ 4,807  Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of March 31, 2018 and December 31, 2017, the Company did not have any significant contract balances.

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, 2018 , the consolidated results of income and comprehensive income for the three months ended March 31, 2018 and 2017 , and changes in stockholders’ equity and cash flows for the three months ended March 31, 2018 and 2017 , have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2017 were derived from the 2017 audited financial statements. The results of operations for the three months ended March 31, 2018 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, 2017 . 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 subsidiaries.
Recent Accounting Standards	Recent Accounting Standards 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 in this ASU are effective for fiscal years after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Leases and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU No. 2016-02 will have on its consolidated financial statements. The Company has put together a team to inventory all leases and accumulate the lease data necessary to apply the amended guidance. 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 held to maturity securities. At this time, the Company has established a project management team which is in the process of developing an adoption process and understanding this pronouncement, evaluating the impact of this pronouncement and researching additional software resources that could assist with the implementation.  ASU No. 2017-04 – In January 2017, FASB issued ASU No. 2017-04, “ Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The ASU simplifies measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The Company should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. The impairment charge is limited to the amount of goodwill allocated to that reporting unit. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for 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. 2017-08 – In March 2017, the FASB issued ASU No. 2017-08, “Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. This guidance shortens the amortization period of certain callable debt securities held at a premium to the earliest call date. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company’s consolidated financial statements.

Award description		The Company may issue shares of common stock or grant other equity-based awards pursuant to the 2016 Equity Plan. Stock-based awards granted to date generally are time-based, vest in equal installments on each anniversary of the grant date and range over a one- to five-year period of time, and, in the case of stock options, expire 10 years from the grant date. As part of the 2016 Equity Plan, a performance equity incentive award program, known as the "Long-term incentive plan" allows participating officers of the Company to earn incentive awards of performance share/restricted stock units if certain pre-determined targets are achieved at the end of a three-year performance cycle. Stock-based compensation expense based on the grant date fair value is recognized ratably over the requisite service period for all awards and reflects forfeitures as they occur.

Award description		Restricted stock units (RSUs) are similar to restricted stock, except the recipient does not receive the stock immediately, but instead receives it upon the terms and conditions of the Company's long-term incentive plans which are subject to performance milestones achieved at the end of a three-year period. Each RSU cliff vests at the end of the three-year period and entitles the recipient to receive one share of common stock on a specified issuance date. The recipient does not have any stockholder rights, including voting rights, with respect to the shares underlying awarded RSUs until the recipient becomes the holder of those shares.During 2018, the Company entered into a long-term incentive program agreement with officers of the Company and its subsidiaries to award RSUs based on a performance metric to be achieved as of December 31, 2020. Assuming the performance metric is achieved, these awards will cliff vest on this date, in which the final number of common shares to be issued will be determined. The range of RSUs which could potentially be awarded at the end of the performance cycle is between 13,188 shares and 52,769 shares, assuming a certain performance metric is met. The table below presents management's evaluation of the probable number of common stock awards to be issued at the end of the performance cycle.During 2017, the Company entered into a long-term incentive program agreement with officers of the Company and its subsidiaries to award RSUs based on a performance metric to be achieved as of December 31, 2019. Assuming the performance metric is achieved, these awards will cliff vest on this date, in which the final number of common shares to be issued will be determined. The range of RSUs which could potentially be awarded at the end of the performance cycle is between 12,703 shares and 50,830 shares, assuming a certain performance metric is met.
