Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of SB One Bancorp, formerly Sussex Bancorp, (“we,” “us,” “our” or the “company”) and our wholly owned subsidiary SB One Bank, formerly Sussex Bank (the “Bank”). The corporate name change was voted and approved during the shareholder meeting on April 25, 2018. The name changes were a part of a larger rebrand effort undertaken by Sussex Bank which merged with Community Bank of Bergen County, NJ earlier this year. The Bank’s wholly owned subsidiaries are SCB Investment Company, Inc., SCBNY Company, Inc., ClassicLake Enterprises, LLC, PPD Holding Company, LLC, Community Investing Company, Inc., and SB One Insurance Agency Inc. ("SB One Insurance Agency"), formerly Tri-State Insurance Agency, Inc., a full service insurance agency located in Sussex County, New Jersey with a satellite office located in Bergen County, New Jersey. SB One Insurance Agency’s operations are considered a separate segment for financial disclosure purposes. All inter-company transactions and balances have been eliminated in consolidation. The Bank operates fourteen banking offices: eight located in Sussex County, New Jersey, four located in Bergen County, New Jersey, one located in Warren County, New Jersey, and one in Queens County, New York. We are subject to the supervision and regulation of the Board of Governors of the Federal Reserve System (the “FRB”). The Bank’s deposits are insured by the Deposit Insurance Fund (“DIF”) of the FDIC up to applicable limits. The operations of the company and the Bank are subject to the supervision and regulation of the FRB, the FDIC and the New Jersey Department of Banking and Insurance (the “Department”) and the operations of SB One Insurance Agency are subject to supervision and regulation by the Department. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for full year financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for the three month periods ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto that are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 . New Accounting Standards In May 2014, the FASB issued an Accounting Standard Update (“ASU”) 2014-09 to amend its guidance on “Revenue from Contracts with Customers, (Topic 606). The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. In August 2015, the FASB issued an amendment (ASU 2015-14) which defers the effective date of this new guidance by one year. More detailed implementation guidance on Topic 606 was issued in March 2016 (ASU 2016-08), April 2016 (ASU 2016-10), May 2016 (ASU 2016-12), December 2016 (ASU 2016-20), February 2017 (ASU 2017-05) and September 2017 (ASU 2017-13), and the effective date and transition requirements for these ASUs are the same as the effective date and transition requirements of ASU 2014-09. The amendments in Topic 606 are effective for public business entities for annual periods beginning after December 15, 2017. Approximately 82% of the Company’s revenue for the quarter ended March 31, 2018, was comprised of interest income on financial assets, which are explicitly excluded from the scope of Topic 606. With respect to our non-interest income, management has identified revenue streams within the scope of the guidance, primarily service fees on deposits, ATM and debit card fees and insurance commissions and fees which are discussed below. Topic 606 states that revenue should be recognized when the entity satisfies a performance obligation by transferring goods or services to the customer. An asset is considered transferred when the customer obtains control of the asset and is able to use and obtain substantially all of the benefits of the asset. The entity then has to determine whether the performance obligation was satisfied over time or at a point in time to determine when to recognize revenue. The Company determined based on the criteria presented in Topic 606 that the performance obligations were satisfied at a point in time since the customer obtains immediate control of the deposit accounts, ATM/Debit Card and insurance policy and there are no additional obligations that the Company performs over time; therefore, the revenue would be recognized as received. The Company recognized $328 thousand in income for Service fees on deposit accounts and $1.9 million in insurance commissions and fees for the three months ended March 31, 2018. The Company currently presents the revenue and associated costs on a gross basis. ASU 2014-09 and related amendments were adopted effective January 1, 2018, using the cumulative effect approach. Under this alternative, the Company applied the new revenue standard only to contracts that were incomplete under legacy U.S. GAAP at the date of initial application and evaluated the cumulative effect of the new standard as a potential adjustment to the opening balance of retained earnings. The Company`s adoption of the ASU on January 1, 2018 did not significantly change the recognition of revenue on the Company's consolidated financial statements and, as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Service fees on deposit accounts represent account analysis fees, monthly service fees, check ordering fees and other deposit related fees. Revenue is recognized when the performance obligation is completed, which is generally monthly for account maintenance services or when a transaction has been completed. Insurance commissions and fees represent insurance policies that our insurance agency, SB One Insurance Agency, arranges between the policy holder and the related insurance agency. SB One Insurance Agency acts solely as an insurance broker that provides the service of connection between a policy holder and carrier. SB One Insurance Agency’s performance obligation is satisfied once the policy becomes active therefore no other performance obligation is required. Revenues for the commissions to SB One Insurance Agency’s insurance contracts will generally be recognized as of the effective date of the insurance policy or the date on which the policy premium is processed into our systems, whichever is later. Commission revenues related to installment billings are recognized on the latter of effective or invoiced date. Subsequent commission adjustments are recognized upon our receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when we receive formal notification of the amount of such payments. The Company recognized $213 thousand in ATM and debit card fees. ATM and debit card fees are primarily comprised of debit and credit card income (interchange fees), 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 our card payment network. The Company currently presents the revenue and associated costs with debit and credit card income on a net basis. 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, agency fee income, and other services. The Company’s performance obligation for fees 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 within one month. Under Topic 606, 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. In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost. In January 2016, FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01, 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. In addition, the amendments in this ASU require an entity to disclose the fair value of its financial instruments using the exit price notion. Exit price is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For public entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company has updated the fair value disclosure on Note 12 Fair Value of Financial Instruments in this report to reflect adoption of this standard, to include using the exit price notion in the fair value disclosure of financial instruments. The Company`s adoption of the ASU did not have a significant impact on the Company's consolidated financial statements. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted for all public business entities 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 Company currently expects that upon adoption of ASU 2016-02, right-of-use assets and lease liabilities will be recognized in the consolidated balance sheet in amounts that will be material; however, there will be no material impact on operations. In June, 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326) (the “ASU”), which introduces new guidance for the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale (AFS) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The ASU will be effective for public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All other entities will have one additional year. Early application of the guidance will be permitted for all entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. The Company has taken steps to prepare for implementation when it becomes effective, such as evaluating the potential use of outside professionals for an updated model. In August 2016, FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force), which addresses eight classification issues related to the statement of cash flows: (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon bonds, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the ASU in an interim period, 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. Entities should apply this ASU using a retrospective transition method to each period presented. If it is impracticable for an entity to apply the ASU retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. The Company`s adoption of the ASU did not have a significant impact on the Company's consolidated financial statements. In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). The main objective of this ASU is to simplify the accounting for goodwill impairment by requiring impairment charges be based upon the first step in the current two-step impairment test under Accounting Standards Codification (ASC) 350. Currently, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). This ASU’s objective is to simplify how all entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the impact of the pending adoption on its consolidated financial statements. In March 2017, FASB issued ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities (Subtopic 310-20). The update shortens the amortization period for premiums on purchased callable debt securities to the earliest call date. The amendment will apply only to callable debt securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates, apply to all premiums on callable debt securities, regardless of how they were generated, and require companies to reset the effective yield using the payment terms of the debt security if the call option is not exercised on the earliest call date. The ASU does not require an accounting change for securities held at a discount. The discount continues to be amortized to maturity and does not apply when the investor has already incorporated prepayments into the calculation of its effective yield under other GAAP. The amendments in the ASU are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted, including adoption in an interim 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. The Company's adoption of the ASU will not have a significant impact on the Company's consolidated financial statements. In August 2017, FASB issued ASU 2017-12 Derivatives and Hedging (Topic 815). The objective of the ASU is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and to make improvements to simplify the application of hedge accounting guidance in current GAAP. The amendments in the ASU will, among other things, 1) permit hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risks; 2) change the guidance for designating fair value hedges of interest rate risk and for measuring the change in fair value of the hedged item in fair value hedges of interest rate risk; 3) modify disclosures to include a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges; and 4) eliminate the requirement to disclose the ineffective portion of the change in fair value of hedging instruments. These changes will more closely align the results of cash flow and fair value hedge accounting with risk management activities and the presentation of hedge results in the financial statements. ASU 2017-12 will be effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For all other entities, the ASU will be effective for fiscal years beginning after December 15, 2019 and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted in any interim period after issuance of the update with all transition requirements and elections being applied to hedging relationships existing on the date of adoption. The Company's adoption of the ASU will not have a significant impact on the Company's consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS On January 4, 2018 the Company announced the successful closing of the merger with Community Bank of Bergen County, NJ, a New Jersey-chartered bank (“Community”) in an all-stock transaction (the “Merger”). Under the terms of the agreement, Community merged with and into SB One Bank, with SB One Bank being the surviving entity and each outstanding share of Community common stock was exchanged for 0.97 shares of SB One Bancorp's common stock. The Company issued 1,873,028 shares of its common stock, having an aggregate fair value of $51.9 million in the merger and paid approximately $2 thousand in cash for fractional shares. Outstanding Community stock options were paid out in cash for a total payment of $140 thousand . The acquisition was accounted for under the acquisition method of accounting. Accordingly, the assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values based on management's best estimate using information available at the date of the acquisition, including the use of a third party valuation specialist. The following table summarized the estimated fair value of the acquired assets and liabilities assumed at the date of acquisition for Community. (Dollars in thousands) January 4, 2018 Cash and cash equivalents $ 6,693 Interest bearing time deposits with other banks 100 Securities available for sale 75,909 Federal Home Loan Bank Stock 905 Loans 236,070 Foreclosed real estate 1,376 Premises and equipment, net 10,612 Accrued interest receivable 824 Goodwill 22,018 Intangibles assets 1,331 Bank-owned life insurance 7,963 Other assets 1,838 Total Assets $ 365,639 Deposits $ (301,157 ) Borrowings (12,000 ) Other liabilities (599 ) Total Liabilities $ (313,756 ) Net assets acquired $ 51,883 The Core deposit intangible totaled $1.3 million and is being amortized over its estimated useful life of approximately 10 years using an accelerated method. The goodwill will be evaluated annually for impairment. The goodwill is not deductible for tax purposes. The fair values of deposit liabilities with no stated maturities such as checking, money market and savings accounts, were assumed to equal the carrying amounts since these deposits are payable on demand. The fair values of certificates of deposits and IRAs represent the present value of contractual cash flows discounted at market rates for similar certificates of deposit. Fair values of the major categories of assets acquired and liabilities assumed were determined as follows: Investment securities available-for-sale The estimated fair values of the investment securities available for sale, primarily comprised of U.S. Government agency mortgage-backed securities, U.S. government agencies and municipal bonds, were determined using open market pricing provided by multiple independent securities brokers. Management reviewed the open market quotes used in pricing the securities. A fair value discount of $261,000 was recorded on the investments. Loans Loans acquired in the Community acquisition were recorded at fair value, and there was no carryover related allowance for loan and lease losses. The fair values of loans acquired from Community were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted for estimated future credit losses and the rate of prepayments. Projected cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. The fair value of the acquired loans receivable had a gross amortized cost basis of $242,471,000 . The table below illustrates the fair value adjustments made to the amortized cost basis in order to present a fair value of the loans acquired. The credit adjustment on purchased credit impaired loans is derived in accordance with ASC 310-30 and represents the portion of the loan balances that has been deemed uncollectible based on the Company’s expectations of future cash flows for each respective loan. (Dollars in thousands) Gross amortized cost basis at January 4, 2018 $ 242,471 Interest rate fair value adjustment on general pooled loans 324 Credit fair value adjustment on general pooled loans (4,061 ) Credit fair value adjustment on purchased credit impaired loans (2,664 ) Fair value of acquired loans at January 4, 2018 $ 236,070 For loans acquired without evidence of credit quality deterioration, the Company prepared the interest rate loan fair value and credit fair value adjustments. Loans were grouped into general pools by characteristics such as loan type, term, collateral and rate. Market rates for similar loans were obtained from various internal and external data sources and reviewed by management for reasonableness. The average of these rates was used as the fair value interest rate a market participant would utilize. A present value approach was utilized to calculate the interest rate fair value premium of $324,000 . Additionally for loans acquired without credit deterioration, a credit fair value adjustment was calculated using a two-part credit fair value analysis: 1) expected lifetime credit migration losses; and 2) estimated fair value adjustment for certain qualitative factors. The expected lifetime losses were calculated using historical losses observed at the Bank, Community and peer banks. The Company also estimated an environmental factor to apply to each loan type. The environmental factor represents potential discount which may arise due to general credit and economic factors. A credit fair value discount of $4.1 million was determined. Both the interest rate and credit fair value adjustments relate to loans acquired with evidence of credit quality deterioration will be substantially recognized as interest income on a level yield amortization method over the expected life of the loans. The following is a summary of the loans accounted for in accordance with ASC 310-30 that were acquired in the Community acquisition as of the closing date. (Dollars in thousands) Acquired Credit Impaired Loans Contractually required principal and interest at acquisition $ 6,289 Contractual cash flows not expected to be collected (non-accretable difference) 1,819 Expected cash flows at acquisition 4,470 Interest component of expected cash flows (accretable difference) 846 Fair value of acquired loans $ 3,624 Bank Premises The Company acquired three branches of Community, all of which were owned by Community. The fair value of Community’s premises was determined based upon independent third-party appraisals performed by licensed appraisers in the market in which the premises are located. Core Deposit Intangible The fair value of the core deposit intangible was determined based on a discounted cash flow analysis using a discount rate commensurate with market participants. To calculate cash flows, deposit account servicing costs (net of deposit fee income) and interest expense on deposits were compared to the cost of alternative funding sources available through national brokered CD offering rates. The projected cash flows were developed using projected deposit attrition rates. The core deposit intangible will be amortized over ten years using the sum-of-years digits method. Time Deposits The fair value adjustment for time deposits represents a discount from the value of the contractual repayments of fixed-maturity deposits using prevailing market interest rates for similar-term time deposits. The time deposit discount of approximately $964,500 is being amortized into income on a level yield amortization method over the contractual life of the deposits. Bank Owned Life Insurance Community's bank-owned life insurance book value was $8.0 million with no fair value adjustment. The following table presents certain pro forma information as if Community had been acquired on January 1, 2017. These results combine the historical results of the Company in the Company’s Consolidated Statements of Income and, while certain adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, they are not indicative of what would have occurred had the acquisition taken place on January 1, 2017. In particular, no adjustments have been made to eliminate the amount of Community’s provision for loan losses that would not have been necessary had the acquired loans been recorded at fair value as of January 1, 2017. The Corporation expects to achieve further operating cost savings and other business synergies as a result of the acquisition which are not reflected in the pro forma amounts below: (Dollars in thousands) For the Year Ended December 31, 2017 Total revenues (net interest income plus noninterest income) $ 47,280 Net Income 6,257

As of March 31, 2018 , we reviewed our available for sale securities portfolio for indications of impairment. This review included analyzing the length of time and the extent to which the fair value was lower than the cost, the financial condition and near-term prospects of the issuer, including any specific events which may influence the operations of the issuer and the intent and likelihood of selling the security. The intent and likelihood of sale of debt and equity securities are evaluated based upon our investment strategy for the particular type of security and our cash flow needs, liquidity position, capital adequacy and interest rate risk position. U.S. Government Agencies At March 31, 2018 and December 31, 2017 , the declines in fair value and the unrealized losses for our U.S. government agencies securities were primarily due to changes in spreads and market conditions and not credit quality. At March 31, 2018 , there were twelve securities with a fair value of $17.0 million that had an unrealized loss that amounted to $89 thousand . As of March 31, 2018 , we did not intend to sell and it was not more-likely-than-not that we would be required to sell any of these securities before recovery of their amortized cost basis. Therefore, none of the U.S. government agency securities at March 31, 2018 were deemed to be other-than-temporarily impaired (“OTTI”). At December 31, 2017 , there were three securities with a fair value of $5.3 million that had an unrealized loss that amounted to $28 thousand . U.S. Government Sponsored Agencies At March 31, 2018 and December 31, 2017, the decline in fair value and the unrealized losses for our U.S. government sponsored agencies securities were primarily due to changes in spreads and market conditions and not credit quality. At March 31, 2018, there were five securities with a fair value of $11.0 million that had an unrealized loss that amounted to $54 thousand . As of March 31, 2018, we did not intend to sell and it was not more-likely-than-not that we would be required to sell any of these securities before recovery of their amortized cost basis. Therefore, none of the U.S. government sponsored agency securities at March 31, 2018, were deemed to be OTTI. At December 31, 2017, there were two securities with a fair value of $3.5 million that had an unrealized loss that amounted to $1 thousand . State and Political Subdivisions At March 31, 2018 and December 31, 2017 , the decline in fair value and the unrealized losses for our state and political subdivisions securities were caused by changes in interest rates and spreads and were not the result of credit quality. At March 31, 2018, there were twenty-nine securities with a fair value of $31.6 million that had an unrealized loss that amounted to $761 thousand . These securities typically have maturity dates greater than 10 years and the fair values are more sensitive to changes in market interest rates. At December 31, 2017 , there were nine securities with a fair value of $8.9 million that had an unrealized loss that amounted to $132 thousand . Mortgage-Backed Securities At March 31, 2018 and December 31, 2017 , the decline in fair value and the unrealized losses for our mortgage-backed securities guaranteed by U.S. government-sponsored enterprises were primarily due to changes in spreads and market conditions and not credit quality. At March 31, 2018 , there were thirty-six securities with a fair value of $58.4 million that had an unrealized loss that amounted to $1.3 million . As of March 31, 2018 , we did not intend to sell and it was not more-likely-than-not that we would be required to sell any of these securities before recovery of their amortized cost basis. Therefore, none of our mortgage-backed securities at March 31, 2018 were deemed to be OTTI. At December 31, 2017 , there were sixteen securities with a fair value of $21.3 million that had an unrealized loss that amounted to $479 thousand . Corporate Debt At March 31, 2018 , there were no securities that had an unrealized loss. These securities typically have maturity dates greater than 5 years and the fair values are more sensitive to changes in market interest rates. As of March 31, 2018 , we did not intend to sell and it was more-likely-than-no that we would be required to sell any of these securities before recovery of their amortized cost basis. Therefore, none of our corporate debt as March 31, 2018, were deemed to be OTTI. At December 31, 2017, there were no securities with an unrealized loss.

The total amount of loans serviced for the benefit of others was approximately $237 thousand and $239 thousand at March 31, 2018 and December 31, 2017 , respectively. Purchased Credit Impaired Loans The carrying value of loans acquired in the Community acquisition and accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality,” was $3.7 million at March 31, 2018, which was $44 thousand more than the balance at the time of acquisition on January 4, 2018. Under ASC Subtopic 310-30, these loans, referred to as purchased credit impaired (“PCI”) loans, may be aggregated and accounted for as pools of loans if the loans being aggregated have common risk characteristics. The Company elected to account for the loans with evidence of credit deterioration individually rather than aggregate them into pools. The difference between the undiscounted cash flows expected at acquisition and the investment in the acquired loans, or the “accretable yield,” is recognized as interest income utilizing the level-yield method over the life of each loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “non-accretable difference,” are not recognized as a yield adjustment, as a loss accrual or as a valuation allowance. Increases in expected cash flows subsequent to the acquisition are recognized prospectively through an adjustment of the yield on the loans over the remaining life, while decreases in expected cash flows are recognized as impairments through a loss provision and an increase in the allowance for loan and lease losses. Valuation allowances (recognized in the allowance for loan and lease losses) on these impaired loans reflect only losses incurred after the acquisition (representing all cash flows that were expected at acquisition but currently are not expected to be received). The following table presents changes in the accretable yield for PCI loans: (Dollars in thousands) Three months ended March 31, 2018 Accretable yield, beginning balance $ — Acquisition of impaired loans 845 Accretable yield amortized to interest income (76 ) Reclassification from non-accretable difference — Accretable yield, ending balance $ 769 There were no PCI loans in 2017.

The credit review process includes the independent evaluation of the loan officer assigned risk ratings by the Chief Credit Officer and a third party loan review company. Such risk ratings are assigned loss component factors that reflect our loss estimate for each group of loans. It is management’s and the Board of Directors’ responsibility to oversee the lending process to ensure that all credit risks are properly identified, monitored, and controlled, and that loan pricing, terms and other safeguards against non-performance and default are commensurate with the level of risk undertaken and is rated as such based on a risk-rating system. Factors considered in assigning risk ratings and loss component factors include: borrower specific information related to expected future cash flows and operating results, collateral values, financial condition and payment status; levels of and trends in portfolio charge-offs and recoveries; levels in portfolio delinquencies; effects of changes in loan concentrations and observed trends in the economy and other qualitative measurements. Our risk-rating system is consistent with the classification system used by regulatory agencies and with industry practices. Loan classifications of Substandard, Doubtful or Loss are consistent with the regulatory definitions of classified assets. The classification system is as follows: • Pass : This category represents loans performing to contractual terms and conditions and the primary source of repayment is adequate to meet the obligation. We have five categories within the Pass classification depending on strength of repayment sources, collateral values and financial condition of the borrower. • Special Mention : This category represents loans performing to contractual terms and conditions; however the primary source of repayment or the borrower is exhibiting some deterioration or weaknesses in financial condition that could potentially threaten the borrowers’ future ability to repay our loan principal and interest or fees due. • Substandard : This category represents loans that the primary source of repayment has significantly deteriorated or weakened which has or could threaten the borrowers’ ability to make scheduled payments. The weaknesses require close supervision by management and there is a distinct possibility that we could sustain some loss if the deficiencies are not corrected. Such weaknesses could jeopardize the timely and ultimate collection of our loan principal and interest or fees due. Loss may not be expected or evident, however, loan repayment is inadequately supported by current financial information or pledged collateral. • Doubtfu l: Loans so classified have all the inherent weaknesses of a substandard loan with the added provision that collection or liquidation in full is highly questionable and not reasonably assured. The probability of at least partial loss is high, but extraneous factors might strengthen the asset to prevent loss. The validity of the extraneous factors must be continuously monitored. Once these factors are questionable the loan should be considered for full or partial charge-off. • Loss : Loans so classified are considered uncollectible, and of such little value that their continuance as active assets is not warranted. Such loans are fully charged off. The following tables illustrate our corporate credit risk profile by creditworthiness category as of March 31, 2018 and December 31, 2017 : ໿ ໿ (Dollars in thousands) Pass Special Mention Substandard Doubtful Total March 31, 2018 Commercial and industrial $ 55,834 $ 478 $ 729 $ — $ 57,041 Construction 57,230 140 105 — 57,475 Commercial real estate 630,560 11,033 13,645 — 655,238 Residential real estate 308,460 477 8,503 — 317,440 Consumer and other 1,992 — 236 — 2,228  $ 1,054,076 $ 12,128 $ 23,218 $ — $ 1,089,422 December 31, 2017 Commercial and industrial $ 54,405 $ 189 $ 165 $ — $ 54,759 Construction 42,379 105 — — 42,484 Commercial real estate 537,636 3,508 10,301 — 551,445 Residential real estate 169,395 228 2,221 — 171,844 Consumer and other 1,130 — — — 1,130  $ 804,945 $ 4,030 $ 12,687 $ — $ 821,662 The following table reflects information about our impaired loans, excluding PCI loans, by class as of March 31, 2018 and December 31, 2017 :  March 31, 2018 December 31, 2017 (Dollars in thousands) Recorded Investment Unpaid Principal Balance Related Allowance Recorded Investment Unpaid Principal Balance Related Allowance  With no related allowance recorded: Commercial and industrial $ — $ 10 $ — $ 20 $ 20 $ — Construction 105 105 — — — — Commercial real estate 3,908 4,232 — 3,834 4,158 — Residential real estate 3,061 3,105 — 1,844 1,877 — With an allowance recorded: Commercial and industrial — — — — — — Commercial real estate 930 1,393 29 929 1,392 28 Residential real estate — — — 220 223 10 Total: Commercial and industrial — 10 — 20 20 — Construction 105 105 — — — — Commercial real estate 4,838 5,625 29 4,763 5,550 28 Residential real estate 3,061 3,105 — 2,064 2,100 10  $ 8,004 $ 8,845 $ 29 $ 6,847 $ 7,670 $ 38 ໿ The following table presents the average recorded investment and income recognized for our impaired loans, excluding PCI loans, for the three months ended March 31, 2018 and 2017 :  For the Three Months Ended March 31, 2018 For the Three Months Ended March 31, 2017 (Dollars in thousands) Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized With no related allowance recorded: Commercial and industrial $ 10 $ — $ 19 $ — Construction 53 — — — Commercial real estate 3,871 12 2,308 — Residential real estate 2,453 11 1,525 1 Total impaired loans without a related allowance 6,387 23 3,852 1  With an allowance recorded: Commercial real estate 930 — 2,142 8 Residential real estate 110 — 316 — Total impaired loans with an allowance 1,040 — 2,465 8 Total impaired loans $ 7,427 $ 23 $ 6,317 $ 9 We recognize interest income on performing impaired loans as payments are received. On non-performing impaired loans we do not recognize interest income as all payments are recorded as a reduction of principal on such loans. Impaired loans include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, postponement or forgiveness of principal, forbearance or other actions intended to maximize collection. The concessions rarely result in the forgiveness of principal or accrued interest. In addition, we attempt to obtain additional collateral or guarantor support when modifying such loans. Non-accruing restructured loans may be returned to accrual status when there has been a sustained period of repayment performance (generally six consecutive months of payments) and both principal and interest are deemed collectible. The following table presents the recorded investment in troubled debt restructured loans, based on payment performance status: (Dollars in thousands) Commercial Real Estate Residential Real Estate Total March 31, 2018 Performing $ 656 $ 1,477 $ 2,133 Non-performing 2,522 373 2,895 Total $ 3,178 $ 1,850 $ 5,028 December 31, 2017 Performing $ 449 $ 483 $ 932 Non-performing 1,594 242 1,836 Total $ 2,043 $ 725 $ 2,768 Troubled debt restructured loans are considered impaired and are included in the previous impaired loans disclosures in this footnote. As of March 31, 2018 , we have not committed to lend additional amounts to customers with outstanding loans that are classified as troubled debt restructuring. There was no troubled debt restructuring that occurred during the three months ended March 31, 2018 and 2017. The increase in troubled debt restructured loans was due to loans acquired in the Community acquisition. There was one troubled debt restructuring with an outstanding balance of $127 thousand for which there was a payment default within twelve months following the date of the restructuring for the three months ended March 31, 2018 . There was no troubled debt restructuring for which there was a payment default within twelve months following the date of the restructuring for the three months ended March 31, 2017 . We may obtain physical possession of residential real estate collateralizing a consumer mortgage loan via foreclosure on an in-substance repossession. As of March 31, 2018 , we had five foreclosed residential real estate properties with a carrying value of $1.3 million . As of December 31, 2017, we had one foreclosed residential real estate property with a carrying value of $179 thousand . In addition, as of March 31, 2018 and December 31, 2017 , respectively, we had consumer loans with a carrying value of $1.2 million and $180 thousand collateralized by residential real estate property for which formal foreclosure proceedings were in process. The increases in amounts at March 31, 2018, compared to December 31, 2017, were due to loans acquired in the Community acquisition.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share are calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares (unvested restricted stock grants and stock options) had been issued, as well as any adjustment to income that would result from the assumed issuance of potential common shares that may be issued by us. Potential common shares related to stock options are determined using the treasury stock method.

Comprehensive Income [Abstract]
Other Comprehensive Income	OTHER COMPREHENSIVE INCOME Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. The components of other comprehensive income, both before tax and net of tax, are as follows: ໿  Three Months Ended March 31, 2018 Three Months Ended March 31, 2017  Before Tax Tax Effect Net of Tax Before Tax Tax Effect Net of Tax (Dollars in thousands) Other comprehensive income (loss): Unrealized gains on available for sale securities $ (2,167 ) $ (588 ) $ (1,579 ) $ 676 $ 270 $ 406 Fair value adjustments on derivatives 1,107 311 796 40 16 24 Reclassification adjustment for net losses (gains) on securities transactions included in net income — — — (107 ) (42 ) (65 ) Total other comprehensive (loss) income $ (1,060 ) $ (277 ) $ (783 ) $ 609 $ 244 $ 365

Goodwill and Other Intangibles	GOODWILL AND OTHER INTANGIBLES The Company had goodwill of $24.8 million and $2.8 million for the periods ended March 31, 2018 and December 31, 2017, respectively. The increase was due to the merger with Community Bank with total goodwill amounting to $22.0 million . The Company reviews its goodwill and intangible assets annually, on September 30, or more frequently if conditions warrant, for impairment. In testing goodwill for impairment, the Company compares the estimated fair value of its reporting unit to its carrying amount, including goodwill. The Company recorded a core deposit intangible of $1.3 million for the Community Bank acquisition. For the period ended March 31, 2018, the Company amortized $61 thousand in core deposit intangible. The estimated future amortization expense for the remainder of 2018 and for each of the succeeding five years ended December 31 is as follows (dollars in thousands): For the Year Ended Amortization Expense 2018 $ 182 2019 217 2020 194 2021 169 2022 145 2023 121

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION We currently have stock-based compensation plans in place for our directors, officers, employees, consultants and advisors. Under the terms of these plans we may grant restricted shares and stock options for the purchase of our common stock. The stock-based compensation is granted under terms determined by our Compensation Committee. Our standard stock option grants have a maximum ter m of 10 years, generally vest over periods ranging between one and five years , and are granted with an exercise price equal to the fair market value of the common stock on the date of grant. Restricted stock is valued at the market value of the common stock on the date of grant and generally vests over periods of three to five years . All dividends paid on restricted stock, whether vested or unvested, are paid to the shareholder. Information regarding our stock option plans for the six months ended March 31, 2018 is as follows:  Number of Shares Weighted Average Exercise Price per Share Weighted Average Contractual Term Aggregate Intrinsic Value Options outstanding, beginning of year 69,123 $ 11.10 Options outstanding, end of quarter 69,123 $ 11.10 7.1 $ 1,334,151 Options exercisable, end of quarter 36,229 $ 10.85 7.0 $ 708,336 Option price range at end of quarter $9.97 to $12.83 Option price of exercisable shares $9.97 to $12.83 ໿ During the three months ended March 31, 2018 and 2017 , we expensed $12 thousand and $12 thousand , respectively, in stock-based compensation under stock option awards. There were no options granted during the three months ended March 31, 2018 and 2017. Expected future expense relating to the unvested options outstanding as of March 31, 2018 is $104 thousand over a weighted average period of 2.1 years. Upon exercise of vested options, management expects to draw on treasury stock as the source of the shares. The summary of changes in unvested restricted stock awards for the three months ended March 31, 2018 , is as follows:  Number of Shares Weighted Average Grant Date Fair Value Unvested restricted stock, beginning of year 85,761 $ 18.34 Granted 20,169 29.15 Forfeited (4,148 ) 17.66 Vested (29,145 ) 16.15 Unvested restricted stock, end of period 72,637 $ 22.25 During the three months ended March 31, 2018 and 2017 , we expensed $153 thousand and $153 thousand , respectively, in stock-based compensation under restricted stock awards. At March 31, 2018 , unrecognized compensation expense for unvested restricted stock was $1.4 million , which is expected to be recognized over an average period of 2.5 years.

Guarantees

Guarantees	3 Months Ended
	Mar. 31, 2018
Guarantees [Abstract]
Guarantees	GUARANTEES We do not issue any guarantees that would require liability recognition or disclosure, other than standby letters of credit. Standby letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party. Generally, all letters of credit, when issued, have expiration dates within one year . The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Generally, we hold collateral and/or personal guarantees supporting these commitments. As of March 31, 2018 , we had $1.7 million of outstanding letters of credit. Management believes that the proceeds obtained through a liquidation of collateral and the enforcement of guarantees would be sufficient to cover the potential amount of future payments required under the corresponding guarantees. The amount of the liability as of March 31, 2018 , for guarantees under standby letters of credit issued is not material.

Fair Value Of Financial Instrum

Fair Value Of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS Management uses its best judgment in estimating the fair value of our financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts we could have realized in a sale transaction on the dates indicated. The fair value amounts have been measured as of their respective period ends, and have not been re-evaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end. In accordance with U.S. GAAP, we use a hierarchical disclosure framework associated with the level of pricing observability utilized in measuring assets and liabilities at fair value. The three broad levels defined by the hierarchy are as follows: • Level I - Quoted prices are available in active markets for identical assets or liabilities as of the reported date. • Level II - Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these asset and liabilities include items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed. • Level III - Assets and liabilities that have little to no pricing observability as of reported date. These items do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. The following table summarizes the fair value of our financial assets measured on a recurring basis by the above pricing observability levels as of March 31, 2018 and December 31, 2017 : ໿ ໿ (Dollars in thousands) Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level I) Significant Other Observable Inputs (Level II) Significant Unobservable Inputs (Level III) March 31, 2018 U.S. government agencies $ 29,902 $ — $ 29,902 $ — U.S. government-sponsored enterprises 15,982 — 15,982 — State and political subdivisions 60,948 — 60,948 — Mortgage-backed securities - U.S. government-sponsored enterprises 65,221 — 65,221 — Corporate debt 2,048 — 2,048 — Derivative instruments Interest rate swaps 2,558 — 2,558 — December 31, 2017 U.S. government agencies $ 18,861 $ — $ 18,861 $ — U.S. government-sponsored enterprises 6,061 — 6,061 — State and political subdivisions 41,234 — 41,234 — Mortgage-backed securities - U.S. government-sponsored enterprises 30,544 — 30,544 — Corporate debt 2,030 — 2,030 — Derivative instruments Interest rate swaps 1,451 — 1,451 — Our available for sale and held to maturity securities portfolios contain investments, which were all rated within our investment policy guidelines at time of purchase, and upon review of the entire portfolio all securities are marketable and have observable pricing inputs. For financial assets measured at fair value on a nonrecurring basis, the fair value measurements by level within the fair value hierarchy used at March 31, 2018 and December 31, 2017 are as follows: ໿ (Dollars in thousands) Fair Value Measurements Quoted Prices in Active Markets for Identical Assets (Level I) Significant Other Observable Inputs (Level II) Significant Unobservable Inputs (Level III) March 31, 2018 Impaired loans $ 111 $ — $ — $ 111 Foreclosed real estate 546 — — 546 December 31, 2017 Impaired loans $ 1,794 $ — $ — $ 1,794 Foreclosed real estate 568 — — 568 The following table presents additional qualitative information about assets measured at fair value on a nonrecurring basis and for which Level III inputs were used to determine fair value: ໿  Qualitative Information about Level III Fair Value Measurements (Dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range (Weighted Average) March 31, 2018 Impaired loans $ 111 Appraisal of Appraisal 0% to (-100.0% )  collateral adjustments (1) (-7.32%) Foreclosed real estate 546 Appraisal of Selling  collateral expenses (1) -7.0%(-7.0%) December 31, 2017 Impaired loans $ 1,794 Appraisal of Appraisal 0% to (-100.0% )  collateral adjustments (1) (-0.22%) Foreclosed real estate 568 Appraisal of Selling  collateral expenses (1) -7.0% (-7.0%) (1) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated selling expenses. The range and weighted average of selling expenses and other appraisal adjustments are presented as a percentage of the appraisal. The following information should not be interpreted as an estimate of the fair value of the entire company since a fair value calculation is only provided for a limited portion of our assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between our disclosures and those of other companies may not be meaningful. The following methods and assumptions were used to estimate the fair value of our financial instruments at March 31, 2018 and December 31, 2017 : Cash and Cash Equivalents (Carried at Cost): The carrying amounts reported in the balance sheet for cash and cash equivalents approximate those assets’ fair value. Deposits (Carried at Cost): Fair value for fixed-rate time certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates to a schedule of aggregated expected monthly maturities on time deposits. We generally purchase amounts below the insured limit, limiting the amount of credit risk on these time deposits. Securities: The fair value of securities, available for sale (carried at fair value) and securities held to maturity (carried at amortized cost) are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level I), or matrix pricing (Level II), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices. For certain securities which are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence (Level III). In the absence of such evidence, management’s best estimate is used. Federal Home Loan Bank Stock (Carried at Cost): The carrying amount of restricted investment in bank stock approximates fair value and considers the limited marketability of such securities. Loans Receivable (Carried at Cost): The Company has adopted ASU 2016-01, and therefore is measuring the fair value of loans receivable under the exit price notion rather than the previous method of entry price notion. Under the entry price notion, the fair value estimate of loans receivable was based on discounted cash flow. At March 31, 2018, the exit price notion used to estimate the fair value of loans receivable was based on similar techniques, with the addition of current origination spreads, liquidity premiums, or credit adjustments. Impaired Loans (Carried at Lower of Cost or Fair Value): Fair value of impaired loans is generally determined based upon independent third-party appraisals of the properties, or discounted cash flows based upon the expected proceeds. These assets are included in Level III fair values, based upon the lowest level of input that is significant to the fair value measurements. The fair value of impaired loans totaled $111 thousand and $1.8 million at March 31, 2018 and December 31, 2017 , respectively. These balances consist of loans that were written down or required additional reserves during the periods ended March 31, 2018 and December 31, 2017 , respectively. Deposit Liabilities (Carried at Cost): The fair values disclosed for demand, savings and money market accounts are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market on certificates to a schedule of aggregated expected monthly maturities on time deposits. Borrowings (Carried at Cost): Fair values of Federal Home Loan Bank (“FHLB”) advances are estimated using discounted cash flow analysis, based on quoted prices for new FHLB advances with similar credit risk characteristics, terms and remaining maturity. These prices obtained from this active market represent a market value that is deemed to represent the transfer price if the liability were assumed by a third party. Derivatives (Carried at Fair Value): The Company also uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges, and which satisfy hedge accounting requirements, involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. These derivatives were used to hedge the variable cash outflows associated with FHLB borrowings along with our junior subordinated debenture at U.S. Capital Trust. The effective portion of changes in the fair value of these derivatives are recorded in accumulated other comprehensive income, and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of these derivatives is recognized directly in earnings. The fair value of the Company`s derivatives are determined using discounted cash flow analysis using observable market-based inputs, which are considered Level 2 inputs. Subordinated Debentures (Carried at Cost): Fair values of subordinated debt are estimated using discounted cash flow analysis, based on market rates currently offered on such debt with similar credit risk characteristics, terms and remaining maturity. Accrued Interest Receivable and Accrued Interest Payable (Carried at Cost): The carrying amounts of accrued interest receivable and payable approximate its fair value. Off-Balance Sheet Instruments (Disclosed at Cost): Fair values for our off-balance sheet financial instruments (lending commitments and letters of credit) are based on fees currently charged in the market to enter into similar agreements, taking into account, the remaining terms of the agreements and the counterparties’ credit standing. The fair values of our financial instruments at March 31, 2018 and December 31, 2017 , were as follows:  March 31, 2018 Quoted Prices in Active Markets for Identical Assets (Level I) Significant Other Observable Inputs (Level II) Significant Unobservable Inputs (Level III) (Dollars in thousands) Carrying Amount Fair Value Financial assets: Cash and cash equivalents $ 15,080 $ 15,080 $ 15,080 $ — $ — Time deposits with other banks 200 200 — 200 — Securities available for sale 174,101 174,101 — 174,101 — Securities held to maturity 5,534 5,629 — 5,629 — Federal Home Loan Bank stock 8,358 8,358 — 8,358 — Loans receivable, net of allowance 1,080,601 1,039,947 — — 1,039,947 Accrued interest receivable 5,085 5,085 — 5,085 — Interest rate swaps 2,558 2,558 — 2,558 —  Financial liabilities: Non-maturity deposits 781,565 781,565 — 781,565 — Time deposits 261,766 239,533 — 239,533 — Short-term borrowings 125,025 125,033 125,033 — — Long-term borrowings 30,000 28,935 — 28,935 — Subordinated debentures 27,851 25,399 — 25,399 — Accrued interest payable 533 533 — 533 —  December 31, 2017 Quoted Prices in Active Markets for Identical Assets (Level I) Significant Other Observable Inputs (Level II) Significant Unobservable Inputs (Level III) (Dollars in thousands) Carrying Amount Fair Value Financial assets: Cash and cash equivalents $ 11,646 $ 11,646 $ 11,646 $ — $ — Time deposits with other banks 100 100 — 100 — Securities available for sale 98,730 98,730 — 98,730 — Securities held to maturity 5,304 5,430 — 5,430 — Federal Home Loan Bank stock 4,925 4,925 — 4,925 — Loans receivable, net of allowance 813,365 788,119 — — 788,119 Accrued interest receivable 2,472 2,472 — 2,472 — Interest rate swaps 1,451 1,451 — 1,451 —  Financial liabilities: Non-maturity deposits 563,694 563,694 — 563,694 — Time deposits 198,797 197,549 — 197,549 — Short-term borrowings 55,350 55,335 55,335 — — Long-term borrowings 35,000 34,761 — 34,761 — Subordinated debentures 27,848 25,259 — 25,259 — Accrued interest payable 470 470 — 470 —

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	DERIVATIVES The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three months ended March 31, 2018 such derivatives were used to hedge the variable cash outflows associated with four FHLB borrowings totaling $26.0 million . The Company entered into an interest rate swap agreement to hedge its $12.5 million variable rate (3 Mo Libor + 1.44% ) junior subordinated debt issued by Sussex Capital Trust II, a non-consolidated wholly-owned subsidiary of the Company, for 10 years at a fixed rate of 3.10% . The ineffective portion of the change in fair value of the derivatives are recognized directly in earnings. The Company implemented this program during the quarter ended March 31, 2016. During the three months ended March 31, 2018 and 2017, the Company did not record any hedge ineffectiveness. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Statements of Financial Condition at March 31, 2018 and December 31, 2017:  March 31, 2018  Notional/ Contract Amount Fair Value Balance Sheet Location Expiration Date (Dollars in thousands) Derivatives designated as hedging instruments Interest rate swaps by effective date: March 15, 2016 $ 12,500 $ 935 Other Assets March 15, 2026 December 15, 2016 5,000 303 Other Assets December 15, 2026 June 15, 2017 6,000 349 Other Assets June 15, 2027 December 15, 2017 10,000 659 Other Assets December 15, 2027 December 15, 2017 5,000 312 Other Assets December 15, 2027  Total $ 38,500 $ 2,558 December 31, 2017 Notional/ Contract Amount Fair Value Balance Sheet Location Expiration Date (Dollars in thousands) Derivatives designated as hedging instruments Interest rate swaps by effective date: March 15, 2016 $ 12,500 $ 610 Other Assets March 15, 2026 December 15, 2016 5,000 161 Other Assets December 15, 2026 June 15, 2017 6,000 170 Other Assets June 15, 2027 December 15, 2017 10,000 352 Other Assets December 15, 2027 December 15, 2017 5,000 158 Other Assets December 15, 2027  Total $ 38,500 $ 1,451 The table below presents the Company’s derivative financial instruments that are designated as cash flow hedgers of interest rate risk and their effect on the Company’s Consolidated Statements of Financial Conditions during the three months ended March 31, 2018 and 2017: ໿  Three Months Ended March 31, 2018  Amount of Gain Recognized in OCI on Derivatives, net of Tax (Effective Portion) Location of Gain (Loss) Recognized in Income of Derivatives (Ineffective Portion) Amount of Gain (Loss) Recognized in Income of Derivatives (Ineffective Portion) (Dollars in thousands) Derivatives in cash flow hedges Interest rate swaps by effective date: March 15, 2016 $ 234 Not applicable $ — December 15, 2016 103 Not applicable — June 15, 2017 129 Not applicable — December 15, 2017 220 Not applicable — December 15, 2017 111 Not applicable —  Total $ 797 $ — Three Months Ended March 31, 2017 Amount of Gain Recognized in OCI on Derivatives, net of Tax (Effective Portion) Location of Gain (Loss) Recognized in Income of Derivatives (Ineffective Portion) Amount of Gain (Loss) Recognized in Income of Derivatives (Ineffective Portion) (Dollars in thousands) Derivatives in cash flow hedges Interest rate swaps by effective date: March 15, 2016 $ 13 Not applicable $ — December 15, 2016 8 Not applicable — June 15, 2017 1 Not applicable — December 15, 2017 1 Not applicable — December 15, 2017 1 Not applicable —  Total $ 24 $ — The Company has master netting arrangements with its counterparty.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements include the accounts of SB One Bancorp, formerly Sussex Bancorp, (“we,” “us,” “our” or the “company”) and our wholly owned subsidiary SB One Bank, formerly Sussex Bank (the “Bank”). The corporate name change was voted and approved during the shareholder meeting on April 25, 2018. The name changes were a part of a larger rebrand effort undertaken by Sussex Bank which merged with Community Bank of Bergen County, NJ earlier this year. The Bank’s wholly owned subsidiaries are SCB Investment Company, Inc., SCBNY Company, Inc., ClassicLake Enterprises, LLC, PPD Holding Company, LLC, Community Investing Company, Inc., and SB One Insurance Agency Inc. ("SB One Insurance Agency"), formerly Tri-State Insurance Agency, Inc., a full service insurance agency located in Sussex County, New Jersey with a satellite office located in Bergen County, New Jersey. SB One Insurance Agency’s operations are considered a separate segment for financial disclosure purposes. All inter-company transactions and balances have been eliminated in consolidation. The Bank operates fourteen banking offices: eight located in Sussex County, New Jersey, four located in Bergen County, New Jersey, one located in Warren County, New Jersey, and one in Queens County, New York. We are subject to the supervision and regulation of the Board of Governors of the Federal Reserve System (the “FRB”). The Bank’s deposits are insured by the Deposit Insurance Fund (“DIF”) of the FDIC up to applicable limits. The operations of the company and the Bank are subject to the supervision and regulation of the FRB, the FDIC and the New Jersey Department of Banking and Insurance (the “Department”) and the operations of SB One Insurance Agency are subject to supervision and regulation by the Department. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information. Accordingly, they do not include all of the information and footnotes required by the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for full year financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal, recurring nature. Operating results for the three month periods ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto that are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 .
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued an Accounting Standard Update (“ASU”) 2014-09 to amend its guidance on “Revenue from Contracts with Customers, (Topic 606). The objective of the ASU is to align the recognition of revenue with the transfer of promised goods or services provided to customers in an amount that reflects the consideration which the entity expects to be entitled in exchange for those goods or services. This ASU will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective. In August 2015, the FASB issued an amendment (ASU 2015-14) which defers the effective date of this new guidance by one year. More detailed implementation guidance on Topic 606 was issued in March 2016 (ASU 2016-08), April 2016 (ASU 2016-10), May 2016 (ASU 2016-12), December 2016 (ASU 2016-20), February 2017 (ASU 2017-05) and September 2017 (ASU 2017-13), and the effective date and transition requirements for these ASUs are the same as the effective date and transition requirements of ASU 2014-09. The amendments in Topic 606 are effective for public business entities for annual periods beginning after December 15, 2017. Approximately 82% of the Company’s revenue for the quarter ended March 31, 2018, was comprised of interest income on financial assets, which are explicitly excluded from the scope of Topic 606. With respect to our non-interest income, management has identified revenue streams within the scope of the guidance, primarily service fees on deposits, ATM and debit card fees and insurance commissions and fees which are discussed below. Topic 606 states that revenue should be recognized when the entity satisfies a performance obligation by transferring goods or services to the customer. An asset is considered transferred when the customer obtains control of the asset and is able to use and obtain substantially all of the benefits of the asset. The entity then has to determine whether the performance obligation was satisfied over time or at a point in time to determine when to recognize revenue. The Company determined based on the criteria presented in Topic 606 that the performance obligations were satisfied at a point in time since the customer obtains immediate control of the deposit accounts, ATM/Debit Card and insurance policy and there are no additional obligations that the Company performs over time; therefore, the revenue would be recognized as received. The Company recognized $328 thousand in income for Service fees on deposit accounts and $1.9 million in insurance commissions and fees for the three months ended March 31, 2018. The Company currently presents the revenue and associated costs on a gross basis. ASU 2014-09 and related amendments were adopted effective January 1, 2018, using the cumulative effect approach. Under this alternative, the Company applied the new revenue standard only to contracts that were incomplete under legacy U.S. GAAP at the date of initial application and evaluated the cumulative effect of the new standard as a potential adjustment to the opening balance of retained earnings. The Company`s adoption of the ASU on January 1, 2018 did not significantly change the recognition of revenue on the Company's consolidated financial statements and, as such, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Service fees on deposit accounts represent account analysis fees, monthly service fees, check ordering fees and other deposit related fees. Revenue is recognized when the performance obligation is completed, which is generally monthly for account maintenance services or when a transaction has been completed. Insurance commissions and fees represent insurance policies that our insurance agency, SB One Insurance Agency, arranges between the policy holder and the related insurance agency. SB One Insurance Agency acts solely as an insurance broker that provides the service of connection between a policy holder and carrier. SB One Insurance Agency’s performance obligation is satisfied once the policy becomes active therefore no other performance obligation is required. Revenues for the commissions to SB One Insurance Agency’s insurance contracts will generally be recognized as of the effective date of the insurance policy or the date on which the policy premium is processed into our systems, whichever is later. Commission revenues related to installment billings are recognized on the latter of effective or invoiced date. Subsequent commission adjustments are recognized upon our receipt of notification from insurance companies concerning matters necessitating such adjustments. Profit-sharing contingent commissions are recognized when determinable, which is generally when such commissions are received from insurance companies, or when we receive formal notification of the amount of such payments. The Company recognized $213 thousand in ATM and debit card fees. ATM and debit card fees are primarily comprised of debit and credit card income (interchange fees), 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 our card payment network. The Company currently presents the revenue and associated costs with debit and credit card income on a net basis. 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, agency fee income, and other services. The Company’s performance obligation for fees 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 within one month. Under Topic 606, 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. In connection with the adoption of Topic 606, an entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. Upon adoption of Topic 606, the Company did not capitalize any contract acquisition cost. In January 2016, FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01, 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. In addition, the amendments in this ASU require an entity to disclose the fair value of its financial instruments using the exit price notion. Exit price is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. For public entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company has updated the fair value disclosure on Note 12 Fair Value of Financial Instruments in this report to reflect adoption of this standard, to include using the exit price notion in the fair value disclosure of financial instruments. The Company`s adoption of the ASU did not have a significant impact on the Company's consolidated financial statements. In February 2016, FASB issued ASU 2016-02, Leases (Topic 842). Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted for all public business entities 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 Company currently expects that upon adoption of ASU 2016-02, right-of-use assets and lease liabilities will be recognized in the consolidated balance sheet in amounts that will be material; however, there will be no material impact on operations. In June, 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326) (the “ASU”), which introduces new guidance for the accounting for credit losses on instruments within its scope. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale (AFS) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The ASU will be effective for public business entities that are SEC filers in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All other entities will have one additional year. Early application of the guidance will be permitted for all entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. The Company has taken steps to prepare for implementation when it becomes effective, such as evaluating the potential use of outside professionals for an updated model. In August 2016, FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force), which addresses eight classification issues related to the statement of cash flows: (i) debt prepayment or debt extinguishment costs, (ii) settlement of zero-coupon bonds, (iii) contingent consideration payments made after a business combination, (iv) proceeds from the settlement of insurance claims, (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (vi) distributions received from equity method investees, (vii) beneficial interests in securitization transactions, and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the ASU in an interim period, 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. Entities should apply this ASU using a retrospective transition method to each period presented. If it is impracticable for an entity to apply the ASU retrospectively for some of the issues, it may apply the amendments for those issues prospectively as of the earliest date practicable. The Company`s adoption of the ASU did not have a significant impact on the Company's consolidated financial statements. In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). The main objective of this ASU is to simplify the accounting for goodwill impairment by requiring impairment charges be based upon the first step in the current two-step impairment test under Accounting Standards Codification (ASC) 350. Currently, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). This ASU’s objective is to simplify how all entities assess goodwill for impairment by eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the impact of the pending adoption on its consolidated financial statements. In March 2017, FASB issued ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities (Subtopic 310-20). The update shortens the amortization period for premiums on purchased callable debt securities to the earliest call date. The amendment will apply only to callable debt securities with explicit, noncontingent call features that are callable at fixed prices and on preset dates, apply to all premiums on callable debt securities, regardless of how they were generated, and require companies to reset the effective yield using the payment terms of the debt security if the call option is not exercised on the earliest call date. The ASU does not require an accounting change for securities held at a discount. The discount continues to be amortized to maturity and does not apply when the investor has already incorporated prepayments into the calculation of its effective yield under other GAAP. The amendments in the ASU are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted, including adoption in an interim 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. The Company's adoption of the ASU will not have a significant impact on the Company's consolidated financial statements. In August 2017, FASB issued ASU 2017-12 Derivatives and Hedging (Topic 815). The objective of the ASU is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements and to make improvements to simplify the application of hedge accounting guidance in current GAAP. The amendments in the ASU will, among other things, 1) permit hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risks; 2) change the guidance for designating fair value hedges of interest rate risk and for measuring the change in fair value of the hedged item in fair value hedges of interest rate risk; 3) modify disclosures to include a tabular disclosure related to the effect on the income statement of fair value and cash flow hedges; and 4) eliminate the requirement to disclose the ineffective portion of the change in fair value of hedging instruments. These changes will more closely align the results of cash flow and fair value hedge accounting with risk management activities and the presentation of hedge results in the financial statements. ASU 2017-12 will be effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For all other entities, the ASU will be effective for fiscal years beginning after December 15, 2019 and interim periods within fiscal years beginning after December 15, 2020. Early application is permitted in any interim period after issuance of the update with all transition requirements and elections being applied to hedging relationships existing on the date of adoption. The Company's adoption of the ASU will not have a significant impact on the Company's consolidated financial statements.
