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 Sussex Bancorp (“we,” “us,” “our” or the “company”) and our wholly owned subsidiary Sussex Bank (the “Bank”). The Bank’s wholly owned subsidiaries are SCB Investment Company, Inc., SCBNY Company, Inc., ClassicLake Enterprises, LLC, Wheatsworth Properties Corp., PPD Holding Company, LLC, and Tri-State Insurance Agency, Inc. (“Tri-State”), a full service insurance agency located in Sussex County, New Jersey with a satellite office located in Bergen County, New Jersey. Tri-State’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 eleven banking offices, eight located in Sussex County, New Jersey, one 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 Tri-State 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 and nine month periods ended September 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. 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, 2015. New Accounting Standards In May 2014, Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The ASU’s core principle is built on the contract between a vendor and a customer for the provision of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the standard requires five basic steps: i) identify the contract with the customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies a performance obligation. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Accordingly, the amendments are effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for annual and interim reporting periods beginning after December 15, 2016. In March, 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), that clarifies how to apply revenue recognition guidance related to whether an entity is a principal or an agent. The update clarifies that an entity is a principal when it controls the specified good or service before that good or service is transferred to the customer, and is an agent when it does not control the specified good or service before it is transferred to the customer. In May, 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients, that amended its new revenue recognition guidance on transition, collectibility, noncash consideration and the presentation of sales and other similar taxes. The amendments clarify that, for a contract to be considered completed at transition, all (or substantially all) of the revenue must have been recognized under legacy GAAP. The FASB also added a practical expedient to ease transition for contracts that were modified prior to adoption of the revenue standard under both the full and modified retrospective transition approaches. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In June 2014, FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force), to clarify that a performance target in a share-based compensation award that could be achieved after an employee completes the requisite service period should be treated as a performance condition that affects the vesting of the award. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. For all entities, the amendments are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The adoption of this guidance did not have a material impact on our consolidated financial statements. In April 2015, FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, to clarify whether a hosting arrangement (e.g., cloud computing, software as a service, infrastructure as a service, etc.) contains a software license, and thus, whether it is to be accounted for by the customer similarly to other internal-use software. Specifically, the amendments revise the scope of Subtopic 350-40 to include internal-use software accessed through a hosting arrangement only if both of the following criteria are met: (1) the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty. There is no significant penalty if the customer has the ability to take delivery of the software without incurring significant cost and the ability to use the software separately without significant loss of utility or value and (2) it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. If both of the above criteria are present in a hosting arrangement, then the arrangement contains a software license and the customer should account for that element in accordance with Subtopic 350-40 (i.e., generally capitalize and subsequently amortize the cost of the license). If both of the above criteria are not present, the customer should account for the arrangement as a service contract (i.e., expense fees as incurred). The amendments are effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. An entity can elect to adopt the amendments either (1) prospectively to all arrangements entered into or materially modified after the effective date or (2) retrospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements. 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. For public entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company is currently evaluating the impact of the pending adoption of the new standard on its 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 is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. In March 2016, FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. FASB is issuing ASU 2016-09 as part of its initiative to reduce complexity in accounting standards. The areas for simplification in this ASU 2016-09 involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual 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. An entity that elects early adoption must adopt all of the amendments in the same period. The Company is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. 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. 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. For all other entities, the ASU is effective for annual periods in fiscal years beginning after December 15, 2018, and interim periods in fiscal years beginning after December 15, 2019. 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 is currently evaluating the pending adoption of the new standard on its consolidated financial statements.
