Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Principles of consolidation The accompanying consolidated financial statements include the accounts of GSE Systems, Inc. and its wholly-owned subsidiaries (collectively, "the Company"). All intercompany balances and transactions have been eliminated in consolidation. Investments in partnerships, joint ventures, and less-than-majority owned subsidiaries in which the Company has significant influence are accounted for under the equity method. Accounting estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company evaluates the estimates used, including but not limited to those related to revenue recognition, the allowance for doubtful accounts, estimates of future warranty costs, impairments of goodwill and other intangible assets and contingent consideration to be paid in business acquisitions, valuation of stock based compensation awards, and income taxes. Actual results could differ from these estimates. Revenue recognition The Company recognizes revenue through fixed price contracts for the sale of uniquely designed/customized systems containing hardware, software and other materials which generally apply to the Performance Improvement Solutions segment and time and material contracts for Nuclear Industry Training and Consulting support and service agreements. In accordance with ASC 605-35 , Construction-Type and Production-Type Contracts ) Uncertainties inherent in the performance of contracts include labor availability and productivity, material costs, change order scope and pricing, software modification and customer acceptance issues. The reliability of these cost estimates is critical to the Company's revenue recognition as a significant change in the estimates can cause the Company's revenue and related margins to change significantly from the amounts estimated in the early stages of the project. As the Company recognizes revenue under the percentage-of-completion method, it provides an accrual for estimated future warranty costs based on historical and projected claims experience. The Company's long-term contracts generally provide for a one to five year warranty on the systems sold to customers to cover hardware or software issues. The Company's system design contracts do not normally provide for post contract support (PCS) in terms of software upgrades, software enhancements or telephone support. In order to obtain PCS, the customers must normally purchase a separate contract. Such PCS arrangements are generally for a one-year period renewable annually and include customer support, unspecified software upgrades, and maintenance releases. The Company recognizes revenue from these contracts ratably over the life of the agreements. Revenue from the sale of software licenses without other elements in the contract and which do not require significant modifications or customization for the Company's modeling tools are recognized when the license agreement is signed, the license fee is fixed and determinable, delivery has occurred, and collection is considered probable. We utilize written contracts as a means to establish the terms and conditions by which product support and services are sold to customers. Delivery is considered to have occurred when title and risk of loss have been transferred to the customer, which generally occurs after a license key has been delivered electronically to the customer. The Company also recognizes revenue from the sale of software licenses from contracts with multiple deliverables. These software license sales are evaluated under ASC 985-605, Software Revenue Recognition The Company recognizes revenue under time and materials contracts primarily from the Nuclear Industry Training and Consulting segment and certain cost-reimbursable contracts. Revenue on time and material contracts is recognized as services are rendered and performed. Under a typical time-and-materials billing arrangement, customers are billed on a regularly scheduled basis, such as biweekly or monthly. Any unbilled amounts are typically billed the following month. Under cost-reimbursable contracts, which are subject to a contract ceiling amount, we are reimbursed for allowable costs and paid a fee, which may be fixed or performance based. However, if costs exceed the contract ceiling or are not allowable under the provisions of the contract or applicable regulations, we may not be able to obtain reimbursement for all such costs. Cash and cash equivalents Cash and cash equivalents represent cash and highly liquid investments including money market accounts with maturities of three months or less at the date of purchase. Restricted cash Restricted cash consists of the cash collateralization of outstanding letters of credit used for various advance payment, bid, surety and performance bonds, and negative foreign exchange positions which have been segregated into restricted money market accounts with BB&T Bank. BB&T Bank has complete and unconditional control over the restricted money market accounts. At December 31, 2016 and 2015, the Company had approximately $1.1 million and $3.6 million, respectively, of cash in escrow accounts with BB&T Bank. We have classified all of our restricted cash as current assets at December 31, 2016, and classified as current assets $1.8 million of the total restricted cash at December 31, 2015, with the remaining amount classified as a long term asset. The Company recorded interest income of $6,000 and $10,000 from the escrow accounts for the years ended December 31, 2016 and 2015, respectively. The interest earned on these restricted funds is added to the restricted cash balance. The Company classifies the restriction and release of the cash collateralization of outstanding letters of credit as an investing activity within the consolidated statements of cash flows, as these deposits are not related to borrowings against our line of credit. Contract receivables, net Contract receivables include recoverable costs and accrued profit not billed which represents revenue recognized in excess of amounts billed. Billings in excess of costs and estimated earnings on uncompleted contracts in the accompanying consolidated balance sheets represent advanced billings to clients on contracts in advance of work performed. Generally, such amounts will be earned and recognized over the next twelve months. Billed receivables are recorded at invoiced amounts. The allowance for doubtful accounts is based on historical trends of past due accounts, write-offs, and specific identification and review of customer accounts. The activity in the allowance for doubtful accounts is as follows: (in thousands) As of and for the years ended December 31, 2016 2015 Beginning balance $ 103 $ 22 Current year provision - 101 Current year write-offs (86 ) (20 ) Ending balance $ 17 $ 103 Equipment, software and leasehold improvements, net Equipment and purchased software are recorded at cost and depreciated using the straight-line method with estimated useful lives ranging from three to ten years. Leasehold improvements are amortized over the life of the lease or the estimated useful life, whichever is shorter, using the straight-line method. Upon sale or retirement, the cost and related depreciation are eliminated from the respective accounts and any resulting gain or loss is included in operations. Maintenance and repairs are charged to expense as incurred. Software development costs Certain computer software development costs are capitalized in the accompanying consolidated balance sheets. Capitalization of computer software development costs begins upon the establishment of technological feasibility. Capitalization ceases and amortization of capitalized costs begins when the software product is commercially available for general release to customers. Amortization of capitalized computer software development costs is included in cost of revenue and is determined using the straight-line method over the remaining estimated economic life of the product, typically three years. On an annual basis, and more frequently as conditions indicate, the Company assesses the recovery of the unamortized software development costs by estimating the net undiscounted cash flows expected to be generated by the sale of the product. If the undiscounted cash flows are not sufficient to recover the unamortized software costs the Company will write-down the carrying amount of such asset to its estimated fair value based on the future discounted cash flows. The excess of any unamortized computer software costs over the related fair value is written down and charged to operations. Development expenditures Development expenditures incurred to meet customer specifications under contracts are charged to contract costs. Company sponsored development expenditures are either charged to operations as incurred and are included in selling, general and administrative expenses or are capitalized as software development costs. See Note 7, Software development costs, net Impairment of long-lived assets Long-lived assets, such as equipment, purchased software, capitalized software development costs, and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized at the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. During the third quarter of 2015, the Company's new CEO conducted a review of the Company's organizational cost structure and software development plans. Based upon this review, the Company made the decision to terminate its Enterprise Data Management (EDM) software development program and recorded a $1.5 million write-down representing the capitalized balance of its EDM software development projects in the third quarter 2015. No impairment was recorded during 2016. Goodwill and intangible assets The Company's intangible assets include amounts recognized in connection with business acquisitions, including customer relationships, contract backlog and software. Intangible assets are initially valued at fair value using generally accepted valuation methods appropriate for the type of intangible asset. Amortization is recognized on a straight-line basis over the estimated useful life of the intangible assets, except for contract backlog and contractual customer relationships which are recognized in proportion to the related projected revenue streams. Intangible assets with definite lives are reviewed for impairment if indicators of impairment arise. The Company does not have any intangible assets with indefinite useful lives. Goodwill represents the excess of costs over fair value of assets of businesses acquired. The Company reviews goodwill for impairment annually as of December 31 and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable in accordance with Accounting Standard Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment, Intangibles — Goodwill and Other ASU 2011-08 permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Under ASU 2011-08, an entity is not required to perform step one of the goodwill impairment test for a reporting unit if it is more likely than not that its fair value is greater than its carrying amount. For the annual goodwill impairment test as of December 31, 2016, the Company performed a quantitative step one goodwill impairment test and concluded that the fair values of each of the reporting units exceeded their respective carrying values. Foreign currency translation Balance sheet accounts for foreign operations are translated at the exchange rate as of the balance sheet date, and income statement accounts are translated at the average exchange rate for the year. The resulting translation adjustments are included in accumulated other comprehensive loss. Transaction gains and losses resulting from changes in exchange rates are recorded in our statements of operations in the year in which they occur. For the years ended December 31, 2016, and 2015, foreign currency transaction losses were approximately $69,000 and $34,000, respectively. Accrued warranty For contracts that contain a warranty provision, the Company provides an accrual for estimated future warranty costs based on historical experience and projected claims. The Company's contracts may contain warranty provisions from one to five years. The current portion of the accrued warranty is presented separately on the Consolidated Balance Sheets within Current liabilities whereas the noncurrent portion is included in Other liabilities. The activity in the accrued warranty accounts is as follows: (in thousands) As of and for the years ended December 31, 2016 2015 Beginning balance $ 1,614 $ 1,456 Current year provision 355 626 Current year claims (467 ) (455 ) Currency adjustment (24 ) (13 ) Ending balance $ 1,478 $ 1,614 Income taxes Income taxes are provided under the asset and liability method. Under this method, deferred income taxes are determined based on the differences between the consolidated financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amounts expected to be realized. A provision is made for the Company's current liability for federal, state and foreign income taxes and the change in the Company's deferred income tax assets and liabilities. We establish accruals for uncertain tax positions taken or expected to be taken in a tax return when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities that have full knowledge of all relevant information. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Favorable or unfavorable adjustment of the accrual for any particular issue would be recognized as an increase or decrease to income tax expense in the period of a change in facts and circumstances. Interest and penalties related to income taxes are accounted for as income tax expense. Stock-based compensation Compensation expense related to share based awards is recognized on a pro rata straight-line basis based on the value of share awards that are scheduled to vest during the requisite service period. During the years ended December 31, 2016 and 2015, the Company recognized $1.6 million and $0.5 million, respectively, of pre-tax stock-based compensation expense under the fair value method. During 2016, the Company recognized approximately $151,000 of compensation expense related to cash-settled RSUs. Earnings (loss) per share Basic earnings (loss) per share is based on the weighted average number of outstanding common shares for the period. Diluted earnings (loss) per share adjusts the weighted average shares outstanding for the potential dilution that could occur if outstanding vested stock options were exercised. Basic and diluted earnings (loss) per share is based on the weighted average number of outstanding shares for the period. The number of common shares and common share equivalents used in the determination of basic and diluted loss per share were as follows: (in thousands, except for per share data) Years ended December 31, 2016 2015 Numerator: Net income (loss) $ 1,422 $ (4,705 ) Denominator: Weighted-average shares outstanding for basic income (loss) per share 18,218,681 17,892,891 Effect of dilutive securities: Stock options and restricted stock units 293,585 - Adjusted weighted-average shares outstanding and assumed conversions for diluted income (loss) per share 18,512,266 17,892,891 Shares related to dilutive securities excluded because inclusion would be anti-dilutive 677,964 2,492,710 Conversion of certain outstanding stock options was not assumed for the years ended December 31, 2016 and 2015 because the impact would have been anti-dilutive. Significant customers and concentration of credit risk We have a concentration of revenue from an individual customer, which accounted for approximately 10.2% and 15.9% of our consolidated revenue for the years ended December 31, 2016 and 2015, respectively. No other individual customer accounted for more than 10% of our consolidated revenue in 2016 or 2015. Fair values of financial instruments The carrying amounts of current assets and current liabilities reported in the consolidated balance sheets approximate fair value due to their short term duration. Contingent consideration for business acquisitions Acquisitions may include contingent consideration payments based on future financial measures of an acquired company. Contingent consideration is required to be recognized at fair value as of the acquisition date. The Company estimates the fair value of these liabilities based on financial projections of the acquired companies and estimated probabilities of achievement. At each reporting date, the contingent consideration obligation is revalued to estimated fair value and changes in fair value subsequent to the acquisition are reflected in income or expense in the consolidated statements of operations, and could cause a material impact to our operating results. Changes in the fair value of contingent consideration obligations may result from changes in discount periods and rates, changes in the timing and amount of revenue and/or earnings estimates and changes in probability assumptions with respect to the likelihood of achieving the various earn-out criteria. Derivative instruments The Company utilizes forward foreign currency exchange contracts to manage market risks associated with the fluctuations in foreign currency exchange rates. It is the Company's policy to use such derivative financial instruments to protect against market risk arising in the normal course of business in order to reduce the impact of these exposures. The Company minimizes credit exposure by limiting counterparties to nationally recognized financial institutions. As of December 31, 2016, the Company had foreign exchange contracts outstanding of approximately 281.4 million Japanese Yen, 0.6 million Australian Dollars, 0.5 million Canadian Dollars, and 0.1 million Euro. At December 31, 2015, the Company had foreign exchange contracts outstanding of approximately 2.1 million Euro, 1.3 million Canadian Dollars, 0.5 million Pounds Sterling and 0.4 million Australian Dollars at fixed rates. The contracts expire on various dates through December 2018. The Company had not designated the foreign exchange contracts as hedges and had recorded the estimated fair value of the contracts in the consolidated balance sheet as follows: December 31, (in thousands) 2016 2015 Asset derivatives Prepaid expenses and other current assets $ 57 $ 115 Other assets 84 6 141 121 Liability derivatives Other current liabilities (20 ) (57 ) (20 ) (57 ) Net fair value $ 121 $ 64 The changes in the fair value of the foreign exchange contracts are included in gain (loss) on derivative instruments, net in the consolidated statements of operations. The foreign currency denominated trade receivables, unbilled receivables, billings in excess of revenue earned and subcontractor accruals that are related to the outstanding foreign exchange contracts are remeasured at the end of each period into the functional currency using the current exchange rate at the end of the period. The gain or loss resulting from such remeasurement is also included in gain (loss) on derivative instruments net in the consolidated statements of operations. For the years ended December 31, 2016 and 2015, the Company recognized a loss on its derivative instruments net as outlined below: Years ended December 31, (in thousands) 2016 2015 Foreign exchange contracts- change in fair value $ 51 $ (6 ) Remeasurement of related contract receivables and billings in excess of revenue earned (69 ) (34 ) $ (18 ) $ (40 ) Reclassifications Certain prior year amounts have been reclassified to conform with the current year presentation. Subcontractor payables have been reclassified on the Consolidated Balance Sheets from Accounts payable to Accrued expenses. In addition, the Company reclassified research and development costs from Selling, general and administrative expenses and presented them as a separate caption within Operating expenses on the Consolidated Statement of Operations. The Company also reclassified the current portion of deferred taxes to noncurrent within Other assets and Other liabilities on the Consolidated Balance Sheets. Accounting pronouncements recently adopted In November 2015, the Financial Accounting Standards Board (FASB) issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Accounting pronouncements not yet adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers In July 2015, FASB issued ASU 2015-11, Simplifying the Measurement of Inventory . ASU 2015-11 requires that an entity measure inventory at the lower of cost and net realizable value. This ASU does not apply to inventory measured using last-in, first-out. ASU 2015-11 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. We do not expect the new standard to have a significant impact on our consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Topic 718: Improvements to Employee Share Based Accounting In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the definition of a Business , which amends the current definition of a business. Under ASU 2017-01, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contributes to the ability to create outputs. ASU 2017-01 further states that when substantially all of the fair value of gross assets acquitted is concentrated in a single asset (or a group of similar assets), the assets acquired would not represent a business. The new guidance also narrows the definition of the term "outputs" to be consistent with how it is described in Topic 606, Revenue from Contracts with Customers . The changes to the definition of a business will likely result in more acquisitions being accounted for as asset acquisitions. ASU 2017-01 is effective for acquisitions commencing on or after June 30, 2019, with early adoption permitted. Adoption of this guidance will be applied prospectively on or after the effective date. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other . ASU 2017-04 simplifies the accounting for goodwill impairment by eliminating Step 2 of the current goodwill impairment test, which required a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which the reporting unit's carrying value exceeds its fair value, limited to the carrying value of the goodwill. ASU 2017-04 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2019.

Goodwill and Intangible Assets [Abstract]
Goodwill and Intangible Assets	2. Goodwill and Intangible Assets Goodwill The Company reviews goodwill for impairment annually as of December 31 and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company tests goodwill at the reporting unit level. A reporting unit is an operating segment, or one level below an operating segment, as defined by U.S. GAAP. After the acquisition of Hyperspring on November 14, 2014, the Company determined that it had two reporting units, which are the same as our two operating segments: (i) Performance Improvement Solutions; and (ii) Nuclear Industry Training and Consulting (which includes Hyperspring). As of December 31, 2016 and 2015, goodwill of $5.6 million related to the Nuclear Industry Training and Consulting segment. No impairment of goodwill was recorded in 2016 or 2015.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	8. Fair Value of Financial Instruments ASC 820, Fair Value Measurement The levels of the fair value hierarchy established by ASC 820 are: Level 1: inputs are quoted prices, unadjusted, in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2: inputs are other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. A Level 2 input must be observable for substantially the full term of the asset or liability. Level 3: inputs are unobservable and reflect the reporting entity's own assumptions about the assumptions that market participants would use in pricing the asset or liability. The Company considers the recorded value of certain of its financial assets and liabilities, which consist primarily of cash equivalents, accounts receivable and accounts payable, to approximate the fair value of the respective assets and liabilities at December 31, 2016 and 2015 based upon the short-term nature of the assets and liabilities. The Company had $15.3 million and $5.4 million deposited in unrestricted money market accounts on December 31, 2016 and 2015, respectively. As of December 31, 2016, the Company was contingently liable for four standby letters of credit and one surety bond totaling $1.0 million which represent advance payment and performance bonds on four contracts. The Company has deposited the full value of the standby letters of credit into money market escrow accounts, which have been restricted in that the Company may not access these funds until the related letters of credit have expired. The cash has been recorded on the Company's consolidated balance sheet as restricted cash and long-term restricted cash depending on the expiration date of the underlying letters of credit. The following table presents assets and liabilities measured at fair value at December 31, 2016: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) (Level 1) (Level 2) (Level 3) Total Money market funds $ 16,435 $ - $ - $ 16,435 Foreign exchange contracts - 141 - 141 Total assets $ 16,435 $ 141 $ - $ 16,576 Foreign exchange contracts $ - $ (20 ) $ - $ (20 ) Contingent consideration liability - - (2,105 ) (2,105 ) Total liabilities $ - $ (20 ) $ (2,105 ) $ (2,125 ) The following table presents assets and liabilities measured at fair value at December 31, 2015: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) (Level 1) (Level 2) (Level 3) Total Money market funds $ 8,979 $ - $ - $ 8,979 Foreign exchange contracts - 121 - 121 Total assets $ 8,979 $ 121 $ - $ 9,100 Foreign exchange contracts $ - $ (57 ) $ - $ (57 ) Contingent consideration liability - - (3,732 ) (3,732 ) Total liabilities $ - $ (57 ) $ (3,732 ) $ (3,789 ) For the years ended December 31, 2016 and 2015, the Company did not have any transfers between fair value Level 1 and Level 2. The Company did not hold any non-financial assets or non-financial liabilities subject to fair value measurements on a recurring basis at December 31, 2016 or 2015. During the years ended December 31, 2016 and 2015, the Company did not have any transfers into or out of the Level 3 contingent consideration liability. The decrease in the liability during 2016 and 2015 was due to accretion of the liability and fair value adjustments, which were all recorded to income.

Long-Term Debt [Abstract]
Long-Term Debt	9. Long-Term Debt At December 31, 2016 and 2015, the Company had no long-term debt. Line of Credit BB&T Bank We previously had a Master Loan and Security Agreement and Revolving Credit Note with BB&T that provided a $7.5 million revolving line of credit for the purpose of issuing stand-by letters of credit and providing working capital. Working capital advances accrued interest at a rate equal to the Wall Street Journal Prime Rate of Interest, floating with a floor of 4.5%. As collateral for any borrowings, the Company granted a first lien and security interest in all of the assets of the Company, including but not limited to, accounts receivable, proceeds and products, intangibles, trademarks, patents, intellectual property, machinery and equipment. The agreement also required certain cash collateral and compliance with certain restrictive covenants. In connection with the Citizen's Bank credit facility noted below, this agreement was modified in December 2016 to terminate the revolving line of credit, but maintain the outstanding letters of credit through February 17, 2017. At December 31, 2016 and 2015, the cash collateral account totaled $1.1 million and $3.6 million, respectively, and was classified as restricted cash on the consolidated balance sheets. As of December 31, 2016, the Company was in compliance with its financial covenants. Citizen's Bank In December 2016, the Company entered into a new three-year, $5.0 million revolving line of credit facility with Citizen's Bank to fund general working capital needs, including acquisitions. The available credit facility is reduced for any issued and outstanding letters of credit and working capital advances. Working capital advances bear interest of LIBOR plus 2.25% per annum and letter of credit fees are 1.25% per annum. The Company is not required to maintain a restricted cash collateral account at Citizen's Bank for outstanding letters of credit and working capital advances. The credit facility agreement is subject to standard financial covenants and reporting requirements.

Income Taxes The consolidated income (loss) before income taxes, by domestic and foreign sources, is as follows: (in thousands) Years ended December 31, 2016 2015 Domestic $ 2,873 $ (4,260 ) Foreign (1,101 ) 26 Total $ 1,772 $ (4,234 ) The provision for income taxes is as follows: (in thousands) Years ended December 31, 2016 2015 Current: Federal $ - $ - State 6 12 Foreign 221 288 Subtotal 227 300 Deferred: Federal 127 127 State 19 19 Foreign (23 ) 25 Subtotal 123 171 Total $ 350 $ 471 The Company is entitled to a deduction for federal and state tax purposes with respect to employees' stock option activity. As of December 31, 2016, the Company had $5.6 million of unrecognized excess tax deductions related to compensation for stock option exercises which will be recognized when the net operating loss carryforwards are fully utilized and those excess tax benefits result in a reduction to income taxes payable. The effective income tax rate for the years ended December 31, 2016 and 2015 differed from the statutory federal income tax rate as presented below: Effective Tax Rate Percentage (%) Years ended December 31, 2016 2015 Statutory federal income tax rate 34.0% 34.0% State income taxes, net of federal tax benefit 1.3% (0.2)% Effect of foreign operations 8.6% (3.0)% Change in valuation allowance (46.9)% (33.8)% Meals and entertainment 7.7% (3.3)% Permanent differences 4.5% (3.6)% Uncertain tax positions 11.8% (4.0)% Other (1.2)% 2.8% Effective tax rate 19.8% (11.1)% Deferred income taxes arise from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. A summary of the tax effect of the significant components of the deferred income tax liabilities is as follows: (in thousands) As of December 31, 2016 2015 Deferred tax assets: Net operating loss carryforwards $ 7,868 $ 8,732 Capital loss carryforwards 549 549 Accruals 183 662 Reserves 514 719 Alternative minimum tax credit carryforwards 203 166 Stock-based compensation expense 1,224 1,492 Intangibles 391 397 Undistributed earnings of foreign subsidiary 37 - Other 71 32 Total deferred tax asset 11,040 12,749 Valuation allowance (10,477 ) (12,082 ) Total deferred tax asset less valuation allowance 563 667 Deferred tax liabilities: Undistributed earnings of foreign subsidiary - (17 ) Software development costs (382 ) (446 ) Fixed Assets (161 ) (213 ) Indefinite-lived intangibles (316 ) (170 ) Other (27 ) (22 ) Total deferred tax liability (886 ) (868 ) Net deferred tax liability $ (323 ) $ (201 ) In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future income in making this assessment. Management believes that the Company will achieve profitable operations in future years that will enable the Company to recover the benefit of its deferred tax assets. However, other than for a portion of the deferred tax assets that are related to the Company's Indian subsidiary, the Company presently does not have sufficient objective evidence to substantiate the recovery of the deferred tax assets. Accordingly, the Company has established a full $10.5 million valuation allowance on its U.S., U.K., Swedish, and Chinese deferred tax assets at December 31, 2016. The Company has a deferred tax liability in the amount of $316,000 and $170,000 at December 31, 2016 and 2015, respectively, relating to the tax amortization of goodwill that cannot be offset by deferred tax assets because the anticipated reversal of the deferred tax liability is outside of the anticipated reversal of the deferred tax assets. As of December 31, 2016 and 2015, the Company's consolidated cash and cash equivalents totaled $21.7 million and $11.1 million, respectively, including cash and cash equivalents held at non-U.S. entities totaling $4.2 million and $4.1 million, respectively. The Company has foreign operating subsidiaries located in China, United Kingdom, Sweden and India. A deferred tax asset has been recorded with respect to the undistributed earnings in Sweden in the amount of $109,000. The Company has two foreign subsidiaries located in China and United Kingdom with accumulated deficits. The Company has one foreign subsidiary located in India that has undistributed earnings of $644,000 at December 31, 2016. If the Company were to repatriate these earnings it would incur taxes of approximately $331,000. The foreign subsidiaries in China, United Kingdom, and India have undistributed earnings that are considered indefinitely reinvested as of December 31, 2016, to fund the Company's ongoing international operations. At December 31, 2016, the Company's largest deferred tax asset of $7.9 million primarily relates to a U.S. net operating loss carryforward of $18.6 million which expires in various amounts between 2020 and 2035. The amount of U.S. loss carryforward which can be used by the Company each year is limited due to changes in the Company's ownership which occurred in 2003. Thus, a portion of the Company's loss carryforward may expire unutilized. Uncertain Tax Positions Foreign Uncertain Tax Positions During 2016 and 2015, the Company recorded tax liabilities for certain foreign tax contingencies. During 2016, the Company also determined that South Korea should be included in this inventory. The Company recorded these uncertain tax positions in other current liabilities on the consolidated balance sheets. The following table outlines the Company's foreign uncertain tax liabilities, including accrued interest and penalties for each jurisdiction: China Ukraine South Korea (in thousands) Tax Interest and Penalties Tax Interest and Penalties Tax Interest and Penalties Total Balance, January 1, 2015 $ 222,000 $ - $ 61,000 $ - $ - $ - $ 283,000 Increases 3,000 152,000 - 15,000 - - 170,000 Decreases - - (40,000 ) - - - (40,000 ) Balance, December 31, 2015 $ 225,000 $ 152,000 $ 21,000 $ 15,000 $ - $ - $ 413,000 Increases - 57,000 68,000 13,000 129,000 8,000 275,000 Decreases (23,000 ) - - - - - (23,000 ) Balance, December 31, 2016 $ 202,000 $ 209,000 $ 89,000 $ 28,000 $ 129,000 $ 8,000 $ 665,000

Capital Stock	11. Capital Stock The Company's Board of Directors has authorized 32,000,000 total shares of capital stock, of which 30,000,000 are designated as common stock and 2,000,000 are designated as preferred stock. The Board of Directors has the authority to establish one or more classes of preferred stock and to determine, within any class of preferred stock, the preferences, rights and other terms of such class. As of December 31, 2016, the Company has reserved 4,892,641 shares of common stock for issuance, 1,556,833 are reserved for shares upon exercise of outstanding stock options, and 1,688,480 are reserved for shares upon vesting of restricted stock units. The Company has 1,647,328 shares available for future grants under the Company's 1995 Long-Term Incentive Plan. Preferred Stock Rights On March 21, 2011, the Board of Directors of the Company declared a dividend, payable to holders of record as of the close of business on April 1, 2011, of one preferred stock purchase right (a Right) for each outstanding share of common stock, par value $0.01 per share, of the Company (the Common Stock) and in addition, entered into a Stockholder Protection Rights Agreement (as amended from time to time, the Rights Agreement) with Continental Stock Transfer & Trust Company, as Rights Agent. The Rights traded with and were inseparable from the Common Stock and were not evidenced by separate certificates. Each Right entitled its holder to purchase from the Company one-hundredth of a share of participating preferred stock having economic and voting terms similar to the Common Stock at an exercise price of $8.00 per Right, subject to adjustment in accordance with the terms of the Rights Agreement, if the Rights had become exercisable. Under the Rights Agreement, the Rights would have become exercisable if any person or group acquired 20% or more of the Common Stock or, in the case of any person or group that owned 20% or more of the Common Stock. Upon exercise of the Right in accordance with the Rights Agreement, the holder was able to purchase a number of shares of Common Stock from the Company having an aggregate market price (as defined in the Rights Agreement) equal to twice the then-current exercise price for an amount in cash equal to the then-current exercise price. In addition, the Company, in certain circumstances and pursuant to the terms of the Rights Agreement, would have exchanged the Rights for one share of Common Stock or an equivalent security for each Right or, alternatively, redeemed the Rights for $0.001 per Right. On March 21, 2014, the Rights Agreement was amended to extend the term an additional two years. At the close of business on March 21, 2016, the Rights and the Rights Agreement expired and no person retained any rights pursuant to the Rights Agreement or any Right.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	12. Stock-Based Compensation Long-term incentive plan During 1995, the Company established the 1995 Long-Term Incentive Stock Option Plan (the Plan), which permits the granting of stock options (including incentive stock options and nonqualified stock options) stock appreciation rights, restricted or unrestricted stock awards, phantom stock, performance awards or any combination of these to employees, directors or consultants. The Plan expires on June 30, 2018; the total number of shares that could be issued under the Plan is 7,500,000. As of December 31, 2016, 2,607,359 shares have been issued under the Plan, 1,556,833 stock options and 1,688,480 restricted stock units (RSUs) were outstanding under the Plan, while 1,647,328 shares remain for future grants under the Plan. The Company recognizes compensation expense on a pro rata straight-line basis over the requisite service period for stock-based compensation awards with both graded and cliff vesting terms. The Company recognizes the cumulative effect of a change in the number of awards expected to vest in compensation expense in the period of change. The Company has not capitalized any portion of its stock-based compensation. During the years ended December 31, 2016 and 2015, the Company recognized $1,550,000 and $541,000, respectively, of stock-based compensation expense under the fair value method. During the year ended December 31, 2016, there was approximately $151,000 of stock-based compensation expense related to cash-settled RSUs. Stock options Options to purchase shares of the Company's common stock under the Plan expire in either seven or ten years from the date of grant and become exercisable in three, five, or seven installments with a certain percentage of options vesting on the first anniversary of the grant date and additional options vesting on each of the subsequent anniversaries of the grant date, subject to acceleration under certain circumstances.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Summary of Significant Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation The accompanying consolidated financial statements include the accounts of GSE Systems, Inc. and its wholly-owned subsidiaries (collectively, "the Company"). All intercompany balances and transactions have been eliminated in consolidation. Investments in partnerships, joint ventures, and less-than-majority owned subsidiaries in which the Company has significant influence are accounted for under the equity method.
Accounting estimates	Accounting estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company evaluates the estimates used, including but not limited to those related to revenue recognition, the allowance for doubtful accounts, estimates of future warranty costs, impairments of goodwill and other intangible assets and contingent consideration to be paid in business acquisitions, valuation of stock based compensation awards, and income taxes. Actual results could differ from these estimates.
Revenue recognition	Revenue recognition The Company recognizes revenue through fixed price contracts for the sale of uniquely designed/customized systems containing hardware, software and other materials which generally apply to the Performance Improvement Solutions segment and time and material contracts for Nuclear Industry Training and Consulting support and service agreements. In accordance with ASC 605-35 , Construction-Type and Production-Type Contracts ) Uncertainties inherent in the performance of contracts include labor availability and productivity, material costs, change order scope and pricing, software modification and customer acceptance issues. The reliability of these cost estimates is critical to the Company's revenue recognition as a significant change in the estimates can cause the Company's revenue and related margins to change significantly from the amounts estimated in the early stages of the project. As the Company recognizes revenue under the percentage-of-completion method, it provides an accrual for estimated future warranty costs based on historical and projected claims experience. The Company's long-term contracts generally provide for a one to five year warranty on the systems sold to customers to cover hardware or software issues. The Company's system design contracts do not normally provide for post contract support (PCS) in terms of software upgrades, software enhancements or telephone support. In order to obtain PCS, the customers must normally purchase a separate contract. Such PCS arrangements are generally for a one-year period renewable annually and include customer support, unspecified software upgrades, and maintenance releases. The Company recognizes revenue from these contracts ratably over the life of the agreements. Revenue from the sale of software licenses without other elements in the contract and which do not require significant modifications or customization for the Company's modeling tools are recognized when the license agreement is signed, the license fee is fixed and determinable, delivery has occurred, and collection is considered probable. We utilize written contracts as a means to establish the terms and conditions by which product support and services are sold to customers. Delivery is considered to have occurred when title and risk of loss have been transferred to the customer, which generally occurs after a license key has been delivered electronically to the customer. The Company also recognizes revenue from the sale of software licenses from contracts with multiple deliverables. These software license sales are evaluated under ASC 985-605, Software Revenue Recognition The Company recognizes revenue under time and materials contracts primarily from the Nuclear Industry Training and Consulting segment and certain cost-reimbursable contracts. Revenue on time and material contracts is recognized as services are rendered and performed. Under a typical time-and-materials billing arrangement, customers are billed on a regularly scheduled basis, such as biweekly or monthly. Any unbilled amounts are typically billed the following month. Under cost-reimbursable contracts, which are subject to a contract ceiling amount, we are reimbursed for allowable costs and paid a fee, which may be fixed or performance based. However, if costs exceed the contract ceiling or are not allowable under the provisions of the contract or applicable regulations, we may not be able to obtain reimbursement for all such costs.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents represent cash and highly liquid investments including money market accounts with maturities of three months or less at the date of purchase.
Restricted cash	Restricted cash Restricted cash consists of the cash collateralization of outstanding letters of credit used for various advance payment, bid, surety and performance bonds, and negative foreign exchange positions which have been segregated into restricted money market accounts with BB&T Bank. BB&T Bank has complete and unconditional control over the restricted money market accounts. At December 31, 2016 and 2015, the Company had approximately $1.1 million and $3.6 million, respectively, of cash in escrow accounts with BB&T Bank. We have classified all of our restricted cash as current assets at December 31, 2016, and classified as current assets $1.8 million of the total restricted cash at December 31, 2015, with the remaining amount classified as a long term asset. The Company recorded interest income of $6,000 and $10,000 from the escrow accounts for the years ended December 31, 2016 and 2015, respectively. The interest earned on these restricted funds is added to the restricted cash balance. The Company classifies the restriction and release of the cash collateralization of outstanding letters of credit as an investing activity within the consolidated statements of cash flows, as these deposits are not related to borrowings against our line of credit.
Contract receivables	Contract receivables, net Contract receivables include recoverable costs and accrued profit not billed which represents revenue recognized in excess of amounts billed. Billings in excess of costs and estimated earnings on uncompleted contracts in the accompanying consolidated balance sheets represent advanced billings to clients on contracts in advance of work performed. Generally, such amounts will be earned and recognized over the next twelve months. Billed receivables are recorded at invoiced amounts. The allowance for doubtful accounts is based on historical trends of past due accounts, write-offs, and specific identification and review of customer accounts. The activity in the allowance for doubtful accounts is as follows: (in thousands) As of and for the years ended December 31, 2016 2015 Beginning balance $ 103 $ 22 Current year provision - 101 Current year write-offs (86 ) (20 ) Ending balance $ 17 $ 103
Equipment, software and leasehold improvements, net	Equipment, software and leasehold improvements, net Equipment and purchased software are recorded at cost and depreciated using the straight-line method with estimated useful lives ranging from three to ten years. Leasehold improvements are amortized over the life of the lease or the estimated useful life, whichever is shorter, using the straight-line method. Upon sale or retirement, the cost and related depreciation are eliminated from the respective accounts and any resulting gain or loss is included in operations. Maintenance and repairs are charged to expense as incurred.
Software development costs	Software development costs Certain computer software development costs are capitalized in the accompanying consolidated balance sheets. Capitalization of computer software development costs begins upon the establishment of technological feasibility. Capitalization ceases and amortization of capitalized costs begins when the software product is commercially available for general release to customers. Amortization of capitalized computer software development costs is included in cost of revenue and is determined using the straight-line method over the remaining estimated economic life of the product, typically three years. On an annual basis, and more frequently as conditions indicate, the Company assesses the recovery of the unamortized software development costs by estimating the net undiscounted cash flows expected to be generated by the sale of the product. If the undiscounted cash flows are not sufficient to recover the unamortized software costs the Company will write-down the carrying amount of such asset to its estimated fair value based on the future discounted cash flows. The excess of any unamortized computer software costs over the related fair value is written down and charged to operations.
Development expenditures	Development expenditures Development expenditures incurred to meet customer specifications under contracts are charged to contract costs. Company sponsored development expenditures are either charged to operations as incurred and are included in selling, general and administrative expenses or are capitalized as software development costs. See Note 7, Software development costs, net
Impairment of long-lived assets	Impairment of long-lived assets Long-lived assets, such as equipment, purchased software, capitalized software development costs, and intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized at the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of would be separately presented in the consolidated balance sheets and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. During the third quarter of 2015, the Company's new CEO conducted a review of the Company's organizational cost structure and software development plans. Based upon this review, the Company made the decision to terminate its Enterprise Data Management (EDM) software development program and recorded a $1.5 million write-down representing the capitalized balance of its EDM software development projects in the third quarter 2015. No impairment was recorded during 2016.
Goodwill and intangible assets	Goodwill and intangible assets The Company's intangible assets include amounts recognized in connection with business acquisitions, including customer relationships, contract backlog and software. Intangible assets are initially valued at fair value using generally accepted valuation methods appropriate for the type of intangible asset. Amortization is recognized on a straight-line basis over the estimated useful life of the intangible assets, except for contract backlog and contractual customer relationships which are recognized in proportion to the related projected revenue streams. Intangible assets with definite lives are reviewed for impairment if indicators of impairment arise. The Company does not have any intangible assets with indefinite useful lives. Goodwill represents the excess of costs over fair value of assets of businesses acquired. The Company reviews goodwill for impairment annually as of December 31 and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable in accordance with Accounting Standard Intangibles - Goodwill and Other (Topic 350): Testing Goodwill for Impairment, Intangibles — Goodwill and Other ASU 2011-08 permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. Under ASU 2011-08, an entity is not required to perform step one of the goodwill impairment test for a reporting unit if it is more likely than not that its fair value is greater than its carrying amount. For the annual goodwill impairment test as of December 31, 2016, the Company performed a quantitative step one goodwill impairment test and concluded that the fair values of each of the reporting units exceeded their respective carrying values.
Foreign currency translation	Foreign currency translation Balance sheet accounts for foreign operations are translated at the exchange rate as of the balance sheet date, and income statement accounts are translated at the average exchange rate for the year. The resulting translation adjustments are included in accumulated other comprehensive loss. Transaction gains and losses resulting from changes in exchange rates are recorded in our statements of operations in the year in which they occur. For the years ended December 31, 2016, and 2015, foreign currency transaction losses were approximately $69,000 and $34,000, respectively.
Accrued warranty	Accrued warranty For contracts that contain a warranty provision, the Company provides an accrual for estimated future warranty costs based on historical experience and projected claims. The Company's contracts may contain warranty provisions from one to five years. The current portion of the accrued warranty is presented separately on the Consolidated Balance Sheets within Current liabilities whereas the noncurrent portion is included in Other liabilities. The activity in the accrued warranty accounts is as follows: (in thousands) As of and for the years ended December 31, 2016 2015 Beginning balance $ 1,614 $ 1,456 Current year provision 355 626 Current year claims (467 ) (455 ) Currency adjustment (24 ) (13 ) Ending balance $ 1,478 $ 1,614
Income taxes	Income taxes Income taxes are provided under the asset and liability method. Under this method, deferred income taxes are determined based on the differences between the consolidated financial statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amounts expected to be realized. A provision is made for the Company's current liability for federal, state and foreign income taxes and the change in the Company's deferred income tax assets and liabilities. We establish accruals for uncertain tax positions taken or expected to be taken in a tax return when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities that have full knowledge of all relevant information. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Favorable or unfavorable adjustment of the accrual for any particular issue would be recognized as an increase or decrease to income tax expense in the period of a change in facts and circumstances. Interest and penalties related to income taxes are accounted for as income tax expense.
Stock-based compensation	Stock-based compensation Compensation expense related to share based awards is recognized on a pro rata straight-line basis based on the value of share awards that are scheduled to vest during the requisite service period. During the years ended December 31, 2016 and 2015, the Company recognized $1.6 million and $0.5 million, respectively, of pre-tax stock-based compensation expense under the fair value method. During 2016, the Company recognized approximately $151,000 of compensation expense related to cash-settled RSUs.
Income (loss) per share	Earnings (loss) per share Basic earnings (loss) per share is based on the weighted average number of outstanding common shares for the period. Diluted earnings (loss) per share adjusts the weighted average shares outstanding for the potential dilution that could occur if outstanding vested stock options were exercised. Basic and diluted earnings (loss) per share is based on the weighted average number of outstanding shares for the period. The number of common shares and common share equivalents used in the determination of basic and diluted loss per share were as follows: (in thousands, except for per share data) Years ended December 31, 2016 2015 Numerator: Net income (loss) $ 1,422 $ (4,705 ) Denominator: Weighted-average shares outstanding for basic income (loss) per share 18,218,681 17,892,891 Effect of dilutive securities: Stock options and restricted stock units 293,585 - Adjusted weighted-average shares outstanding and assumed conversions for diluted income (loss) per share 18,512,266 17,892,891 Shares related to dilutive securities excluded because inclusion would be anti-dilutive 677,964 2,492,710 Conversion of certain outstanding stock options was not assumed for the years ended December 31, 2016 and 2015 because the impact would have been anti-dilutive.
Significant Customers and Concentration of credit risk	Significant customers and concentration of credit risk We have a concentration of revenue from an individual customer, which accounted for approximately 10.2% and 15.9% of our consolidated revenue for the years ended December 31, 2016 and 2015, respectively. No other individual customer accounted for more than 10% of our consolidated revenue in 2016 or 2015.
Fair values of financial instruments	Fair values of financial instruments The carrying amounts of current assets and current liabilities reported in the consolidated balance sheets approximate fair value due to their short term duration.
Contingent consideration for business acquisitions	Contingent consideration for business acquisitions Acquisitions may include contingent consideration payments based on future financial measures of an acquired company. Contingent consideration is required to be recognized at fair value as of the acquisition date. The Company estimates the fair value of these liabilities based on financial projections of the acquired companies and estimated probabilities of achievement. At each reporting date, the contingent consideration obligation is revalued to estimated fair value and changes in fair value subsequent to the acquisition are reflected in income or expense in the consolidated statements of operations, and could cause a material impact to our operating results. Changes in the fair value of contingent consideration obligations may result from changes in discount periods and rates, changes in the timing and amount of revenue and/or earnings estimates and changes in probability assumptions with respect to the likelihood of achieving the various earn-out criteria.
Derivative instruments	Derivative instruments The Company utilizes forward foreign currency exchange contracts to manage market risks associated with the fluctuations in foreign currency exchange rates. It is the Company's policy to use such derivative financial instruments to protect against market risk arising in the normal course of business in order to reduce the impact of these exposures. The Company minimizes credit exposure by limiting counterparties to nationally recognized financial institutions. As of December 31, 2016, the Company had foreign exchange contracts outstanding of approximately 281.4 million Japanese Yen, 0.6 million Australian Dollars, 0.5 million Canadian Dollars, and 0.1 million Euro. At December 31, 2015, the Company had foreign exchange contracts outstanding of approximately 2.1 million Euro, 1.3 million Canadian Dollars, 0.5 million Pounds Sterling and 0.4 million Australian Dollars at fixed rates. The contracts expire on various dates through December 2018. The Company had not designated the foreign exchange contracts as hedges and had recorded the estimated fair value of the contracts in the consolidated balance sheet as follows: December 31, (in thousands) 2016 2015 Asset derivatives Prepaid expenses and other current assets $ 57 $ 115 Other assets 84 6 141 121 Liability derivatives Other current liabilities (20 ) (57 ) (20 ) (57 ) Net fair value $ 121 $ 64 The changes in the fair value of the foreign exchange contracts are included in gain (loss) on derivative instruments, net in the consolidated statements of operations. The foreign currency denominated trade receivables, unbilled receivables, billings in excess of revenue earned and subcontractor accruals that are related to the outstanding foreign exchange contracts are remeasured at the end of each period into the functional currency using the current exchange rate at the end of the period. The gain or loss resulting from such remeasurement is also included in gain (loss) on derivative instruments net in the consolidated statements of operations. For the years ended December 31, 2016 and 2015, the Company recognized a loss on its derivative instruments net as outlined below: Years ended December 31, (in thousands) 2016 2015 Foreign exchange contracts- change in fair value $ 51 $ (6 ) Remeasurement of related contract receivables and billings in excess of revenue earned (69 ) (34 ) $ (18 ) $ (40 )
Reclassification	Reclassifications Certain prior year amounts have been reclassified to conform with the current year presentation. Subcontractor payables have been reclassified on the Consolidated Balance Sheets from Accounts payable to Accrued expenses. In addition, the Company reclassified research and development costs from Selling, general and administrative expenses and presented them as a separate caption within Operating expenses on the Consolidated Statement of Operations. The Company also reclassified the current portion of deferred taxes to noncurrent within Other assets and Other liabilities on the Consolidated Balance Sheets.
New accounting standards	Accounting pronouncements recently adopted In November 2015, the Financial Accounting Standards Board (FASB) issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Accounting pronouncements not yet adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers In July 2015, FASB issued ASU 2015-11, Simplifying the Measurement of Inventory . ASU 2015-11 requires that an entity measure inventory at the lower of cost and net realizable value. This ASU does not apply to inventory measured using last-in, first-out. ASU 2015-11 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. We do not expect the new standard to have a significant impact on our consolidated financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Topic 718: Improvements to Employee Share Based Accounting In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the definition of a Business , which amends the current definition of a business. Under ASU 2017-01, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contributes to the ability to create outputs. ASU 2017-01 further states that when substantially all of the fair value of gross assets acquitted is concentrated in a single asset (or a group of similar assets), the assets acquired would not represent a business. The new guidance also narrows the definition of the term "outputs" to be consistent with how it is described in Topic 606, Revenue from Contracts with Customers . The changes to the definition of a business will likely result in more acquisitions being accounted for as asset acquisitions. ASU 2017-01 is effective for acquisitions commencing on or after June 30, 2019, with early adoption permitted. Adoption of this guidance will be applied prospectively on or after the effective date. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other . ASU 2017-04 simplifies the accounting for goodwill impairment by eliminating Step 2 of the current goodwill impairment test, which required a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which the reporting unit's carrying value exceeds its fair value, limited to the carrying value of the goodwill. ASU 2017-04 is effective for financial statements issued for fiscal years, and interim periods beginning after December 15, 2019.
