Recent Accounting Standards

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Standards	Recent Accounting Standards Accounting Standard Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation (Topic 718) (" ASU 2016-09" ), which simplifies several areas of accounting for share-based compensation arrangements. Upon adoption, ASU 2016-09 requires that excess tax benefits or deficiencies for share-based payments be recorded as income tax expense or benefit and reflected within operating cash flows rather than being recorded within equity and reflected within financing cash flows. The standard also requires companies to make an accounting policy election on whether to account for forfeitures on share-based payments by 1) recognizing forfeitures as they occur; or 2) estimating the number of awards expected to be forfeited and periodically adjusting the estimate, as was previously required. The standard is effective for annual and interim reporting periods of public companies beginning after December 15, 2016, although early adoption was permitted. We adopted ASU 2016-09 on January 1, 2017 and elected to make an accounting policy change to recognize forfeitures as they occur. The impact of adoption on the condensed consolidated balance sheet was a cumulative-effect adjustment of $0.1 million , decreasing opening retained earnings. We recognized an income tax benefit of $ 0.2 million relating to excess tax benefits on stock-based compensation awards during the nine months ended September 30, 2017 and could experience volatility in our effective income tax rate in the future as a result of this accounting change. We also elected to prospectively apply the change in presentation on the statement of cash flows and did not reclassify excess tax benefits on stock-based compensation from financing to operating cash flows for the prior period presented. Accounting Standards Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for public companies for annual and interim periods beginning after December 15, 2017, which requires us to adopt the standard in the first quarter of 2018. Companies can elect to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with a cumulative effect adjustment recognized at the date of adoption. We plan to adopt the standard effective January 1, 2018 using the modified retrospective approach with a cumulative effect adjustment at the date of adoption. We have performed an assessment of the impact of the ASU and developed a transition plan, including necessary changes to policies, processes and internal controls. While our assessment is substantially complete, we are currently still evaluating the quantitative impact of the changes to our financial statements and preparing for the expanded disclosure requirements. Based on our assessment to date, we believe the new standard will result in a change in revenue recognition on certain fixed price projects from a proportional performance method, where revenue is currently recognized over contract performance, to a point in time method, where revenue would be recognized upon completion of our performance obligations. This change could result in a shift in the timing of revenue recognition, causing quarter to quarter revenue fluctuations, however, an estimate of the magnitude of the impact to our consolidated financial statements cannot be made at this time. In February 2016, the FASB issued ASU No. 2016-02, Leases . This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet as a right-of-use asset and a lease liability. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. We believe adoption of this standard will have a significant impact on our consolidated balance sheets because we will need to recognize substantially all of our operating leases as right-of-use assets and lease liabilities on our balance sheet. Although we have not completed our assessment, we do not expect the adoption of ASU 2016-02 to materially change the recognition and measurement of lease expense within the consolidated statements of operations. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment . The standard will remove step 2 from the goodwill impairment test. Under the ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating ASU 2017-04 and the impact of its adoption on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities . The standard will ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. ASU 2017-12 is effective for public companies for annual reporting periods beginning after December 15, 2018 but early adoption is permitted. We are currently evaluating ASU 2017-12 and the impact of its adoption on our consolidated financial statements.

Risks and Uncertainties [Abstract]
Significant Customers & Concentration of Credit Risk	Significant Customers & Concentration of Credit Risk We have a market concentration of revenue in both the automotive sector and financial services & insurance sector. Revenue from the automotive industry accounted for approximately 22% of our consolidated revenue for both of the nine -month periods ended September 30, 2017 and 2016 . In addition, we have a concentration of revenue from a single automotive customer, which accounted for approximately 13% of our consolidated revenue for both of the nine -month periods ended September 30, 2017 and 2016 . As of September 30, 2017 , accounts receivable from a single automotive customer totaled $10.9 million , or 11% , of our consolidated accounts receivable balance. Revenue from the financial services & insurance industry accounted for approximately 20% and 21% of our consolidated revenue for the nine months ended September 30, 2017 and 2016 , respectively. In addition, we have a concentration of revenue from a single financial services customer, which accounted for approximately 14% and 15% of our consolidated revenue for the nine months ended September 30, 2017 and 2016 , respectively. As of September 30, 2017 , billed and unbilled accounts receivable from a single financial services customer totaled $ 28.3 million , or 19% , of our consolidated accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts balances. No other single customer accounted for more than 10% of our consolidated revenue for the nine months ended September 30, 2017 or 2016 or consolidated accounts receivable balance as of September 30, 2017 .

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share (EPS) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Our dilutive common stock equivalent shares consist of stock options and restricted stock units computed under the treasury stock method, using the average market price during the period. Performance-based restricted stock unit awards are included in the computation of diluted shares based on the probable outcome of the underlying performance conditions being achieved. The following table presents instruments which were not dilutive and were excluded from the computation of diluted EPS in each period, as well as the dilutive common stock equivalent shares which were included in the computation of diluted EPS: Three Months Ended Nine Months Ended 2017 2016 2017 2016 (In thousands) Non-dilutive instruments — — 17 59 Dilutive common stock equivalents 146 101 120 106

Business Combinations [Abstract]
Acquisitions	Acquisitions YouTrain On August 31, 2017, we acquired the entire share capital of YouTrain Limited ("YouTrain"), an independent training company delivering IT, digital and life sciences skills training in Scotland and North West England. The upfront purchase price was $4.9 million which was paid in cash at closing. In addition, the purchase price is subject to a completion accounts adjustment which is expected to be settled during the fourth quarter of 2017. The preliminary purchase price allocation is subject to change and is expected to be finalized in the fourth quarter of 2017. The goodwill recognized is due to the expected synergies from combining the operations of the acquiree with the Company. None of the goodwill recorded for financial statement purposes is deductible for tax purposes. The acquired YouTrain business is included in the Learning Solutions segment and the results of its operations have been included in the consolidated financial statements beginning September 1, 2017. The pro-forma impact of the acquisition is not material to our results of operations. The acquired YouTrain business is included in our United Kingdom subsidiary and its functional currency is the British Pound Sterling. The purchase price allocation below was translated into U.S. dollars based on the exchange rate in effect on the date of acquisition. The following table summarizes the fair value of the purchase price and purchase price allocation for the acquisition (dollars in thousands). Cash purchase price $ 4,898 Estimated completion accounts payment 180 Total purchase price $ 5,078 Amortization Purchase price allocation: Period Cash $ 673 Accounts receivable and other current assets 248 Fixed assets 215 Customer-related intangible assets 1,313 5 years Goodwill 3,228 Total assets 5,677 Accounts payable and accrued expenses 322 Billings in excess of costs and estimated 28 Deferred tax liability 249 Total liabilities 599 Net assets acquired $ 5,078 CLS Performance Solutions Limited On August 31, 2017, we acquired the business and certain assets of CLS Performance Solutions Limited ("CLS"), an independent provider of Enterprise Resource Planning (ERP) end user adoption and training services in the United Kingdom. The upfront purchase price was $0.4 million which was paid in cash at closing. In addition, the purchase agreement requires up to an additional $2.1 million of consideration contingent upon the achievement of certain earnings targets during the twelve-month period following the completion of the acquisition. The total estimated fair value of the purchase consideration was $1.3 million which consists primarily of intangible assets of $0.3 million being amortized over three years from the acquisition date and goodwill of $1.0 million . The goodwill recognized is due to the expected synergies from combining the operations of the acquiree with the Company. None of the goodwill recorded for financial statement purposes is deductible for tax purposes. The acquired CLS business is included in the Performance Readiness Solutions segment, and the results of its operations have been included in the consolidated financial statements beginning September 1, 2017. The pro-forma impact of the acquisition is not material to our results of operations. McKinney Rogers On February 1, 2017, we acquired the business and certain assets of McKinney Rogers, a provider of strategic consulting services with offices in New York and London. This acquisition will expand our solutions offerings, giving us the ability to leverage McKinney Rogers' intellectual property and consulting methodologies to help our global client base meet strategic business goals. The upfront purchase price was $3.3 million in cash. In addition, the purchase agreement requires up to an additional $18.0 million of consideration, $6.0 million of which was contingent upon the achievement of certain earnings targets during the five -month period ended April 30, 2017 and $12.0 million of which is contingent upon the achievement of certain earnings targets during the three twelve-month periods following completion of the acquisition. In July 2017, we paid the seller $1.0 million in respect of the contingent consideration for the five-month period ended April 30, 2017. The goodwill recognized is due to the expected synergies from combining the operations of the acquiree with the Company. We expect that all of the goodwill recorded for financial statement purposes will be deductible for tax purposes, except that the contingent consideration is only deductible when paid. If the actual contingent consideration payments are less than the estimated fair value as of the acquisition date, a portion of goodwill will not be deductible for tax purposes. The acquired McKinney Rogers business is included in the Performance Readiness Solutions segment, and the results of its operations have been included in the consolidated financial statements beginning February 1, 2017. The pro-forma impact of the acquisition is not material to our results of operations. The following table summarizes the fair value of the purchase price and purchase price allocation for the acquisition (dollars in thousands).

This acquisition strengthens our eLearning development capabilities, allowing us to better serve our customer base with the latest digital learning solutions. The upfront purchase price was $3.2 million in cash. In addition, the purchase agreement requires up to an additional $0.3 million of consideration, contingent upon the achievement of an earnings target during the twelve-month period following completion of the acquisition, plus a percentage of any earnings in excess of the specified earnings target. The goodwill recognized is due to the expected synergies from combining the operations of the acquiree with the Company. We expect that all of the goodwill recorded for financial statement purposes will be deductible for tax purposes, except that the contingent consideration is only deductible when paid. If the actual contingent consideration payments are less than the estimated fair value as of the acquisition date, a portion of goodwill will not be deductible for tax purposes. The acquired Emantras business is included in the Learning Solutions segment, and the results of its operations have been included in the consolidated financial statements beginning April 1, 2017. The pro-forma impact of the acquisition is not material to our results of operations. The following table summarizes the fair value of the purchase price and purchase price allocation for the acquisition (dollars in thousands). Cash purchase price $ 3,191 Fair value of contingent consideration 220 Total purchase price $ 3,411 Amortization Purchase price allocation: Period Fixed assets $ 50 Customer-related intangible assets 818 4 years Goodwill 3,156 Total assets 4,024 Accrued expenses 558 Billings in excess of costs and estimated 55 Total liabilities 613 Net assets acquired $ 3,411 Contingent Consideration Accounting Standards Codification (“ASC”) Topic 805 requires that contingent consideration be recognized at fair value on the acquisition date and be re-measured each reporting period with subsequent adjustments recognized in the condensed consolidated statement of operations. We estimate the fair value of contingent consideration liabilities using an appropriate valuation methodology, typically either an income-based approach or a simulation model, such as the Monte Carlo model, depending on the structure of the contingent consideration arrangement. Contingent consideration is valued using significant inputs that are not observable in the market which are defined as Level 3 inputs pursuant to fair value measurement accounting. We believe our estimates and assumptions are reasonable; however, there is significant judgment involved. At each reporting date, the contingent consideration obligation is revalued to estimated fair value, and changes in fair value subsequent to the acquisitions are reflected in income or expense in the condensed consolidated statements of operations, and could cause a material impact to, and volatility in, our operating results. Changes in the fair value of contingent consideration obligations may result from changes in discount periods and rates and changes in the timing and amount of revenue and/or earnings projections. Below is a summary of the potential maximum contingent consideration we may be required to pay in connection with completed acquisitions as of September 30, 2017 (dollars in thousands): Acquisition: Original range of potential undiscounted payments As of September 30, 2017 Maximum contingent consideration due in 2017 2018 2019-2020 Total Maverick $0 - $10,000 $ 5,000 $ 5,000 $ — $ 10,000 McKinney Rogers $0 - $18,000 967 4,000 8,000 12,967 Emantras — * — — CLS $0 - $2,132 — 2,132 — 2,132 $ 5,967 $ 11,132 $ 8,000 $ 25,099 * There is no maximum contingent consideration payable to the seller.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation We recognize compensation expense for stock-based compensation awards issued to employees that are expected to vest. Compensation cost is based on the fair value of awards as of the grant date. The following table summarizes the pre-tax stock-based compensation expense included in reported net income (in thousands): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Non-qualified stock options $ 1 $ 6 $ 6 $ 81 Restricted stock units 891 801 2,569 2,011 Board of Directors stock grants 93 86 248 233 Total stock-based compensation expense $ 985 $ 893 $ 2,823 $ 2,325 Pursuant to our 2011 Stock Incentive Plan (the “2011 Plan”), we may grant awards of non-qualified stock options, incentive stock options, restricted stock, stock units, performance shares, performance units and other incentives payable in cash or in shares of our common stock to officers, employees or members of the Board of Directors. As of September 30, 2017 , we had non-qualified stock options and restricted stock units outstanding under these plans as discussed below. Non-Qualified Stock Options Summarized information for the Company’s non-qualified stock options is as follows: Number of options Weighted average exercise price Weighted average remaining contractual term Aggregate intrinsic value Stock Options Outstanding at December 31, 2016 67,550 $ 15.34 Granted — — Exercised (59,050 ) 15.11 Forfeited (100 ) 19.38 Expired (400 ) 19.38 Outstanding at September 30, 2017 8,000 $ 16.80 0.67 $ 112,000 Exercisable at September 30, 2017 7,400 $ 16.59 0.64 $ 106,000 Restricted Stock Units In addition to stock options, we issue restricted stock units to key employees and members of the Board of Directors. The stock units vest to the recipients at various dates, up to five years , based on fulfilling service requirements. We recognize the value of the market price of the underlying stock on the date of grant as compensation expense over the requisite service period. Upon vesting, the stock units are settled in shares of our common stock. Summarized share information for our restricted stock units is as follows: Nine Months Ended September 30, 2017 Weighted average grant date fair value (In shares) (In dollars) Outstanding and unvested, beginning of period 207,016 $ 29.85 Granted 55,350 24.62 Vested (41,668 ) 20.61 Forfeited (4,947 ) 25.21 Outstanding and unvested, end of period 215,751 $ 30.40 Performance Stock Units We issue performance-based stock units to certain executives under a long-term incentive program. Under the program, a target level of equity compensation is set for each officer. The total equity compensation is divided into performance-based and time-based restricted stock units. Under the program, the Compensation Committee sets the performance-based goals within the first 90 days of each year. Vesting of performance-based stock units (PSU's) is contingent upon the employee's continued employment and the Company's achievement of certain performance goals during a three-year performance period. The performance goals are established by the Compensation Committee for a three-year performance period based on financial targets, including an average annual return on invested capital ("ROIC") and average annual growth in earnings before interest, taxes, depreciation and amortization (adjusted to exclude the effect of acquisitions, dispositions, and certain other nonrecurring or extraordinary items) ("Adjusted EBITDA"). We recognize compensation expense for PSU's on a straight line basis over the performance period based on the probable outcome of achievement of the financial targets. At the end of each reporting period, we estimate the number of PSU's expected to vest, based on the probability and extent to which the performance goals will be met, and take into account these estimates when calculating the expense for the period. If the number of shares expected to be earned changes during the performance period, we will make a cumulative adjustment to compensation expense based on the revised number of shares expected to be earned. Summarized share information for our performance-based restricted stock units is as follows: Nine Months Ended September 30, 2017 Weighted average grant date fair value (In shares) (In dollars) Outstanding and unvested, beginning of period 124,394 $ 31.08 Granted 104,590 23.65 Vested — — Forfeited — — Outstanding and unvested, end of period 228,984 $ 27.69

Debt Disclosure [Abstract]
Debt and Financial Instruments	Debt and Financial Instruments On December 15, 2016, we entered into a Fifth Amended and Restated Financing and Security Agreement (the “Credit Agreement”). The Credit Agreement provides for a revolving credit facility up to a maximum principal amount of $100 million expiring on December 31, 2021 and for a term loan in the principal amount of $40 million maturing on April 30, 2020 . The Credit Agreement is secured by substantially all of our assets. The maximum interest rate on the Credit Agreement is the daily one-month LIBOR market index rate (for borrowings in Dollars and Sterling) or the daily one month EURIBOR (for borrowings in Euros) plus 2.50% . Based on our financial performance, the interest rate can be reduced to a minimum rate of the daily one-month LIBOR market index rate plus 1.25% , with the rate being determined based on our maximum leverage ratio for the preceding four quarters. Each unpaid advance on the revolving loan will bear interest until repaid. The term loan is payable in monthly installments of principal in the amount of $1.0 million plus applicable interest, beginning on January 1, 2017. We may prepay the term loan or the revolving loan, in whole or in part, at any time without premium or penalty, subject to certain conditions. Amounts repaid or prepaid on the term loan may not be reborrowed. The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict our and our subsidiaries’ (subject to certain exceptions) ability to, among other things, grant liens, make investments, incur indebtedness, merge or consolidate, dispose of assets or make acquisitions. We are also required to maintain compliance with a minimum fixed charge coverage ratio and a maximum leverage ratio. We were in compliance with all of the financial covenants under the Credit Agreement as of September 30, 2017 . As of September 30, 2017 , our total long-term debt outstanding under the term loan was $31.0 million . In addition, there were $27.5 million of borrowings outstanding and $67.2 million of available borrowings under the Credit Agreement. For the nine months ended September 30, 2017 , the weighted average interest rate on our borrowings was 2.8% . In March 2017, we entered into an interest rate swap agreement which effectively fixed our interest rate on the remaining $37 million outstanding on our term loan to a fixed LIBOR of 1.59% plus the applicable margin under the Credit Agreement. We have designated the interest rate swap, which expires on April 1, 2020, as a cash flow hedge and have applied hedge accounting. The fair value of the derivative liability associated with the interest rate swap was less than $0.1 million as of September 30, 2017 and is included in other liabilities on the condensed consolidated balance sheet. The derivative liability is classified within Level 2 of the fair value hierarchy in which fair value is measured using quoted prices in active markets for similar assets and liabilities. In April 2017, we entered into an interest rate cap agreement and paid a premium of $0.5 million which caps the daily one-month LIBOR at 2.0% for an aggregate notional amount of $20.0 million of our variable rate debt under our credit facility. The interest rate cap agreement matures on December 31, 2021. We have designated the interest rate cap as a cash flow hedge and have applied hedge accounting. The fair value of the derivative asset associated with the interest rate cap was $0.2 million as of September 30, 2017 and is included in other assets on the condensed consolidated balance sheet. The derivative asset is classified within Level 2 of the fair value hierarchy in which fair value is measured using quoted prices in active markets for similar assets and liabilities.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $5.2 million , or an effective income tax rate of 28.3% , for the nine months ended September 30, 2017 compared to $8.1 million , or an effective income tax rate of 37.4% , for the nine months ended September 30, 2016 . The decrease in the effective income tax rate in 2017 compared to 2016 is primarily due to a change in the mix of taxable income from higher taxing jurisdictions to lower taxing jurisdictions. Income tax expense for the quarterly periods is based on an estimated annual effective tax rate which includes the U.S. federal, state and local, and non-U.S. statutory rates, permanent differences, and other items that may have an impact on income tax expense. An uncertain tax position taken or expected to be taken in a tax return is recognized in the financial statements 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. Interest and penalties related to income taxes are accounted for as income tax expense. As of September 30, 2017 , we had no uncertain tax positions reflected on our consolidated balance sheet. The Company files income tax returns in U.S. federal, state and local jurisdictions, and various non-U.S. jurisdictions, and is subject to audit by tax authorities in those jurisdictions. Tax years 2013 through 2016 remain open to examination by these tax jurisdictions, and earlier years remain open to examination in certain of these jurisdictions which have longer statutes of limitations.

Recent Accounting Standards (Po

Recent Accounting Standards (Policy)	9 Months Ended
	Sep. 30, 2017
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	Accounting Standard Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation (Topic 718) (" ASU 2016-09" ), which simplifies several areas of accounting for share-based compensation arrangements. Upon adoption, ASU 2016-09 requires that excess tax benefits or deficiencies for share-based payments be recorded as income tax expense or benefit and reflected within operating cash flows rather than being recorded within equity and reflected within financing cash flows. The standard also requires companies to make an accounting policy election on whether to account for forfeitures on share-based payments by 1) recognizing forfeitures as they occur; or 2) estimating the number of awards expected to be forfeited and periodically adjusting the estimate, as was previously required. The standard is effective for annual and interim reporting periods of public companies beginning after December 15, 2016, although early adoption was permitted. We adopted ASU 2016-09 on January 1, 2017 and elected to make an accounting policy change to recognize forfeitures as they occur. The impact of adoption on the condensed consolidated balance sheet was a cumulative-effect adjustment of $0.1 million , decreasing opening retained earnings. We recognized an income tax benefit of $ 0.2 million relating to excess tax benefits on stock-based compensation awards during the nine months ended September 30, 2017 and could experience volatility in our effective income tax rate in the future as a result of this accounting change. We also elected to prospectively apply the change in presentation on the statement of cash flows and did not reclassify excess tax benefits on stock-based compensation from financing to operating cash flows for the prior period presented. Accounting Standards Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The ASU’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. ASU 2014-09 is effective for public companies for annual and interim periods beginning after December 15, 2017, which requires us to adopt the standard in the first quarter of 2018. Companies can elect to apply the provisions of ASU 2014-09 either retrospectively to each prior reporting period presented or retrospectively with a cumulative effect adjustment recognized at the date of adoption. We plan to adopt the standard effective January 1, 2018 using the modified retrospective approach with a cumulative effect adjustment at the date of adoption. We have performed an assessment of the impact of the ASU and developed a transition plan, including necessary changes to policies, processes and internal controls. While our assessment is substantially complete, we are currently still evaluating the quantitative impact of the changes to our financial statements and preparing for the expanded disclosure requirements. Based on our assessment to date, we believe the new standard will result in a change in revenue recognition on certain fixed price projects from a proportional performance method, where revenue is currently recognized over contract performance, to a point in time method, where revenue would be recognized upon completion of our performance obligations. This change could result in a shift in the timing of revenue recognition, causing quarter to quarter revenue fluctuations, however, an estimate of the magnitude of the impact to our consolidated financial statements cannot be made at this time. In February 2016, the FASB issued ASU No. 2016-02, Leases . This standard will require all leases with durations greater than twelve months to be recognized on the balance sheet as a right-of-use asset and a lease liability. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. We believe adoption of this standard will have a significant impact on our consolidated balance sheets because we will need to recognize substantially all of our operating leases as right-of-use assets and lease liabilities on our balance sheet. Although we have not completed our assessment, we do not expect the adoption of ASU 2016-02 to materially change the recognition and measurement of lease expense within the consolidated statements of operations. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment . The standard will remove step 2 from the goodwill impairment test. Under the ASU, an entity should perform its annual goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for public companies for annual reporting periods beginning after December 15, 2019. Early adoption is permitted for goodwill impairment tests performed on testing dates after January 1, 2017. We are currently evaluating ASU 2017-04 and the impact of its adoption on our consolidated financial statements.
