Notes to Financial Statements
Significant Accounting Policies [Text Block]	NOTE 2 —SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Revenue Recognition The Company recognizes revenue when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable, and collectability is reasonably assured. The Company enters into three • Time-and-Materials Contracts. Revenue for time-and-materials contracts is recorded on the basis of allowable labor hours worked multiplied by the contract-defined billing rates, plus the costs of other items used in the performance of the contract. Profits and losses on time-and-materials contracts result from the difference between the cost of services performed and the contract-defined billing rates for these services. • Cost-Based Contracts . • Fixed-Price Contracts . may one • Proportional Performance: Revenue on certain fixed-price contracts is recognized based on proportional performance when the provision of services extends beyond an accounting period with more than one progress towards completion can be measured based on a reliable output or input. Under this method, revenue is recorded each period based upon certain contract performance input measures incurred (labor hours, labor costs, or total costs) or output measures completed, expressed as a proportion of a total project estimate. Progress on a contract is monitored regularly to ensure that revenue recognized reflects project status. When hours or costs incurred are used as the basis for revenue recognition, the hours or costs incurred represent a reasonable surrogate for output measures of contract performance, including the presentation of deliverables to the client. Clients are obligated to pay as services are performed, and in the event that a client cancels the contract, payment for services performed through the date of cancellation is typically negotiated with the client. • Specific Performance : hen the services to be performed consist of a single act, revenue is recognized at the time the act is performed or at the completion of the single service. • Straight-Line : When services are performed or are expected to be performed consistently throughout an arrangement, or when the Company is compensated on a retainer or fixed-fee basis, revenue is recognized ratably over the period benefited. • Completed Contract : Revenue and costs on certain fixed-price contracts are recognized at completion if the final act is so significant to the arrangement that value is deemed to be transferred only at completion. Revenue recognition requires the Company to use judgment relative to assessing risks, estimating contract revenue and costs or other variables, and making assumptions for scheduling and technical issues. Due to the size and nature of many of the Company’s contracts, the estimation of revenue and estimates at completion can be complicated and are subject to many variables. Contract costs include labor, subcontractor costs, and other direct costs, as well as an allocation of indirect costs. At times, the Company must also make assumptions regarding the length of time to complete the contract because costs include expected increases in wages, prices for subcontractors, and other direct costs. From time to time, facts develop that require the Company to revise its estimated total costs or hours and thus the associated revenue on a contract. To the extent that a revised estimate affects contract profit or revenue previously recognized, the Company records the cumulative effect of the revision in the period in which the facts requiring the revision become known. A provision for the full amount of an anticipated loss on any type of contract is recognized in the period in which it becomes probable and can be reasonably estimated. As a result, operating results could be affected by revisions to prior accounting estimates. C ontractual arrangements are evaluated to assess whether revenue should be recognized on a gross versus net basis. Management’s assessment when determining gross versus net revenue recognition is based on several factors, such as whether the Company serves as the primary service provider, has autonomy in selecting subcontractors, or has credit risk, all of which are primary indicators that the Company serves as the principal to the transaction. In such cases, revenue is recognized on a gross basis. When such indicators are not present and the Company is primarily functioning as an agent under an arrangement, revenue is recognized on a net basis. Payments to the Company on cost-based contracts with the federal government are provisional payments subject to adjustment upon audit by the government. Such audits have been finalized through December 31, 2007, The Company generates invoices to clients in accordance with the terms of the applicable contract, which may the Company included in the cost of revenue. The Company records revenue net of taxes collected from customers to be remitted to governmental authorities. The Company may documents. It has a review process for approving any such work. Revenue associated with such work is recognized only when it can be reliably estimated and realization is probable. The Company bases its estimates on a variety of factors, including previous experiences with the client, communications with the client regarding funding status, and its knowledge of available funding for the contract. Cash and Cash Equivalents The Company considers cash on deposit and all highly liquid investments with original maturities of three when purchased to be cash and cash equivalents. Restricted Cash The Company has restricted cash representing amounts held in escrow accounts and/or not readily available due to contractual restrictions. Allowance for Doubtful Accounts The Company considers a number of factors in its estimate of allowance for doubtful accounts, including the customer ’s financial condition, historical collection experience, and other factors that may Property and Equipment Property and equipment are carried at cost and are depreciated using the straight-line method over their estimated useful lives, which range from two seven Goodwill and Other Intangible Assets The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired , less liabilities assumed, based upon their respective fair values, with the excess recorded as goodwill. Goodwill represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead are reviewed for impairment annually, or more frequently if impairment indicators arise. Intangible assets with estimable useful lives are amortized over such lives and reviewed for impairment if impairment indicators arise. Impairment The Company performs its annual goodwill impairment review as of September 30 one September 30, 2016, may two The Company ’s qualitative analysis as of September 30, 2016, one two 2016. no September 30, 2016. no The Company is required to review long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less cost to sell. Capitalized Software The Company capitalizes eligible costs to develop enhancements and upgrades to internal-use software that are incurred subsequent to the preliminary project stage. Amortization expense is recorded on a straight-line basis over the expected economic life, typically three five December 31, 2016, 2015, 2014, Deferred Rent The Company recognizes rent expense on a straight-line basis over the non-cancellable term of each lease, including renewal option periods when renewal is reasonably assured or executed. Lease incentives or abatements received at or near the inception of leases are accrued and amortized ratably over the life of the lease. Stock-based Compensation The Company recognizes stock-based compensation expense related to share-based payments to employees, including grants of employee stock options, restricted stock awards, restricted stock units (“RSUs”) , and cash-settled restricted stock units (“CSRSUs”) on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes expense for performance-based share awards (“PSAs”), which have a performance condition and a market condition, on a straight-line basis over the performance period. Non-employee director awards do not include vesting conditions and therefore are expensed when issued. Stock-based c ompensation expense is based on the estimated fair value of these instruments and the estimated number of shares the Company ultimately expects will vest. The Company estimates the rate of future forfeitures based on factors such as historical experience and employee class. In addition, the estimation of PSAs that will ultimately vest requires judgment based on performance conditions. Changes to these estimates are recorded as a cumulative adjustment in the period estimates are revised. The fair value of stock options, restricted stock awards, RSUs , PSAs, and non-employee director awards is estimated based on the fair value of a share of common stock at the grant date. The Company has elected to use the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The fair value of PSAs is estimated using a Monte Carlo simulation model. CSRSUs are settled only in cash payments. The cash payment is based on the fair value of the Company ’s stock price at the vesting date, calculated by multiplying the number of CSRSUs vested by the Company’s closing stock price on the vesting date, subject to a maximum payment cap and a minimum payment floor. The Company treats these awards as liability-classified awards, and therefore accounts for them at fair value estimated based on the closing price of the Company’s stock at the reporting date. Other Comprehensive (Loss) Income Other comprehensive (loss) income represents foreign currency translation adjustments arising from the use of differing exchange rates from period to period and the gain on the sale of an interest rate hedge agreement. The financial positions and results of operations of the Company’s foreign subsidiaries are based on the local currency as the functional currency and are translated to U.S. dollars for financial reporting purposes. Assets and liabilities of the subsidiaries are translated at the exchange rate in effect at each period-end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Translation adjustments are included in accumulated other comprehensive (loss) income in stockholders’ equity in the Company’s consolidated balance sheets. The activity included in other comprehensive (loss) income in the Company’s consolidated statements of comprehensive income for each period reported is summarized below.

Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The Company evaluates its ability to benefit from all deferred tax assets and establishes valuation allowances for amounts it believes are not more likely than not to be realizable. For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements. Penalties, if probable and reasonably estimable, and interest expense related to uncertain tax positions are not recognized as a component of income tax expense but recorded separately in indirect expenses. Derivative Instruments Derivative instruments designated as cash flow hedges are recorded on the consolidated balance sheet at fair value , at the reporting date, and the effective portion of the hedge is recorded in other comprehensive (loss) income on the consolidated statement of comprehensive income and reclassified to earnings in the period that the hedged instruments affect earnings.

Treasury Shares Treasury shares are accounted for under the cost method. Segment , Customer and Geographic Information The Company operates in one ’s core business, which is professional services for government and commercial clients. Although the Company describes its four Approximately $563 $540 $532 2016, 2015, 2014, 48%, 48%, 51% 10% December 31, 2016, 2015, 2014. The Company ’s international operations offer services to both commercial and non-U.S. government customers. Revenue is attributed to location based on the geographic areas to which a contract is awarded. The Company’s revenue generated from international clients as a percentage of total revenue was approximately 10%, 11%, 12% 2016, 2015, 2014. At December 31, 2016 2015, long-lived assets from international offices were not material as compared to the Company’s total long-lived assets. Risks and Uncertainties Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and contract receivables. The majority of the Company ’s cash transactions are processed through one December 31, 2016 2015, $5.4 $6.7 The Company ’s contract receivables consist principally of contract receivables from agencies and departments of, as well as from prime contractors to, the federal government, other governments, and commercial organizations. The Company believes that this credit risk with respect to contract receivables, is limited due to the credit worthiness of the U.S. government. Contract receivable credit risk is also limited due to a large number of customers in differing agencies of the U.S. government. The Company extends credit in the normal course of operations and does not require collateral from its clients. The Company has historically been, and continues to be, heavily dependent upon contracts with the federal government and is subject to audit by agencies of the federal government. Such audits determine, among other things, whether an adjustment of invoices rendered to the government is appropriate under the underlying terms of the contracts. Management does not expect any significant adjustments as a result of government audits that will adversely affect the Company’s financial position. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

The need to establish valuation allowances for deferred assets is based on a more-likely-than-not threshold that the benefit of such assets will be realized in future periods. Appropriate consideration has been given to all available evidence, including historical operating results, projections of taxable income, and tax planning alternatives. The Company concluded that a valuation allowance of approximately $1.1 $0.9 December 31, 2016 2015, The net change in the total valuation allowance for 2016 $0.2 2015. $0.2 the Company is winding down operations. This increase is offset partially by the release of a valuation allowance in another foreign jurisdiction where the Company has ongoing operations to reflect the benefit realized from the utilization of net operating loss and other deduction carryforwards related to the reorganization of a business unit in that jurisdiction. T he Company made no provisions for deferred U.S. income taxes or additional foreign taxes on any unremitted earnings of its controlled foreign subsidiaries because the Company considers these earnings to be permanently invested. If these earnings were repatriated, in the form of dividends or otherwise, the Company would be subject to U.S. income tax on these earnings. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable due to the complexities associated with this hypothetical calculation; however, unrecognized foreign tax credit carry forwards would be available to reduce some portion of the related U.S. tax liability. The Company has $2.6 December 31, 2016.

The Company had approximately $0.2 $0.1 December 31, 2016, 2015, The Company ’s 2013 2016 2012 2016. Although the Company believes it has adequately provided for all uncertain tax positions, amounts asserted by taxing authorities could be greater than the Company ’s accrued position. Accordingly, additional provisions on federal, state and foreign income tax related matters could be recorded in the future as revised estimates are made or the underlying matters are effectively settled or otherwise resolved. Conversely, the Company could settle positions with the tax authorities for amounts lower than have been accrued.

Earnings Per Share [Text Block]	NOTE 14 —EARNINGS PER SHARE Earnings Per Share EPS is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted EPS considers the potential dilution that could occur if common stock equivalents were exercised or converted into stock. The difference between the basic and diluted weighted-average equivalent shares with respect to the Company ’s EPS calculation is due entirely to the assumed exercise of stock options and the vesting and settlement of RSUs. PSAs are included in the computation of diluted shares only to the extent that the underlying performance conditions (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end of the reporting period were the end of the related performance period and the result would be dilutive under the treasury stock method.

Significant Accounting Policies

Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The Company recognizes revenue when persuasive evidence of an arrangement exists, services have been rendered, the contract price is fixed or determinable, and collectability is reasonably assured. The Company enters into three • Time-and-Materials Contracts. Revenue for time-and-materials contracts is recorded on the basis of allowable labor hours worked multiplied by the contract-defined billing rates, plus the costs of other items used in the performance of the contract. Profits and losses on time-and-materials contracts result from the difference between the cost of services performed and the contract-defined billing rates for these services. • Cost-Based Contracts . • Fixed-Price Contracts . may one • Proportional Performance: Revenue on certain fixed-price contracts is recognized based on proportional performance when the provision of services extends beyond an accounting period with more than one progress towards completion can be measured based on a reliable output or input. Under this method, revenue is recorded each period based upon certain contract performance input measures incurred (labor hours, labor costs, or total costs) or output measures completed, expressed as a proportion of a total project estimate. Progress on a contract is monitored regularly to ensure that revenue recognized reflects project status. When hours or costs incurred are used as the basis for revenue recognition, the hours or costs incurred represent a reasonable surrogate for output measures of contract performance, including the presentation of deliverables to the client. Clients are obligated to pay as services are performed, and in the event that a client cancels the contract, payment for services performed through the date of cancellation is typically negotiated with the client. • Specific Performance : hen the services to be performed consist of a single act, revenue is recognized at the time the act is performed or at the completion of the single service. • Straight-Line : When services are performed or are expected to be performed consistently throughout an arrangement, or when the Company is compensated on a retainer or fixed-fee basis, revenue is recognized ratably over the period benefited. • Completed Contract : Revenue and costs on certain fixed-price contracts are recognized at completion if the final act is so significant to the arrangement that value is deemed to be transferred only at completion. Revenue recognition requires the Company to use judgment relative to assessing risks, estimating contract revenue and costs or other variables, and making assumptions for scheduling and technical issues. Due to the size and nature of many of the Company’s contracts, the estimation of revenue and estimates at completion can be complicated and are subject to many variables. Contract costs include labor, subcontractor costs, and other direct costs, as well as an allocation of indirect costs. At times, the Company must also make assumptions regarding the length of time to complete the contract because costs include expected increases in wages, prices for subcontractors, and other direct costs. From time to time, facts develop that require the Company to revise its estimated total costs or hours and thus the associated revenue on a contract. To the extent that a revised estimate affects contract profit or revenue previously recognized, the Company records the cumulative effect of the revision in the period in which the facts requiring the revision become known. A provision for the full amount of an anticipated loss on any type of contract is recognized in the period in which it becomes probable and can be reasonably estimated. As a result, operating results could be affected by revisions to prior accounting estimates. C ontractual arrangements are evaluated to assess whether revenue should be recognized on a gross versus net basis. Management’s assessment when determining gross versus net revenue recognition is based on several factors, such as whether the Company serves as the primary service provider, has autonomy in selecting subcontractors, or has credit risk, all of which are primary indicators that the Company serves as the principal to the transaction. In such cases, revenue is recognized on a gross basis. When such indicators are not present and the Company is primarily functioning as an agent under an arrangement, revenue is recognized on a net basis. Payments to the Company on cost-based contracts with the federal government are provisional payments subject to adjustment upon audit by the government. Such audits have been finalized through December 31, 2007, The Company generates invoices to clients in accordance with the terms of the applicable contract, which may the Company included in the cost of revenue. The Company records revenue net of taxes collected from customers to be remitted to governmental authorities. The Company may documents. It has a review process for approving any such work. Revenue associated with such work is recognized only when it can be reliably estimated and realization is probable. The Company bases its estimates on a variety of factors, including previous experiences with the client, communications with the client regarding funding status, and its knowledge of available funding for the contract.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers cash on deposit and all highly liquid investments with original maturities of three when purchased to be cash and cash equivalents.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash The Company has restricted cash representing amounts held in escrow accounts and/or not readily available due to contractual restrictions.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Allowance for Doubtful Accounts The Company considers a number of factors in its estimate of allowance for doubtful accounts, including the customer ’s financial condition, historical collection experience, and other factors that may
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are carried at cost and are depreciated using the straight-line method over their estimated useful lives, which range from two seven
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and Other Intangible Assets The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired , less liabilities assumed, based upon their respective fair values, with the excess recorded as goodwill. Goodwill represents the excess of costs over the fair value of net assets of businesses acquired. Goodwill and intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead are reviewed for impairment annually, or more frequently if impairment indicators arise. Intangible assets with estimable useful lives are amortized over such lives and reviewed for impairment if impairment indicators arise.
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Impairment The Company performs its annual goodwill impairment review as of September 30 one September 30, 2016, may two The Company ’s qualitative analysis as of September 30, 2016, one two 2016. no September 30, 2016. no The Company is required to review long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less cost to sell.
Research, Development, and Computer Software, Policy [Policy Text Block]	Capitalized Software The Company capitalizes eligible costs to develop enhancements and upgrades to internal-use software that are incurred subsequent to the preliminary project stage. Amortization expense is recorded on a straight-line basis over the expected economic life, typically three five December 31, 2016, 2015, 2014,
Deferred Charges, Policy [Policy Text Block]	Deferred Rent The Company recognizes rent expense on a straight-line basis over the non-cancellable term of each lease, including renewal option periods when renewal is reasonably assured or executed. Lease incentives or abatements received at or near the inception of leases are accrued and amortized ratably over the life of the lease.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-based Compensation The Company recognizes stock-based compensation expense related to share-based payments to employees, including grants of employee stock options, restricted stock awards, restricted stock units (“RSUs”) , and cash-settled restricted stock units (“CSRSUs”) on a straight-line basis over the requisite service period, which is generally the vesting period. The Company recognizes expense for performance-based share awards (“PSAs”), which have a performance condition and a market condition, on a straight-line basis over the performance period. Non-employee director awards do not include vesting conditions and therefore are expensed when issued. Stock-based c ompensation expense is based on the estimated fair value of these instruments and the estimated number of shares the Company ultimately expects will vest. The Company estimates the rate of future forfeitures based on factors such as historical experience and employee class. In addition, the estimation of PSAs that will ultimately vest requires judgment based on performance conditions. Changes to these estimates are recorded as a cumulative adjustment in the period estimates are revised. The fair value of stock options, restricted stock awards, RSUs , PSAs, and non-employee director awards is estimated based on the fair value of a share of common stock at the grant date. The Company has elected to use the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The fair value of PSAs is estimated using a Monte Carlo simulation model. CSRSUs are settled only in cash payments. The cash payment is based on the fair value of the Company ’s stock price at the vesting date, calculated by multiplying the number of CSRSUs vested by the Company’s closing stock price on the vesting date, subject to a maximum payment cap and a minimum payment floor. The Company treats these awards as liability-classified awards, and therefore accounts for them at fair value estimated based on the closing price of the Company’s stock at the reporting date.
Comprehensive Income, Policy [Policy Text Block]	Other Comprehensive (Loss) Income Other comprehensive (loss) income represents foreign currency translation adjustments arising from the use of differing exchange rates from period to period and the gain on the sale of an interest rate hedge agreement. The financial positions and results of operations of the Company’s foreign subsidiaries are based on the local currency as the functional currency and are translated to U.S. dollars for financial reporting purposes. Assets and liabilities of the subsidiaries are translated at the exchange rate in effect at each period-end. Income statement accounts are translated at the average rate of exchange prevailing during the period. Translation adjustments are included in accumulated other comprehensive (loss) income in stockholders’ equity in the Company’s consolidated balance sheets. The activity included in other comprehensive (loss) income in the Company’s consolidated statements of comprehensive income for each period reported is summarized below.

Income Tax, Policy [Policy Text Block]	Income Taxe s The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The Company evaluates its ability to benefit from all deferred tax assets and establishes valuation allowances for amounts it believes are not more likely than not to be realizable. For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the income tax position taken. Income tax positions that meet the more-likely-than-not recognition threshold are measured in order to determine the tax benefit recognized in the financial statements. Penalties, if probable and reasonably estimable, and interest expense related to uncertain tax positions are not recognized as a component of income tax expense but recorded separately in indirect expenses.
Derivatives, Methods of Accounting, Hedging Derivatives [Policy Text Block]	Derivative Instruments Derivative instruments designated as cash flow hedges are recorded on the consolidated balance sheet at fair value , at the reporting date, and the effective portion of the hedge is recorded in other comprehensive (loss) income on the consolidated statement of comprehensive income and reclassified to earnings in the period that the hedged instruments affect earnings.
