Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Basis of Presentation and Consolidation These condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to the SEC rules and regulations. There are no unconsolidated entities, or off-balance sheet arrangements other than certain guarantees supporting office leases and the performance under government contracts in the Company's European operations. All inter-company accounts have been eliminated. The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires the Company's management to make estimates, judgments and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, the valuation allowance for deferred tax assets, actuarial assumptions including discount rates and expected rates of return on assets, as applicable, for the Company's defined benefit plans, the allowance for doubtful accounts receivable, assumptions underlying stock option valuation, investment valuation, legal matters, other contingencies, and progress toward completion and direct profit or loss on contracts. Management believes that the information and disclosures provided herein are adequate to present fairly the condensed consolidated financial position, results of operations, comprehensive income (loss), cash flows, and shareholders’ equity of the Company. The Company evaluated subsequent events from the date of the most recent balance sheet through the date of this filing. There are no subsequent events that require recognition or disclosure in these unaudited interim condensed consolidated financial statements. The Company operates in one industry, providing IT services to its clients. At the highest level, CTG delivers services that are considered either IT solutions or IT and other staffing. CTG provides these primary services to all of the markets that it serves. The services provided typically encompass the IT business solution life cycle, including phases for planning, developing, implementing, managing, and ultimately maintaining the IT solution. A typical customer is an organization with large, complex information and data processing requirements. IT solutions and IT and other staffing revenue as a percentage of total revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 IT solutions 35.5 % 31.6 % 34.9 % 31.0 % IT and other staffing 64.5 % 68.4 % 65.1 % 69.0 % Total 100.0 % 100.0 % 100.0 % 100.0 % The Company promotes a significant portion of its services through five vertical market focus areas: technology service providers, manufacturing, healthcare (which includes services provided to healthcare providers, health insurers (payers), and life sciences companies), financial services, and energy. The Company focuses on these five vertical areas as it believes that these areas are either higher growth markets than the general IT services market and the general economy, or are areas that provide greater potential for the Company’s growth due to the size of the vertical market. The remainder of CTG’s revenue is derived from general markets. CTG’s revenue by vertical market as a percentage of total revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Technology service providers 31.7 % 32.6 % 32.1 % 32.7 % Manufacturing 17.1 % 18.4 % 17.1 % 18.9 % Healthcare 16.7 % 15.9 % 16.5 % 15.6 % Financial services 13.4 % 15.7 % 13.7 % 15.1 % Energy 5.5 % 5.0 % 5.1 % 4.9 % General markets 15.6 % 12.4 % 15.5 % 12.8 % Total 100.0 % 100.0 % 100.0 % 100.0 % Revenue Recognition The Company recognizes revenue when control of the promised good or service is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. For time-and-material contracts, revenue is recognized as hours are incurred and costs are expended. For contracts with progress billing schedules (i.e. progress billing), primarily monthly, revenue is recognized as services are rendered to the customer. Revenue for fixed-price contracts is recognized over time using an input-based approach. Recognizing revenue over time best portrays the Company’s performance in transferring control of the goods or services to the customer. On most fixed price contracts, revenue recognition is supported through contractual clauses that require the customer to pay for work performed to date, including cost plus a reasonable profit margin, for goods or services that have no alternative use to the Company. On certain contracts, revenue recognition is supported through contractual clauses that indicate the customer controls the asset, or work in process, as the Company creates or enhances the asset. On a given project, actual salary and indirect labor costs incurred are measured and compared with the total estimate of costs of such items at the completion of the project. Revenue is recognized based upon the percentage-of-completion calculation of total incurred costs to total estimated costs. The Company infrequently works on fixed-price projects that include significant amounts of material or other non-labor related costs that could distort the percent complete within a percentage-of-completion calculation. The Company’s estimate of the total labor costs it expects to incur over the term of the contract is based on the nature of the project and experience on similar projects, and includes management judgments and estimates that affect the amount of revenue recognized on fixed-price contracts in any accounting period. Losses on fixed-price projects are recorded when identified. The Company’s revenue from contracts accounted for under time-and-material, progress billing and percentage-of-completion methods as a percentage of consolidated revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Time-and-material 79.3 % 87.7 % 79.7 % 87.1 % Progress billing 10.4 % 9.8 % 10.6 % 9.9 % Percentage-of-completion 10.3 % 2.5 % 9.7 % 3.0 % Total 100.0 % 100.0 % 100.0 % 100.0 % The Company recorded revenue in the quarter and two quarters ended June 28, 2019 and June 29, 2018 as follows: For the Quarter Ended: June 28, 2019 June 29, 2018 Year-over-Year Change (amounts in thousands) North America 62.4 % $ 62,653 65.3 % $ 60,522 3.5 % Europe 37.6 % 37,755 34.7 % 32,145 17.5 % Total 100.0 % $ 100,408 100.0 % $ 92,667 8.4 % For the Two Quarters Ended: June 28, 2019 June 29, 2018 Year-over-Year Change (amounts in thousands) North America 61.8 % $ 122,088 65.1 % $ 114,214 6.9 % Europe 38.2 % 75,558 34.9 % 61,166 23.5 % Total 100.0 % $ 197,646 100.0 % $ 175,380 12.7 % Significant Judgments With the exception of cost estimates on certain fixed-price projects, there are no other significant judgments used to determine the timing of the satisfaction of performance obligations or determining the transaction price and amounts allocated to performance obligations. The Company allocates the transaction price based on standalone selling prices for contracts with customers that include more than one performance obligation. We determine standalone selling price based on the expected cost of the good or service plus margin approach. Certain customers may qualify for discounts and rebates, which we account for as variable consideration. We estimate variable consideration and reduce revenue recognized based on the amount we expect to provide to customers. Contract Balances For time-and-material contracts and contracts with periodic billing schedules, the timing of the Company’s satisfaction of its performance obligations is consistent with the timing of payment. For these contracts, the Company has the right to payment in the amount that corresponds directly with the value of the Company’s performance to date. The Company uses the practical expedient that allows the Company to recognize revenue in the amount for which it has the right to invoice for time-and-material contracts and contracts with periodic billing schedules. Bill schedules for fixed-price contracts are generally consistent with the Company’s performance in transferring control of the goods or services to the customer. There are no significant financing components in contracts with customers. The Company records advanced billings that represent contract liabilities for cash payments received in advance of performance on the condensed consolidated balance sheet. Unbilled receivables are reported within “accounts receivable” on the condensed consolidated balance sheet. Accounts receivable and advanced billings balances fluctuate based on the timing of the customer’s billing schedule and the Company’s month-end date. There are no significant costs to obtain or fulfill contracts with customers. Transaction Price Allocated to Remaining Performance Obligations As of June 28, 2019, the aggregate transaction price allocated to unsatisfied or partially unsatisfied performance obligations for fixed-price and all managed-support contracts was approximately $12.3 million and $46.0 million, respectively. Approximately $26.1 million of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations is expected to be earned in 2019. Approximately $32.2 million of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations is expected to be earned in 2020 and beyond. As the Company uses the “right to invoice” practical expedient, we do not disclose the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. Taxes Collected from Customers In instances where the Company collects taxes from its customers for remittance to governmental authorities, primarily in its international locations, revenue and expenses are not presented on a gross basis in the condensed consolidated financial statements as such taxes are recorded in the Company's accounts on a net basis. Fair Value Fair value is defined as the exchange price that would be received for an asset or paid for a liability in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants. The Company utilizes a fair value hierarchy for its assets and liabilities, as applicable, based upon three levels of input, which are: Level 1—quoted prices in active markets for identical assets or liabilities (observable) Level 2—inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in inactive markets, or other inputs that are observable or can be supported by observable market data for essentially the full term of the asset or liability (observable) Level 3—unobservable inputs that are supported by little or no market activity, but are significant to determining the fair value of the asset or liability (unobservable) At June 28, 2019 and December 31, 2018, the carrying amounts of the Company’s cash of $11.3 million and $12.4 million, respectively, approximated fair value. As described in Note 3 of the condensed consolidated financial statements, the Company acquired 100% of the equity of Soft Company in the 2018 first quarter. Level 3 inputs were used to estimate the fair values of the assets acquired and liabilities assumed. The valuation techniques used to assign fair values to intangible assets included the relief-from-royalty method and excess earnings method. In addition, the Company has a contingent consideration liability related to the earn-out provision of which a portion will be payable in each period subject to the achievement by Soft Company of certain revenue and EBIT targets for fiscal 2017, 2018, and 2019. There is no payout if the achievement on either target is below a certain target threshold. The fair value of this contingent consideration is determined using level 3 inputs. The fair value assigned to the contingent consideration liability is determined using the real options method, which requires inputs such as revenue forecasts, EBIT forecasts, discount rate, and other market variables to assess the probability of Soft Company achieving the revenue and EBIT targets. The Company also acquired Tech-IT in the 2019 first quarter, and the Company anticipates completing the accounting for the acquisition in the 2019 third quarter. The Company is also allowed to elect an irrevocable option to measure, on a contract-by-contract basis, specific financial instruments and certain other items that are currently not being measured at fair value. The Company did not elect to apply the fair value provisions of this accounting standard for any specific contracts during the quarters ended June 28, 2019 or June 29, 2018. Life Insurance Policies The Company has purchased life insurance on the lives of a number of former employees who are plan participants in the non-qualified defined benefit Executive Supplemental Benefit Plan. In total, there are policies on 18 individuals, whose average age is 75 years old. Those policies have generated cash surrender value and the Company has taken loans against the policies. At June 28, 2019, these insurance policies have a gross cash surrender value of $28.8 million, outstanding loans and interest totaling $26.4 million, and a net cash surrender value of $2.4 million. At December 31, 2018, these insurance policies had a cash surrender value of $28.4 million, outstanding loans and interest totaling $25.8 million, and a net cash surrender value of $2.6 million. The net cash surrender values are included on the condensed consolidated balance sheet in “Cash surrender value of life insurance” under non-current assets. At both June 28, 2019 and December 31, 2018, the total death benefit for the remaining policies was approximately $37.6 million. Currently, upon the death of all of the remaining plan participants, the Company would expect to receive approximately $10.9 million after the payment of obligations, and, under current tax regulations, record a non-taxable gain of approximately $8.5 million. Cash and Cash Equivalents, and Cash Overdrafts For purposes of the statement of cash flows, cash and cash equivalents are defined as cash on hand, demand deposits, and short-term, highly liquid investments with an original maturity of three months or less. As the Company does not fund its bank accounts for the checks it has written until the checks are presented to the bank for payment, the "change in cash overdraft, net," line item as presented on the condensed consolidated statements of cash flows represents the increase or decrease in outstanding checks in a given period. Property, Equipment and Capitalized Software Costs Property, equipment and capitalized software at June 28, 2019 and December 31, 2018 are summarized as follows: (amounts in thousands) June 28, 2019 December 31, 2018 Property, equipment and capitalized software $ 18,721 $ 18,292 Accumulated depreciation and amortization (13,280 ) (12,636 ) Property, equipment and capitalized software, net $ 5,441 $ 5,656 The Company recorded less than $0.1 million of capitalized software costs during both the quarter and two quarters ended June 28, 2019 and June 29, 2018, respectively. As of those dates, the Company had capitalized a total of $2.0 Guarantees The Company has a number of guarantees in place in its European operations that support office leases and performance under government contracts. At both Goodwill The goodwill recorded on the Company's condensed consolidated balance sheet at June 28, 2019 relates to the acquisition of Soft Company in the 2018 first quarter, and Tech-IT in the 2019 first quarter. In accordance with current accounting guidance for “Intangibles - Goodwill and Other,” the Company performs goodwill impairment testing at least annually (in the Company’s fourth quarter), unless indicators of impairment exist in interim periods. The changes in the carrying amount of goodwill for the two quarters ended June 28, 2019 are as follows: (amounts in thousands) Balance at December 31, 2018 $ 11,664 Acquired goodwill 7,814 Foreign currency translation 10 Balance at June 28, 2019 $ 19,488 Acquired Intangible Assets Acquired intangible assets at June 28, 2019 consist of the following: (amounts in thousands) Estimated Economic Life Gross Carrying Amount Accumulated Amortization Foreign Currency Translation Net Carrying Amount Trademarks 2 year $ 749 $ 469 $ (67 ) $ 213 Customer relationships 13 years 6,489 626 (574 ) 5,289 Total $ 7,238 $ 1,095 $ (641 ) $ 5,502 Estimated amortization expense for the remainder of 2019, the five succeeding years, and thereafter is as follows: Year Annual Amortization (amounts in thousands) 2019 $ 398 2020 498 2021 455 2022 455 2023 455 2024 455 Thereafter 2,786 Total $ 5,502 Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). On January 1, 2019, the Company adopted the new lease standard using the modified retrospective transition approach and elected the transition method to apply the new lease standard as of the January 1, 2019 adoption date. Results for the reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts are not adjusted and continue to be reported in accordance with accounting under Topic 840. In addition, the Company elected the ‘package of practical expedients’, which permits the Company not to reassess under the new standard prior conclusions about lease identification, lease classification, and initial direct costs. The Company has also elected the practical expedient to separate lease and non-lease components for its office leases and has elected to group lease and non-lease components for its vehicle leases. Upon adoption of Topic 842 on January 1, 2019, the Company recorded approximately $13.1 million of operating lease right-of-use assets and In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments”, which requires the immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including trade receivables. This guidance is effective for reporting periods beginning after December 15, 2019; however, early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-13 will have on its condensed consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	3. Tech-IT PSF S.A. (“Tech-IT”) On February 6, 2019, the Company acquired 100% of the equity of Tech-IT for approximately $9.7 million. The acquisition was funded using cash on hand and borrowings under the Credit and Security Agreement. Tech-IT, located in Bertrange, Luxembourg, is a leading provider of software and hardware services, including consulting, infrastructure and software design and development, infrastructure integration, project management, and training. The acquisition of Tech-IT is expected to enable the Company to strengthen its market position in Luxembourg and broaden its portfolio to offer complete end-to-end IT solutions. An earn-out of up to a maximum of $1.7 million (€1.5 million based on a EUR into USD exchange rate of 1.1225) can be earned, a portion of which will be payable in each period subject to the achievement of direct profit targets for fiscal 2018, 2019, and 2020. There is no payout if the achievement is below the target threshold. The results of operations of Tech-IT have been included in the Company’s consolidated financial results since the date of acquisition. As the Company has determined that the acquisition is not material to its existing operations, certain disclosures, including pro forma financial information, have not been included in this quarterly report on Form 10-Q. As of the date of filing this quarterly report on Form 10-Q, the preliminary purchase accounting has not yet been finalized due primarily to the timing of information being provided to our valuation specialist and the pending receipt of a preliminary valuation report for certain assets and liabilities, including identified intangible assets. The Company expects to update this information in the third quarter. At June 28, 2019, the Company allocated value to current assets and liabilities based on book values at February 6, 2019, which approximates fair value. The remaining purchase price is preliminarily allocated to goodwill. Soft Company SAS (“Soft Company”) On February 15, 2018, the Company acquired 100% of the equity of Soft Company for approximately $16.9 million (€13.6 million based on a EUR into USD exchange rate of 1.2392). The acquisition was funded using cash on hand and borrowings under the Company’s Credit and Security Agreement. Soft Company, located in Paris, France, is an IT consulting company that specializes in providing IT services to finance, insurance, telecom, and media services companies. The acquisition of Soft Company is expected to enable the Company to expand its position in Europe and enhance its service offerings. The Company has a contingent consideration liability related to an earn-out provision of which a portion will be payable in each period subject to the achievement by Soft Company of certain revenue and EBIT targets for fiscal 2017, 2018, and 2019. There is no payout if the achievement on either target is below a certain target threshold. The fair value as of the February 15, 2018 acquisition date was determined to be $2.0 million. In the 2018 second quarter, the Company paid approximately $0.9 million relating to the earn-out based on the achievement by Soft Company of certain revenue and EBIT targets for fiscal 2017. The fair value of the remaining contingent consideration liability was determined to be approximately $1.9 million as of June 28, 2019. As such, the Company recorded $0.5 million of selling, general and administrative expense during the first two quarters of 2019. The remaining contingent consideration liability is recorded in “other current liabilities” on the June 28, 2019 condensed consolidated balance sheet. The acquisition date fair value of the consideration for the acquisition of Soft Company consisted of the following as of February 15, 2018: (amounts in thousands) Cash consideration $ 16,910 Fair value of contingent consideration 1,997 Fair value of purchase consideration $ 18,907 The following table summarizes the allocation of the aggregate purchase consideration to the fair value of the assets acquired and liabilities assumed as of February 15, 2018: (amounts in thousands) Assets Acquired: Cash $ 4,059 Accounts receivable 5,551 Prepaids & other 243 Property & equipment 53 Acquired intangibles 7,238 Goodwill 12,720 Total assets acquired $ 29,864 Liabilities Assumed: Accounts payable 4,085 Accrued compensation 2,669 Other short-term liabilities 2,006 Deferred income taxes 1,827 Other long-term liabilities 370 Total liabilities assumed $ 10,957 Net assets acquired $ 18,907 The purchase consideration for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill, which is not deductible for income tax purposes. The intangible assets acquired in this acquisition consisted of the following: (amounts in thousands) Fair Value Estimated Useful Life Trademarks $ 749 2 years Customer relationships 6,489 13 years Fair value of purchase consideration $ 7,238 The results of operations of Soft Company have been included in the Company’s consolidated financial results since the date of acquisition. As the Company has determined that the acquisition is not material to its existing operations, certain disclosures, including pro forma financial information, have not been included in this quarterly report on Form 10-Q. The Company incurred acquisition-related legal and consulting fees, adjustments to the fair value of the earn-out liability, and amortization of intangible assets of approximately $0.5 million and $0.9 million in the 2019 second quarter and year-to-date period, respectively, which were recorded as a component of selling, general, and administrative expenses in the condensed consolidated statements of income. The purchase price allocation for this acquisition has been finalized.

Leases [Abstract]
Operating Leases	5. Operating Leases The Company is obligated under a number of long-term operating leases for office space, office equipment, and automobiles leased in Europe. On January 1, 2019, the Company adopted Topic 842 using the modified retrospective transition approach and elected the transition method to apply the new lease standard as of the January 1, 2019 adoption date. Results for the reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 840. Most leases contain both lease components (fixed payments for rent) and non-lease components (common-area maintenance and other services). The Company has elected the practical expedient to separate lease and non-lease components for its office leases and has elected to group lease and non-lease components for its vehicle leases. Some leases contain renewal options with escalation clauses commensurate with local market fluctuations, however, generally limiting an annual increase to no more than 5.0% of the existing lease payment. The exercise of lease renewal options is at the Company’s sole discretion. The Company has excluded renewal options in the measurement of right-of-use assets and lease liabilities if they are not reasonably certain of exercise. Operating leases are included in the right-of-use lease assets, short-term lease liabilities, and long-term lease liabilities on the condensed consolidated balance sheet. The Company measures the operating lease liabilities at lease commencement date based on the present value of remaining lease payments using the rate implicit in the lease when readily determinable, or the Company’s secured incremental borrowing rates. The Company has made an accounting policy election not to recognize a lease liability or right-of-use asset for leases with a lease term of twelve months or less and does not include an option to purchase the underlying asset. The Company recognizes lease expense on a straight-line basis over the lease term and variable lease expense in the period incurred. Variable lease cost consists primarily of common-area maintenance, insurance, and taxes, which are paid based on actual costs incurred by the lessor. Operating lease cost for the 2019 second quarter and year-to-date period was $1.7 million and $3.4 million, respectively. Operating lease expense in the 2018 second quarter and year-to-date period was $1.5 million and $3.0 million, respectively. The Company incurred variable lease cost of $0.2 million and $0.3 million, and short-term lease cost of $0.1 million and $0.3 million in the 2019 second quarter and year-to-date period, respectively. Maturities for the Company’s lease liabilities for all operating leases as of June 28, 2019 are as follows: Total Year Operating Leases (amounts in thousands) 2019 (remaining) $ 2,870 2020 4,838 2021 3,537 2022 2,185 2023 1,404 2024 & thereafter 332 Total undiscounted operating lease payments $ 15,166 Less: Interest (690 ) Total present value of operating lease liabilities $ 14,476 Operating lease payments exclude $5.1 million of legally binding lease payments for leases signed, but not yet commenced. The weighted average remaining lease term and discount rate for all operating leases as of June 28, 2019 are as follows: June 28, 2019 Weighted average remaining lease term (years) 3.43 Weighted average remaining discount rate 2.84 % An initial right-of-use asset of $13.1 million was recognized as a non-cash asset addition upon adoption of Topic 842. Supplemental cash flow information related to the Company’s operating leases for the first two quarters of 2019 is as follows: (amounts in thousands) June 28, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash outflow from operating leases $ 3,382 Right-of-use assets obtained in exchange for new operating lease liabilities 4,308 As of December 31, 2018, minimum obligations under operating leases were as follows: Total Year Operating Leases (amounts in thousands) 2019 $ 5,586 2020 4,420 2021 3,050 2022 2,166 2023 1,411 2024 & thereafter 1,192 Minimum future lease obligations $ 17,825

Debt Disclosure [Abstract]
Debt	6. Debt The Company has a credit and security agreement (the “Credit and Security Agreement”) with its bank, which provides for a three-year revolving credit facility in an aggregate principal amount of $45.0 million, including a sublimit of $10.0 million for letters of credit and a $10.0 million sublimit for swing line loans. The Credit and Security Agreement expires in December 2020, and has interest rates ranging from 150 to 200 basis points over LIBOR or the greater of (i) the prime rate, (ii) the federal fund effective rate plus 50 basis points, and (iii) adjusted LIBOR plus 100 basis points plus a spread ranging from 50 to 100 basis points based on the amounts outstanding under the Credit and Security Agreement. The Company can borrow under the agreement with either rate at its discretion. At June 28, 2019 and June 29 , 2018 , there was $ 17.0 million and $ 6.3 million outstanding under the Credit and Security Agreement, respectively. The Company borrows or repays its debt as needed based upon its working capital obligations, including the timing of the U.S. bi-weekly payroll. The maximum amounts outstanding under its credit agreement in the 2019 and 2018 second quarters were $22.3 million and $10.4 million, respectively, while borrowings during those quarters averaged $15.1 million and $3.5 million, respectively, and carried weighted average interest rates of 3.2% and 3.3%, respectively. Under the Credit and Security Agreement, the Company is required to meet certain financial covenants in order to maintain borrowings under its revolving credit line, pay dividends, and make acquisitions. The covenants are measured quarterly, and at June 28, 2019, included a fixed charge coverage ratio, which must be less than 1.10 to 1.00, consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) adjusted for equity-based compensation and severance expenses, must be no less than $5.0 million for the trailing twelve months, and capital expenditures for property, plant, equipment, and capitalized software must be no more than $5.0 million in any annual period. The fixed charge coverage ratio is only tested if availability on a measurement date is less than $5.625 million. Actual borrowings by CTG under the Credit and Security Agreement are subject to a borrowing base, which is a formula based on certain eligible receivables and reserves. Total availability as of June 28, 2019 was approximately $22.6 million. The Company was in compliance with these covenants at June 28, 2019 as adjusted EBITDA for the trailing twelve months was $8.6 million and capital expenditures for property, equipment and capitalized software were $0.7 million in the first two quarters of 2019. The Company was also in compliance with its covenants at June 29, 2018.

Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The Company’s effective tax rate (“ETR”) is calculated quarterly based upon current assumptions relating to the full year’s estimated operating results and various tax-related items. The 2019 second quarter and year-to-date ETR was 36.6% and 35.3%, respectively, and the 2018 second quarter and year-to-date ETR was 27.8% and 26.1%, respectively. The ETR was higher in the 2019 second quarter and year-to-date period as compared with the corresponding 2018 periods primarily due to non-deductible acquisition costs related to the Tech-IT and Soft Company acquisitions. The Company has not recorded a U.S. deferred tax liability for the excess book basis over the tax basis of its investments in foreign subsidiaries as these amounts continue to be indefinitely reinvested in foreign operations.

Deferred Compensation and Other

Compensation And Retirement Disclosure [Abstract]
Deferred Compensation and Other Benefits	9. Deferred Compensation and Other Benefits The Company maintains a non-qualified defined benefit Executive Supplemental Benefit Plan (ESBP) that provides certain former key executives with deferred compensation benefits, based on years of service and base compensation, payable during retirement. The plan was amended as of November 30, 1994, to freeze benefits for the participants in the plan at that time. The Company retained certain potential obligations related to a contributory defined-benefit plan for its previous employees located in the Netherlands (NDBP) when the Company disposed of its subsidiary, CTG Nederland, B.V. Benefits paid are a function of a percentage of career average pay. This plan was curtailed for additional contributions in January 2003. The Company also maintains a fully funded pension plan related to Belgium employees (BDBP). This is a plan with active employees and the Company expects to make future contributions. As a result of the acquisition of Soft Company on February 15, 2018, the Company maintains an unfunded pension plan related to the current Soft Company employees (FDBP). The Company does not anticipate contributing to the plan in 2019. No benefit payments were made in 2018 and none are expected to be paid in 2019. Net periodic pension cost for the quarters ended June 28, 2019 and June 29, 2018 for the plans is as follows: For the Quarter Ended For the Two Quarters Ended (amounts in thousands) June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Service cost $ 83 $ 89 $ 167 $ 175 Interest cost 146 148 293 296 Expected return on assets (153 ) (162 ) (308 ) (326 ) Amortization of actuarial loss 48 73 96 146 Net periodic pension cost $ 124 $ 148 $ 248 $ 291 The ESBP is deemed to be unfunded as the Company has not specifically identified assets to be used to discharge the deferred compensation benefit liabilities. The Company has purchased insurance on the lives of certain plan participants in amounts deemed to be sufficient to reimburse the Company for the costs associated with the plan for those participants (see note 2 for “Life Insurance Policies”). The Company does not anticipate contributing to the plan other than for benefit payments as required in 2019 and future years. In the 2019 second quarter and year-to-date period, the Company made benefit payments totaling approximately $0.2 million and $0.3 million, respectively, and expects to make payments in 2019 totaling approximately $0.6 million. The Company made benefit payments totaling $0.2 million and $0.3 million in the 2018 second quarter and year-to-date period, respectively. As the NDBP was curtailed for additional contributions in January 2003, no payments were made in the 2019 year-to-date period, and no payments are expected to be made in the remainder of 2019. The Company does not anticipate contributing to the NDBP in 2019. The assets for the NDBP are held by Aegon, a financial services firm located in the Netherlands. The Company maintains a contract with Aegon to insure future benefit payments of the NDBP; however, due to certain terms of the agreement and potential obligations to the Company, the NDBP has not been settled. The benefit payments to be made in 2019 are expected to be paid by Aegon from plan assets. The assets for the plan are included in a general portfolio of government bonds, a portion of which is allocated to the NDBP based upon the estimated pension liability associated with the plan. The fair market value of the plan’s assets equals the contractual value of the NDBP at any point in time. The fair value of the assets is determined using a Level 3 methodology (see note 2 for “Fair Value”). In 2019, the plan investments have a targeted minimum return to the Company of 4.0%, which is consistent with historical returns and the 4.0% return guaranteed to the participants of the plan. The Company, in conjunction with Aegon, intends to maintain the current investment strategy of investing plan assets solely in government bonds throughout 2019. The BDBP is considered fully funded. The Company made contributions of $0.1 million and $0.2 million in the 2019 second quarter and year-to-date period, respectively, and $0.1 million and $0.2 million in the 2018 second quarter and year-to-date period, respectively. The Company made benefit payments totaling less than $0.1 million in both the 2019 and 2018 second quarters and expects to make payments in 2019 of less than $0.1 million. The assets for the BDBP are held by Allianz, a financial services firm located in Belgium. The Company maintains a contract with Allianz to insure future benefit payments of the BDBP. Contributions made by the Company to Allianz are based on employees’ current salaries. The benefit payments to be made in 2019 are expected to be paid by Allianz from plan assets. The assets for the plan are included in the overall portfolio of assets held by Allianz. The fair market value of the plan’s assets equals the contractual value of the BDBP in any given year (which is the mathematical reserve held by Allianz). The fair value of the assets is determined using a Level 3 methodology (see note 2 “Fair Value”). Allianz does not guarantee a minimum return on the plan investments, whereas Belgian law sets a minimum return to be guaranteed to the participants of the plan. The change in the fair value of plan assets for the plans for the quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Two Quarters Ended (amounts in thousands) June 28, 2019 June 29, 2018 Fair value of plan assets at beginning of period $ 17,403 $ 17,575 Return on plan assets 308 323 Contributions 554 593 Benefits paid (408 ) (435 ) Effect of exchange rate changes (101 ) (502 ) Fair value of plan assets at end of quarter $ 17,756 $ 17,554 The Company maintains the Key Employee Non-Qualified Deferred Compensation Plan for certain key executives. Company contributions to this plan, if any, are based on annually defined financial performance objectives. The Company made no cash contributions in either the 2019 or 2018 second quarters or year-to-date periods for amounts earned in the previous year. Participants in the plan have the ability to purchase stock units from the Company at current market prices using their available investment balances within the plan. In exchange for the cash received, the Company releases shares out of treasury stock equivalent to the number of share units purchased by the participants. These shares of common stock are not entitled to any voting rights, but will receive dividends in the event any are paid. The shares are being held by the Company, and will be released to the participants as prescribed by their payment elections under the plan. There were no stock units purchased in the 2019 or 2018 second quarters . The Company maintains the Non-Employee Director Deferred Compensation Plan for its non-employee directors. There were no cash contributions in either the 2019 or 2018 second quarters or year-to-date periods. Prior to 2018, at the time the contributions were made, the non-employee directors elected to purchase stock units from the Company at current market prices using their available investment balance within the plan. Consistent with the Key Employee Non-Qualified Deferred Compensation Plan, in return for funds received, the Company released shares out of treasury stock equivalent to the number of share units purchased by the participants. These shares of common stock are not entitled to any voting rights, but will receive dividends in the event any are paid. The shares are being held by the Company, and will be released to the participants as prescribed by their payment elections under the plan.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity-based Compensation	10. Equity-based Compensation During the 2019 second quarter and year-to-date period, the Company granted restricted stock totaling 203,400 and 418,726 shares, respectively, which were funded out of treasury stock. During the 2018 second quarter and year-to-date period, the Company granted restricted stock totaling 214,054 and 475,550 shares, respectively, which were funded out of treasury stock. Director Board fees are paid exclusively in deferred stock units. All of the 215,326 shares granted during 2019 first quarter represented restricted stock units that were granted to Board members. The shares vest in four equal quarterly increments. The Company is expensing these grants ratably during the quarter in which they vest. Grants of similar units to the Board members totaled 118,154 and 159,175 in the 2018 second quarter and year-to-date period. No performance awards were granted during the 2019 first or second quarters. Of the 261,496 shares granted in the 2018 first quarter, 216,600 shares represented performance grants with a market condition that were granted to senior management on March 20, 2018. Under these grant agreements, the Company’s stock price must increase 50% to $12.27 for a 30-day period within a three-year period from the date of grant for 50% of the grants to vest. The Company’s stock price must increase 100% to $16.36 for a 30-day period within a three-year period from the date of grant for the remaining 50% of the grants to vest. For these performance grants, the price on the date of grant was $8.18 per share, the expected volatility was 34.5%, the expected dividend yield is zero, and the risk-free rate of return was 2.47%. Given these assumptions, the tranche of the grants that will vest with a 50 % increase in the stock price have a value using a binomial model of $ 2.30 per share, and a derived service period of 1.26 years . For the tranche of the grants that will vest with a 100 % increase in the stock price, the value of the shares is $ 1.30 per share and have a derived service period of 1.85 years . The Company is expensing these grants over the derived service period as noted for each tranche of a grant. The remaining shares granted in the 2018 or 2019 second quarter or year-to-date periods include shares that primarily vest ratably over four years, beginning one year from the date of grant. A small number of the shares granted vest over a period of three years, with 33% of the grant vesting one year from the date of grant, and another 33% vesting each year thereafter until the grant is fully vested to the employee. The restricted shares granted are considered outstanding, can be voted, and are eligible to receive dividends in the event any are paid. However, the restricted shares do not include a non-forfeitable right for the holder to receive dividends and none will be paid in the event the awards do not vest. Accordingly, only vested shares of outstanding restricted stock are included in the basic earnings per share calculation. The shares and share units were granted from the 2010 Equity Award Plan and the 1991 Restricted Stock plan. No stock options were issued during the 2019 first quarter. A total of 26,500 options were granted during the 2019 second quarter on May 31, 2019. The options have a fair value of $1.26 per share using the Black-Scholes valuation model. The assumptions used to calculate the fair value include the price on the date of grant of $4.20 per option, an expected life of 3.7 years, expected volatility of 36.1%, an expected dividend yield of zero, and a risk free rate of 2.2%. The Company granted 13,100 stock options during the 2018 first quarter on February 20, 2018. The options have a fair value of $1.91 per share using a Black-Scholes valuation model. The assumptions used to calculate that fair value include the price on date of grant of $6.45 per option, an expected life of 3.7 years, expected volatility of 34.9%, an expected dividend yield of zero, and a risk free rate of 2.4%. The options vest ratably over three years, and are being expensed over that period. The options were granted from the 2010 Equity Award Plan.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	These condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to the SEC rules and regulations. There are no unconsolidated entities, or off-balance sheet arrangements other than certain guarantees supporting office leases and the performance under government contracts in the Company's European operations. All inter-company accounts have been eliminated. The preparation of financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires the Company's management to make estimates, judgments and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, the valuation allowance for deferred tax assets, actuarial assumptions including discount rates and expected rates of return on assets, as applicable, for the Company's defined benefit plans, the allowance for doubtful accounts receivable, assumptions underlying stock option valuation, investment valuation, legal matters, other contingencies, and progress toward completion and direct profit or loss on contracts. Management believes that the information and disclosures provided herein are adequate to present fairly the condensed consolidated financial position, results of operations, comprehensive income (loss), cash flows, and shareholders’ equity of the Company. The Company evaluated subsequent events from the date of the most recent balance sheet through the date of this filing. There are no subsequent events that require recognition or disclosure in these unaudited interim condensed consolidated financial statements.
Concentration Risk, Credit Risk	The Company operates in one industry, providing IT services to its clients. At the highest level, CTG delivers services that are considered either IT solutions or IT and other staffing. CTG provides these primary services to all of the markets that it serves. The services provided typically encompass the IT business solution life cycle, including phases for planning, developing, implementing, managing, and ultimately maintaining the IT solution. A typical customer is an organization with large, complex information and data processing requirements. IT solutions and IT and other staffing revenue as a percentage of total revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 IT solutions 35.5 % 31.6 % 34.9 % 31.0 % IT and other staffing 64.5 % 68.4 % 65.1 % 69.0 % Total 100.0 % 100.0 % 100.0 % 100.0 % The Company promotes a significant portion of its services through five vertical market focus areas: technology service providers, manufacturing, healthcare (which includes services provided to healthcare providers, health insurers (payers), and life sciences companies), financial services, and energy. The Company focuses on these five vertical areas as it believes that these areas are either higher growth markets than the general IT services market and the general economy, or are areas that provide greater potential for the Company’s growth due to the size of the vertical market. The remainder of CTG’s revenue is derived from general markets. CTG’s revenue by vertical market as a percentage of total revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Technology service providers 31.7 % 32.6 % 32.1 % 32.7 % Manufacturing 17.1 % 18.4 % 17.1 % 18.9 % Healthcare 16.7 % 15.9 % 16.5 % 15.6 % Financial services 13.4 % 15.7 % 13.7 % 15.1 % Energy 5.5 % 5.0 % 5.1 % 4.9 % General markets 15.6 % 12.4 % 15.5 % 12.8 % Total 100.0 % 100.0 % 100.0 % 100.0 %
Revenue Recognition	Revenue Recognition The Company recognizes revenue when control of the promised good or service is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. For time-and-material contracts, revenue is recognized as hours are incurred and costs are expended. For contracts with progress billing schedules (i.e. progress billing), primarily monthly, revenue is recognized as services are rendered to the customer. Revenue for fixed-price contracts is recognized over time using an input-based approach. Recognizing revenue over time best portrays the Company’s performance in transferring control of the goods or services to the customer. On most fixed price contracts, revenue recognition is supported through contractual clauses that require the customer to pay for work performed to date, including cost plus a reasonable profit margin, for goods or services that have no alternative use to the Company. On certain contracts, revenue recognition is supported through contractual clauses that indicate the customer controls the asset, or work in process, as the Company creates or enhances the asset. On a given project, actual salary and indirect labor costs incurred are measured and compared with the total estimate of costs of such items at the completion of the project. Revenue is recognized based upon the percentage-of-completion calculation of total incurred costs to total estimated costs. The Company infrequently works on fixed-price projects that include significant amounts of material or other non-labor related costs that could distort the percent complete within a percentage-of-completion calculation. The Company’s estimate of the total labor costs it expects to incur over the term of the contract is based on the nature of the project and experience on similar projects, and includes management judgments and estimates that affect the amount of revenue recognized on fixed-price contracts in any accounting period. Losses on fixed-price projects are recorded when identified. The Company’s revenue from contracts accounted for under time-and-material, progress billing and percentage-of-completion methods as a percentage of consolidated revenue for the quarter and two quarters ended June 28, 2019 and June 29, 2018 was as follows: For the Quarter Ended For the Two Quarters Ended June 28, 2019 June 29, 2018 June 28, 2019 June 29, 2018 Time-and-material 79.3 % 87.7 % 79.7 % 87.1 % Progress billing 10.4 % 9.8 % 10.6 % 9.9 % Percentage-of-completion 10.3 % 2.5 % 9.7 % 3.0 % Total 100.0 % 100.0 % 100.0 % 100.0 % The Company recorded revenue in the quarter and two quarters ended June 28, 2019 and June 29, 2018 as follows: For the Quarter Ended: June 28, 2019 June 29, 2018 Year-over-Year Change (amounts in thousands) North America 62.4 % $ 62,653 65.3 % $ 60,522 3.5 % Europe 37.6 % 37,755 34.7 % 32,145 17.5 % Total 100.0 % $ 100,408 100.0 % $ 92,667 8.4 % For the Two Quarters Ended: June 28, 2019 June 29, 2018 Year-over-Year Change (amounts in thousands) North America 61.8 % $ 122,088 65.1 % $ 114,214 6.9 % Europe 38.2 % 75,558 34.9 % 61,166 23.5 % Total 100.0 % $ 197,646 100.0 % $ 175,380 12.7 %
Significant Judgments	Significant Judgments With the exception of cost estimates on certain fixed-price projects, there are no other significant judgments used to determine the timing of the satisfaction of performance obligations or determining the transaction price and amounts allocated to performance obligations. The Company allocates the transaction price based on standalone selling prices for contracts with customers that include more than one performance obligation. We determine standalone selling price based on the expected cost of the good or service plus margin approach. Certain customers may qualify for discounts and rebates, which we account for as variable consideration. We estimate variable consideration and reduce revenue recognized based on the amount we expect to provide to customers.
Contract Balances	Contract Balances For time-and-material contracts and contracts with periodic billing schedules, the timing of the Company’s satisfaction of its performance obligations is consistent with the timing of payment. For these contracts, the Company has the right to payment in the amount that corresponds directly with the value of the Company’s performance to date. The Company uses the practical expedient that allows the Company to recognize revenue in the amount for which it has the right to invoice for time-and-material contracts and contracts with periodic billing schedules. Bill schedules for fixed-price contracts are generally consistent with the Company’s performance in transferring control of the goods or services to the customer. There are no significant financing components in contracts with customers. The Company records advanced billings that represent contract liabilities for cash payments received in advance of performance on the condensed consolidated balance sheet. Unbilled receivables are reported within “accounts receivable” on the condensed consolidated balance sheet. Accounts receivable and advanced billings balances fluctuate based on the timing of the customer’s billing schedule and the Company’s month-end date. There are no significant costs to obtain or fulfill contracts with customers.
Transaction Price Allocated to Remaining Performance Obligations	Transaction Price Allocated to Remaining Performance Obligations As of June 28, 2019, the aggregate transaction price allocated to unsatisfied or partially unsatisfied performance obligations for fixed-price and all managed-support contracts was approximately $12.3 million and $46.0 million, respectively. Approximately $26.1 million of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations is expected to be earned in 2019. Approximately $32.2 million of the transaction price allocated to unsatisfied or partially unsatisfied performance obligations is expected to be earned in 2020 and beyond. As the Company uses the “right to invoice” practical expedient, we do not disclose the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.
Taxes Collected from Customers	Taxes Collected from Customers In instances where the Company collects taxes from its customers for remittance to governmental authorities, primarily in its international locations, revenue and expenses are not presented on a gross basis in the condensed consolidated financial statements as such taxes are recorded in the Company's accounts on a net basis.
Fair Value	Fair value is defined as the exchange price that would be received for an asset or paid for a liability in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants. The Company utilizes a fair value hierarchy for its assets and liabilities, as applicable, based upon three levels of input, which are: Level 1—quoted prices in active markets for identical assets or liabilities (observable) Level 2—inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in inactive markets, or other inputs that are observable or can be supported by observable market data for essentially the full term of the asset or liability (observable) Level 3—unobservable inputs that are supported by little or no market activity, but are significant to determining the fair value of the asset or liability (unobservable) At June 28, 2019 and December 31, 2018, the carrying amounts of the Company’s cash of $11.3 million and $12.4 million, respectively, approximated fair value. As described in Note 3 of the condensed consolidated financial statements, the Company acquired 100% of the equity of Soft Company in the 2018 first quarter. Level 3 inputs were used to estimate the fair values of the assets acquired and liabilities assumed. The valuation techniques used to assign fair values to intangible assets included the relief-from-royalty method and excess earnings method. In addition, the Company has a contingent consideration liability related to the earn-out provision of which a portion will be payable in each period subject to the achievement by Soft Company of certain revenue and EBIT targets for fiscal 2017, 2018, and 2019. There is no payout if the achievement on either target is below a certain target threshold. The fair value of this contingent consideration is determined using level 3 inputs. The fair value assigned to the contingent consideration liability is determined using the real options method, which requires inputs such as revenue forecasts, EBIT forecasts, discount rate, and other market variables to assess the probability of Soft Company achieving the revenue and EBIT targets. The Company also acquired Tech-IT in the 2019 first quarter, and the Company anticipates completing the accounting for the acquisition in the 2019 third quarter. The Company is also allowed to elect an irrevocable option to measure, on a contract-by-contract basis, specific financial instruments and certain other items that are currently not being measured at fair value. The Company did not elect to apply the fair value provisions of this accounting standard for any specific contracts during the quarters ended June 28, 2019 or June 29, 2018.
Life Insurance Policies	Life Insurance Policies The Company has purchased life insurance on the lives of a number of former employees who are plan participants in the non-qualified defined benefit Executive Supplemental Benefit Plan. In total, there are policies on 18 individuals, whose average age is 75 years old. Those policies have generated cash surrender value and the Company has taken loans against the policies. At June 28, 2019, these insurance policies have a gross cash surrender value of $28.8 million, outstanding loans and interest totaling $26.4 million, and a net cash surrender value of $2.4 million. At December 31, 2018, these insurance policies had a cash surrender value of $28.4 million, outstanding loans and interest totaling $25.8 million, and a net cash surrender value of $2.6 million. The net cash surrender values are included on the condensed consolidated balance sheet in “Cash surrender value of life insurance” under non-current assets. At both June 28, 2019 and December 31, 2018, the total death benefit for the remaining policies was approximately $37.6 million. Currently, upon the death of all of the remaining plan participants, the Company would expect to receive approximately $10.9 million after the payment of obligations, and, under current tax regulations, record a non-taxable gain of approximately $8.5 million.
Cash and Cash Equivalents, and Cash Overdrafts	Cash and Cash Equivalents, and Cash Overdrafts For purposes of the statement of cash flows, cash and cash equivalents are defined as cash on hand, demand deposits, and short-term, highly liquid investments with an original maturity of three months or less. As the Company does not fund its bank accounts for the checks it has written until the checks are presented to the bank for payment, the "change in cash overdraft, net," line item as presented on the condensed consolidated statements of cash flows represents the increase or decrease in outstanding checks in a given period.
Property, Equipment and Capitalized Software Costs	Property, Equipment and Capitalized Software Costs Property, equipment and capitalized software at June 28, 2019 and December 31, 2018 are summarized as follows: (amounts in thousands) June 28, 2019 December 31, 2018 Property, equipment and capitalized software $ 18,721 $ 18,292 Accumulated depreciation and amortization (13,280 ) (12,636 ) Property, equipment and capitalized software, net $ 5,441 $ 5,656 The Company recorded less than $0.1 million of capitalized software costs during both the quarter and two quarters ended June 28, 2019 and June 29, 2018, respectively. As of those dates, the Company had capitalized a total of $2.0
Goodwill	Goodwill The goodwill recorded on the Company's condensed consolidated balance sheet at June 28, 2019 relates to the acquisition of Soft Company in the 2018 first quarter, and Tech-IT in the 2019 first quarter. In accordance with current accounting guidance for “Intangibles - Goodwill and Other,” the Company performs goodwill impairment testing at least annually (in the Company’s fourth quarter), unless indicators of impairment exist in interim periods. The changes in the carrying amount of goodwill for the two quarters ended June 28, 2019 are as follows: (amounts in thousands) Balance at December 31, 2018 $ 11,664 Acquired goodwill 7,814 Foreign currency translation 10 Balance at June 28, 2019 $ 19,488

Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). On January 1, 2019, the Company adopted the new lease standard using the modified retrospective transition approach and elected the transition method to apply the new lease standard as of the January 1, 2019 adoption date. Results for the reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts are not adjusted and continue to be reported in accordance with accounting under Topic 840. In addition, the Company elected the ‘package of practical expedients’, which permits the Company not to reassess under the new standard prior conclusions about lease identification, lease classification, and initial direct costs. The Company has also elected the practical expedient to separate lease and non-lease components for its office leases and has elected to group lease and non-lease components for its vehicle leases. Upon adoption of Topic 842 on January 1, 2019, the Company recorded approximately $13.1 million of operating lease right-of-use assets and In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments”, which requires the immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, including trade receivables. This guidance is effective for reporting periods beginning after December 15, 2019; however, early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-13 will have on its condensed consolidated financial statements.
Guarantees	Guarantees The Company has a number of guarantees in place in its European operations that support office leases and performance under government contracts. At both
