Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies: Basis of Presentation References in this Annual Report on Form 10-K Description of Business We are a provider of Digital Transformation IT Services. Our portfolio of offerings include data and analytics services; other digital transformation services such as Salesforce.com and Digital Learning services; and IT staffing services that span across digital and mainstream technologies. Reflective of our 2017 acquisition of the services division of Canada-based InfoTrelllis, Inc., we have added specialized capabilities in delivering data and analytics services to our customers globally. This business offers project-based consulting services in the areas of Master Data Management, Enterprise Data Integration, Big Data, Analytics and Digital Transformation, with such services delivered using on-site Our IT staffing business combines technical expertise with business process experience to deliver a broad range of staffing services in digital and mainstream technologies. Our digital technologies include data management, analytics, cloud, mobility, social and artificial intelligence. We work with businesses and institutions with significant IT spending and recurring staffing service needs. We also support smaller organizations with their “project focused” temporary IT staffing requirements. Recent Developments On July 24, 2018, the Company’s Board of Directors declared a two-for-one Accounting Principles The Company’s Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from these estimates. Cash and Cash Equivalents Cash and cash equivalents are defined as cash and highly liquid debt investments with maturities of three months or less when purchased. Cash equivalents are stated at cost, which approximates market value. Accounts Receivable and Unbilled Receivables The Company extends credit to clients based upon management’s assessment of their creditworthiness. A substantial portion of the Company’s revenue, and the resulting accounts receivable, are from Fortune 1000 companies, major systems integrators and other staffing organizations. The Company does not generally charge interest on delinquent accounts receivable. Unbilled receivables represent amounts recognized as revenues based on services performed and, in accordance with the terms of the client contract, will be invoiced in a subsequent period. See Note 2 “Revenue from Contracts with Customers” for futher details. Allowance for Uncollectible Accounts Accounts receivable are reviewed periodically to determine the probability of loss. The Company records an allowance for uncollectible accounts when it is probable that the related receivable balance will not be collected based on historical collection experience, client-specific collection issues, and other matters the Company identifies in its collection monitoring. The Allowance for Uncollectible Accounts was $408,000 and $398,000 at December 31, 2018 and 2017, respectively. There were $10,000, $10,000 and $75,000 of bad debt expense charges for the years ended December 31, 2018, 2017 and 2016, respectively, which amounts are reflected in the Consolidated Statements of Operations. Equipment, Enterprise Software and Leasehold Improvements Equipment, enterprise software and leasehold improvements are stated at historical cost. The Company provides for depreciation using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of (a) the remaining term of the lease or (b) the estimated useful life of the improvements. Repairs and maintenance, which do not extend the useful life of the respective assets, are charged to expense as incurred. Upon disposal, assets and related accumulated depreciation are removed from the Company’s accounts and the resulting gains or losses are reflected in the Company’s Consolidated Statement of Operations. The estimated useful lives of depreciable assets are primarily as follows: Laptop Computers 18 months Equipment 3-5 years Enterprise Software 3-5 years The Company capitalizes certain external and internal computer software and software development costs incurred during the application development stage. The application development stage generally includes software design and configuration, coding, testing and installation activities. Capitalized costs include only external direct cost of material and services consumed in developing or obtaining internal-use internal-use The Company recently implemented new enterprise software applications to its backbone systems environment. As of December 31, 2018 and December 31, 2017, the Company has capitalized $1.8 million and $1.3 million, respectively, related to this endeavor, which was placed in service on July 1, 2018. The Company started amortizing these costs commencing with this go-live Depreciation and amortization expense related to fixed assets totaled $455,000, $232,000 and $203,000 for the years ended December 31, 2018, 2017 and 2016, respectively. Goodwill and Intangible Assets Identifiable intangible assets are recorded at fair value as of the closing date when acquired in a business combination. Identifiable intangible assets related to our Hudson IT and InfoTrellis acquisitions consisted of client relationships, covenants not-to-compete, Excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired are recorded as goodwill. Goodwill is not amortized but is tested for impairment at least on an annual basis. If impairment is indicated, a write-down to fair value is recorded based on the excess of the carrying value of the asset over its fair market value. We review goodwill and intangible assets for impairment annually as of October 1 st In conducting our annual impairment testing, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, we are then required to perform a quantitative impairment test. We also may elect not to perform the qualitative assessment, and instead, proceed directly to the quantitative impairment test. In 2018, we performed a quantitative impairment test related to our June 2015 acquisition of Hudson Global Resources Management, Inc.’s U.S. IT staffing business (“Hudson IT”). The results of this testing indicated no impairment associated with the carrying amount of goodwill and intangible assets. Additionally in 2018, we performed quantitative impairment tests related to our July 2017 acquisition of InfoTrellis. The results of such testing indicated impairment associated with the carrying amount of goodwill of $9.7 million. Accordingly, this goodwill impairment charge is reflected in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations in Item 8, herein. Business Combinations The Company accounts for acquisitions in accordance with guidance found in ASC 805, Business Combinations (1) in-process ASC 805 requires that any excess purchase price over fair value of assets acquired (including identifiable intangibles) and liabilities assumed be recognized as goodwill. Additionally, any excess fair value of acquired net assets over acquisition consideration results in a bargain purchase gain. Prior to recording a gain, the acquiring entity must reassess whether all acquired assets and assumed liabilities have been identified and must perform re-measurements The InfoTrellis financial results are included in the Company’s Consolidated Financial Statements from the date of the acquisition of July 13, 2017. The Hudson IT financial results are included in the Company’s Consolidated Financial Statements from the date of the acquisition of June 15, 2015. Income Taxes The Company records an estimated liability for income and other taxes based on what management determines will likely be paid in the various tax jurisdictions in which we operate. Management uses its best judgment in the determination of these amounts. However, the liabilities ultimately realized and paid are dependent on various matters, including the resolution of the tax audits in the various affected tax jurisdictions, and may differ from the amounts recorded. An adjustment to the estimated liability would be recorded through income in the period in which it becomes probable that the amount of the actual liability differs from the amount recorded. Management determines the Company’s income tax provision using the asset and liability method. Under this method, deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities. The Company measures deferred tax assets and liabilities using enacted tax rates in effect for the year in which we expect to recover or settle the temporary differences. The effect of a change in tax rates on deferred taxes is recognized in the period that the change is enacted. The Company evaluates its deferred tax assets and records a valuation allowance when, in management’s opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized. For the periods presented, no valuation allowance has been provided. In 2017, the Company incurred an estimated one-time re-measurement one-time re-measurement one-time The Company accounts for uncertain tax positions in accordance with ASC Topic 740-10, Accounting for Uncertainty in Income Taxes The Company’s 2015 federal income tax return is under audit by the Internal Revenue Service (“IRS”). During 2013, the Company’s 2011 federal income tax return was audited by the IRS, resulting in no material adjustments to its filed return. Deferred Financing Costs The Company capitalizes expenses directly related to securing its credit facilities. These deferred costs are amortized as interest expense over the term of the underlying facilities. Unamortized deferred financing costs are included as reductions in the long-term debt caption in the Consolidated Balance Sheets. Contingent Consideration Liability In connection with the InfoTrellis acquisition, the Company may be required to pay future consideration that is contingent upon the achievement of specified earnings before interest and taxes objectives (“EBIT”). As of the acquisition date, the Company recorded a contingent consideration liability representing the estimated fair value of the contingent consideration that is expected to be paid. The fair value of the contingent consideration liability was estimated by utilizing a probability weighted simulation model to determine the fair value of contingent consideration. We re-measure In 2018, the Company revalued the contingent consideration liability after determining that relevant conditions for payment of such liability were unlikely to be fully satisfied. The revaluation resulted in an $11.1 million reduction to the contingent consideration liability which is reflected in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations, in Item 8, herein. Segment Reporting Subsequent to the July 13, 2017 InfoTrellis acquisition, the Company has two reportable segments, in accordance with ASC Topic 280 “Disclosures About Segments of an Enterprise and Related Information”: Data and Analytics Services (which segment represents the acquired InfoTrellis business); and IT Staffing Services. Revenue Recognition The Company recognizes revenue on time-and-material Time-and-material out-of-pocket Out-of-pocket The Company recognizes revenue on fixed price contracts as services are rendered and uses a cost-based input method to measure progress. Determining a measure of progress requires management to make judgments that affect the timing of recognizing revenue. Under the cost-based input method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. The Company has determined that the cost-based input method provides a faithful depiction of the transfer of goods or services to the customer. Estimated losses are recognized immediately in the period in which current estimates indicate a loss. We record deferred revenues when cash payments are received or due in advance of our performance, including amounts which may be refundable. In certain situations related to client direct hire assignments, where the Company’s fee is contingent upon the hired resources’ continued employment with the client, revenue is not fully recognized until such employment conditions are satisfied. Stock-Based Compensation Effective October 1, 2008, the Company adopted a Stock Incentive Plan (the “Plan”) which, as amended, provides that up to 3,600,000 shares (adjusted for the 2018 two-for-one The Company accounts for stock-based compensation expense in accordance with ASC Topic 718 “ Share-based Payments Treasury Stock The Company maintained a stock repurchase program which expired on December 22, 2016. Under the program, the Company made treasury stock purchases in the open market, subject to market conditions and normal trading restrictions. Upon expiration, the program was not extended by the Company’s Board of Directors. Additionally, the Company makes stock purchases from time to time to satisfy employee tax obligations related to its Stock Incentive Plan. At December 31, 2018, the Company held 1.6 million shares in its treasury at a cost of approximately $4.2 million. Comprehensive Income Comprehensive income as presented in the Consolidated Statements of Comprehensive Income consists of net income, unrealized gains or losses, net of tax, on cash flow hedging transactions and foreign currency translation adjustments. Derivative Instruments and Hedging Activities – Interest Rate Swap Contracts Concurrent with the Company’s borrowings on July 13, 2017 under its new credit facility, the Company entered into an interest-rate swap to convert the debt’s variable interest rate to a fixed rate of interest. These swap contracts have been designated as cash flow hedging instruments and qualified as effective hedges at inception under ASC Topic 815, “Derivatives and Hedging”. These contracts are recognized on the balance sheet at fair value. The effective portion of the changes in fair value on these contracts is recorded in other comprehensive income (loss) and is reclassified into the Consolidated Statements of Operations as interest expense in the same period in which the underlying transaction affects earnings. With respect to derivatives designated as hedges, the Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking such transactions. The Company evaluates hedge effectiveness at the time a contract is entered into and on an ongoing basis. If a swap contract is deemed ineffective, the change in the fair value of the derivative is recorded in the Consolidated Statement of Operations as interest expense. Foreign Currency Translation The reporting currency of the Company and its subsidiaries is the U.S. dollar. The functional currency of the Company’s Indian subsidiaries is their local currency. The results of operations of the Company’s Indian subsidiaries are translated at the monthly average exchange rates prevailing during the period. The financial position of the Company’s Indian subsidiaries is translated at the current exchange rates at the end of the period, and the related translation adjustments are recorded as a component of accumulated other comprehensive income (loss) within Shareholders’ Equity. Gains and losses resulting from foreign currency transactions are included as a component of other income (expense), net in the Consolidated Statements of Operations, and have not been material for all periods presented. Earnings Per Share Basic earnings per share are computed using the weighted-average number of common shares outstanding during the period. Diluted earnings per share are computed using the weighted-average number of common shares outstanding during the period, plus the incremental shares outstanding assuming the exercise of dilutive stock options and the vesting of restricted shares and performance shares, calculated using the treasury stock method.

Revenue from Contracts with Customers	2. Revenue from Contracts with Customers As of January 1, 2018, the Company adopted ASU 2014-09, The Company recognizes revenue on time-and-material Time-and-material out-of-pocket Out-of-pocket In certain situations related to client direct hire assignments, where the Company’s fee is contingent upon the hired resources continued employment with the client, revenue is not fully recognized until such employment conditions are satisfied.

Estimated losses are recognized immediately in the period in which current estimates indicate a loss. We record deferred revenues when cash payments are received or due in advance of our performance, including amounts which may be refundable.

Business Combinations	3. Business Combinations On July 7, 2017, Mastech Digital, Inc., through its wholly-owned subsidiaries Mastech InfoTrellis, Inc., Mastech InfoTrellis Digital, Ltd., Mastech Digital Data, Inc. and Mastech Digital Private Limited (collectively, the “Company Entities”), entered into two Asset Purchase Agreements and a Share Purchase Agreement (collectively, the “Purchase Agreements”) to acquire substantially all of the assets comprising the consulting services business in the areas of master data management, data integration and big data (the “Acquired Business”) of InfoTrellis Inc., InfoTrellis, Inc. and 2291496 Ontario Inc., including all outstanding shares of InfoTrellis India Private Limited (collectively, “InfoTrellis”). The aforementioned transaction was closed on July 13, 2017. Under the terms of the Purchase Agreements, the Company Entities paid at the closing of the acquisition $35.75 million in cash, less certain working capital adjustments which totaled $861,000. The Purchase Agreements also provided for contingent consideration of $19.25 million in deferred cash payments, with up to $8.25 million payable if the EBIT of the Acquired Business for the 12-month 12-month To fund the acquisition, the Company entered into a new credit agreement on July 13, 2017 with PNC Bank, National Association, as administrative agent, swing loan lender and issuing lender, PNC Capital Markets LLC, as sole lead arranger and sole book runner, and certain financial institutions party thereto as lenders. The Credit Agreement provides for a total aggregate commitment of $65.0 million, consisting of (i) a revolving credit facility in an aggregate principal amount not to exceed $27.5 million, subject to increases to an aggregate amount not to exceed $37.5 million upon satisfaction of certain conditions; (ii) a $30.5 million term loan facility; and (iii) a $7.0 million delayed draw term loan facility to be used exclusively toward contingent consideration payments. In addition, the Company entered into Securities Purchase Agreements with Ashok Trivedi and Sunil Wadhwani (collectively, the “Investors”) on July 7, 2017 pursuant to which the Company issued and sold an aggregate 1.7 million shares (the “Shares”) of its common stock, par value $0.01 per share (the “Common Stock”), to the Investors on July 13, 2017 for $6.0 million in aggregate gross proceeds (the “Private Placement Transactions”). The Company used the proceeds from the Private Placement Transactions to fund a portion of the cash paid at the closing of the acquisition. On April 20, 2018, we entered into an amendment to the Credit Agreement. This amendment: (i) reduced the aggregate commitment amount of the revolving credit facility from $27.5 million to $22.5 million, which amount is subject to increase to an aggregate commitment amount not exceeding $32.5 million upon satisfaction of certain conditions; (ii) increased the aggregate commitment amount of the swing loan sub-facility The acquisition was accounted for using the acquisition method of accounting. The acquisition method of accounting requires that the assets acquired and liabilities assumed be measured at their fair value as of the closing date. The following table summarizes the fair value of consideration for the Acquired Business on the July 13, 2017 closing date: (in thousands) Amounts Cash purchase price at closing $ 35,750 Working capital adjustments (861 ) Estimated payout of contingent consideration (1) 17,125 Total Fair Value of Consideration $ 52,014 (1) Based on a valuation conducted by an independent third party, the fair value of contingent consideration at the closing date was determined to be $17,125,000. The cash purchase price at closing was paid with funds obtained from the following sources: (in thousands) Amounts Cash balances on hand $ 341 Sale of common stock in a private placement transactions 6,000 Term loan debt facility 30,500 Revolving line of credit 9,000 Payoff of previous credit facility (10,091 ) Cash paid at Closing $ 35,750 The allocation of the purchase price was based on estimates of the fair value of assets acquired and liabilities assumed as of July 13, 2017, as set forth below. The excess purchase price over the fair values of the net tangible assets and identifiable intangible assets was recorded as goodwill, which includes value associated with the assembled workforce. Goodwill is expected to be largely deductible for tax purposes. The valuation of net assets acquired is as follows: (in thousands) Amounts Current Assets $ 6,909 Fixed Assets and Other 215 Identifiable intangible assets: Client relationships 16,671 Covenant not-to-compete 761 Trade name 1,221 Technology 1,209 Total identifiable intangible assets 19,862 Goodwill 27,417 Current liabilities (2,389 ) Net Assets Acquired $ 52,014 The fair value of identifiable intangible assets has been estimated using the income approach through a discounted cash flow analysis. Specifically, the Company used the income approach through an excess earnings analysis to determine the fair value of client relationships. The value applied to the covenant not-to-compete The Company incurred $2.0 million of transaction expenses related to the acquisition in 2017. In 2018, the Company reversed transaction expenses of $140,000 that did not materialize. This credit expense related to investment banker fees that were tied to the contingent consideration liability. These expenses are included in selling, general and administrative expenses in the accompanying Consolidated Statement of Operations. Included in the Consolidated Statement of Operations for year ended December 31, 2017 are revenues of $9.2 million and net income of approximately $1.1 million applicable to the InfoTrellis operations from our July 13, 2017 acquisition date through December 31, 2017. The following reflects the Company’s unaudited pro forma results had the results of InfoTrellis been included for all periods presented: Years Ended December 31, 2018 2017 2016 (Amounts in Thousands, except per share data) Revenue $ 177,164 $ 158,785 $ 157,077 Net income $ 6,691 $ 2,388 $ 6,778 Earnings per share—diluted $ .60 $ .22 $ .63 The information above does not reflect all of the operating efficiencies or inefficiencies that may have resulted from the InfoTrellis acquisitions in those periods prior to the acquisition. Therefore, the unaudited pro forma information above is not necessarily indicative of results that would have been achieved had the business been combined during all periods presented.

Goodwill and Other Intangible Assets, net	4. Goodwill and Other Intangible Assets, net Goodwill related to our June 15, 2015 acquisition of Hudson IT totaled $8.4 million. Goodwill related to our July 13, 2017 acquisition of the services division of InfoTrellis totaled $27.4 million. During 2018, the Company recorded a goodwill impairment related to the InfoTrellis acquisition of $9.7 million. The impairment was attributable to a lower recovery in revenues from levels present at closing. Based upon the business performance subsequent to the acquisition date, we reduced our near-term outlook and lowered our revenue projections from original expectations. Also, we factored into our current assessment of discounted cash flows, additional investments to the sales organization and other necessary investments which were not initially considered. This revised outlook resulted in a goodwill impairment of $9.7 million for the year ended December 31, 2018. A reconciliation of the beginning and ending amounts of goodwill for the three years ended December 31, 2018 is as follows: Years Ended December 31, 2018 2017 2016 (Amounts in thousands) Goodwill, beginning balance $ 35,844 $ 8,427 $ 8,427 Addition in current period — 27,417 — Reduction in current period (9,738 ) — — Goodwill, ending balance $ 26,106 $ 35,844 $ 8,427 The Company is amortizing the identifiable intangible assets on a straight-line basis over estimated average lives ranging from 3 to 12 years.

Credit Facility On July 13, 2017, the Company entered into a Credit Agreement (the “Credit Agreement”) with PNC Bank, as administrative agent, swing loan lender and issuing lender, PNC Capital Markets LLC, as sole lead arranger and sole book-runner, and certain financial institution parties thereto as lenders (the “Lenders”). Prior to the Company entering into the April 20, 2018 amendment described below, the Credit Agreement provided for a total aggregate commitment of $65 million, consisting of (i) a revolving credit facility (the “Revolver”) in an aggregate principal amount not to exceed $27.5 million (subject to increase by up to an additional $10 million upon satisfaction of certain conditions); (ii) a $30.5 million term loan facility (the “Term Loan”); and a (iii) $7.0 million delayed draw term loan facility (the “Delayed Draw Term Loan”), as more fully described in Exhibit 10.1 to the Company’s Form 8-K, The Revolver expires in July 2022 and includes a letter of credit sub-limit On April 20, 2018, we entered into an amendment to our Credit Agreement dated as of July 13, 2017. This amendment: (i) reduced the aggregate commitment amount of the Revolver from $27.5 million to $22.5 million, which amount is subject to increase to an aggregate commitment amount not exceeding $32.5 million upon satisfaction of certain conditions; (ii) increased the aggregate commitment amount of the swing loan sub-facility 8-K Amounts borrowed under the Term Loan are required to be repaid in consecutive quarterly installments commencing on October 1, 2017 through and including July 1, 2022 and on the maturity date of July 13, 2022. The principal amount of each quarterly installment payable on the Term Loan equals the product of $30.5 million, multiplied by (i) 3.125% for quarterly installments due on October 1, 2017 through and including July 1, 2018; (ii) 3.75% for quarterly installments payable on October 1, 2018 through and including July 1, 2021; and (iii) 5.00% for quarterly installments payable on October 1, 2021 through and including the maturity date, with the maturity date payment equal to the outstanding amount of the loan on that date. The Delayed Draw Term Loan may be used through the date of the final contingent consideration payment (referred to as the final “Deferred Amount Payment” in the Credit Agreement) on no more than two separate occasions in borrowing multiples of $1.0 million up to the lesser of contingent consideration earned or $7.0 million. Amounts borrowed under the Delayed Draw Term Loan will be payable in consecutive quarterly installments commencing on the first payment date after disbursement of such borrowings. The principal amount of each quarterly installment payable of each Delayed Draw Term Loan equals the product of the original balance of such Loan, multiplied by (i) 3.75% for quarterly installments due on October 1, 2018 through and including July 1, 2021; and (ii) 5.00% for quarterly installments payable on October 1, 2021 through and including the maturity date, with the maturity date payment equal to the outstanding amount of the loan on that date. Borrowings under the revolver and the term loans, at the Company’s election, bear interest at either (a) the higher of PNC’s prime rate or the federal funds rate plus 0.50%, plus an applicable margin determined based upon the Company’s senior leverage ratio or (b) an adjusted London Interbank Offered Rate (“LIBOR”), plus an applicable margin determined based upon the Company’s senior leverage ratio. The applicable margin on the base rate is between 0.50% and 1.25% on revolver borrowings and between 1.75% and 2.50% on term loans. The applicable margin on the adjusted LIBOR is between 1.50% and 2.25% on revolver borrowings and between 2.75% and 3.50% on term loans. A 20 to 30 basis point per annum commitment fee on the unused portion of the revolver facility and the delayed draw term loan is charged and due monthly in arrears. The applicable commitment fee is determined based upon the Company’s senior leverage ratio. The Company pledged substantially all of its assets in support of the Credit Agreement. The credit agreement contains standard financial covenants, including, but not limited to, covenants related to the Company’s senior leverage ratio and fixed charge ratio (as defined under the credit agreement) and limitations on liens, indebtedness, guarantees, contingent liabilities, loans and investments, distributions, leases, asset sales, stock repurchases and mergers and acquisitions. As of December 31, 2018, the Company was in compliance with all provisions under the facility. In connection with securing the commitments under the Credit Agreement and the April 20, 2018 amendment to the Credit Agreement, the Company paid a commitment fee and incurred deferred financing costs totaling $506,000, which were capitalized and are being amortized as interest expense over the life of the facility. Deferred financing costs of $367,000 and $395,000 (net of amortization) as of December 31, 2018 and December 31, 2017, respectively, are presented as reductions in long-term debt in the Company’s Consolidated Balance Sheets. At closing, the Company borrowed $9.0 million under the Revolver and $30.5 million under the Term Loan which were used to repay all borrowings under the previous credit facility with PNC and to pay a portion of the acquisition consideration and transaction expenses. As of December 31, 2018 and 2017 the Company’s outstanding borrowings under the Revolver totaled $13.6 million and $9.0 million, respectively; and unused borrowing capacity available was approximately $9 million and $13 million, respectively. The Company’s outstanding borrowings under the term loan were $25.5 million and $29.5 million at December 31, 2018 and 2017, respectively. The Company believes the eligible borrowing base on the revolver will not fall below current outstanding borrowings for a period of time exceeding one year and has classified the $13.6 million net outstanding debt balance at December 31, 2018 as long-term. As of December 31, 2018, the annual aggregate maturities of our outstanding debt (exclusive of deferred financing costs amortization) during each of the next five years are as follows: Total Amount (Amounts in thousands) 2019 $ 4,575 2020 4,575 2021 4,956 2022 24,965 2023 — Total $ 39,071

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	11. Derivative Instruments and Hedging Activities Interest Rate Risk Management Concurrent with the Company’s July 13, 2017 borrowings under its new credit facility, the Company entered into a 44–month interest-rate swap to convert the debt’s variable interest rate to a fixed rate of interest. Under the swap contracts, the Company pays interest at a fixed rate of 1.99% and receives interest at a variable rate equal to the daily U.S. LIBOR on an initial notional amount of $15.0 million. Notional amounts were $12.6 million and $14.5 million at December 31, 2018 and 2017, respectively. These swap contracts have been designated as cash flow hedging instruments and qualified as effective hedges at inception under ASC Topic 815, “Derivatives and Hedging”. These contracts are recognized on the balance sheet at fair value. The effective portion of the changes in fair value on these instruments is recorded in other comprehensive income (loss) and is reclassified into the Consolidated Statements of Operations as interest expense in the same period in which the underlying hedge transaction affects earnings. Changes in the fair value of interest-rate swap contracts deemed ineffective are recognized in the Consolidated Statements of Operations as interest expense. Prior to July 13, 2017, the Company had outstanding interest-rate swap contracts related to term loan borrowings under the Company’s previous credit agreement. The fair value of the interest-rate swap contracts at December 31, 2018 and 2017 was an asset of $106,000 and $9,000, respectively, and is reflected in the Consolidated Balance Sheets as other current assets.

Earnings Per Share [Abstract]
Earnings per Share	13. Earnings per Share The computation of basic earnings per share (“EPS”) is based on the Company’s net income divided by the weighted average number of common shares outstanding. Diluted earnings per share reflects the potential dilution that could occur if outstanding stock options and restricted share units were exercised / released. The dilutive effect of stock options and restricted share units were calculated using the treasury stock method. For the years ended December 31, 2018, 2017 and 2016, there were 141,000, nil and 500,000 anti-dilutive stock options that were excluded from the computation of diluted earnings per share, respectively. The following table sets forth the denominators of the basic and diluted EPS computations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	14. Fair Value Measurements The Company has adopted the provisions of ASC 820, “ Fair Value Measurements and Disclosures • Level 1 – Inputs are observable quoted prices (unadjusted) in active markets for identical assets and liabilities. • Level 2 – Inputs are observable, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are directly or indirectly observable in the marketplace. • Level 3 – Inputs are unobservable that are supported by little or no market activity. The following table summarizes the basis used to measure financial assets and (liabilities) at fair value on a recurring basis: Fair Value as of December 31, 2018 (Amounts in thousands) Level 1 Level 2 Level 3 Total Interest-Rate Swap Contracts $ — $ 106 $ — $ 106 Contingent consideration liabilities $ — $ — $ (6,069 ) $ (6,069 ) Fair Value as of December 31, 2017 (Amounts in thousands) Level 1 Level 2 Level 3 Total Interest-Rate Swap Contracts $ — $ 9 $ — $ 9 Contingent consideration liabilities $ — $ — $ (17,125 ) $ (17,125 ) The fair value of interest rate swap contracts are based on quoted prices for similar instruments from a commercial bank, and therefore, the fair value measurement is considered to be within Level 2. The fair value of the contingent consideration liability was estimated by utilizing a probability weighted simulation model to determine the fair value of contingent consideration, and therefore, the fair value measurement is considered to be within Level 3. In 2018, the Company revalued the contingent consideration liability after determining that relevant conditions for payment of such liability were unlikely to be fully satisfied. The revaluation resulted in an $11.1 million reduction to the contingent consideration liability which is reflected in selling and administrative expenses in the Company’s Consolidated Statements of Operations, in Item 8 herein. The following table provides information regarding changes in the Company’s Level 3 fair values for the contingent consideration liability for the three years ended December 31, 2018: Years Ended December 31, 2018 2017 2016 (Amounts in thousands) Beginning balance $ 17,125 $ — $ — Contingent consideration incurred — 17,125 — Payments made — — — Revaluation (11,056 ) — — Ending balance $ 6,069 $ 17,125 $ — At December 31, 2018 and December 31, 2017, the Company carried the following financial assets (liabilities) at fair value measured on a non-recurring Fair Value as of December 31, 2018 (Amounts in thousands) Level 1 Level 2 Level 3 Total Goodwill $ — $ — $ 26,106 $ 26,106 Fair Value as of December 31, 2017 (Amounts in thousands) Level 1 Level 2 Level 3 Total Goodwill $ — $ — $ 35,844 $ 35,844 During the year ended December 31, 2018, the Company recorded a goodwill impairment related to the InfoTrellis acquisition of $9.7 million.

Recent Developments	Recent Developments On July 24, 2018, the Company’s Board of Directors declared a two-for-one
Accounting Principles	Accounting Principles The Company’s Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. Actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents are defined as cash and highly liquid debt investments with maturities of three months or less when purchased. Cash equivalents are stated at cost, which approximates market value.
Accounts Receivable and Unbilled Receivables	Accounts Receivable and Unbilled Receivables The Company extends credit to clients based upon management’s assessment of their creditworthiness. A substantial portion of the Company’s revenue, and the resulting accounts receivable, are from Fortune 1000 companies, major systems integrators and other staffing organizations. The Company does not generally charge interest on delinquent accounts receivable. Unbilled receivables represent amounts recognized as revenues based on services performed and, in accordance with the terms of the client contract, will be invoiced in a subsequent period. See Note 2 “Revenue from Contracts with Customers” for futher details.
Allowance for Uncollectible Accounts	Allowance for Uncollectible Accounts Accounts receivable are reviewed periodically to determine the probability of loss. The Company records an allowance for uncollectible accounts when it is probable that the related receivable balance will not be collected based on historical collection experience, client-specific collection issues, and other matters the Company identifies in its collection monitoring. The Allowance for Uncollectible Accounts was $408,000 and $398,000 at December 31, 2018 and 2017, respectively. There were $10,000, $10,000 and $75,000 of bad debt expense charges for the years ended December 31, 2018, 2017 and 2016, respectively, which amounts are reflected in the Consolidated Statements of Operations.
Equipment, Enterprise Software and Leasehold Improvements	Equipment, Enterprise Software and Leasehold Improvements Equipment, enterprise software and leasehold improvements are stated at historical cost. The Company provides for depreciation using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of (a) the remaining term of the lease or (b) the estimated useful life of the improvements. Repairs and maintenance, which do not extend the useful life of the respective assets, are charged to expense as incurred. Upon disposal, assets and related accumulated depreciation are removed from the Company’s accounts and the resulting gains or losses are reflected in the Company’s Consolidated Statement of Operations. The estimated useful lives of depreciable assets are primarily as follows: Laptop Computers 18 months Equipment 3-5 years Enterprise Software 3-5 years The Company capitalizes certain external and internal computer software and software development costs incurred during the application development stage. The application development stage generally includes software design and configuration, coding, testing and installation activities. Capitalized costs include only external direct cost of material and services consumed in developing or obtaining internal-use internal-use The Company recently implemented new enterprise software applications to its backbone systems environment. As of December 31, 2018 and December 31, 2017, the Company has capitalized $1.8 million and $1.3 million, respectively, related to this endeavor, which was placed in service on July 1, 2018. The Company started amortizing these costs commencing with this go-live Depreciation and amortization expense related to fixed assets totaled $455,000, $232,000 and $203,000 for the years ended December 31, 2018, 2017 and 2016, respectively.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Identifiable intangible assets are recorded at fair value as of the closing date when acquired in a business combination. Identifiable intangible assets related to our Hudson IT and InfoTrellis acquisitions consisted of client relationships, covenants not-to-compete, Excess purchase price over the fair value of net tangible assets and identifiable intangible assets acquired are recorded as goodwill. Goodwill is not amortized but is tested for impairment at least on an annual basis. If impairment is indicated, a write-down to fair value is recorded based on the excess of the carrying value of the asset over its fair market value. We review goodwill and intangible assets for impairment annually as of October 1 st In conducting our annual impairment testing, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not (more than 50%) that the estimated fair value of a reporting unit is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, we are then required to perform a quantitative impairment test. We also may elect not to perform the qualitative assessment, and instead, proceed directly to the quantitative impairment test. In 2018, we performed a quantitative impairment test related to our June 2015 acquisition of Hudson Global Resources Management, Inc.’s U.S. IT staffing business (“Hudson IT”). The results of this testing indicated no impairment associated with the carrying amount of goodwill and intangible assets. Additionally in 2018, we performed quantitative impairment tests related to our July 2017 acquisition of InfoTrellis. The results of such testing indicated impairment associated with the carrying amount of goodwill of $9.7 million. Accordingly, this goodwill impairment charge is reflected in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations in Item 8, herein.
Business Combinations	Business Combinations The Company accounts for acquisitions in accordance with guidance found in ASC 805, Business Combinations (1) in-process ASC 805 requires that any excess purchase price over fair value of assets acquired (including identifiable intangibles) and liabilities assumed be recognized as goodwill. Additionally, any excess fair value of acquired net assets over acquisition consideration results in a bargain purchase gain. Prior to recording a gain, the acquiring entity must reassess whether all acquired assets and assumed liabilities have been identified and must perform re-measurements The InfoTrellis financial results are included in the Company’s Consolidated Financial Statements from the date of the acquisition of July 13, 2017. The Hudson IT financial results are included in the Company’s Consolidated Financial Statements from the date of the acquisition of June 15, 2015.
Income Taxes	Income Taxes The Company records an estimated liability for income and other taxes based on what management determines will likely be paid in the various tax jurisdictions in which we operate. Management uses its best judgment in the determination of these amounts. However, the liabilities ultimately realized and paid are dependent on various matters, including the resolution of the tax audits in the various affected tax jurisdictions, and may differ from the amounts recorded. An adjustment to the estimated liability would be recorded through income in the period in which it becomes probable that the amount of the actual liability differs from the amount recorded. Management determines the Company’s income tax provision using the asset and liability method. Under this method, deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities. The Company measures deferred tax assets and liabilities using enacted tax rates in effect for the year in which we expect to recover or settle the temporary differences. The effect of a change in tax rates on deferred taxes is recognized in the period that the change is enacted. The Company evaluates its deferred tax assets and records a valuation allowance when, in management’s opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized. For the periods presented, no valuation allowance has been provided. In 2017, the Company incurred an estimated one-time re-measurement one-time re-measurement one-time The Company accounts for uncertain tax positions in accordance with ASC Topic 740-10, Accounting for Uncertainty in Income Taxes The Company’s 2015 federal income tax return is under audit by the Internal Revenue Service (“IRS”). During 2013, the Company’s 2011 federal income tax return was audited by the IRS, resulting in no material adjustments to its filed return.
Deferred Financing Costs	Deferred Financing Costs The Company capitalizes expenses directly related to securing its credit facilities. These deferred costs are amortized as interest expense over the term of the underlying facilities. Unamortized deferred financing costs are included as reductions in the long-term debt caption in the Consolidated Balance Sheets.
Contingent Consideration Liability	Contingent Consideration Liability In connection with the InfoTrellis acquisition, the Company may be required to pay future consideration that is contingent upon the achievement of specified earnings before interest and taxes objectives (“EBIT”). As of the acquisition date, the Company recorded a contingent consideration liability representing the estimated fair value of the contingent consideration that is expected to be paid. The fair value of the contingent consideration liability was estimated by utilizing a probability weighted simulation model to determine the fair value of contingent consideration. We re-measure In 2018, the Company revalued the contingent consideration liability after determining that relevant conditions for payment of such liability were unlikely to be fully satisfied. The revaluation resulted in an $11.1 million reduction to the contingent consideration liability which is reflected in selling, general and administrative expenses in the Company’s Consolidated Statements of Operations, in Item 8, herein.
Segment Reporting	Segment Reporting Subsequent to the July 13, 2017 InfoTrellis acquisition, the Company has two reportable segments, in accordance with ASC Topic 280 “Disclosures About Segments of an Enterprise and Related Information”: Data and Analytics Services (which segment represents the acquired InfoTrellis business); and IT Staffing Services.
Revenue Recognition	Revenue Recognition The Company recognizes revenue on time-and-material Time-and-material out-of-pocket Out-of-pocket The Company recognizes revenue on fixed price contracts as services are rendered and uses a cost-based input method to measure progress. Determining a measure of progress requires management to make judgments that affect the timing of recognizing revenue. Under the cost-based input method, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. The Company has determined that the cost-based input method provides a faithful depiction of the transfer of goods or services to the customer. Estimated losses are recognized immediately in the period in which current estimates indicate a loss.
