SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly ‑owned subsidiaries. These consolidated financial statements and footnotes are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, references to the Company include ISG and its consolidated subsidiaries. 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 the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates. The complexity of the estimation process and issues related to the assumptions, risks and uncertainties inherent in the application of the proportional performance method of accounting affect the amounts of revenues, expenses, unbilled receivables and deferred revenue. Numerous internal and external factors can affect estimates. Estimates are also used for but not limited to: allowance for doubtful accounts, useful lives of furniture, fixtures and equipment and definite ‑lived intangible assets, depreciation expense, fair value assumptions in analyzing goodwill and intangible asset impairments, income taxes and deferred tax asset valuation, and the valuation of stock based compensation. Business Combinations We have acquired businesses critical to the Company’s long ‑term growth strategy. Results of operations for acquisitions are included in the accompanying consolidated statement of comprehensive income from the date of acquisition. Acquisitions are accounted for using the purchase method of accounting and the purchase price is allocated to the net assets acquired based upon their estimated fair values at the date of acquisition. The excess of the purchase price over the net assets was recorded as goodwill. Acquisition-related costs are expensed as incurred and recorded in selling, general and administrative expenses. Final valuations of assets and liabilities are obtained and recorded within one year from the date of the acquisition. Cash and Cash Equivalents The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents, including certain money market accounts. The Company principally maintains its cash in money market and bank deposit accounts in the United States of America which typically exceed applicable insurance limits. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents. Restricted Cash Restricted cash consists of cash and cash equivalents which the Company has pledged to fulfill certain obligations and are not available for general corporate purposes. Accounts and Unbilled Receivables and Allowance for Doubtful Accounts Our trade receivables primarily consist of amounts due for services already performed via fixed fee or time and materials arrangements. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of clients to pay fees or for disputes that affect its ability to fully collect billed accounts receivable. The allowance for these risks is prepared by reviewing the status of all accounts and recording reserves on a specific identification method based on previous experiences and historical bad debts. However, our actual experience may vary significantly from these estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay their invoices, we may need to record additional allowances or write ‑offs in future periods. To the extent the provision relates to a client’s inability or unwillingness to make required payments, the provision is recorded as bad debt expense, which is classified within selling, general and administrative expense in the accompanying consolidated statement of comprehensive income. The provision for unbilled services is recorded as a reduction to revenues to the extent the provision relates to fee adjustments and other discretionary pricing adjustments. Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of prepaid expenses for insurance, conferences and deposits for facilities, programs and promotion items. Furniture, Fixtures and Equipment, net Furniture, fixtures and equipment is recorded at cost. Depreciation is computed by applying the straight ‑line method over the estimated useful life of the assets, which ranges from three to five years. Leasehold improvements are depreciated over the lesser of the useful life of the underlying asset or the lease term, which generally range from three to five years. Expenditures for renewals and betterments are capitalized. Repairs and maintenance are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and any associated gain or loss thereon is reflected in the accompanying consolidated statement of comprehensive income. Internal ‑Use Software and Website Development Costs The Company capitalizes internal ‑use software and website development costs and records these amounts within furniture, fixtures and equipment. Accounting standards require that certain costs related to the development or purchase of internal ‑use software and systems as well as the costs incurred in the application development stage related to its website be capitalized and amortized over the estimated useful life of the software or system. They also require that costs related to the preliminary project stage, data conversion and post implementation/operation stage of an internal ‑use software development project be expensed as incurred. During the years ended December 31, 2015, 2014 and 2013, the Company capitalized $0.3 million, $0.6 million and $0.7 million, respectively, of costs associated with the system conversion and website development. Goodwill Our goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired at the date of acquisition. Goodwill is not amortized but rather tested for impairment at least annually by applying a fair ‑value based test in accordance with accounting and disclosure requirements for goodwill and other indefinite ‑lived intangible assets. This test is performed by us during our fourth fiscal quarter or more frequently if we believe impairment indicators are present. We performed step one of a two ‑step impairment test on goodwill. Step one compares the fair value of the reporting unit to its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test whereby the carrying value of the reporting unit’s goodwill is compared to its implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference is recorded. In performing the first step of the impairment test on goodwill, we determined the fair value of the reporting unit using both a market and income approach. The income approach utilizes a discounted cash flow model and is based on projections of future operations of the reporting unit as of the valuation date. The market approach is based on our stock price and provides a direct indication of fair value. Under the market approach, we determined the fair value of the reporting unit utilizing a relevant average of our common stock price for the October 31 measurement period, as quoted on the Nasdaq Global Market plus a 35% control premium based upon recent transactions of comparable companies. The discounted cash flow model assumed revenue growth rates of approximately 3% per year. We employed a discount rate of 13.5% to discount future excess cash flows. As a result of the step one test performed, the fair value of our reporting substantially unit exceeded the carrying value. Therefore, step two was not performed or required. Long ‑Lived Assets Long ‑lived assets, excluding goodwill and indefinite ‑lived intangibles, to be held and used by the Company are reviewed to determine whether any significant change in the long ‑lived asset’s physical condition, a change in industry conditions or a reduction in cash flows associated with the use of the long ‑lived asset. If these or other factors indicate the carrying amount of the asset may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset. The fair value of the asset is measured using market prices or, in the absence of market prices, an estimate of discounted cash flows. Cash flows are generally discounted at an interest rate commensurate with our weighted average cost of capital for a similar asset. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria of accounting and disclosure requirement for the impairment or disposal of long ‑lived assets. Debt Issuance Costs Costs directly incurred in obtaining long ‑term financing, typically bank and attorney fees, are deferred and are amortized over the life of the related loan using the effective interest method. Deferred issuance costs are classified as other assets in the accompanying consolidated balance sheet. Amortization of debt issuance costs is included in interest expense and totaled $ 0.1 million, $0.2 million and $0.2 million for the years ended December 31, 2015, 2014 and 2013, respectively. Revenue Recognition We recognize our revenues for the sale of services and products when persuasive evidence of an arrangement exists, services have been rendered or delivery has occurred, the fee is fixed or determinable and the collectability of the related revenue is reasonably assured. We principally derive revenues from fees for services generated on a project ‑by ‑project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. It is our policy to obtain written agreements from new clients prior to performing services. In these agreements, the clients acknowledge that they will pay based upon the amount of time spent on the project or an agreed upon fee structure. Revenues for services rendered are recognized on a time and materials basis or on a fixed ‑fee or capped ‑fee basis in accordance with accounting and disclosure requirements for revenue recognition. Fees for services that have been performed, but for which we have not invoiced the customers are recorded as unbilled receivables in the accompanying consolidated balance sheets. Revenues from subscription contracts are recognized ratably over the life of the contract, which is generally one year. These fees are typically billed in advance and included in deferred revenue until recognized. Revenues for time and materials contracts are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project. Revenues related to fixed ‑fee or capped ‑fee contracts are recognized into revenue as value is delivered to the customer. The pattern of revenue recognition for these contracts varies depending on the terms of the individual contracts, and may be recognized proportionally over the term of the contract or deferred until the end of the contract term and recognized when our obligations have been fulfilled with the customer. In instances where substantive acceptance provisions are specified in customer contracts, revenues are deferred until all acceptance criteria have been met. The pattern of revenue recognition for contracts where revenues are recognized proportionally over the term of the contact is based on the proportional performance method of accounting using the ratio of labor hours incurred to estimated total labor hours, which we consider to be the best available indicator of the pattern and timing in which contract obligations are fulfilled. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted amount used in this calculation typically excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed our original estimate as a result of an increase in project scope or unforeseen events. On a regular basis, we review the hours incurred and estimated total labor hours to complete. The results of any revisions in these estimates are reflected in the period in which they become known. We believe we have demonstrated a history of successfully estimating the total labor hours to complete a project. The agreements entered into in connection with a project, whether on a time and materials basis or fixed ‑fee or capped ‑fee basis, typically allow our clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by us through the effective date of the termination. In addition, from time to time, we enter into agreements with clients that limit our right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit us from performing a defined range of services that it might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team. Reimbursable Expenditures Amounts billed to customers for reimbursable expenditures are included in revenues and the associated costs incurred by the Company are included in direct costs and expenses for advisors in the accompanying consolidated statement of comprehensive income. Non ‑reimbursable amounts are expensed as incurred. Reimbursable expenditures totaled $10.1 million, $9.9 million and $10.4 million for the years ended December 31, 2015, 2014 and 2013, respectively. Direct Costs and Expenses for Advisors Direct costs and expenses for advisors include payroll expenses and advisory fees directly associated with the generation of revenues and other program expenses. Direct costs and expenses for advisors are expensed as incurred. Direct costs and expenses for advisors also include expense accruals for discretionary bonus payments. Bonus accrual levels are adjusted throughout the year based on actual and projected individual and Company performance. Stock ‑Based Compensation We grant restricted stock with a fair value that is determined based on the closing price of our common stock on the date of grant. Restricted stock generally vests over a four -year period for employees and a three -year period for directors. Stock ‑based compensation expense is recognized ratably over the applicable service period. We follow the provisions of accounting and disclosures requirement for share-based payments, requiring the measurement and recognition of all share ‑based compensation under the fair value method. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and accounts receivable. The Company places its cash investments with high quality financial institutions. The Company extends credit to its customers based upon an evaluation of the customer’s financial condition and credit history and generally does not require collateral. Treasury Stock The Company makes treasury stock purchases in the open market pursuant to the share repurchase program, which was approved by the Board of Directors on May 6, 2014. Treasury stock is recorded on the consolidated balance sheet at cost as a reduction of stockholders’ equity. Shares are released from Treasury at original cost on a first ‑in, first ‑out basis, with any gain on the sale reflected as an adjustment to additional paid ‑in capital. Losses are reflected as an adjustment to additional paid ‑in capital to the extent of gains previously recognized, otherwise as an adjustment to retained earnings. Foreign Currency Translation The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the end of the reporting period. Revenue and expense items are translated at average exchange rates for the reporting period. Resulting translation adjustments are included in the accompanying statement of comprehensive income and accompanying statement of stockholders’ equity as a component of Accumulated Other Comprehensive Loss . The functional currency of the Company and its subsidiaries is the respective local currency. The Company has contracts denominated in foreign currencies and therefore, a portion of the Company’s revenues are subject to foreign currency risks. Transactional currency gains and losses that arise from transactions denominated in currencies other than the functional currencies of our operations are recorded in Foreign Currency Transaction Loss in the accompanying consolidated statement of comprehensive income. Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, receivables, accounts payable, other current liabilities, and accrued interest approximate fair value. Fair value measurements were applied with respect to our nonfinancial assets and liabilities measured on a nonrecurring basis, which would consist of measurements primarily to goodwill, intangible assets and other long ‑lived assets, and assets acquired and liabilities assumed in a business combination. Fair value is the price that would be received upon a sale of an asset or paid upon a transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). Market participants can use market data or assumptions in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market ‑corroborated, or generally unobservable. The use of unobservable inputs is intended to allow for fair value determinations in situations where there is little, if any, market activity for the asset or liability at the measurement date. Under the fair ‑value hierarchy: · Level 1 measurements include unadjusted quoted market prices for identical assets or liabilities in an active market; · Level 2 measurements include quoted market prices for identical assets or liabilities in an active market that have been adjusted for items such as effects of restrictions for transferability and those that are not quoted but are observable through corroboration with observable market data, including quoted market prices for similar assets; and · Level 3 measurements include those that are unobservable and of a highly subjective measure. During 2015, there were no transfers of our financial assets between Level 1 and Level 2 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables summarize assets and liabilities measured at fair value on a recurring basis at the dates indicated: Basis of Fair Value Measurements 12/31/2015 Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ $ — $ — $ Total $ $ — $ — $ Liabilities: Contingent consideration (1) $ — $ — $ $ Long-term debt, including current portion — — $ — $ — $ $ Basis of Fair Value Measurements 12/31/2014 Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ $ — $ — $ Total $ $ — $ — $ Liabilities: Contingent consideration (1) $ — $ — $ $ Long-term debt, including current portion — — $ — $ — $ $ (1) The short-term portion is included in “accrued expenses.” The long-term portion is included in “Other liabilities.” The fair value measurement of this contingent consideration is classified within Level 3 of the fair value hierarchy and reflects the Company’s own assumptions in measuring fair values using the income approach. In developing these estimates, the Company considered certain performance projections, historical results, and industry trends. This amount was estimated through a valuation model that incorporated probability-weighted assumptions related to the achievement of these milestones and the likelihood of the Company making payments. These cash outflow projections have then been discounted using a rate ranging from 2.3% to 14.5% . The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair values of debt have been estimated using a discounted cash flow analysis based on the Company's incremental borrowing rate for similar borrowing arrangements. The incremental borrowing rate used to discount future cash flows ranged from 2.46% to 2.74% . The Company also considered recent transactions of peer group companies for similar instruments with comparable terms and maturities as well as an analysis of current market conditions. The following table represents the change in the contingent consideration liability during the years ended December 31, 2015 and 2014: December 31, 2015 2014 Beginning Balance $ $ Payment of contingent consideration Acquisition Change in fair value of contingent consideration Accretion of contingent consideration Unrealized loss related to currency translation Ending Balance $ $ Dividend On December 2, 2014 the Board of Directors authorized a special dividend of $0.14 per share on the Company’s issued and outstanding shares of common stock. This cash dividend of $5.2 million was paid on January 28, 2015 to shareholders of record as of January 15, 2015. Prior to this special dividend we had not paid any dividends on our common stock. Income Taxes We use the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. We review our deferred tax assets for recovery. A valuation allowance is established when we believe that it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in our tax provision in the period of change. For uncertain tax positions, we use a prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in its tax returns. The guidance provides clarification on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as the related interest. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance that outlines a single comprehensive model for entities to use in accounting for revenue. Under the guidance, revenue is recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard is effective for public entities with annual and interim reporting periods beginning after December 15, 2016. On July 9, 2015, the FASB approved the deferral of the effective date of the new revenue guidance by one year to annual reporting periods beginning after December 15, 2017, with early adoption being permitted for annual periods beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt the guidance. We are currently assessing the effects this guidance may have on our consolidated financial statements, as well as the method of transition that we will use in adopting the new standard. In April 2015, the FASB issued guidance require the presentation of debt issuance costs in financial statements as a direct reduction of related debt liabilities with amortization of debt issuance costs reported as interest expense. Under current U.S. GAAP standards, debt issuance costs are reported as deferred charges (i.e., as an asset). In August 2015, the FASB clarified the guidance that debt issuance costs related to line-of-credit arrangements could continue to be presented as an asset and be subsequently amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the arrangement. This guidance is effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2015 and is to be applied retrospectively upon adoption. Early adoption is permitted, including adoption in an interim period for financial statements that have not been previously issued. At December 31, 2015, the Company had debt issuance costs of $0.6 million. In September 2015, the FASB issued updated guidance, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Acquirers must recognize measurement-period adjustments during the period of resolution, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The updated guidance is effective for fiscal years beginning after December 15, 2015. Earlier adoption is permitted for any interim and annual financial statements that have not yet been issued. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In November 2015, the FASB issued an accounting standards update to simplify the presentation of deferred income taxes on the balance sheet. The update requires that all deferred tax assets and liabilities be classified as noncurrent. The current guidance that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not impacted by this update. The provisions of the new standard are effective beginning January 1, 2017, for annual and interim periods and early adoption is permitted. We do not expect the adoption of this guidance to have a material impact on our results of operations, but will result in a reclassification of current net deferred tax on our balance sheet in future years. Adoption of the guidance as of December 31, 2015 would result in a reclassification of current net deferred tax of $2.1 million and $1.1 million as of December 31, 2015 and 2014, respectively.

ACQUISITIONS	NOTE 3—ACQUISITIONS Saugatuck Technology Acquisition On August 7, 2015 (the “Saugatuck Acquisition Date”), the Company executed an Asset Purchase Agreement (the “Saugatuck Agreement”) by and among Saugatuck Technology Inc. (“Saugatuck”), ISG Information Services Group Americas, Inc. , a wholly-owned subsidiary of ISG (“Buyer”), and the other parties thereto and consummated the acquisition of substantially all of the assets, and assumption of certain current liabilities, excluding debt and employee loans of Saugatuck. Saugatuck is a subscription-based research and analyst firm that provides C-level executives and technology business leaders with objective insights on the key market trends and emerging technologies that are driving business transformation and growth. Saugatuck’s deep intellectual capital, respected analytical and forecasting capabilities, and influential market insights and opinions complement our growing Cloud, Digital and Automation consulting practices. Under the terms of the Saugatuck Agreement, we acquired the specified assets for aggregate cash and stock consideration of $0.7 million (net of cash received) consisting of $0.5 million in cash and $0.2 million in stock at closing. In addition, Saugatuck is eligible to receive a minimum of $0 and a maximum of up to $1.3 million of earn-out payments for fiscal years 2015-2018 if certain revenue targets are met, payable in a combination of cash and stock. The following table summarizes the consideration transferred to acquire Saugatuck and the amounts of identified assets acquired and liabilities assumed as of the Saugatuck Acquisition Date: The preliminary allocable purchase price consists of the following: Cash $ Restricted stock* Contingent consideration Total allocable purchase price $ * 33,784 shares at $4.44 at close of market on August 7, 2015. Recognized amounts of identifiable assets acquired and liabilities assumed as of the Saugatuck Acquisition Date: Cash $ Accounts receivable Other assets Intangible assets Accrued expenses and other Net assets acquired $ Goodwill (1) $ (1) Goodwill of approximately $1.1 million acquired in the acquisition is deductible for tax purposes. Costs associated with this acquisition are included in the selling, general and administrative expenses in the consolidated statement of comprehensive income and totaled $0.1 million during the year December 31 , 2015. This business combination was accounted for under the acquisition method of accounting, and as such, the aggregate purchase price was allocated on a preliminary basis to the assets acquired and liabilities assumed based on estimated fair values as of the closing dates. The purchase price allocations will be finalized after the completion of the valuation of certain intangible assets and any adjustments to the preliminary purchase price allocations are not expected to have a material impact on the Company’s results of operations. Based on the valuation and other factors as described above, the purchase price assigned to intangible assets and the amortization period were as follows: Purchase Price Allocation Asset Life Amortizable intangible assets: Customer relationships $ years Non-compete years Total intangible assets $ The Consolidated Financial Statements include the results of Saugatuck acquisition subsequent to the closing. If the acquisition occurred as of January 1, 2014, the impact on the Company’s results of operations would not have been material. CCI Acquisition On April 15, 2014, Technology Partners International, Inc., a wholly-owned subsidiary of ISG, executed an Asset Purchase Agreement (the “CCI Agreement”) with CCI, and consummated the acquisition of substantially all of the assets and assumption of certain liabilities of CCI. CCI is a Melbourne, Australia-based research firm that measures and analyzes customer satisfaction in business-to-business relationships. The agreement with CCI extends our global penetration into recurring revenue businesses in Asia Pacific. CCI’s products are a natural complement to our “Assess” capabilities that analyze service performance and cost metrics. Under the terms of the CCI Agreement, ISG acquired the assets for cash consideration of AU$1.9 million, of which AU$1.0 million was paid at closing and AU$0.9 million was paid in April 2015. In addition, the sellers under the CCI Agreement (the “CCI Sellers”) are eligible to receive a minimum of AU$0 and a maximum up to AU$3.0 million of earn-out payments for fiscal years 2014-2016 if certain earnings targets are met. Finally, the CCI Sellers were granted 50,000 ISG Restricted Shares that will vest if certain target revenues of ISG and its affiliates are met. The following table summarizes the consideration transferred to acquire CCI and the amounts of identified assets acquired and liabilities assumed at the acquisition date: The final allocable purchase price consists of the following: Cash $ Post-completion installment payment Restricted stock* Contingent consideration Working capital adjustment Total allocable purchase price $ * 50,000 shares at $4.74 at close of market on 4/15/2014 that vest upon achievement of certain performance measures.

Costs associated with this acquisition are included in the selling, general and administrative expenses in the consolidated statement of comprehensive income and totaled $0.2 million during the year ended December 31, 2014. This business combination was accounted for under the acquisition method of accounting, and as such, the aggregate purchase price was allocated on a basis to the assets acquired and liabilities assumed based on estimated fair values as of the closing dates. Based on the valuation and other factors as described above, the purchase price assigned to intangible assets and the amortization period were as follows: Purchase Price Allocation Asset Life Amortizable intangible assets: Customer relationships $ years Databases years Backlog years Total intangible assets $ The Consolidated Financial Statements include the results of the CTP and CCI acquisition subsequent to the closing. If the acquisition occurred as of January 1, 2013, the impact on the Company’s results of operations would not have been material. CTP Acquisition On March 17, 2014, Compass Holding BV, a wholly-owned subsidiary of ISG entered into an Agreement with Convergent Technologies Partners S.p.A. (“CTP”) whereby Compass Holding BV acquired 51% of CTP’s share capital for $1.0 million, which included $0.7 million of cash acquired, providing the Company with control over CTP. CTP became a subsidiary of the Company on the date of acquisition. At the same time CTP acquired 100% interest of Compass Management Consulting Italy “Compass Italy”, a subsidiary of Compass Holding BV for $0.3 million. The selling of Compass Italy and acquisition of CTP are treated as linked transactions and accordingly recorded on a net basis. The Company is consolidating the financial results of CTP in its consolidated financial statements and accordingly, reported revenues, costs and expenses, assets and liabilities, and cash flows include 100% of CTP, with the 49% noncontrolling interest share reported as net income attributable to noncontrolling interest in the consolidated statements of operations, and redeemable noncontrolling interest on the consolidated balance sheets. CTP is a leading management consulting firm providing specialized IT and operational strategies and solutions to Italy’s public sector. The agreement with CTP extends our global penetration into the public sector, building on our successful public sector businesses in North America, Australia and the UK. It also provides new growth opportunities for the Company to serve both public and private sector organizations in Italy with our combined resources. The parties also executed a put and call option agreement for the transfer to ISG of all of the outstanding CTP’s share capital that it does not own, exercisable upon certain conditions. The remaining 49% ownership in CTP is held by a third party. The third party representing the redeemable non-controlling interest in the subsidiary holds put rights for the remaining interest in CTP and the Company holds call rights with respect to such remaining interest. The put right provides the third party an option to sell its ownership interest to the Company after December 31, 2016 at a price based on four times the average of Earning Before Interests, Taxes, Depreciation and Amortization (“EBITDA”) and for the year 2015 and year 2016, as resulting from CTP’s approved financial statements for the year 2015 and year 2016 at the time of the exercise. Because the redeemable non-controlling interest in CTP has a redemption feature, as a result of the put option, the Company has classified the redeemable non-controlling interest in CTP in the mezzanine section of the Consolidated Balance Sheet. The redeemable non-controlling interest will be accreted to the redemption value by recording a corresponding adjustment to accumulated deficit at the end of each reporting period. The following table summarizes the consideration transferred to acquire CTP and the amounts of identified assets acquired and liabilities assumed at the acquisition date, as well as the fair value of the redeemable noncontrolling interest in CTP at the acquisition date: Fair value of consideration transferred: Cash $ Redeemable noncontrolling interest* Total fair value transferred $ * Equivalent to 49% of CTP’s share capital discounted for lack of control and marketability based on third party research. Recognized amounts of identifiable assets acquired and liabilities assumed as of March 17, 2014: Cash $ Accounts receivable Other assets Intangible assets Accounts payable Accrued expenses and other Net assets acquired $ Bargain purchase gain $ This bargain purchase gain resulted as the fair value of the net assets acquired exceeded the consideration transferred. The excess resulted from the fact that the seller was motivated to sell. Costs associated with this acquisition are included in the selling, general and administrative expenses in the consolidated statement of comprehensive income and totaled $0.2 million during the year ended December 31, 2014. This business combination was accounted for under the acquisition method of accounting, and as such, the aggregate purchase price was allocated to the assets acquired and liabilities assumed based on estimated fair values as of the closing dates.

NET INCOME PER COMMON SHARE
NET INCOME PER COMMON SHARE	NOTE 4— NET INCOME PER COMMON SHARE Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. The 50,000 contingently issuable/restricted shares related to the acquisition of CCI were excluded from basic and diluted earnings p er share since the contingency had not been met as of the reporting period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that would share in the net income of the Company. For the year ended December 31, 2015, the effect of 0.1 million stock appreciation rights (“SARs”) have not been considered in the diluted earnings per share, since the market price of the stock was less than the exercise price during the period in the computation. In addition, 0.5 million restricted shares have not been considered in the diluted earnings per share calculation for the year ended December 31, 2015, as the effect would be anti-dilutive. For the year ended December 31, 2014, the effect of 0.1 million SARs have not been considered in the diluted earnings per share, since the market price of the stock was less than the exercise price during the period in the computation. For the year ended December 31, 2013, the effect of 0.1 million SARs have not been considered in the diluted earnings per share, since the market price of the stock was less than the exercise price during the period in the computation. In addition, 0.8 million restricted shares have not been considered in the diluted earnings per share calculation for the year ended December 31, 2013 , as the effect would be anti ‑ dilutive.

On May 3 , 2013 , the Company borrowed $55.0 million under the 2013 Credit Agreement to refinance our existing debt under our prior credit agreement and to pay transaction costs. On May 11, 2015, the Company amended the 2013 Credit Agreement to reduce annual mandatory principal payments, lower borrowing costs and extend the term of the 2013 Credit Agreement by two years, resulting in a maturity date of May 3, 2020. As a result of the amendment, the Term Loan is repayable in twenty consecutive quarterly installments of $562,500 each, which commenced June 30, 2015. In add ition, the amendment also allowed the Company to prepay up to $3.5 million of the subordinated convertible notes issued in connection with the Company’s acquisition of Compass in 2011. On March 9, 2016, the Company amended the 2013 Credit Agreement. The amendment increases the revolving line of credit commitment by $15 million to a total of $40 million and allows the Company to maintain our maximum consolidated total leverage ratio at 3.00 to 1.00 through the first quarter of 2017. The material terms of the senior secured credit facility under the 2013 Credit Agreement are as follows: · The credit facility is secured by all of the equity interests owned by the Company, and its direct and indirect domestic subsidiaries and, subject to agreed exceptions, the Company’s direct and indirect “first ‑tier” foreign subsidiaries and a perfected first priority security interest in all of the Company’s direct and indirect domestic subsidiaries’ tangible and intangible assets. · The Company’s direct and indirect existing and future wholly ‑owned domestic subsidiaries serve as guarantors to the Company’s obligations under the senior secured facility. · Mandatory repayments of term loans shall be required from (subject to agreed exceptions) (i) 100% of the proceeds from asset sales by the Company and its subsidiaries, (ii) 100% of the net proceeds from issuances of debt and equity by the Company and its subsidiaries, and (iii) 100% of the net proceeds from insurance recovery and condemnation events of the Company and its subsidiaries. · The senior secured credit facility contains a number of covenants that, among other things, place restrictions on matters customarily restricted in senior secured credit facilities, including restrictions on indebtedness (including guarantee obligations), liens, fundamental changes, sales or disposition of property or assets, investments (including loans, advances, guarantees and acquisitions), transaction with affiliates, dividends and other payments in respect of capital stock, optional payments and modifications of other material debt instruments, negative pledges and agreements restricting subsidiary distributions and changes in line of business. In addition, the Company is required to comply with a total leverage ratio and fixed charge coverage ratio. As of December 31, 2015, our maximum total leverage ratio was 3.00 to 1.00 and we were in compliance with all covenants contained in the 2013 Credit Agreement. · The senior secured credit facility contains customary events of default, including cross ‑default to other material agreements, judgment default and change of control. We are required under the 2013 Credit Agreement to establish a fixed or maximum interest rate covering a notional amount of not less than 50% of the aggregate outstanding indebtedness for borrowed money (other than the total revolving outstanding) for a period of three years from the closing date of our 2013 Credit Agreement. Subsequent to May 3, 2013, we entered into an agreement to cap the interest rate at 5% on the LIBOR component of our borrowings under the term loan facility until May 3, 2016. This interest rate cap is not designated for hedging or speculative purposes. The expense related to this interest rate cap was nominal. As of December 31, 2015, the total principal outstanding under the term loan facility and revolving credit facility was $37.4 million and $10.0 million, respectively. Additional mandatory principal repayments totaling $ 2.3 million will be due in each of 2016 and 2017 . Compass Convertible Notes On January 4, 2011, as part of the consideration for the acquisition of Compass, we issued an aggregate of $6.3 million in convertible notes to Compass (the “Notes”). The Notes mature on January 4, 2018 and interest is payable on the outstanding principal amount, computed daily, at the rate of 3.875% per annum on January 31 of each calendar year and on the seventh anniversary of the date of the Notes. The Notes were subject to transfer restrictions until January 31, 2013. If the price of our common stock on the Nasdaq Global Market exceeds $4 per share for 60 consecutive trading days (the “Trigger Event”), the holder of the Notes may convert all (but not less than all) of the outstanding principal amount of the Notes into shares of our common stock at the rate of 1 share for every $4 in principal amount outstanding. After the Trigger Event, we may prepay all or any portion of the outstanding principal amount of the Notes by giving the holder 30 days written notice. On April 26, 2013, the Company settled a portion of the Notes. The payee agreed to accept from the Company an amount equal to $650,000 as satisfaction in full of all indebtedness of $1.1 million owing by the Company to such payee. As a result of this transaction, the Company recognized a gain of $0.5 million in the second quarter of 2013 representing the difference between the fair value of the consideration issued in the settlement transaction and the carrying value of the amounts due to the payee. This amount was recorded in Gain on Extinguishment of Debt in the accompanying consolidated statement of comprehensive income (loss). On November 14, 2013, our lenders agreed to amend the 2013 Credit Agreement to allow the Company to prepay the entire outstanding principal amount of the CPIV S.A. Convertible Note (“CPIV Note”) plus accrued interest and exclude the CPIV Note prepayment from the calculation of our consolidated fixed charge coverage ratio. On November 25, 2013, the Company prepaid the CPIV Note and the payee agreed to accept from the Company an amount equal to the principal of $1.7 million plus accrued interest as satisfaction in full of all indebtedness owing by the Company to such payee. Therefore, there was no gain or loss recorded as a result of this transaction. On March 21, 2014, the Trigger Event occurred. As a result, a holder of the Notes may convert all (but not less than all) of the outstanding principal amount of the Notes into shares of our common stock at the rate of 1 share for every $4 in principal amount outstanding. In addition, ISG may elect to prepay all or any portion of the outstanding principal amount of the Notes by giving a holder 30 days written notice; however, such holder shall be given the opportunity to convert the outstanding principal amount into shares as described above. No holder of the Notes has the option to require cash payment as a result of the Trigger Event, hence the Notes are classified as non-current.

For the years ended December 31, 2015, 2014 and 2013, $1.5 million, $1.6 million and $1.6 million were contributed to the Plan by the Company, respectively. Leases The Company leases its office space under long ‑term operating lease agreements which expire at various dates through August 2021. Under the operating leases, the Company pays certain operating expenses relating to the leased property and monthly base rent. Aggregate future minimum payments under noncancelable leases with initial or remaining terms of one year or more consist of the following at December 31, 2015: Operating Leases 2016 $ 2017 2018 2019 2020 Thereafter Total minimum lease payments $ The Company’s rental expense for operating leases was $2.9 million, $3.6 million and $3.2 million, in 2015, 2014 and 2013, respectively. STA Consulting Contingent Consideration The Company expects to pay the remaining contingent liability of $1.7 in the first quarter of 2016 related to 2015 performance.

An associated tax indemnity receivable was also reversed and recorded in selling, general and administrative expenses. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and liabilities were as follows: December 31, December 31, 2015 2014 Current deferred tax asset Compensation related expenses $ $ Valuation allowance for deferred tax assets Accruals and reserves Total current deferred tax asset Current deferred tax liability Prepaids Total current deferred tax liability Net current deferred tax asset $ $ Noncurrent deferred tax asset Compensation related expenses $ $ Foreign currency translation Foreign tax credit carryovers Foreign net operating loss carryovers U.S. net operating loss carryovers Other Valuation allowance for deferred tax assets Total noncurrent deferred tax asset Noncurrent deferred tax liability Depreciable assets Intangible assets Investment in foreign subsidiaries Total noncurrent deferred tax liability Net noncurrent deferred tax asset Net deferred tax asset $ $ A valuation allowance was established at December 31, 2015 and 2014 due to estimates of future utilization of net operating loss carryovers in the U.S. and certain foreign jurisdictions, derived primarily from acquisitions and recorded through purchase accounting. The valuation allowance at December 31, 2015 and 2014 primarily includes a full valuation for the Company’s foreign tax credit carryovers and foreign taxes on its controlled foreign corporation. Uncertain tax positions Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more ‑likely ‑than ‑not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more ‑likely ‑than ‑not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more ‑likely ‑than ‑not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. It is the Company’s policy to accrue for interest and penalties related to its uncertain tax positions within income tax expense. A tabular reconciliation of the total amounts of unrecognized tax benefits at the beginning and end of the period is as follows: December 31, 2015 2014 2013 Balance, beginning of year $ $ $ Reductions as a result of tax positions taken during a prior period — — Additions as a result of tax positions taken during the current period Additions as a result of tax positions taken during a prior period — — Reductions as a result of settlement with tax authorities — — Reductions as a result of lapse of statute Balance, end of year $ $ $ We do not expect our unrecognized tax benefits to significantly change in the next twelve months. The Company has recognized through income tax expense approximately $0.5 million of interest and penalties related to uncertain tax positions. The amount of unrecognized tax benefit, if recognized, that would impact the effective tax rate is $1.8 million. With few exceptions, the Company is no longer subject to U.S. federal, state, local, or non ‑U.S. income tax examinations by tax authorities for years before 2009.

STOCK BASED COMPENSATION PLANS
STOCK BASED COMPENSATION PLANS	NOTE 16—STOCK ‑BASED COMPENSATION PLANS The Amended and Restated 2007 Equity and Incentive Award Plan (“Incentive Plan”) and Amended and Restated 2007 Employee Stock Purchase Plan (“ESPP”) were approved by the Company’s stockholders. Subject to the term s of the Incentive Plan, the Incentive Plan authorizes the grant of awards, which awards may be made in the form of (i) nonqualified stock options; (ii) stock options intended to qualify as incentive stock options under Section 422 of the Internal Revenue Code (stock options described in clause (i) and (ii), “options”); (iii) stock appreciation rights (“SARs”); (iv) restricted stock and/or restricted stock units; (v) other stock based awards ; (vi) performance-based awards, which are equity awards or incentive awards intended to qualify for full tax deductibility by the company under Code Section 162 (m) ; and (vii) incentive awards, a cash-denominated award earnable by achievement of performance goals. The issuance of shares or the payment of cash upon the exercise of an award or in consideration of the cancellation or termination of an award shall reduce the total number of shares available under the equity incentive plan, as applicable. The provisions of each award will vary based on the type of award granted and will be specified by the Compensation Committee of the Board of Directors. Those awards which are based on a specific contractual term will be granted with a term not to exceed ten years. The SARs granted under the Incentive Plan are granted with an exercise price equal to the fair market value of the Common Shares at the time the SARs are granted. As of December 31, 2015, there were 3,388,143 and 1,027,086 shares available for grant under the amended and restated Incentive Plan and ESPP, respectively. The Company recognized $5.0 million, $3.1 million and $3.4 million in employee stock ‑based compensation expense during the years ended December 31, 2015, 2014 and 2013, respectively. This expense was recorded in selling, general and administrative in the consolidated statement of comprehensive income. Restricted Share Awards/Units The Incentive Plan provides for the granting of restricted share awards (“RSA”) or restricted share units (“RSU”), the vesting of which is subject to conditions and limitations established at the time of the grant. Upon the grant of an RSA, the participant has the rights of a shareholder, including but not limited to the right to vote such shares and the right to receive any dividends paid on such shares. Recipients of RSU awards will not have the rights of a shareholder of the Company until such date as the Common Shares are issued or transferred to the recipient. If the employee retires (at the normal retirement age stated in the applicable retirement plan or applicable law, if there is a mandatory retirement age), the restricted shares continue to vest on the same schedule as if the employee remained employed with the Company. Upon a change in control, or upon a termination of employment due to employee’s death or permanent disability, the restricted shares become 100% vested. Dividends accrue and will be paid if and when the restricted shares vest. The Company also granted RSUs to specific employees which have the following characteristics: · Performance ‑Based RSU Vesting (EBITDA): Provided the employee continues to be employed through specific date set forth in the award, the RSUs will vest on such date if specific financial performance is met, otherwise the RSUs will be forfeited. · Time ‑Based RSU Vesting: So long as the employee continues to be employed through the fourth anniversary of the grant date, the RSUs will become 100% vested on such date. If an employee’s employment is terminated (i) at any time during the vesting period due to the employee’s death, disability or retirement prior to the applicable vesting date or (ii) without cause by the Company after 50% of the relevant period has elapsed, then the RSUs will vest prorata based on the period of time worked relative to such period. However, no shares will be distributed until the applicable pro rata vesting date (and, in the case of the Performance ‑Based RSUs, only if and to the extent that the performance target is achieved). In all other terminations occurring prior to the applicable vesting date, the RSUs will expire. Pursuant to the terms of the Incentive Plan, in the event of a change in control, the Compensation Committee of the Board of Directors may accelerate vesting of the outstanding awards of RSUs then held by participants. All RSUs will be payable in shares of the Company’s common stock immediately upon vesting. No dividend equivalents will be paid with respect to any RSUs. The fair value of RSAs and RSUs is determined based on the closing price of the Company’s shares on the grant date. The total fair value is amortized to expense on a straight ‑line basis over the vesting period. There has been no activities for RSAs since December 31, 2011. A summary of the status of the Company’s RSUs issued under its Incentive Plan as of December 31, 2015 and changes during the year then ended, is presented below: Weighted- Average Grant Date RSU Fair Value Non-vested at December 31, 2012 $ Granted $ Vested $ Forfeited $ Non-vested at December 31, 2013 $ Granted $ Vested $ Forfeited $ Non-vested at December 31, 2014 $ Granted $ Vested $ Forfeited $ Non-vested at December 31, 2015 $ The total fair value of RSUs vested during the years ended December 31, 2015, 2014 and 2013 was $3.6 million $1.4 million and $3.8 million, respectively. As of December 31, 2015, there was $7.4 million of unrecognized compensation cost related to RSUs, which is expected to be recognized over a weighted ‑average period of 2.3 years. Stock Appreciation Rights The Compensation Committee may grant (i) a stock appreciation right independent of an option or (ii) a stock appreciation right in connection with an option, or a portion thereof. A stock appreciation right granted pursuant to clause (ii) of the preceding sentence (A) may be granted at the time the related option is granted or at any time prior to the exercise or cancellation of the related option, (B) shall cover the same number of shares covered by an option (or such lesser number of shares as the Compensation Committee may determine) and (C) shall be subject to the same terms and conditions as such option except for such additional limitations as are contemplated above (or such additional limitations as may be included in an award agreement). SARs granted pursuant to the Incentive Plan are granted with an exercise price equal to the fair market value of the Common Shares at the time the SARs are granted. Pursuant to the applicable award agreements, the SARs vest and become exercisable with respect to 25% of the shares subject to the SARs on the first four anniversaries of the grant date, so long as the employee remains employed with the Company on each such date. If the employee’s employment with the Company is terminated as a result of the employee’s death or disability, all unvested SARs will be fully vested. If the employee retires, the SARs will continue to vest on the same schedule as if the employee had remained employed with the Company. Any vested SARs will expire upon the earliest to occur of the following: (i) the tenth anniversary of the grant date; (ii) one year following the date of the employee’s termination of services as a result of death or permanent disability; (iii) 90 days following the fourth anniversary of the grant date, following the participant’s retirement; (iv) 30 days following the date of the participant’s termination of employment for any reason (other than as a result of death, disability or retirement); and (v) immediately upon a termination for cause. SARs will be settled in the form of shares of the Company’s common stock upon exercise. A summary of the status of the Company’s SARs issued under its Incentive Plan is presented below: Weighted-Average Weighted-Average Remaining Aggregate Exercise Contractual Intrinsic SARs Price Life Value (in years) Outstanding at December 31, 2012 $ $ — Granted — $ — Exercised $ $ Forfeited $ Outstanding at December 31, 2013 $ $ Granted — $ — Exercised $ $ Forfeited $ $ Outstanding at December 31, 2014 $ $ Granted — $ — Exercised $ $ Forfeited $ $ — Outstanding at December 31, 2015 $ $ Vested and expected to vest at December 31, 2015 $ $ Exercisable at December 31, 2015 $ $ The Company did not grant any SAR during the years end December 31, 2015, 2014 and 2013, respectively. The total fair value of the SARs vested during the years ended December 31, 2015, 2014 and 2013 was $0 , $0 and $6,000 , respectively. As of December 31, 2015, all of the compensation costs related to the Company’s vested SARs have been recognized. Employee Stock Purchase Plan The Company uses the Black ‑Scholes option pricing model to estimate the fair value of shares expected to be issued under the Company’s employee stock purchase plan. The ESPP provides that a total of 1.2 million shares of Common Stock are reserved for issuance under the plan. The ESPP, which is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code, is implemented utilizing three -month offerings with purchases occurring at three -month intervals. The ESPP administration is overseen by the Company’s Compensation Committee. Employees are eligible to participate if they are employed by the Company for at least 20 hours per week and more than five months in a calendar year. The ESPP permits eligible employees to purchase Common Stock through payroll deductions, ranging from one to ten percent of their eligible earnings subject to IRS regulated cap of $25,000 . The price of Common Stock purchased under the ESPP is 90% of the fair market value of the Common Stock on the applicable purchase date. Employees may end their participation in an offering at any time during the offering period, and participation ends automatically upon termination of employment. The Compensation Committee may at any time amend or terminate the ESPP, except that no such amendment or termination may adversely affect shares previously granted under the ESPP. The Company may issue new shares for the ESPP using treasury shares or newly issued shares. For the year ended December 31, 2015, the Company issued 159,335 shares for the ESPP. There were 1,027,086 shares available for purchase at December 31, 2015 under the ESPP.

SUBSEQUENT EVENT.
SUBSEQUENT EVENT	NOTE 19 —S UBSEQUENT EVENT On March 9, 2016, the Company’s Board of Directors approved a new share repurchase authorization of up to $15 million. The new share repurchase program will take effect upon completion of the Company’s current program, which has approximately $14.7 million remaining . The repurchase program is expected to be executed over time. The shares may be repurchased from time to time in open market transactions at prevailing market prices, in privately negotiated transactions, pursuant to a Rule 10b5-1 repurchase plan or by other means in accordance with federal securities laws. The timing and the amount of any repurchases will be determined by the Company’s management based on its evaluation of market conditions, capital allocation alternatives, and other factors. There is no guarantee as to the number of shares that will be repurchased, and the repurchase program may be extended, suspended or discontinued at any time without notice at the Company's discretion . On March 10, 2016 the Compa ny commenced a tender offer to p urchase up to $12.0 million in value of shares of its common stock $0.001 par value per share (“the “Shares”), a t a price not greater than $ 4.00 nor less than $ 3.30 per Share, to the seller in cash, less any applicable withholding taxes and without interest (“the “Offer”). The Offer is scheduled to expire on April 7, 2016. The Company is conducting the Offer through a procedure co mmonly called a modified “Dutch A uction”. This procedure allows stockholders to select the price, within the specified range, as which stockholders are willing to sell their shares. The Company will select the single lowest purchase price, not great than the $ 4.00 nor less than $ 3.30 per Share, that will allow the Company to purchase up to $12.0 million in value of Shares at such price, based on the number of Shared tendered, or, if fewer Shares are properly tendered, all Shares that are properly tendered and not properly withdrawn.

SUMMARY OF SIGNIFICANT ACCOUN28

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2015
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly ‑owned subsidiaries. These consolidated financial statements and footnotes are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, references to the Company include ISG and its consolidated subsidiaries.
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 the disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates. The complexity of the estimation process and issues related to the assumptions, risks and uncertainties inherent in the application of the proportional performance method of accounting affect the amounts of revenues, expenses, unbilled receivables and deferred revenue. Numerous internal and external factors can affect estimates. Estimates are also used for but not limited to: allowance for doubtful accounts, useful lives of furniture, fixtures and equipment and definite ‑lived intangible assets, depreciation expense, fair value assumptions in analyzing goodwill and intangible asset impairments, income taxes and deferred tax asset valuation, and the valuation of stock based compensation.
Business Combinations	Business Combinations We have acquired businesses critical to the Company’s long ‑term growth strategy. Results of operations for acquisitions are included in the accompanying consolidated statement of comprehensive income from the date of acquisition. Acquisitions are accounted for using the purchase method of accounting and the purchase price is allocated to the net assets acquired based upon their estimated fair values at the date of acquisition. The excess of the purchase price over the net assets was recorded as goodwill. Acquisition-related costs are expensed as incurred and recorded in selling, general and administrative expenses. Final valuations of assets and liabilities are obtained and recorded within one year from the date of the acquisition.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents, including certain money market accounts. The Company principally maintains its cash in money market and bank deposit accounts in the United States of America which typically exceed applicable insurance limits. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists of cash and cash equivalents which the Company has pledged to fulfill certain obligations and are not available for general corporate purposes.
Accounts and Unbilled Receivables and Allowance for Doubtful Accounts	Accounts and Unbilled Receivables and Allowance for Doubtful Accounts Our trade receivables primarily consist of amounts due for services already performed via fixed fee or time and materials arrangements. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of clients to pay fees or for disputes that affect its ability to fully collect billed accounts receivable. The allowance for these risks is prepared by reviewing the status of all accounts and recording reserves on a specific identification method based on previous experiences and historical bad debts. However, our actual experience may vary significantly from these estimates. If the financial condition of our clients were to deteriorate, resulting in their inability or unwillingness to pay their invoices, we may need to record additional allowances or write ‑offs in future periods. To the extent the provision relates to a client’s inability or unwillingness to make required payments, the provision is recorded as bad debt expense, which is classified within selling, general and administrative expense in the accompanying consolidated statement of comprehensive income. The provision for unbilled services is recorded as a reduction to revenues to the extent the provision relates to fee adjustments and other discretionary pricing adjustments.
Prepaid Expenses and Other Assets	Prepaid Expenses and Other Assets Prepaid expenses and other assets consist primarily of prepaid expenses for insurance, conferences and deposits for facilities, programs and promotion items.
Furniture, Fixtures and Equipment, net	Furniture, Fixtures and Equipment, net Furniture, fixtures and equipment is recorded at cost. Depreciation is computed by applying the straight ‑line method over the estimated useful life of the assets, which ranges from three to five years. Leasehold improvements are depreciated over the lesser of the useful life of the underlying asset or the lease term, which generally range from three to five years. Expenditures for renewals and betterments are capitalized. Repairs and maintenance are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and any associated gain or loss thereon is reflected in the accompanying consolidated statement of comprehensive income.
Internal-Use Software and Website Development Costs	Internal ‑Use Software and Website Development Costs The Company capitalizes internal ‑use software and website development costs and records these amounts within furniture, fixtures and equipment. Accounting standards require that certain costs related to the development or purchase of internal ‑use software and systems as well as the costs incurred in the application development stage related to its website be capitalized and amortized over the estimated useful life of the software or system. They also require that costs related to the preliminary project stage, data conversion and post implementation/operation stage of an internal ‑use software development project be expensed as incurred. During the years ended December 31, 2015, 2014 and 2013, the Company capitalized $0.3 million, $0.6 million and $0.7 million, respectively, of costs associated with the system conversion and website development.
Goodwill	Goodwill Our goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets acquired at the date of acquisition. Goodwill is not amortized but rather tested for impairment at least annually by applying a fair ‑value based test in accordance with accounting and disclosure requirements for goodwill and other indefinite ‑lived intangible assets. This test is performed by us during our fourth fiscal quarter or more frequently if we believe impairment indicators are present. We performed step one of a two ‑step impairment test on goodwill. Step one compares the fair value of the reporting unit to its carrying amount, including goodwill. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then we must perform the second step of the impairment test whereby the carrying value of the reporting unit’s goodwill is compared to its implied fair value. If the carrying value of the goodwill exceeds the implied fair value, an impairment loss equal to the difference is recorded. In performing the first step of the impairment test on goodwill, we determined the fair value of the reporting unit using both a market and income approach. The income approach utilizes a discounted cash flow model and is based on projections of future operations of the reporting unit as of the valuation date. The market approach is based on our stock price and provides a direct indication of fair value. Under the market approach, we determined the fair value of the reporting unit utilizing a relevant average of our common stock price for the October 31 measurement period, as quoted on the Nasdaq Global Market plus a 35% control premium based upon recent transactions of comparable companies. The discounted cash flow model assumed revenue growth rates of approximately 3% per year. We employed a discount rate of 13.5% to discount future excess cash flows. As a result of the step one test performed, the fair value of our reporting substantially unit exceeded the carrying value. Therefore, step two was not performed or required.
Long-Lived Assets	Long ‑Lived Assets Long ‑lived assets, excluding goodwill and indefinite ‑lived intangibles, to be held and used by the Company are reviewed to determine whether any significant change in the long ‑lived asset’s physical condition, a change in industry conditions or a reduction in cash flows associated with the use of the long ‑lived asset. If these or other factors indicate the carrying amount of the asset may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset. The fair value of the asset is measured using market prices or, in the absence of market prices, an estimate of discounted cash flows. Cash flows are generally discounted at an interest rate commensurate with our weighted average cost of capital for a similar asset. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria of accounting and disclosure requirement for the impairment or disposal of long ‑lived assets.
Debt Issuance Costs	Debt Issuance Costs Costs directly incurred in obtaining long ‑term financing, typically bank and attorney fees, are deferred and are amortized over the life of the related loan using the effective interest method. Deferred issuance costs are classified as other assets in the accompanying consolidated balance sheet. Amortization of debt issuance costs is included in interest expense and totaled $ 0.1 million, $0.2 million and $0.2 million for the years ended December 31, 2015, 2014 and 2013, respectively.
Revenue Recognition	Revenue Recognition We recognize our revenues for the sale of services and products when persuasive evidence of an arrangement exists, services have been rendered or delivery has occurred, the fee is fixed or determinable and the collectability of the related revenue is reasonably assured. We principally derive revenues from fees for services generated on a project ‑by ‑project basis. Prior to the commencement of a project, we reach agreement with the client on rates for services based upon the scope of the project, staffing requirements and the level of client involvement. It is our policy to obtain written agreements from new clients prior to performing services. In these agreements, the clients acknowledge that they will pay based upon the amount of time spent on the project or an agreed upon fee structure. Revenues for services rendered are recognized on a time and materials basis or on a fixed ‑fee or capped ‑fee basis in accordance with accounting and disclosure requirements for revenue recognition. Fees for services that have been performed, but for which we have not invoiced the customers are recorded as unbilled receivables in the accompanying consolidated balance sheets. Revenues from subscription contracts are recognized ratably over the life of the contract, which is generally one year. These fees are typically billed in advance and included in deferred revenue until recognized. Revenues for time and materials contracts are recognized based on the number of hours worked by our advisors at an agreed upon rate per hour and are recognized in the period in which services are performed. Revenues for time and materials contracts are billed monthly, semimonthly or in accordance with the specific contractual terms of each project. Revenues related to fixed ‑fee or capped ‑fee contracts are recognized into revenue as value is delivered to the customer. The pattern of revenue recognition for these contracts varies depending on the terms of the individual contracts, and may be recognized proportionally over the term of the contract or deferred until the end of the contract term and recognized when our obligations have been fulfilled with the customer. In instances where substantive acceptance provisions are specified in customer contracts, revenues are deferred until all acceptance criteria have been met. The pattern of revenue recognition for contracts where revenues are recognized proportionally over the term of the contact is based on the proportional performance method of accounting using the ratio of labor hours incurred to estimated total labor hours, which we consider to be the best available indicator of the pattern and timing in which contract obligations are fulfilled. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. The contracted amount used in this calculation typically excludes the amount the client pays for reimbursable expenses. There are situations where the number of hours to complete projects may exceed our original estimate as a result of an increase in project scope or unforeseen events. On a regular basis, we review the hours incurred and estimated total labor hours to complete. The results of any revisions in these estimates are reflected in the period in which they become known. We believe we have demonstrated a history of successfully estimating the total labor hours to complete a project. The agreements entered into in connection with a project, whether on a time and materials basis or fixed ‑fee or capped ‑fee basis, typically allow our clients to terminate early due to breach or for convenience with 30 days’ notice. In the event of termination, the client is contractually required to pay for all time, materials and expenses incurred by us through the effective date of the termination. In addition, from time to time, we enter into agreements with clients that limit our right to enter into business relationships with specific competitors of that client for a specific time period. These provisions typically prohibit us from performing a defined range of services that it might otherwise be willing to perform for potential clients. These provisions are generally limited to six to twelve months and usually apply only to specific employees or the specific project team.
Reimbursable Expenditures	Reimbursable Expenditures Amounts billed to customers for reimbursable expenditures are included in revenues and the associated costs incurred by the Company are included in direct costs and expenses for advisors in the accompanying consolidated statement of comprehensive income. Non ‑reimbursable amounts are expensed as incurred. Reimbursable expenditures totaled $10.1 million, $9.9 million and $10.4 million for the years ended December 31, 2015, 2014 and 2013, respectively.
Direct Costs and Expenses for Advisors	Direct Costs and Expenses for Advisors Direct costs and expenses for advisors include payroll expenses and advisory fees directly associated with the generation of revenues and other program expenses. Direct costs and expenses for advisors are expensed as incurred. Direct costs and expenses for advisors also include expense accruals for discretionary bonus payments. Bonus accrual levels are adjusted throughout the year based on actual and projected individual and Company performance.
Stock-Based Compensation	Stock ‑Based Compensation We grant restricted stock with a fair value that is determined based on the closing price of our common stock on the date of grant. Restricted stock generally vests over a four -year period for employees and a three -year period for directors. Stock ‑based compensation expense is recognized ratably over the applicable service period. We follow the provisions of accounting and disclosures requirement for share-based payments, requiring the measurement and recognition of all share ‑based compensation under the fair value method.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and accounts receivable. The Company places its cash investments with high quality financial institutions. The Company extends credit to its customers based upon an evaluation of the customer’s financial condition and credit history and generally does not require collateral.
Treasury Stock	Treasury Stock The Company makes treasury stock purchases in the open market pursuant to the share repurchase program, which was approved by the Board of Directors on May 6, 2014. Treasury stock is recorded on the consolidated balance sheet at cost as a reduction of stockholders’ equity. Shares are released from Treasury at original cost on a first ‑in, first ‑out basis, with any gain on the sale reflected as an adjustment to additional paid ‑in capital. Losses are reflected as an adjustment to additional paid ‑in capital to the extent of gains previously recognized, otherwise as an adjustment to retained earnings.
Foreign Currency Translation	Foreign Currency Translation The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the end of the reporting period. Revenue and expense items are translated at average exchange rates for the reporting period. Resulting translation adjustments are included in the accompanying statement of comprehensive income and accompanying statement of stockholders’ equity as a component of Accumulated Other Comprehensive Loss . The functional currency of the Company and its subsidiaries is the respective local currency. The Company has contracts denominated in foreign currencies and therefore, a portion of the Company’s revenues are subject to foreign currency risks. Transactional currency gains and losses that arise from transactions denominated in currencies other than the functional currencies of our operations are recorded in Foreign Currency Transaction Loss in the accompanying consolidated statement of comprehensive income.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying value of the Company’s cash and cash equivalents, receivables, accounts payable, other current liabilities, and accrued interest approximate fair value. Fair value measurements were applied with respect to our nonfinancial assets and liabilities measured on a nonrecurring basis, which would consist of measurements primarily to goodwill, intangible assets and other long ‑lived assets, and assets acquired and liabilities assumed in a business combination. Fair value is the price that would be received upon a sale of an asset or paid upon a transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). Market participants can use market data or assumptions in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market ‑corroborated, or generally unobservable. The use of unobservable inputs is intended to allow for fair value determinations in situations where there is little, if any, market activity for the asset or liability at the measurement date. Under the fair ‑value hierarchy: · Level 1 measurements include unadjusted quoted market prices for identical assets or liabilities in an active market; · Level 2 measurements include quoted market prices for identical assets or liabilities in an active market that have been adjusted for items such as effects of restrictions for transferability and those that are not quoted but are observable through corroboration with observable market data, including quoted market prices for similar assets; and · Level 3 measurements include those that are unobservable and of a highly subjective measure. During 2015, there were no transfers of our financial assets between Level 1 and Level 2 measures. Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables summarize assets and liabilities measured at fair value on a recurring basis at the dates indicated: Basis of Fair Value Measurements 12/31/2015 Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ $ — $ — $ Total $ $ — $ — $ Liabilities: Contingent consideration (1) $ — $ — $ $ Long-term debt, including current portion — — $ — $ — $ $ Basis of Fair Value Measurements 12/31/2014 Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ $ — $ — $ Total $ $ — $ — $ Liabilities: Contingent consideration (1) $ — $ — $ $ Long-term debt, including current portion — — $ — $ — $ $ (1) The short-term portion is included in “accrued expenses.” The long-term portion is included in “Other liabilities.” The fair value measurement of this contingent consideration is classified within Level 3 of the fair value hierarchy and reflects the Company’s own assumptions in measuring fair values using the income approach. In developing these estimates, the Company considered certain performance projections, historical results, and industry trends. This amount was estimated through a valuation model that incorporated probability-weighted assumptions related to the achievement of these milestones and the likelihood of the Company making payments. These cash outflow projections have then been discounted using a rate ranging from 2.3% to 14.5% . The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair values of debt have been estimated using a discounted cash flow analysis based on the Company's incremental borrowing rate for similar borrowing arrangements. The incremental borrowing rate used to discount future cash flows ranged from 2.46% to 2.74% . The Company also considered recent transactions of peer group companies for similar instruments with comparable terms and maturities as well as an analysis of current market conditions. The following table represents the change in the contingent consideration liability during the years ended December 31, 2015 and 2014: December 31, 2015 2014 Beginning Balance $ $ Payment of contingent consideration Acquisition Change in fair value of contingent consideration Accretion of contingent consideration Unrealized loss related to currency translation Ending Balance $ $
Dividend	Dividend On December 2, 2014 the Board of Directors authorized a special dividend of $0.14 per share on the Company’s issued and outstanding shares of common stock. This cash dividend of $5.2 million was paid on January 28, 2015 to shareholders of record as of January 15, 2015. Prior to this special dividend we had not paid any dividends on our common stock.
Income Taxes	Income Taxes We use the asset and liability method to account for income taxes, including recognition of deferred tax assets and liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax basis. We review our deferred tax assets for recovery. A valuation allowance is established when we believe that it is more likely than not that some portion of its deferred tax assets will not be realized. Changes in the valuation allowance from period to period are included in our tax provision in the period of change. For uncertain tax positions, we use a prescribed model for assessing the financial recognition and measurement of all tax positions taken or expected to be taken in its tax returns. The guidance provides clarification on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition. Our provision for income taxes also includes the impact of provisions established for uncertain income tax positions, as well as the related interest.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance that outlines a single comprehensive model for entities to use in accounting for revenue. Under the guidance, revenue is recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard is effective for public entities with annual and interim reporting periods beginning after December 15, 2016. On July 9, 2015, the FASB approved the deferral of the effective date of the new revenue guidance by one year to annual reporting periods beginning after December 15, 2017, with early adoption being permitted for annual periods beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt the guidance. We are currently assessing the effects this guidance may have on our consolidated financial statements, as well as the method of transition that we will use in adopting the new standard. In April 2015, the FASB issued guidance require the presentation of debt issuance costs in financial statements as a direct reduction of related debt liabilities with amortization of debt issuance costs reported as interest expense. Under current U.S. GAAP standards, debt issuance costs are reported as deferred charges (i.e., as an asset). In August 2015, the FASB clarified the guidance that debt issuance costs related to line-of-credit arrangements could continue to be presented as an asset and be subsequently amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the arrangement. This guidance is effective for annual periods, and interim periods within those fiscal years, beginning after December 15, 2015 and is to be applied retrospectively upon adoption. Early adoption is permitted, including adoption in an interim period for financial statements that have not been previously issued. At December 31, 2015, the Company had debt issuance costs of $0.6 million. In September 2015, the FASB issued updated guidance, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Acquirers must recognize measurement-period adjustments during the period of resolution, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The updated guidance is effective for fiscal years beginning after December 15, 2015. Earlier adoption is permitted for any interim and annual financial statements that have not yet been issued. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In November 2015, the FASB issued an accounting standards update to simplify the presentation of deferred income taxes on the balance sheet. The update requires that all deferred tax assets and liabilities be classified as noncurrent. The current guidance that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not impacted by this update. The provisions of the new standard are effective beginning January 1, 2017, for annual and interim periods and early adoption is permitted. We do not expect the adoption of this guidance to have a material impact on our results of operations, but will result in a reclassification of current net deferred tax on our balance sheet in future years. Adoption of the guidance as of December 31, 2015 would result in a reclassification of current net deferred tax of $2.1 million and $1.1 million as of December 31, 2015 and 2014, respectively.
