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 revenue recognition guidance for contracts in which control is transferred to the customer over time affect the amounts of revenues, expenses, contract assets and contract liabilities. 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 evaluating goodwill for impairment, 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 is recorded as goodwill. Acquisition-related costs are expensed as incurred and recorded in selling, general and administrative expenses. ​ 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 committed for rent deposits and are not available for general corporate purposes. ​ Accounts Receivable, Contract Assets and Allowance for Doubtful Accounts Our trade receivables primarily consist of amounts due for services already performed. 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 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. Historically, the Company’s bad debt reserves and write-offs have not been significant. ​ 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. Historically, the Company’s unbilled receivable reserves and write-offs have not been significant. ​ Prepaid Expenses and Other Current Assets ​ Prepaid expenses and other current assets consist primarily of prepaid expenses for insurance, conferences, deposits for facilities, programs, software and promotion items. ​ Furniture, Fixtures and Equipment, net ​ Furniture, fixtures and equipment are recorded at cost. Depreciation is computed by applying the straight-line method over the estimated useful life of the assets, which ranges from two two The Company capitalizes internal-use software and website development costs and records these amounts within Furniture, Fixtures and Equipment, net. 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, 2022 and 2021, the Company capitalized $1.7 million and $0.8 million, respectively, of costs associated with system 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 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. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value of the reporting unit is less than its carrying amount. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value then goodwill is tested further for impairment. If the fair value of goodwill is lower than its carrying amount, an impairment loss is recognized in an amount equal to the difference. Subsequent increases in value are not recognized in the financial statements. There was no impairment of goodwill during the years ended December 31, 2022 and 2021, nor were any indicators identified in 2022 or 2021 that would suggest that it is more likely than not that the Company’s reporting unit is impaired. 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 asset group that contains the long-lived asset. If these or other factors indicate the carrying amount of the asset group, which is the lowest level for which identifiable cash flows exist that are separately identifiable from other cash flows, may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset group. The fair value of the asset group 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. 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. ​ 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. Deferred issuance costs are classified as a direct deduction to the long-term debt in the accompanying consolidated balance sheet. Amortization of debt issuance costs is included in interest expense and totaled $0.3 million and $0.4 million for the years ended December 31, 2022 and 2021, respectively. Revenue Recognition premise software, hybrid and software-as-a-service licenses, as well as other software-related services. Revenue associated with the software performance obligation is primarily recognized at the point at which the software is installed or access is granted. 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 $0.8 million and $0.3 million for the years ended December 31, 2022 and 2021, respectively. The increase was attributable to pandemic-related travel restrictions being lifted in 2022. ​ 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 Company performance. ​ Stock-Based Compensation We grant restricted stock units with a fair value that is determined based on the closing price of our common stock on the date of grant. Such grants generally vest ratably over a two four - We follow the provisions of accounting and disclosure requirements for share-based payments, including 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 most recently approved by the Board of Directors on August 5, 2021. ​ 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 or loss on the sale reflected as an adjustment to additional paid-in capital. ​ 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 Translation ​ 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 2022, there were no transfers of our financial assets between Level 1, Level 3 fair value ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basis of Fair Value Measurements ​ ​ December 31, 2022 ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ Total ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents $ 18 $ — $ — $ 18 ​ Total $ 18 $ — $ — $ 18 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration (1) $ — $ — $ 5,593 $ 5,593 ​ ​ $ — $ — $ 5,593 $ 5,593 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basis of Fair Value Measurements ​ ​ December 31, 2021 ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ Total ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents $ 1,018 $ — $ — $ 1,018 ​ Total $ 1,018 $ — $ — $ 1,018 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration (2) $ — $ — $ 2,420 $ 2,420 ​ ​ $ — $ — $ 2,420 $ 2,420 ​ (1) The current and noncurrent contingent consideration are included in “Accrued expenses and other current liabilities” and “Other liabilities,” respectively, as of December 31, 2022.

The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company’s outstanding borrowings was approximately $76.5 million and $73.6 million at December 31, 2022 and December 31, 2021, respectively. The fair values of debt have been estimated using a discounted cash flow Income Taxes Recently Issued Accounting Pronouncements In June 2016, the FASB issued new guidance on the measurement of credit losses for financial assets measured at amortized cost, which includes accounts receivable, and available-for-sale debt securities. The new guidance replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses and additional disclosures. As a smaller reporting company, this guidance is effective for fiscal years beginning after December 15, 2022. The Company does not expect the adoption of this guidance to have a material impact on its financial statements.

REVENUE
REVENUE	NOTE 3—REVENUE Contract Balances revenue is recognized, resulting in contract liabilities. Contract assets and liabilities are generally reported in the current assets and current liabilities sections of the consolidated balance sheet, at the end of each reporting period, based on the timing of the satisfaction of the related performance obligation(s). For multi-year software sales with annual invoicing, we perform a significant financing component calculation and recognize the associated interest income throughout the duration of the financing period. In addition, we reclassify the resulting contract asset balances as current and noncurrent receivables as receipt of the consideration is conditional only on the passage of time and there are no performance risk factors present. See the table below for a breakdown of contract assets and contract liabilities. ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, December 31, ​ 2022 2021 Contract assets ​ $ 32,249 ​ $ 18,639 Contract liabilities ​ $ 7,058 ​ $ 7,049 ​ Remaining performance obligations As of December 31, 2022, the Company had $130.0 million of remaining performance obligations, the majority of which are expected to be satisfied within the next year.

The related software acquired, which is capitalized within “Furniture, fixtures and equipment, net”, will be depreciated over four years when put into service at the end of the transition period underway to integrate the offering with our ISG GovernX cloud solution. ​ Change 4 Growth Acquisition ​ On October 31, 2022, a subsidiary of the Company executed an Asset Purchase Agreement with Change 4 Growth, LLC and consummated the acquisition of substantially all the assets, and assumed certain liabilities, of Change 4 Growth, LLC. The purchase price was comprised of $3.8 million of cash consideration, $0.6 million of shares of ISG common stock issued promptly after closing and Change 4 Growth, LLC will also have the right to receive additional consideration paid via earn-out payments, if certain financial targets are met. At the agreement date, the company estimated such earn-out payment would be $5.6 million. ​ ​ ​ ​ ​ Cash $ 3,450 Accrued working capital adjustment ​ ​ 378 ISG common stock ​ 600 Contingent consideration ​ 5,560 Total allocable purchase price ​ $ 9,988 ​ The amount of recognized identifiable assets acquired and liabilities assumed as of the agreement date: ​ ​ ​ ​ Accounts receivable and contract assets ​ $ 1,841 Intangible assets ​ 4,300 Accounts payable and accrued expense ​ ​ (428) Contract liabilities ​ (85) Net assets acquired ​ $ 5,628 ​ ​ ​ ​ Goodwill ​ $ 4,360 ​ The primary factors that drove the goodwill recognized, the majority of which is deductible for tax purposes, were the inclusion of legacy Change 4 Growth workforce and associated organizational change management expertise to enhance and expand the offerings of the ISG Enterprise Change service line. Costs associated with this acquisition are included in the selling, general and administrative expense in the Consolidated Statement of Income and Comprehensive Income and totaled $0.2 million during the year ended December 31, 2022. 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 date. 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 Estimated ​ Allocation Useful Lives Amortizable intangible assets: ​ ​ ​ ​ ​ Trademark and trade name ​ $ 1,100 3 years Customer relationships ​ ​ 2,900 ​ 8 years Noncompete agreements ​ ​ 300 ​ 2 years Total intangible assets ​ $ 4,300 ​ ​ ​ The Consolidated Statement of Income and Comprehensive Income includes revenue from the Change 4 Growth acquisition subsequent to the closing. Had the acquisition occurred as of January 1, 2022, approximately $7.0 million of revenue would have been recognized.

The material terms under the 2020 Credit Agreement are as follows: ● Each of the term loan facility and revolving credit facility has a maturity date of March 10, 2025 (the “Maturity Date”). ● 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 and its 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. ● At the Company’s option, the credit facility bears interest at a rate per annum equal to either (i) the “Base Rate” (which is the highest of (a) the rate publicly announced from time to time by the administrative agent as its “prime rate”, (b) the Federal Funds Rate plus 0.5% per annum and (c) the Eurodollar Rate , plus 1.0% ), plus the applicable margin or (ii) Eurodollar Rate (adjusted for maximum reserves) as determined by the Administrative Agent (as defined in the 2020 Credit Agreement), plus the applicable margin. The applicable margin is adjusted quarterly based upon the Company’s quarterly leverage ratio. ● The term loan is repayable in nineteen consecutive quarterly installments of $1,075,000 that commenced on June 30, 2020 and a final payment of the outstanding principal amount of the term loan on the Maturity Date. ● 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), transactions 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. ● The senior secured credit facility contains customary events of default, including cross-default to other material agreements, judgment default and change of control. The Company’s financial statements include outstanding borrowings of $79.2 million and $74.5 million as of December 31, 2022 and December 31, 2021, respectively, which are carried at amortized cost. The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company's outstanding borrowings was approximately $76.5 million and $73.6 million at December 31, 2022 and December 31, 2021, respectively. The fair values of debt have been estimated using a discounted cash flow rate used to Refer to Note 18 – Subsequent Event for additional information regarding the Company’s 2020 Credit Agreement.

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, ​ ​ 2022 2021 Balance, beginning of year ​ $ 1,639 ​ $ 1,569 ​ Additions as a result of tax positions taken during the current period ​ 76 ​ 101 ​ Reductions as a result of tax positions taken during a prior period ​ — ​ (31) ​ Balance, end of year ​ $ 1,715 ​ $ 1,639 ​ ​ 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 $1.0 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 $1.7 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 2015.

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 at our 2014 annual meeting with a subsequent amendment to the Incentive Plan approved by the Company’s stockholders at our 2017 annual meeting as discussed below. Subject to the terms 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 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. At the 2020 Annual Meeting, our stockholders approved an amendment to the Incentive Plan to increase the number of shares of common stock available for issuance under the Incentive Plan by 5,500,000 shares (the “Incentive Plan Amendment”). As of December 31, 2022, there were 3,085,373 and 847,124 shares available for grant under the Incentive Plan and ESPP, respectively. The Company recognized $7.5 million and $6.5 million in employee stock-based compensation expense during the years ended December 31, 2022 and 2021, 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 units (“RSU”), the vesting of which is subject to conditions and limitations established at the time of the grant. 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 termination of employment due to an 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 (Stock Price): ● Time-Based RSU Vesting: 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) so long as the employee continues to be employed through the vesting dates detailed in the award agreement, the RSUs will become vested according to the agreement. 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. As part of the Incentive Plan Amendment, dividends/dividend equivalents may be paid or credited on other stock-based awards (such as restricted stock units), but those dividends/dividend equivalents must be subject to the same vesting (or more stringent vesting) applicable to the underlying awards. The fair value of 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. A summary of the status of the Company’s RSUs issued under its Incentive Plan as of December 31, 2022 and changes during the years then ended, is presented below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted- ​ ​ ​ ​ Average ​ ​ ​ ​ ​ Grant Date ​ ​ ​ RSU ​ Fair Value ​ Non-vested at December 31, 2020 6,866 ​ $ 2.31 ​ Granted 1,112 ​ $ 6.07 ​ Vested (3,680) ​ $ 2.46 ​ Forfeited (278) ​ $ 2.51 ​ Non-vested at December 31, 2021 4,020 ​ $ 3.20 ​ Granted 1,527 ​ $ 6.57 ​ Vested (1,610) ​ $ 2.88 ​ Forfeited (117) ​ $ 3.37 ​ Non-vested at December 31, 2022 3,820 ​ $ 4.68 ​ ​ The total fair value of RSUs vested during the years ended December 31, 2022 and 2021 was $4.7 million and $9.0 million, respectively. As of December 31, 2022, there was $10.3 million of unrecognized compensation cost related to RSUs, which is expected to be recognized over a weighted-average period of 2.1 years. There were 3.9 million shares available for issuance at December 31, 2022 under the Incentive Plan. 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 3.6 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 three 20 For the year ended December 31, 2022, the Company issued 191,389 shares for the ESPP. There were 847,124 shares available for purchase at December 31, 2022 under the ESPP.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
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 revenue recognition guidance for contracts in which control is transferred to the customer over time affect the amounts of revenues, expenses, contract assets and contract liabilities. 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 evaluating goodwill for impairment, 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 is recorded as goodwill. Acquisition-related costs are expensed as incurred and recorded in selling, general and administrative expenses. ​
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 committed for rent deposits and are not available for general corporate purposes. ​
Accounts Receivable, Contract Assets and Allowance for Doubtful Accounts	Accounts Receivable, Contract Assets and Allowance for Doubtful Accounts Our trade receivables primarily consist of amounts due for services already performed. 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 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. Historically, the Company’s bad debt reserves and write-offs have not been significant. ​ 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. Historically, the Company’s unbilled receivable reserves and write-offs have not been significant. ​
Prepaid Expenses and Other Current Assets	Prepaid Expenses and Other Current Assets ​ Prepaid expenses and other current assets consist primarily of prepaid expenses for insurance, conferences, deposits for facilities, programs, software and promotion items. ​
Furniture, Fixtures and Equipment, net	Furniture, Fixtures and Equipment, net ​ Furniture, fixtures and equipment are recorded at cost. Depreciation is computed by applying the straight-line method over the estimated useful life of the assets, which ranges from two two The Company capitalizes internal-use software and website development costs and records these amounts within Furniture, Fixtures and Equipment, net. 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, 2022 and 2021, the Company capitalized $1.7 million and $0.8 million, respectively, of costs associated with system 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 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. A qualitative assessment is performed to determine whether the existence of events or circumstances leads to a determination that it is more likely than not the fair value of the reporting unit is less than its carrying amount. If, based on the evaluation, it is determined to be more likely than not that the fair value is less than the carrying value then goodwill is tested further for impairment. If the fair value of goodwill is lower than its carrying amount, an impairment loss is recognized in an amount equal to the difference. Subsequent increases in value are not recognized in the financial statements. There was no impairment of goodwill during the years ended December 31, 2022 and 2021, nor were any indicators identified in 2022 or 2021 that would suggest that it is more likely than not that the Company’s reporting unit is impaired.
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 asset group that contains the long-lived asset. If these or other factors indicate the carrying amount of the asset group, which is the lowest level for which identifiable cash flows exist that are separately identifiable from other cash flows, may not be recoverable, the Company determines whether impairment has occurred through the use of an undiscounted cash flow analysis. If impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset group. The fair value of the asset group 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. 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. ​
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. Deferred issuance costs are classified as a direct deduction to the long-term debt in the accompanying consolidated balance sheet. Amortization of debt issuance costs is included in interest expense and totaled $0.3 million and $0.4 million for the years ended December 31, 2022 and 2021, respectively.
Revenue Recognition	Revenue Recognition premise software, hybrid and software-as-a-service licenses, as well as other software-related services. Revenue associated with the software performance obligation is primarily recognized at the point at which the software is installed or access is granted.
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 $0.8 million and $0.3 million for the years ended December 31, 2022 and 2021, respectively. The increase was attributable to pandemic-related travel restrictions being lifted in 2022. ​
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 Company performance. ​
Stock-Based Compensation	Stock-Based Compensation We grant restricted stock units with a fair value that is determined based on the closing price of our common stock on the date of grant. Such grants generally vest ratably over a two four - We follow the provisions of accounting and disclosure requirements for share-based payments, including 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 most recently approved by the Board of Directors on August 5, 2021. ​ 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 or loss on the sale reflected as an adjustment to additional paid-in capital. ​
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 Translation ​
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 2022, there were no transfers of our financial assets between Level 1, Level 3 fair value ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basis of Fair Value Measurements ​ ​ December 31, 2022 ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ Total ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents $ 18 $ — $ — $ 18 ​ Total $ 18 $ — $ — $ 18 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration (1) $ — $ — $ 5,593 $ 5,593 ​ ​ $ — $ — $ 5,593 $ 5,593 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basis of Fair Value Measurements ​ ​ December 31, 2021 ​ ​ ​ Level 1 ​ Level 2 ​ Level 3 ​ ​ Total ​ Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Cash equivalents $ 1,018 $ — $ — $ 1,018 ​ Total $ 1,018 $ — $ — $ 1,018 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Contingent consideration (2) $ — $ — $ 2,420 $ 2,420 ​ ​ $ — $ — $ 2,420 $ 2,420 ​ (1) The current and noncurrent contingent consideration are included in “Accrued expenses and other current liabilities” and “Other liabilities,” respectively, as of December 31, 2022.

The fair value of debt is classified within Level 3 of the fair value hierarchy. The fair value of the Company’s outstanding borrowings was approximately $76.5 million and $73.6 million at December 31, 2022 and December 31, 2021, respectively. The fair values of debt have been estimated using a discounted cash flow
Income Taxes	Income Taxes
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In June 2016, the FASB issued new guidance on the measurement of credit losses for financial assets measured at amortized cost, which includes accounts receivable, and available-for-sale debt securities. The new guidance replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses and additional disclosures. As a smaller reporting company, this guidance is effective for fiscal years beginning after December 15, 2022. The Company does not expect the adoption of this guidance to have a material impact on its financial statements.
