Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation Basis of Presentation and Consolidation The accompanying interim unaudited condensed consolidated financial statements have been prepared by Synchronoss and in the opinion of management, include all adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary and entities in which the Company has a controlling interest. Investments in less than majority-owned companies in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. Investments in less than majority- owned companies in which the Company does not have the ability to exert significant influence over the operating and financial policies of the investee are accounted for using the cost method. All material intercompany transactions and accounts are eliminated in consolidation. For further information about the Company’s basis of presentation and consolidation or its significant accounting policies, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Recently Issued Accounting Standards Recent accounting pronouncements adopted Standard Description Effect on the financial statements Update 2022-04 - Liabilities—Supplier Finance Programs The amendments in this Update apply to all entities that use supplier finance programs in connection with the purchase of goods and services (herein described as buyer parties). Supplier finance programs, which also may be referred to as reverse factoring, payables finance, or structured payables arrangements, allow a buyer to offer its suppliers the option for access to payment in advance of an invoice due date, which is paid by a third-party finance provider or intermediary on the basis of invoices that the buyer has confirmed as valid. The Company evaluated these changes and determined that they have no material impact on the Company’s consolidated financial position or results of operations upon adoption. Date of adoption: January 1, 2023 Digital Experience Platform and Activation Solutions Sale On March 7, 2022, Synchronoss Technologies, Inc. and iQmetrix Global Ltd. (“iQmetrix”), entered into an Asset Purchase Agreement, pursuant to which Synchronoss has agreed to sell its Digital Experience Platform and activation solutions (the “DXP Business”) to iQmetrix for up to a total purchase price of $14 million. The purchase price is payable as follows: (i) $7.5 million on the closing date of the Transaction, (ii) $0.5 million deposited into an escrow account on the Closing Date, (iii) $1 million paid twelve (12) months from the Closing Date, and (iv) $5 million that may be payable as an earn-out. This transaction closed on May 11, 2022. The Company received the $7.5 million cash payment on the transaction close date. The Company received the $0.5 million payment in escrow during the third quarter of 2022 in accordance with the terms of the Asset Purchase Agreement. The remaining $1 million escrow payment has not been received by the Company in accordance with the agreement. As of September 30, 2023 the Company fully reserved for the asset and related receivables recorded within the Selling, general and administrative expenses line item on the income statement, and is pursuing collection of the payment. As of the close of the transaction, the Company determined the fair value of the earn-out provision was $3.6 million of which $3.0 million was recorded as an other current asset and the remaining portion was recorded as non-current other asset. In the fourth quarter of fiscal 2022, iQmetrix and the Company agreed that the required performance conditions were not met. This resulted in a write-off of the earn-out provision recorded within the Selling, general and administrative expenses line item on the income statement. The book value of the divested intangible assets associated with the DXP Business was $2.3 million. For the goodwill allocation, the fair value of the core reporting unit was estimated using a combination of the income approach, which incorporates the use of the discounted cash flow method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. Based on the fair value of the core reporting unit and the aggregate consideration received in the transaction, the Company determined the attributable fair value of goodwill to the DXP Business was $7.6 million. The transaction resulted in a $2.5 million gain for the year ended December 31, 2022. Accounts Receivable Securitization Facility On June 23, 2022 (the “Closing Date”), the Company and certain of its subsidiaries (together with the Company, the “Company Group”) entered into a $15 million accounts receivable securitization facility (the “A/R Facility”) with Norddeutsche Landesbank Girozentrale. The A/R Facility transaction includes (i) Receivables Purchase Agreements (the “Receivables Purchase Agreements”) dated as of the Closing Date, among the Company, as initial servicer, SN Technologies, LLC, a wholly owned special purpose subsidiary of the Company (“SN Technologies”), as seller, Norddeutsche Landesbank Girozentrale, as administrative agent (the “Administrative Agent”), and the purchasers party thereto, the group agents party thereto and the originators party thereto; (ii) Purchase and Sale Agreements (the “Purchase and Sale Agreements”) dated as of the Closing Date, between the Company Group, as originators (the “Originators”), and SN Technologies, as purchaser; (iii) the Administration Agreement (the “Administration Agreement”) dated as of the Closing Date, between the Company, as servicer, and Finacity Corporation, as administrator; and (iv) the Performance Guaranty (the “Performance Guaranty”) dated as of the Closing Date made by the Company in favor of the Administrative Agent. Pursuant to the Purchase and Sale Agreements, the Originators will sell existing and future accounts receivable [and related assets] (the “Receivables”) to SN Technologies in exchange for cash and/or subordinated notes. The Originators and SN Technologies intend the transactions contemplated by the Purchase and Sale Agreements to be true sales to SN Technologies by the respective Originators. Pursuant to the Receivables Purchase Agreement, SN Technologies will in turn grant an undivided security interest to the Administrative Agent in the Receivables in exchange for a credit facility permitting borrowings of up to $15 million outstanding from time to time. Yield is payable to the Administrative Agent under the Receivables Purchase Agreements at a variable rate based on the Norddeutsche Landesbank Girozentrale’s Hanover funding rate plus a 2.35% margin. The Company pays a commitment fee that shall equal 0.85% per annum on the average daily unused outstanding capital. Pursuant to the Performance Guaranty, the Company guarantees the performance of the Originators of their obligations under the Purchase and Sale Agreements. The Company has not agreed to guarantee any obligations of SN Technologies or the collection of any of the receivables and will not be responsible for any obligations to the extent the failure to perform such obligations by the Company or any Originators results from receivables being uncollectible on account of the insolvency, bankruptcy or lack of creditworthiness or other financial inability to pay of the related obligor. Unless earlier terminated or subsequently extended pursuant to the terms of the Receivables Purchase Agreement, the A/R Facility will expire on June 23, 2025. The foregoing description of the A/R Facility and the respective transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the full text of the Receivables Purchase Agreements, Purchase and Sale Agreements, Administration Agreement and Performance Guaranty, copies of which are filed as Exhibits 10.1, 10.2, 10.3 and 10.4, respectively, on Form 8-K filed with Securities and Exchange Commission on June 23, 2022. The Company drew $2.5 million on the A/R Facility in July of 2023, and had repaid the balance in full in September of 2023. The interest associated with the draw and repayment was not material for the period. The draw down and subsequent repayment of the A/R Facility represent financing activity, as reported in the Statement of Cash Flows. As of September 30, 2023 approximatel y $5.6 million

A receivable is a right to consideration that is unconditional (i.e. only the passage of time is required before payment is due). For example, the Company recognizes a receivable for revenues related to its time and materials and transaction or volume-based contracts. The Company presents such receivables in Trade accounts receivable, net in its Condensed Consolidated Statements of Financial Position at their net estimated realizable value. The Company maintains an allowance for credit losses to provide for the estimated amount of receivables that may not be collected. The allowance is based upon an assessment of customer creditworthiness, historical payment experience, the age of outstanding receivables and other economic indicators. A contract asset is a right to consideration that is conditional upon factors other than the passage of time. For example, the Company would record a contract asset if it records revenue on a professional services engagement but are not entitled to bill until the Company achieves specified milestones. Contract assets balance at September 30, 2023 is $6.1 million . Amounts collected in advance of services being provided are accounted for as contract liabilities, which are presented as deferred revenue on the accompanying Condensed Consolidated Balance Sheets and are realized with the associated revenue recognized under the contract. Nearly all of the Company's contract liabilities balance is related to services revenue, primarily subscription services contracts. The Company’s contract assets and liabilities are reported in a net position on a customer basis at the end of each reporting period. Significant changes in the contract liabilities balance (current and non-current) during the period are as follows: Contract Liabilities 1 Balance - January 1, 2023 $ 14,183 Revenue recognized in the period (172,039) Amounts billed but not initially recognized as revenue 177,366 Balance - September 30, 2023 $ 19,510 ________________________________ 1 Comprised of Deferred Revenue. $12.7 million of revenue recognized in the period was included in the contract liability balance at the beginning of the period. Transaction price allocated to the remaining performance obligations Topic 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied as of September 30, 2023. The Company has elected not to disclose transaction price allocated to remaining performance obligations for: 1. Contracts with an original duration of one year or less, including contracts that can be terminated for convenience without a substantive penalty; 2. Contracts for which the Company recognizes revenues based on the right to invoice for services performed; 3. Variable consideration allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation in accordance with Topic 606 Section 10-25-14(b), for which the criteria in Topic 606 Section 10-32-40 have been met. This applies to a limited number of situations where the Company is dependent upon data from a third party or where fees are highly variable. Many of the Company’s performance obligations meet one or more of these exemptions. Specifically, the Company has excluded the following from the Company’s remaining performance obligations, all of which will be resolved in the period in which amounts are known: • consideration for future transactions, above any contractual minimums • consideration for success-based transactions contingent on third party data • credits for failure to meet future service level requirements As of September 30, 2023, the aggregate amount of transaction price allocated to remaining performance obligations, other than those meeting the exclusion criteria above, was $268.6 million, of which approximately 59.8 percent is expected to be recognized as revenues within 2 years, and the remainder thereafter. Estimates of revenue expected to be recognized in future periods also exclude unexercised customer options to purchase services that do not represent material rights to the customer. Customer options that do not represent a material right are only accounted for in accordance with Topic 606 when the customer exercises its option to purchase additional goods or services.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In accordance with accounting principles generally accepted in the United States, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy prioritizes the inputs used to measure fair value as follows: • Level 1 - Observable inputs - quoted prices in active markets for identical assets and liabilities; • Level 2 - Observable inputs other than the quoted prices in active markets for identical assets and liabilities includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and • Level 3 - Unobservable inputs - includes amounts derived from valuation models where one or more significant inputs are unobservable and require the Company to develop relevant assumptions. The following is a summary of assets, liabilities and redeemable noncontrolling interests and their related classifications under the fair value hierarchy: September 30, 2023 Total (Level 1) (Level 2) (Level 3) Assets Cash and cash equivalents $ 17,574 $ 17,574 $ — $ — Total assets $ 17,574 $ 17,574 $ — $ — Temporary equity Redeemable noncontrolling interests 1 $ 12,500 $ — $ — $ 12,500 Total temporary equity $ 12,500 $ — $ — $ 12,500 December 31, 2022 Total (Level 1) (Level 2) (Level 3) Assets Cash and cash equivalents $ 21,921 $ 21,921 $ — $ — Total assets $ 21,921 $ 21,921 $ — $ — Temporary Equity Redeemable noncontrolling interests 1 $ 12,500 $ — $ — $ 12,500 Total temporary equity $ 12,500 $ — $ — $ 12,500 ________________________________ 1 Put arrangements held by the noncontrolling interests in certain of the Company’s joint venture. Redeemable Noncontrolling Interests The redeemable noncontrolling interests recorded at fair value are put arrangements held by the noncontrolling interests in certain of the Company’s joint ventures. The Company recognizes changes in the redemption value immediately as they occur and adjusts the carrying value of the noncontrolling interest to the greater of the estimated redemption value, which approximates fair value, at the end of each reporting period or the initial carrying amount. The fair value of the redeemable noncontrolling interests was estimated by applying an income approach using a discounted cash flow analysis. This fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. Significant changes in the underlying assumptions used to value the redeemable noncontrolling interests could significantly increase or decrease the fair value estimates recorded in the Condensed Consolidated Balance Sheets.

Leases [Abstract]
Leases	Leases The Company has entered into contracts with third parties to lease a variety of assets, including certain real estate, equipment, automobiles and other assets. The Company’s leases frequently allow for lease payments that could vary based on factors such as inflation or the degree of utilization of the underlying asset. For example, certain of the Company’s real estate leases could require us to make payments that vary based on common area maintenance charges, insurance and other charges. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company is party to certain sublease arrangements, primarily related to the Company’s real estate leases, where it acts as the lessee and intermediate lessor.

The offering was conducted pursuant to an underwriting agreement (the “Notes Underwriting Agreement”) dated June 25, 2021, by and among the Company and B. Riley Securities, Inc., as representative of the several underwriters (the “Notes Underwriters”). At the closing, the Company issued $125.0 million aggregate principal amount of Senior Notes, inclusive of $5.0 million aggregate principal amount of Senior Notes issued pursuant to the full exercise of the Notes Underwriters’ option to purchase additional Senior Notes. The Notes Underwriting Agreement contains customary representations, warranties and covenants of the Company, customary conditions to closing, indemnification obligations of the Company and the Notes Underwriters, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. On June 30, 2021, the Company entered into an indenture (the “Base Indenture”) and a supplemental indenture (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) with The Bank of New York Mellon Trust Company National Association, as trustee (the “Trustee”), between the Company and the Trustee. The Indenture establishes the form and provides for the issuance of the Senior Notes. The Senior Notes are senior unsecured obligations of the Company and rank equally in right of payment with all of the Company’s existing and future senior unsecured and unsubordinated indebtedness. The Senior Notes are effectively subordinated in right of payment to all of the Company’s existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally subordinated to all existing and future indebtedness of the Company’s subsidiaries, including trade payables. The Senior Notes bear interest at the rate of 8.375% per annum. Interest on the Senior Notes is payable quarterly in arrears on January 31, April 30, July 31 and October 31 of each year, commencing on July 31, 2021. The Senior Notes will mature on June 30, 2026, unless redeemed prior to maturity. The Company may, at its option, at any time and from time to time, redeem the Senior Notes for cash in whole or in part (i) on or after June 30, 2022 and prior to June 30, 2023, at a price equal to $25.75 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or after June 30, 2023 and prior to June 30, 2024, at a price equal to $25.50 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, (iii) on or after June 30, 2024 and prior to June 30, 2025, at a price equal to $25.25 per Senior Note, plus accrued and unpaid interest to, but excluding, the date of redemption, and (iv) on or after June 30, 2025 and prior to maturity, at a price equal to 100% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption. On and after any redemption date, interest will cease to accrue on the redeemed Senior Notes. The Company has not redeemed any of the Senior Notes as of September 30, 2023. The Indenture contains customary events of default and cure provisions. If an uncured default occurs and is continuing, the Trustee or the holders of at least 25% of the principal amount of the Senior Notes may declare the entire amount of the Senior Notes, together with accrued and unpaid interest, if any, to be immediately due and payable. In the case of an event of default involving the Company’s bankruptcy, insolvency or reorganization, the principal of, and accrued and unpaid interest on, the principal amount of the Senior Notes, together with accrued and unpaid interest, if any, will automatically, and without any declaration or other action on the part of the Trustee or the holders of the Senior Notes, become due and payable.

Capital Structure	Capital Structure Common Stock Each holder of common stock is entitled to vote on all matters and is entitled to one vote for each share held. Dividends on common stock will be paid when, and if, declared by the Company’s Board of Directors. No dividends have ever been declared or paid by the Company. Preferred Stock The Company’s Board of Directors (the “Board”) is authorized to issue preferred shares and has the discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of preferred stock. Series B Non-Convertible Preferred Stock On June 30, 2021, the Company closed a private placement of 75,000 shares of its Series B Perpetual Non-Convertible Preferred Stock, par value $0.0001 per share, with an initial liquidation preference of $1,000 per share (the “Series B Preferred Stock”), for net proceeds of $72.5 million (the “Series B Transaction”). The sale of the Series B Preferred Stock was pursuant to the Series B Preferred Stock Purchase Agreement, dated as of June 24, 2021 (the “Series B Purchase Agreement”), between the Company and B. Riley Principal Investments, LLC (“BRPI”). In connection with the closing of the Series B Transaction, the Company (i) filed a Certificate of Designation with the State of Delaware setting forth the rights, preferences, privileges, qualifications, restrictions and limitations on the Series B Preferred Stock (the “Series B Certificate”) and (ii) entered into an Investor Rights Agreement with B. Riley Financial, Inc. (“B. Riley Financial”) and BRPI setting forth certain governance and registration rights of B. Riley Financial with respect to the Company. Certificate of Designation of the Series B Preferred Stock The rights, preferences, privileges, qualifications, restrictions and limitations of the shares of Series B Preferred Stock are set forth in the Series B Certificate. Under the Series B Certificate, the holders of the Series B Preferred Stock are entitled to receive, on each share of Series B Preferred Stock on a quarterly basis, an amount equal to the dividend rate, as described in the following sentence, divided by four and multiplied by the then-applicable Liquidation Preference per share of Series B Preferred Stock (collectively, the “Preferred Dividends”). The dividend rate is (1) 9.5% per annum for the period commencing on June 30, 2021 and ending on and including December 31, 2021, (2) 13% per annum for the year commencing on January 1, 2022 and ending on and including December 31, 2022; and (3) 14% per annum for the year commencing on January 1, 2023 and thereafter. The Preferred Dividends will be due in cash on January 1, April 1, July 1 and October 1 of each year (each, a “Series B Dividend Payment Date”). The Company may choose to pay the Series B Preferred Dividends in cash or in additional shares of Series B Preferred Stock. In the event the Company does not declare and pay a dividend in cash on any Series B Dividend Payment Date, the unpaid amount of the Preferred Dividend will be added to the Liquidation Preference. As of September 30, 2023, the Liquidation Value and Redemption Value of the Series B Preferred Shares was $73.2 million . On and after the fifth anniversary of the date of issuance, holders of shares of Series B Preferred Stock will have the right to cause the Company to redeem each share of Series B Preferred Stock for cash in an amount equal to the sum of the current liquidation preference and any accrued dividends. Each share of Series B Preferred Stock will also be redeemable at the option of the holder upon the occurrence of a “Fundamental Change” at (i) par in the case of a payment in cash or (ii) 1.5 times par in the case of payment in shares of Common Stock (such shares being, “Registrable Securities”), subject to certain limitations on the amount of stock that could be issued to the holders of Series B Stock. In addition, the Company will be permitted to redeem outstanding shares of the Series B Preferred Stock at any time for the sum of the then-applicable Liquidation Preference and the accrued but unpaid dividends. Pursuant to the Series B Certificate, the Company will be required to use (i) the first $50.0 million of proceeds from certain transactions (i.e., disposition, sale of assets, tax refunds) received by the Company to redeem for cash, shares of the Series B Preferred Stock, on a pro rata basis among each holder of Series B Preferred Stock and (ii) the next $25.0 million of proceeds from certain transactions received by the Company may be used by the Company to buy back shares of Common Stock and to the extent, not used for such purpose by the Company, to redeem, for cash, shares of the Series B Preferred Stock, on a pro rata basis among each holder of the Series B Preferred Stock. The Company shall be required to obtain the prior written consent of the holders holding at least a majority of the outstanding shares of the Series B Preferred Stock before taking certain actions, including: (i) certain dividends, repayments and redemptions; (ii) any amendment to the Company’s certificate of incorporation that adversely affects the rights, preferences, privileges or voting powers of the Series B Preferred Stock; and (iii) issuances of stock ranking senior or equivalent to shares of the Series B Preferred Stock (including additional shares of the Series B Preferred Stock) in the priority of payment of dividends or in the distribution of assets upon any liquidation, dissolution or winding up of the Company. Other than with respect to the foregoing consent rights, the Series B Preferred Stock is non-voting stock. Investor Rights Agreement On June 30, 2021, the Company, B. Riley Financial and BRPI entered into an Investor Rights Agreement (the “Investor Rights Agreement”). Pursuant to the Investor Rights Agreement, for so long as affiliates of B. Riley Financial beneficially own at least 10% of the outstanding shares of common stock (unless such equity threshold percentage is not met due to dilution from equity issuances), B. Riley Financial is entitled to nominate one Class II director (the “B. Riley Nominee”) to the Company’s board of directors (the “Board”), who shall be an employee of B. Riley Financial or its affiliates and is approved by the Board, such approval not to be unreasonably withheld. For so long as affiliates of B. Riley Financial beneficially own 5% or more but less than 10% of the outstanding shares of common stock (unless such equity threshold percentage is not met due to dilution from equity issuances), B. Riley Financial is entitled to certain board observer rights.

The Company’s performance based cash unit (“PBCU”) awards granted to executives under the Long Term Incentive (“LTI”) Pla ns have been accounted for as liability awards, due to the Company’s intent and the ability to settle such awards in cash upon vesting and the Company has reflected such awards in accrued expenses. As of September 30, 2023, the liability for such awards is approximately $0.8 million. Stock-Based Compensation The following table summarizes stock-based compensation expense related to all of the Company’s stock awards included by operating expense categories, as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Cost of revenues $ 163 $ 232 $ 576 $ 592 Research and development 373 494 1,362 1,366 Selling, general and administrative 705 1,075 2,667 2,734 Total stock-based compensation expense $ 1,241 $ 1,801 $ 4,605 $ 4,692 The following table summarizes stock-based compensation expense related to all of the Company’s stock awards included by award type, as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Stock options $ 428 $ 779 $ 1,395 $ 2,019 Restricted stock awards 929 933 2,794 2,320 Performance based cash units (116) 89 416 353 Total stock-based compensation before taxes $ 1,241 $ 1,801 $ 4,605 $ 4,692 Tax benefit $ 243 $ 364 $ 918 $ 931 The total stock-based compensation cost related to unvested equity awards as of September 30, 2023 was approximately $6.3 million.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognized an income tax expense of approximately $2.7 million and $1.7 million during the nine months ended September 30, 2023 and 2022, respectively. The effective tax rate was approximately (13.9)% for the nine months ended September 30, 2023,which was lower than the U.S. federal statutory rate primarily due to pre-tax losses in jurisdictions where full valuation allowances have been recorded and certain jurisdictions projecting current income tax expense. The Company’s income tax expense for the period is driven by the enacted Internal Revenue Code Section 174 rules that require the Company to amortize qualifying research and development expenses over five years or fifteen years depending on the jurisdiction where such activities are performed and by operating income generated in certain foreign jurisdictions. The Company’s effective tax rate was approximately 21.9% for the nine months ended September 30, 2022, which approximated the U.S. federal statutory rate. The Company continues to consider all available evidence, including historical profitability and projections of future taxable income together with new evidence, both positive and negative, that could affect the view of the future realization of deferred tax assets. As a result of the assessment, no change was recorded by the Company to the valuation allowance during the nine months ended September 30, 2023. On August 16, 2022, the Inflation Reduction Act of 2022 ("IRA") was signed into law. This legislation includes significant changes relating to tax, climate change, energy and health care. Among other provisions, the IRA introduces a corporate alternative minimum tax assessed on financial statement income of certain large corporations and an excise tax on share repurchases. The IRA does not have a material impact on the Company’s financial statements in the period ended September 30, 2023. During 2021 the Internal Revenue Service commenced an audit of certain of the Company’s prior year U.S. federal income tax filings, including the 2013 through 2020 tax years. The audit is currently ongoing and while the receipt of the associated refunds would materially improve its financial position, the Company does not believe that the results of this audit will have a material effect on its results of operations. The Company received $4.3 million in federal tax refunds in the second quarter of 2022. There is no change to the Company’s position on the remaining tax refunds.

Earnings Per Share [Abstract]
Earnings per Common Share (EPS)	Earnings per Common Share (“EPS”) Basic EPS is computed based upon the weighted average number of common shares outstanding for the year. Diluted EPS is computed based upon the weighted average number of common shares outstanding for the year plus the dilutive effect of common stock equivalents using the treasury stock method and the average market price of the Company’s common stock for the year. The Company includes participating securities (Redeemable Convertible Preferred Stock - Participation with Dividends on Common Stock that contain preferred dividend) in the computation of EPS pursuant to the two-class method. The two-class method of computing earnings per share is an allocation method that calculates earnings per share for common stock and participating securities. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company. The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income attributable to common stockholders per common share from operations.

Commitments, Contingencies and Other	Commitments, Contingencies and Other Non-cancelable agreements The Company has various non-cancelable arrangements such as services for hosting, support, and software that expire at various dates, with the latest expiration in 2027. Aggregate annual future minimum payments under non-cancelable agreements as of September 30, 2023 are as follows: Year Non-cancelable agreements The remainder of 2023 $ 4,836 2024 21,450 2025 17,441 2026 286 2027 13 Total $ 44,026 Legal Matters In the ordinary course of business, the Company is regularly subject to various claims, suits, regulatory inquiries and investigations. The Company records a liability for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable, and the loss can be reasonably estimated. Management has also identified certain other legal matters where they believe an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against the Company, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the Company’s business, financial position, results of operations, or cash flows, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. The Company also evaluates other contingent matters, including income and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. In the third quarter of 2017, the SEC and Department of Justice (the “DoJ”) initiated investigations in connection with certain financial transactions that the Company effected in 2015 and 2016 and its disclosure of and accounting for such transactions, which the Company restated in the third quarter of 2018 in its restated annual and quarterly financial statements for 2015 and 2016. On June 7, 2022 the SEC approved the Offer of Settlement and filed an Order Instituting Cease-And-Desist Proceedings pursuant to Section 21C of the Securities Exchange Act of 1934, Making Findings, and Imposing a Cease-And-Desist Order (the “SEC Order”). Pursuant to the terms of the SEC Order, the Company consented to pay a civil penalty in the amount of $12.5 million in equal quarterly installments over two years and to cease and desist from committing or causing any violations of Sections 10(b), 13(a), 13(b)(2)(A) and 13(b)(2)(B) of the Exchange Act and the associated rules thereunder. In addition, failure to comply with the provisions of the SEC Order could result in further actions by one or both governmental agencies which could have a material adverse effect on the Company’s results of operations. The expense associated with this settlement of the SEC Order has previously been accrued in the Company’s financial statements. Also on June 7, 2022, the SEC filed a civil action against two former members of the Company’s management team, alleging misconduct arising out of the restated transactions that took place in 2015 and 2016 investigated by the SEC as set forth above. The Company may be required to indemnify the former members of management in that action for certain costs and expenses, including reasonable attorney’s fees. At this time it is not possible for us to estimate the amount, if any, of such indemnification obligations. On or about July 12, 2023 Company filed a complaint in the Superior Court of the State of Delaware against iQmetrix Global Ltd. (“iQmetrix") for breach of the asset purchase and transition services agreements by and between the Company and iQmetrix as a result of iQmetrix’s failure to pay amounts due under those agreements in excess of $1,200,000. On September 11, 2023 iQmetrix filed its “Answer Defenses and Counterclaims” against Company, claiming Company breached the asset purchase, transition services and software license agreements, committed fraud and breached the implied covenant of good faith and fair dealing entitling iQmetrix to an amount to be determined at trial. On October 10, 2023, Company filed its “Answer to Defendant’s Counterclaims” denying all counts asserted by iQmetrix and asserting certain affirmative defenses thereto. The Company believes that the counterclaims are without merit, and the Company intends to defend all such counterclaims. Due to the inherent uncertainty of litigation, the Company cannot predict the outcome of the litigation and can give no assurance that the asserted claims will not have a material adverse effect on its financial position, prospects, or results of operations.

Fair Value Measurements	In accordance with accounting principles generally accepted in the United States, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy prioritizes the inputs used to measure fair value as follows: • Level 1 - Observable inputs - quoted prices in active markets for identical assets and liabilities; • Level 2 - Observable inputs other than the quoted prices in active markets for identical assets and liabilities includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and • Level 3 - Unobservable inputs - includes amounts derived from valuation models where one or more significant inputs are unobservable and require the Company to develop relevant assumptions.
