Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The condensed consolidated financial statements as of June 30, 2017 and for the three and six months ended June 30, 2017 and 2016 are unaudited, but in the opinion of management, include all adjustments (consisting only of normal recurring 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 for 2017 and 2016 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as they have been filed prior to this quarterly report on Form 10-Q and certain prior year amounts have been restated. Refer to Note 3 - Restatement of Previously Issued Consolidated Financial Statements and Note 14 - Subsequent Events Review for background on the restatement of previously issued financial statements and Nasdaq compliance, respectively. The results of operations for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ended December 31, 2017 . 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, 2017. Restricted Cash Restricted cash includes amounts to various deposits, escrows and other cash collateral that are restricted by contractual obligation. Restricted cash includes amounts to various deposits, escrows and other cash collateral that are restricted by contractual obligation. As of December 31, 2016, the Company held $30 million in escrow related to the Company’s guarantee of STIH’s Third Party Note. As of June 30, 2017, there was a zero balance related to the guarantee. $23.8 million was released upon assignment of certain customer contracts contributed in the sale of our BPO business. $6.2 million distribution was made to Goldman to fulfill the Company’s guarantee obligation to Goldman. Remaining amounts were primarily attributed to cash held in transit (see Note 6 - Investments in Affiliates and Related Transactions), and operating cash held by Zentry, which cannot be used to fulfill the obligations of the Company as a whole. Recently Issued Accounting Standards Recent accounting pronouncements adopted Standard Description Effect on the financial statements ASU 2017-04 Simplifying the Test for Goodwill Impairment In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance which eliminates Step 2 from the goodwill impairment test. Under the amendments in this Update, an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Accounting Standard Update (“ASU”) 2017-04 also eliminates the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. ASU 2017-04 is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company elected to early adopt this ASU for annual and interim goodwill impairment testing dates after January 1, 2017. The adoption of this ASU had no impact on the Company’s consolidated financial statements. Date of adoption: January 1, 2020. Standard Description Effect on the financial statements ASU 2017-01 Business Combinations (Topic 805), Clarifying the Definition of a Business In January 2017, FASB changed its definition of a business in an effort to help entities determine whether a set of transferred assets and activities is a business. The guidance requires an entity to first evaluate whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of transferred assets and activities is not a business. If the threshold is not met, the entity evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance narrows the definition of outputs by more closely aligning it with how outputs are described in the new revenue guidance. The guidance is effective for public business entities for annual periods beginning after 15 December 2017, and interim periods within those periods. For all other entities, it is effective for annual periods beginning after 15 December 2018, and interim periods within annual periods beginning after 15 December 2019. Early adoption is permitted. The Company adopted this ASU on January 1, 2017 on a prospective basis. The adoption of this ASU had no impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. ASU 2016-18 Statement of Cash Flows (Topic 230) In November 2016, the FASB issued ASU 2016-18, which amends the guidance in ASC 230, including providing additional guidance related to transfers between cash and restricted cash and how entities present, in their statement of cash flows, the cash receipts and cash payments that directly affect the restricted cash accounts. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted this ASU on January 1, 2017 to each period presented and applied the changes to the condensed consolidated statements of cash flows. Date of adoption: January 1, 2017. ASU 2016-17 Consolidation: Interest Held through Related Parties That Are under Common Control In October 2016, the FASB issued ASU 2016-17, to amend the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity should treat indirect interests in the entity held through related parties that are under common control within the reporting entity when determining whether it is the primary beneficiary of that variable interest entity. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted this ASU on January 1, 2017 on a prospective basis. The adoption of this ASU had no significant impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. ASU 2016-16 Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU 2016-16, which requires entities to recognize at the transaction date the income tax effects for intra-entity transfers of assets other than inventory. The standard is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this ASU on January 1, 2017 on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings of $3.2 million as of January 1, 2017. Date of adoption: January 1, 2017. ASU 2016-15 Statement of Cash Flows In August 2016, the FASB issued ASU 2016-15 which will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017. ASU 2016-15 will require adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable. The Company adopted this ASU on January 1, 2017 using a retrospective transition method. The adoption of this ASU had no impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. Standards issued not yet adopted Standard Description Effect on the financial statements ASU 2017-09 Stock Compensation (Topic 718), Scope of Modification Accounting In May 2017, FASB issued guidance which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The guidance also clarifies that a modification to an award could be significant and therefore require disclosure, even if modification accounting is not required. ASU 2017-09 is effective for fiscal years, and interim periods within those years, beginning after December 31, 2017. Early adoption is permitted as of the beginning of an annual period for which financial statements have not been issued. ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the impact of the adoption of this ASU on its condensed consolidated financial statements. Date of adoption: January 1, 2018. ASU 2016-13 Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13 which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The ASU is effective for public companies in annual periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted beginning after December 15, 2018 and interim periods within those years. The Company is currently evaluating the impact of the adoption of this ASU on its condensed consolidated financial statements. Date of adoption: January 1, 2020. ASU 2016-02 Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02 which requires lessees to recognize, for all leases of 12 months or more, a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset for the lease term. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature of an entity’s leasing activities. This ASU is effective for public reporting companies for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and must be adopted using a modified retrospective approach. The Company is in the process of evaluating the effect of the new guidance on its condensed consolidated financial statements and disclosures. Date of adoption: January 1, 2019. In May 2014, the FASB issued a new accounting standard related to revenue recognition, ASU 2014-09, “Revenue from Contracts with Customers,” (“ASC 606” or “Topic 606”). The new standard supersedes the existing revenue recognition requirements under U.S. GAAP and requires entities to recognize revenue when they transfer control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. It also requires increased disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows arising from contracts with customers. On January 1, 2018, we adopted Topic 606 applying the modified retrospective method to all contracts that were not completed as of January 1, 2018. We recorded a net reduction to opening retained earnings of approximately $10.1 million as of January 1, 2018 due to the cumulative impact of adopting Topic 606. The impact of adoption primarily relates to (1) the delayed pattern of recognition under Topic 606 for certain professional services revenue when such professional services involve the customization of features and functionality for subscription services customers and (2) the earlier pattern of recognition under Topic 606 for license revenue when the Company provides hosting services for on-premise license customers. In the case of professional services that involve the customization of features and functionality for subscription services, under historic accounting policies the professional services were considered to have standalone value, and as a result were recognized as the services were performed. Under Topic 606, such professional services are not considered to be a distinct performance obligation within the context of the subscription services contract, and as such customization services revenue is recognized over the shorter of the estimated remaining life of the subscription software (typically three years) or the remaining term of the subscription services contract. In the case of license contracts sold in association with hosting, under historic accounting policies the license revenue was recognized over the hosting term due to the lack of vendor specific objective evidence (“VSOE”) of fair value for the hosting services. Under Topic 606, VSOE is no longer required in order to allocate revenue between the license and the hosting services, and the license revenue is generally recognized upon delivery of the software based on the relative allocation of the contract price based on the established standalone selling price (“SSP”) Additional impacts of adoption include (1) in certain cases changes in the amount allocated to the various performance obligation in accordance with the relative standalone selling price method required by Topic 606 compared to the amount allocated to the various elements in accordance with the residual method or the relative selling price method, as applicable, under historic accounting policies, (2) the capitalization and subsequent amortization of certain sales commissions as costs to obtain a contract under ASC 340-40, whereas under historic accounting policies all such amounts were expensed as incurred (3) the timing and amount of revenue recognition for certain sales contracts that are considered to involve variable consideration under Topic 606, but were considered to either not be fixed or determinable or to involve contingent revenue features under historic accounting policies, (4) in certain limited cases, the accounting for discounted customer options to purchase future software or services as material rights under Topic 606, as well as (5) the income tax impact of the above items, as applicable. In connection with the adoption of Topic 606 and the related cost accounting guidance under ASC 340, we are required to capitalize certain contract acquisition costs consisting primarily of commissions and bonuses paid when contracts are signed. As of January 1, 2018, the date we adopted Topic 606, we capitalized $0.7 million in contract acquisition costs related to contracts that were not completed.

Restatement of Previously Issue

Restatement of Previously Issued Consolidated Financial Statements	6 Months Ended

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	Restatement of Previously Issued Consolidated Financial Statements The Company has restated its audited consolidated financial statements for the years ended December 31, 2016 and 2015 for the matters described below. The effects of these restatement adjustments on (i) the Company’s Consolidated Balance Sheet at December 31, 2016, (ii) the Company’s Consolidated Statement of Operations for the years ended December 31, 2016 and 2015, (iii) the Company’s Consolidated Statements of Comprehensive Income for the years ended December 31, 2016 and 2015, (iv) the Company’s Consolidated Statements of Stockholders’ Equity for the years ended December 31, 2016 and 2015 and (v) the Company’s Consolidated Statement of Cash Flows for the years ended December 31, 2016 and 2015 are presented in the Company’s 2017 Form 10-K. The effects of the restatement adjustments on the Company’s unaudited Condensed Consolidated financial statements as of June 30, 2016 and for the three and six month periods then ended are reflected in the tables below. The individual restatement matters that underlie the restatement adjustments are described below. Revenue Recognition Adjustments Related to Hosting Services The Company typically sells hosting services to its subscription services customers, as well as to certain software license customers. As part of the Company’s review of its historical accounting, it has determined that adjustments are required related to certain transactions in each of these two categories of customers that purchase hosting services. It was observed that in certain instances, the Company has historically entered into hosting arrangements that included various components to the fee structure with certain fees accelerated during the initial years of the arrangement. Historically, the Company recognized the accelerated fees as billed and maintenance and support fees were recognized on a straight-line basis through the term of the arrangement. However, the Company has determined to revise its accounting treatment for certain hosting services to reflect revenue recognition on a straight-line basis for such fees over the appropriate period of time during which (i) the benefits of hosting services were provided to the customer or (ii) the customer benefited from the set-up fees. The revised accounting treatment for the revenue recognition is reflected in the restated consolidated financial statements, whereby there has been a deferral of a portion of the accelerated fees out of the initial period of the arrangement, and recognition of those deferred amounts in the later periods of the hosting services arrangement. In the case of certain perpetual software license customers, the Company historically recognized the perpetual software license fee revenue on an upfront basis. The Company has determined to revise its accounting treatment of that software license fee revenue to recognize it ratably over a period of time due to the inclusion of hosting services, as part of the same multiple element arrangement. In certain of these cases, the Company had entered into a separate hosting services contract with the customer that the Company has now determined should have been combined with the software license agreement and treated as part of a larger multiple element arrangement. In accordance with the software revenue recognition rules, since the Company cannot establish vendor specific objective evidence of fair value of the hosting services, the software license element cannot be separated from the hosting services. The revised accounting treatment for the revenue recognition is reflected in the restated consolidated financial statements, whereby the bundled arrangement fees have been recognized ratably over the economic life of the hosting services. Revenue Recognition Adjustments Related to Establishing Persuasive Evidence of an Arrangement and Other Revenue Adjustments The Company historically has had, and continues to have, contractual arrangements with certain customers whereby there is an established master services agreement that includes general terms and conditions. Such master services agreements contemplate the delivery by the customer of purchasing documentation for purposes of completing orders, indicating the nature, price and quantity of products and services ordered. In certain cases, the Company historically formed a view that persuasive evidence of an arrangement existed relating to such orders based upon its receipt from a customer of written confirmation of the order and commitment to pay the agreed price, such as a quote approval sent by the customer in response to a quote issued by the Company, but prior to that customer’s subsequent delivery to the Company an executed statement of work or, in some instances, a purchase order, pursuant to a master services agreement. The Company has determined, in certain situations, to revise the timing of revenue recognition to when it received final formal contract documentation, which occurred in a future period. In those cases where the adjustment to defer revenue has been recorded prior to when cash payment was received from the customer, the balance sheet impact has been to reduce the related accounts receivable balance, whereas the balance sheet impact of these adjustments after the receipt of cash payment from the customer has been to increase accrued liabilities. The Company also adjusted revenue recognition in connection with certain other transactions, including (i) where the payment obligation on the date of sale was found not to have been fixed and determinable; (ii) where collectability was not reasonably assured; (iii) where the software delivered to the customer was ultimately deemed not to have met acceptance criteria; or (iv) where formal acceptance was not obtained. In certain situations, these adjustments represent issues related to the timing of revenue recognition, while in other cases, these adjustments represent amounts that had subsequently been written-off to bad debt expense (whereby now both the revenue and the related bad debt expense has been reversed). Adjustments Related to Accounting for Acquisitions and Divestiture The Company has identified and corrected errors related to fees received under license agreements entered into with parties of certain historical acquisitions and a divestiture. In each case, the Company had originally treated the license agreement as a separate transaction and recorded the license fees on a gross basis as revenue. The Company has determined to revise its accounting treatment of the license arrangements, to record the license fees as part of the accounting for the acquisition or divestiture, as follows: • In certain cases, the Company entered into a license agreement as part of settling prior intellectual property infringement claims against an acquired entity and/or its selling parent company and affiliates. Historically, the Company had recognized these license fees separately as revenue. However, the Company has determined to net these license fees against the consideration paid as part of the acquisitions, resulting in a reduction of the goodwill and/or intangible assets recorded in purchase accounting. • The Company’s consolidated joint venture Zentry LLC (“Zentry”) and the Company’s partner in that joint venture entered into a license agreement in December 2015 at the same time as the formation of the joint venture. Historically, the Company recorded the license fees as revenue separately from the Zentry formation. The Company has determined to net these license fees against the cash contributions paid as part of the joint venture formation, resulting in a reduction of the goodwill and intangible assets recorded in purchase accounting. • The Company entered into a licensing agreement in December 2016 with Sequential Technology International, LLC (“STIN”) shortly after closing the divestiture of its activation business to Sequential Technology International Holdings, LLC (“STIH”). Historically, the Company recorded the license fees as revenue separately from the accounting for the divestiture. The Company has determined to classify these license fees as additional gain on sale of the activation exception handling business. • The Company made adjustments to reduce the contingent consideration payable to shareholders of Razorsight Corporation (“Razorsight”), which was acquired by the Company in August 2015, and the related losses previously recorded to adjust that liability to fair value, as a result of the determination that many of the sales of Razorsight software that had originally been included in the earn-out calculation have now been adjusted as part of the restatement. • The Company made adjustments to record the fair value of the Company’s guarantee of certain of STIN’s debt as part of the divestiture of its activation exception handling business to STIH in December 2016, to record the sellers note extended in the transaction at fair value, and to adjust certain receivables and other assets sold in the transaction. • The Company made certain adjustments to the opening balances of Openwave Messaging, Inc. (“Openwave”) and SNCR, LLC (“SNCR, LLC”); impacting deferred revenue, goodwill and intangibles. Adjustments in deferred revenue and intangibles resulted were reported post-acquisition as revenues and costs were realized. Other Adjustments and Capitalized Software The Company also identified and corrected certain errors in the amounts reported as capitalized software development. These adjustments were primarily around (i) the recognition of impairment or immediate expensing of certain previously capitalized software development costs and (ii) revisions of amounts capitalized and the timing of when such capitalized costs are amortized. Adjustments pertaining to capitalized software development were driven primarily due to misalignment on the unit of account being measured in tracking project progress and ultimately general release as well as the appropriateness of the capitalization of certain administrative costs. The Company also identified and corrected certain other errors, primarily due to timing of recognition of (i) stock-based compensation arrangements, (ii) accruals and reserves, (iii) noncontrolling interests and (iv) impairment charges. Impairment charges were primarily due to long-lived asset impairments realized on SNCR, LLC assets, due to continued delays in product development and sales. Additionally, the Company identified certain prior year balance sheet classification adjustments requiring, the most significant of which, a reclassification between cash and restricted cash due to certain contractual restrictions on cash balances, and reclassifications between treasury stock and additional paid-in-capital due to share issuances from the Company’s common stock pool, rather than its treasury stock. Income Taxes The Company recorded adjustments to income taxes to reflect the impact of the restatement adjustments, as well as a discrete tax adjustment to record a valuation allowance at a specific foreign jurisdiction in an earlier year than originally recorded. See Note 11 - Income Taxes for discussion of the related impact to the Company’s effective tax rate.

Acquisitions and Divestitures	Acquisitions and Divestitures Acquisitions 2017 Transactions Intralinks On January 19, 2017, the Company purchased all outstanding shares of Intralinks Holdings, Inc. (“Intralinks”). In connection with the acquisition, the Company entered into a $900.0 million senior secured term loan (the “2017 Term Facility”), as of the date of acquisition. Intralinks is a global technology provider of Software as a service (“SaaS”) solutions for secure enterprise content collaboration within and among organizations. Intralinks’ cloud-based solutions enable organizations to securely manage, control, track, search, exchange and collaborate on sensitive information inside and outside the firewall. The total purchase price consideration consisted of the repayment of existing Intralinks indebtedness, and non-cash consideration for services rendered on unvested Intralinks equity awards that were converted into the Company equity awards on the acquisition date. The acquisition was primarily funded from the proceeds of the $900.0 million credit agreement as of the date of acquisition (See Note 7 - Debt for further discussion regarding the credit agreement).

The goodwill acquired is not deductible for tax purposes. Assets Held For Sale Classification In the second quarter of 2017, the Company received a non-binding indication of interest from Siris to acquire the Company and the Company’s Board of Directors decided to explore a broad range of strategic alternatives to a sale of the Company, which included the sale of Intralinks. With the closing of the Intralinks Transaction on November 14, 2017, and as a result of this plan of disposal, the assets and liabilities of Intralinks have been classified as held for sale in our Condensed Consolidated Balance Sheet at June 30, 2017. The Company has also presented the operations of the business as discontinued operations in the Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2017 to provide consistent presentation with our recently filed Form 10-K for the year ended December 31, 2017 and with our subsequent filings of all of the Company’s quarterly reports on Form 10-Q in 2017. The Company’s election to disclose such amounts as held for sale are due to continued reporting delays of this Form 10-Q as part of the Company’s restatement process. 2016 Transactions Openwave Messaging, Inc. (“Openwave”) On March 1, 2016, the Company acquired all outstanding shares of Openwave for $114.5 million , net of working capital adjustments and liabilities assumed, comprised of $92.5 million paid in cash and $22.0 million paid in shares of the Company’s common stock, based upon the average market value of the common stock for the ten trading days prior to the acquisition date. Openwave’s product portfolio includes its core complete messaging platform optimized for today’s most complex messaging requirements worldwide with a particular geographic strength in Asia-Pacific. With this acquisition and combined with Synchronoss’ current global footprint, Synchronoss will have increased direct access to subscribers around the world for the Synchronoss Personal Cloud™ platform and bolster the Company’s go-to-market efforts internationally. In connection with the acquisition of Openwave, the Company entered into $10.0 million patent settlement agreement. The Company determined that the transaction was negotiated in the overall consideration paid for the purchase of Openwave, and as result, the proceeds were reflected as a reduction in the Company’s purchase price. The following is a summary of the components of the consideration transferred as part of the acquisition: (Restated) Cash consideration for outstanding common shares $ 102,538 Issuance of Common Stock 22,000 Intellectual Property Settlement (10,000 ) Total consideration transferred 114,538 Issuance of Common Stock (22,000 ) Cash Consideration Transferred $ 92,538 The Company determined the fair value of the net assets acquired as follows: (Restated) Purchase Price Allocation Cash $ 4,110 Prepaid expenses and other assets 3,005 Property, Plant & Equipment 2,882 Long term assets 1,870 Intangible assets: Wtd.

The goodwill acquired is not deductible for tax purposes. Acquisition-Related Costs Total acquisition-related costs recognized during the six months ended June 30, 2017 and 2016 including transaction costs such as legal, accounting, valuation and other professional services, were $13.0 million and $2.0 million , respectively, and are included in selling, general and administrative expense in the Condensed Consolidated Statements of Operations. Divestitures 2017 Transactions SpeechCycle On February 1, 2017 the Company completed a divestiture of its SpeechCycle business, to an unrelated third party, for consideration of $13.5 million . As part of the divestiture, the Company entered into a one year transition services agreement with the acquiring company to support various indirect activities such as customer software support, technical support services, maintenance and general administrative support services. The Company recorded a pre-tax gain of $4.9 million as a result of the divestiture which is included in other income (expense), net in the Condensed Consolidated Statement of Operations. 2016 Transactions Sequential Technology International, LLC (“STIN”) On December 16, 2016, Synchronoss completed a divestiture of a portion of its business process outsourcing (“BPO”) carrier activation business to a newly formed entity named STIN which had a total value of $140.8 million . As part of the sales arrangement, Synchronoss will retain a 30% investment in STIN. Sequential Technology International Holdings, LLC (“STIH”), an unrelated third party that was formerly named Omniglobe International LLC, will own the remaining 70% of STIN. STIH financed the purchase of these assets through cash of $27.3 million (including $10.0 million of license), a new term loan with Goldman Sachs Bank (“Goldman”), and a related party subordinated seller’s note receivable with a par value of $83.0 million issued by Synchronoss, which is secured by STIH’s interest in STIN. The sellers note was issued at a discount, with a transaction value of $69.8 million . The sellers note earns interest at a rate of LIBO R plus 1100 bps per annum and matures on June 16, 2022. On December 22, 2016, the Company entered into a non-exclusive perpetual license agreement with STIH, for the consideration of $10.0 million . The Company determined that the license agreement was negotiated with the sale, and in the overall consideration paid for the purchase of STIN, and as result, the proceeds from sale of the perpetual license were reflected as additional consideration received from the sale of its BPO business, resulting in additional gain recognized on the sale. Additionally, as part of its divestiture, the Company provided a guarantee to Goldman for $30.0 million of the $40.0 million in senior debt extended by Goldman to STIH which is referenced as the Third Party Note in Note 6 - Investments in Affiliates and Related Transactions . The Company recognized the guarantee on the date of transaction as a reduction in the gain on sale in the amount of $0.6 million . The Company and STIH agreed to a put and call option in regards to the Company’s equity interest in STIN. The Company will have the right to exercise a put option at any time to sell its interest in STIN, at the fair market value determined at the date of exercise. Additionally, STIH will have the right to exercise a call option at any time to purchase the interest in STIN at the fair market value determined at the date of exercise. The Company determined that the put and call options are embedded within the host contract and do not require bifurcation and separate accounting treatment. STIN has been determined to be a VIE of which the Company is not the primary beneficiary. As part of the divestiture, Synchronoss entered into a three -year MSA with STIN to provide for access to certain platforms, and assets necessary to perform certain tasks, as part of the exception handling process. See Note 6 - Investments in Affiliates and Related Transactions . The following is a summary of the operating results of BPO which have been reflected within income from discontinued operations, net of tax: Three Months Ended (Restated) Six Months Ended June 30, 2016 (Restated) Net revenues $ 38,108 $ 74,464 Costs and expenses: Cost of services 23,001 44,859 Selling, general and administrative 718 1,437 Total costs and expenses 23,719 46,296 Income from discontinued operations before taxes 14,389 28,168 Benefit (provision) for income taxes 4,596 (10,369 ) Discontinued operations, net of taxes $ 18,985 $ 17,799 The financial results reflected above may not represent the BPO’s stand-alone operating results, as the results reported within income from discontinued operations, net of tax only include certain costs that are directly attributable to the BPO and exclude certain overhead costs that were previously allocated to the BPO for each period. Mirapoint On December 29, 2016, the Company completed the divestiture of the Company’s Mirapoint business to an unrelated third party and recorded a gain of $1.4 million on the sale, which is included in other income (expense), net in the Condensed Consolidated Statements of Operations. Subsequent Events - Divestiture of Intralinks On June 23, 2017, the Company received a non-binding indication of interest from Siris Capital Group, LLC (“Siris”) to acquire the Company. In light of the indication of interest, the Company’s Board of Directors decided to explore a broad range of strategic alternatives that would have the potential to unlock shareholder value. In October 2017, the Company concluded its review of strategic alternatives and determined that the best approach for the Company to achieve its goal of maximizing shareholder value was to focus on its core Telecommunication, Media and Technology (“TMT”) business, divest non-core assets and improve the Company’s balance sheet strength, cash position and potential profitability. Under the terms of certain definitive agreements, investment funds affiliated with Siris acquired all of the stock of the Company’s wholly-owned subsidiary, Intralinks for consideration of cash and an option for investment in convertible preferred equity of the Company. Subject to the terms and conditions set forth in the Share Purchase Agreement, dated as of October 17, 2017 (the “Share Purchase Agreement”), among Synchronoss, Intralinks and Impala Private Holdings II, LLC, an affiliate of Siris (“Impala”), a related party, due to its significant interest in common stock. Impala agreed to acquire from the Company the issued and outstanding shares of common stock of Intralinks for approximately $977.3 million in cash plus a potential contingent payment of up to $25.0 million , subject to an adjustment for cash, debt and working capital (the “Intralinks Transaction”). The total amount of funds used to complete the Intralinks Transaction and related transactions and pay related fees and expenses was approximately $1.0 billion , which was funded through a combination of equity and debt financing obtained by Impala. Under the terms of the Share Purchase Agreement, the Company also provided Siris with a Siris Put Right (“Siris Put Right”), which would allow Silver to put shares held at the time, to Synchronoss at price of $14.56 per share, or $87.3 million in the aggregate. The Company determined that the Call option on the issuance of preferred and the Siris Put Right, together, represented one mandatorily redeemable financial instrument with a fair value of $33.6 million , which reduced the gain on sale of Intralinks. At the closing of the Intralinks Transaction on November 14, 2017, Impala acquired all of the issued and outstanding shares of Intralinks for approximately $991.0 million in cash, subject to post-closing adjustments for changes in cash, debt and working capital. If, in the future, Impala receives net cash proceeds in excess of $440.0 million from any sale of equity or assets of Intralinks, or a dividend or distribution in respect of the shares of Intralinks, then Impala is required to pay the Company up to an additional $25.0 million in cash or publicly traded securities. Immediately following the consummation of the Intralinks Transaction, the Company paid to Impala $5.0 million as partial reimbursement of the out-of-pocket fees and expenses incurred by Impala, Siris and their respective affiliates in connection with the execution of the Share Purchase Agreement and the Intralinks Transaction. Amounts reimbursed were recorded as a reduction to the gain on sale. In accordance with the terms of the Share Purchase Agreement dated as of October 17, 2017 (the “PIPE Purchase Agreement”), with Silver Private Holdings I, LLC, an affiliate of Siris (“Silver”), on February 15, 2018, we issued to Silver 185,000 shares of our newly issued Series A Convertible Participating Perpetual Preferred Stock (the “Series A Preferred Stock”), par value $0.0001 per share, with an initial liquidation preference of $1,000 per share, in exchange for $97.7 million in cash and the transfer from Silver to us of the 5,994,667 shares of our common stock held by Silver (the “Preferred Transaction”). In connection with the issuance of the Series A Preferred Stock, we (i) filed a Certificate of Designation with the State of Delaware setting forth the rights, preferences, privileges, qualifications, restrictions and limitations on the Series A Preferred Stock (the “Series A Certificate”) and (ii) entered into an Investor Rights Agreement with Silver setting forth certain registration, governance and preemptive rights of Silver with respect to us (the “Investor Rights Agreement”). See Note 9 - Stockholder’s Equity for further discussion. The following is a summary of the operating results of Intralinks during the three and six months ended June 30, 2017 , which have been reflected within income from discontinued operations, net of tax: Three Months Ended Six Months Ended Net revenues $ 64,952 $ 104,211 Costs and expenses: Cost of services 12,040 20,796 Research and development 7,029 12,452 Selling, general and administrative 40,050 69,518 Net change in contingent consideration obligation — — Restructuring charges 7,407 15,433 Depreciation and amortization 12,552 22,690 Total costs and expenses 79,078 140,889 Loss from discontinued operations (14,126 ) (36,678 ) Other income, net 657 927 Loss from discontinued operations, before taxes (13,469 ) (35,751 ) Benefit for income taxes 6,694 12,842 Discontinued operations, net of taxes $ (6,775 ) $ (22,909 ) Subsequent Events - SNCR, LLC During the fourth quarter of 2017, the Company entered into a termination agreement with Goldman to terminate the venture with Goldman, referred to as SNCR, LLC, and provide a perpetual, irrevocable license of the venture’s intellectual property for use in Goldman’s back-office. As part of the agreement, the Company was relieved of any future obligations to support Goldman’s use of the software. As a result, the Company recognized impairment charges of $1.0 million during the fourth quarter of 2017 upon the venture’s termination. The venture formally ended in the first quarter of 2018 resulting in the elimination of the associated redeemable noncontrolling interest balance of the first quarter of 2018, and an increase to Additional Paid In Capital balance of $12.8 million .

Fair Value Disclosures [Abstract]
Fair Value Measurements of Assets and Liabilities	Fair Value Measurements of Assets and Liabilities 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: June 30, 2017 Total (Level 1) (Level 2) (Level 3) Assets Cash, cash equivalents and restricted cash (1) $ 223,138 $ 223,138 $ — $ — Marketable securities-short term (2) 7,165 — 7,165 — Marketable securities-long term (2) 1,193 — 1,193 — Total assets $ 231,496 $ 223,138 $ 8,358 $ — Liabilities Contingent interest derivative (3) $ 288 $ — $ — $ 288 Contingent consideration obligation 2,831 — — 2,831 Total liabilities $ 3,119 $ — $ — $ 3,119 Temporary Equity Redeemable noncontrolling interests (4) $ 25,280 $ — $ — $ 25,280 Total temporary equity $ 25,280 $ — $ — $ 25,280 December 31, 2016 (Restated) Total (Level 1) (Level 2) (Level 3) Assets Cash, cash equivalents and restricted cash (1) $ 211,433 $ 211,433 $ — $ — Marketable securities-short term (2) 12,506 — 12,506 — Marketable securities-long term (2) 2,974 — 2,974 — Total assets $ 226,913 $ 211,433 $ 15,480 $ — Liabilities Contingent consideration obligation $ 2,833 $ — $ — $ 2,833 Total liabilities $ 2,833 $ — $ — $ 2,833 Temporary Equity Redeemable noncontrolling interests (4) $ 25,280 $ — $ — $ 25,280 Total temporary equity $ 25,280 $ — $ — $ 25,280 (1) Cash equivalents primarily included money market funds. (2) Marketable securities is comprised of municipal bonds and certificates of deposit. (3) Contingent interest derivative related to convertible debt is included in accrued expenses, for further details see Note 7 - Debt . (4) Put arrangements held by the noncontrolling interests in certain of the Company’s joint ventures. During the six months ended June 30, 2017, the carrying amount of the redeemable noncontrolling interests was greater than the fair value and accordingly no adjustment to the carrying value was recorded. Available-for-Sale Securities The Company utilizes the market approach to measure fair value for its financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. The Company’s marketable securities investments classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. No transfers between Level 1, Level 2 and Level 3 of the fair value measurement hierarchy occurred during the six months ended June 30, 2017 . Unrealized gains and losses are reported as a component of accumulated other comprehensive income (loss) in stockholders’ equity. There were no sales of marketable securities during the six months ended June 30, 2017 and 2016. The cost of securities sold is based on the specific identification method. The Company evaluates investments with unrealized losses to determine if the losses are other than temporary. The Company has determined that the gross unrealized losses at June 30, 2017 and 2016 are temporary. In making this determination, the Company considered the financial condition, credit ratings and near-term prospects of the issuers, the underlying collateral of the investments, and the magnitude of the losses as compared to the cost and the length of time the investments have been in an unrealized loss position. Additionally, while the Company classifies the securities as available for sale, the Company does not currently intend to sell such investments and it is more likely than not to recover the carrying value prior to being required to sell such investments. At June 30, 2017 and December 31, 2016 , the estimated fair value of investments classified as available-for-sale, were as follows: June 30, 2017 Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Marketable securities: Certificates of deposit 450 — — 450 Municipal bonds 7,914 1 (7 ) 7,908 Total marketable securities $ 8,364 $ 1 $ (7 ) $ 8,358 As of June 30, 2017 , an insignificant amount of accumulated unrealized losses related to investments that have been in a continuous unrealized loss position for 12 months or longer. The aggregate related fair value of investment with unrealized losses was approximately $6.8 million . December 31, 2016 (Restated) Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Marketable securities: Certificates of deposit 450 — — 450 Municipal bonds 15,063 1 (34 ) 15,030 Total marketable securities $ 15,513 $ 1 $ (34 ) $ 15,480 As of December 31, 2016 , an insignificant amount of accumulated unrealized losses related to investments that have been in a continuous unrealized loss position for 12 months or longer. The aggregate related fair value of investment with unrealized losses was approximately $13.8 million . Contractual maturities of marketable debt securities are as follows: June 30, 2017 Amortized Cost Fair Value Due within one year $ 7,169 $ 7,165 Due after 1 year through 5 years 1,195 1,193 Total available-for-sale securities $ 8,364 $ 8,358 Contingent Consideration The Company determined the fair value of the contingent consideration related to the acquisition of Razorsight Corporation (“Razorsight”) using a real options approach which uses a risk-adjusted expected growth rate based on assessments of expected growth in revenue, adjusted by an appropriate factor. The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement. The significant unobservable inputs used in the fair value measurement of the Company’s contingent consideration obligation are the probabilities of achieving certain financial targets and contractual milestones and a risk-adjusted rate of 2.19% . Significant changes in any of those probabilities in isolation may result in a higher (lower) fair value measurement. No changes in valuation techniques occurred during the six months ended June 30, 2017 . The changes in fair value of the Company’s Level 3 contingent consideration obligation during the six months ended June 30, 2017 were as follows: Balance at December 31, 2016 (Restated) $ 2,833 Fair value adjustment to contingent consideration obligation included in net income (2 ) Balance at June 30, 2017 $ 2,831 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. The changes in redeemable noncontrolling interests classified as Level 3 measurements were as follows: Balance at December 31, 2016 (Restated) $ 25,280 Fair value adjustment 5,704 Net loss attributable to interests in subsidiaries (5,704 ) Balance at June 30, 2017 $ 25,280

Equity Method Investments and Joint Ventures [Abstract]
Investments in Affiliates and Related Transactions	Investments in Affiliates and Related Transactions Sequential Technology International, LLC (“STIN”) The Company includes investments which are accounted for using the equity method, under the caption equity method investments on the Company’s Condensed Consolidated Balance Sheets. As of June 30, 2017, the Company’s investments in equity interests was comprised of $44.0 million related to a 30% equity interest in STIN. STIH, which holds a 70% equity interest in STIN, also holds a senior note issued by a Third Party (“Third-Party Note” or “Seller Note”). The Third-Party Note is secured against STIH’s equity interest in STIN and is senior to the Company’s equity interest in STIN. Under the arrangement, the recognition of cash dividends received by the Company from STIN, other than required cash distributions made for tax purposes, are deferred until the Third-Party Note is paid in full. Under the terms of the PIK note with STIH, deferred distributions are added to the amounts outstanding under the PIK note. The Company concluded that STIN is a VIE as it lacks sufficient equity to finance its activities. However, the Company is not the primary beneficiary of STIN, as the Company does not have the power to direct the activities that most significantly impact STIN’s economic performance and the obligation to absorb losses or the right to receive benefits from STIN that could potentially be significant to STIN. The Company regularly reviews its equity investments for impairments based on criteria that include the extent to which the investment’s carrying value exceeds its related market value, the duration of the market decline, the Company’s ability to hold its investment until recovery and the investment’s financial strength and specific prospects. Impairments of investments are reflected in “Equity method income/loss” in the Condensed Consolidated Statements of Operations and were recorded as a result of either the deteriorating financial position of the investee or due to a permanent impairment resulting from sustained losses and limited prospects for recovery. During the first six months of 2017, the Company recorded $1.0 million of equity income in the Condensed Consolidated Statement of Operations related to its investment in STIN. No impairment charges were recognized during the period. Transactions with STIN Cloud Telephony and Support Services In connection with the divestiture of the exception handling business of the Company, Synchronoss entered into a three -year Cloud Telephony and Support services agreement to grant STIN access to certain Synchronoss software and private branch exchange (“PBX”) systems to facilitate exception handling operations required to support STIN customers. The agreement requires the Company provide the following: • Access to use its PBX system, which acts as a digital call exchange used to process both in-bound and out-bound calls as well as any corresponding interactive voice response (“IVR”). • Solution access and hosting, including Synchronoss Activation Gateway (“SAG”) and iNow virtual front office platforms (the “Solution” service) includes access to a number of order managers, call tracker and reporting (visibility) modules used to initiate and perform necessary tasks as part of the exception handling process. Access to the Solution provides a mechanism for the exception handling business, whether STIN or any other BPO customer, to process orders manually. The Company is obligated to host and maintain the related technology throughout the term. In the event additional programs arise, requiring the use of Synchronoss products, such incremental programs will be priced in negotiations at such time. • Technical support service, including network infrastructure support and maintenance. The Company will provide access to use and support to ensure fully operational workstations (including personal computers), including desktop, workstation and network support to the PBX systems, including firewall and anti-virus protection The Company recognized $4.2 million in revenue related to these services during the six months ended June 30, 2017. Support Services Agreement Additionally, the Company entered into a Support Services Agreement (“SSA”) to perform certain general and administrative support services, including billing and cash collections. The SSA is currently operating month-to-month and the Company expects to cease its support within the calendar year. Fees earned for services performed by the Company under the SSA were recorded as a reduction in the costs to perform within selling, general and administrative in the Condensed Consolidated Statements of Operations. Amounts earned under the arrangement were immaterial during all periods presented. Seller Note The Company holds a subordinated seller’s note receivable from STIH which has a carrying value of $82.1 million as of June 30 , 2017 , which is secured by STIH’s interest in STIN. The Company recognized $5.6 million in interest income related to this note during the first six months of 2017. The related party note receivable earns PIK interest at a rate equal to LIBOR plus 1100 basis points per annum and matures on June 16, 2022. As a result, of STIH’s covenant violation, in June 2017, the Company distributed approximately $6.2 million to Goldman (“Distribution Note”). The remaining amounts guaranteed under the arrangement were released upon assignment of certain customer contracts. Under the terms of the PIK note with STIH, distributed amounts made by the Company to Goldman are added to the amounts outstanding under the PIK note. The following is a summary of the PIK note related balances as of June 30, 2017 : Loan Receivable Allowance Unamortized Discount Loan Accrued Interest Distribution Note Distribution Interest Total Balance at December 31, 2016 (Restated) $ 83,000 $ — $ (13,146 ) $ 415 $ — $ — $ 70,269 Activity — — 476 5,135 6,187 32 11,830 Balance at June 30, 2017 $ 83,000 $ — $ (12,670 ) $ 5,550 $ 6,187 $ 32 $ 82,099 Related Party Balances The STIN affiliate balances and their classification in the Condensed Consolidated Balance Sheets as of June 30, 2017 were as follows: Period Ended June 30, 2017 December 31, 2016 (Restated) Restricted cash (A) $ 938 $ — Accounts receivable (B) 17,123 1,164 Total assets $ 18,061 $ 1,164 (A) The Company collected $0.9 million from STI customers, on behalf of STI, which remained outstanding as of June 30, 2017 . This amount has been classified in short term restricted cash and in accrued expenses on the Condensed Consolidated Balance Sheets. (B) These amounts principally included revenues generated from the Cloud and Telephony Support Services agreement and pass-through of vendor expenses incurred during the transition and assignment of vendor contracts.

The 2019 Notes are senior, unsecured obligations of the Company, and are convertible into shares of its common stock based on a conversion rate of 18.8072 shares per $1,000 principal amount of 2019 Notes which is equivalent to an initial conversion price of approximately $53.17 per share. The Company will satisfy any conversion of the 2019 Notes with shares of the Company’s common stock. The 2019 Notes are convertible at the note holders’ option prior to their maturity and if specified corporate transactions occur. The issue price of the 2019 Notes was equal to their face amount. Holders of the 2019 Notes who convert their notes in connection with a qualifying fundamental change, as defined in the related indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, following the occurrence of a fundamental change, holders may require that the Company repurchase some or all of the 2019 Notes for cash at a repurchase price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest, if any. As of June 30, 2017 , none of these conditions existed with respect to the 2019 Notes and as a result, the 2019 Notes are classified as long term. Included in the definition of a fundamental change is whether the Company’s common stock ceases to be listed or quoted on The Nasdaq Stock Market, LLC (“Nasdaq”). In May 2018, trading of the Company’s common stock has been suspended on Nasdaq, however, it has not been delisted (see Note 14 - Subsequent Events Review ). The 2019 Notes are the Company’s direct senior unsecured obligations and rank equal in right of payment to all of the Company’s existing and future unsecured and unsubordinated indebtedness. At June 30, 2017 , the carrying amount of the liability was $227.0 million and the outstanding principal of the 2019 Notes was $230.0 million , with an effective interest rate of approximately 1.38% . The fair value of the 2019 Notes was $217.4 million at June 30, 2017 . The fair value of the liability of the 2019 Notes was determined using a discounted cash flow model based on current market interest rates available to the Company. These inputs are corroborated by observable market data for similar liabilities and therefore classified within Level 2 of the fair-value hierarchy. The Company is required to meet all SEC filing requirements and deadlines in order to be in compliance with the 2019 Notes. In the event that the Company does not meet the filing requirements, the noteholders are entitled to receive additional interest of 0.25% up to 180 days from the date of notice of the default and 0.50% thereafter up to 360 days. The Company may agree to pay additional interest to the holders by notifying holders and the trustee within 90 days from the notice of default. If the Company decides to pay that interest, but has not remedied the event within 360 days from the notice of default, it will be in default. If the Company fails to elect to pay that additional interest, it will be in default if it does not remedy the event within the 90 days period. Interest expense for the Company’s 2019 Notes related to the contractual interest coupon and contingent interest liability is noted below.

Obligations under the 2017 Credit Agreement were guaranteed by certain of the Company’s subsidiaries and secured by substantially all of the Company’s and its subsidiaries’ assets. The 2017 Term Facility amortized at 1% per annum in equal quarterly installments with the balance payable on the maturity date. The Revolving Facility included borrowing capacity available for letters of credit and for borrowings on same-day notice under swingline loans and borrowing thereunder could be used for working capital needs and other general corporate purposes. The 2017 Term Facility initially bear an interest at a rate equal to, at the Company’s option, the adjusted LIBOR rate for an applicable interest period or an alternate base rate, in each case, plus an applicable margin of 2.75% or 1.75% , respectively. The Revolving Facility initially bear an interest at a rate equal to, at the Company’s option, the adjusted LIBOR rate or an alternate base rate, in each case, plus an applicable margin of 2.50% or 1.50% , respectively, subject to step-downs based on the Company’s ratio of first lien secured debt to adjusted EBITDA, as defined in the 2017 Credit Agreement. The Company paid a commitment fee in the range of 0.25% to 0.375% on the unused balance of the Revolving Facility. Interest was payable quarterly under the 2017 Credit Agreement. Subject to certain customary exceptions, the 2017 Term Facility was subject to mandatory prepayments in amounts equal to: (1) 100% of the net cash proceeds from any non-ordinary course sale or other disposition of assets (including as a result of casualty or condemnation) by Synchronoss or its subsidiaries subject to customary reinvestment provisions and certain other exceptions; (2) 100% of the net cash proceeds from incurrences of debt (other than permitted debt); and (3) a customary annual excess cash flow sweep at levels based on the Company’s applicable ratio of first lien secured debt to adjusted EBITDA, as defined in the 2017 Credit Agreement. As of June 30, 2017 , the Company had $1.8 million in outstanding letters of credit issued under the Revolving Facility. The 2017 Term Facility consisted of the following : June 30, 2017 Principal Amount Unamortized Debt Issuance Costs Net Carrying Value Short term portion of the 2017 Term Facility $ 897,750 $ 20,707 $ 877,043 The 2017 Credit Agreement contained a number of customary affirmative and negative covenants and events of default, which, among other things, restricted the Synchronoss’ and its subsidiaries’ ability to incur debt, allow liens on assets, make investments, pay dividends or prepay certain other debt. The 2017 Credit Agreement also required Synchronoss to comply with certain financial maintenance covenants, including a total gross leverage ratio and an interest charge coverage ratio. Certain of the lenders under the 2017 Credit Agreement, or their affiliates, provided, and may in the future from time to time provide, certain commercial and investment banking, financial advisory and other services in the ordinary course of business for the registrant and its affiliates, for which they have in the past and may in the future receive customary fees and commissions. As a result of the Company’s restatement, it was unable to comply with covenants requiring the timely delivery of audited financial statements and interim financial information. The Company obtained waivers to extend the dates by which the Company is required to deliver such financial information to June 30, 2017. Waiver Agreement to 2017 Credit Agreement On June 30, 2017, the Company, the Lenders and the Administrative Agent entered into a Limited Waiver to Credit Agreement (the “Waiver Agreement”) pursuant to which the Lenders agreed, subject to the limitations contained in the Waiver Agreement, to temporarily waive (the “Limited Waiver”) the anticipated event of default (the “Anticipated Event of Default”) resulting from the Company’s failure to deliver its first quarter 2017 financial statements, together with related items required under the 2017 Credit Agreement on or prior to June 30, 2017. In the absence of the Limited Waiver, after the occurrence of the Anticipated Event of Default the Lenders would be permitted to exercise their rights and remedies available to them under the 2017 Credit Facility with respect to an event of default. The Limited Waiver was designed to give the Company and the Lenders additional time to negotiate in good faith and document certain amendments to the 2017 Credit Facility. As consideration for the Limited Waiver, the Company agreed to pay a consent fee to each Lender who consented to the Waiver Agreement in an amount equal to 0.15% of the aggregate principal amount of such consenting Lender’s revolving credit commitments and term loans outstanding under the 2017 Credit Agreement, which amount was credited against any consent fee that was required to be paid in connection with any subsequent waiver of the Anticipated Event of Default or related amendment of the 2017 Credit Agreement. In addition, the Company paid the reasonable fees and expenses of counsel and other costs and expenses requested by the Administrative Agent on behalf of the Lenders and certain other fees as set forth in the Waiver Agreement. As of June 30, 2017 , the Company had $1.8 million in outstanding letters of credit issued under the Revolving Facility. Amended Credit Facility On July 7, 2016, the Company entered into an Amended Credit Facility with Wells Fargo Bank, National Association, as administrative agent and several lenders party thereto (the “Amended Credit Facility”). The Amended Credit Facility, was permitted to be used for general corporate purposes, was a $250.0 million unsecured revolving line of credit that was set to mature on July 7, 2021, subject to terms and conditions set forth therein. The Company paid a commitment fee in the range of 15 to 30 basis points on the unused balance of the revolving credit facility under the Amended Credit Facility. Synchronoss had the right to request an increase in the aggregate principal amount of the Amended Credit Facility up to $350.0 million . Interest on the borrowings ranged from 1.94% to 2.03% . On January 19, 2017, the Company repaid all outstanding obligations under the Amended Credit Facility with Wells Fargo Bank and the several lenders party thereto. The aggregate payoff amount was $29.0 million and included all accrued interest and associated prepayment penalties. The Company paid a commitment fee in the range of 15 to 30 basis points on the unused balance of the revolving credit facility under the Amended Credit Facility. Interest expense and commitment fees under the Credit Facility and the Amended Credit Facility were as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (Restated) (Restated) Commitment fees $ 187 $ 44 $ 359 $ 118 Interest expense 9,288 392 16,660 523 2013 Credit Facility In September 2013, the Company entered into a Credit Facility (the “Credit Facility”) with JP Morgan Chase Bank, N.A., as the administrative agent, Wells Fargo Bank, National Association, as the syndication agent and Capital One, National Association and KeyBank National Association, as co-documentation agents. The Credit Facility, which was used for general corporate purposes, was a $100.0 million unsecured revolving line of credit that was set to mature on September 27, 2018. The Company paid a commitment fee in the range of 25 to 35 basis points on the unused balance of the revolving credit facility under this credit agreement. Synchronoss had the right to request an increase in the aggregate principal amount of the Credit Facility up to $150.0 million . Interest on the borrowing was based upon LIBOR plus a 2.25 basis point margin. All outstanding balances under the Credit Facility were repaid on July 7, 2016 and the 2013 Credit Facility was terminated and replaced with the Amended Credit Facility. Subsequent Event - 2017 Credit Agreement First Amendment to 2017 Credit Agreement On July 19, 2017, the Company entered into a first amendment and limited waiver to the 2017 Credit Agreement (the “First Amendment”). Pursuant to the First Amendment, the lenders and administrative agent agreed to extend the time period for delivery by the Company of its quarterly financial statements for the quarters ended March 31, 2017 and June 30, 2017 (the “2017 Quarterly Financial Statements”) and to waive the default and event of default arising from the Company’s failure to deliver the 2017 Quarterly Financial Statements within the timeframe originally required by the 2017 Credit Agreement (or, at the Company’s election, November 16, 2017, if prior to October 17, 2017 the Company pays a fee to the Lenders equal to 25 basis points on the aggregate principal amount of revolving commitments and term loans outstanding). The First Amendment effected various other changes to the terms of the Credit Agreement, including reducing revolving credit commitments from $200.0 million to $100.0 million (with a sub-limit on usage of $50.0 million until the earliest date by which the Company has delivered the 2017 Quarterly Financial Statements, the restated financial statements for the fiscal years ended December 31, 2016 and 2015 (and the respective quarterly periods) and certain information with respect to disclosing and remedying any material weaknesses in the Company’s internal control structure related to financial reporting). Under the First Amendment, the Company was required to maintain a first lien secured net leverage ratio of no more than (x) 5.50 to 1 for any period ending from September 30, 2017 through March 31, 2019; (y) 5.00 to 1 for any period ending June 30, 2019 through December 31, 2019; and (z) 4.25 to 1 for any period ending March 31, 2020 and thereafter. The Company was also required to maintain a minimum interest coverage ratio of no less than 2.00 to 1. Until the earlier of (A) the later of (i) December 15, 2017 and (ii) in the event that, prior to December 15, 2017, the Company has publicly announced a strategic transaction, or merger, business combination, acquisition or divestiture that would result in a change of control or a requirement to prepay the loans and terminate commitments under the Amended Credit Agreement, the date on which such transaction is consummated or abandoned (the “Initial Period End Date”) and (B) June 15, 2018, term loans under the Amended Credit Agreement bear interest at a rate equal to, at the Company’s option, the adjusted LIBOR rate for an applicable interest period or an alternate base rate (subject to a floor of 1.00% and 2.00% , respectively), in each case, plus an applicable margin of 4.50% or 3.50% , respectively. Thereafter, the applicable margins increase to 5.75% and 4.75% , respectively, if the Company’s first lien secured net leverage ratio is less than or equal to 5.00 to 1, and to 6.75% and 5.75% , respectively, if the Company’s first lien secured net leverage ratio is greater than 5.00 to 1. The foregoing applicable margins are subject to a retroactive increase of 0.25% each if the Restated Financial Statements show an amount of net revenue for any fiscal year ended December 31, 2015, December 31, 2016 and, if applicable, December 31, 2014 that varies by greater than 15% of the net revenue set forth on Consolidated Balance Sheets and related Consolidated Statements of Operations of the Company for such fiscal year that had originally been filed with the Securities and Exchange Commission. Until the Initial Period End Date, revolving loans under the Amended Credit Agreement bear interest at a rate equal to, at Company’s option, the adjusted LIBOR rate or an alternate base rate (subject to a floor of 1.00% and 2.00% , respectively), in each case, plus an applicable margin of 4.50% or 3.50% , respectively. Thereafter, the applicable margins will be subject to step-downs based on the Company’s first lien secured net leverage ratio. Until the Initial Period End Date, term loans under the Amended Credit Agreement are subject to a prepayment premium of 1.00% solely if prepaid with proceeds of a repricing transaction. Thereafter, the term loans will be subject to (x) a 2.00% prepayment premium for any voluntary prepayments (including upon a change of control) made through the one-year anniversary of the Initial Period End Date and (y) a 1.00% prepayment premium for any voluntary prepayments (including upon a change of control) made after the one-year anniversary of the Initial Period End Date and prior to the second anniversary thereof. The Amendment also effected various other changes to the baskets and exceptions under the negative covenants of the Credit Agreement. The Company’s effective interest rate on the term loans was approximately 4.08% prior to the First Amendment and ranged from 5.74% to 5.76% from July 19, 2017 through November 2017. During 2017, the Company paid approximately $16.8 million in fees related to obtaining waivers, amendments, and consents in relation to the 2017 Credit Agreement as a result of the delay in the delivery of the 2017 Quarterly Financial Statements. These costs were recognized within the Interest expense line of the Consolidated Statements of Operations until the debt was repaid in the fourth quarter of 2017. The remaining balance was recognized within the Extinguishment of debt line item of the Consolidated Statements of Operations. Repayment of 2017 Credit Agreement In connection with the consummation of the Intralinks divestiture (See Note 4 - Acquisitions and Divestitures ), the Company utilized a portion of the proceeds from the Intralinks divestiture to repay all outstanding obligations under the 2017 Credit Agreement. In connection therewith, the Company delivered all notices and took all other actions to facilitate and cause the termination of the 2017 Credit Agreement, the repayment in full of all obligations then outstanding thereunder and the release of any security interests in connection therewith, effective as of November 14, 2017. The aggregate payoff amount was approximately $897.5 million and included all accrued interest, fees and prepayment penalties associated therewith.

Subsequent Event - Convertible Senior Notes The Company received a notice of default from holders of more than 25% of the outstanding principal amount of the 2019 Notes on October 13, 2017. Based on the terms of the 2019 Notes, the Company will be obligated to begin paying additional interest starting January 11, 2018 (the 90th day following the Company’s receipt of the notice of default). The Company is required to record a derivative related to this contingent interest as a liability and expense in its financial statements.

Subsequent Events [Abstract]
Subsequent Events Review	Subsequent Events Review For further information about the Company’s significant events subsequent to the period ended June 30, 2017 , 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, 2017. Acquisitions and Divestitures See Note 4 - Acquisitions and Divestitures sub-section, “Subsequent Events-Divestitures”, for a description of subsequent events regarding the Intralinks divestiture during 2017. Debt See Note 7 - Debt for a description of the first amendment to the 2017 Credit Agreement, which became effective July 19, 2017 and the repayment of all outstanding obligations under the 2017 Credit Agreement on November 14, 2017. Nasdaq Compliance and Common Stock The Notice, as discussed in Note 9 - Stockholder’s Equity sub-section, “Subsequent Events - Nasdaq Compliance and Common Stock” indicated that the Company had until July 17, 2017 to submit a plan to regain compliance with Nasdaq’s continued listing requirements. On July 17, 2017, the Company timely submitted its plan to Nasdaq detailing how the Company plans to regain compliance with Nasdaq’s continued listing requirements (the “Compliance Plan”). Nasdaq accepted the Compliance Plan and granted the Company an extension of up to 180 calendar days from the Form 10-Q’s due date, or until November 6, 2017, to regain compliance. On July 26, 2017, the Nasdaq granted the Company an exception from its continued listing requirements until November 13, 2017 to file all delinquent periodic reports, including its delinquent Quarterly Report on Form 10-Q for the period ended March 31, 2017. In connection with its delinquency in filing its Quarterly Report on Form 10-Q for the period ended June 30, 2017, Nasdaq has requested an update to the Company’s original plan to regain compliance with Nasdaq’s continued listing requirements. On August 16, 2017, the Company received notice from the Nasdaq indicating that the Company was not in compliance with the Rule because the Company has not yet filed its Quarterly Report on Form 10-Q for the period ended June 30, 2017. On November 15, 2017, the Company received a letter from the Staff of the Nasdaq notifying the Company that since it remains delinquent in filing its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2017, June 30, 2017 and September 30, 2017, it has not regained compliance with the Rule, which requires timely filing of periodic reports with the Securities and Exchange Commission (the “SEC”). Previously, Nasdaq granted the Company an extension until November 13, 2017 to file all delinquent periodic reports. As described in the letter, as a result of the continued delinquency, the Company’s common stock is subject to delisting unless the Company timely requests a hearing before a Nasdaq Hearings Panel (the “Panel”). On December 6, 2017 the Company received a letter from the Hearings Department of the Nasdaq granting the Company’s request to extend the stay of suspension pending a hearing before the Panel, in late January 2018, and issuance of a final Panel decision. On February 6, 2018, the Company received a notification letter from a Hearings Advisor from the Nasdaq Office of General Counsel informing the Company that the Panel granted the Company’s request for an extension until May 10, 2018 to become current with its filings with the SEC. Additionally, the extension was subject to the Company providing the Panel with periodic updates regarding its ongoing restatement of its financial statements and providing the Panel with an update issued to investors on or before March 31, 2018. The Panel granted the Company the maximum possible extension until the expiration of the Panel’s discretion to allow continued listing while the Company remained out of compliance with Nasdaq’s continued listing requirements. To comply with the Nasdaq extension requirements, the Company issued an update to investors on March 28, 2018. On May 4, 2018, the Company informed the Panel of its determination that it would be unable to satisfy the May 10, 2018 deadline. On May 11, 2018, the Company received a notification letter from the Panel indicating that trading in the Company’s common stock was suspended effective at the open of business on May 14, 2018. The Panel also determined to delist the Company’s shares from Nasdaq after applicable appeal periods have lapsed. The Company has appealed the decision to the Nasdaq Listing and Hearing Review Council. During the appeal process, the Company’s stock remains listed however trading in the Company’s common stock on Nasdaq remains suspended. While the Company’s common stock is suspended from trading on Nasdaq, the Company’s shares are currently quoted on the OTC Markets under the trading symbol SNCR. Share Purchase Agreement See Note 9 - Stockholder’s Equity sub-section “Subsequent Event - Share Purchase Agreement” for a description of subsequent events regarding the Share Purchase Agreement that resulted in the Intralinks divestiture during 2017. Shares of Preferred Stock See Note 9 - Stockholder’s Equity sub-section “Subsequent Events - Shares of Preferred Stock” for a description of the terms of the PIPE Purchase Agreement with Silver on February 15, 2018, in which the Company issued Series A Preferred Stock. Acquisition of honeybee In May 2018, the Company completed the acquisition of the honeybee software business, a provider of digital solutions targeted at optimizing the customer experience from Dixons Carphone plc. honeybee offers a digital transformation platform that makes it easier for companies to design and launch omni-channel customer journeys. The Company paid cash consideration of approximately $10.7 million . Customers of the honeybee platform, such as mobile operators and other communication service providers, can rapidly create and adapt digital sales processes for contact centers, retail stores, and online channels. This reduces complexity for the end-user as well as internal employees, while delivering a single customer experience at all touch-points and improved business outcomes such as reduced cost and increased revenue. 2019 Notes Notice On June 13, 2018, The Bank of New York Mellon, in its capacity as trustee (the “Trustee”) under the indenture dated as of August 12, 2014 (the “Indenture”) governing the Company’s 0.75% Convertible Senior Notes due in 2019 (the “2019 Notes”), filed a verified complaint with the Court of Chancery of the State of Delaware, captioned The Bank of New York Mellon, as Indenture Trustee v. Synchronoss Technologies, Inc. (the “BNY Action”). The BNY Action complaint alleges that as a result of our common stock ceasing to be listed or quoted on Nasdaq and that an Event of Default under the Indenture has occurred as a result of our failure to provide a notice of such Fundamental Change, which, if true, following notice from holders of more than 25% of the outstanding principal under the Notes would trigger the acceleration of the principal and interest outstanding under the 2019 Notes. The complaint seeks a declaratory judgment that (i) a Fundamental Change occurred, (ii) the Company improperly failed to issue a Fundamental Change Company Notice (as defined in the Indenture), (iii) an Event of Default has occurred (as defined in the Indenture), (iv) the Notes have been accelerated, (v) outstanding principal and outstanding unpaid interest on the Notes became immediately due and payable as of June 11, 2018 and (vi) post-judgment interest shall accrue at the statutory rate from the date of declaratory judgment. The Company does not believe that a Fundamental Change has occurred under the Indenture. Therefore, the Company does not believe that any Event of Default, as defined in the Indenture, has occurred or is continuing and does not believe that the Trustee or any holders have a right to declare obligations under the Indenture due and payable. As such, the Company believes that the asserted claims lack merit, and the Company intends to defend against all of the claims vigorously. Due to the inherent uncertainties of litigation, the Company cannot predict the outcome of the BNY Action at this time, and the Company can give no assurance that the asserted claims will not have a material adverse effect on the Company’s financial position or results of operations.

Stock-Based Compensation The following table summarizes stock-based compensation expense related to all of the Company’s stock awards included in operating expense categories, as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (Restated) (Restated) Cost of revenues $ 471 $ 1,362 $ 2,208 $ 2,916 Research and development 953 2,032 2,980 3,811 Selling, general and administrative 1,214 4,294 5,561 8,751 Total stock-based compensation expense $ 2,638 $ 7,688 $ 10,749 $ 15,478 The following table summarizes information about stock-based compensation: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (Restated) (Restated) Stock options $ 1,535 $ 2,209 $ 2,988 $ 3,968 Restricted stock awards 1,036 5,283 7,431 11,060 Employee Stock Purchase Plan 67 196 330 450 Total stock-based compensation before taxes $ 2,638 $ 7,688 $ 10,749 $ 15,478 Tax benefit $ 506 $ 2,655 $ 1,713 $ 5,363 The total stock-based compensation cost related to unvested equity awards as of June 30, 2017 was approximately $59.2 million . The expense is expected to be recognized over a weighted-average period of approximately 2.54 years. As part of the work force reduction driven by corporate restructuring initiated in 2016, the Company terminated certain employees in 2017 and accelerated the vesting of certain unvested restricted stock awards and stock options for these employees. The Company accounted for the acceleration of these awards as a result of the restructuring termination as a Type III modification under ASC Topic 718 and recorded an incremental expense of $1.1 million over the new requisite service period. Replacement Awards On January 19, 2017, certain equity awards granted under the Intralinks 2010 Equity Incentive Plan and the Intralinks 2007 Stock Option and Grant Plan (together, the “Intralinks Plans”) were assumed by the Company’s 2015 Plan. The assumed awards are subject to the vesting and service conditions of the 2015 Plan. Subsequently, these were accelerated as part of the Intralinks Transaction. Please see Note 4 - Acquisitions and Divestitures for more information on the transaction. Among the equity awards assumed were restricted stock units subject to market-based performance targets in order for them to vest. Vesting is subject to continued service requirements through the vesting date. The grant date fair value for such unvested restricted stock units was estimated using a Monte Carlo simulation that incorporates option-pricing inputs covering the period from the grant date through the end of the performance period. Stock-based compensation expense for such unvested restricted stock units is recognized on a straight-line basis over the vesting period, regardless of whether the market condition is satisfied. All of these awards were canceled in the second and third quarter of 2017 pursuant to termination of related employees. Stock Options There were no significant changes to the Company’s Stock Option Plans during the six months ended June 30, 2017. The Company uses the Black-Scholes option pricing model for determining the estimated fair value for stock options. The weighted-average assumptions used in the Black-Scholes option pricing model are as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (Restated) (Restated) Expected stock price volatility 53.2 % 43.6 % 49.2 % 43.4 % Risk-free interest rate 1.7 % 1.2 % 1.7 % 1.2 % Expected life of options (in years) 4.05 4.00 4.03 4.00 Expected dividend yield — % — % — % — % Weighted-average fair value (grant date) of the options $ 6.87 $ 12.49 $ 7.79 $ 11.07 The following table summarizes information about stock options outstanding: Options Number of Options Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at December 31, 2016 (Restated) 2,306 $ 32.43 Options Granted 1,380 20.61 Options Exercised (104 ) 23.68 Options Cancelled (440 ) 30.74 Outstanding at June 30, 2017 3,142 $ 27.76 3.89 $ 597 Vested and expected to vest June 30, 2017 3,073 $ 27.66 3.87 $ 597 Vested and exercisable at June 30, 2017 1,287 $ 31.75 2.96 $ 24 The below table summarizes additional information related to the Company’s awards for the three and six months ended June 30, 2017: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (Restated) (Restated) Total intrinsic value for stock options exercised $ 11 $ 1,780 $ 1,007 $ 3,639 Awards of Restricted Stock and Performance Stock There were no significant changes to the Company’s restricted stock award (“Restricted Stock”) and performance stock plan during the six months ended June 30, 2017. A summary of the Company’s non-vested restricted stock at June 30, 2017 , and changes during the six months ended June 30, 2017 , is presented below: Non-Vested Restricted Stock Number of Awards Weighted- Average Grant Date Fair Value Non-vested at December 31, 2016 (Restated) 1,645 $ 36.27 Granted 1,798 21.45 Vested (702 ) 32.34 Forfeited (491 ) 28.15 Non-vested at June 30, 2017 2,250 $ 27.43 Restricted stock awards are granted subject to other service conditions or service and performance conditions (“Performance-Based Awards”). Restricted stock and performance-based awards are measured at the closing stock price at the date of grant and are recognized straight line over the requisite service period. During 2017, the Company issued 43,413 shares of restricted stock related to the 2016 performance objectives. Of the 2,250,503 non-vested restricted awards and units outstanding under the 2015 Plan as of June 30, 2017, 560,691 awards represents the forecasted number of awards whereby vesting is contingent on meeting certain performance conditions based on Revenue and EBITDA for the Company with an average grant date price of $23.49 . Employee Stock Purchase Plan On February 1, 2012, the Company established a ten year Employee Stock Purchase Plan (“ESPP” or “the Plan”) for certain eligible employees. The Plan is administered by the Company’s Board of Directors. The total number of shares available for purchase under the Plan is 500 thousand shares of the Company’s common stock. Employees participate over a six month period through payroll withholdings and may purchase, at the end of the six month period, the Company’s common stock at the lower of 85% of the fair market value on the first day of the offering period or the fair market value on the purchase date. No participant will be granted a right to purchase common stock under the Plan if such participant would own more than 5% of the total combined voting power of the Company. In addition, no participant may purchase more than a thousand shares of common stock within any purchase period or with a value greater than $25 thousand in any calendar year. The Plan was indefinitely suspended on July 27, 2017. Share Repurchase Program On February 4, 2016, the Company announced that our Board of Directors approved a share repurchase program under which we may repurchase up to $100.0 million of our outstanding common stock for 12 to 18 months following the announcement. In 2016, the Company repurchased approximately 1.3 million shares of the Company’s common stock under this program for an aggregate repurchase price of $40.0 million . There were no repurchases during the six months ended June 30, 2017. Subsequent Event - Share Purchase Agreement As of October 16, 2017, investment funds affiliated with Siris owned 5,994,667 shares (the “Existing Siris Shares”) of Synchronoss’ common stock, par value $0.0001 per share (the “Common Stock”) as of such date . On October 17, 2017, the Company announced the entry into definitive agreements for the sale of Intralinks and the right to purchase a newly created series of preferred stock of Synchronoss to affiliates of Siris. Subject to the terms and conditions set forth in the Share Purchase Agreement, dated as of October 17, 2017 (the “Share Purchase Agreement”), among Synchronoss, Intralinks and Impala, Impala agreed to complete the Intralinks Transaction. Please see Note 4 - Acquisitions and Divestitures for more information on the transaction. At the closing of the Intralinks Transaction on November 14, 2017, Impala acquired all of the issued and outstanding shares of Intralinks for approximately $991.0 million in cash, subject to post-closing adjustments for changes in cash, debt and working capital. If, in the future, Impala receives net cash proceeds in excess of $440.0 million from any sale of equity or assets of Intralinks, or a dividend or distribution in respect of the shares of Intralinks, then Impala is required to pay the Company up to an additional $25.0 million in cash or publicly traded securities. Immediately following the consummation of the Intralinks Transaction, the Company paid to Impala $5.0 million as partial reimbursement of the out-of-pocket fees and expenses incurred by Impala, Siris and their respective affiliates in connection with the execution of the Share Purchase Agreement and the Intralinks Transaction. As of November 14, 2017, investment funds affiliated with Siris owned 5,994,667 shares of the Company’s common stock as of such date. In addition, subject to the terms and conditions set forth in the PIPE Purchase Agreement, between Synchronoss and Silver, Synchronoss agreed to issue an option to sell to Silver 185,000 shares of Series A Preferred Stock in the Preferred Transaction. Prior to or contemporaneously with the consummation of the Preferred Transaction, Synchronoss agreed to file the Series A Certificate and enter into the Investor Rights Agreement with Silver setting forth certain registration, governance and preemptive rights of Silver with respect to Synchronoss discussed below. Subsequent Event - Stock Plans During 2017, the Company’s Board of Directors approved the issuance of market-based restricted stock to certain executives which are eligible to vest if the volume-weighted average closing price over 20 consecutive trading days equals or exceeds certain stock prices during the specific performance period from July 2017 to July 2019. The Company utilized the Monte Carlo simulation to estimate the fair value of the restricted stock on its grant date. In connection with the appointment a new Chief Executive Officer in November 2017, the Company entered into an employment agreement which provided for the grant of restricted stock awards, stock options and performance stock awards. These awards were approved by the Compensation Committee of Synchronoss’ Board of Directors and granted as an inducement equity award outside the 2015 Plan in accordance with the Nasdaq Listing Rule 5635(c)(4) (the “Inducement Rule”). Subsequent Event - Shares of Preferred Stock In accordance with the terms of the PIPE Purchase Agreement, with Silver, on February 15, 2018, the Company exercised its option to complete the Preferred Transaction. In connection with the issuance of the Series A Preferred Stock, the Company (i) filed the Series A Certificate and (ii) entered into the Investor Rights Agreement. Pursuant to the PIPE Purchase Agreement, at the closing, the Company paid to Siris $5.0 million as a reimbursement of Silver’s reasonable costs and expenses incurred in connection with the Preferred Transaction. Certificate of Designation of the Series A Preferred Stock The rights, preferences, privileges, qualifications, restrictions and limitations of the shares of Series A Preferred Stock are set forth in the Series A Certificate. Under the Series A Certificate, the holders of the Series A Preferred Stock are entitled to receive, on each share of Series A Preferred Stock on a quarterly basis, an amount equal to the dividend rate of 14.5% divided by four and multiplied by the then-applicable Liquidation Preference (as defined in the Series A Certificate) per share of Series A Preferred Stock (collectively, the “Preferred Dividends”). The Preferred Dividends are due on January 1, April 1, July 1 and October 1 of each year (each, a “Series A Dividend Payment Date”). The Company may choose to pay the Preferred Dividends in cash or in additional shares of Series A Preferred Stock. In the event the Company does not declare and pay a dividend in-kind or in cash on any Series A Dividend Payment Date, the unpaid amount of the Preferred Dividend will be added to the Liquidation Preference. In addition, the Series A Preferred Stock participates in dividends declared and paid on shares of the Company’s common stock. Each share of Series A Preferred Stock is convertible, at the option of the holder, into the number of shares of common stock equal to the “Conversion Price” (as that term is defined in the Series A Certificate) multiplied by the then applicable “Conversion Rate” (as that term is defined in the Series A Certificate). Each share of Series A Preferred Stock is initially convertible into 55.5556 shares of common stock, representing an initial “conversion price” of approximately $18.00 per share of common stock. The Conversion Rate is subject to equitable proportionate adjustment in the event of stock splits, recapitalizations and other events set forth in the Series A Certificate. On and after the fifth anniversary of February 15, 2018, holders of shares of Series A Preferred Stock have the right to cause the Company to redeem each share of Series A Preferred Stock for cash in an amount equal to the sum of the current liquidation preference and any accrued dividends. Each share of Series A Preferred Stock is also redeemable at the option of the holder upon the occurrence of a “Fundamental Change” (as that term is defined in the Series A Certificate) at a specified premium. In addition, the Company is also permitted to redeem all outstanding shares of the Series A Preferred Stock at any time (i) within the first 30 months of the date of issuance for the sum of the then-applicable Liquidation Preference, accrued but unpaid dividends and a make whole amount and (ii) following the 30 -month anniversary of the date of issuance for the sum of the then-applicable Liquidation Preference and the accrued but unpaid dividends. The holders of a majority of the Series A Preferred Stock, voting separately as a class, are entitled at each of the Company’s annual meetings of stockholders or at any special meeting called for the purpose of electing directors (or by written consent signed by the holders of a majority of the then-outstanding shares of Series A Preferred Stock in lieu of such a meeting): (i) to nominate and elect two members of the Company’s Board of Directors for so long as the Preferred Percentage (as defined in the Series A Certificate) is equal to or greater than 10% ; and (ii) to nominate and elect one member of the Company’s Board of Directors for so long as the Preferred Percentage is equal to or greater than 5% but less than 10% . For so long as the holders of shares of Series A Preferred Stock have the right to nominate at least one director, the Company is required to obtain the prior approval of Silver prior to taking certain actions, including: (i) certain dividends, repayments and redemptions; (ii) any amendment to the Company’s certificate of incorporation that adversely effects the rights, preferences, privileges or voting powers of the Series A Preferred Stock; (iii) issuances of stock ranking senior or equivalent to shares of Series A Preferred Stock (including additional shares of Series A Preferred Stock) in the priority of payment of dividends or in the distribution of assets upon any liquidation, dissolution or winding up of us; (iv) changes in the size of the Company’s Board of Directors; (v) any amendment, alteration, modification or repeal of the charter of the Company’s Nominating and Corporate Governance Committee of the Board of Directors and related documents; and (vi) any change in the Company’s principal business or the entry into any line of business outside of the Company’s existing lines of businesses. In addition, in the event that the Company is in EBITDA Non-Compliance (as defined in the Series A Certificate) or the undertaking of certain actions would result in the Company exceeding a specified pro forma leverage ratio, then the prior approval of Silver would be required to incur indebtedness (or alter any debt document) in excess of $10.0 million , enter or consummate any transaction where the fair market value exceeds $5.0 million individually or $10.0 million in the aggregate in a fiscal year or authorize or commit to capital expenditures in excess of $25.0 million in a fiscal year. Each holder of Series A Preferred Stock has one vote per share on any matter on which holders of Series A Preferred Stock are entitled to vote separately as a class, whether at a meeting or by written consent. The holders of Series A Preferred Stock are permitted to take any action or consent to any action with respect to such rights without a meeting by delivering a consent in writing or electronic transmission of the holders of the Series A Preferred Stock entitled to cast not less than the minimum number of votes that would be necessary to authorize, take or consent to such action at a meeting of stockholders. In addition to any vote (or action taken by written consent) of the holders of the shares of Series A Preferred Stock as a separate class provided for in the Series A Certificate or by the General Corporation Law of the State of Delaware, the holders of shares of the Series A Preferred Stock are entitled to vote with the holders of shares of common stock (and any other class or series that may similarly be entitled to vote on an as-converted basis with the holders of common stock) on all matters submitted to a vote or to the consent of the stockholders of the Company (including the election of directors) as one class. Under the Series A Certificate, if Silver and certain of its affiliates have elected to effect a conversion of some or all of their shares of Series A Preferred Stock and if the sum, without duplication, of (i) the aggregate number of shares of the Company’s common stock issued to such holders upon such conversion and any shares of the Company’s common stock previously issued to such holders upon conversion of Series A Preferred Stock and then held by such holders, plus (ii) the number of shares of the Company’s common stock underlying shares of Series A Preferred Stock that would be held at such time by such holders (after giving effect to such conversion), would exceed the 19.9% of the issued and outstanding shares of the Company’s voting stock on an as converted basis (the “Conversion Cap”), then such holders would only be entitled to convert such number of shares as would result in the sum of clauses (i) and (ii) (after giving effect to such conversion) being equal to the Conversion Cap (after giving effect to any such limitation on conversion). Any shares of Series A Preferred Stock which a holder has elected to convert but which, by reason of the previous sentence, are not so converted, will be treated as if the holder had not made such election to convert and such shares of Series A Preferred Stock will remain outstanding. Also, under the Series A Certificate, if the sum, without duplication, of (i) the aggregate voting power of the shares previously issued to Silver and certain of its affiliates held by such holders at the record date, plus (ii) the aggregate voting power of the shares of Series A Preferred Stock held by such holders as of such record date, would exceed 19.99% of the total voting power of the Company’s outstanding voting stock at such record date, then, with respect to such shares, Silver and certain of its affiliates are only entitled to cast a number of votes equal to 19.99% of such total voting power. The limitation on conversion and voting ceases to apply upon receipt of the requisite approval of holders of the Company’s common stock under the applicable listing standards. Form of Investor Rights Agreement Concurrently with the closing of the Preferred Transaction, Synchronoss and Silver entered into an Investor Rights Agreement. Under the terms of the Investor Rights Agreement, Silver and Synchronoss have agreed that, effective as of the closing of the Preferred Transaction, the Board of Directors of Synchronoss will consist of ten members. From and after the closing of the Preferred Transaction, so long as the holders of Series A Preferred Stock have the right to nominate a member to the Board of Directors pursuant to the Series A Certificate, the Board of Directors of Synchronoss will consist of (i) two directors nominated and elected by the holders of shares of Series A Preferred Stock; (ii) four directors who meet the independence criteria set forth in the applicable listing standards (each of whom will be initially agreed upon by Synchronoss and Silver); and (iii) four other directors, two of whom shall satisfy the independence criteria of the applicable listing standards and, as of the closing of the Preferred Transaction, one of whom shall be the individual then serving as chief executive officer of Synchronoss and one of whom shall be the current chairman of the Board of Directors of Synchronoss as of the date of execution of the Investors Rights Agreement. Following the closing of the Preferred Transaction, so long as the holders of Series A Preferred Stock have the right to nominate at least one director to the Board of Directors of Synchronoss pursuant to the Series A Certificate, Silver will have the right to designate two members of the Nominating and Corporate Governance Committee of the Board of Directors. Pursuant to the terms of the Investor Rights Agreement, neither Silver nor its affiliates may transfer any shares of Series A Preferred Stock subject to certain exceptions (including transfers to affiliates that agree to be bound by the terms of the Investor Rights Agreement). For so long as Silver has the right to appoint a director to the Board of Directors of Synchronoss, without the prior approval by a majority of directors voting who are not appointed by the holders of shares of Series A Preferred Stock, neither Silver nor its affiliates will directly or indirectly purchase or acquire any debt or equity securities of Synchronoss (including equity-linked derivative securities) if such purchase or acquisition would result in Silver’s Standstill Percentage (as defined in the Investor Rights Agreement) being in excess of 30% . However, the foregoing standstill restrictions would not prohibit the purchase of shares pursuant to the PIPE Purchase Agreement or the receipt of shares of Series A Preferred Stock issued as Preferred Dividends pursuant to the Series A Certificate, shares of Common Stock received upon conversion of shares of Series A Preferred Stock or receipt of any shares of Series A Preferred Stock, Common Stock or other securities of the Company otherwise paid as dividends or as an increase of the Liquidation Preference (as defined in the Series A Certificate) or distributions thereon. Silver will also have preemptive rights with respect to issuances of securities of Synchronoss in order to maintain its ownership percentage. Under the terms of the Investor Rights Agreement, Silver will be entitled to (i) three demand registrations, with no more than two demand registrations in any single calendar year and provided that each demand registration must include at least 10% of the shares of Common Stock held by Silver, including shares of Common Stock issuable upon conversion of shares of Series A Preferred Stock and (ii) unlimited piggyback registration rights with respect to primary issuances and all other issuances. Subsequent Events - Common Stock On November 15, 2017, the Company received a letter from the Staff of the Nasdaq notifying the Company that since it remains delinquent in filing its Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2017, June 30, 2017 and September 30, 2017, it has not regained compliance with the Rule, which requires timely filing of periodic reports with the Securities and Exchange Commission (the “SEC”). Previously, Nasdaq granted the Company an extension until November 13, 2017 to file all delinquent periodic reports. As described in the letter, as a result of the continued delinquency, the Company’s common stock is subject to delisting unless the Company timely requests a hearing before a Nasdaq Hearings Panel (the “Panel”). On December 6, 2017, the Company received a letter from the Hearings Department of the Nasdaq granting the Company’s request to extend the stay of suspension pending a hearing before the Panel, in late January 2018, and issuance of a final Panel decision. On February 6, 2018, the Company received a notification letter from a Hearings Advisor from the Nasdaq Office of General Counsel informing the Company that the Nasdaq Hearings Panel (the “Panel”) granted the Company’s request for an extension until May 10, 2018 to become current with its filings with the SEC. Additionally, the extension was subject to the Company providing the Panel with periodic updates regarding its ongoing restatement of its financial statements and providing the Panel with an update issued to investors on or before March 31, 2018. The Panel granted the Company the maximum possible extension until the expiration of the Panel’s discretion to allow continued listing while the Company remained out of compliance with Nasdaq’s continued listing requirements. To comply with the Nasdaq extension requirements, the Company issued an update to investors on March 28, 2018. On May 4, 2018, the Company informed the Panel of its determination that it would be unable to satisfy the May 10, 2018 deadline. On May 11, 2018, the Company received a notification letter from the Panel indicating that trading in the Company’s common stock was suspended effective at the open of business on May 14, 2018. The Panel also determined to delist the Company’s shares from Nasdaq after applicable appeal periods have lapsed. The Company has appealed the decision to the Nasdaq Listing and Hearing Review Council. During the appeal process, the Company’s stock remains listed however trading in the Company’s common stock on Nasdaq remains suspended. While the Company’s common stock is suspended from trading on Nasdaq, the Company’s shares are currently quoted on the OTC Markets under the trading symbol SNCR.

Income Taxes	Income Taxes The Company recognized approximately $5.1 million and $15.2 million in related income tax benefit during the six months ended June 30, 2017 and 2016 , respectively. The effective tax rate was approximately 7.0% for the six months ended June 30, 2017 , which was lower than our U.S. federal statutory rate primarily due to the unfavorable impact of losses in foreign jurisdictions which have lower tax rates than the U.S. Our effective tax rate was approximately 25.0% for the six months ended June 30, 2016, which was lower than our U.S. federal statutory rate primarily due to the unfavorable impact of losses in foreign jurisdictions which have lower tax rates than the U.S. We review the expected annual effective income tax rate and make changes on a quarterly basis as necessary based on certain factors such as changes in forecasted annual operating income, changes to the actual and forecasted permanent book-to-tax differences, and changes resulting from the impact of tax law changes.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Other	Commitments, Contingencies and Other 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. Guarantee As part of its divestiture of its activation exception handling business in 2016, the Company provided a guarantee to Goldman for $30.0 million of the $40.0 million in senior debt extended by Goldman to STIH which is referenced as the Third Party Note in Note 6 - Investments in Affiliates and Related Transactions . At March 31, 2017, STIH missed its minimum earnings before interest, tax, depreciation and amortization (“EBITDA”) target under the Goldman loan. As a result of STIH’s covenant violation, in June 2017, the Company distributed approximately $6.2 million to Goldman as previously defined, the Distribution Note. The remaining amounts guaranteed under the arrangement were released upon assignment of certain customer contracts during the first quarter. Under the terms of the PIK note with STIH, distributed amounts made by the Company to Goldman are added to the amounts outstanding under the PIK note. As of June 30, 2017, the Company has no further obligations to guarantee the debt outstanding to Goldman. Legal Matters On October 7, 2014, the Company filed an amended complaint in the United States District Court for the District of New Jersey (Civ Act. No. 3:14-cv-06220) against F-Secure Corporation and F-Secure, Inc. (collectively, “F-Secure”), claiming that F-Secure has infringed, and continues to infringe, several of the Company’s patents. In February 2015, the Company entered into a patent license and settlement agreement with F-Secure Corporation and F-Secure, Inc. whereby the Company granted each of these companies (but not their subsidiaries or affiliates) a limited license to our patents. As a result of entering into the patent license and settlement agreement, the parties filed a joint stipulation to dismiss the above complaint. Subsequent Event - Legal Matters On May 1, 2017, May 2, 2017, June 8, 2017 and June 14, 2017, four putative class actions were filed against the Company and certain of its officers and directors in the United States District Court for the District of New Jersey (the “Securities Law Action”). After these cases were consolidated, the court appointed as lead plaintiff Employees’ Retirement System of the State of Hawaii, which filed, on November 20, 2017, a consolidated amended complaint purportedly on behalf of purchasers of our common stock between February 3, 2016 and June 13, 2017. The consolidated amended complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and it alleges, among other things, that the defendants made false and misleading statements of material information concerning the Company’s financial results, business operations, and prospects. The plaintiff seeks unspecified damages, fees, interest, and costs. On February 2, 2018, the defendants filed a motion to dismiss the consolidated amended complaint in its entirety, with prejudice, which remains pending. We believe that the asserted claims lack merit, and we intend to defend against all of the claims vigorously. Due to the inherent uncertainties of litigation, we cannot predict the outcome of the actions at this time, and we can give no assurance that the asserted claims will not have a material adverse effect on our financial position or results of operations. On September 15, 2017, October 24, 2017, October 27, 2017 and October 30, 2017, Synchronoss shareholders filed derivative lawsuits against certain of the Company’s officers and directors and the Company (as nominal defendant) in the United States District Court for the District of New Jersey (the “Derivative Suits”). These lawsuits purport to allege claims related to breaches of fiduciary duties and unjust enrichment. The allegations in the Derivative Suits relate to substantially the same facts as those underlying the Securities Law Action described above. The plaintiffs seek unspecified damages and for the Company to take steps to improve its corporate governance and internal procedures. The plaintiffs in the Derivative Suits in which service of the complaints was effectuated have agreed to stay proceedings pending the court’s decision on the defendants’ motion to dismiss in the Securities Laws Action. The Company believes that the asserted claims lack merit, and we intend to defend against all of the claims vigorously. Due to the inherent uncertainties of litigation, the Company cannot predict the outcome of the Derivative Suits at this time, and the Company can give no assurance that the asserted claims will not have a material adverse effect on the Company’s financial position or results of operations. Our 2011 acquisition agreement with Miyowa SA (“Miyowa”) provided that former shareholders of Miyowa would be eligible for earn-out payments to the extent specified business milestones were achieved following the acquisition. In December 2013, Eurowebfund and Bakamar, two former shareholders of Miyowa filed a complaint against the Company in the Commercial Court of Paris, France claiming that they are entitled to certain earn-out payments under the acquisition agreement. The Company was served with a copy of this complaint in January 2014. On December 3, 2015, the Court dismissed all claims in the complaint against the Company. On December 19, 2015, the former shareholders of Miyowa filed an appeal with the Court of Appeal of Paris, France, appealing the Court’s decision. On January 11, 2018, the Court of Appeal of Paris, France, dismissed the appeal. The plaintiffs have informed us that they will not be appealing this decision. On July 11, 2017, Shareholder Representative Services LLC, on behalf of the persons entitled to receive merger consideration (the “Sellers”) in connection with our acquisition of Razorsight, commenced arbitration against us with respect to a dispute over the amount due to the Sellers as additional consideration. Under the Razorsight purchase agreement, the Sellers are entitled to a percentage of any revenue recognized by us generated from the sale or licensing of Razorsight products in 2016 after a specific revenue threshold is obtained. The parties disagreed over the determination of the amount of revenue we recognized in 2016. The parties entered into an agreement resolving the arbitration in May 2018. Except as set forth above, the Company is not currently subject to any legal proceedings that could have a material adverse effect on its operations; however, it may from time to time become a party to various legal proceedings arising in the ordinary course of its business. The Company is currently the plaintiff in several patent infringement cases. The defendants in several of these cases have filed counterclaims. Although the Company cannot predict the outcome of the cases at this time due to the inherent uncertainties of litigation, the Company continues to pursue its claims and believes that the counterclaims are without merit, and the Company intends to defend all of such counterclaims.

Basis of Presentation and Consolidation	The condensed consolidated financial statements as of June 30, 2017 and for the three and six months ended June 30, 2017 and 2016 are unaudited, but in the opinion of management, include all adjustments (consisting only of normal recurring 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 for 2017 and 2016 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, as they have been filed prior to this quarterly report on Form 10-Q and certain prior year amounts have been restated. Refer to Note 3 - Restatement of Previously Issued Consolidated Financial Statements and Note 14 - Subsequent Events Review for background on the restatement of previously issued financial statements and Nasdaq compliance, respectively. The results of operations for the three and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ended December 31, 2017 .

Recently Issued and Adopted Accounting Standards	Recently Issued Accounting Standards Recent accounting pronouncements adopted Standard Description Effect on the financial statements ASU 2017-04 Simplifying the Test for Goodwill Impairment In January 2017, the Financial Accounting Standards Board (“FASB”) issued guidance which eliminates Step 2 from the goodwill impairment test. Under the amendments in this Update, an entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Accounting Standard Update (“ASU”) 2017-04 also eliminates the requirement for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. ASU 2017-04 is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company elected to early adopt this ASU for annual and interim goodwill impairment testing dates after January 1, 2017. The adoption of this ASU had no impact on the Company’s consolidated financial statements. Date of adoption: January 1, 2020. Standard Description Effect on the financial statements ASU 2017-01 Business Combinations (Topic 805), Clarifying the Definition of a Business In January 2017, FASB changed its definition of a business in an effort to help entities determine whether a set of transferred assets and activities is a business. The guidance requires an entity to first evaluate whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of transferred assets and activities is not a business. If the threshold is not met, the entity evaluates whether the set meets the requirement that a business include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance narrows the definition of outputs by more closely aligning it with how outputs are described in the new revenue guidance. The guidance is effective for public business entities for annual periods beginning after 15 December 2017, and interim periods within those periods. For all other entities, it is effective for annual periods beginning after 15 December 2018, and interim periods within annual periods beginning after 15 December 2019. Early adoption is permitted. The Company adopted this ASU on January 1, 2017 on a prospective basis. The adoption of this ASU had no impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. ASU 2016-18 Statement of Cash Flows (Topic 230) In November 2016, the FASB issued ASU 2016-18, which amends the guidance in ASC 230, including providing additional guidance related to transfers between cash and restricted cash and how entities present, in their statement of cash flows, the cash receipts and cash payments that directly affect the restricted cash accounts. ASU 2016-18 is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those years, with early adoption permitted. The Company adopted this ASU on January 1, 2017 to each period presented and applied the changes to the condensed consolidated statements of cash flows. Date of adoption: January 1, 2017. ASU 2016-17 Consolidation: Interest Held through Related Parties That Are under Common Control In October 2016, the FASB issued ASU 2016-17, to amend the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity should treat indirect interests in the entity held through related parties that are under common control within the reporting entity when determining whether it is the primary beneficiary of that variable interest entity. The standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted this ASU on January 1, 2017 on a prospective basis. The adoption of this ASU had no significant impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. ASU 2016-16 Intra-Entity Transfers of Assets Other Than Inventory In October 2016, the FASB issued ASU 2016-16, which requires entities to recognize at the transaction date the income tax effects for intra-entity transfers of assets other than inventory. The standard is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this ASU on January 1, 2017 on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings of $3.2 million as of January 1, 2017. Date of adoption: January 1, 2017. ASU 2016-15 Statement of Cash Flows In August 2016, the FASB issued ASU 2016-15 which will make eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017. ASU 2016-15 will require adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable. The Company adopted this ASU on January 1, 2017 using a retrospective transition method. The adoption of this ASU had no impact on the Company’s condensed consolidated financial statements. Date of adoption: January 1, 2017. Standards issued not yet adopted Standard Description Effect on the financial statements ASU 2017-09 Stock Compensation (Topic 718), Scope of Modification Accounting In May 2017, FASB issued guidance which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Entities will apply the modification accounting guidance if the value, vesting conditions or classification of the award changes. The guidance also clarifies that a modification to an award could be significant and therefore require disclosure, even if modification accounting is not required. ASU 2017-09 is effective for fiscal years, and interim periods within those years, beginning after December 31, 2017. Early adoption is permitted as of the beginning of an annual period for which financial statements have not been issued. ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date. The Company is currently evaluating the impact of the adoption of this ASU on its condensed consolidated financial statements. Date of adoption: January 1, 2018. ASU 2016-13 Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13 which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The ASU is effective for public companies in annual periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted beginning after December 15, 2018 and interim periods within those years. The Company is currently evaluating the impact of the adoption of this ASU on its condensed consolidated financial statements. Date of adoption: January 1, 2020. ASU 2016-02 Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02 which requires lessees to recognize, for all leases of 12 months or more, a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset for the lease term. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature of an entity’s leasing activities. This ASU is effective for public reporting companies for interim and annual periods beginning after December 15, 2018, with early adoption permitted, and must be adopted using a modified retrospective approach. The Company is in the process of evaluating the effect of the new guidance on its condensed consolidated financial statements and disclosures. Date of adoption: January 1, 2019. In May 2014, the FASB issued a new accounting standard related to revenue recognition, ASU 2014-09, “Revenue from Contracts with Customers,” (“ASC 606” or “Topic 606”). The new standard supersedes the existing revenue recognition requirements under U.S. GAAP and requires entities to recognize revenue when they transfer control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. It also requires increased disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows arising from contracts with customers. On January 1, 2018, we adopted Topic 606 applying the modified retrospective method to all contracts that were not completed as of January 1, 2018. We recorded a net reduction to opening retained earnings of approximately $10.1 million as of January 1, 2018 due to the cumulative impact of adopting Topic 606. The impact of adoption primarily relates to (1) the delayed pattern of recognition under Topic 606 for certain professional services revenue when such professional services involve the customization of features and functionality for subscription services customers and (2) the earlier pattern of recognition under Topic 606 for license revenue when the Company provides hosting services for on-premise license customers. In the case of professional services that involve the customization of features and functionality for subscription services, under historic accounting policies the professional services were considered to have standalone value, and as a result were recognized as the services were performed. Under Topic 606, such professional services are not considered to be a distinct performance obligation within the context of the subscription services contract, and as such customization services revenue is recognized over the shorter of the estimated remaining life of the subscription software (typically three years) or the remaining term of the subscription services contract. In the case of license contracts sold in association with hosting, under historic accounting policies the license revenue was recognized over the hosting term due to the lack of vendor specific objective evidence (“VSOE”) of fair value for the hosting services. Under Topic 606, VSOE is no longer required in order to allocate revenue between the license and the hosting services, and the license revenue is generally recognized upon delivery of the software based on the relative allocation of the contract price based on the established standalone selling price (“SSP”) Additional impacts of adoption include (1) in certain cases changes in the amount allocated to the various performance obligation in accordance with the relative standalone selling price method required by Topic 606 compared to the amount allocated to the various elements in accordance with the residual method or the relative selling price method, as applicable, under historic accounting policies, (2) the capitalization and subsequent amortization of certain sales commissions as costs to obtain a contract under ASC 340-40, whereas under historic accounting policies all such amounts were expensed as incurred (3) the timing and amount of revenue recognition for certain sales contracts that are considered to involve variable consideration under Topic 606, but were considered to either not be fixed or determinable or to involve contingent revenue features under historic accounting policies, (4) in certain limited cases, the accounting for discounted customer options to purchase future software or services as material rights under Topic 606, as well as (5) the income tax impact of the above items, as applicable. In connection with the adoption of Topic 606 and the related cost accounting guidance under ASC 340, we are required to capitalize certain contract acquisition costs consisting primarily of commissions and bonuses paid when contracts are signed. As of January 1, 2018, the date we adopted Topic 606, we capitalized $0.7 million in contract acquisition costs related to contracts that were not completed.
Fair Value Measurements of Assets and Liabilities	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.
