Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Consolidation Unaudited Interim Condensed Consolidated Financial Statements 10-K, Use of Estimates Marketable Securities available-for-sale Revenue Recognition — Revenue from the Company’s premium services is recognized on a daily basis over the subscription term as the services are delivered, provided that there is persuasive evidence of an arrangement, the fee is fixed or determinable and collectability is deemed reasonably assured. Subscription periods range from monthly to ten years. The Company’s software cannot be run on another entity’s hardware and customers do not have the right to take possession of the software and use it on their own or another entity’s hardware. Revenue from the Company’s audio services is recognized upon actual usage of audio minutes or the expiration of audio minutes purchased in prepaid plans. Any unbilled audio revenue is accrued for in the period the usage occurs. The Company’s multi-element arrangements typically include subscription and professional services, which may include development services. The Company evaluates each element within the arrangement to determine if they can be accounted for as separate units of accounting. If the delivered item or items have value to the customer on a standalone basis, either because they are sold separately by any vendor or the customer could resell the delivered item or items on a standalone basis, the Company has determined that the deliverables within these arrangements qualify for treatment as separate units of accounting. Accordingly, the Company recognizes revenue for each delivered item or items as a separate earnings process commencing when all of the significant performance obligations have been performed and when all of the revenue recognition criteria have been met. Professional services revenue recognized as a separate earnings process under multi-element arrangements has been immaterial to date. In cases where the Company has determined that the delivered items within its multi-element arrangements do not have value to the customer on a stand-alone basis, the arrangement is accounted for as a single unit of accounting and the related consideration is recognized ratably over the estimated customer life, commencing when all of the significant performance obligations have been delivered and when all of the revenue recognition criteria have been met. Revenue from these multi-element arrangements has been immaterial to date. Concentrations of Credit Risk and Significant Customers For the three and nine months ended September 30, 2016 and 2017, no customers accounted for more than 10% of revenue. As of December 31, 2016 and September 30, 2017, no customers accounted for more than 10% of accounts receivable. Goodwill Long-Lived Assets and Intangible Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets, including intangible assets, may not be recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there is impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. Through September 30, 2017, the Company recorded no material impairments. Foreign Currency Translation — period-end Derivative Financial Instruments — As of September 30, 2017, the Company had outstanding forward contracts with notional amounts equivalent to the following (in thousands): Currency Hedged September 30, U.S. Dollar / Canadian Dollar $ 401 Euro / U.S. Dollar 3,600 Euro / British Pound 2,011 Israeli Shekel / Hungarian Forint (1) 7,850 Total $ 13,862 (1) The Israeli Shekel and Hungarian Forint forward contract covers an intercompany loan between Nanorep Technologies Ltd. (“Nanorep”) and the Company’s Hungarian subsidiary. Nanorep was acquired in the third quarter of 2017. For additional information regarding the acquisition, see Note 4. The Company had net foreign currency losses of $0.2 million and $0.7 million for the three and nine months ended September 30, 2016, respectively, a net foreign currency gain of $47,000 for the three months ended September 30, 2017 and a net foreign currency loss of $28,000 for the nine months ended September 30, 2017, which are included in other income (expense), net in the condensed consolidated statements of operations. Stock-Based Compensation — Income Taxes The Company evaluates its uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings is more likely than not to be realized. Potential interest and penalties associated with any uncertain tax positions are recorded as a component of income tax expense. Segment Data The Company’s revenue by geography (based on customer address) is as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2017 2016 2017 Revenues: United States $ 60,713 $ 204,831 $ 177,440 $ 545,117 United Kingdom 6,530 13,371 19,239 37,318 International—all other 17,860 51,065 51,424 131,315 Total revenue $ 85,103 $ 269,267 $ 248,103 $ 713,750 Amounts for the three and nine months ended September 30, 2016 presented in the Company’s revenue by service cloud (product grouping) table below include reclassifications between product groups to conform to the current year classification of the Company’s products (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2017 2016 2017 Revenues: Communications and Collaboration cloud $ 10,413 $ 146,808 $ 29,622 $ 377,780 Identity and Access Management cloud 50,352 76,380 144,483 208,487 Customer Engagement and Support cloud 24,338 46,079 73,998 127,483 Total revenue $ 85,103 $ 269,267 $ 248,103 $ 713,750 Guarantees and Indemnification Obligations — by-laws. In the ordinary course of business, the Company enters into agreements with certain customers that contractually obligate the Company to provide indemnifications of varying scope and terms with respect to certain matters including, but not limited to, losses arising out of the breach of such agreements, from the services provided by the Company or claims alleging that the Company’s products infringe third-party patents, copyrights, or trademarks. The term of these indemnification obligations is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these indemnification obligations is, in many cases, unlimited. Through September 30, 2017, the Company has not experienced any losses related to these indemnification obligations. Net Income (Loss) Per Share — The Company excluded the following options to purchase common shares and restricted stock units from the computation of diluted net loss per share because they had an anti-dilutive impact (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2017 2016 2017 Options to purchase common shares 418 — — — Restricted stock units 1,473 36 106 59 Total options and restricted stock units 1,891 36 106 59 Basic and diluted net income (loss) per share was calculated as follows (in thousands, except per share data): Three months ended September 30, Nine months ended September 30, 2016 2017 2016 2017 Basic: Net income (loss) $ (657 ) $ 9,920 $ 776 $ 6,202 Weighted average common shares outstanding, basic 25,401 52,706 25,230 49,697 Net income (loss) per share, basic $ (0.03 ) $ 0.19 $ 0.03 $ 0.12 Diluted: Net income (loss) $ (657 ) $ 9,920 $ 776 $ 6,202 Weighted average common shares outstanding 25,401 52,706 25,230 49,697 Add: Common stock equivalents — 900 779 1,038 Weighted average common shares outstanding, diluted 25,401 53,606 26,009 50,735 Net income (loss) per share, diluted $ (0.03 ) $ 0.19 $ 0.03 $ 0.12 Recently Adopted Accounting Pronouncements On May 10, 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09 Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting 2017-09”), 2017-09 On January 1, 2017, the Company adopted ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting 2016-09”) paid-in paid-in Further, upon the adoption of ASU 2016-09, On January 1, 2017, the Company early adopted ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory 2016-16”) Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers The Company plans to adopt ASC 606 using the modified retrospective transition method which will result in an adjustment to retained earnings for the cumulative effect of applying the standard to all contracts not completed as of the adoption date. As this adoption method does not result in a recast of the prior year financial statements, ASC 606 requires the Company to provide additional disclosures during the year of adoption of the amount by which each financial statement line item is affected by adoption of the new standard and explanation of the reasons for significant changes. The Company is currently evaluating the impact of the adoption of ASC 606 to its consolidated financial statements, accounting policies, IT systems and processes. The Company has allocated internal and external resources to assist in its implementation and evaluation of the impact of ASC 606 and has made enhancements to its financial information systems to assist in financial reporting under ASC 606. While the Company cannot reliably estimate the expected financial statement impact at this time, the Company expects the revenue recognition of its primary revenue streams to remain substantially unchanged and therefore, does not expect a material impact on its revenues upon adoption of ASC 606. The adoption of ASC 606 will have an impact on the Company's consolidated financial statements with respect to its accounting for sales commissions related to customer arrangements. In making this determination the Company has also considered the impact of the guidance in ASC 340-40, Other Assets and Deferred Costs; Contracts with Customers 2014-09 340-40”). 340-40, On February 25, 2016, the FASB issued ASU 2016-02, Leases 2016-02”) , right-of-use 2016-02 right-of-use On January 26, 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment 2017-04”), 2017-04 2017-04 On November 17, 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB’s EITF) 2016-18”). 2016-18 2016-18

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	3. Fair Value of Financial Instruments The carrying value of the Company’s financial instruments, including cash equivalents, restricted cash, accounts receivable and accounts payable, approximate their fair values due to their short maturities. The Company’s financial assets and liabilities are measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows: • Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company at the measurement date. • Level 2: Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following table summarizes the basis used to measure certain of the Company’s financial assets that are carried at fair value (in thousands): Fair Value Measurements at December 31, 2016 Level 1 Level 2 Level 3 Total Cash equivalents — money market funds $ 11,599 $ — $ — $ 11,599 Short-term marketable securities: U.S. government agency securities 34,961 8,001 — 42,962 Corporate bond securities — 12,748 — 12,748 Fair Value Measurements at September 30, 2017 Level 1 Level 2 Level 3 Total Cash equivalents — money market funds $ 166,918 $ — $ — $ 166,918 Short-term marketable securities: U.S. government agency securities 7,997 — — 7,997 Corporate bond securities — 5,999 — 5,999 Forward contracts — 13 — 13 Bank deposits, corporate bonds and certain U.S. government agency securities are classified within the second level of the fair value hierarchy as the fair value of those assets are determined based upon quoted prices for similar assets.

Acquisitions	4. Acquisitions Acquisition-Related Costs Acquisition-related costs were $16.9 million and $51.4 million for the nine months ended September 30, 2016 and 2017, respectively. Acquisition-related costs are associated with the acquisitions of businesses and intellectual property and include transaction, transition and integration-related charges (including legal, accounting and other professional fees, severance, and retention bonuses) and subsequent adjustments to our initial estimated amount of contingent consideration associated with acquisitions. Acquisition-related costs for the nine months ended September 30, 2016 were primarily comprised of $9.8 million of acquisition-related costs associated with the Merger and $6.7 million of retention bonuses related to the Company’s 2014 and 2015 acquisitions. Acquisition-related costs for the nine months ended September 30, 2017 were primarily related to the Merger and consisted of $26.2 million in transaction, transition and integration-related expenses, $10.1 million in integration-related severance costs and $15.1 million of retention-based bonuses, of which $9.7 million was related to the Merger. 2017 Acquisitions Nanorep Technologies Ltd. On July 31, 2017, the Company, through its wholly-owned Hungarian subsidiary, acquired all of the outstanding equity interests in Nanorep Technologies Ltd. (“Nanorep”), an Israeli provider of artificial intelligence, chatbot and virtual assistant services, for $43.4 million, net of cash acquired. Additionally, the Company expects to pay up to $5 million in cash in the future to certain employees of Nanorep contingent upon their continued service over the two-year The acquisition is being accounted for under the acquisition method of accounting. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The preliminary determination of the fair value of assets acquired and liabilities assumed has been recognized based on management’s estimates and assumptions using the information about facts and circumstances that existed at the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The Company expects to finalize the allocation of purchase price in the fourth quarter of 2017. The following table summarizes the Company’s preliminary purchase price allocation (in thousands): Cash $ 923 Accounts receivable 1,108 Property and equipment 78 Restricted cash 129 Prepaid expenses and other current assets 334 Intangible assets: Completed technology 9,200 Customer relationships 10,500 Trade name 500 Deferred revenue (854 ) Accounts payable and accrued liabilities (2,704 ) Deferred tax liabilities, net (1,977 ) Goodwill 27,062 Total purchase consideration 44,299 Less: cash acquired 923 Total purchase consideration, net of cash acquired $ 43,376 The useful lives of the identifiable intangible assets acquired range from 8 to 10 years with a weighted average useful life of 9.1 years. The goodwill recorded in connection with this transaction is primarily related to the expected synergies to be achieved as a result of the Company’s ability to leverage its customer base, sales force and business plan with Nanorep’s product, technical expertise and customer base. All goodwill and intangible assets acquired are not deductible for income tax purposes. The Company recorded a long-term deferred tax asset of $2.9 million primarily related to net operating losses that were acquired as a part of the acquisition and a long-term deferred tax liability of $4.8 million primarily related to the amortization of intangible assets which cannot be deducted for tax purposes, resulting in a net long-term deferred tax liability of $2.0 million. GetGo Merger On January 31, 2017, the Company completed its Merger with GetGo, a wholly-owned subsidiary of Citrix, pursuant to which the Company acquired Citrix’s GoTo Business. In connection with the Merger, the Company issued 26.9 million shares of its common stock to Citrix stockholders and an additional 0.4 million of the Company’s restricted stock units in substitution for certain outstanding Citrix restricted stock units held by GetGo employees. Based on the Company’s closing stock price of $108.10 on January 31, 2017 as reported by the NASDAQ Global Select Market, the total value of the shares of LogMeIn common stock issued to Citrix stockholders in connection with the Merger was $2.9 billion. In the third quarter of 2017, pursuant to the terms of the merger agreement, the Company accrued $3.3 million of additional purchase price for final adjustments related to defined targets for cash and cash equivalents and non-cash The Merger is being accounted for under the acquisition method of accounting with the operations of the GoTo Business included in the Company’s operating results since the date of acquisition. During the nine months ended September 30, 2017, the Company recorded revenue of $439.9 million, amortization of acquired intangibles of $119.8 million and acquisition-related transaction, transition and integration costs of $41.5 million directly attributable to the Merger within its condensed consolidated financial statements. Since the Merger, the operating costs of the GoTo Business have been integrated with the operating costs of the Company and therefore, the Company has not provided operating income for the GoTo Business. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The preliminary determination of the fair value of assets acquired and liabilities assumed has been recognized based on management’s estimates and assumptions using the information about facts and circumstances that existed at the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The finalization of the purchase accounting assessment will result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company’s results of operations and financial position. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill to reflect additional information received about facts and circumstances that existed at the date of acquisition. The Company records these adjustments to the assets acquired and liabilities assumed subsequent to the purchase price allocation period in the Company’s operating results in the period in which the adjustments were determined. The size and breadth of the Merger necessitates the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the fair value of certain tangible and intangible assets acquired and liabilities assumed as of the acquisition date and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below. The Company expects to record additional adjustments related to tax balances and tax attributes in the fourth quarter of 2017 as the GetGo entities finalize their tax returns for fiscal year 2016. The following table summarizes the fair value (in thousands) of the assets acquired and liabilities assumed at the date of acquisition: Purchase consideration: Company common shares issued $ 2,904,487 (1) Restricted stock units issued 16,692 (2) Cash consideration payable 3,317 (3) Total estimated purchase consideration $ 2,924,496 Estimated fair value of assets acquired and liabilities assumed: Cash 24,215 Accounts receivable 48,957 (4) Property and equipment 59,715 Prepaid expense and other current assets 22,986 (4) Other assets 4,448 Intangible assets (weighted average useful life): (5) Completed technology (9 years) 385,000 Customer relationships (8 years) 756,000 Tradenames and trademark (9 years) 65,100 Accounts payable (11,030 ) Accrued liabilities (26,886 ) Deferred revenue, current and noncurrent (82,643 ) Other long-term liabilities (996 ) Deferred tax liability, net (426,081 ) Goodwill $ 2,105,711 (1) Represents the fair value of the 26.9 million new shares of the Company’s common stock (plus cash in lieu of fractional shares) issued to Citrix stockholders, based on the fair value per share of the Company’s common stock of $108.10 per share, which was the closing price of the Company’s common stock on the NASDAQ Global Select Market on January 31, 2017. (2) Represents the fair value of the 0.4 million restricted stock units issued by the Company in substitution for certain outstanding Citrix restricted stock units held by GetGo employees, pursuant to the terms of the Merger. These Company restricted stock units were issued on the same terms and conditions as were applicable to the outstanding Citrix restricted stock units held by the GetGo employees immediately prior to the Merger date (including the same vesting and forfeiture provisions). The aggregate fair value of those awards ($48.2 million) is based on the fair value per share of the Company’s common stock of $108.10 per share, which was the closing price of the Company’s common stock on the NASDAQ Global Select Market on January 31, 2017. Of that amount, $18.0 million was related to pre-combination (3) Represents $3.3 million of additional purchase price paid by the Company to Citrix, pursuant to the terms of the merger agreement for final adjustments related to defined targets for cash and cash equivalents and non-cash (4) During the nine months ended September 30, 2017, the Company identified measurement period adjustments that impacted the estimated fair value of the assets and liabilities assumed as of the date of the acquisition. The table above, which summarizes the allocation of the purchase price for the entities acquired, has been updated to reflect these measurement period adjustments. The total measurement period adjustments resulted in a decrease in accounts receivable of $1.1 million, an increase in prepaid expense and other current assets of $1.2 million and a decrease in goodwill of $0.1 million. This change to the provisional fair value amounts of the assets and liabilities assumed had no impact on the Company’s results of operations for the nine months ended September 30, 2017. (5) The weighted average useful life of identifiable intangible assets acquired in the Merger is 8.4 years. The completion of the Merger and the acquisition of the GoTo Business has resulted in a combined company with the scale, employees, products and customer base needed to lead large markets, support a more global customer base and compete against a variety of different solution providers of all sizes. Goodwill of $2.1 billion was recognized for the excess purchase consideration over the estimated fair value of the assets acquired. Goodwill and intangible assets recorded as part of the acquisition are not deductible for tax purposes. The Company recorded a deferred tax liability, net of deferred tax assets, of $426.1 million, which was primarily related to the amortization of intangible assets which cannot be deducted for tax purposes and which was partially offset by deferred tax assets primarily related to the pre-combination The Company and Citrix entered into a transition services agreement, pursuant to which each party will provide to the other party certain services on a transitional basis following the completion of the Merger to facilitate the transition of the GoTo Business to the Company. Among other services, the transition services generally relate to information technology and security operations, facilities, human resources support and accounting and finance support. As of September 30, 2017, the Company has incurred $4.9 million of costs related to the transition services agreement. The unaudited financial information in the table below summarizes the combined results of operations for the Company and the GoTo Business, on a pro forma basis, as though the Merger had been consummated as of the beginning of 2016, including amortization charges from acquired intangible assets, the effect of acquisition accounting on the fair value of acquired deferred revenue, the inclusion of expense related to retention-based bonuses assuming full achievement of the retention requirements, the reclassification of all acquisition-related costs incurred by the Company and the GoTo Business as of the beginning of 2016 through the first quarter of 2017 (the quarter the Merger was completed), and the related tax effects. The second and third quarter of 2017 reported results of the Company have not been adjusted.

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes The Company recorded a provision for federal, state, and foreign taxes of $0.1 million and a benefit of $2.6 million on a loss before income taxes of $0.6 million and a profit before income taxes of $7.3 million for the three months ended September 30, 2016 and 2017, respectively. For the nine months ended September 30, 2016 and 2017, the Company recorded a provision for federal, state, and foreign taxes of $0.4 million and a benefit of $33.1 million on a profit before income taxes of $1.2 million and a loss before income taxes of $26.9 million, respectively. The effective income tax rates for the nine months ended September 30, 2016 and 2017 were impacted by profits earned in certain foreign jurisdictions, primarily our Irish subsidiaries, which are subject to significantly lower tax rates than the U.S. federal statutory rate. The effective income tax rate for the nine months ended September 30, 2017 was also impacted by the expected non-deductibility 2016-09 Deferred tax assets, related valuation allowances, current tax liabilities and deferred tax liabilities are determined separately by tax jurisdiction. In making these determinations, the Company estimates deferred tax assets, current tax liabilities and deferred tax liabilities, and the Company assesses temporary differences resulting from differing treatment of items for tax and accounting purposes. As of September 30, 2017, the Company maintained a full valuation allowance against the deferred tax assets of its Hungarian subsidiary. This entity has historical tax losses and the Company concluded it was not more likely than not that these deferred tax assets are realizable. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company’s income tax returns are open to examination by federal, state, and/or foreign tax authorities. The United States federal income tax returns are open to examination from 2014. In the normal course of business, the Company and its subsidiaries are examined by various taxing authorities. The Company regularly assesses the likelihood of additional assessments by tax authorities and provides for these matters as appropriate. Audits by tax authorities typically involve examination of the deductibility of certain permanent items, limitations on net operating losses and tax credits. Although the Company believes its tax estimates are appropriate, the final determination of tax audits could result in material changes in its estimates. The Company has recorded a liability related to uncertain tax positions of $1.5 million and $4.1 million as of December 31, 2016 and September 30, 2017, respectively. The Company’s policy is to record estimated interest and penalties related to the underpayment of income taxes or unrecognized tax benefits as a component of its income tax provision. The Company recognized $21,000 and $31,000 of interest expense for the nine months ended September 30, 2016 and 2017, respectively.

During the third quarter, the Company paid a cash dividend of $0.25 per share on August 25, 2017 to stockholders of record as of August 9, 2017. The Company’s Board of Directors will continue to review this capital return plan for potential modifications based on the Company’s financial performance, business outlook and other considerations. The timing and number of shares to be repurchased pursuant to the capital return plan will depend upon prevailing market conditions and other factors related to the Merger. Additionally, the Company’s credit facility contains certain financial and operating covenants that may restrict its ability to pay dividends in the future. For the three months ended September 30, 2016 and 2017, the Company repurchased 45,562 and 191,618 shares of its common stock at an average price of $75.98 and $111.99 per share, for a total cost of $3.5 million and $21.5 million, respectively.

Stock Incentive Plan	9. Stock Incentive Plan The Company’s 2009 Stock Incentive Plan (“2009 Plan”) is administered by the Board of Directors and Compensation Committee, which have the authority to designate participants and determine the number and type of awards to be granted and any other terms or conditions of the awards. The Company awards restricted stock units as the principal equity incentive award. Restricted stock units with time-based vesting conditions generally vest over a three-year period while restricted stock units with market-based or performance-based vesting conditions generally vest over two or three-year periods. Until 2012, the Company generally granted stock options as the principal equity incentive award. Options generally vest over a four-year period and expire ten years from the date of grant. Certain stock-based awards provide for accelerated vesting if the Company experiences a change in control. Effective on January 31, 2017, the Company’s stockholders approved an amendment and restatement of the Company’s 2009 Stock Incentive Plan, which increased the number of shares of the Company’s common stock that may be issued under the plan by an additional 4.5 million shares and extended the term of the plan to December 5, 2026. As of September 30, 2017, 7.1 million shares remained available for grant under the 2009 Plan. The following table summarizes stock option activity (shares and intrinsic value in thousands): Number of Options Weighted Average Weighted Average Aggregate Outstanding, January 1, 2017 355 $ 33.15 5.0 $ 22,529 Granted — — Exercised (175 ) 36.41 $ 11,373 Forfeited (1 ) 26.57 Outstanding, September 30, 2017 179 $ 30.02 3.9 $ 14,336 The aggregate intrinsic value was calculated based on the positive differences between the fair value of the Company’s common stock of $96.55 per share on December 31, 2016 and $110.05 per share on September 30, 2017, or at time of exercise, and the exercise price of the options. As of September 30, 2017, the Company had 170,388 shares exercisable. During the nine months ended September 30, 2017, the Company granted 1,283,531 restricted stock units, of which 1,165,378 have time-based vesting conditions, 81,915 have performance-based vesting conditions and 36,238 have market-based vesting conditions. Restricted stock units with time-based vesting conditions are valued on the grant date using the grant date closing price of the underlying shares. The Company recognizes the expense on a straight-line basis over the requisite service period of the restricted stock unit, which is generally three years. The performance-based awards vest on February 14, 2019 based on the achievement of performance criteria for fiscal years 2017 and 2018 established by the Board of Directors at the time of grant. Shares not earned will be forfeited. Since 2013, the Company has granted to certain key executives restricted stock unit awards with market-based vesting conditions, which are tied to the individual executive’s continued employment with the Company throughout the applicable performance period and the level of the Company’s achievement of a pre-established two-year The following table summarizes restricted stock unit activity, including market-based TSR Units (shares in thousands): Number of shares Weighted Average Unvested as of January 1, 2017 1,445 $ 62.23 Restricted stock units granted 837 108.29 Restricted stock units issued for Merger 446 108.10 Restricted stock units earned 66 Restricted stock units vested (848 ) 70.17 Restricted stock units forfeited (175 ) 81.24 Unvested as of September 30, 2017 1,771 $ 90.42 The Company recognized stock based compensation expense within the accompanying condensed consolidated statements of operations as summarized in the following table (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2017 2016 2017 Cost of revenue $ 536 $ 1,612 $ 1,774 $ 3,911 Research and development 1,476 6,405 4,702 16,042 Sales and marketing 4,398 4,312 12,876 12,108 General and administrative 2,589 6,436 7,975 17,194 $ 8,999 $ 18,765 $ 27,327 $ 49,255 On January 1, 2017, the Company adopted ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting 2016-09”)

For the purposes of comprehensive income disclosures, the Company does not record tax provisions or benefits for the net changes in the foreign currency translation adjustment, as the Company intends to reinvest permanently undistributed earnings of its foreign subsidiaries. Accumulated other comprehensive income (loss) is reported as a component of stockholders’ equity and, as of December 31, 2016 and September 30, 2017, was comprised of cumulative translation adjustment losses of $6.6 million and gains of $10.8 million and unrealized losses (net of tax) on marketable securities of $16,000 and $7,000, respectively.

Credit Facility	12. Credit Facility On February 1, 2017, the Company entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”), which increased the Company’s secured revolving credit facility from $150 million to $400 million in the aggregate, and permits the Company to increase the revolving credit facility and/or enter into one or more tranches of term loans up to an additional $200 million. The Amended Credit Agreement also extended the maturity date of the revolving credit facility to February 1, 2022. The Company may prepay the loans or terminate or reduce the commitments in whole or in part at any time, without premium or penalty. The Company and its subsidiaries expect to use the credit facility for general corporate purposes, including, but not limited to, the potential acquisition of complementary products or businesses, share repurchases, as well as for working capital. The Company repaid $30.0 million of borrowings in the second quarter of 2017. There was no outstanding debt balance as of September 30, 2017. Loans under the Amended Credit Agreement bear interest at variable rates which reset every 30 to 180 days depending on the rate and period selected by the Company as described below. The average interest rate on borrowings outstanding during the nine month period ending September 30, 2017 was 2.188%. The quarterly commitment fee on the undrawn portion of the credit facility ranges from 0.15% to 0.30% per annum, based upon the Company’s total leverage ratio. The Amended Credit Agreement contains customary affirmative and negative covenants, subject to customary and other exceptions for a credit facility of this size and type, each as further described in the Amended Credit Agreement. As of September 30, 2017, the Company was in compliance with all financial and operating covenants of the Amended Credit Agreement. Any failure to comply with the financial or operating covenants of the Amended Credit Agreement would prevent the Company from being able to borrow additional funds, and would constitute a default, permitting the lenders to, among other things, accelerate the amounts outstanding, including all accrued interest and unpaid fees, under the credit facility and to terminate the credit facility. As of September 30, 2017, the Company had $2.4 million of origination costs recorded in other assets. The Company incurred approximately $2.0 million of origination costs in connection with the Amended Credit Agreement executed in February 2017. As permitted by FASB issued ASU 2015-15,

Revenue Recognition	Revenue Recognition — Revenue from the Company’s premium services is recognized on a daily basis over the subscription term as the services are delivered, provided that there is persuasive evidence of an arrangement, the fee is fixed or determinable and collectability is deemed reasonably assured. Subscription periods range from monthly to ten years. The Company’s software cannot be run on another entity’s hardware and customers do not have the right to take possession of the software and use it on their own or another entity’s hardware. Revenue from the Company’s audio services is recognized upon actual usage of audio minutes or the expiration of audio minutes purchased in prepaid plans. Any unbilled audio revenue is accrued for in the period the usage occurs. The Company’s multi-element arrangements typically include subscription and professional services, which may include development services. The Company evaluates each element within the arrangement to determine if they can be accounted for as separate units of accounting. If the delivered item or items have value to the customer on a standalone basis, either because they are sold separately by any vendor or the customer could resell the delivered item or items on a standalone basis, the Company has determined that the deliverables within these arrangements qualify for treatment as separate units of accounting. Accordingly, the Company recognizes revenue for each delivered item or items as a separate earnings process commencing when all of the significant performance obligations have been performed and when all of the revenue recognition criteria have been met. Professional services revenue recognized as a separate earnings process under multi-element arrangements has been immaterial to date. In cases where the Company has determined that the delivered items within its multi-element arrangements do not have value to the customer on a stand-alone basis, the arrangement is accounted for as a single unit of accounting and the related consideration is recognized ratably over the estimated customer life, commencing when all of the significant performance obligations have been delivered and when all of the revenue recognition criteria have been met. Revenue from these multi-element arrangements has been immaterial to date.

When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there is impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. Through September 30, 2017, the Company recorded no material impairments.

As this adoption method does not result in a recast of the prior year financial statements, ASC 606 requires the Company to provide additional disclosures during the year of adoption of the amount by which each financial statement line item is affected by adoption of the new standard and explanation of the reasons for significant changes. The Company is currently evaluating the impact of the adoption of ASC 606 to its consolidated financial statements, accounting policies, IT systems and processes. The Company has allocated internal and external resources to assist in its implementation and evaluation of the impact of ASC 606 and has made enhancements to its financial information systems to assist in financial reporting under ASC 606. While the Company cannot reliably estimate the expected financial statement impact at this time, the Company expects the revenue recognition of its primary revenue streams to remain substantially unchanged and therefore, does not expect a material impact on its revenues upon adoption of ASC 606. The adoption of ASC 606 will have an impact on the Company's consolidated financial statements with respect to its accounting for sales commissions related to customer arrangements. In making this determination the Company has also considered the impact of the guidance in ASC 340-40, Other Assets and Deferred Costs; Contracts with Customers 2014-09 340-40”). 340-40, On February 25, 2016, the FASB issued ASU 2016-02, Leases 2016-02”) , right-of-use 2016-02 right-of-use On January 26, 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment 2017-04”), 2017-04 2017-04 On November 17, 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB’s EITF) 2016-18”). 2016-18 2016-18
