DESCRIPTION OF BUSINESS AND BAS

DESCRIPTION OF BUSINESS AND BASIS FOR PRESENTATION	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS FOR PRESENTATION	1. DESCRIPTION OF BUSINESS AND BASIS FOR PRESENTATION Yelp Inc. was incorporated in Delaware on September 3, 2004. Except where specifically noted or the context otherwise requires, the use of terms such as the “Company” and “Yelp” in these Notes to Condensed Consolidated Financial Statements refers to Yelp Inc. and its subsidiaries. Yelp connects people with great local businesses by bringing “word of mouth” online and providing a platform for businesses and consumers to engage and transact. Yelp’s platform is transforming the way people discover local businesses; every day, millions of consumers visit its website or use its mobile app to find great local businesses to meet their everyday needs. Businesses of all sizes use the Yelp platform to engage with consumers at the critical moment when they are deciding where to spend their money. Basis of Presentation The accompanying interim condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K filed with the SEC on February 24, 2016 (the “Annual Report”). The unaudited condensed consolidated balance sheet as of December 31, 2015 included herein was derived from the audited consolidated financial statements as of that date, but does not include all disclosures required by GAAP, including certain notes to the financial statements. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements, except as follows: Effective as of January 1, 2016, the Company adopted Accounting Standards Update 2016-09, “Compensation—Stock Compensation (Topic 718)” (“ASU 2016-09”). ASU 2016-09 permits entities to make an accounting policy election related to how forfeitures will impact the recognition of compensation cost for stock-based compensation: to estimate the total number of awards for which the requisite service period will not be rendered (as currently required) or to account for forfeitures as they occur. Upon early adoption of ASU 2016-09, the Company elected to change its accounting policy to account for forfeitures as they occur. The change was applied on a modified retrospective basis with a cumulative-effect adjustment to retained earnings of $1.1 million (which reduced the accumulated deficit) as of January 1, 2016. ASU 2016-09 also eliminates the requirement that excess tax benefits be realized as a reduction in current taxes payable before the associated tax benefit can be recognized as an increase in paid in capital. Approximately $164.1 million of federal net operating losses, $125.7 million of state net operating losses, $1.8 million of Ireland net operating losses, $1.3 million of federal research and development tax credits and $0.1 million of state Enterprise Zone credits (none of which were included in the deferred tax assets recognized in the statement of financial position as of December 31, 2015) have been attributed to tax deduction for stock-based compensation in excess of the related book expense. Under ASU 2016-09, these previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2016, the start of the year in which the Company early adopted ASU 2016-09. The U.S. federal and state net operating losses and credits recognized as of January 1, 2016, as described above, have been offset by a valuation allowance. As a result, only the Ireland net operating losses resulted in a cumulative-effect adjustment to retained earnings of $0.2 million (which reduced the accumulated deficit) as of June 30, 2016. Additionally, ASU 2016-09 addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. The Company is now required to present excess tax benefits as an operating activity in the same manner as other cash flows related to income taxes on the statement of cash flows rather than as a financing activity. The Company adopted this change prospectively. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments of a normally recurring nature necessary for the fair presentation of the interim periods presented. Significant Accounting Policies Stock-Based Compensation Prior to January 1, 2016, stock-based compensation expense was recorded net of estimated forfeitures in the Company’s consolidated statements of income (loss) and, accordingly, was recorded for only those stock-based awards that the Company expected to vest. The Company estimated the forfeiture rate based on historical forfeitures of equity awards and adjusted the rate to reflect changes in facts and circumstances, if any. The Company revised its estimated forfeiture rate if actual forfeitures differed from its initial estimates. Effective as of January 1, 2016, the Company adopted a change in accounting policy in accordance with ASU 2016-09 to account for forfeitures as they occur. The change was applied on a modified retrospective basis, and no prior periods were restated as a result of this change in accounting policy. Income Taxes Effective as of January 1, 2016, the Company early adopted a change in accounting policy in accordance with ASU 2016-09 to account for excess tax benefits and tax deficiencies as income tax expense or benefit, treated as discrete items in the reporting period in which they occur, and to recognize previously unrecognized deferred tax assets that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation recognized for financial reporting. The change was applied on a modified retrospective basis; no prior periods were restated as a result of this change in accounting policy. There have been no other material changes to the Company’s significant accounting policies from those described in the Annual Report. Recent Accounting Pronouncements Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09 "Revenue from Contracts with Customers" (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue when they transfer promised goods or services to customers, in an amount that reflects the consideration that the entity expects to be entitled to in exchange for such goods or services. As currently issued and amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, though early adoption is permitted for annual reporting periods beginning after December 15, 2016. In March, April and May 2016, the FASB issued implementation guidance on the considerations in principal versus agent determination, Identifying Performance Obligations and Licensing and Narrow-Scope Improvements and Practical Expedients, respectively. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 and the related implementation guidance on its consolidated financial statements. In January 2016, FASB issued Accounting Standards Update 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)” (“ASU 2016-01”). The new standard provides guidance for the recognition, measurement, presentation and disclosure of financial instruments. This guidance is effective for annual and interim periods beginning after December 15, 2017, and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its consolidated financial statements. In February 2016, FASB issued Accounting Standards Update No. 2016-02, “Leases” (“ASU 2016-02”). The new guidance generally requires an entity to recognize on its balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard requires a modified retrospective transition for existing leases to each prior reporting period presented. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on its consolidated financial statements. Principles of Consolidation These unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of the Company’s unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the unaudited interim condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	2. FAIR VALUE OF FINANCIAL INSTRUMENTS The Company’s investments in money market accounts are recorded as cash equivalents at fair value in the consolidated financial statements. All other financial instruments are classified as held-to-maturity investments and, accordingly, are recorded at amortized cost; however, the Company is required to determine the fair value of these investments on a recurring basis to identify any potential impairment. The accounting guidance for fair value measurements prioritizes the inputs used in measuring fair value in the following hierarchy: Level 1 Level 2 Level 3 This hierarchy requires the Company to use observable market data, when available, to minimize the use of unobservable inputs when determining fair value. The Company’s money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices in active markets. The Company’s commercial paper, corporate bonds, agency bonds and agency discount notes are classified within Level 2 of the fair value hierarchy because they have been valued using inputs other than quoted prices in active markets that are observable directly or indirectly. The following table represents the Company’s financial instruments measured at fair value as of June 30, 2016 and December 31, 2015 (in thousands): June 30, 2016 December 31, 2015 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Cash Equivalents: Money market funds $ 121,033 $ - $ - $ 121,033 $ 86,660 $ - $ - $ 86,660 Agency bonds - - - - - 4,999 - 4,999 Marketable Securities: Commercial paper - 48,887 - 48,887 - 36,981 - 36,981 Corporate bonds - 6,017 - 6,017 - 18,024 - 18,024 Agency bonds - 152,986 - 152,986 - 132,102 - 132,102 Agency discount notes - - - - - 11,986 - 11,986 Total cash equivalents and marketable securities $ 121,033 $ 207,890 $ - $ 328,923 $ 86,660 $ 204,092 $ - $ 290,752

The Company considers such factors as the duration, severity and reason for the decline in value, and the potential recovery period. The Company also considers whether it is more likely than not that it will be required to sell the securities before the recovery of their amortized cost basis, and whether the amortized cost basis cannot be recovered as a result of credit losses. During the three and six months ended June 30, 2016 and 2015, the Company did not recognize any other-than-temporary impairment loss.

Business Combinations [Abstract]
ACQUISITIONS	4. ACQUISITIONS 2015 Acquisition On February 9, 2015, the Company acquired Eat24Hours.com, Inc. (“Eat24”). In connection with the acquisition, all of the outstanding capital stock of Eat24 was converted into the right to receive an aggregate of approximately $75.0 million in cash, less certain transaction expenses, and 1,402,844 shares of Yelp Class A common stock with an aggregate fair value of approximately $59.2 million, as determined on the basis of the closing market price of the Company’s Class A common stock on the acquisition date. Of the total consideration paid in connection with the acquisition, $16.5 million in cash and 308,626 shares were initially held in escrow to secure indemnification obligations. The balance remaining in the escrow fund was $7.8 million in cash and 308,626 shares as of June 30, 2016. The key purpose underlying the acquisition was to obtain an online food ordering solution to drive daily engagement in the Company’s key restaurant vertical. The acquisition was accounted for as a business combination in accordance with Accounting Standards Codification Topic 805, “Business Combinations,” with the results of Eat24’s operations included in the Company’s consolidated financial statements from February 9, 2015. The initial purchase price allocation was as follows (in thousands): February 9, 2015 Fair value of purchase consideration: Cash: Distributed to Eat24 stockholders $ 56,624 Held in escrow account 16,500 Payable on behalf of Eat24 stockholders 1,876 Total cash 75,000 Class A common stock: Distributed to Eat24 stockholders 46,143 Held in escrow account 13,015 Total purchase consideration $ 134,158 Fair value of net assets acquired: Cash and cash equivalents $ 1,578 Intangibles 39,600 Goodwill 110,927 Other assets 6,031 Total assets acquired 158,136 Deferred tax liability (15,207 ) Other liabilities (8,771 ) Total liabilities assumed (23,978 ) Net assets acquired $ 134,158 Estimated useful lives and the amount assigned to each class of intangible assets acquired are as follows: Intangible Asset Type Amount Assigned Useful Life Restaurant relationships 17,400 12.0 years Developed technology 7,400 5.0 years User relationships 12,000 7.0 years Trade name 2,800 4.0 years Weighted average 8.6 years The intangible assets are being amortized on a straight-line basis, which reflects the pattern in which the economic benefits of the intangible assets are being utilized. The goodwill results from the Company’s opportunity to drive daily engagement in its restaurant vertical and potentially expand Eat24’s offering to the approximately one million U.S. restaurants listed on the Company’s platform. None of the goodwill is deductible for tax purposes. The Company recorded no acquisition-related costs for the three and six months ended June 30, 2016 and zero and $0.2 million in acquisition-related costs in the three and six months ended June 30, 2015, respectively, which were included in the general and administrative expense in the accompanying consolidated statements of operations.

GOODWILL AND INTANGIBLE ASSETS The Company’s goodwill is the result of its acquisitions of other businesses, and represents the excess of purchase consideration over the fair value of assets and liabilities acquired. The Company performed its annual goodwill impairment analysis during the three months ended September 30, 2015 and concluded that goodwill was not impaired, as the fair value of each reporting unit exceeded its carrying value. The changes in the carrying amount of goodwill during the six months ended June 30, 2016 were as follows (in thousands): Balance as of December 31, 2015 $ 172,197 Goodwill measurement period adjustment 146 Effect of currency translation 565 Balance as of June 30, 2016 $ 172,908 Intangible assets at June 30, 2016 and December 31, 2015 consisted of the following (dollars in thousands): Weighted Gross Net Average Carrying Accumulated Carrying Remaining Amount Amortization Amount Life June 30, 2016: Restaurant and user relationships $ 29,400 $ (4,399 ) $ 25,001 8.7 years Developed technology 9,302 (3,296 ) 6,006 3.6 years Content 3,842 (2,396 ) 1,446 2.4 years Trade name and other 3,354 (1,515 ) 1,839 2.6 years Domains and data licenses 2,787 (1,087 ) 1,700 3.5 years Advertiser relationships 1,652 (1,652 ) - 0.0 years Total $ 50,337 $ (14,345 ) $ 35,992 Weighted Gross Net Average Carrying Accumulated Carrying Remaining Amount Amortization Amount Life December 31, 2015: Restaurant and user relationships $ 29,400 $ (2,817 ) $ 26,583 9.1 years Developed technology 9,295 (2,441 ) 6,854 4.1 years Content 3,922 (2,066 ) 1,856 2.7 years Trade name and other 3,350 (1,139 ) 2,211 3.1 years Domains and data licenses 2,625 (835 ) 1,790 3.9 years Advertiser relationships 1,708 (1,708 ) - 0.0 years Total $ 50,300 $ (11,006 ) $ 39,294 Amortization expense was $1.7 million and $1.8 million for the three months ended June 30, 2016 and 2015, respectively, and $3.4 million and $3.0 million for the six months ended June 30, 2016 and 2015, respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	11. COMMITMENTS AND CONTINGENCIES Office Facility Leases The Company has subleased certain office facilities under operating lease agreements that expire in 2021. The Company recognizes sublease rentals as a reduction in rental expense on a straight-line basis over the lease period. Sublease rentals were $0.5 million and $0.4 million for the three months ended June 30, 2016 and 2015, respectively, and $1.0 million and $0.4 million for the six months ended June 30, 2016 and 2015, respectively. Legal Proceedings In August 2014, two putative class action lawsuits alleging violations of federal securities laws were filed in the U.S. District Court for the Northern District of California, naming as defendants the Company and certain of its officers. The lawsuits allege violations of the Exchange Act by the Company and certain of its officers for allegedly making materially false and misleading statements regarding the Company’s business and operations between October 29, 2013 and April 3, 2014. These cases were subsequently consolidated and, in January 2015, the plaintiffs filed a consolidated complaint seeking unspecified monetary damages and other relief. Following the court’s dismissal of the consolidated complaint on April 21, 2015, the plaintiffs filed a first amended complaint on May 21, 2015. On November 24, 2015, the court dismissed the first amended complaint with prejudice, and entered judgment in the Company’s favor on December 28, 2015. The plaintiffs have appealed this decision to the U.S. Court of Appeals for the Ninth Circuit. On April 23, 2015, a putative class action lawsuit was filed by former Eat24 employees in the Superior Court of California for San Francisco County, naming as defendants the Company and Eat24. The lawsuit asserts that the defendants failed to permit meal and rest periods for certain current and former employees working as Eat24 customer support specialists, and alleges violations of the California Labor Code, applicable Industrial Welfare Commission Wage Orders and the California Business and Professions Code. The plaintiffs seek monetary damages in an unspecified amount and injunctive relief. On May 29, 2015, plaintiffs filed a first amended complaint asserting an additional cause of action for penalties under the Private Attorneys General Act. In January 2016, the Company reached a preliminary agreement to settle this matter for payments in the aggregate amount of up to approximately $0.6 million, which the court preliminarily approved on June 27, 2016. The settlement is currently awaiting final court approval. On June 24, 2015, a former Eat24 sales employee filed a lawsuit, on behalf of herself and a putative class of current and former Eat24 sales employees, against Eat24 in the Superior Court of California for San Francisco County. The lawsuit alleges that Eat24 failed to pay required wages, including overtime wages, allow meal and rest periods and maintain proper records, and asserts causes of action under the California Labor Code, applicable Industrial Welfare Commission Wage Orders and the California Business and Professions Code. The plaintiff seeks monetary damages and penalties in unspecified amounts, as well as injunctive relief. On August 3, 2015, the plaintiff filed a first amended complaint asserting an additional cause of action for penalties under the Private Attorneys General Act. In January 2016, the Company reached a preliminary agreement to settle this matter for payments in the aggregate amount of up to approximately $0.2 million. Once finalized, the settlement will be subject to court approval. Based on the preliminary settlement agreements reached in connection with the two lawsuits by former Eat24 employees described above, the Company recognized a liability for each of the proposed settlement amounts as part of its accrued liabilities as of June 30, 2016. In February 2016, $1.1 million was released to the Company from the escrow fund established in connection with the acquisition of Eat24, to fund such settlement amounts and related legal expenses. Indemnification Agreements While the outcome of claims cannot be predicted with certainty, the Company does not believe that the outcome of any claims under the indemnification arrangements will have a material effect on the Company’s financial position, results of operations or cash flows.

In July 2011, the Company adopted the 2011 Plan, terminated the 2005 Plan and provided that no further stock awards were to be granted under the 2005 Plan. All outstanding stock awards under the 2005 Plan continue to be governed by their existing terms. Upon the effectiveness of the underwriting agreement in connection with the Company’s initial public offering (“IPO”), the Company terminated the 2011 Plan and all shares that were reserved under the 2011 Plan but not issued were assumed by the 2012 Plan. No further awards will be granted pursuant to the 2011 Plan. All outstanding stock awards under the 2011 Plan continue to be governed by their existing terms. Under the 2012 Plan, the Company has the ability to issue incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock units (“RSUs”), restricted stock awards (“RSAs”), performance units and performance shares. Additionally, the 2012 Plan provides for the grant of performance cash awards to employees, directors and consultants. Stock Options Stock options granted under the 2012 Plan are granted at a price per share not less than the fair value of a share of the Company’s common stock at date of grant. Options granted to date generally vest over a four-year period, on one of three schedules: (a) 25% vesting at the end of one year and the remaining shares vesting monthly thereafter; (b) 10% vesting over the first year, 20% vesting over the second year, 30% vesting over the third year and 40% vesting over the fourth year; or (c) ratably on a monthly basis. Options granted are generally exercisable for up to 10 years. A summary of stock option activity for the six months ended June 30, 2016 is as follows: Options Outstanding Weighted- Average Weighted- Remaining Aggregate Average Contractual Intrinsic Number of Exercise Term (in Value Shares Price years) (in thousands) Outstanding – January 1, 2016 8,206,356 20.93 6.44 $ 92,454 Granted 1,199,768 21.94 Exercised (341,710 ) 9.89 Canceled (111,478 ) 38.66 Outstanding – June 30, 2016 8,952,936 21.27 6.48 $ 106,053 Options vested and exercisable as of June 30, 2016 6,302,577 18.03 5.72 $ 89,290 Aggregate intrinsic value represents the difference between the closing price of the Company’s Class A common stock and the exercise price of outstanding, in-the-money options. The total intrinsic value of options exercised was approximately $3.2 million and $11.0 million for the three months ended June 30, 2016 and 2015, respectively, and $4.8 million and $21.2 million for the six months ended June 30, 2016 and 2015, respectively. The weighted-average grant date fair value of options granted was $9.18 and $20.64 per share for the three months ended June 30, 2016 and 2015, respectively, and $9.42 and $26.65 per share for the six months ended June 30, 2016 and 2015, respectively. As of June 30, 2016, total unrecognized compensation costs related to unvested stock options was approximately $31.2 million, which is expected to be recognized over a weighted-average time period of 1.97 years. RSUs and RSAs The cost of RSUs and RSAs is determined using the fair value of the Company’s common stock on the date of grant. RSUs and RSAs generally vest over a four-year period, on one of three schedules: (a) 25% vesting at the end of one year and the remaining vesting quarterly or annually thereafter; (b) 10% vesting over the first year, 20% vesting over the second year, 30% vesting over the third year and 40% vesting over the fourth year; or (c) ratably on a quarterly basis.

Employee Stock Purchase Plan The ESPP allows eligible employees to purchase shares of the Company’s Class A common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations, during designated offering periods. At the end of each offering period, employees are able to purchase shares at 85% of the fair market value of the Company’s Class A common stock on the last day of the offering period. There were 200,953 shares purchased by employees under the ESPP at a weighted-average purchase price of $22.26 per share during the three and six months ended June 30, 2016. There were 162,373 shares purchased by employees under the ESPP at a weighted-average purchase price of $31.17 per share during the three and six months ended June 30, 2015. The Company recognized $0.5 million and $1.3 million of stock-based compensation expense related to the ESPP in the three months ended June 30, 2016 and 2015, respectively, and $0.7 million and $2.7 million in the six months ended June 30, 2016 and 2015, respectively.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE	13. NET INCOME (LOSS) PER SHARE Basic and diluted net income (loss) per share attributable to common stockholders are presented in conformity with the “two-class method” required for participating securities. Shares of Class A and Class B common stock are the only outstanding equity in the Company. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Shares of Class B common stock may be converted into Class A common stock at any time at the option of the stockholder, and are automatically converted upon sale or transfer to Class A common stock, subject to certain limited exceptions, and in connection with certain other conversion events. Basic net income (loss) per share is computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of shares of common stock and, if dilutive, potential shares of common stock outstanding during the period. The Company’s potential shares of common stock consist of the incremental shares of common stock issuable upon the exercise of stock options, shares issuable upon the vesting of RSUs and, to a lesser extent, unvested shares subject to RSAs and purchases related to the ESPP. The dilutive effect of these potential shares of common stock is reflected in diluted earnings per share by application of the treasury stock method. The computation of the diluted net income (loss) per share of Class A common stock assumes the conversion of Class B common stock, while the diluted net income (loss) per share of Class B common stock does not assume the conversion of Class B common stock. The undistributed earnings are allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B common stock is assumed in the computation of the diluted net income (loss) per share of Class A common stock, the undistributed earnings are equal to net income (loss) for that computation. The following table presents the calculation of basic and diluted net income (loss) per share (in thousands, except per share data): Three Months Ended June 30, 2016 2015 Class A Class B Class A Class B Net income (loss) attributable to common stockholders $ 399 $ 50 $ (1,138 ) $ (167 ) Basic Shares: Weighted-average common shares outstanding 68,018 8,449 65,107 9,524 Net income (loss) per share attributable to common stockholders Basic: $ 0.01 $ 0.01 $ (0.02 ) $ (0.02 ) Three Months Ended June 30, 2016 2015 Class A Class B Class A Class B Diluted net income (loss) per share attributable to common stock holders: Numerator: Allocation of undistributed earnings for basic computation $ 399 $ 50 $ (1,138 ) $ (167 ) Reallocation of undistributed earnings as a result of conversion of Class B to Class A shares 50 - - - Reallocation of undistributed earnings to Class B shares - 7 - - Allocation of undistributed earnings (losses) $ 449 $ 57 $ (1,138 ) $ (167 ) Denominator: Number of shares used in basic calculation 68,018 8,449 65,107 9,524 Weighted-average effect of dilutive securities Conversion of Class B to Class A shares 8,449 - - - Stock options 2,106 1,591 - - Restricted stock units 398 - - - Contingently issuable shares 309 - - - Number of shares used in diluted calculation 79,280 10,040 65,107 9,524 Diluted net income (loss) per share attributable to common stockholders $ 0.01 $ 0.01 $ (0.02 ) $ (0.02 ) Six Months Ended June 30, 2016 2015 Class A Class B Class A Class B Net loss attributable to common stockholders $ (13,303 ) $ (1,700 ) $ (2,252 ) $ (337 ) Basic Shares: Weighted-average common shares outstanding 67,542 8,634 64,363 9,646 Diluted Shares: Weighted-average shares used to compute diluted net loss per share 67,542 8,634 64,363 9,646 Net loss per share attributable to common stockholders Basic: $ (0.20 ) $ (0.20 ) $ (0.03 ) $ (0.03 ) Diluted: $ (0.20 ) $ (0.20 ) $ (0.03 ) $ (0.03 ) The following weighted-average stock-based instruments were excluded from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Stock options 3,385 8,562 8,953 8,562 Restricted stock units and awards 3,582 2,269 6,445 2,269 Contingently issuable shares - 309 309 309 ESPP - 22 - 22

Income Tax Disclosure [Abstract]
INCOME TAXES	14. INCOME TAXES The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are to be reinvested indefinitely. The Company recorded an income tax benefit of $1.3 million and an income tax provision of $1.7 million for the three months ended June 30, 2016 and 2015, respectively, and an income tax provision of $0.2 million and an income tax benefit of $0.7 million for the six months ended June 30, 2016 and 2015, respectively. The tax provision for the six months ended June 30, 2016 is due to $0.1 million in U.S. federal and state and foreign income tax expense and $0.1 million of discrete expense. The tax benefit for the six months ended June 30, 2015 is due to $0.7 million in discrete benefits. Accounting for income taxes for interim periods generally requires the provision for income taxes to be determined by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pretax income or loss excluding unusual or infrequently occurring discrete items) for the reporting period. For the three and six months ended June 30, 2016 a discrete effective tax rate method was used in jurisdictions where a small change in estimated ordinary income has a significant impact on the annual effective tax rate. The primary difference between the effective tax rate and the federal statutory tax rate relates to the valuation allowances on certain of the Company’s net operating losses, foreign tax rate differences, meals and entertainment, tax credits, and non-deductible stock-based compensation expense. Jurisdictions where no benefit is recorded on forecasted losses were excluded from the consolidated effective tax rate. As of June 30, 2016, the total amount of gross unrecognized tax benefits was $5.8 million, $5.0 million of which is subject to a full valuation allowance and would not affect the Company’s effective tax rate if recognized. As of June 30, 2016, the Company had an immaterial amount related to the accrual of interest and penalties. During the three and six months ended June 30, 2016, the Company’s gross unrecognized tax benefits increased by $0.2 million and $0.8 million, respectively, an immaterial amount of which would affect the Company’s effective tax rate if recognized. In addition, the Company is subject to the continuous examination of its income tax returns by the IRS and other tax authorities. The Company’s federal and state income tax returns for fiscal years 2004 through 2015 remain open to examination. In the Company’s most significant foreign jurisdictions — Ireland, the United Kingdom and Germany — the open tax years range from 2010 to 2015. The Company regularly assesses the likelihood of adverse outcomes resulting from examinations to determine the adequacy of its provision for income taxes, and monitors the progress of ongoing discussions with tax authorities and the impact, if any, of the expected expiration of the statute of limitations in various taxing jurisdictions. The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Although the timing of the resolution or closure of audits is not certain, the Company believes it is reasonably possible that its unrecognized tax benefits could be reduced by up to $0.2 million over the 12 months following December 31, 2015.

Segment Reporting [Abstract]
INFORMATION ABOUT REVENUE AND GEOGRAPHIC AREAS	15. INFORMATION ABOUT REVENUE AND GEOGRAPHIC AREAS The Company considers operating segments to be components of the Company in which separate financial information is available that is evaluated regularly by the Company’s chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker for the Company is the Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by product line and geographic region for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results or plans for levels or components below the consolidated unit level. Accordingly, the Company has determined that it has a single operating and reporting segment. Net Revenue The table below presents the Company’s net revenue by product line for the periods presented (in thousands). Revenue by geography is based on the billing address of the customer.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements, except as follows: Effective as of January 1, 2016, the Company adopted Accounting Standards Update 2016-09, “Compensation—Stock Compensation (Topic 718)” (“ASU 2016-09”). ASU 2016-09 permits entities to make an accounting policy election related to how forfeitures will impact the recognition of compensation cost for stock-based compensation: to estimate the total number of awards for which the requisite service period will not be rendered (as currently required) or to account for forfeitures as they occur. Upon early adoption of ASU 2016-09, the Company elected to change its accounting policy to account for forfeitures as they occur. The change was applied on a modified retrospective basis with a cumulative-effect adjustment to retained earnings of $1.1 million (which reduced the accumulated deficit) as of January 1, 2016. ASU 2016-09 also eliminates the requirement that excess tax benefits be realized as a reduction in current taxes payable before the associated tax benefit can be recognized as an increase in paid in capital. Approximately $164.1 million of federal net operating losses, $125.7 million of state net operating losses, $1.8 million of Ireland net operating losses, $1.3 million of federal research and development tax credits and $0.1 million of state Enterprise Zone credits (none of which were included in the deferred tax assets recognized in the statement of financial position as of December 31, 2015) have been attributed to tax deduction for stock-based compensation in excess of the related book expense. Under ASU 2016-09, these previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2016, the start of the year in which the Company early adopted ASU 2016-09. The U.S. federal and state net operating losses and credits recognized as of January 1, 2016, as described above, have been offset by a valuation allowance. As a result, only the Ireland net operating losses resulted in a cumulative-effect adjustment to retained earnings of $0.2 million (which reduced the accumulated deficit) as of June 30, 2016. Additionally, ASU 2016-09 addresses the presentation of excess tax benefits and employee taxes paid on the statement of cash flows. The Company is now required to present excess tax benefits as an operating activity in the same manner as other cash flows related to income taxes on the statement of cash flows rather than as a financing activity. The Company adopted this change prospectively. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments of a normally recurring nature necessary for the fair presentation of the interim periods presented.
Stock-Based Compensation	Stock-Based Compensation Prior to January 1, 2016, stock-based compensation expense was recorded net of estimated forfeitures in the Company’s consolidated statements of income (loss) and, accordingly, was recorded for only those stock-based awards that the Company expected to vest. The Company estimated the forfeiture rate based on historical forfeitures of equity awards and adjusted the rate to reflect changes in facts and circumstances, if any. The Company revised its estimated forfeiture rate if actual forfeitures differed from its initial estimates. Effective as of January 1, 2016, the Company adopted a change in accounting policy in accordance with ASU 2016-09 to account for forfeitures as they occur. The change was applied on a modified retrospective basis, and no prior periods were restated as a result of this change in accounting policy.
Income Taxes	Income Taxes Effective as of January 1, 2016, the Company early adopted a change in accounting policy in accordance with ASU 2016-09 to account for excess tax benefits and tax deficiencies as income tax expense or benefit, treated as discrete items in the reporting period in which they occur, and to recognize previously unrecognized deferred tax assets that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation in excess of compensation recognized for financial reporting. The change was applied on a modified retrospective basis; no prior periods were restated as a result of this change in accounting policy. There have been no other material changes to the Company’s significant accounting policies from those described in the Annual Report.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09 "Revenue from Contracts with Customers" (“ASU 2014-09”). ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue when they transfer promised goods or services to customers, in an amount that reflects the consideration that the entity expects to be entitled to in exchange for such goods or services. As currently issued and amended, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, though early adoption is permitted for annual reporting periods beginning after December 15, 2016. In March, April and May 2016, the FASB issued implementation guidance on the considerations in principal versus agent determination, Identifying Performance Obligations and Licensing and Narrow-Scope Improvements and Practical Expedients, respectively. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 and the related implementation guidance on its consolidated financial statements. In January 2016, FASB issued Accounting Standards Update 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10)” (“ASU 2016-01”). The new standard provides guidance for the recognition, measurement, presentation and disclosure of financial instruments. This guidance is effective for annual and interim periods beginning after December 15, 2017, and early adoption is not permitted. The Company is currently evaluating the impact of the adoption of ASU 2016-01 on its consolidated financial statements. In February 2016, FASB issued Accounting Standards Update No. 2016-02, “Leases” (“ASU 2016-02”). The new guidance generally requires an entity to recognize on its balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard requires a modified retrospective transition for existing leases to each prior reporting period presented. The Company is currently evaluating the impact of the adoption of ASU 2016-02 on its consolidated financial statements.
Principles of Consolidation	Principles of Consolidation These unaudited interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the Company’s unaudited interim condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the unaudited interim condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.
