Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These 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 for the year ended December 31, 2018, filed with the SEC on March 1, 2019. The condensed consolidated balance sheet as of December 31, 2018 has been derived from the audited consolidated financial statements as of that date but does not include all of the information and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The interim financial information is unaudited, but reflects all normal recurring adjustments that are, in the opinion of management, necessary to fairly present the information set forth herein. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the operating results to be expected for the full year or any future periods. There have been no material changes in the Company’s significant accounting policies other than the adoption of Accounting Standards Update (“ASU”) ASU 2016-02 , Leases (Topic 842), Use of Judgements and Estimates The preparation of the Company’s condensed consolidated financial statements in accordance with U.S. GAAP requires management to make certain estimates, judgements, and assumptions that affect the reported amounts of assets and liabilities and related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Significant items subject to such estimates and assumptions include: for revenue recognition, determining the nature and timing of satisfaction of performance obligations, variable consideration, determining the stand-alone selling prices of performance obligations, gross versus net revenue reporting, evaluation of customer versus vendor relationships, and other obligations such as sales return reserves and customer incentive programs; the valuation of inventory, the valuation of deferred income tax assets, the recognition and disclosure of contingent liabilities and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Actual results may differ from the Company’s estimates and assumptions. Principles of Consolidation The condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Comprehensive Income (Loss) Comprehensive income (loss) includes unrealized gains (loss) on the Company’s short-term investments for the three months ended March 31, 2019. The Company did not have any short-term investments during the three months ended March 31, 2018. As a result, comprehensive income (loss) was equal to the net loss for the three months ended March 31, 2018. Concentrations Customers accounting for 10% or more of the Company’s net revenue were as follows: Three Months Ended March 31, 2019 March 31, 2018 Customer B 11 % 10 % Customer C 12 % 17 % Customer G * 11 % Customers accounting for 10% or more of the Company’s accounts receivable were as follows: As of March 31, 2019 December 31, 2018 Customer D 15 % 11 % * Less than 10% Restricted Cash Restricted cash is comprised of cash collateral for outstanding letters of credit related to operating leases of office facilities. As of March 31, 2019, the Company had restricted cash of $26.4 million. The Company did not have any restricted cash as of December 31, 2018. Content Licensing Fees The Company acquires rights to video content for viewing on The Roku Channel. Consideration for these content rights can include a fixed fees and/or a share of advertising revenue. The Company capitalizes the content fees and records a corresponding liability at the gross amount of the liability when the license period has begun, the cost of the content is determinable, and the content is accepted and available for streaming. The Company amortizes licensed content assets into “Cost of Revenue, Platform” over the contractual window of availability . As of March 31, 2019, . Recently In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-02, Leases (Topic 842), On January 1, 2019, the Company adopted the guidance in ASC 842 using the optional transition method and recorded right-of-use (“ROU”) assets and lease liabilities on its condensed consolidated balance sheet. As a result, periods prior to 2019 were not adjusted. On the adoption date, the Company recognized ROU assets totaling $39.9 million, lease liabilities totaling $42.1 million and reclassification of deferred and prepaid rents of $2.2 million to ROU assets on its condensed consolidated balance sheet. There was Recently Issued Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Topic 350), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	3. REVENUE Revenue Recognition The Company enters into contracts that may include various combinations of products and services, which are generally capable of being distinct and are accounted for as separate performance obligations. Revenue is recognized when control of promised products or services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those products or services. Shipping charges billed to customers are included in revenue and the related shipping costs are included in cost of revenue. Revenue is recorded net of taxes collected or accrued. Sales taxes are recorded as current liabilities until remitted to the relevant government authority. The Company does not have any capitalized costs associated with contract acquisition because most direct contract acquisition costs relate to contracts that are recognized over a period of one year or less. Arrangements with Multiple Performance Obligations The Company’s contracts may contain multiple distinct performance obligations. The computed transaction price of each contract is allocated to each performance obligation based on a relative stand-alone selling price (“SSP”). For performance obligations routinely sold separately, the SSP is determined by evaluating such stand-alone sales. For those performance obligations that are not routinely sold separately, the Company determines SSP based on a market assessment approach, or on an expected cost-plus margin approach. Nature of Products and Services Platform Segment: The Company’s platform segment generates revenue from advertising sales, subscription and transaction revenue shares, the sale of branded channel buttons on remote controls and licensing arrangements with TV brands and service operators. Player Segment: The Company sells the majority of its players through retail distribution channels, including brick and mortar and online retailers, and through the Company’s website. The Company’s player revenue includes allowances for returns and sales incentives in the estimated transaction price. These estimates are based on historical experience and anticipated performance. Revenue Disaggregation The Company’s disaggregated revenue is represented by the two reportable segments discussed in Note 14. The disaggregation is based on the evaluations that are regularly performed by the chief operating decision maker (“CODM”) for purposes of allocating resources and evaluating financial performance. The Company’s CODM is its Chief Executive Officer. Revenue Allocated to Future Performance Obligations Revenue allocated to remaining performance obligations represents estimated contracted revenue that has not yet been recognized which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Estimated contracted revenue was $100.3 million 84 Contract Balances Contract balances include accounts receivable, contract assets and contract liabilities. Accounts receivable are recorded at the amount invoiced, net of an allowance for doubtful accounts and sales incentives. The payment terms with customers vary by contract. Contract assets are created when the timing of invoicing to a customer occurs subsequent to revenue recognition. Contract assets are transferred to accounts receivable when the right to bill becomes unconditional. The Company’s contract assets are current in nature and are included in “Prepaid expenses and other current assets ”. The Company did not have any impairments relating to contract assets. Contract liabilities are recorded as deferred revenue and primarily relate to timing differences between the billing terms and the fulfillment of performance obligations. Revenue is recognized when the performance obligation is completed and delivered or transfer of control occurs. The table below reflects the contract balances of the Company (in thousands): As of As of March 31, 2019 December 31, 2018 Accounts receivable, net $ 174,195 $ 183,078 Contract assets, current 2,351 753 Deferred revenue, current 41,939 45,442 Deferred revenue, non-current 15,297 19,594 Total deferred revenue $ 57,236 $ 65,036 Contract assets increased by approximately $1.6 million during the three months ended March 31, 2019 primarily due to a $1.8 million increase in contract asset from one customer where the Company’s right to bill falls into subsequent period. Deferred revenue decreased by approximately $7.8 million during the three months ended March 31, 2019 primarily due to revenue recognized of $5.0 million pursuant to customer acceptance of a milestone.

Financial assets and liabilities measured using Level 1 inputs include cash equivalents, restricted cash, accounts receivable, prepaid expenses, accounts payable and accrued liabilities. The Company considers all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. The Company measured money market funds of $23.4 and $8.3 million as cash equivalents as of March 31, 2019 and December 31, 2018, respectively, using Level 1 inputs. Level 2 —Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. The Company measured its short-term investments using Level 2 inputs. Level 3 —Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company did not use Level 3 inputs to measure any assets or liabilities as of March 31, 2019 and December 31, 2018.

Leases [Abstract]
Leases	7. LEASES The Company determines if an arrangement contains a lease at its inception. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term and leases are included in operating lease ROU assets, accrued liabilities, for the current portion of operating lease liabilities, and operating lease liabilities, non-current on our consolidated balance sheets. As the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future lease payments. The Company took into consideration its credit rating and the length of the lease when calculating the incremental borrowing rate. The Company considers the options to extend or terminate the lease in determining the lease term, when it is reasonably certain to exercise one of the options. The Company combines lease and non-lease components into a single lease component for its real estate and equipment leases. The Company has entered into operating leases primarily for office real estate. The leases have remaining lease terms ranging from one year to 12 years. Some leases include an option to extend the leases for up to seven years and some leases include an option to terminate after three and a half years. The depreciable life of ROU assets is limited by the expected lease term. The Company earns sublease income from subleases for a portion of the former headquarters. The subleases expire in 2020. The components of lease expense are as follows (in thousands): Three Months Ended March 31, 2019 Operating lease cost $ 4,332 Sublease income (580 ) Net operating lease cost $ 3,752 Supplemental cash flow information related to leases is as follows (in thousands): Three Months Ended March 31, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,866 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 34,534 Supplemental balance sheet information related to leases was as follows (in thousands, except lease term and discount rate As of March 31, 2019 Operating lease right-of-use assets $ 71,013 Included in accounts payable and accrued liabilities: Operating lease liability, current 14,208 Operating lease liability, non-current 59,950 Total operating lease liability $ 74,158 Weighted Average Remaining Lease Term Operating leases (in years) 8.33 Weighted Average Discount Rate Operating leases 5.95 % Future lease payments under operating leases as of March 31, 2019 were as follows (in thousands): Year ending December 31, Operating Leases 2019 (remaining 9 months) $ 13,098 2020 18,288 2021 9,774 2022 9,973 2023 10,064 Thereafter 43,882 Total future lease payments 105,079 Less: imputed interest (22,752 ) Less: expected tenant improvement allowance (8,169 ) Total $ 74,158 As of March 31, 2019, the Company has additional operating leases, primarily corporate offices, that have not yet commenced of $142.6 million.

Debt Disclosure [Abstract]
Debt	8. DEBT The Company did not have any outstanding debt as of March 31, 2019 or December 31, 2018. Senior Secured Term Loan A and Revolving Credit Facilities On February 19, 2019 (the “Closing Date”), the Company entered into a Credit Agreement (the “Credit Agreement”) with Morgan Stanley Senior Funding, Inc. The Credit Agreement provides for (i) a four-year revolving credit facility in the aggregate principal amount of up to $75.0 million (the “Revolving Credit Facility”), (ii) a four-year delayed draw term loan A facility in the aggregate principal amount of up to $75.0 million (the “Term Loan A Facility”) and (iii) an uncommitted incremental facility, subject to the satisfaction of certain financial and other conditions, in the amount of up to (v) $50.0 million, plus (w) 1.0x of the Company’s EBITDA for the most recently completed four fiscal quarter period, plus (x) an additional amount at our discretion, so long as, on a pro forma basis at the time of incurrence, our secured leverage ratio does not exceed 1.50 to 1.00, plus (y) voluntary prepayments of the Revolving Credit Facility and Term Loan A Facility to the extent accompanied by concurrent reductions to the applicable Credit Facility, plus (z) for up to 90 days after the Closing Date, $75.0 million (together with the Revolving Credit Facility and the Term Loan A Facility, collectively, the “Credit Facility”). Borrowings under the Term Loan A Facility may be made by the Company up to 9 months immediately following the Closing Date. On the Closing Date, the Company terminated its Restated 2014 LSA (as defined below) with Silicon Valley Bank. Loans under the Credit Facility bear interest at a rate equal to, at the Company’s election, (i) an alternate base rate, based upon the highest of (x) the prime rate, (y) the federal funds effective date plus ½ of 1% and (z) the one-month LIBOR plus 1%, in each case plus an applicable margin of up to 1% per annum, with step-downs based on its secured leverage ratio or (2) an adjusted one-, two-, three-, or six month LIBOR, at its election, plus an applicable margin of up to 2% per annum, with step-downs based on its secured leverage ratio. Loans under the Term Loan A Facility will amortize in equal quarterly installments beginning on the last day of the fiscal quarter ending after the date of the initial borrowing under the Term Loan A Facility, in an aggregate annual amount equal to (i) on or prior to December 31, 2021, 1.25% of the drawn principal amount of the Term Loan Facility and (ii) thereafter, 2.50% of the drawn principal amount of the Term Loan Facility, with any remaining balance payable on the maturity date of the Term Loan A Facility. The Company’s obligations under the Credit Agreement are secured by substantially all of its assets. In the future, certain of its direct and indirect subsidiaries may be required to guarantee the Credit Agreement. The Company may prepay, and in circumstances is required to prepay, loans under the Credit Agreement without payment of a premium. The Credit Agreement contains customary representations and warranties, customary affirmative and negative covenants, a financial covenant that is tested quarterly and requires the Company to maintain a certain adjusted quick ratio of 1.00 to 1.00, and customary events of default. As of March 31, 2019, the Company is in compliance with all the covenants of the Credit Agreement. The Company incurred debt issuance costs for the Credit Agreement, which are amortized over the contractual term of the agreement. Debt issuance costs are recorded in prepaid expenses and other current assets on the condensed consolidated balance sheet. On May 3, 2019, the Company entered into the Incremental Assumption and Amendment No. 1 to increase the level of commitments for each of the Revolving Credit Facility and Term Loan A Facility from $75.0 million to $100.0 million under the same terms as the Credit Agreement. Refer to Note 15, Subsequent Events, for details. Line of Credit The Company first entered into a loan and security agreement (the “LSA”) with Silicon Valley Bank in July 2011. The LSA was amended and restated in subsequent periods. The amended and restated loan and security agreement (the “Restated 2014 LSA”) entered into in November 2014 provided advances under a revolving line of credit up to $30.0 million and provides for letters of credit to be issued up to $5.0 million. In June 2017, the Company entered into a second amendment to the Restated 2014 LSA (such amendment, the “Second Amendment”). Advances under the Second Amendment carry a floating per annum interest rate equal to, at the Company’s option, (1) the prime rate or (2) LIBOR plus 2.75%, or the prime rate plus 1% depending on certain ratios. The Second Amendment further changed the financial covenant to maintain a current ratio (calculated as current assets, divided by current liabilities less deferred revenue) greater than or equal to 1.25. As of December 31, 2018, the Company was in compliance with all of the covenants in the amended Restated 2014 LSA. On July 18, 2018, the Company entered into a third amendment to the Restated 2014 LSA (such amendment, the “Third Amendment”). The Third Amendment increased the amount by which the Company could utilize its line of credit to support the issuances of letters of credits from $5.0 million to $30.0 million. On February 19, 2019, the Company terminated the Restated 2014 LSA agreement.

Stockholders' Equity	9. STOCKHOLDERS’ EQUITY At-the-Market Offerings On March 12, 2019, the Company entered into an Equity Distribution Agreement with Citigroup Global Markets Inc., as its sales agent, pursuant to which the Company could issue and sell from time-to-time up to $100.0 million maximum aggregate offering price of the Company’s Class A common stock. In March 2019, the Company received gross proceeds of $100.0 million from sales of approximately 1.4 million shares at an average selling price of $72.00 per share and incurred issuance costs of $2.0 million. As of March 31, 2019, the Company had sold all available shares of Class A common stock under this agreement. Preferred Stock The Company is authorized to issue 10 million shares of undesignated preferred stock with rights and preferences determined by the Company’s Board of Directors at the time of issuance. As of March 31, 2019 and December 31, 2018, there were no shares of preferred stock issued and outstanding. Common Stock The Company has two classes of authorized common stock, Class A common stock and Class B common stock. All shares of common stock outstanding immediately prior to the initial public offering (“IPO”), including shares of common stock issued upon the conversion of the convertible preferred stock, were converted into an equivalent number of shares of Class B common stock. All common stock, stock options and restricted stock units issued at the time of and subsequent to the IPO are exercised or vested into shares of Class A common stock. The Company has reserved the following shares of common stock for future issuances (in thousands): As of March 31, 2019 Common stock awards granted under equity incentive plans 18,459 Common stock awards available for issuance under Employee Stock Purchase Plan 2,089 Common stock awards available for issuance under the 2017 Equity Incentive Plan 18,195 Total reserved shares of common stock 38,743 Equity Incentive Plans The 2008 Equity Incentive Plan (the “2008 Plan”) became effective in February 2008. The 2008 Plan allowed for the grant of incentive stock options to employees and for the grant of non-statutory stock options and restricted stock awards to employees, directors and consultants. Subject to certain limitations, options granted under the 2008 Plan were granted at a price per share equivalent to the fair market value on the date of grant and generally vest over four years and have a term of 10 years. Following the Company’s IPO, no further equity awards could be made pursuant to the 2008 Plan. Outstanding stock options at the time of the Company’s IPO are exercisable for Class B common stock under the 2008 Plan. The 2017 Equity Incentive Plan (the “2017 Plan”) became effective in September 2017. The 2017 Plan provides for the grant of incentive stock options to employees and for the grant of non-statutory stock options and restricted stock awards, as well as, other forms of equity compensation to employees, directors and consultants. Stock options and restricted stock units under the 2017 Plan are generally expensed over four years and have a term of 10 years. Only shares of Class A common stock are issued pursuant to equity awards granted under the 2017 Plan. Stock-Based Compensation The Company measures the cost of awards granted under equity incentive plans based on the grant date fair value. The Company uses the straight-line method for expense recognition and recognizes forfeitures as they occur. The following table shows total stock-based compensation expense three months ended March 31, 2019 and 2018 (in thousands): Three Months Ended March 31, 2019 March 31, 2018 Cost of platform revenue $ 59 $ 19 Cost of player revenue 243 44 Research and development 8,532 2,296 Sales and marketing 5,166 1,110 General and administrative 3,864 960 Total stock-based compensation $ 17,864 $ 4,429 Stock Options The summary of the Company’s stock option activity is as follows (in thousands, except price per share data): Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) Weighted Average Grant Date Fair Value Per Share Aggregate Intrinsic Value Balance, December 31, 2018 - outstanding 16,371 $ 8.59 — Granted 4 54.65 — $ 22.96 Exercised (1,974 ) 5.28 — — Forfeited and expired (81 ) 12.52 — — Balance, March 31, 2019 - outstanding 14,320 $ 9.03 6.5 — $ 794,461 Options exercisable at March 31, 2019 7,749 $ 4.93 5.4 — $ 461,744 The intrinsic value for options exercised during the three months ended March 31, 2019 and 2018, was $109.7 million and $56.2 million, respectively. Intrinsic value represents the difference between the fair values of the Company’s common stock and the exercise prices on the date of grant. As of March 31, 2019, the Company had $33.8 million of unrecognized stock compensation expense related to unvested stock options that is expected to be recognized over a weighted-average period of approximately 1.98 years. The fair value of options granted under the equity incentive plans is estimated on the grant date using the Black-Scholes option-valuation model. The assumptions used in the Black-Scholes model are as follows: Three Months Ended March 31, 2019 March 31, 2018 Dividend rate — — Expected term (in years) 5.0 6.1 Risk-free interest rate 2.51 - 2.56% 2.32 - 2.67% Expected volatility 36 % 39 - 40% Restricted Stock Units Pursuant to the 2017 Plan, the Company issues restricted stock units to employees. The fair value of restricted stock units is based on the Company’s closing stock price on the date of grant. The summary of the Company’s restricted stock unit activity is as follows (in thousands, except price per share data): Number of Shares Weighted Average Grant Date Fair Value Per Share Balance, December 31, 2018 - outstanding 3,686 $ 48.50 Awarded 712 50.35 Released (165 ) 45.83 Forfeited (94 ) 56.11 Balance, March 31, 2019 - outstanding 4,139 $ 48.75 The unrecognized compensation cost related to restricted stock units as of March 31, 2019 was $184.5 million, which the Company expects to recognize over 3.19 years. The intrinsic value of restricted stock units that vested during the three months ended March 31, 2019 totaled $11.4 million, which represented the fair value of the Company’s common stock underlying the restricted stock units on their vesting date.

The Company records a liability for noncancelable purchase commitments in excess of its future demand forecasts. The amounts recorded by the Company Content Licensing The Company licenses certain content for users to access through The Roku Channel. The Company records an obligation for licensing of content when it enters into an agreement to obtain future titles and the cost of the content is known. Certain agreements include the obligation to license rights for unknown future titles, the ultimate quantity and/or fees for which are not yet determinable as of the reporting date. As of March 31, 2019, the amounts recorded in “Accrued liabilities” for license purchase commitments were not material. Letters of Credit As of March 31, 2019 and December 31, 2018, the Company had irrevocable letters of credit outstanding in the amount of $26.4 million, related to facilities leases. The letters of credit have various expiration dates through 2030. Contingencies The Company accrues for loss contingencies, including liabilities for intellectual property licensing, when it believes such losses are probable and reasonably estimable. The Company is currently involved in, and may in the future be involved in, legal proceedings, claims, and investigations in the ordinary course of business, including claims for infringing patents, copyrights or other intellectual property rights related to its platform and products, or the content distributed through its platform by the Company or third-party channel developers. Although the results of these proceedings, claims, and investigations cannot be predicted with certainty, the Company does not believe that the final outcome of any matters that it is currently involved in are reasonably likely to have a material adverse effect on its business, financial condition, or results of operations. Indemnification Many of the Company’s agreements include provisions for indemnifying content publishers, licensees, distributors, retailers, contract manufacturers and suppliers in the event that the Company’s products or services or the Company’s technologies incorporated therein, infringe on a third party’s intellectual property rights. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each agreement. To date, the Company has not incurred any material costs as a result of such obligations and has not accrued any liabilities related to such obligations in the consolidated financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	11. INCOME TAXES Income tax benefit for the three months ended March 31, 2019, was $0.14 million, compared to an expense of $0.13 million, for the three months ended March 31, 2018. The income tax benefit for the three months ended March 31, 2019, was primarily attributable to non-U.S. tax benefit associated with the Company's non-U.S. operation. The income tax expense for the three months ended March 31, 2018, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three months ended March 31, 2019, the Company believes it is more likely than not that the tax benefit of the U.S. losses incurred may not be realized. Accordingly, the Company recorded a full valuation allowance against the tax benefits of the U.S. losses incurred. The primary difference between the effective tax rate and the statutory tax rate relates to the valuation allowance on the Company’s U.S. losses. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax assets will not be realized through future operations. As a result of the Company’s analysis of all available objective evidence, both positive and negative, as of March 31, 2019, management believes it is more likely than not that the deferred tax assets will not be fully realizable. Accordingly, the Company has provided a full valuation allowance against its deferred tax assets with the exception of deferred tax assets related to foreign entities in the U.K., China, and Denmark.

Net Loss Per Share	13. NET LOSS PER SHARE The Company’s basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period. For purposes of the calculation of diluted net loss per share options to purchase common stock, restricted stock units and unvested shares of common stock issued upon the early exercise of stock options are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share as their effect is antidilutive. Because the Company has reported a net loss for all periods presented, diluted net loss per common share is the same as the basic net loss per share for all periods presented. The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data): Three Months Ended March 31, 2019 March 31, 2018 Numerator: Net loss allocable to common stockholders $ (9,732 ) $ (6,634 ) Denominator: Weighted-average shares used in computing net loss per share, basic and diluted 110,877 99,488 Net loss per share, basic and diluted $ (0.09 ) $ (0.07 ) The potential common shares that would be excluded from the calculation of diluted net loss per share because of their anti-dilutive effect are as follows (in thousands): Three Months Ended March 31, 2019 March 31, 2018 Equity awards to purchase common stock 18,459 24,933 Unvested shares of common stock issued upon early exercise of stock options and business acquisition 57 126 Total 18,516 25,059

Fair Value	The Company’s financial assets measured at fair value are as follows (in thousands): March 31, 2019 December 31, 2018 Fair Value Level 1 Level 2 Fair Value Level 1 Level 2 Assets: Cash and cash equivalents: Cash $ 213,069 $ 213,069 $ — $ 147,221 $ 147,221 $ — Money market funds 23,431 23,431 — 8,343 8,343 — Restricted cash 26,350 26,350 — — — — Short-term investments: Corporate bonds and commercial paper 22,437 — 22,437 37,151 — 37,151 U.S. government securities 4,964 — 4,964 4,995 — 4,995 Total assets measured and recorded at fair value $ 290,251 $ 262,850 $ 27,401 $ 197,710 $ 155,564 $ 42,146 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal market (or most advantageous market, in the absence of a principal market) for the asset or liability in an orderly transaction between market participants at the measurement date. Further, the Company maximizes the use of observable inputs and minimizes the use of unobservable inputs in measuring fair value, and to utilize a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The three levels of inputs used to measure fair value are as follows: Level 1 —Quoted prices in active markets for identical assets or liabilities. Financial assets and liabilities measured using Level 1 inputs include cash equivalents, restricted cash, accounts receivable, prepaid expenses, accounts payable and accrued liabilities. The Company considers all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. The Company measured money market funds of $23.4 and $8.3 million as cash equivalents as of March 31, 2019 and December 31, 2018, respectively, using Level 1 inputs. Level 2 —Observable inputs other than quoted prices included within Level 1, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs other than quoted prices that are observable or are derived principally from, or corroborated by, observable market data by correlation or other means. The Company measured its short-term investments using Level 2 inputs. Level 3 —Unobservable inputs that are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The Company did not use Level 3 inputs to measure any assets or liabilities as of March 31, 2019 and December 31, 2018.
