Organization Consolidation And Presentation Of Financial Statements [Abstract]
Overview and Summary of Significant Accounting Policies	1. Overview and Summary of Significant Accounting Policies Organization and Description of Business Zynga Inc. (“Zynga,” “we” or the “Company”) is a leading provider of social game services. We develop, market and operate social games as live services played on mobile platforms, such as iOS and Android, and social networking sites such as Facebook. Generally, all of our games are free to play, and we generate substantially all of our revenue through the sale of in-game virtual items and advertising services. Our operations are headquartered in San Francisco, California, and we have several operating locations in the U.S. as well as various international office locations in North America, Asia and Europe. We completed our initial public offering in December 2011 and our Class A common stock is listed on the NASDAQ Global Select Market under the symbol “ZNGA.” Basis of Presentation and Consolidation The accompanying interim consolidated financial statements are presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The interim consolidated financial statements include the operations of the Company and its owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation. The accompanying interim consolidated financial statements and these related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018. Unaudited Interim Financial Information The accompanying interim consolidated balance sheets as of September 30, 2019 and December 31, 2018, the interim consolidated statements of operations, statements of comprehensive income (loss) and statements of stockholders’ equity for the three and nine months ended September 30, 2019 and 2018, the statements of cash flows for the nine months ended September 30, 2019 and 2018 and the notes to interim consolidated financial statements are unaudited. These unaudited interim consolidated financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited interim consolidated financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s statement of financial position and operating results for the periods presented. The results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results expected for the full fiscal year or any other future period. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the interim consolidated financial statements and notes thereto. Significant estimates and assumptions reflected in the financial statements include, but are not limited to, the estimated average playing period of payers that we use for revenue recognition, useful lives of property and equipment and intangible assets, accrued liabilities, income taxes, the fair value of assets and liabilities acquired through business combinations, contingent consideration obligations, the discount rate used in discounting our operating lease liabilities, the interest rate used in calculating the present value of the initial liability component of our convertible notes, stock-based compensation expense and evaluation of recoverability of goodwill, intangible assets, and long-lived assets. Actual results could differ materially from those estimates. For the three and nine months ended September 30, 2019, there was no significant impact from discontinued games or from changes in our estimated average playing period of payers that required adjusting the recognition period of deferred revenue generated in prior periods. For the nine months ended September 30, 2018, we recognized $0.9 million of online game revenue and income from operations from games that have been discontinued as there is no further performance obligation. This change in estimate did not impact our reported earnings per share in the nine months ended September 30, 2018. For the three months ended September 30, 2018, there were no discontinued games that required adjusting the recognition period of deferred revenue generated in prior periods. Further, there were no changes in our estimated average playing period of payers that required adjusting the recognition period of deferred revenue generated in prior periods for the three and nine months ended September 30, 2018. Recent Accounting Pronouncements Issued But Not Yet Adopted In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” ASC Topic 350-40, Internal-Use Software Issued And Adopted In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” “Leases (Topic 842) – Targeted Improvements” Adoption Impact – Lessee Accounting The adoption of ASC Topic 842 on January 1, 2019 resulted in the recognition of right-of-use assets of $9.1 million, which includes the elimination of our remaining prepaid rent and deferred rent balances, current operating lease liabilities of $7.6 million and non-current operating lease liabilities of $12.4 million. The adoption of ASC Topic 842 did not impact our consolidated statement of operations or consolidated statement of cash flows. ASC Topic 842 also amends the provisions of ASC Topic 420 – Exit or Disposal Obligations ASC 360 – Property, Plant, and Equipment As part of the adoption, the new standard allows a number of practical expedients and exemptions. At transition, we elected the following: • The package of practical expedients, which allows us to carryforward our historical lease classification, assessment of whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard; • The practical expedient to not separate non-lease components from the related lease components; and • The exemption to not apply the balance sheet recognition requirements for leases with a lease term of 12 months or less and instead, expense those costs on a straight-line basis over the lease term, or in the period in which the obligation is incurred, if such costs are variable. Adoption Impact – Lessor Accounting There was no impact to our financial statements as a result of adopting ASC Topic 842. ASU 2018-11, “Leases (Topic 842) – Targeted Improvements” Refer to Note 6 – “Leases” for further details on our lease arrangements as a lessee and lessor.

Durable virtual items accounted for 76% of online game revenue in the three months ended September 30, 2019 and 58% of online game revenue in the same period of the prior year. Consumable virtual items accounted for 24% of online game revenue in the three months ended September 30, 2019 and 42% of online game revenue in the same period of the prior year. The estimated weighted-average life of durable virtual items was 9 months Durable virtual items accounted for 72% of online game revenue in the nine months ended September 30, 2019 and 55% of online game revenue in the same period of the prior year. Consumable virtual items accounted for 28% of online game revenue in the nine months ended September 30, 2019 and 45% of online game revenue in the same period of the prior year. The estimated weighted average life of durable virtual items was 9 months Contract Balances We receive payments from our customers based on the payment terms established in our contracts. Payments for online game revenue are required at time of purchase, are non-refundable and relate to non-cancellable contracts that specify our performance obligations. Such payments are initially recorded to deferred revenue and are recognized into revenue as we satisfy our performance obligations. Further, payments made by our players are collected by payment processors and remitted to us generally within 30 days. Our right to the payments collected on our behalf are unconditional and therefore recorded as accounts receivable, net of the associated payment processing fees. Payments for advertising arrangements are due based on the contractually stated payment terms. The contract terms generally require payment within 30 to 60 days subsequent to the end of the month. Our right to payment from the customer is unconditional and therefore recorded as accounts receivable. During the three and nine months ended September 30, 2019, we recognized $19.9 million and $187.7 million, respectively, of revenue that was included in the current deferred revenue balance on December 31, 2018. The increase in accounts receivable, net during the nine months ended September 30, 2019 was primarily driven by sales on account during the period exceeding cash collections of current period and previously due amounts, supplemented by an increase in accounts receivable related to the acquisition of Small Giant Games Oy (“Small Giant”) . The incr ease in deferred revenue during the nine months ended September 30, 2019 was primarily driven by the sale of virtual items during the period exceeding revenue recognized from the satisfaction of our performance obligations, which includes the contributio n from Small Giant. Unsatisfied Performance Obligations Substantially all of our unsatisfied performance obligations relate to contracts with an original expected length of one year or less.

As of September 30, 2019, we did not consider any of our short-term or long-term investments to be other-than-temporarily impaired. We do not intend to sell, nor do we believe it is more likely than not that we will be required to sell, any of the securities in an unrealized loss position. When evaluating our investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer, our ability and intent to hold the security to maturity and whether it is more likely than not that we will be required to sell the investment before recovery of the amortized cost basis.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements Our financial assets consist of cash equivalents, short-term and long-term investments and accounts receivable, net. Cash equivalents, short-term investments and long-term investments, which consist of money market funds, corporate debt securities, U.S. government and government agency debt securities and certificates of deposit and time deposits Our financial liabilities consist of accounts payable and accrued liabilities, contingent consideration obligations and our debt. Accounts payable and accrued liabilities are stated at the invoiced or estimated payout amount, respectively, and approximate fair value. Contingent consideration obligations, which are the result of business acquisitions, are reported at fair value. With respect the fair value of our debt, refer to Note 10 – “Debt” for further discussion. As of September 30, 2019, our contingent consideration obligations represent the estimated fair value of the additional consideration payable in connection with our acquisitions of Gram Games in the second quarter of 2018 and Small Giant in the first quarter of 2019. Under the terms of the Gram Games acquisition, contingent consideration may be payable based on the achievement of certain future profitability performance targets during each annual period following the acquisition date for a total of three years, with no maximum limit as to the contingent consideration achievable. We estimated the acquisition date and subsequent reporting period fair values of the contingent consideration obligation using a Monte Carlo simulation. The significant unobservable inputs used in the fair value measurement of the contingent consideration obligation were Gram Games’ projected performance, a risk-adjusted discount rate and performance volatility similar to industry peers. Changes to projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future. As of December 31, 2018, the estimated fair value of the Gram Games contingent consideration obligation was $49.0 million. As of September 30, 2019, the estimated fair value of the contingent consideration obligation increased to $70.8 million, primarily due to stronger than expected performance and the increased probability of achievement and partially offset by a payment of $28.5 million to the former owners of Gram Games’ for its performance during the first annual earnout period. For the three and nine months ended September 30, 2019, we recognized $26.5 million and $50.3 million, respectively, of expense within research and development expenses in our consolidated statement of operations. Under the terms of the Small Giant acquisition, contingent consideration may be payable based on the achievement of certain future profitability performance targets during each annual period following the acquisition date for a total of three years, with no maximum limit as to the contingent consideration achievable. We estimated the acquisition date and subsequent reporting period fair values of the contingent consideration obligation using a Monte Carlo simulation. The significant unobservable inputs used in the fair value measurement of the contingent consideration obligation were Small Giant’s projected performance, a risk-adjusted discount rate and performance volatility similar to industry peers. Changes to projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future. At acquisition, the estimated fair value of the contingent consideration obligation was $98.0 million. As of September 30, 2019, the estimated fair value of the contingent consideration obligation increased to $217.9 million, primarily due to stronger than expected performance and the increased probability of achievement. Accordingly, for the three and nine months ended September 30, 2019, we recognized $34.3 million and $119.9 million, respectively, of expense within research and development expenses in our consolidated statement of operations. We estimate fair value as the exit price, which represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between knowledgeable and willing market participants. The valuation techniques used to measure the fair value of the Company’s financial instruments, all of which have counterparties with high credit ratings, were valued based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data. We use a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Includes inputs, other than Level 1 inputs, that are directly or indirectly observable in the marketplace. Level 3 — Unobservable inputs that are supported by little or no market activity. The composition of our financial assets and liabilities as of September 30, 2019 and December 31, 2018 among the three levels of the fair value hierarchy are as follows (in thousands): September 30, 2019 Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 128,189 $ — $ — $ 128,189 Corporate debt securities — 179,784 — 179,784 Certificates of deposit and time deposits — 1,831 — 1,831 Short-term investments: Corporate debt securities — 680,813 — 680,813 U.S. government and government agency debt securities — 107,992 — 107,992 Certificates of deposit and time deposits — 1,971 — 1,971 Long-term investments: Corporate debt securities — 8,041 — 8,041 U.S. government and government agency debt securities — 57,977 — 57,977 Total financial assets $ 128,189 $ 1,038,409 $ — $ 1,166,598 Liabilities: Contingent consideration $ — $ — $ 288,700 $ 288,700 December 31, 2018 Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 565 $ — $ — $ 565 Corporate debt securities — 4,987 — 4,987 Short-term investments: Corporate debt securities — 36,232 — 36,232 Total financial assets $ 565 $ 41,219 $ — $ 41,784 Liabilities: Contingent consideration $ — $ — $ 49,000 $ 49,000 The following table presents the activity for the nine months ended September 30, 2019 related to our Level 3 liabilities (in thousands): Level 3 Liabilities: Total Contingent consideration obligation – December 31, 2018 $ 49,000 Additions 98,000 Fair value adjustments 170,164 Payments (28,464 ) Contingent consideration obligation – September 30, 2019 $ 288,700 We had no transfers between valuation levels from December 31, 2018 to September 30, 2019.

In connection with the Building Sale, the Company de-recognized the related land, building and building improvements and all lessor related assets and liabilities, which resulted in a gain of $314.2 million within other income (expense), net in our consolidated statement of operations.

Leases [Abstract]
Leases	6. Leases Lessee Arrangements We determine if an arrangement is a lease at contract inception. If there is an identified asset in the contract (either explicitly or implicitly) and we have control over its use, the contract is (or contains) a lease. In determining if there is an identified asset, we apply judgment in assessing whether the supplier has a substantive substitution right based on the supplier’s practical ability to substitute the asset and the economic benefit to do so. If it is determined that a substantive substitution right exists, the contract is not a lease and is not accounted for under ASC Topic 842. With the respect to the servers utilized in certain of our hosting and data storage arrangements, the Company determined that a substantive substitution right existed given the location of the servers at the supplier’s premises, a lack of contractual restrictions preventing the supplier from substituting the servers throughout the period of use and the economic incentive for the supplier to substitute the servers as needed in order to efficiently handle varying levels of demand from its various customers. In connection with the Building Sale, the Company executed a leaseback of approximately 185,000 square feet of the Building over a 12-year term, where we expect to continue operating our headquarters. The agreement provides the Company two separate options to extend the lease for eight years each and a third option to extend the lease for six years (for a total of an additional 22 years). At lease inception, the Company determined it was not reasonably certain to exercise any of the options to extend. The net initial base rent will be approximately $10.7 million for the first year of the lease and may increase by an annual amount not to exceed 3.25% per year. Our remaining operating leases are also primarily for office facilities. Certain leases include options to extend the lease for a set number of years or early terminate the lease prior to the contractually defined expiration date. We include such extension periods in the lease term only when it is reasonably certain that they will be exercised and include such periods beyond the early termination date when it is reasonably certain the early terminations will not be exercised. As of September 30, 2019, the weighted-average remaining lease term for our operating leases was 10.1 years. We record right-of-use assets, current operating lease liabilities and non-current operating lease liabilities in our consolidated balance sheet for operating leases with lease terms greater than 12 months. We have elected not to apply the balance sheet recognition requirements to leases with lease terms of 12 months or less (“short-term leases”). Additionally, we do not separate lease components from non-lease components and therefore allocate the entire consideration to the lease component(s). Right-of-use assets represent our right to use an underlying asset during the lease term and operating lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and operating lease liabilities are recognized at the lease commencement date based on the present value of the total required fixed payments over the lease term, with the right-of-use assets further adjusted for any payments made prior to lease commencement, lease incentives received and/or initial direct costs incurred. Certain lease arrangements also include variable payments for costs such as common-area maintenance, utilities, taxes or other operating costs, which are based on a percentage of actual expenses incurred or a fluctuating rate which is unknown at the inception of the contract. These variable lease payments are excluded from the measurement of the lease liability. In determining the present value of lease payments, we discount future lease payments using our incremental borrowing rate since the implicit rate in our various leases is unknown. The incremental borrowing rate is determined at lease commencement for each individual lease and is based on a number of factors, including relevant observable debt transactions, the current economic environment, lease term and currency in which the lease is denominated. As of September 30, 2019, the weighted-average incremental borrowing rate for our operating leases was 4.4%. We recognize lease expense for operating leases and short-term leases on a straight-line basis over the lease term. Variable lease payments are recognized when the underlying uncertainty is resolved, which is generally when the obligation for those costs are incurred. These expenses are presented as operating expenses in the consolidated statement of operations. For the three and nine months ended September 30, 2019, the components of lease expense were as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2019 Operating lease expense $ 5,237 $ 9,101 Variable lease expense 1,608 2,751 Total lease expense (1) $ 6,845 $ 11,852 (1) The expense associated with short-term leases with a lease term of greater than one month was not material for the three and nine months ended September 30, 2019. For the three and nine months ended September 30, 2019, supplemental cash and noncash information related to operating leases, excluding any transition adjustments, were as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2019 Fixed operating lease payments $ 6,523 $ 11,241 Right-of-use assets obtained in exchange for operating lease liabilities (noncash) 125,776 136,966 As of September 30, 2019, future lease payments related to our operating leases were as follows (in thousands): Year ending December 31: Operating Leases Remaining 2019 $ 5,461 2020 21,189 2021 20,297 2022 16,709 2023 16,143 2024 13,844 Thereafter 90,955 Total lease payments 184,598 Less: Imputed interest (37,095 ) Total lease liability balance $ 147,503 We do not have any leases that have not yet commenced that create significant rights and obligations as of September 30, 2019. During the third quarter of 2018, we executed an assignment of our Oxford office lease associated with our fourth quarter 2017 restructuring plan. The original lease term ends in November 2022, with a lessee option to early terminate in November 2019. All terms under the original lease were assigned in full to the assignee, with the assignee becoming primarily liable to make rental payments directly to the landlord. Further, the assignee was required to provide the landlord a security deposit equal to twelve months rent to be used by the landlord in the event of the assignee’s non-performance. In connection with the assignment, the Company became secondarily liable in the event the assignee is unable to perform under the lease. Based on the current rent and related payments, the maximum exposure to the Company is estimated to be $1.7 million as of September 30, 2019. However, the lease is subject to periodic rate reviews which allow the landlord to make market adjustments to the rent and other related payments and accordingly, the maximum exposure may be greater than this amount. As of September 30, 2019, the estimated fair value of this guarantee is not material. Lessor Arrangements As noted previously, prior to July 1, 2019, we owned the building where our San Francisco headquarters is located and had operating lease arrangements with various third-party tenants for the remaining available office space. However, in connection the Building Sale, effective July 1, 2019, the Company sold all preexisting leases between the Company and its tenants to the buyer. As a result, all lessor related assets and liabilities were de-recognized upon closing. We do not separate lease components from non-lease components and therefore allocate the entire consideration in our contracts to the lease components. All of the lease and non-lease components qualify for accounting under ASC Topic 842. For the nine months ended September 30, 2019 the components of lease income were as follows (in thousands): Nine Months Ended September 30, 2019 Operating lease income $ 10,563 Variable lease income 1,103 Total lease income $ 11,666

Business Combinations [Abstract]
Acquisitions	7. Acquisitions Small Giant Acquisition On January 2, 2019, we acquired 80% of all issued and outstanding share capital (including all rights to acquire share capital) of Small Giant, a Finnish Company, to expand our live service portfolio and new game pipeline, for total purchase consideration of $715.5 million. The remaining 20% will be acquired ratably for potential additional cash consideration payable annually based upon the achievement of specified profitability metrics by Small Giant during each of the three years following the closing. The equity rights and privileges of the remaining Small Giant shareholders lack the traditional rights and privileges associated with equity ownership and accordingly, the transaction is accounted for as if the Company acquired 100% of Small Giant on the acquisition date. The future payments associated with Zynga’s acquisition of the remaining 20% represent a contingent consideration obligation. In the third quarter of 2019, we made an additional payment of $2.4 million related to customary closing working capital adjustments, bringing the total purchase consideration to $717.9 million. The total purchase consideration – including the third quarter 2019 working closing capital adjustment – included $336.0 million in cash, $30.0 million of cash that was deposited into an escrow account for a period of 18 months as security for general representations and warranties, 63,794,746 shares of our Class A common stock valued at $253.9 million at the acquisition date and contingent consideration of $98.0 million at the acquisition date. We will record changes in the fair value of the contingent consideration within our consolidated statement of operations in each future reporting period as they occur (see Note 4 – “Fair Value Measurements” for further discussion on this estimate). Additionally, in connection with the transaction, the Company executed noncompetition agreements with the management of Small Giant for a term of three years following the acquisition date. However, the acquisition date estimated fair value of the noncompetition agreements was not material. The following table summarizes the acquisition date fair value of the tangible assets, intangible assets, liabilities assumed, contingent consideration payable and related goodwill acquired from Small Giant (in thousands): Total Cash $ 34,193 Accounts receivable, net 22,974 Prepaid expenses 2,561 Intangible assets, net: Developed technology, useful life of 5 years 155,000 Trade names, useful life of 7 years 32,000 Goodwill 531,748 Property and equipment, net 180 Right-of-use assets 883 Other non-current assets 120 Total assets acquired 779,659 Accounts payable (1,716 ) Income tax payable (5,623 ) Operating lease liabilities (380 ) Other current liabilities (16,126 ) Deferred tax liabilities, net (37,400 ) Non-current operating lease liabilities (503 ) Total liabilities (61,748 ) Total purchase price consideration $ 717,911 Fair value of Zynga Stock Consideration (1) (253,903 ) Non-current contingent consideration payable (98,000 ) Total cash consideration $ 366,008 (1) The fair value of our intangible assets, net was determined using a risk-adjusted, discounted cash flow model. Certain amounts noted above are preliminary and subject to change during the respective measurement period (up to one year from the acquisition date) as we obtain additional information for the preliminary fair value estimates of the assets acquired and liabilities assumed. The primary preliminary estimates that are not yet finalized relate to certain tangible assets and liabilities assumed, identifiable intangible assets, income and non-income based taxes and residual goodwill. Goodwill, which is non-deductible for tax purposes, represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired and is primarily attributable to the assembled workforce of the acquired business and expected synergies at the time of the acquisition. The weighted-average amortization period of the acquired intangible assets was 5.3 years at acquisition. The results of operations from Small Giant have been included in our consolidated statement of operations since the date of acquisition. During the three and nine months ended September 30, 2019, Small Giant represented $62.4 million and $112.3 million of our total revenue, respectively, and reduced our consolidated net income with $6.6 million and $77.8 million of net losses, respectively. Transaction costs incurred by the Company in connection with the Small Giant acquisition, including transfer taxes and professional fees, were $7.6 million for the nine months ended September 30, 2019 and were recorded within general and administrative expenses in our consolidated statements of operations. The following table summarizes the p ro forma consolidated information of the Company assuming the acquisition of Small Giant had occurred as of January 1, 2018. The unaudited pro forma information for all periods presented includes the business combination accounting effects resulting from t he acquisition, including amortization for intangible assets acquired, depreciation expense for tangible assets acquired, and recognition of tax benefits primarily related to the amortization of the intangible asset deferred tax liability. The unaudited pr o forma financial information as presented below is for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of 2018.

Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes On a consolidated basis, the provision for income taxes increased $9.9 million in the three months ended September 30, 2019 compared to the same period of the prior year. The increase was primarily attributable to a net increase in income tax as a result of the Building Sale and an increase in expense related to the Base Erosion and Anti-Abuse Tax (“BEAT”). During the nine months ended September 30, 2019, the benefit from income taxes was $3.2 million and during the nine months ended September 30, 2018, the provision for income taxes was $6.2 million, resulting a net change of $9.4 million. The net change was primarily attributable to a benefit generated from the post-acquisition statutory operating losses from Small Giant and a change in our jurisdictional mix of earnings, partially offset by an increase in expense related to BEAT and income tax as a result of the Building Sale.

Debt

Debt Disclosure [Abstract]
Debt	10. Debt Convertible Senior Notes On June 14, 2019, we issued $690.0 million aggregate principal amount of 0.25% Convertible Senior Notes due 2024 (the “Notes”), including the initial purchasers’ exercise in full of their option to purchase an additional $90.0 million principal amount of the Notes, in a private placement to qualified institutional buyers in an offering exempt from registration under the Securities Act. The net proceeds from the issuance of the Notes was $672.2 million after deducting transaction costs. The Notes are governed by an indenture (the “Indenture”) between us, as the issuer, and Wells Fargo Bank, National Association, as trustee. The Notes are senior unsecured obligations and rank senior in right of payment to all of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to all of our existing and future liabilities that are not so subordinated; effectively junior to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities of our current or future subsidiaries (including trade payables). The Indenture does not contain any financial covenants. The Notes mature on June 1, 2024 unless earlier converted, redeemed or repurchased in accordance with their term prior to the maturity date. Interest is payable semiannually in arrears on June 1 and December 1 of each year, beginning on December 1, 2019. The Notes have an initial conversion rate of 120.3695 shares of our Class A common stock per $1,000 principal amount of Notes, which is equal to an initial conversion price of approximately $8.31 per share of our Class A common stock and is subject to adjustment in certain events. Following certain corporate events that occur prior to the maturity date or following our issuance of a notice of redemption, we will increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or during the related redemption period in certain circumstances. Additionally, upon the occurrence of a corporate event that constitutes a “fundamental change” per the Indenture, holders of the Notes may require us to repurchase for cash all or a portion of their Notes at a purchase price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest. Prior to the close of business on the business day immediately preceding March 1, 2024, the Notes will be convertible only under the following circumstances: • during any calendar quarter commencing after September 30, 2019, if the last reported sale price of our Class A common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five business-day period after any five consecutive trading-day period in which the trading price per $1,000 principal amount of Notes for such trading day was less than 98% of the product of the last reported sale price of our Class A common stock and the conversion rate on each such trading day; • if we call the Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or • upon the occurrence of specified corporate events described in the Indenture. On or after March 1, 2024, holders of the Notes may convert all or any portion of their Notes regardless of the foregoing conditions. Upon any conversion, holders will receive cash, shares of our Class A common stock or a combination of cash and shares of our Class A common stock, at our election. The Company may not redeem the Notes prior to June 5, 2022. On or after June 5, 2022, the Company may redeem for cash all or any portion of the Notes, at its option, if the last reported sale price of our Class A common stock has been at least 130% of the conversion price for at least 20 trading days during any 30 consecutive trading-day period ending on the immediately preceding date when the Company provides a notice of redemption. The redemption price is equal to 100% of the principal amount of the Notes to be redeemed, plus any accrued and unpaid interest. As of September 30, 2019, the conditions allowing holders of the Notes to convert have not been met and therefore the Notes are not yet convertible. We separately accounted for the liability and equity components of the Notes. We determined the initial carrying amount of the $572.0 million liability component by calculating the present value of the cash flows using an effective interest rate of 4.1%. The interest rate was determined based on non-convertible debt offerings of similar sizes and terms by companies with similar credit ratings (Level 2 inputs). The carrying amount of the equity component, representing the conversion option, was $118.0 million and was calculated by deducting the initial carrying value of the liability component from the principal amount of the Notes as a whole. This difference represents a debt discount that is amortized to interest expense over the 5-year contractual term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. We allocate transaction costs related to the issuance of the Notes to the liability and equity components using the same proportions as the initial carrying value of the Notes. Transaction costs initially attributable to the liability component were $14.8 million and are being amortized to interest expense using the effective interest method over the term of the Notes. Transaction costs attributable to the equity component were $3.1 million and are accounted for consistently with the equity component of the debt. The net carrying amount of the liability and equity components of the Notes was as follows (in thousands): September 30, 2019 Liability component: Principal $ 690,000 Unamortized debt discount (111,686 ) Unamortized transaction costs (14,005 ) Net carrying amount $ 564,309 Equity component, net of transaction costs $ 114,938 Interest expense recognized related to the Notes was as follows (in thousands): Three Months Ended September 30, 2019 Nine Months Ended September 30, 2019 Contractual interest expense $ 431 $ 504 Amortization of debt discount 5,408 6,304 Amortization of transaction costs 678 790 Total $ 6,517 $ 7,598 As of September 30, 2019, the estimated fair value of the Notes was $687.0 million. We estimated the fair value based on the quoted market prices in an inactive market on the last trading day of the reporting period, which are considered Level 2 inputs. Capped Call Transactions In connection with the offering of the Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (collectively, the “Capped Calls”). The Capped Calls have an initial strike price of approximately $8.31 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have an initial cap price of $12.54 per share, subject to certain adjustments. The Capped Calls are generally intended to reduce or offset the potential economic dilution of approximately 83.1 million shares to our Class A common stock upon any conversion of the Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. As the Capped Calls are considered indexed to our own stock and are equity classified, they are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $73.8 million incurred in connection with the Capped Calls was recorded as a reduction to additional paid-in capital. Convertible Senior Notes and Capped Call Transactions – Impact on Earnings per Share The 83.1 million shares underlying the conversion option of the Notes will not have an impact on our diluted earnings per share until the average market price of our Class A common stock exceeds the conversion price of $8.31 per share, as we intend and have the ability to settle the principal amount of the Notes in cash upon conversion. The Company computes the potentially dilutive impact of the shares of Class A common stock related to the Notes using the treasury stock method. Capped Calls are excluded from the calculation of diluted earnings per share, as they would be antidilutive under the treasury stock method. Credit Facility In December 2018, the Company entered into a credit agreement (the “Credit Agreement”) with Bank of America, N.A. that provides for a three-year revolving credit facility (the “Credit Facility”) in an initial aggregate principal amount of up to $200.0 million and is secured by a blanket lien on the Company’s assets, excluding the Company’s San Francisco corporate headquarters. In connection with the Building Sale and consistent with the terms of the Credit Facility, the borrowing capacity was reduced to $150.0 million on July 1, 2019. The Company may borrow, repay and re-borrow funds under the Credit Agreement until the third anniversary of the closing date, at which time the Credit Facility will terminate, and all outstanding revolving loans, together with all accrued and unpaid interest, must be repaid. Finally, the Company may use the proceeds of future borrowings under the Credit Facility for general corporate purposes. At the Company’s option, revolving loans accrue interest at a per annum rate based on either (i) the base rate plus a margin ranging from 0.50% to 1.00%, determined based on the Company’s consolidated leverage ratio for the four most recent fiscal quarters (the “Consolidated Leverage Ratio”) or (ii) the LIBOR rate (for interest periods of one, two, three or six months) plus a margin ranging from 1.50% to 2.00%, determined based on the Company’s Consolidated Leverage Ratio (“LIBOR Loan”). The base rate is defined as the highest of (i) the federal funds rate, plus 0.50%, (ii) Bank of America, N.A.’s prime rate and (iii) the LIBOR rate for a one-month interest period plus 1.00%. The Company is also obligated to pay an ongoing commitment fee on undrawn amounts at a rate ranging from 0.25% to 0.35%, determined based on the Company’s Consolidated Leverage Ratio. As of September 30, 2019, we had no amounts outstanding under the Credit Facility. Debt issuance costs associated with the Credit Facility were capitalized and will amortize on a straight-line basis over the three-year term of the Credit Agreement, with the expense recorded to interest expense in our consolidated statement of operations.

The timing and amount of any stock repurchase will be determined based on market conditions, share price and other factors. The program does not require us to repurchase any specific number of shares of our Class A common stock and may be modified, suspended or terminated at any time without notice. The 2018 Share Repurchase Program will be funded from existing cash on hand or other sources of funding as the Company may determine to be appropriate. Share repurchases under these authorizations may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades, accelerated share repurchase transactions, purchases through 10b5-1 plans or by any combination of such methods. During the three and nine months ended September 30, 2019, no share repurchases were made under the 2018 Share Repurchase Program. As of September 30, 2019, we had $173.8 million remaining under the 2018 Share Repurchase Program. In November 2016, we announced that our Board of Directors authorized a share repurchase program allowing us to repurchase up to $200.0 million of our outstanding shares of Class A common stock (“2016 Share Repurchase Program”). In 2018, we completed the 2016 Share Repurchase Program by repurchasing 18.2 million shares of our Class A common stock at a weighted-average price of $3.59 per share for a total of $65.4 million. All of our stock repurchases were made through open market purchases under Rule 10b5-1 plans and subsequently retired.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	14. Net Income (Loss) Per Share of Common Stock On May 2, 2018, our founder, Mark Pincus, elected to convert certain outstanding shares of Class B common stock and all outstanding shares of Class C common stock controlled by Mr. Pincus and an affiliated investment entity into an equivalent number of shares of Class A common stock. As a result of Mr. Pincus’ conversion, the remaining shares of Class B common stock represented less than 10% of the total voting power of all Zynga stockholders and, accordingly, each remaining outstanding share of Class B common stock automatically converted into one share of Class A common stock. Each Zynga stockholder now has one vote per share on all matters subject to stockholder vote. Following the conversion, no shares of Class B or Class C common stock are outstanding and the total number of authorized shares of capital stock will be reduced to account for the elimination of the Class B and Class C common stock. Accordingly, beginning in the second quarter of 2018, the Company calculated basic and dilutive net income (loss) per share under a single-class method. Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net i ncome (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive securities. In computing diluted net income (loss) per share, net income (loss) attributable to common shareholders i s re-allocated to reflect the potential impact of dilutive securities, including stock options, unvested ZSUs, unvested performance-based ZSUs and ESPP withholdings. For periods in which we have generated a net loss or there is no income attributable to co mmon stockholders, we do not include dilutive securities in our calculation of diluted net income (loss) per share, as the impact of these awards is anti-dilutive. The following tables set forth the computation of basic and diluted net income (loss) per share of common stock (in thousands, except per share data): Three Months Ended September 30, Three Months Ended September 30, 2019 2018 BASIC: Net income (loss) attributable to common stockholders $ 230,083 $ 10,200 Weighted-average common shares outstanding 943,350 860,988 Net income (loss) per share attributable to common stockholders $ 0.24 $ 0.01 DILUTED: Net income (loss) attributable to common stockholders – basic $ 230,083 $ 10,200 Weighted-average common shares outstanding – basic 943,350 860,988 Weighted-average effect of dilutive securities: Stock options and employee stock purchase plan 11,854 11,871 ZSUs 18,626 13,434 Performance-based ZSUs — 935 Weighted-average common shares outstanding – diluted 973,830 887,228 Net income (loss) per share attributable to common stockholders – diluted $ 0.24 $ 0.01 Nine Months Ended September 30, Nine Months Ended September 30, 2019 2018 (1) BASIC: Net income (loss) attributable to common stockholders – basic $ 45,425 $ 14,898 Weighted-average common shares outstanding – basic 935,701 863,062 Net income (loss) per share attributable to common stockholders – basic $ 0.05 $ 0.02 DILUTED: Net income (loss) attributable to common stockholders – basic $ 45,425 $ 14,898 Weighted-average common shares outstanding – basic 935,701 863,062 Weighted-average effect of dilutive securities: Stock options and employee stock purchase plan 12,941 11,051 ZSUs 22,159 15,098 Performance-based ZSUs — 935 Weighted-average common shares outstanding – diluted 970,801 890,146 Net income (loss) per share attributable to common stockholders – diluted $ 0.05 $ 0.02 (1) The following weighted-average equity awards were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Stock options and employee stock purchase plan 4,647 7,792 3,405 5,702 ZSUs 390 1,164 715 6,066 Total 5,037 8,956 4,120 11,768

Commitments and Contingencies	15. Commitments and Contingencies The amounts represented in the tables below reflect our minimum cash obligations for the respective calendar years based on contractual terms, but not necessarily the periods in which these costs will be expensed in the Company’s consolidated statement of operations. Licensor and Marketing Commitments We have entered into several contracts with licensors that contain minimum contractual and marketing commitments that may not be dependent on any deliverables. As of September 30, 2019, future minimum contractual royalty payments due to licensors and marketing commitments for the licensed products are as follows (in thousands): Year ending December 31: Remaining 2019 $ 14,336 2020 40,522 2021 160 2022 — 2023 10,000 Thereafter — Total $ 65,018 Other Purchase Commitments We have entered into several contracts primarily for hosting of data systems and other services. As of September 30, 2019, future minimum purchase commitments that have initial or remaining non-cancelable terms are as follows (in thousands): Year ending December 31: Remaining 2019 $ 3,618 2020 22,503 2021 15,958 2022 49 Thereafter — Total $ 42,128 Excluded from tables above is our uncertain income tax position liability of $15.3 million, which includes interest and penalties, as the Company cannot make a reasonably reliable estimate of the period of cash settlement. Legal Matters The Company is involved in legal and regulatory proceedings on an ongoing basis. Some of these proceedings are in early stages and may seek an indeterminate amount of damages. If the Company believes that a loss arising from such matters is probable and can be reasonably estimated, the Company accrues the estimated liability in its financial statements. If only a range of estimated losses can be determined, the Company accrues an amount within the range that, in its judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, the Company accrues the low end of the range. For proceedings in which an unfavorable outcome is reasonably possible but not probable and an estimate of the loss or range of losses arising from the proceeding can be made, the Company discloses such an estimate, if material. If such a loss or range of losses is not reasonably estimable, the Company discloses that fact. In assessing the materiality of a proceeding, the Company evaluates, among other factors, the amount of monetary damages claimed, as well as the potential impact of non-monetary remedies sought by plaintiffs that may require changes to business practices in a manner that could have a material adverse impact on the Company’s business. On September 12, 2019, we announced that an incident had occurred that may have involved player data (the “Data Incident”). Upon our discovery of the Data Incident, an investigation immediately commenced and advisors and third-party forensics firms were retained to assist. Our current belief is that, during the third quarter of 2019, outside hackers may have illegally accessed certain player account information and other Zynga information, and that no financial information was accessed. We have provided notifications to players, investors, regulators and other third parties, where we believe notice was required or appropriate. At this time, we are unable to estimate the loss or range of loss, if any, arising from this matter. The Company is, at various times, also party to various other legal proceedings and claims not previously discussed which arise in the ordinary course of business. In addition, the Company may receive notifications alleging infringement of patent or other intellectual property rights. Adverse results in any such litigation, legal proceedings or claims may include awards of substantial monetary damages, expensive legal fees, costly royalty or licensing agreements, or orders preventing us from offering certain games, features, or services, and may also result in changes in the Company’s business practices, which could result in additional costs or a loss of revenue and could otherwise harm the Company’s business. Although the results of such litigation cannot be predicted with certainty, the Company believes that the amount or range of reasonably possible losses related to such pending or threatened litigation will not have a material adverse effect on its business, operating results, cash flows, or financial condition should such litigation be resolved unfavorably.

Overview and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying interim consolidated financial statements are presented in accordance with United States generally accepted accounting principles (“U.S. GAAP”). The interim consolidated financial statements include the operations of the Company and its owned subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation. The accompanying interim consolidated financial statements and these related notes should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2018.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying interim consolidated balance sheets as of September 30, 2019 and December 31, 2018, the interim consolidated statements of operations, statements of comprehensive income (loss) and statements of stockholders’ equity for the three and nine months ended September 30, 2019 and 2018, the statements of cash flows for the nine months ended September 30, 2019 and 2018 and the notes to interim consolidated financial statements are unaudited. These unaudited interim consolidated financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited interim consolidated financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s statement of financial position and operating results for the periods presented. The results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results expected for the full fiscal year or any other future period.
Use Of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the interim consolidated financial statements and notes thereto. Significant estimates and assumptions reflected in the financial statements include, but are not limited to, the estimated average playing period of payers that we use for revenue recognition, useful lives of property and equipment and intangible assets, accrued liabilities, income taxes, the fair value of assets and liabilities acquired through business combinations, contingent consideration obligations, the discount rate used in discounting our operating lease liabilities, the interest rate used in calculating the present value of the initial liability component of our convertible notes, stock-based compensation expense and evaluation of recoverability of goodwill, intangible assets, and long-lived assets. Actual results could differ materially from those estimates. For the three and nine months ended September 30, 2019, there was no significant impact from discontinued games or from changes in our estimated average playing period of payers that required adjusting the recognition period of deferred revenue generated in prior periods. For the nine months ended September 30, 2018, we recognized $0.9 million of online game revenue and income from operations from games that have been discontinued as there is no further performance obligation. This change in estimate did not impact our reported earnings per share in the nine months ended September 30, 2018. For the three months ended September 30, 2018, there were no discontinued games that required adjusting the recognition period of deferred revenue generated in prior periods. Further, there were no changes in our estimated average playing period of payers that required adjusting the recognition period of deferred revenue generated in prior periods for the three and nine months ended September 30, 2018.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued But Not Yet Adopted In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” ASC Topic 350-40, Internal-Use Software Issued And Adopted In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” “Leases (Topic 842) – Targeted Improvements” Adoption Impact – Lessee Accounting The adoption of ASC Topic 842 on January 1, 2019 resulted in the recognition of right-of-use assets of $9.1 million, which includes the elimination of our remaining prepaid rent and deferred rent balances, current operating lease liabilities of $7.6 million and non-current operating lease liabilities of $12.4 million. The adoption of ASC Topic 842 did not impact our consolidated statement of operations or consolidated statement of cash flows. ASC Topic 842 also amends the provisions of ASC Topic 420 – Exit or Disposal Obligations ASC 360 – Property, Plant, and Equipment As part of the adoption, the new standard allows a number of practical expedients and exemptions. At transition, we elected the following: • The package of practical expedients, which allows us to carryforward our historical lease classification, assessment of whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard; • The practical expedient to not separate non-lease components from the related lease components; and • The exemption to not apply the balance sheet recognition requirements for leases with a lease term of 12 months or less and instead, expense those costs on a straight-line basis over the lease term, or in the period in which the obligation is incurred, if such costs are variable. Adoption Impact – Lessor Accounting There was no impact to our financial statements as a result of adopting ASC Topic 842. ASU 2018-11, “Leases (Topic 842) – Targeted Improvements” Refer to Note 6 – “Leases” for further details on our lease arrangements as a lessee and lessor.
Acquisition Related Contingent Consideration / Fair Value Measures Liabilities	Under the terms of the Gram Games acquisition, contingent consideration may be payable based on the achievement of certain future profitability performance targets during each annual period following the acquisition date for a total of three years, with no maximum limit as to the contingent consideration achievable. We estimated the acquisition date and subsequent reporting period fair values of the contingent consideration obligation using a Monte Carlo simulation. The significant unobservable inputs used in the fair value measurement of the contingent consideration obligation were Gram Games’ projected performance, a risk-adjusted discount rate and performance volatility similar to industry peers. Changes to projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future. As of December 31, 2018, the estimated fair value of the Gram Games contingent consideration obligation was $49.0 million. As of September 30, 2019, the estimated fair value of the contingent consideration obligation increased to $70.8 million, primarily due to stronger than expected performance and the increased probability of achievement and partially offset by a payment of $28.5 million to the former owners of Gram Games’ for its performance during the first annual earnout period. For the three and nine months ended September 30, 2019, we recognized $26.5 million and $50.3 million, respectively, of expense within research and development expenses in our consolidated statement of operations. Under the terms of the Small Giant acquisition, contingent consideration may be payable based on the achievement of certain future profitability performance targets during each annual period following the acquisition date for a total of three years, with no maximum limit as to the contingent consideration achievable. We estimated the acquisition date and subsequent reporting period fair values of the contingent consideration obligation using a Monte Carlo simulation. The significant unobservable inputs used in the fair value measurement of the contingent consideration obligation were Small Giant’s projected performance, a risk-adjusted discount rate and performance volatility similar to industry peers. Changes to projected performance of the acquired business could result in a higher or lower contingent consideration obligation in the future. At acquisition, the estimated fair value of the contingent consideration obligation was $98.0 million. As of September 30, 2019, the estimated fair value of the contingent consideration obligation increased to $217.9 million, primarily due to stronger than expected performance and the increased probability of achievement. Accordingly, for the three and nine months ended September 30, 2019, we recognized $34.3 million and $119.9 million, respectively, of expense within research and development expenses in our consolidated statement of operations.
Fair Value Measurements Investment	We estimate fair value as the exit price, which represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between knowledgeable and willing market participants. The valuation techniques used to measure the fair value of the Company’s financial instruments, all of which have counterparties with high credit ratings, were valued based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data. We use a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Includes inputs, other than Level 1 inputs, that are directly or indirectly observable in the marketplace. Level 3 — Unobservable inputs that are supported by little or no market activity.
Lessee Arrangements	We determine if an arrangement is a lease at contract inception. If there is an identified asset in the contract (either explicitly or implicitly) and we have control over its use, the contract is (or contains) a lease. In determining if there is an identified asset, we apply judgment in assessing whether the supplier has a substantive substitution right based on the supplier’s practical ability to substitute the asset and the economic benefit to do so. If it is determined that a substantive substitution right exists, the contract is not a lease and is not accounted for under ASC Topic 842. With the respect to the servers utilized in certain of our hosting and data storage arrangements, the Company determined that a substantive substitution right existed given the location of the servers at the supplier’s premises, a lack of contractual restrictions preventing the supplier from substituting the servers throughout the period of use and the economic incentive for the supplier to substitute the servers as needed in order to efficiently handle varying levels of demand from its various customers. In determining the present value of lease payments, we discount future lease payments using our incremental borrowing rate since the implicit rate in our various leases is unknown. The incremental borrowing rate is determined at lease commencement for each individual lease and is based on a number of factors, including relevant observable debt transactions, the current economic environment, lease term and currency in which the lease is denominated. As of September 30, 2019, the weighted-average incremental borrowing rate for our operating leases was 4.4%.
Debt	We separately accounted for the liability and equity components of the Notes. We determined the initial carrying amount of the $572.0 million liability component by calculating the present value of the cash flows using an effective interest rate of 4.1%. The interest rate was determined based on non-convertible debt offerings of similar sizes and terms by companies with similar credit ratings (Level 2 inputs). The carrying amount of the equity component, representing the conversion option, was $118.0 million and was calculated by deducting the initial carrying value of the liability component from the principal amount of the Notes as a whole. This difference represents a debt discount that is amortized to interest expense over the 5-year contractual term of the Notes using the effective interest rate method. The equity component is not remeasured as long as it continues to meet the conditions for equity classification.
Earnings Per Share	On May 2, 2018, our founder, Mark Pincus, elected to convert certain outstanding shares of Class B common stock and all outstanding shares of Class C common stock controlled by Mr. Pincus and an affiliated investment entity into an equivalent number of shares of Class A common stock. As a result of Mr. Pincus’ conversion, the remaining shares of Class B common stock represented less than 10% of the total voting power of all Zynga stockholders and, accordingly, each remaining outstanding share of Class B common stock automatically converted into one share of Class A common stock. Each Zynga stockholder now has one vote per share on all matters subject to stockholder vote. Following the conversion, no shares of Class B or Class C common stock are outstanding and the total number of authorized shares of capital stock will be reduced to account for the elimination of the Class B and Class C common stock. Accordingly, beginning in the second quarter of 2018, the Company calculated basic and dilutive net income (loss) per share under a single-class method. Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net i ncome (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive securities. In computing diluted net income (loss) per share, net income (loss) attributable to common shareholders i s re-allocated to reflect the potential impact of dilutive securities, including stock options, unvested ZSUs, unvested performance-based ZSUs and ESPP withholdings. For periods in which we have generated a net loss or there is no income attributable to co mmon stockholders, we do not include dilutive securities in our calculation of diluted net income (loss) per share, as the impact of these awards is anti-dilutive.
Legal Contingencies	The Company is involved in legal and regulatory proceedings on an ongoing basis. Some of these proceedings are in early stages and may seek an indeterminate amount of damages. If the Company believes that a loss arising from such matters is probable and can be reasonably estimated, the Company accrues the estimated liability in its financial statements. If only a range of estimated losses can be determined, the Company accrues an amount within the range that, in its judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, the Company accrues the low end of the range. For proceedings in which an unfavorable outcome is reasonably possible but not probable and an estimate of the loss or range of losses arising from the proceeding can be made, the Company discloses such an estimate, if material. If such a loss or range of losses is not reasonably estimable, the Company discloses that fact. In assessing the materiality of a proceeding, the Company evaluates, among other factors, the amount of monetary damages claimed, as well as the potential impact of non-monetary remedies sought by plaintiffs that may require changes to business practices in a manner that could have a material adverse impact on the Company’s business.
Legal Expenses	Legal expenses are recognized as incurred.

Earnings Per Share Diluted [Line Items]
Conversion of stock description		On May 2, 2018, our founder, Mark Pincus, elected to convert certain outstanding shares of Class B common stock and all outstanding shares of Class C common stock controlled by Mr. Pincus and an affiliated investment entity into an equivalent number of shares of Class A common stock. As a result of Mr. Pincus’ conversion, the remaining shares of Class B common stock represented less than 10% of the total voting power of all Zynga stockholders and, accordingly, each remaining outstanding share of Class B common stock automatically converted into one share of Class A common stock. Each Zynga stockholder now has one vote per share on all matters subject to stockholder vote. Following the conversion, no shares of Class B or Class C common stock are outstanding and the total number of authorized shares of capital stock will be reduced to account for the elimination of the Class B and Class C common stock. Accordingly, beginning in the second quarter of 2018, the Company calculated basic and dilutive net income (loss) per share under a single-class method.
