The Company, Basis of Presentation and Summary of Significant Accounting Policies
The Company, Basis of Presentation and Summary of Significant Accounting Policies	Note 1 — The Company, Basis of Presentation and Summary of Significant Accounting Policies Glu Mobile Inc. (the “Company” or “Glu”) was incorporated in Nevada in May 2001 and reincorporated in the state of Delaware in March 2007. The Company develops, publishes, and markets a portfolio of games designed for users of smartphones and tablet devices who download and make purchases within its games through direct-to-consumer digital storefronts, such as the Apple App Store, Google Play Store, Amazon Appstore and others (“Digital Storefronts”). The Company creates games based on its own original brands, as well as third-party licensed brands, properties and other content . Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 10, 2017. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, which the Company believes are necessary for a fair statement of the Company’s financial position as of March 31, 2017 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2017 and 2016, respectively. These unaudited condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year. The unaudited condensed consolidated balance sheet presented as of December 31, 2016 has been derived from the audited consolidated financial statements as of that date, and the unaudited condensed consolidated balance sheet presented as of March 31, 2017 has been derived from the unaudited condensed consolidated financial statements as of that date. Certain prior year balances have been reclassified to conform to the current year presentation. Such reclassifications did not affect revenue, operating loss, net loss, cash flows, total assets, total liabilities or stockholders’ equity. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable. The Company derives its accounts receivable from revenue earned from customers or through Digital Storefronts located in the United States and other locations outside of the United States. The Company performs ongoing credit evaluations of its customers’ and the Digital Storefronts’ financial condition and, generally, requires no collateral from its customers or the Digital Storefronts. The Company bases its allowance for doubtful accounts on management’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews past due balances over a specified amount individually for collectability on a monthly basis. It reviews all other balances quarterly. The Company charges off accounts receivable balances against the allowance when it determines that the amount will not be recovered. The following table summarizes the revenue from customers or aggregate purchases through Digital Storefronts in excess of 10% of the Company’s revenue: Three Months Ended March 31, 2017 2016 Apple 52.9 % 51.3 % Google 29.7 % 27.4 % At March 31, 2017, Apple Inc. (“Apple”) accounted for 56.7%, and Google Inc. (“Google”) accounted for 21.5% of total accounts receivable. At December 31, 2016, Apple accounted for 43.9%, Google accounted for 22.3%, Jirbo, Inc. (dba AdColony) accounted for 10.8%, and Fyber GmbH accounted for 10.5%, of total accounts receivable . No other customer or Digital Storefront represented more than 10% of the Company’s total accounts receivable as of these dates. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718 ): Improvements to Employee Share-Based Payment Accounting . The new guidance, which simplifies the accounting and presentation for share-based payments, provides for a number of amendments which impact the accounting for income taxes and the accounting for forfeitures. ASU 2016-09 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2016 and requires varied adoption methods for each respective amendment. The Company adopted this guidance in the first quarter of 2017 and elected to change its policy on accounting for forfeitures and recognize them as they occur using the modified retrospective transition method. This resulted in a cumulative-effect adjustment of $148 between opening accumulated deficit and additional paid in capital balance as of January 1, 2017. In addition, the other amendments related to accounting for income taxes and statutory tax withholding requirements were adopted using a prospective transition method and did not have a material impact on the Company’s consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-19, Technical Corrections and Improvements . The amendments in ASU No. 2016-19 represent changes to clarify the accounting standard codification, correct unintended application of guidance, or make minor improvements to the accounting standards codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. For public companies, the standard is effective immediately for amendments that do not have transition guidance. Amendments that are subject to transition guidance, the effective date is interim and annual reporting periods beginning after December 15, 2016. The Company adopted the standard immediately upon issuance for amendments that do not have transition guidance and effective January 1, 2017 for amendments that are subject to transition guidance. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , Simplifying the Test for Goodwill Impairment . This new accounting standard update simplifies the measurement of goodwill by eliminating the Step 2 impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The new guidance requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The new guidance becomes effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, though early adoption is permitted. The Company is currently assessing the impact of this new guidance . In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) , which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard will be effective in the first quarter of fiscal 2019. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. The standard will be effective in the first quarter of fiscal 2018 . Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements . In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . ASU No. 2016-16 requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU No. 2016-15 addresses eight specific cash flow issues with the objective of reducing existing diversity in practice. The guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases . The guidance requires lessees to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. The guidance is effective for annual and interim periods beginning after December 31, 2018. The updated standard mandates a modified retrospective transition method with early adoption permitted. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall - Recognition and Measurement of Financial Assets and Financial Liabilities . The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for a practicability exception. The updated standard is effective for interim and annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. Under the standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company does not plan to early adopt, and accordingly, will adopt the new standard effective January 1, 2018. The FASB recently issued several amendments to the standard, including clarifications on disclosure of prior-period performance obligations and remaining performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The Company has not yet selected a transition method. The Company is in initial stages of evaluation of the impact of the new standard on its accounting policies, processes, and system requirements. It has assigned internal resources in addition to the engagement of third party service providers to assist in the evaluation. While the Company is continuing to assess all potential impacts of this standard, it will continue to be considered the principal in its transactions and is the primary obligor to end-users for smartphone games distributed through Digital Storefronts and advertisements served through its advertising service providers. Therefore, revenue related to these arrangements will continue to be recognized on a gross basis, if the necessary information about the gross amounts or platform fees charged, before any adjustments, are made available to the Company by the Digital Storefronts and advertising service providers.

Business Combinations
Business Combinations	Note 3 — Business Combinations Crowdstar Inc. On November 2, 2016, the Company, acquired shares representing approximately 80.6% of the issued and outstanding voting power of Crowdstar Inc., a Delaware corporation (“Crowdstar”), from Time Warner Inc., Intel Capital Corporation and certain other stockholders of Crowdstar (the “Participating Stockholders”). Crowdstar is a developer of fashion and home decor genre games for mobile devices based in Burlingame, California. The Company acquired Crowdstar to leverage its casual games expertise, assembled workforce and existing mobile games in order to expand the Company’s game offerings on smartphones and tablets. The Company paid approximately $40,794 in cash to the Participating Holders in exchange for the acquired shares. In addition, certain drag-along provisions specified in a voting agreement by and among Crowdstar and certain other stockholders of Crowdstar were triggered. Pursuant to the drag-along provisions, certain other stockholders of Crowdstar were required to tender their Crowdstar capital stock to the Company on the same terms as the Participating Holders. Upon acquiring over 90% of the issued and outstanding voting power of Crowdstar pursuant to the drag-along provisions, on December 6, 2016, the Company acquired the remaining issued and outstanding shares of Crowdstar in a short-form merger under the laws of the State of Delaware for an additional $4,667 for a total of $45,461 for 100% ownership of Crowdstar. The allocation of the purchase price is based on valuations derived from estimated fair value assessments and assumptions used by the Company. While the Company believes that its estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different valuations assigned to the individual assets acquired and liabilities assumed, and the resulting amount of goodwill. The following table summarizes the preliminary fair values of assets acquired and liabilities assumed at the date of acquisition: Assets acquired: Cash and cash equivalents $ 4,492 Accounts receivable 3,905 Prepaid expenses 521 Other current assets 34 Fixed assets 315 Intangible assets: Titles, content and technology 16,000 Goodwill 28,776 Total assets 54,043 Liabilities assumed: Accounts payable (584) Accrued liabilities (4,284) Deferred revenue (1,500) Note payable - current portion (1,279) Long term liabilities (935) Total liabilities assumed (8,582) Net acquired assets $ 45,461 Acquisition-related intangibles included in the above table are finite-lived and are being amortized on a straight-line basis over their estimated lives of three to five years, which approximates the pattern in which the economic benefits of the intangible assets are expected to be realized. Of the total purchase price, $16,000 was allocated to identifiable intangible assets. Pursuant to ASC 805, the Company incurred and expensed a total of $1,582 in transitional costs associated with the acquisition of Crowdstar, which included $1,115 of research and development expense and $413 of general and administrative expense during the three months ended March 31, 2017. The Company allocated the residual value of $28,776 to goodwill. Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. In accordance with ASC 350, Intangibles – Goodwill and Other – Internal-Use Software , (“ASC 350”) , goodwill will not be amortized but will be tested for impairment at least annually. Goodwill created as a result of the Crowdstar acquisition is not deductible for tax purposes. Plain Vanilla Corp. On December 19, 2016, the Company acquired substantially all of the intangible assets and certain other assets of Plain Vanilla Corp. (“Plain Vanilla”), the developer of the QuizUp interactive software application for mobile devices, based in Reykjavik, Iceland. The Company acquired these assets in order to expand the Company’s game offerings on smartphones and tablets. The Company forgave and canceled $7.5 million in aggregate principal amount of convertible promissory notes of Plain Vanilla held by the Company, and all interest thereon, in exchange for acquiring the QuizUp assets and technology and other receivables. The deemed fair value of the consideration as of the acquisition date was determined to be $3,200. The acquired assets represent a business as defined in ASC 805, Business Combinations. The Company has integrated the acquired assets into the Company’s existing business. The asset purchase agreement also contains customary representations, warranties and covenants, including non-competition and indemnification provisions. The allocation of the purchase price is based on valuations derived from estimated fair value assessments and assumptions used by the Company. While the Company believes that its estimates and assumptions underlying the valuations are reasonable, different estimates and assumptions could result in different valuations assigned to the Fair value of purchase consideration: $ Assets acquired: Cash $ Accounts receivable Intangible assets: Title, content and technology Total assets acquired $ Acquisition-related intangibles included in the above table are finite-lived and are being amortized on a straight-line basis over their estimated lives of three years, which approximates the pattern in which the economic benefits of the intangible assets are expected to be realized. Of the total purchase price, $1,817 was allocated to identifiable intangible assets. No residual value was allocated to goodwill. Valuation Methodology The Company engaged a third party valuation firm to aid management in its analyses of the fair value of Crowdstar and the assets acquired from Plain Vanilla. All estimates, key assumptions and forecasts were either provided by or reviewed by the Company. While the Company chose to utilize a third party valuation firm, the fair value analyses and related valuations represent the conclusions of management and not the conclusions or statements of any third party. The Company valued titles, content, technology, and in-process research and development primarily using the Multi-Period Excess Earnings (“MPEE”) method of the income approach and key assumptions used included: projected revenue, cost of goods sold, and operating expenses for Crowdstar legacy titles, the future amortization tax benefit of the legacy titles, and a discount rate of between 20% and 35%. The fair value of Crowdstar’s deferred revenue was determined to be $1,500 as of the valuation date. This was valued using the estimated costs including hosting fees and salaries and benefits to support the contractual obligations associated with these revenue, plus a market participant margin. The deferred revenue will be recognized on a straight-line basis over nine months from the valuation date. As of the valuation date, Crowdstar was in process of developing a game, which was launched in the fourth quarter of 2016. Pro Forma Financial Information The results of operations for Crowdstar and Plain Vanilla and the estimated fair market values of the assets acquired and liabilities assumed have been included in the Company’s unaudited consolidated financial statements since their respective dates of acquisition. The unaudited pro forma financial information in the table below summarizes the combined results of the Company’s operations and those of Crowdstar and Plain Vanilla for the periods shown as if the acquisition of Crowdstar and Plain Vanilla had each occurred on January 1, 2015.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	Note 4 — Fair Value Measurements Fair Value Measurements The Company accounts for fair value in accordance with ASC 820, Fair Value Measurements and Disclosures (“ASC 820”). Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a three-tier hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of March 31, 2017, the Company’s financial assets and financial liabilities are presented below at fair value and were classified within the fair value hierarchy as follows (in thousands): Level 1 Level 2 Level 3 March 31, 2017 Financial Assets Cash and cash equivalents $ 73,150 $ — $ — $ 73,150 Restricted cash - long term and short term 1,164 — — 1,164 Total Financial Assets $ 74,314 $ — $ — $ 74,314 As of December 31, 2016, the Company’s financial assets and financial liabilities are presented below at fair value and were classified within the fair value hierarchy as follows (in thousands): Level 1 Level 2 Level 3 December 31, 2016 Financial Assets Cash and cash equivalents $ 102,102 $ — $ — $ 102,102 Restricted cash 1,312 — — 1,312 Total Financial Assets $ 103,414 $ — $ — $ 103,414 The Company’s cash and cash equivalents, which were held in operating bank accounts, are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. In addition, the Company’s restricted cash is classified within Level 1 of the fair value hierarchy. The carrying value of accounts receivable and payables approximates fair value due to the short time to expected payment or receipt of cash.

Goodwill and Intangible Assets	Note 6 — Goodwill and Intangible Assets Intangible Assets The Company’s intangible assets were acquired primarily in various acquisitions as well as in connection with the purchase of certain trademarks, brand assets and licensed content. The carrying amounts and accumulated amortization expense of the acquired intangible assets, including the impact of foreign currency exchange translation, at March 31, 2017 and December 31, 2016 were as follows: March 31, 2017 December 31, 2016 Gross Accumulated Net Gross Accumulated Net Carrying Amortization Carrying Carrying Amortization Carrying Value Expense Value Value Expense Value (Including (Including (Including (Including (Including (Including Estimated Impact of Impact of Impact of Impact of Impact of Impact of Useful Foreign Foreign Foreign Foreign Foreign Foreign Life Exchange) Exchange) Exchange) Exchange) Exchange) Exchange) Intangible assets amortized to cost of revenue: Titles, content and technology 3 - 5 yrs $ 40,946 $ (22,092) $ 18,854 $ 40,942 $ (19,255) $ 21,687 Carrier contract and related relationships 5 yrs 14,100 (11,748) 2,352 14,029 (11,427) 2,602 Licensed content 2.5 - 5 yrs 2,352 (2,352) — 2,334 (2,334) — Service provider license 9 yrs 214 (214) — 212 (212) — Trademarks 7 yrs 5,118 (3,690) 1,428 5,117 (3,510) 1,607 Total intangibles assets $ 62,730 $ (40,096) $ 22,634 $ 62,634 $ (36,738) $ 25,896 Acquisition-related intangibles included in the above table are finite-lived and are being amortized on a straight-line basis over their estimated lives, which approximate the pattern in which the economic benefits of the intangible assets are realized. The Company has included amortization of acquired intangible assets directly attributable to revenue-generating activities in cost of revenue. During the three months ended March 31, 2017 and 2016, the Company recorded amortization expense in the amounts of $3,262 and $2,324, respectively, in cost of revenue. As of March 31, 2017, total expected future amortization related to intangible assets was as follows: Amortization to Be Included in Cost of Year Ending December 31, Revenue 2017 $ 7,005 2018 5,905 2019 4,960 2020 3,258 2021 and thereafter 1,506 $ 22,634 Goodwill Goodwill for the periods indicated was as follows: March 31, 2017 December 31, 2016 Goodwill $ 189,943 $ 161,001 Accumulated impairment losses (73,111) (73,111) Balance as of January 1 116,832 87,890 Goodwill acquired during the year — 29,029 Effects of foreign currency exchange 10 (87) Balance as of period ended: 116,842 116,832 Goodwill 189,953 189,943 Accumulated impairment losses (73,111) (73,111) Balance as of period ended $ 116,842 $ 116,832 In accordance with ASC 350, the Company’s goodwill is not amortized but is tested for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable.

Investments	Note 7 — Investments In January 2016, the Company announced an investment of up to $7,500 in promissory notes convertible into a minority equity stake in Plain Vanilla. $5,000 was paid in January 2016 and the remaining $2,500 was paid in May 2016. As part of the investment, the Company also received a call option to acquire all outstanding equity of Plain Vanilla for 15 months from the closing of the initial investment, unless earlier terminated by the Company, at a pre-agreed price. Plain Vanilla is the Icelandic developer of the mobile game QuizUp, and is financed primarily through equity investments. On December 19, 2016, the Company acquired substantially all of the intangible assets and certain other assets of Plain Vanilla in exchange for forgiveness and cancellation of $7.5 million in aggregate principal amount of convertible promissory notes and all interest thereon. The call option agreement was terminated as of that date. See “Note 3 – Business Combinations” for additional details. The Company elected the fair value option to account for its investment in the promissory notes. The call option was recorded at cost. As of the investment date, the fair value of the promissory note and the call option was determined to be $2,600 and $2,400, respectively. As of March 31, 2016, the Company fair valued the promissory note at $2,900 and recorded a benefit of $300 in other income for the three months ended March 31, 2016. Plain Vanilla, prior to acquisition of its assets by the Company, was a variable interest entity (“VIE”). However, the Company determined that it was not the primary beneficiary of this VIE since the Company did not have the power to direct the activities of this VIE that most significantly impacted its economic performance. This determination was based on the following factors: (i) the development stage of Plain Vanilla’s products; (ii) the Company's inability to exercise control or decision making power over Plain Vanilla, as well as its lack of involvement in day-to-day operations and management decisions; and (iii) the fact that the call option to acquire Plain Vanilla, before the acquisition of its assets by the Company, was significantly out of the money. In January 2016, the Company acquired a minority equity stake and entered into a commercial agreement with Dairy Free Games, Inc. (“Dairy Free”). As part of the arrangement, the Company invested $2,000 in Dairy Free’s Series A preferred stock. The Company also agreed to provide up to $1,000 of recoupable and non-refundable development funding for a mobile game under development by Dairy Free. The development funding is payable in installments upon Dairy Free achieving certain milestones. Dairy Free is the developer of mobile video games and is financed primarily through equity investments. For Dairy Free, the preferred stock investment was recorded at cost. As of the investment date and as of March 31, 2017, the preferred stock investment was recorded at $2,000 in other long-term assets. The development funding was fully recognized as research and development expense as the development activities were performed. For the three months ended March 31, 2017 and March 31, 2016, the Company recorded $0 and $260 in research and development expense related to this arrangement, respectively. Dairy Free is a VIE; however, the Company has determined that it is not the primary beneficiary of this VIE since the Company currently does not have the power to direct the activities of this VIE that most significantly impact its economic performance. The Company made this determination based on the following factors: (i) the development stage of Dairy Free’s products; and (ii) the Company's inability to exercise control or decision making power over Dairy Free, based on the Company's ownership percentage and voting rights, as well as its lack of involvement in day-to-day operations and management decisions. The Company is not obligated to provide any explicit or implicit financial or other support to Dairy Free other than what was contractually agreed to in the investment agreement. The Company has no exposure to loss beyond its investments in Dairy Free. The Company evaluates its cost method investments for impairment on a quarterly basis. If the Company has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of a cost method investment, then the fair value of such cost method investment is not estimated.

Commitments and Contingencies
Commitments and Contingencies	Note 8 — Commitments and Contingencies Leases The Company leases office space under non-cancelable operating facility leases with various expiration dates through April 2021. Rent expense for the three months ended March 31, 2017 and 2016 was $1,171 and $1,241, respectively. The terms of the facility leases provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid. The deferred rent balance was $702 and $820 at March 31, 2017 and December 31, 2016, respectively, of which $ 456 and $619 was included within other long-term liabilities at March 31, 2017 and December 31, 2016, respectively. The Company has provided deposits for lines of credit totaling $ 1,054 to secure its obligations under the leases, which have been classified as restricted cash on the Company’s consolidated balance sheet as of March 31, 2017. As of March 31, 2017, future minimum lease payments under non-cancelable operating leases were as follows: Minimum Operating Lease Year Ending December 31, Payments 2017 (remaining 9 months) $ 3,109 2018 2,101 2019 1,671 2020 1,004 2021 and thereafter 114 $ 7,999 Minimum Guaranteed Royalties and Developer Commitments The Company has entered into license and publishing agreements with various celebrities, Hollywood studios, athletes, sports organizations, and other well-known brands and properties to develop and publish games for mobile devices. Pursuant to some of these agreements, the Company is required to make minimum guaranteed royalty payments regardless of r evenue generated by the applicable game, which may not be dependent on any deliverables . The significant majority of these minimum guaranteed royalty payments are recoupable against future royalty obligations that would otherwise become payable, or in certain circumstances, where not recoupable, are capitalized and amortized over the lesser of (1) the estimated life of the title incorporating licensed content or (2) the term of the license agreement. At March 31, 2017, future unpaid minimum guaranteed royalty commitments were as follows: Future Future Minimum Minimum Guarantee Developer Year Ending December 31, Commitments Commitments 2017 (remaining 9 months) $ 8,198 $ 2,650 2018 3,485 — 2019 4,250 — $ 15,933 $ 2,650 The amounts represented in the table above reflect the Company’s minimum cash obligations for the respective calendar years, but do not necessarily represent the periods in which they will be expensed in the Company’s consolidated financial statements. Future developer commitments as of March 31, 2017 were $2, 650 . These developer commitments reflect the Company’s minimum cash obligations to external software developers (“third-party developers”) to design and develop its software applications but do not necessarily represent the periods in which they will be expensed. The Company advances funds to these third-party developers, in installments, payable upon the completion of specified development milestones, and expenses third-party developer commitments as services are provided. Licensor commitments include $11,693 of commitments due to licensors that have been recorded in current and long-term liabilities and a corresponding amount in current and long-term assets because payment is not contingent upon performance by the licensor. The classification of commitments between long-term and short-term is determined based on the timing of recoupment of earned royalties calculated on projected revenue for the licensed intellectual property games. Indemnification Arrangements The Company has entered into agreements under which it indemnifies each of its officers and directors during his or her lifetime for certain events or occurrences while the officer or director is or was serving at the Company’s request in that capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits its exposure and enables the Company to recover a portion of any future amounts paid. Accordingly, the Company had recorded no liabilities for these agreements as of March 31, 2017 and December 31, 2016. In the ordinary course of its business, the Company includes standard indemnification provisions in most of its commercial agreements with Digital Storefronts and licensors. Pursuant to these provisions, the Company generally indemnifies these parties for losses suffered or incurred in connection with its games, including as a result of intellectual property infringement, viruses, worms and other malicious software, and legal or regulatory violations. The term of these indemnity provisions is generally perpetual after execution of the corresponding license agreement, and the maximum potential amount of future payments the Company could be required to make under these provisions is often unlimited. To date, the Company has not incurred costs to defend lawsuits or settle indemnified claims of these types. The Company had recorded no liabilities for these provisions as of March 31, 2017 and December 31, 2016. Contingencies From time to time, the Company is subject to various claims, complaints and legal actions in the normal course of business. The Company assesses its potential liability by analyzing specific litigation and regulatory matters using available information. The Company’s estimate of losses is developed in consultation with inside and outside counsel, which involves a subjective analysis of potential results and outcomes, assuming various combinations of appropriate litigation and settlement strategies. After taking all of the above factors into account, the Company determines whether an estimated loss from a contingency should be accrued by assessing whether a loss is deemed reasonably probable and the amount can be reasonably estimated. The Company further determines whether an estimated loss from a contingency should be disclosed by assessing whether a material loss is deemed reasonably possible. Such disclosure will include an estimate of the additional loss or range of loss or will state that an estimate cannot be made. The Company does not believe it is party to any currently pending litigation, the outcome of which is reasonably possible to have a material adverse effect on its operations, financial position or liquidity. However, the ultimate outcome of any litigation is uncertain and, regardless of outcome, litigation can have an adverse impact on the Company because of defense costs, potential negative publicity, diversion of management resources and other factors.

Stockholders' Equity
Stockholders' Equity	Note 9 — Stockholders’ Equity Warrants to Purchase Common Stock Celebrity Warrants During 2015, the Company issued warrants to celebrity licensors, and entities affiliated with one of the celebrity licensors, to purchase up to an aggregate of 1,100 shares of the Company’s common stock, subject to adjustments for dividends, reorganizations and other common stock events (collectively, the “Celebrity Warrants”). With respect to Celebrity Warrants covering 1,000 shares, such warrants vest with respect to 50% of the underlying shares upon public announcement of the related license agreement, with the remaining shares vesting in equal monthly installments over 24 months, subject to full acceleration in the event of (i) the Company’s full recoupment of the minimum guarantee payments under the related license agreement, (ii) the termination of the license agreement due to the Company’s material breach of the agreement or (iii) a change of control of the Company. With respect to the remaining Celebrity Warrants covering 100 shares issued in 2015, such warrants vest in equal monthly installments over 60 months, with up to 25% of the shares subject to accelerated vesting in the event the celebrity licensor approves game design documentation by a certain date and the related game commercially launches by a certain date. During the three months ended March 31, 2017, none of these vesting conditions were met. Each of the Celebrity Warrants may, at the election of the holder, be either exercised for cash or net exercised on a cashless basis. As of March 31, 2017, Celebrity Warrants covering 1, 600 shares of the Company’s common stock were outstanding. The fair value of the outstanding Celebrity Warrants is estimated using the Black-Scholes valuation model. The Black-Scholes valuation model requires inputs such as the expected term of the Celebrity Warrants, expected volatility and risk-free interest rate. Certain of these inputs are subjective and require significant analysis and judgment to develop. The Company will estimate and record the fair value of these Celebrity Warrants using a Black-Scholes valuation model when the above vesting conditions have been met. The amount recognized as expense with respect to these Celebrity Warrants was immaterial for the three months ended March 31, 2017 and 2016. MGM Warrants In July 2013, the Company and MGM Interactive Inc. (“MGM”) entered into a warrant agreement that provided MGM the right to purchase up to 3,333 shares of the Company’s common stock subject to adjustments for dividends, reorganizations and other common stock events (the “MGM Warrant”). As of March 31, 2017, MGM Warrants covering 2,667 shares of the Company’s common stock were outstanding. These remaining shares vest and become exercisable based on conditions related to the Company releasing mobile games based on mutually agreed upon intellectual property licensed by MGM to the Company. During each of the three months ended March 31, 2017 and 2016, none of these vesting conditions were met. Warrants outstanding at March 31, 2017 were as follows: Number Weighted of Shares Average Outstanding Exercise Average Under Price per Contractual Warrant Share Term Warrants outstanding, December 31, 2016 4,267 $ 3.61 4.78 Granted - - Exercised - - Warrants outstanding, March 31, 2017 4,267 $ 3.61 4.78

Stock Option and Other Benefit Plans
Stock Option and Other Benefit Plans	Note 10 — Stock Option and Other Benefit Plans 2007 Equity Incentive Plan In 2007, the Company’s Board of Directors adopted, and the Company’s stockholders approved, the 2007 Equity Incentive Plan (the “2007 Plan”). The 2007 Plan permits the Company to grant stock options, RSUs, and other stock-based awards to employees, non-employee directors and consultants. The 2007 Plan was amended and restated in 2013 (the “Amended 2007 Plan”) to, among other things, increase the aggregate number of shares of common stock authorized for issuance under the plan by 7,200 shares. In April 2015, the Company’s Board of Directors approved, and in June 2015, the Company’s stockholders approved, the Second Amended and Restated 2007 Equity Incentive Plan (the “Second Amended 2007 Plan”). The Second Amended 2007 Plan includes an increase of 13,000 shares in the aggregate number of shares of common stock authorized for issuance under the plan. It also includes a fungible share provision, pursuant to which each share that is subject to a stock-based award that is not a “full value award” (restricted stock, RSUs, or other stock-based awards where the price charged to the participant for the award is less than 100% of the fair market value) reduces the number of shares available for issuance by 1.32 shares (previously this fungible ratio was 1.39 shares under the Amended 2007 Plan). The Company may grant options under the 2007 Plan at prices no less than 85% of the estimated fair value of the shares on the date of grant as determined by its Board of Directors, provided, however, that (i) the exercise price of an incentive stock option (“ISO”) or non-qualified stock options (“NSO”) may not be less than 100% or 85%, respectively, of the estimated fair value of the underlying shares of common stock on the grant date, and (ii) the exercise price of an ISO or NSO granted to a 10% stockholder may not be less than 110% of the estimated fair value of the shares on the grant date. The fair value of the Company’s common stock is determined by the last sale price of such stock on the NASDAQ Global Market on the date of determination. The stock options granted to employees generally vest with respect to 25% of the underlying shares one year from the vesting commencement date and with respect to an additional 1/48 th of the underlying shares per month thereafter. Stock options granted before October 25, 2007 and after June 4, 2015 have a contractual term of ten years and stock options granted on or after October 25, 2007 and before June 4, 2015 have a contractual term of six years. As of March 31, 2017, 2, 669 shares were available for future grants under the Second Amended 2007 Plan. 2007 Employee Stock Purchase Plan In 2007, the Company’s Board of Directors adopted, and the Company’s stockholders approved, the 2007 Employee Stock Purchase Plan (the “2007 Purchase Plan”). As of March 31, 2017 , 735 shares were available for issuance under the 2007 Purchase Plan. 2008 Equity Inducement Plan In March 2008, the Company’s Board of Directors adopted the 2008 Equity Inducement Plan (the “Inducement Plan”) to augment the shares available under its existing 2007 Plan. The Company has not sought stockholder approval for the Inducement Plan. As such, awards under the Inducement Plan are granted in accordance with NASDAQ Listing Rule 5635(c)(4) and only to persons not previously an employee or director of the Company, or following a bona fide period of non-employment, as an inducement material to such individuals entering into employment with the Company. The Inducement Plan initially permitted the Company to grant only nonqualified stock options, but effective November 2013, the Compensation Committee of the Company’s Board amended the Inducement Plan to permit the award of RSUs under the plan. The Company may grant NSOs under the Inducement Plan at prices less than 100% of the fair value of the shares on the date of grant, at the discretion of its Board of Directors. The fair value of the Company’s common stock is determined by the last sale price of such stock on the NASDAQ Global Market on the date of determination. In December 2015, the Company’s Compensation Committee approved an increase in the number of authorized shares of common stock available for grant under the Inducement Plan by 1,000 shares in connection with grants made to Nick Earl upon his hiring as President of Global Studios. In November 2016, the Company’s Compensation Committee approved an increase of 6,000 shares in the aggregate number of shares of common stock authorized under the plan in connection with grants made to employees of Crowdstar following our acquisition of Crowdstar. As of March 31, 2017 , 1,227 shares of common stock were reserved for future grants under the Inducement Plan. Share-Based Awards Available for Grant The calculation of share-based awards available for grant under the Second Amended 2007 Plan and 2008 Equity Inducement Plan for the three months ended March 31, 2017 is as follows: Shares Available Balances at December 31, 2016 3,864 Increase in authorized shares — Share-based awards granted (1) (1,401) Share-based awards canceled (2) 1,433 Balances at March 31, 2017 3,896 (1) Under the terms of the Amended 2007 Plan, RSUs granted on or after June 6, 2013 but before June 4, 2015 reduced the number of shares available for grant by 1.39 shares for each share subject to an RSU award. Under the terms of the Second Amended 2007 Plan, RSUs granted on or after June 4, 2015 reduce the number of shares available for grant by 1.32 shares for each share subject to an RSU award. (2) Under the terms of the Amended 2007 Plan, RSUs forfeited and returned to the pool of shares available for grant that were granted on or after June 6, 2013 but before June 4, 2015 increase the pool by 1.39 shares for each share subject to an RSU that is forfeited. RSUs forfeited and returned to the pool of shares available for grant that were granted on or after June 4, 2015 increase the pool by 1.32 shares for each share subject to an RSU that is forfeited. RSU Activity A summary of the Company’s RSU activity for the three months ended March 31, 2017 is as follows: Weighted Number of Average Aggregate Units Grant Date Intrinsic Outstanding Fair Value Value Awarded and unvested, December 31, 2016 8,224 $ 3.33 Granted 394 $ 2.07 Vested (476) $ 4.06 Forfeited (462) $ 3.31 Awarded and unvested, March 31, 2017 7,680 $ 3.22 Restricted stock units vested and expected to vest at March 31, 2017 7,680 $ 3.22 $ 17,433 Stock Option Activity The following table summarizes the Company’s stock option activity for the three months ended March 31, 2017 : Options Outstanding Weighted Weighted Number Average Average Aggregate of Exercise Contractual Intrinsic Shares Price Term (Years) Value Balances at December 31, 2016 15,813 $ 2.74 $ — Options granted 881 $ 2.01 Options canceled (594) $ 3.39 Options exercised — $ — Balances at March 31, 2017 16,100 $ 2.67 7.18 $ 1,631 Options vested and expected to vest at March 31, 2017 16,100 $ 2.67 7.18 $ 1,631 Options exercisable at March 31, 2017 5,009 $ 3.58 2.54 $ — The aggregate intrinsic value in the preceding table is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of the Company’s common stock on The NASDAQ Global Market of $2.27 per share as of March 31, 2017 (the last trading day in the quarter). Consolidated net cash proceeds from option exercises were $0 and $100 for the three months ended March 31, 2017 and 2016, respectively. Stock-Based Compensation The cost of RSUs is determined using the fair value of the Company’s common stock based on the quoted closing price of the Company’s common stock on The NASDAQ Global Market on the date of grant. RSUs typically vest and are settled over approximately a four-year period with 25% of the shares vesting on or around the one-year anniversary of the grant date and the remaining shares vesting quarterly thereafter. Compensation cost is amortized on a straight-line basis over the requisite service period. Under ASC 718, Compensation-Stock Compensation (“ASC 718”), the Company estimated the fair value of each option award on the grant date using the Black-Scholes option valuation model and the weighted average assumptions noted in the following table. Three Months Ended March 31, 2017 2016 Dividend yield — % — % Risk-free interest rate 1.73 % 1.20 % Expected volatility 50.1 % 56.1 % Expected term (years) 4.00 4.00 The Company based its expected volatility on its own historical volatility and the historical volatility of a peer group of publicly traded entities. The expected term of options gave consideration to early exercises, post-vesting cancellations and the options’ contractual term ranging from six to ten years. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury Constant Maturity Rate as of the date of grant. The weighted-average fair value of stock options granted during the three months ended March 31, 2017 and 2016 was $0.81 and $4.09 per share, respectively. The following table summarizes the consolidated stock-based compensation expense by line items in the unaudited condensed consolidated statement of operations: Three Months Ended March 31, 2017 2016 Research and development $ 1,441 $ 1,194 Sales and marketing 362 292 General and administrative 1,738 2,059 Total stock-based compensation expense $ 3,541 $ 3,545 As of March 31, 2017 , the Company had $22,6 45 of total unrecognized compensation expense related to RSUs. As of March 31, 2017 , the Company had $9, 315 of total unrecognized compensation expense related to stock options. The unrecognized compensation expense related to RSUs will be recognized over a weighted average period of 2. 77 years. The unrecognized compensation expense related to stock options will be recognized over a weighted average period of 3. 42 years .

Income Taxes
Income Taxes	Note 11 — Income Taxes The Company recorded an income tax benefit of $12 and $166 for the three months ended March 31, 2017 and 2016 , respectively. The change in income tax provision was due to changes in pre-tax income in the United States and certain foreign entities. The income tax rates vary from the Federal and State statutory rates due to the valuation allowances on the Company’s net operating losses, foreign tax rate differences and withholding taxes. The Company computes its quarterly income tax provision by using a forecasted annual effective tax rate and adjusts for any discrete items arising during the quarter. The Company accounts for uncertain tax positions in accordance with ASC 740. As of March 31, 2017 and December 31, 2016, the total amount of unrecognized tax benefits was $11,524 and $11,011, respectively. As of March 31, 2017 and December 31, 2016, approximately $439 and $421, respectively, of unrecognized tax benefits, if recognized, would impact the Company’s effective tax rate. The remaining balance, if recognized, would adjust the Company’s deferred tax assets, each of which are subject to a valuation allowance. As of March 31, 2017 , the Company anticipated that the liability for uncertain tax positions, excluding interest and penalties, could decrease by approximately $82 within the next twelve months due to the expiration of certain statutes of limitation in foreign jurisdictions in which the Company does business. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits in income tax expense. The Company recorded an expense of $14 and $17 related to interest on uncertain tax positions during the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017 and December 31, 2016, the Company had a liability of $264 and $294, respectively, related to interest and penalties for uncertain tax positions. The Company is subject to taxation in the United States and various foreign jurisdictions. The material jurisdictions subject to examination by tax authorities are primarily the State of California, United States, Canada, China, and India. The Company’s federal tax returns are open by statute for tax years 1997 and forward and California tax returns are open by statute for tax years 2003 and forward and could be subject to examination by the tax authorities. The Company’s China income tax returns are open by statute for tax years 2011 and forward. The Company has not made a provision for income taxes on unremitted earnings of its foreign controlled subsidiaries, excluding China, as of March 31, 2017. However, if any such balances were to be repatriated, additional U.S. federal income tax payments could result. Computation of the potential deferred tax liabilities associated with unremitted earnings deemed to be indefinitely reinvested is not practicable.

Segment Reporting
Segment Reporting	Note 12 — Segment Reporting ASC 280, Segment Reporting (“ASC 280”), establishes standards for reporting information about operating segments. It defines operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company’s Chief Executive Officer, who is also chief operating decision maker, makes decisions and manages the Company’s operations as one operating segment . The financial information reviewed by him is included within one operating segment for purposes of allocating resources and evaluating financial performance. Accordingly, the Company reports as a single reportable segment—mobile games. In the case of Digital Storefronts, revenue are attributed to the geographic location where the end-user makes the purchase.

The Company, Basis of Presentation and Summary of Significant Accounting Policies
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on March 10, 2017. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, which the Company believes are necessary for a fair statement of the Company’s financial position as of March 31, 2017 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2017 and 2016, respectively. These unaudited condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year. The unaudited condensed consolidated balance sheet presented as of December 31, 2016 has been derived from the audited consolidated financial statements as of that date, and the unaudited condensed consolidated balance sheet presented as of March 31, 2017 has been derived from the unaudited condensed consolidated financial statements as of that date. Certain prior year balances have been reclassified to conform to the current year presentation. Such reclassifications did not affect revenue, operating loss, net loss, cash flows, total assets, total liabilities or stockholders’ equity. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable. The Company derives its accounts receivable from revenue earned from customers or through Digital Storefronts located in the United States and other locations outside of the United States. The Company performs ongoing credit evaluations of its customers’ and the Digital Storefronts’ financial condition and, generally, requires no collateral from its customers or the Digital Storefronts. The Company bases its allowance for doubtful accounts on management’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company reviews past due balances over a specified amount individually for collectability on a monthly basis. It reviews all other balances quarterly. The Company charges off accounts receivable balances against the allowance when it determines that the amount will not be recovered. The following table summarizes the revenue from customers or aggregate purchases through Digital Storefronts in excess of 10% of the Company’s revenue: Three Months Ended March 31, 2017 2016 Apple 52.9 % 51.3 % Google 29.7 % 27.4 % At March 31, 2017, Apple Inc. (“Apple”) accounted for 56.7%, and Google Inc. (“Google”) accounted for 21.5% of total accounts receivable. At December 31, 2016, Apple accounted for 43.9%, Google accounted for 22.3%, Jirbo, Inc. (dba AdColony) accounted for 10.8%, and Fyber GmbH accounted for 10.5%, of total accounts receivable . No other customer or Digital Storefront represented more than 10% of the Company’s total accounts receivable as of these dates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-09, Compensation - Stock Compensation (Topic 718 ): Improvements to Employee Share-Based Payment Accounting . The new guidance, which simplifies the accounting and presentation for share-based payments, provides for a number of amendments which impact the accounting for income taxes and the accounting for forfeitures. ASU 2016-09 is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2016 and requires varied adoption methods for each respective amendment. The Company adopted this guidance in the first quarter of 2017 and elected to change its policy on accounting for forfeitures and recognize them as they occur using the modified retrospective transition method. This resulted in a cumulative-effect adjustment of $148 between opening accumulated deficit and additional paid in capital balance as of January 1, 2017. In addition, the other amendments related to accounting for income taxes and statutory tax withholding requirements were adopted using a prospective transition method and did not have a material impact on the Company’s consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-19, Technical Corrections and Improvements . The amendments in ASU No. 2016-19 represent changes to clarify the accounting standard codification, correct unintended application of guidance, or make minor improvements to the accounting standards codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. For public companies, the standard is effective immediately for amendments that do not have transition guidance. Amendments that are subject to transition guidance, the effective date is interim and annual reporting periods beginning after December 15, 2016. The Company adopted the standard immediately upon issuance for amendments that do not have transition guidance and effective January 1, 2017 for amendments that are subject to transition guidance. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , Simplifying the Test for Goodwill Impairment . This new accounting standard update simplifies the measurement of goodwill by eliminating the Step 2 impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The new guidance requires an entity to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The new guidance becomes effective for goodwill impairment tests in fiscal years beginning after December 15, 2019, though early adoption is permitted. The Company is currently assessing the impact of this new guidance . In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) , which clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard will be effective in the first quarter of fiscal 2019. Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. The standard will be effective in the first quarter of fiscal 2018 . Early adoption is permitted. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements . In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . ASU No. 2016-16 requires that an entity recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU No. 2016-15 addresses eight specific cash flow issues with the objective of reducing existing diversity in practice. The guidance will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases . The guidance requires lessees to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. The guidance is effective for annual and interim periods beginning after December 31, 2018. The updated standard mandates a modified retrospective transition method with early adoption permitted. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall - Recognition and Measurement of Financial Assets and Financial Liabilities . The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income unless the investments qualify for a practicability exception. The updated standard is effective for interim and annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. Under the standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted for annual reporting periods beginning after December 15, 2016. The Company does not plan to early adopt, and accordingly, will adopt the new standard effective January 1, 2018. The FASB recently issued several amendments to the standard, including clarifications on disclosure of prior-period performance obligations and remaining performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). The Company has not yet selected a transition method. The Company is in initial stages of evaluation of the impact of the new standard on its accounting policies, processes, and system requirements. It has assigned internal resources in addition to the engagement of third party service providers to assist in the evaluation. While the Company is continuing to assess all potential impacts of this standard, it will continue to be considered the principal in its transactions and is the primary obligor to end-users for smartphone games distributed through Digital Storefronts and advertisements served through its advertising service providers. Therefore, revenue related to these arrangements will continue to be recognized on a gross basis, if the necessary information about the gross amounts or platform fees charged, before any adjustments, are made available to the Company by the Digital Storefronts and advertising service providers.
