The Company and Summary of Sign

The Company and Summary of Significant Accounting Policies	3 Months Ended

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 to appeal to a broad cross section of the 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, games based on celebrities and other well-known brands and properties. 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, 2015 filed with the SEC on March 4, 2016. 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, 2016 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2016 and 2015, 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, 2015 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, 2016 has been derived from the unaudited condensed consolidated financial statements as of that date. 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. Variable Interest Entities The Company has interests in other entities that are variable interest entities (“VIEs”). Determining whether to consolidate a VIE requires judgment in assessing (i) whether an entity is a VIE and (ii) if the Company is the entity’s primary beneficiary and thus required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company’s evaluation includes identification of significant activities and an assessment of its ability to direct those activities based on governance provisions and other applicable agreements and circumstances. The Company’s assessment of whether it is the primary beneficiary of its VIEs requires significant assumptions and judgment. 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 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 that accounted for more than 10% of the Company’s revenue for the periods indicated: Three Months Ended March 31, 2016 2015 Apple Google At March 31, 2016, Apple Inc. (“Apple”) accounted for 40.9%, Google Inc. (“Google”) accounted for 20.8 %, and Jirbo Inc. (dba AdColony) (“AdColony”) accounted for 20.6% of the Company’s total accounts receivable. At December 31, 2015, Apple accounted for 31.4% , AdColony accounted for 26.2% , and Google accounted for 19.2% 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”) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . ASU 2016-19 simplifies some aspects of the accounting for share-based payment award transactions, including: (a) income tax consequences, (b) classification of awards as either equity or liabilities, and (c) classification on the statement of cash flows. Early adoption is permitted. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers, which amends the principal-versus agent implementation guidance in the new revenue standard (ASU 2014-09), and clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. The updated standard will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is permitted. The updated standard will be effective for the Company beginning January 1, 2018. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases . The new 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 2016-01, “ Financial Instruments — Overall - Recognition and Measurement of Financial Assets and Financial Liabilities .” The new 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 November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes . The new guidance requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company early adopted this guidance on a prospective basis as of December 31, 2015. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. The new guidance requires that adjustments made to provisional amounts recognized in a business combination be recorded in the period such adjustments are determined, rather than retrospectively adjusting previously reported amounts. The new standard has been effective for fiscal years, and interim periods within those fiscal years, since December 15, 2015. The adoption of this standard did not have a material impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software . The standard amended the existing accounting standards for intangible assets and provides explicit guidance to customers in determining the accounting for fees paid in a cloud computing arrangement, wherein the arrangements that do not convey a software license to the customer are accounted for as service contracts. The pronouncement has been effective for reporting periods beginning after December 15, 2015. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis . ASU 2015-02 changes the guidance with respect to the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new standard has been effective for all annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosure. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method with early adoption permitted. The updated standard will be effective for the Company beginning January 1, 2018. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements.

Net Income/(Loss) Per Share
Net Income/(Loss) Per Share	Note 2 — Net Income/(Loss) Per Share The Company computes basic net income/(loss) per share by dividing its net income or loss for the period by the weighted average number of common shares outstanding during the period less the weighted average common shares subject to restrictions imposed by the Company. Diluted net income/(loss) per share reflects the potential dilution that could occur from shares of common stock issuable through stock-based compensation plans ( including stock options, restricted stock units (“RSUs”) and common stock issuable through the Company’s employee stock purchase plan), and warrants by application of the treasury stock method.

Fair Value Measurements
Fair Value Measurements	Note 3 — Fair Value Measurements Fair Value Measurements The Company accounts for fair value in accordance with Accounting Standards Codification (“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. The inputs to the valuation techniques used to measure fair value are classified into the following categories: 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, 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 March 31, 2016 Financial Assets Cash and cash equivalents — — Restricted cash — — Convertible promissory note investment in Plain Vanilla Corp. — — Call option to acquire Plain Vanilla Corp. (1) — — Total Financial Assets — (1) These assets are carried on the consolidated balance sheet on a historical cost basis (see “Note 6 - Investments") As of December 31, 2015, 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, 2015 Financial Assets Cash and cash equivalents — — Restricted cash — — Total Financial Assets — — 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. The Company engaged third party valuation experts to aid management in its analysis of the fair value of the promissory note issued to the Company, and the Company’s option to acquire all of the outstanding equity (“call option”) of, Plain Vanilla Corp (“Plain Vanilla”). See “Note 6 – Investments” below for further information on the promissory note and call option. The fair value of the promissory note was estimated using a probability weighted assessment of the expected cash flows discounted to their present value. The discount rate of 88.1% used in the analysis reflects the early stage nature of the entity and the overall gaming industry indices . The assumptions used in the expected cash flows model are level 3 inputs as defined above. The fair value of the call option was estimated using the probability weighted Black-Scholes valuation model. The Black-Scholes valuation model requires inputs such as the expected term of the call option, expected volatility and risk-free interest rate. Certain of these inputs are subjective and require significant analysis and judgment to develop. The weighted average assumptions used by the company are level 3 inputs as defined above and are noted in the following table: Three Months Ended March 31, 2016 Dividend yield — % Risk-free interest rate % Expected volatility % Expected term (in years) The following table presents the changes in fair value of the Plain Vanilla promissory note and the call option: Three months ended March 31, 2016 Asset at the Increase/ Asset at the beginning of (decrease) in end of the period (1) fair value the period Convertible promissory note investment in Plain Vanilla Corp.

The carrying amounts and accumulated amortization expense of the acquired intangible assets, including the impact of foreign currency exchange translation, at March 31, 2016 and December 31, 2015 were as follows: March 31, 2016 December 31, 2015 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 yrs $ $ $ $ $ $ Catalogs 1 yr — — ProvisionX Technology 6 yrs — — Carrier contract and related relationships 5 yrs Licensed content 2.5 - 5 yrs Service provider license 9 yrs Trademarks 7 yrs Other intangible assets amortized to operating expenses: Emux Technology 6 yrs — — Non-compete agreements 4 yrs — — — — Total intangibles assets $ $ $ $ $ $ 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 approximates 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 and amortization of acquired intangible assets not directly attributable to revenue-generating activities in operating expenses. During the three months ended March 31, 2016 and 2015, the Company recorded amortization expense in the amounts of $ 2,324 and $2,434 respectively, in cost of revenue. During the three months ended March 31, 2016 and 2015, the Company recorded amortization expense in the amounts of $ 0 and $127 , respectively, in operating expenses. As of March 31, 2016, total expected future amortization related to intangible assets was as follows: Amortization to Be Included in Cost of Year Ending December 31, Revenue 2016 $ 2017 2018 2019 2020 and thereafter — $ Goodwill Goodwill for the periods indicated was as follows: March 31, 2016 December 31, 2015 Total Total Goodwill $ $ Accumulated Impairment Losses Balance as of January 1 Goodwill Acquired during the year — — Effects of Foreign Currency Exchange Balance as of period ended: Goodwill Accumulated Impairment Losses Balance as of period ended $ $ 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. The Company performs its annual impairment review of its goodwill balance as of September 30 or more frequently if triggering events occur. The Company evaluates qualitative factors and overall financial performance to determine whether it is necessary to perform the first step of the multiple-step goodwill test. This step is referred to as “Step 0.” Step 0 involves, among other qualitative factors, weighing the relative impact of factors that are specific to the reporting unit as well as industry and macroeconomic factors. After assessing those various factors, if it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the entity will need to proceed to the first step of the goodwill impairment test. ASC 350 requires a multiple-step approach to testing goodwill for impairment for each reporting unit annually, or whenever events or changes in circumstances indicate the fair value of a reporting unit is below its carrying amount. The first step measures for impairment by applying the fair value-based tests at the reporting unit level. The second step (if necessary) measures the amount of impairment by applying the fair value-based tests to individual assets and liabilities within each reporting unit. The fair value of the reporting units is estimated using a combination of the market approach, which utilizes comparable companies’ data, and/or the income approach, which uses discounted cash flows.

Investments	Note 6 — 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, of which $5,000 was paid in January 2016 and the remaining $2,500 is payable upon Plain Vanilla achieving certain operational milestones during the term of the note purchase agreement pursuant to which the promissory notes were issued. 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. 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, including $350 of which was paid in January 2016 and the remaining $650 of which may become payable upon Dairy Free achieving certain milestones. Dairy Free is the developer of mobile video games and is financed primarily through equity investments. Plain Vanilla and Dairy Free are VIEs; however, the Company has determined that it is not the primary beneficiary of these VIEs since the Company currently does not have the power to direct the activities of the VIEs that most significantly impact their economic performance. The Company made this determination based on the following factors: (i) the development stage of the VIEs' products; (ii) the Company's inability to exercise control or decision making power over the VIEs, 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; and (iii) the fact that the call option to acquire Plain Vanilla is currently significantly out of the money. The Company has not accounted for these investments under ASC 323, Investments – Equity Method and Joint Ventures , as the convertible promissory note issued by Plain Vanilla and the preferred stock of Dairy Free have risk and rewards characteristics that are not substantially similar to the common stock of these entities. For Plain Vanilla, the Company has 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, and recorded in other long-term assets. 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 Dairy Free, the preferred stock investment was recorded at cost. As of the investment date and as of March 31, 2016, the preferred stock investment was recorded at $2,000 in other long-term assets. The development funding will be recognized as research and development expense as the development activities are performed. For the three months ended March 31, 2016, the Company recognized $260 in research and development expense related to this arrangement. The Company is not obligated to provide any explicit or implicit financial or other support to Plain Vanilla and Dairy Free other than what was contractually agreed to in the respective investment agreements. The Company has no exposure to loss beyond its investment in Plain Vanilla and Dairy Free.

Commitments and Contingencies
Commitments and Contingencies	Note 7 — Commitments and Contingencies Leases The Company leases office space under non-cancelable operating facility leases with various expiration dates through November 2020. Rent expense for the three months ended March 31, 2016 and 2015 was $ 1,241 and $1,002 , 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 $71 4 and $749 at March 31, 2016 and December 31, 2015, respectively, of which $605 and $692 was included within other long-term liabilities at March 31, 2016 and December 31, 2015, respectively. As of March 31, 2016, future minimum lease payments under non-cancelable operating leases were as follows: Minimum Operating Lease Year Ending December 31, Payments 2016 $ 2017 2018 2019 2020 and thereafter $ 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 (i) the estimated life of the title incorporating licensed content or (ii) the term of the license agreement. At March 31, 2016, future unpaid minimum guaranteed royalty commitments were as follows: Future Future Minimum Minimum Guarantee Developer Year Ending December 31, Commitments Commitments 2016 $ $ 2017 2018 — $ $ The amounts represented in the table above reflect our 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, 2016 were $1,150 . 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 $3 6,669 of commitments 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. Income Taxes As of March 31, 2016 , unrecognized tax benefits and potential interest and penalties are classified within “other long-term liabilities” and “accounts payable” on the Company’s unaudited condensed consolidated balance sheets. As of March 31, 2016 , the settlement of $609 of the Company’s income tax liabilities could not be determined; however, the liabilities are not expected to become due within the next 12 months. 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. On November 4, 2015, Just Games Interactive LLC (d/b/a Kung Fu Factory, f/k/a Tiny Fun Studios) (“Just Games”) filed a complaint in the U.S. District Court for the Central District of California against the Company, Kristen Jenner (f/k/a Kris Kardashian) and additional yet-to-be named defendants. The complaint alleged direct copyright infringement against the Company and direct and contributory copyright infringement and breach of implied contract against the other defendants. Just Games was seeking at least $10,000 in damages as well as other relief, including costs, permanent and temporary injunctive relief, an accounting of profits, a constructive trust and such other costs the Court deemed just and proper. The Company filed a motion to dismiss the complaint on January 27, 2016. On February 1, 2016, Just Games filed a voluntary motion to dismiss their case against the Company without prejudice. 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 8 — Stockholders’ Equity Tencent Investment On April 29, 2015, the Company entered into a purchase agreement with Tencent Holdings Limited (“Tencent”) and Tencent’s controlled affiliate, Red River Investment Limited (“Red River”). Pursuant to the Purchase Agreement, the Company issued to Red River in a private placement an aggregate of 21,000 shares of the Company’s common stock (the “Shares”) at a purchase price of $6.00 per share, for aggregate net proceeds of $125,15 6 , after offering expenses. The Company issued 12,500 of the Shares to Red River on April 29, 2015 and issued the remaining 8,500 Shares at a second closing on June 3, 2015. 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. 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. 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, 2016, Celebrity Warrants covering 1,600 shares of the Company’s common stock were outstanding. With respect to the Celebrity Warrants covering the 100 shares issued in 2015, during the three months ended March 31, 2016 and 2015, the Company recorded a warrant compensation charge of $9 and $92 , respectively, which was included within cost of revenue. With respect to the Celebrity Warrants covering the 1,000 shares issued in 2015, the Company recorded a prepaid expense of $62 and recorded $310 under other long-term assets, in each case as of March 31, 2016. No amounts were recorded for such Celebrity Warrants as of March 31, 2015. 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, 2016, 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, 2016, and 2015, none of these vesting conditions were met. The Company estimated the fair value of the Celebrity Warrants using the Black-Scholes valuation model and the weighted average assumptions noted in the following table: Three Months Ended March 31, 2016 2015 Dividend yield — % — % Risk-free interest rate % % Expected volatility % % Expected term (in years) Warrants outstanding at March 31, 2016 were as follows: Number Weighted of Shares Exercise Outstanding Price Average Under per Contractual Warrant Share Term Warrants outstanding, December 31, 2015 $ Granted - - Exercised - - Warrants outstanding, March 31, 2016 During the three months ended March 31, 2016 and 2015, warrant holders exercised warrants to purchase 0 and 7 shares of the Company’s common stock, respectively, and the Company received gross proceeds of $0 and $10 , respectively, in connection with these exercises. These exercised warrants were issued by the Company in 2010 in connection with a private placement transaction.

Stock Option and Other Benefit Plans
Stock Option and Other Benefit Plans	Note 9 — 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, 2016, 9, 806 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, 2016, 1,618 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. As of March 31, 2016, 52 6 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, 2016 is as follows: Shares Available Balances at December 31, 2015 Share-based awards granted (1) Share-based awards canceled (2) Balances at March 31, 2016 (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, 2016, is as follows: Weighted Number of Average Aggregate Units Grant Date Intrinsic Outstanding Fair Value Value Awarded and unvested, December 31, 2015 Granted Vested Forfeited Awarded and unvested, March 31, 2016 $ Restricted stock units vested and expected to vest, March 31, 2016 $ $ Stock Option Activity The following table summarizes the Company’s stock option activity for the three months ended March 31, 2016: Options Outstanding Weighted Weighted Number Average Average Aggregate of Exercise Contractual Intrinsic Shares Price Term (Years) Value Balances at December 31, 2015 $ Options granted Options canceled Options exercised Balances at March 31, 2016 $ $ Options vested and expected to vest at March 31, 2016 $ $ Options exercisable at March 31, 2016 $ $ 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 $ 2.82 per share as of March 31, 2016 (the last trading day in the quarter). Consolidated net cash proceeds from option exercises were $ 100 and $895 for the three months ended March 31, 2016 and 2015, respectively. The Company realized $0 of income tax benefit from stock option exercises during the three months ended March 31, 2016, and $0 income tax benefit from stock option exercises during the three months ended March 31, 2015. As required, the Company presents excess tax benefits from the exercise of stock options, if any, as financing cash flows rather than operating cash flows. 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 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 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, 2016 2015 Dividend yield —% —% Risk-free interest rate Expected volatility Expected term (years) 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, 2016 and 2015 was $4.09 and $4.38 per share, respectively. The Company calculated employee stock-based compensation expense recognized for the three months ended March 31, 2016 and 2015 based on awards ultimately expected to vest and reduced it for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. 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, 2016 2015 Research and development $ $ Sales and marketing General and administrative Total stock-based compensation expense $ $ As of March 31, 2016 , the Company had $24,344 of total unrecognized compensation expense related to RSUs, net of estimated forfeitures. As of March 31, 2016, the Company had $ 2,872 of total unrecognized compensation expense related to stock options, net of estimated forfeitures. The unrecognized compensation expense related to RSUs will be recognized over a weighted average period of 2.84 years. The unrecognized compensation expense related to stock options will be recognized over a weighted average period of 2.51 years .

Income Taxes
Income Taxes	Note 10 — Income Taxes The Company recorded an income tax benefit of $166 and an income tax expense of $1,104 for the three months ended March 31, 2016 and 2015, 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 estimates its annual effective tax rate at the end of each quarterly period and records the tax effect of certain discrete items, which are unusual or occur infrequently, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized and jurisdictions where a reliable estimate of ordinary income cannot be made are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections. The Company’s ability to use its net operating loss carryforwards and federal and state tax credit carryforwards to offset future taxable income and future taxes, respectively, may be subject to restrictions attributable to equity transactions that result in changes in ownership as defined by Internal Revenue Code Section 382. The Company accounts for uncertain tax positions in accordance with ASC 740. As of March 31, 2016 and December 31, 2015, the total amount of unrecognized tax benefits was $9,714 and $ 9,218 , respectively. As of March 31, 2016 and December 31, 2015, approximately $543 and $540 , 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, 2016, the Company anticipated that the liability for uncertain tax positions, excluding interest and penalties, could decrease by approximately $1 39 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 $ 17 and $20 related to interest on uncertain tax positions during the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016 and December 31, 2015, the Company had a liability of $395 and $375 , 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, United Kingdom, Canada, and China. 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 statute of limitations for the Company’s 2014 tax returns for the various entities in the United Kingdom is expected to be closed in 2016. The Company’s China income tax returns are open by statute for tax years 2010 and forward.

Segment Reporting
Segment Reporting	Note 11 — Segment Reporting ASC 280, Segment Reporting , 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 the chief operating decision maker, makes decisions and manages the Company’s operations as one reporting unit, rather than as three separate regional territories, which used to be considered as three reporting units. In prior years, the Company’s Chief Executive Officer reviewed selected financial information on a geographic basis; however this information 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”. For purposes of enterprise-wide disclosures, the Company attributes revenue to geographic areas based on the country in which the distributor’s, advertising service provider’s or carrier’s principal operations are located. In the case of Digital Storefronts, revenue is attributed to the geographic location where the end-user makes the purchase. The Company generates its revenue in the following geographic regions: Three Months Ended March 31, 2016 2015 United States $ $ Americas, excluding the United States EMEA APAC $ $ The Company attributes its long-lived assets, which primarily consist of property and equipment, to a country primarily based on the physical location of the assets.

Subsequent Events	Note 14 — Subsequent Events In April 2016, the Company announced a cost reduction plan that includes a reduction in force of approximately 85 employees and the termination or restructuring of certain leases and other contracts in the Company’s China and U.S. offices. In connection with these actions, the Company currently expects to record a restructuring charge of approximately $2,250 to $3,000 . The Company currently estimates that approximately $1,500 of such charges will be related to employee severance and benefits and approximately $750 to $1,500 will be related to lease, contract termination and other costs. The Company expects to recognize the severance and benefits charges during the second quarter of 2016 and the lease, contract termination and other costs during the second quarter of 2016 through the first quarter of 2017. The Company expects substantially all of the severance and benefit charges, and a majority of the lease, contract termination and other costs, to entail cash expenditures.

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, 2015 filed with the SEC on March 4, 2016. 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, 2016 and its unaudited condensed consolidated results of operations for the three months ended March 31, 2016 and 2015, 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, 2015 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, 2016 has been derived from the unaudited condensed consolidated financial statements as of that date. 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.
Variable Interest Entities	Variable Interest Entities The Company has interests in other entities that are variable interest entities (“VIEs”). Determining whether to consolidate a VIE requires judgment in assessing (i) whether an entity is a VIE and (ii) if the Company is the entity’s primary beneficiary and thus required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company’s evaluation includes identification of significant activities and an assessment of its ability to direct those activities based on governance provisions and other applicable agreements and circumstances. The Company’s assessment of whether it is the primary beneficiary of its VIEs requires significant assumptions and judgment.
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 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 that accounted for more than 10% of the Company’s revenue for the periods indicated: Three Months Ended March 31, 2016 2015 Apple Google At March 31, 2016, Apple Inc. (“Apple”) accounted for 40.9%, Google Inc. (“Google”) accounted for 20.8 %, and Jirbo Inc. (dba AdColony) (“AdColony”) accounted for 20.6% of the Company’s total accounts receivable. At December 31, 2015, Apple accounted for 31.4% , AdColony accounted for 26.2% , and Google accounted for 19.2% 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”) 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting . ASU 2016-19 simplifies some aspects of the accounting for share-based payment award transactions, including: (a) income tax consequences, (b) classification of awards as either equity or liabilities, and (c) classification on the statement of cash flows. Early adoption is permitted. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers, which amends the principal-versus agent implementation guidance in the new revenue standard (ASU 2014-09), and clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. The updated standard will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is permitted. The updated standard will be effective for the Company beginning January 1, 2018. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases . The new 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 2016-01, “ Financial Instruments — Overall - Recognition and Measurement of Financial Assets and Financial Liabilities .” The new 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 November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes . The new guidance requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The Company early adopted this guidance on a prospective basis as of December 31, 2015. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. The new guidance requires that adjustments made to provisional amounts recognized in a business combination be recorded in the period such adjustments are determined, rather than retrospectively adjusting previously reported amounts. The new standard has been effective for fiscal years, and interim periods within those fiscal years, since December 15, 2015. The adoption of this standard did not have a material impact on the Company’s financial statements. In April 2015, the FASB issued ASU 2015-05, Intangibles-Goodwill and Other-Internal-Use Software . The standard amended the existing accounting standards for intangible assets and provides explicit guidance to customers in determining the accounting for fees paid in a cloud computing arrangement, wherein the arrangements that do not convey a software license to the customer are accounted for as service contracts. The pronouncement has been effective for reporting periods beginning after December 15, 2015. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis . ASU 2015-02 changes the guidance with respect to the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The new standard has been effective for all annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosure. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method with early adoption permitted. The updated standard will be effective for the Company beginning January 1, 2018. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements.
