| Organization and Principal Activities |
Momo Inc. (the “Company”) is the holding company for a group of companies, which is incorporated in the British Virgin Islands (“BVI”) on November 23, 2011. In July 2014, the Company was redomiciled in the Cayman Islands (“Cayman”) as an exempted company registered under the laws of the Cayman Islands, and was renamed Momo Inc. The Company, its subsidiaries, which include the wholly-foreign owned enterprises (“WFOEs”), its consolidated variable interest entities (“VIEs”) and VIEs’ subsidiaries (collectively the “Group”) are principally engaged in providing mobile-based social and entertainment services. The Group started its operation in July 2011. The Group started its monetization in the third quarter of 2013, by offering a platform for live video services, value-added services, mobile marketing services, mobile games and other services. In May 2018, the Company completed the acquisition of 100% equity stake of Tantan Limited (“Tantan”). Tantan is a leading social and dating app for the younger generation that was founded in 2014. Tantan is designed to help its users find and establish romantic connections as well as meet interesting people. The total consideration consisted of cash consideration of RMB 3,930,246 (US$613,181) and 5,328,853 Class A ordinary shares of the Company. Refer to Note 3 for further details. As of December 31, 2018, details of the Company’s major subsidiaries, VIEs and VIEs’ subsidiaries are as follows:
The VIE arrangements The People’s Republic of China (“PRC”) regulations currently limit direct foreign ownership of business entities providing value-added telecommunications services, advertising services and internet services in the PRC where certain licenses are required for the provision of such services. The Group provides substantially all of its services in China through certain PRC domestic companies, which hold the operating licenses and approvals to enable the Group to provide such mobile internet content services in the PRC. Specifically, these PRC domestic companies that are material to the Company’s business are Beijing Momo, Chengdu Momo, Tianjin Heer, Loudi Momo, QOOL Tianjin and Tantan Culture. The equity interests of these PRC domestic companies are held by PRC citizens or by PRC entities owned and/or controlled by PRC citizens. The Company obtained control over its VIEs by entering into a series of contractual arrangements with the VIEs and their equity holders (the “Nominee Shareholders”), which enable the Company to (1) have power to direct the activities that most significantly affects the economic performance of the VIEs, and (2) receive the economic benefits of the VIEs that could be significant to the VIEs. Accordingly, the Company is considered the primary beneficiary of VIEs and has consolidated the VIEs’ financial results of operations, assets and liabilities in the Company’s consolidated financial statements. In making the conclusion that the Company is the primary beneficiary of the VIEs, the Company’s rights under the Power of Attorney also provide the Company’s abilities to direct the activities that most significantly impact the VIEs economic performance. The Company also believes that this ability to exercise control ensures that the VIEs will continue to execute and renew the Exclusive Cooperation Agreements and pay service fees to the Company. By charging service fees in whatever amounts the Company deems fit, and by ensuring that the Exclusive Cooperation Agreements is executed and renewed indefinitely, the Company has the rights to receive substantially all of the economic benefits from the VIEs. Details of the typical structure of the Company’s significant VIEs are set forth below: Agreements that provide the Company effective control over the VIEs:
Pursuant to the Power of Attorney, the Nominee Shareholders of the VIEs each irrevocably appointed respective WFOEs as the attorney-in-fact to act on their behalf on all matters pertaining to the VIEs and to exercise all of their rights as a shareholder of the VIEs, including but not limited to convene, attend and vote on their behalf at shareholders’ meetings, designate and appoint directors and senior management members. The WFOEs may authorize or assign their rights under this appointment to a person as approved by its board of directors at its sole discretion. Each power of attorney will remain in force until the shareholder ceases to hold any equity interest in the VIEs. The Company believes the Powers of Attorney can demonstrate the power of its WFOEs to direct how the VIEs should conduct their daily operations.
Under the Exclusive Call Option Agreement among the WFOEs, the VIEs and their Nominee Shareholders, each of the Nominee Shareholders irrevocably granted the respective WFOE or its designated representative(s) an exclusive option to purchase, to the extent permitted under PRC law, all or part of his, her or its equity interests in the VIEs at the consideration equal to the nominal price or at lowest price as permitted by PRC laws. The WFOEs or their designated representative(s) have sole discretion as to when to exercise such options, either in part or in full. Without the WFOEs’ written consent, the Nominee Shareholders of the VIEs shall not transfer, donate, pledge, or otherwise dispose any equity interests of the VIEs in any way. In addition, any consideration paid by the WFOEs to the Nominee Shareholders of the VIEs in exercising the option shall be transferred back to the respective WFOE or its designated representative(s). This agreement could be terminated when all the shareholders’ equity were acquired by the WFOEs or their designated representative(s) subject to the law of People’s Republic of China. In addition, the VIEs irrevocably granted the WFOEs an exclusive and irrevocable option to purchase any or all of the assets owned by the VIEs at the lowest price permitted under PRC law. Without the WFOEs’ prior written consent, the VIEs and their Nominee Shareholders will not sell, transfer, mortgage or otherwise dispose of the VIEs’ material assets, legal or beneficial interests or revenues of more than certain amount or allow an encumbrance on any interest in the VIEs.
Each spouse of the married Nominee Shareholders of the VIEs entered into a Spousal Consent Letter, which unconditionally and irrevocably agreed that the equity interests in the VIEs held by and registered in the name of their spouse will be disposed of pursuant to the Equity Interest Pledge Agreement, the Exclusive Call Option Agreement, and the Power of Attorney. Each spouse agreed not to assert any rights over the equity interests in the VIEs held by their spouse. In addition, in the event that the spouse obtains any equity interests in the VIEs held by their spouse for any reason, they agreed to be bound by the contractual arrangements. Agreements that transfer economic benefits to the Company:
Each relevant VIEs has entered into an exclusive technology services agreement or an exclusive services agreement with the respective WFOEs, pursuant to which the relevant WFOEs provides exclusive services to the VIEs. In exchange, the VIEs pay a service fee to the WFOEs, the amount of which shall be determined, to the extent permitted by applicable PRC laws as proposed by the WFOEs, resulting in a transfer of substantially all of the profits from the VIEs to the WFOEs.
Under the equity interest pledge agreement among the WFOEs and each of the Nominee Shareholders of the VIEs, the Nominee Shareholders pledged all of their equity interests in the VIEs to the respective WFOEs to guarantee the VIEs’ and their shareholders’ payment obligations arising from the Exclusive Cooperation Agreements, Business Operation Agreement and the Exclusive Call Option Agreement, including but not limited to, the payments due to the respective WFOEs for services provided. If any VIEs or any of their Nominee Shareholders breaches their contractual obligations under the above agreements, the respective WFOEs, as the pledgee, will be entitled to certain rights and entitlements, including receiving priority proceeds from the auction or sale of whole or part of the pledged equity interests of the VIEs in accordance with PRC legal procedures. During the term of the pledge, the shareholders of the VIEs shall cause the VIEs not to distribute any dividends and if they receive any dividends generated by the pledged equity interests, they shall transfer such received amounts to an account designated by the respective parties according to the instruction of the respective WFOEs. The pledge will remain binding until the VIEs and their Nominee Shareholders have fully performed all their obligations under the Exclusive Cooperation Agreements, Business Operations Agreement and Exclusive Call Option Agreement.
Under the Business Operations Agreement among the WFOEs, the VIEs and the Nominee Shareholders of the VIEs, without the prior written consent of the WFOEs or their designated representative(s), the VIEs shall not conduct any transaction that may substantially affect the assets, business, operation or interest of the WFOEs. The VIEs and Nominee Shareholders shall also follow the WFOEs’ instructions on management of the VIEs’ daily operation, finance and employee matters and appoint the nominee(s) designated by the WFOEs as the director(s) and senior management members of the VIEs. In the event that any agreements between the WFOEs and the VIEs terminates, the WFOEs have the sole discretion to determine whether to continue any other agreements with the VIEs. The WFOEs are entitled to any dividends or other interests declared by the VIEs and the shareholders of the VIEs have agreed to promptly transfer such dividends or other interests to the WFOEs. The agreement shall remain effective for 10 years. At the discretion of the WFOEs, this agreement will be renewed on applicable expiration dates, or the WFOEs and the VIEs will enter into another exclusive agreement. Through these contractual agreements, the Company has the ability to effectively control the VIEs and is also able to receive substantially all the economic benefits of the VIEs. Risk in relation to the VIE structure The Company believes that the WFOEs’ contractual arrangements with the VIEs are in compliance with PRC law and are legally enforceable. The shareholders of the VIEs are also shareholders of the Company and therefore have no current interest in seeking to act contrary to the contractual arrangements. However, uncertainties in the PRC legal system could limit the Company’s ability to enforce these contractual arrangements and if the shareholders of the VIEs were to reduce their interest in the Company, their interests may diverge from that of the Company and that may potentially increase the risk that they would seek to act contrary to the contractual terms, for example by influencing the VIEs not to pay the service fees when required to do so. However, the Company cannot assure that when conflicts of interest arise, the shareholders will act in the best interests of the Company or that conflicts of interests will be resolved in the Company’s favor. Currently, the Company does not have existing arrangements to address potential conflicts of interest the shareholders of the VIEs may encounter in their capacity as the beneficial owners and director of the VIEs on the one hand, and as beneficial owners and directors or officer of the Company, on the other hand. The Company believes the shareholders of the VIEs will not act contrary to any of the contractual arrangements and the Exclusive Call Option Agreement provides the Company with a mechanism to remove the shareholders as the beneficial shareholders of the VIEs should they act to the detriment of the Company. The Company relies on the VIEs’ shareholders, as directors and officer of the Company, to fulfill their fiduciary duties and abide by laws of the PRC and the Cayman and act in the best interest of the Company. If the Company cannot resolve any conflicts of interest or disputes between the Company and the VIEs’ shareholders, the Company would have to rely on legal proceedings, which could result in disruption of its business, and there is substantial uncertainty as to the outcome of any such legal proceedings. The Company’s ability to control the VIEs also depends on the Power of Attorney. The WFOEs and VIEs have to vote on all matters requiring shareholder approval in the VIEs. As noted above, the Company believes this power of attorney is legally enforceable but may not be as effective as direct equity ownership. In addition, if the legal structure and contractual arrangements were found to be in violation of any existing PRC laws and regulations, the PRC government could:
The imposition of any of these penalties may result in a material and adverse effect on the Group’s ability to conduct the Group’s business. In addition, if the imposition of any of these penalties causes the Group to lose the rights to direct the activities of the VIEs or the right to receive their economic benefits, the Group would no longer be able to consolidate the VIEs. The Group does not believe that any penalties imposed or actions taken by the PRC government would result in the liquidation of the Company, WFOEs, or the VIEs. The following consolidated financial statements amounts and balances of the VIEs were included in the accompanying consolidated financial statements after the elimination of intercompany balances and transactions as of and for the years ended December 31:
The unrecognized revenue-producing assets that are held by the VIEs are primarily self-developed intangible assets such as domain names, trademark and various licenses which are un-recognized at the consolidated balance sheets.
The VIEs contributed an aggregate of 100% of the consolidated net revenues for each of the years ended December 31, 2016, 2017 and 2018, respectively. As of the fiscal years ended December 31, 2017 and 2018, the VIEs accounted for an aggregate of 18.4% and 17.7%, respectively, of the consolidated total assets, and 62.1% and 18.4%, respectively, of the consolidated total liabilities. The assets that were not associated with the VIEs primarily consist of cash and cash equivalents, term deposits, intangible assets and goodwill. There are no consolidated VIEs’ assets that are collateral for the VIEs’ obligations and can only be used to settle the VIEs’ obligations. There are no creditors (or beneficial interest holders) of the VIEs that have recourse to the general credit of the Company or any of its consolidated subsidiaries. There are no terms in any arrangements, considering both explicit arrangements and implicit variable interests that require the Company or its subsidiaries to provide financial support to the VIEs. However, if the VIEs ever need financial support, the Company or its subsidiaries may, at its option and subject to statutory limits and restrictions, provide financial support to its VIEs through loans to the shareholders of the VIEs or entrustment loans to the VIEs. Relevant PRC laws and regulations restrict the VIEs from transferring a portion of their net assets, equivalent to the balance of their statutory reserve and their share capital, to the Company in the form of loans and advances or cash dividends. Please refer to Note 20 for disclosure of restricted net assets. The Group may lose the ability to use and enjoy assets held by the VIEs that are important to the operation of business if the VIEs declare bankruptcy or become subject to a dissolution or liquidation proceeding. |

Basis of presentation The consolidated financial statements of the Group have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”). Basis of consolidation The consolidated financial statements of the Group include the financial statements of Momo Inc., its subsidiaries, its VIEs and VIEs’ subsidiaries. All inter-company transactions and balances have been eliminated upon consolidation. Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues, cost and expenses in the financial statements and accompanying notes. Significant accounting estimates reflected in the Group’s consolidated financial statements include revenue recognition, the acquisition’s purchase price allocation, the useful lives and impairment of property and equipment and intangible assets, the impairment of goodwill, the valuation allowance for deferred tax assets, and share-based compensation. Cash and cash equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments, which are unrestricted from withdrawal or use, or which have original maturities of three months or less when purchased. Term deposits Term deposits consist of bank deposits with an original maturity of over three months. Accounts receivable Accounts receivable primarily represents the cash due from third-party application stores and other payment channels and advertising customers, net of allowance for doubtful accounts. The Group makes estimates for the allowance for doubtful accounts based upon its assessment of various factors, including the age of accounts receivable balances, credit quality of third-party application stores and other payment channels, advertising customers and other customers, current economic conditions and other factors that may affect their ability to pay. An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable. Financial instruments Financial instruments of the Group primarily consist of cash and cash equivalents, term deposits, accounts receivable, equity securities without readily determinable fair value, accounts payable, deferred revenue, income tax payable, amount due from related parties and amount due to related parties. Cash and cash equivalents are recorded at fair value based on the quoted market price in an active market. The carrying values of term deposits, accounts receivable, accounts payable, deferred revenue, income tax payable, amount due from related parties and amount due to related parties approximate their fair values due to short-term maturities. It is not practical to estimate the fair value of the Group’s equity securities without readily determinable fair value because of the lack of quoted market price and the inability to estimate fair value without incurring excessive costs. Foreign currency risk The Renminbi (“RMB”) is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into foreign currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. Cash and cash equivalents of the Group included aggregate amounts of RMB4,116 million and RMB2,008 million as of December 31, 2017 and 2018, respectively, which were denominated in RMB. Concentration of credit risk Financial instruments that potentially expose the Group to concentration of credit risk consist primarily of cash and cash equivalents, term deposits and accounts receivable. The Group places their cash with financial institutions with high-credit ratings and quality. Third-party application stores and other payment channels accounting for 10% or more of accounts receivables are as follows:
Users or customers accounting for 10% or more of accounts receivables is as follows:
Concentration of revenue No user or customer accounted for 10% or more of net revenues for the years ended December 31, 2016, 2017 and 2018, respectively. Business combinations Business combinations are recorded using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805 “Business Combinations”. The cost of an acquisition is measured as the aggregate of the acquisition date fair value of the assets transferred to the sellers and liabilities incurred by the Company and equity instruments issued. Identifiable assets and liabilities acquired or assumed are measured separately at their fair values as of the acquisition date, irrespective of the extent of any noncontrolling interests. The purchase price of business acquisition is allocated to the tangible assets, liabilities, identifiable intangible assets acquired and non-controlling interest, if any, based on their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred. The Company adopted Accounting Standard Update (“ASU”) 2017-01 “Business Combination (Topic 805): Clarifying the Definition of a Business” on January 1, 2018 and applied the new definition of a business prospectively for acquisitions made subsequent to December 31, 2017. Upon the adoption of ASU 2017-01, a new screen test is introduced to evaluate whether a transaction should be accounted for as an acquisition and/or disposal of a business versus assets. In order for a purchase to be considered an acquisition of a business, and receive business combination accounting treatment, the set of transferred assets and activities must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the set of transferred assets and activities is not a business. The adoption of this standard requires future purchases to be evaluated under the new framework.
Equity securities without readily determinable fair value The Company adopted ASC Topic 321, Investments—Equity Securities (“ASC 321”) on January 1, 2018. Prior to 2018, the Company carried at cost its investments in investees that do not have readily determinable fair value and over which the Company does not have significant influence, in accordance with ASC Subtopic 325-20, Investments-Other: Cost Method Investments. Management regularly evaluates the impairment of the cost method investments based on the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of the investment. Subsequent to the Company’s adoption of ASC 321 for equity securities without readily determinable fair value that do not qualify for the existing practical expedient available in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), the Company elected to use the measurement alternative to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. Pursuant to ASC 321, for those equity securities that the Company elects to use the measurement alternative, the Company makes a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, the Company has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the Company recognizes an impairment loss in net income equal to the difference between the carrying value and fair value. Equity method investments The investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee between 20% and 50%. Other factors, such as representation in the investee’s Board of Directors, voting rights and the impact of commercial arrangements, are also considered in determining whether the equity method of accounting is appropriate. For the investment in limited partnerships, where the Group holds less than a 20% equity or voting interest, the Group’s influence over the partnership operating and financial policies is determined to be more than minor. Accordingly, the Group accounts for these investments as equity method investments. Under the equity method of accounting, the affiliated company’s accounts are not reflected within the Group’s consolidated balance sheets and statements of operations; however, the Group’s share of the earnings or losses of the affiliated company is reflected in the caption “share of income on equity method investments” in the consolidated statements of operations. An impairment change is recorded if the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than-temporary. The Group estimates the fair value of the investee company based on comparable quoted price for similar investment in active market, if applicable, or discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital. Available-for-sale investments For investments in investees’ stocks which are determined to be debt securities, the Group accounts for them as long-term available-for-sale investments when they are not classified as either trading or held-to-maturityinvestments. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Realized gains and losses and provision for decline in value judged to be other than temporary, if any, are recognized in the consolidated statements of operations.
The Group continually reviews its available-for-sale investments to determine whether a decline in fair value below the carrying value is other than temporary. The primary factors the Group considers in its determination are the length of time that the fair value of the investment is below the Group’s carrying value; the financial condition, operating performance and the prospects of the available-for-sale investee; and other specific information such as recent financing rounds. If the decline in fair value is deemed to be other than temporary, the carrying value of the available-for-sale investee is written down to fair value. The Group estimated the fair value of these investee companies based on discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital. Property and equipment, net Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated on a straight-line basis over the following estimated useful lives:
Intangible assets Intangible assets acquired through business acquisitions are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion. Purchased intangible assets and intangible assets arising from acquisitions are recognized and measured at fair value upon acquisition. Separately identifiable intangible assets that have determinable lives continue to be amortized over their estimated useful lives using the straight-line method as follows:
Impairment of long-lived assets with finite lives The Group reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Group measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the fair value of the assets.
Goodwill Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed of the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries. Goodwill is not amortized but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Company has an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. Based on the qualitative assessment, if it is more likely than not that the fair value of each reporting unit is less than the carrying amount, the quantitative impairment test is performed. In performing the two-step quantitative impairment test, the first step compares the fair values of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for the purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets, liabilities and goodwill to reporting units, and determining the fair value of each reporting unit. Convertible senior notes The Group determines the appropriate accounting treatment of its convertible senior notes in accordance with the terms in relation to the conversion feature, call and put options, and beneficial conversion feature. After considering the impact of such features, the Group may account for such instrument as a liability in its entirety, or separate the instrument into debt and equity components following the respective guidance described under ASC 815 “Derivatives and Hedging” and ASC 470 “Debt”. The debt discount, if any, together with the related issuance cost are subsequently amortized as interest expense, using the effective interest method, from the issuance date to the earliest maturity date. Interest expenses are recognized in the consolidated statement of operation in the period in which they are incurred. Fair value Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement as follows: Level 1 Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.
Level 3 Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. Revenue recognition Adoption of ASC, “Revenue from Contracts with Customers” In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606”) as modified by subsequently issued ASUs 2015-14, 2016-08,2016-10, 2016-12 and 2016-20 (collectively “ASU 2014-09”). On January 1, 2018, the Group adopted Topic 606 by applying the modified retrospective method to contracts that were not completed as of January 1, 2018. Results for the reporting periods beginning after January 1, 2018 are presented under Topic 606 while prior period amounts are not adjusted and continue to be reporting in accordance with the Group’s historical accounting under Topic 605. The adoption of Topic 606 did not have a material impact on the Group’s consolidated results of operations, financial position or cash flows but resulted in additional disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Group principally derives its revenue from live video services, value-added services, mobile marketing services, mobile games and other services. The Group recognizes revenue when control of the promised goods or services are transferred to the customers, in an amount that reflects the consideration that the Group expects to receive in exchange for those goods or services. The Group applied the five steps method outlined in Topic 606 to all revenue streams. In addition, the standard requires disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. For the years ended December 31, 2016, 2017 and 2018, all the revenue for the periods was recognized from contracts with customers. The Group’s revenue is reported net of discounts, value added tax and surcharges. The following table provides information about disaggregated revenue by types, including a reconciliation of the disaggregated revenue with the Group’s reportable segments:
The Group is principally engaged in providing live video services whereby users can enjoy live performances and interact with the broadcasters for free during the performance. Broadcasters can either host the performance on their own or join a talent agency. The Group generates revenue from sales of virtual items to its customers. The Group designs, creates and offers various virtual items for sales to users with pre-determined stand-alone selling price, which if users chose to, can be purchased and be presented to the broadcasters to show their support during their live video performance. The Group has a recharge system for users to purchase the Group’s virtual currency that can then be used to purchase virtual items on the Group’s platform. Users can recharge via various third-party application stores and other payment channels. Virtual currency is non-refundable and does not have any expiration date. Based on the turnover history of virtual currency, the Group determined that the virtual currency is often consumed soon after it is purchased and accordingly, the Group concluded that any breakage would be insignificant. Unconsumed virtual currency is recorded as deferred revenue. Virtual currencies used to purchase virtual items are recognized as revenue according to the prescribed revenue recognition policies of virtual items addressed below unless otherwise stated. All virtual items are non-refundable, consumed at a point-in-time and expire in a few days after the purchase. Under arrangements entered into with broadcasters and talent agencies, the Group shares a portion of the revenues derived from the sales of virtual items with them (“Revenue Sharing”). The Group has evaluated and determined that it is the principal and views the users to be its customers. Specifically, the Group controls the virtual items before they are transferred to users. Its control is evidenced by the Group’s sole ability to monetize the virtual items before they are transferred to users, and is further supported by the Group being primarily responsible to the users for the delivery of the virtual items as well as having full discretion in establishing pricing for the virtual items. Accordingly, the Group reports its live video service revenues on a gross basis with amounts billed to users for the virtual items recorded as revenues and the Revenue Sharing paid to broadcasters and talent agencies recorded as cost of revenues. Sales proceeds are initially recorded as deferred revenue and recognized as revenue based on the consumption of the virtual items. The Group has determined that the virtual items represent one performance obligation in the live video service. Revenue related to each of the virtual items is recognized at the point in time when the virtual item is transferred directly to the broadcasters and consumed by them. Although some virtual items have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual items are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented. The Group does not have further performance obligations to the user after the virtual items are consumed.
Users also have the right to purchase various combinations of virtual items in the live video, which are generally capable of being distinct. Specifically, the Group enters into certain contracts with its users where virtual item coupons are granted to users simultaneously with a purchase of a virtual item. The virtual item coupon can be used by the users to exchange for free virtual items in the future. Such virtual item coupons typically expire a few days after being granted. The Group has determined that the virtual item coupons represent a material right under Topic 606 which is recognized as a separate performance obligation at the outset of the arrangement. Judgment is required to determine the standalone selling price for each distinct virtual item and virtual item coupon. The Group allocates the consideration to each distinct virtual item and virtual item coupon based on their relative standalone selling prices. In instances where standalone selling price is not directly observable as the Group does not sell the virtual items separately, the Group determines the standalone selling price based on pricing strategies, market factors and strategic objectives. The Group recognizes revenue for each of the distinct virtual item in accordance with the revenue recognition method discussed above unless otherwise stated. Revenue for the virtual item coupons are recognized when the virtual items purchased with the virtual item coupons are consumed. Although virtual item coupons have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual currency coupons are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented. The Group does not provide any right of return and does not provide any other credit or incentive to its users.
Value-added services revenues mainly include membership subscription revenue and virtual gift service revenue. Membership subscription is a service package which enables members to enjoy additional functions and privileges. The contract period for the membership subscription ranges from one month to one year. All membership subscription is nonrefundable. The Group has determined that its membership subscription services represent one performance obligation. The Group collects membership subscription in advance and records it as deferred revenue. Revenue is recognized ratably over the contract period as the membership subscription services are delivered. Virtual gift service was launched in 2016 to enhance users’ experience of interaction and social networking with each other. Users are able to purchase virtual items and send them to other users. The Group shares a portion of the revenues derived from the sales of virtual items with the recipient of the virtual item. All virtual items are nonrefundable, consumed at a point-in-time and expire a few days after the purchase. Although some virtual items have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual items are consumed shortly after they are released to users, and the forfeiture rate remains relatively low for the periods presented. The Group collects the cash from the purchase of virtual items and recognized the sales of virtual items when the performance obligation is satisfied. The Group has determined that it has one single performance obligation which is the display of the virtual item for the users who purchase them. Revenues derived from the sale of virtual items are recorded on a gross basis as the Group has determined that it is the principal in providing the virtual gift services for the same reasons outlined in the revenue recognition policy for its live video services. The portion paid to gift recipients is recognized as cost of revenues.
The Group provides advertising and marketing solutions to customers for promotion of their brands and conduction of effective marketing activities through its mobile application. Display-based mobile marketing services For display-based online advertising services such as banners and location-based advertising on the mobile applications, the Group has determined that its mobile marketing services represent one performance obligation. Accordingly, the Group recognizes mobile marketing revenue ratably over the period that the advertising is provided commencing on the date the customer’s advertisement is displayed, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements. Performance-based mobile marketing services The Group also enables advertising customers to place link on its mobile platform on a pay-for-effectiveness basis, which is referred to as the cost for performance model. The Group charges fees to advertising customers based on the effectiveness of advertising links, which is measured by active clicks. The Group has determined that its mobile marketing services represent one performance obligation. Accordingly, the Group recognizes mobile marketing revenue based on sales of effective clicks. Revenue is estimated by the Group based on its internal data, which is confirmed with respective customers periodically, or is recognized based on a fixed unit price. The Group’s mobile marketing revenues are recognized net of agency rebates, if applicable. Agency rebates have not been material for the years ended December 31, 2016, 2017 and 2018.
The Group publishes both licensed mobile games developed by third-party game developers and its self-developed games to the game players through its mobile application. Licensed mobile games The Group generates revenue from offering services of mobile games developed by third-party game developers. All of the licensed games can be accessed and played by game players directly through the Group’s mobile game platform. The Group primarily views the game developers to be its customers and considers its responsibility under its agreements with the game developers to be the promotion of the game developers’ games. The Group generally collects payments from game players in connection with the sale of in-game currencies and remits certain agreed-upon percentages of the proceeds to the game developers. Purchases of in-game currencies are not refundable after they have been sold unless there is unused in-game currencies at the time a game is discontinued. Typically, a game will only be discontinued when the monthly revenue generated by a game becomes consistently insignificant. The Group does not currently expect to pay any material cash refunds to game players or game developers in connection with a discontinued game. The majority of the licensed mobile games revenue is derived from non-exclusive mobile games services further discussed below. Licensed mobile games - Non-exclusive mobile games services The Group enters into non-exclusive agreements with the game developers and offers the Group’s mobile game platform for the mobile games developed by the game developers. The Group considers its performance obligation under its arrangements with the game developers to be the offering of its mobile game platform for the game developers. The Group has determined that it has no additional performance obligation to the developers or game players upon the players completion of the corresponding in-game purchase. Therefore, the Group has determined that it is not the principal in the transaction and accordingly, revenues derived from the sale of in-game currencies are recorded net of remittances to game developers and commission fees made to third-party application stores and other payment channels. Revenue is further recognized at the end of the estimated consumption date by individual game (i.e., the estimated date in-game currencies are consumed within the game), which is typically within a short period of time ranging from two to three days after the purchase of the in-game currencies. Self-developed mobile game In February 2015, the Group launched one self-developed game on its platform and started to generate revenues by in-game sales of virtual items. The Group has determined that it has a single performance obligation to the players who purchased the virtual items to gain an enhanced game-playing experience over the playing period of the paying players. Accordingly, the Group recognizes revenues ratably over the estimated average period of player relationship starting from the point in time when the players purchase the virtual items and once all other revenue recognition criteria are met. The Group operated eight and four self-developed mobile games in 2017 and 2018, respectively. The estimated periods of the player relationship ranged from 56 to 79 days as of December 31, 2017, and was 77 days as of December 31, 2018, respectively. The Group has determined that it is the principal in fulfilling all obligations related to the mobile game operations for self-developed games. Accordingly, revenues are recognized on a gross basis. Commission fees paid to third-party application stores and other payment channels are recorded as cost of revenues.
Revenues from other services in the year ended December 31, 2018 mainly consisted of revenues generated from advertisement resulting from the broadcasting of one television program produced by the Group. During the year ended December 31, 2018, the Group signed an agreement with a television station, under which the Group is responsible for the production of the television program content, which was completed by December 31, 2018. The television station was responsible for providing advertising and marketing solutions to customers in addition to broadcasting the television program content. Revenue generated from the above is in the form of the advertising fees, shared between the television station and the Group based on a pre-determined percentage stated in the agreement. The Group determined that its television content production service represented one performance obligation. The broadcasting of the content was completed in the year ended December 31, 2018 and the revenue was recognized ratably during the period when the content was broadcasted on the television station. Practical expedients and exemptions The Group’s contracts have an original duration of one year or less. Accordingly, the Group does not disclose the value of unsatisfied performance obligations. Additionally, the Group generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling and marketing expenses. Contract balances Contract balances include accounts receivable and deferred revenue. Accounts receivable represent cash due from third-party application stores and other payment channels as well as from advertising customers and are recorded when the right to consideration is unconditional. The allowance for doubtful accounts reflects the best estimate of probable losses inherent to the account receivable balance. The Group recorded no impairment charges related to contract assets in the period. Deferred revenue primarily includes cash received from paying users related to the Group’s live video service and value-added service as well as cash received from the Group’s advertising customer. Deferred revenue is recognized as revenue over the estimated service period or when all of the revenue recognition criteria have been met. Revenue recognized in 2018 that was included in the deferred revenue balance as of January 1, 2018 was RMB 422,028. Cost of revenues Cost of revenues consist of expenditures incurred in the generation of the Group’s revenues, including but not limited to revenue sharing with the broadcasters and talent agencies resulting from the sale of virtual items, production cost in connection the television content, bandwidth costs, commission fee paid to third-party application stores and other payment channels except for those paid related to licensed mobile games which are recorded net of revenue, salaries and benefits paid to employee, depreciation and amortization. These costs are expensed as incurred except for the direct and incremental platform commission fees to third-party application stores and other payment channels and production cost in connection with the television content which are deferred in “Prepaid expenses and other current assets” on the consolidated balance sheets. Such deferred costs are recognized in the consolidated statements of operations in “Cost of revenues” in the period in which the related revenues are recognized. Government subsidies For the government subsidies not subject to further performance obligations or future returns, the Group records the amounts as other income when received from local government authority. Whereas for the government subsidies with certain future performance obligations, the Group recognizes those as liabilities when received until the performances obligations have been met at which time, those are recognized as other income. Government subsidies recorded as other income amounted to RMB2,000, RMB141,688 and RMB223,995 for the years ended December 31, 2016, 2017 and 2018. Research and development expenses Research and development expenses primarily consist of (i) salaries and benefits for research and development personnel, and (ii) technological service fee, office rental and depreciation expenses associated with the research and development activities. The Group’s research and development activities primarily consist of the research and development of new features for its mobile platform and its self-developed mobile games. The Group has expensed all research and development expenses when incurred. Value added taxes (“VAT”) Entities that are VAT general taxpayers are allowed to offset qualified input VAT paid to suppliers against their output VAT liabilities. Net VAT balance between input VAT and output VAT is recorded in accrued expenses and other current liabilities on the consolidated balance sheets. VAT is also reported as a deduction to revenue when incurred and amounted to RMB367,635, RMB812,249 and RMB1,136,034 for the years ended December 31, 2016, 2017 and 2018, respectively. Income taxes Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized. The impact of an uncertain income tax position on the income tax return is recognized at the largest amount that is more-likely than- not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes. Foreign currency translation and change in reporting currency The reporting currency of the Company is the Renminbi (“RMB”). The functional currency of the Company is the US dollar (“US$”). The Company’s operations are principally conducted through the subsidiaries, its VIEs and VIEs’ subsidiaries located in the PRC where the local currency is the functional currency. Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency at the rates of exchange in place at the balance sheet date. Transactions in currencies other than the functional currency during the year are converted into the functional currency at the applicable rates of exchange prevailing when the transactions occurred. Transaction gains and losses are recognized in the consolidated statement of operations. Assets and liabilities of the Group companies are translated from their respective functional currencies to the reporting currency at the exchange rates at the balance sheet dates, equity accounts are translated at historical exchange rates and revenues and expenses are translated at the average exchange rates in effect during the reporting period. The resulting foreign currency translation adjustment are recorded in other comprehensive income (loss). Starting from the fourth quarter of 2018, the Group changed its reporting currency from US$ to RMB, to reduce the impact of increased volatility of the RMB to US$ exchange rate on the Group’s reported operating results. The aligning of the reporting currency with the underlying operations will better depict the Group’s results of operations for each period. The related financial statements prior to October 1, 2018 have been recasted to RMB as if the financial statements originally had been presented in RMB since the earliest periods presented. The change in reporting currency resulted in cumulative foreign currency translation adjustment to the Group’s comprehensive income amounted to a gain of RMB175,963, a loss of RMB155,368 and a gain of RMB198,654 for the years ended December 31, 2016, 2017 and 2018, respectively. Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the noon buying rate of US$1.00 = RMB6.8755 on the last trading day of 2018 (December 31, 2018) representing the certificated exchange rate published by the Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at such rate, or at any other rates. Operating leases Leases where the rewards and risks of ownership of assets primarily remain with the lessor are accounted for as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the lease periods. Advertising expenses The Group expenses advertising expenses as incurred. Total advertising expenses incurred were RMB367,532, RMB1,036,053 and RMB1,236,167 for the years ended December 31, 2016, 2017 and 2018, respectively, and have been included in sales and marketing expenses in the consolidated statements of operations. Comprehensive income Comprehensive income includes net income, unrealized gain or loss on available-for-sale investments and foreign currency translation adjustments. Comprehensive income is reported in the consolidated statements of comprehensive income. Share-based compensation Share-based payment transactions with employees and executives are measured based on the grant date fair value of the equity instrument issued and recognized as compensation expense net of a forfeiture rate on a straight-line basis, over the requisite service period, with a corresponding impact reflected in additional paid-in capital. Share-based compensation with cash settlement features is classified as liabilities. The percentage of the fair value that is accrued as compensation cost at the end of each period is based on the percentage of the requisite service that has been rendered at that date. Changes in fair value of the liability classified award that occur during the requisite service period is recognized as compensation cost over that period. These awards typically vest over a period of four years, but may fully vest due to the achievement of certain performance conditions. Share-based compensation expense is recognized on an accelerated basis if it is probable that the performance conditions will be achieved during the vesting period. Share awards issued to consultants are measured at fair value at the earlier of the commitment date or the date the services are completed and recognized over the period the services are provided. The estimate of forfeiture rate is adjusted over the requisite service period to the extent that actual forfeiture rate differs, or is expected to differ, from such estimates. Changes in estimated forfeiture rate is recognized through a cumulative catch-up adjustment in the period of change. Changes in the terms or conditions of share options are accounted as a modification. The Group calculates the excess of the fair value of the modified option over the fair value of the original option immediately before the modification, measured based on the share price and other pertinent factors at the modification date. For vested options, the Group recognizes incremental compensation cost in the period that the modification occurred. For unvested options, the Group recognizes, over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date. Earnings per share Basic earnings per ordinary share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. The Group determined that the nonvested restricted shares are participating securities as the holders of the nonvested restricted shares have a nonforfeitable right to receive dividends with all ordinary shares but the nonvested restricted shares do not have a contractual obligation to fund or otherwise absorb the Group’s losses. Accordingly, the Group uses the two-class method whereby undistributed net income is allocated on a pro rata basis to the ordinary shares and nonvested restricted shares to the extent that each class may share the income for the period; whereas the undistributed net loss for the period is allocated to ordinary shares only because the nonvested restricted shares are not contractually obligated to share the loss. Diluted earnings per ordinary share reflect the potential dilution that could occur if securities were exercised or converted into ordinary shares. The Group had share options, restricted share units and convertible senior notes, which could potentially dilute basic earnings per share in the future. To calculate the number of shares for diluted earnings per ordinary share, the effect of the share options and restricted share units is computed using the treasury stock method, and the effect of the convertible senior notes is computed using the as-if-converted method. Recent accounting pronouncements adopted On January 1, 2018, the Company adopted Topic 606. Under the standard, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company applied the five step method outlined in Topic 606 to all revenue streams and elected to adopt the standard using the modified retrospective method. Refer to Note 2, Revenue recognition for further details. In January 2016, the FASB issued a new pronouncement ASU 2016-01 Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU also provides a new measurement alternative for equity investments that do not have readily determinable fair values and do not qualify for the net asset value practical expedient. The ASU requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 was further amended in February 2018 by ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. This update was issued to clarify certain narrow aspects of the guidance concerning the recognition of financial assets and liabilities established in ASU 2016-01. This includes an amendment to clarify that an entity measuring an equity security using the measurement alternative may change its measurement approach to a fair valuation method in accordance with Topic 820, Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issued. ASU 2016-01 and ASU 2018-03 are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance permits early adoption for certain provisions. Adoption of the amendment must be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for amendments related to equity instruments that do not have readily determinable fair values which should be applied prospectively. The Group adopted ASU 2016-01 and ASU 2018-03 under the modified retrospective method in the fiscal year of 2018. The adoption of 2016-01 and ASU 2018-03 did not have a significant impact on the Company’s consolidated results of operations, financial position or cash flows.
In November 2016, the FASB issued ASU 2016-18: Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update do not provide a definition of restricted cash or restricted cash equivalents. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Group adopted ASU 2016-18 under the retrospective method in the fiscal year of 2018. The adoption of 2016-18 did not have a significant impact on the Company’s cash flows for the years ended December 31, 2016, 2017 and 2018. In January 2017, the FASB issued ASU 2017-01: Business Combinations (Topic 805): Clarifying the Definition of a Business. The Update requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. Early application of the amendments in this update is allowed. The amendments in this Update should be applied prospectively on or after the effective date. No disclosures are required at transition. The Group adopted this guidance on January 1, 2018. The adoption did not have significant impact on the Company’s consolidated results of operations, financial position or cash flows. Recent accounting pronouncements not yet adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. ASU 2016-02 is effective for public business entities for annual reporting periods and interim periods within those years beginning after December 15, 2018. The Group will adopt ASU 2016-02 on January 1, 2019 using the modified retrospective method. The Group will elect the package of practical expedients permitted under the transition guidance, which allows the Group to carry forward the historical lease classification and, the assessment whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard. The Group will also elect the practical expedient not to separate lease and non-lease components for certain classes of underlying assets and the short-term lease exemption for contracts with lease terms of 12 months or less. Certain operating leases related to offices and internet data center (“IDC”) facilities will be subject to ASU 2016-02 and right-of-use assets and lease liabilities will be recognized on the Group’s consolidated balance sheet. The Company currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company’s balance sheet for certain in-scope operating leases. The Company does not expect any material impact on net assets and the consolidated statement of comprehensive income as a result of adopting the new standard. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements.
In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting to simplify the accounting for share-based payments to nonemployees (“ASU 2018-07”) by aligning it with the accounting for share-based payments to employees, with certain exceptions. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date, which may lower their cost and reduce volatility in the income statement. The guidance is effective for public business entities in annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The Group will adopt ASU 2018-07 on January 1, 2019 using grant date fair value to measure equity-classified nonemployee awards. The Group does not expect that the adoption of ASU 2018-07 will have a significant impact on the Group’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Company is currently in the process of evaluating the impact of the adoption of ASU 2018-13 on its consolidated financial statements. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials (“ASU 2019-02”) which improves GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for the Company’s fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Group is in the process of evaluating the impact of adoption of this guidance on its consolidated financial statements. |

| Goodwill |
To assess potential impairment of goodwill, the Group performs an assessment of the carrying value of the reporting units at least on an annual basis or when events occur or circumstances change that would more likely than not reduce the estimated fair value of the reporting units below its carrying value. The Group performed a goodwill impairment analysis as of December 31, 2018. When determining the fair value of both the Momo and Tantan reporting units, the Group used a discounted cash flow model that included a number of significant unobservable inputs. Key assumptions used to determine the estimated fair value include: (a) internal cash flows forecasts including expected revenue growth, operating margins and estimated capital needs, (b) an estimated terminal value using a terminal year long-term future growth rate determined based on the growth prospects of the reporting units; and (c) a discount rate that reflects the weighted-average cost of capital adjusted for the relevant risk associated with the Momo and Tantan reporting units’ operations and the uncertainty inherent in the Group’s internally developed forecasts. Based on the Group’s assessment as of December 31, 2018, the fair value of both business reporting units exceeded their carrying value. |

Convertible Senior Notes |

| Convertible Senior Notes |
In July 2018, the Company issued RMB4,985 million (US$725 million) of convertible senior notes (the “Notes”) which will mature in on July 1, 2025. The Notes will be convertible into the Company’s American depositary shares (“ADSs”), at the option of the holders, based on an initial conversion rate of 15.4776 of the Company’s ADSs per US$1,000 principal amount of Notes (which is equivalent to an initial conversion price of approximately US$64.61 per ADS and represents an approximately 42.5% conversion premium over the closing trading price of the Company’s ADSs on June 26, 2018, which was US$45.34 per ADS). The conversion rate for the Notes is subject to adjustments upon the occurrence of certain events. The holders of the Notes may convert their notes, in integral multiples of US$1,000 principal amount, at any time prior to the day immediately preceding the maturity date. The Company will not have the right to redeem the Notes prior to maturity, except in the event of certain changes to the tax laws or their application or interpretation. The holders of the Notes will have the right to require the Company to repurchase all or part of their Notes in cash on July 1, 2023, or in the event of certain fundamental changes. As of December 31, 2018, no Notes were converted into the Company’s ADSs. The Notes bear interest at a rate of 1.25% per year and will be payable semiannually. As of December 31, 2018, the carrying value of the Notes was RMB 4,877,116. The balance at December 31, 2018 included unamortized issuance costs of RMB107,622. The debt issuance costs are being amortized through interest expense over the period from July 2, 2018, the date of issuance, to July 1, 2025, the date of expiration, using the effective interest rate method which was 1.61% for the year ended December 31, 2018. Amortization and interest expenses related to the convertible senior notes amounted to RMB38,491 during the year ended December 31, 2018. The conversion option meets the definition of a derivative. However, since the conversion option is considered indexed to the Company’s own stock and classified in stockholders’ equity, the scope exception is met, accordingly the bifurcation of the conversion option from the Notes is not required. There is no beneficial conversion feature attributable to the Notes as the set conversion prices for the Notes are greater than the respective fair values of the ordinary share price at date of issuance. The feature of mandatory redemption upon maturity is clearly and closely related to the debt host and this feature does not need to be bifurcated. Based on above, the Company accounted for the Notes in accordance with ASC 470, as a single instrument under long-term debt. Issuance costs related to the Notes is recorded in consolidated balance sheet as a direct deduction from the principal amount of the Notes. |

Measured on recurring basis The Group measures its financial assets and liabilities including cash and cash equivalents at fair value on a recurring basis as of December 31, 2017 and 2018. Cash and cash equivalents are classified within Level 1 of the fair value hierarchy because they are valued based on the quoted market price in an active market. As of December 31, 2017 and 2018, information about inputs for the fair value measurements of the Group’s assets that are measured at fair value on a recurring basis in periods subsequent to their initial recognition is as follows:
Additional information about the reconciliation of the fair value measurement of long-term investments using significant unobservable inputs (level 3) on a recurring basis are is as follows:
Measured on nonrecurring basis The Group measures its equity method investments at fair value on a nonrecurring basis whenever events or changes in circumstances indicate that the carrying value may not be recoverable. As of December 31, 2017 and 2018, the Group performed an impairment test on its equity method investees and recorded an impairment loss of RMB nil and RMB nil, respectively. Such impairments are considered level 3 fair value measurements because the Group used unobservable inputs such as the management projection of discounted future cash flow and the discount rate. For goodwill impairment testing, refer to Note 8 for details. |

| Income Taxes |
Cayman In July 2014, the Company was redomiciled in the Cayman Islands as an exempted company registered under the laws of the Cayman Islands. Under the current laws of the Cayman Islands, it is not subject to tax on either income or capital gain. BVI Momo BVI is a tax-exempted company incorporated in the BVI. The United States (“US”) Momo US and Tantan US are incorporated in the U.S.A. In December 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code including, but not limited to, (1) reducing the U.S. federal corporate tax rate, (2) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years, and (3) bonus depreciation that will allow for full expensing of qualified property. The impact of the Tax Act is not material to the Group’s operation and resulted in a decrease in income tax rate from 35% before January I, 2018 to 21% after January 1, 2018 for tax and income earned as determined in accordance with the relevant tax rules and regulations. Hong Kong The Company’s subsidiaries domiciled in Hong Kong are subject to a two-tiered income tax rate for taxable income earned in Hong Kong effectively since April 1, 2018. The first 2 million Hong Kong dollars of profits earned by the company are subject to be taxed at an income tax rate of 8.25%, while the remaining profits will continue to be taxed at the existing tax rate, 16.5%. PRC In August 2014, Beijing Momo IT was qualified as a software enterprise. As such, Beijing Momo IT will be exempt from income taxes for two years beginning in its first profitable year which was from 2015 to 2016 followed by a tax rate of 12.5% for the succeeding three years which is from 2017 to 2019. According to No. 23 announcement of the State Administration of Taxation of PRC in April 2018, Chengdu Momo is no longer required to submit the preferential tax rate application to the tax authority, but only required to keep the relevant materials for future tax inspection instead. Based on the historically experience, the Group believes Chengdu Momo will most likely to be qualified as western China development enterprise and accordingly be entitled to a preferential income tax rate of 15% for the year 2018. As a result, the Group applied 15% to determine the tax liabilities for Chengdu Momo. In October 2018, Beijing Santi Cloud Union Technology Co., Ltd. (“Santi Cloud Union”) qualified as a High and New Technology enterprise (“HNTE”). As such, Santi Cloud Union enjoyed a preferential tax rate of 15% from 2018 to 2020. Santi Cloud Union was in accumulated loss position for the year ended December 31, 2018. The other entities incorporated in the PRC are subject to an enterprise income tax at a rate of 25%. Since January 1, 2011, the relevant tax authorities of the Group’s subsidiaries have not conducted a tax audit on the Group’s PRC entities. In accordance with relevant PRC tax administration laws, tax years from 2015 to 2017 of the Group’s PRC subsidiaries, VIEs and VIEs’ subsidiaries, remain subject to tax audits as of December 31, 2018, at the tax authority’s discretion. Under the Enterprise Income Tax Law (the “EIT Law”) and its implementation rules which became effective on January 1, 2008, dividends generated after January 1, 2008 and payable by foreign-invested enterprise in the PRC to its foreign investors who are non-resident enterprises are subject to a 10% withholding tax, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with PRC that provides for a different withholding arrangement. Under the taxation arrangement between the PRC and Hong Kong, a qualified Hong Kong tax resident which satisfies the criteria of “beneficial owner” and directly holds 25% or more of the equity interest in a PRC resident enterprise is entitled to a reduced withholding tax rate of 5% for dividends generated in the PRC. Cayman, where the Company is incorporated, does not have a tax treaty with PRC. Uncertainties exist with respect to how the current income tax law in the PRC applies to the Group’s overall operations, and more specifically, with regard to tax residency status. The EIT Law includes a provision specifying that legal entities organized outside of the PRC will be considered residents for Chinese income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the EIT Law provide that non-resident legal entities will be considered China residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc., occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Group does not believe that the legal entities organized outside of the PRC within the Group should be treated as residents for EIT law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC should be deemed resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income taxes, at a rate of 25%. If any entity within the Group that is outside the PRC were to be a non-resident for PRC tax purposes dividends paid to it out of profits earned after January 1, 2008 would be subject to a withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with the PRC. Aggregate undistributed earnings of the Company’s PRC subsidiaries and the VIEs that are available for reinvestment. Upon distribution of such earnings, the Company will be subject to the PRC EIT, the amount of which is impractical to estimate. The Company did not record any withholding tax on any of the aforementioned undistributed earnings because the relevant subsidiaries and the VIEs do not intend to declare dividends and the Company intends to permanently reinvest it within the PRC. Additionally, no deferred tax liability was recorded for taxable temporary differences attributable to the undistributed earnings because the Company believes the undistributed earnings can be distributed in a manner that would not be subject to income tax.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Group did not retrospectively apply the changes to prior years. Significant components of the Group’s deferred tax assets and liabilities are as follows:
The Group considers the following factors, among other matters, when determining whether some portion or all of the deferred tax assets will more likely than not be realized: the nature, frequency and severity of losses, forecasts of future profitability, the duration of statutory carry-forward periods, the Group’s experience with tax attributes expiring unused and tax planning alternatives. The Group’s ability to realize deferred tax assets depends on its ability to generate sufficient taxable income within the carry-forward periods provided for in the tax law. As of December 31, 2018, the tax loss carry-forward for the Company’s subsidiaries domiciled in PRC, VIEs, and VIEs’ subsidiaries amounted to RMB264,709. The tax losses in PRC can be carried forward for five years to offset future taxable profit, and the period was extended to 10 years for entities qualified as HNTE in 2018 and thereafter. The tax losses of entities in the PRC will begin to expire in 2020, if not utilized. As of December 31, 2018, the tax loss carryforward for the Company’s subsidiaries domiciled in Hong Kong amounted to RMB109,697, which would be carried forward indefinitely and set off against its future taxable profits. As of December 31, 2018, the tax loss carry-forward for the Company’s subsidiaries domiciled in US amounted to RMB70,055. RMB 61,774 was generated from the years before 2018, which can be carried back two years and forward twenty years. The remaining RMB 8,281 was generated in the year ended December 31, 2018, which can be carried forward indefinitely but cannot be carried back, and can be used to offset only 80 percent of the taxable income. The Group does not file combined or consolidated tax returns, therefore, losses from individual subsidiaries or the VIEs may not be used to offset other subsidiaries’ or VIEs’ earnings within the Group. Valuation allowance is considered on each individual subsidiary and legal entity basis. Valuation allowances have been established in respect of certain deferred tax assets as it is considered more likely than not that the relevant deferred tax assets will not be realized in the foreseeable future. Reconciliation between income tax expense computed by applying the PRC EIT rate of 25% to income before income taxes and the actual provision for income tax is as follows:
If Beijing Momo IT and Chengdu Momo did not enjoy income tax exemptions and preferential tax rates for the years ended December 31, 2016, 2017 and 2018, the increase in income tax expenses and resulting net income per share amounts would be as follows:
No significant unrecognized tax benefit was identified for the years ended December 31, 2016, 2017 and 2018. The Group did not incur any interest and penalties related to potential underpaid income tax expenses and also believed that uncertainty in income taxes did not have a significant impact on the unrecognized tax benefits within next twelve months. |

| Share-Based Compensation |
Share options granted by the Company In November 2012, the Company adopted a share incentive plan (“2012 Plan”), which was amended in October 2013. The maximum aggregate number of shares which may be issued pursuant to all awards under the 2012 Plan is 44,758,220 ordinary shares. In November, 2014, the Company adopted the 2014 share incentive plan (“2014 Plan”), pursuant to which a maximum aggregate of 14,031,194 Class A ordinary shares may be issued pursuant to all awards granted thereunder. Starting from 2017, the number of shares reserved for future issuances under the 2014 Plan will be increased by a number equal to 1.5% of the total number of outstanding shares on the last day of the immediately preceding calendar year, or such lesser number of Class A ordinary shares as determined by the Company’s board of directors, on the first day of each calendar year during the term of the 2014 Plan. With the adoption of the 2014 Plan, the Company will no longer grant any incentive shares under the 2012 Plan. The time and condition to exercise options will be determined by the Board or a committee of the Board. The term of the options may not exceed ten years from the date of the grant, except for the situation of amendment, modification and termination. Under the 2014 Plan, share options are subject to vesting schedules ranging from two to four years. The following table summarizes the option activity for the year ended December 31, 2018:
There were 10,227,313 vested options, and 10,477,208 options expected to vest as of December 31, 2018. For options expected to vest, the weighted-average exercise price was US$0.0002 as of December 31, 2018 and aggregate intrinsic value was US$136,006 and US$124,415 as of December 2017 and 2018, respectively. The weighted-average grant-date fair value of the share options granted during the years 2016, 2017, and 2018 was US$6.24, US$17.41 and US$17.75, respectively. Total intrinsic value of options exercised for the years ended December 31, 2016, 2017 and 2018 was US$45,581, US$154,233 and US$209,797, respectively. The total fair value of options vested during the years ended December 31, 2016, 2017 and 2018 was US$27,171, US$37,979 and US$59,226, respectively. In July 2016, the Company canceled 187,500 outstanding employee share options granted under the 2014 Plan for one employee. As a result, the Company immediately recognized the unvested compensation cost attributable to the canceled award amounting to RMB10,002 in 2016. The fair value of options granted was estimated on the date of grant using the Black-Sholes pricing model after the Company completed its IPO, with the following assumptions used for grants during the applicable periods:
Risk-free interest rate was estimated based on the yield to maturity of China international government bonds with a maturity period close to the expected term of the options.
The Company used the original contractual term.
The volatility of the underlying ordinary shares during the life of the options was estimated based on the historical stock price volatility of comparable listed companies over a period comparable to the expected term of the options.
The dividend yield was estimated by the Group based on its expected dividend policy over the expected term of the options.
The exercise price of the options was determined by the Group’s board of directors. The fair value of the ordinary shares is determined as the closing sales price of the ordinary shares as quoted on the principal exchange or system. For employee and executives share options, the Group recorded share-based compensation of RMB186,687, RMB286,119 and RMB377,241 during the years ended December 31, 2016, 2017 and 2018, respectively, based on the fair value on the grant dates over the requisite service period of award according to the vesting schedule for employee share option. For non-employee share options the Group recorded share-based compensation of RMB20,767, RMB44,277 and RMB14,360 during the years ended December 31, 2016, 2017 and 2018, respectively, based on the fair value at the commitment date and recognized over the period the service is provided. As of December 31, 2018, total unrecognized compensation expense relating to unvested share options was RMB1,054,778, which will be recognized over a weighted average period of 2.81 years. The weighted-average remaining contractual term of options outstanding is 7.36 years.
Non-vested restricted shares granted by the Company In April 2012, the Company’s four founding shareholders entered into an arrangement with the investor in conjunction with the issuance of Series A preferred shares, whereby all of their 147,000,000 ordinary shares (“Founders’ shares”) became subject to service and transfer restrictions. Such Founders’ shares are subject to repurchase by the Company upon early termination of their four years of employment. The repurchase price is the par value of the ordinary shares. 25% of the Founders’ shares shall be vested annually. The restricted share agreements were subsequently amended on June 11, 2012 and July 18, 2012, respectively. Pursuant to the agreements, 25% of the Founders’ shares shall vest upon the closing of issuance of Series B preferred shares and the remaining 75% shall be vested monthly in equal installments over the next 36 months. This arrangement has been accounted for as a grant of restricted stock awards subject to service vesting conditions. Because the modification does not affect any of the other terms or conditions of the award, presumably the fair value before and after the modification is the same. The restrictions on the ordinary shares were fully released and such shares became fully vested in 2016. On May 15, 2014, the Company’s four founding shareholders entered into an agreement with the investors to renew the arrangement. The Company considered the amendment of agreement as a modification of vesting of the restricted shares. Pursuant to the agreement, the Company shall be entitled to repurchase 50% and 25% of such shares in the case that founders terminate their employments with the Company before April 17, 2015 and during the period from April 17, 2015 to April 17, 2016, respectively, at a price of US$0.0001 per share or the lowest price permitted under applicable laws. Therefore, the Company considered that 50% of the total restricted shares were vested immediately on the amendment date and 25% shall be vested annually on April 17 in the next two years ending April 17, 2016. Before the modification date, May 15, 2014, there were 131,348,411 ordinary shares, of which 45,937,500 were unvested restricted shares. As the result of modification, 19,736,705 vested ordinary shares were classified to unvested restricted shares on the modification date and the corresponding compensation costs for these unvested restricted shares were amortized over the remaining service period. Because the modification does not affect any of the other terms or conditions of the award, the fair value of the restricted shares before and after the modification is the same. A summary of non-vested restricted share activity during the years ended December 31, 2016, 2017 and 2018 is presented below:
The weighted average grant date fair value of the non-vested restricted shares was US$0.01 per share and the aggregated fair value was US$1,470. The total fair value of non-vested restricted shares vested during the years ended December 31, 2016, 2017 and 2018 was US$286, US$ nil and US$ nil, respectively. The Company recorded compensation expense of RMB348, RMB nil and RMB nil during the years ended December 31, 2016, 2017 and 2018, respectively, related to non-vested restricted shares. As of December 31, 2018, total unrecognized compensation expense relating to the non-vested restricted shares was RMB nil. Restricted share units (“RSUs”) granted by the Company On December 11, 2014, the Company granted a total of 40,001 shares of RSUs to independent directors under the 2014 Plan. The restricted share units will vest in accordance with the vesting schedule set out in the RSUs award agreement, which is 50% of the RSUs shall vest at the end of every six months since the grant date. On May 17, 2016, March 7, 2017 and May 2, 2018, the Company further granted 200,000, 100,000 and 100,000 shares of RSUs, respectively, to the independent directors under the 2014 Plan with a vesting period of 4 years. The Company will forfeit the unvested portion of the RSUs if the grantees terminate their service during the vesting period. The Group recorded share-based compensation of RMB2,295, RMB4,173 and RMB6,609 for RSUs for the years ended December 31, 2016, 2017 and 2018, respectively, based on the fair value on the grant dates over the requisite service period of award using the straight-line method. As of December 31, 2018, total unrecognized compensation expense relating to unvested RSUs was RMB17,979 which will be recognized over a weighted average period of 2.69 years. Share options granted by Tantan Limited In March, 2015, Tantan Limited adopted the 2015 share incentive plan (“2015 Plan”), pursuant to which a maximum aggregate of 1,000,000 shares may be issued pursuant to awards may be authorized, but unissued ordinary shares. The Board of Directors may in its discretion make adjustments to the numbers of shares. In April 2016 and March 2017, the Board of Directors of Tantan approved to adjust the numbers of shares to a maximum aggregate of 2,000,000 and 2,793,812, respectively. In July, 2018, Tantan Limited adopted the 2018 share incentive plan (“2018 Plan”), pursuant to which the maximum aggregate number of shares which may be issued shall initially be 5,963,674 ordinary shares, plus that number of ordinary shares authorized for issuance under the 2015 Plan, in an amount equal to (i) the number of ordinary shares that were not granted pursuant to the 2015 Plan, plus (ii) the number of ordinary shares that were granted pursuant to the 2015 Plan that have expired without having been exercised in full or have otherwise become unexercisable. The time and condition to exercise options will be determined by Tantan’s Board. The term of the options may not exceed ten years from the date of the grant, except for the situation of amendment, modification and termination. Options classified as equity awards The following table summarizes the option activity for the year ended December 31, 2018:
There were 358,281 vested options, and 1,353,711 options expected to vest as of December 31, 2018. For options expected to vest, the weighted-average exercise price was US$8.58 as of December 31, 2018 and the aggregate intrinsic value amounted to US$23,534 as of December 31, 2018. The weighted-average grant-date fair value of the share options granted during the year ended December 31, 2018 was US$14.99. Total intrinsic value of options exercised for the year ended December 31, 2018 was US$ nil. The total fair value of options vested during the year ended December 31, 2018 was US$7,600. The fair value of each option granted was estimated on the date of grant using the binomial tree pricing model with the following assumptions used for grants during the applicable periods:
Risk-free interest rate was estimated based on the yield to maturity of China international government bonds with a maturity period close to the expected term of the options.
Tantan Limited used the original contractual term.
The volatility of the underlying ordinary shares during the life of the options was estimated based on the historical stock price volatility of comparable listed companies over a period comparable to the expected term of the options.
The dividend yield was estimated by Tantan Limited based on its expected dividend policy over the expected term of the options.
The exercise price of the options was determined by the Tantan Limited’s board of directors.
The estimated fair value of the ordinary shares underlying the options as of the respective grant dates was determined based on a retrospective valuation, which used management’s best estimate for projected cash flows as of each valuation date. For share options classified as equity awards, Tantan Limited recorded share-based compensation of RMB94,977 during the year ended December 31, 2018 , based on the fair value of the grant dates over the requisite service period of award according to the vesting schedule for employee share option. As of December 31, 2018, total unrecognized compensation expense relating to unvested share options was RMB236,053 which will be recognized over a weighted average period of 2.79 years. The weighted-average remaining contractual term of options outstanding is 7.45 years.
Options classified as liability awards In August 2018, Tantan Limited granted 3,578,205 share options to its founders under the 2018 Plan. The founders have the right to request Tantan Limited to redeem for cash the vested options upon the termination of the founders’ employment at a price based on a fixed equity value of Tantan Limited. Therefore, the awards are classified as liability on the consolidated balance sheet due to their cash settlement feature. The options include a four years vesting condition whereas options vest ratably at the end of each year. Accordingly, the awards are re-measured at each reporting date with a corresponding charge to stock-based compensation expense and are amortized over four years. The share options also include a performance condition in which the founders have the right to receive fully vested options immediately upon achieving certain performance conditions. As of December 31, 2018, the Group assessed and concluded that it is not probable that the achievement of the performance condition will be met prior to the end of the four years vesting term. No liability classified options were vested, and 3,578,205 options were outstanding and expected to vest as of December 31, 2018. For options expected to vest, the weighted-average exercise price was US$0.002 and the aggregate intrinsic value amounted to US$92,883 as of December 31, 2018. The weighted-average grant-date fair value of the share options granted for the year ended December 31, 2018 was US$37.15. The fair value of each option granted was estimated using the binomial tree pricing model with the following assumptions used during the applicable periods:
Risk-free interest rate was estimated based on the yield to maturity of China international government bonds with a maturity period close to the expected term of the options.
Tantan Limited used the original contractual term.
The volatility of the underlying ordinary shares during the life of the options was estimated based on the historical stock price volatility of comparable listed companies over a period comparable to the expected term of the options.
The dividend yield was estimated by Tantan Limited based on its expected dividend policy over the expected term of the options.
The exercise price of the options was determined by the Board of Directors of Tantan Limited.
The estimated fair value of the ordinary shares underlying the options as of the respective grant dates was determined based on a retrospective valuation, which used management’s best estimate for projected cash flows as of each valuation date. For share options classified as liability awards, Tantan Limited recorded share-based compensation of RMB86,778 during the year ended December 31, 2018, based on the fair value at the grant date and adjusted subsequently at each reporting dates. As of December 31, 2018, total unrecognized compensation expense relating to unvested share options was RMB818,092, which is expected to be recognized over a weighted average period of 3.62 years. Total unrecognized compensation expenses and recognition period may be adjusted for future changes in estimated forfeitures, and the probability and time of achieving the performance condition .The weighted-average remaining contractual term of options outstanding is 9.62 years. |

| Net Income Per Share |
For the year ended December 31, 2016, the Group determined that the nonvested restricted shares are participating securities as the holders of the nonvested restricted shares have a nonforfeitable right to receive dividends with all ordinary shares but the nonvested restricted shares do not have a contractual obligation to fund or otherwise absorb the Group’s losses. Accordingly, the Group uses the two-class method of computing net income per share, for ordinary shares and nonvested restricted shares according to the participation rights in undistributed earnings. The calculation of net income per share is as follows:
The following table summarizes potential ordinary shares outstanding excluded from the computation of diluted net income per ordinary share for the years ended December 31, 2016, 2017 and 2018, because their effect is anti-dilutive:
For the year ended December 31, 2017, an incremental weighted average number of 20,715,755 ordinary shares from the assumed exercise of share options and RSUs were included. For the year ended December 31, 2018, an incremental weighted average number of 14,821,852 ordinary shares from the assumed exercise of share options and RSUs and an incremental weighted average number of 11,251,916 ordinary shares resulting from the assumed conversion of convertible senior notes were included. |

| Segment Information |
The Group’s chief operating decision maker has been identified as the Chief Executive Officer (“CEO”) who reviews financial information of operating segments based on US GAAP amounts when making decisions about allocating resources and assessing performance of the Group. During the years ended December 31, 2016 and 2017, the Group operated and managed its business as a single reporting segment, which included the provision of live video service, value-added services, mobile marketing services, mobile games and other services. The Group did not have discrete financial information of costs and expenses between various services in its internal reporting, and reported costs and expenses by nature as a whole. Therefore, the Group had one operating segment. During the year ended December 31, 2018, as a result of the Tantan acquisition discussed in Note 3, the Group determined that Tantan met the criteria for separate reportable segment given its financial information is separately reviewed by the Group’s CEO. Additionally, the Group started its entertainment business that included TV content production through one of its subsidiary QOOL, for which the Group’s CEO started to review discrete financial information. As a result, the Group determined that for the year ended December 31, 2018, it operated in three operating segments namely Momo, Tantan and QOOL. Momo’s services mostly include live video services, value-added service, mobile marketing services and mobile games derived from the Momo’s platform. Tantan’s services mostly include value-added services provided on Tantan’s platform. QOOL services mainly include advertisement services generated from the Group’s broadcasting of content television. The Group primarily operates in the PRC and substantially all of the Group’s long-lived assets are located in the PRC. The Group’s chief operating decision maker evaluates performance based on each reporting segment’s net revenue, operating cost and expenses, operating income and net income. Prior to Tantan acquisition, Tantan’s financial information was not consolidated to the Group’s financial statements, therefore Tantan’s service lines do not have comparable financial information in 2016 and 2017. QOOL started its entertainment business since 2017 and the comparable financial information in 2016 and 2017 account for an insignificant portion to the Group’s consolidated financial statements. Net revenues, operating cost and expenses, operating income, and net income by segment for the years ended December 31, 2016, 2017 and 2018 were as follows:

| Receivables [Abstract] | |||
| Statutory Reserves and Restricted Net Assets |
In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of association, the Group’s subsidiaries and VIEs located in the PRC, being foreign invested enterprises established in the PRC, are required to provide for certain statutory reserves. These statutory reserve funds include one or more of the following: (i) a general reserve, (ii) an enterprise expansion fund or discretionary reserve fund, and (iii) a staff bonus and welfare fund. Subject to certain cumulative limits, the general reserve fund requires a minimum annual appropriation of 10% of after-tax profit (as determined under accounting principles generally accepted in China at each year-end); the other fund appropriations are at the subsidiaries’ or the affiliated PRC entities’ discretion. These statutory reserve funds can only be used for specific purposes of enterprise expansion, staff bonus and welfare, and are not distributable as cash dividends except in the event of liquidation of our subsidiaries, our affiliated PRC entities and their respective subsidiaries. The Group’s subsidiaries, VIEs and VIEs’ subsidiaries are required to allocate at least 10% of their after tax profits to the general reserve until such reserve has reached 50% of their respective registered capital. Appropriations to the enterprise expansion reserve and the staff welfare and bonus reserve are to be made at the discretion of the board of directors of each of the Group’s subsidiaries. The appropriations to these reserves by the Group’s PRC subsidiaries, VIEs and VIEs’ subsidiaries were RMB119,308, RMB185,270 and RMB5,194 for the years ended December 31, 2016, 2017 and 2018. Relevant PRC laws and regulations restrict the WFOEs, VIEs and VIEs’ subsidiaries from transferring a portion of their net assets, equivalent to the balance of their statutory reserves and their paid in capital, to the Company in the form of loans, advances or cash dividends. The WFOEs’ accumulated profits may be distributed as dividends to the Company without the consent of a third party. The VIEs and VIEs’ subsidiaries’ revenues and accumulated profits may be transferred to the Company through contractual arrangements without the consent of a third party. Under applicable PRC law, loans from PRC companies to their offshore affiliated entities require governmental approval, and advances by PRC companies to their offshore affiliated entities must be supported by bona fide business transactions. The capital and statutory reserves restricted which represented the amount of net assets of the Group’s PRC subsidiaries, VIEs and VIEs’ subsidiaries in the Group not available for distribution were RMB677,213, RMB862,484 and RMB1,477,339 as of December 31, 2016, 2017 and 2018, respectively. |

The carrying values of term deposits, accounts receivable, accounts payable, deferred revenue, income tax payable, amount due from related parties and amount due to related parties approximate their fair values due to short-term maturities. It is not practical to estimate the fair value of the Group’s equity securities without readily determinable fair value because of the lack of quoted market price and the inability to estimate fair value without incurring excessive costs. |

| Business combinations | Business combinations Business combinations are recorded using the acquisition method of accounting in accordance with Accounting Standards Codification (“ASC”) 805 “Business Combinations”. The cost of an acquisition is measured as the aggregate of the acquisition date fair value of the assets transferred to the sellers and liabilities incurred by the Company and equity instruments issued. Identifiable assets and liabilities acquired or assumed are measured separately at their fair values as of the acquisition date, irrespective of the extent of any noncontrolling interests. The purchase price of business acquisition is allocated to the tangible assets, liabilities, identifiable intangible assets acquired and non-controlling interest, if any, based on their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred. The Company adopted Accounting Standard Update (“ASU”) 2017-01 “Business Combination (Topic 805): Clarifying the Definition of a Business” on January 1, 2018 and applied the new definition of a business prospectively for acquisitions made subsequent to December 31, 2017. Upon the adoption of ASU 2017-01, a new screen is introduced to evaluate whether a transaction should be accounted for as an acquisition and/or disposal of a business versus assets. In order for a purchase to be considered an acquisition of a business, and receive business combination accounting treatment, the set of transferred assets and activities must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the set of transferred assets and activities is not a business. The adoption of this standard requires future purchases to be evaluated under the new framework. |

| Equity securities without readily determinable fair value | Equity securities without readily determinable fair value The Company adopted ASC Topic 321, Investments—Equity Securities (“ASC 321”) on January 1, 2018. Prior to 2018, the Company carried at cost its investments in investees that do not have readily determinable fair value and over which the Company does not have significant influence, in accordance with ASC Subtopic 325-20, Investments-Other: Cost Method Investments. Management regularly evaluates the impairment of the cost method investments based on the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of the investment. Subsequent to the Company’s adoption of ASC 321 for equity securities without readily determinable fair value do not qualify for the existing practical expedient available in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) there the Company elected to use the measurement alternative to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. Pursuant to ASC 321, for those equity securities that the Company elects to use the measurement alternative, the Company makes a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, the Company has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the Company recognizes an impairment loss in net income equal to the difference between the carrying value and fair value. |

| Equity method investments | Equity method investments The investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee between 20% and 50%. Other factors, such as representation in the investee’s Board of Directors, voting rights and the impact of commercial arrangements, are also considered in determining whether the equity method of accounting is appropriate. For the investment in limited partnerships, where the Group holds less than a 20% equity or voting interest, the Group’s influence over the partnership operating and financial policies is determined to be more than minor. Accordingly, the Group accounts for these investments as equity method investments. Under the equity method of accounting, the affiliated company’s accounts are not reflected within the Group’s consolidated balance sheets and statements of operations; however, the Group’s share of the earnings or losses of the affiliated company is reflected in the caption “share of income on equity method investments” in the consolidated statements of operations. An impairment change is recorded if the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than-temporary. The Group estimates the fair value of the investee company based on comparable quoted price for similar investment in active market, if applicable, or discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital. |

| Available-for-sale investments | Available-for-sale investments For investments in investees’ stocks which are determined to be debt securities, the Group accounts for them as long-term available-for-sale investments when they are not classified as either trading or held-to-maturity investments. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Realized gains and losses and provision for decline in value judged to be other than temporary, if any, are recognized in the consolidated statements of operations.
The Group continually reviews its available-for-sale investments to determine whether a decline in fair value below the carrying value is other than temporary. The primary factors the Group considers in its determination are the length of time that the fair value of the investment is below the Group’s carrying value; the financial condition, operating performance and the prospects of the available-for-sale investee; and other specific information such as recent financing rounds. If the decline in fair value is deemed to be other than temporary, the carrying value of the available-for-sale investee is written down to fair value. The Group estimated the fair value of these investee companies based on discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital. |

| Intangible assets | Intangible assets Intangible assets acquired through business acquisitions are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion. Purchased intangible assets and intangible assets arising from acquisitions are recognized and measured at fair value upon acquisition. Separately identifiable intangible assets that have determinable lives continue to be amortized over their estimated useful lives using the straight-line method as follows:

| Impairment of long-lived assets with finite lives | Impairment of long-lived assets with finite lives The Group reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Group measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the fair value of the assets. |

| Goodwill | Goodwill Goodwill represents the excess of the purchase consideration over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed of the acquired entity as a result of the Company’s acquisitions of interests in its subsidiaries. Goodwill is not amortized but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that it might be impaired. The Company has an option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. Based on the qualitative assessment, if it is more likely than not that the fair value of each reporting unit is less than the carrying amount, the quantitative impairment test is performed. In performing the two-step quantitative impairment test, the first step compares the fair values of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. This allocation process is only performed for the purposes of evaluating goodwill impairment and does not result in an entry to adjust the value of any assets or liabilities. Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets, liabilities and goodwill to reporting units, and determining the fair value of each reporting unit. |

| Convertible senior notes | Convertible senior notes The Group determines the appropriate accounting treatment of its convertible senior notes in accordance with the terms in relation to the conversion feature, call and put options, and beneficial conversion feature. After considering the impact of such features, the Group may account for such instrument as a liability in its entirety, or separate the instrument into debt and equity components following the respective guidance described under ASC 815 “Derivatives and Hedging” and ASC 470 “Debt”. The debt discount, if any, together with the related issuance cost are subsequently amortized as interest expense, using the effective interest method, from the issuance date to the earliest maturity date. Interest expenses are recognized in the consolidated statement of operation in the period in which they are incurred. |

| Fair value | Fair value Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. Authoritative literature provides a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. An asset or liability categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement as follows: Level 1 Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2 Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.
Level 3 Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. |

| Revenue recognition | Revenue recognition Adoption of ASC, “Revenue from Contracts with Customers” In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606”) as modified by subsequently issued ASUs 2015-14, 2016-08,2016-10, 2016-12 and 2016-20 (collectively “ASU 2014-09”). On January 1, 2018, the Group adopted Topic 606 by applying the modified retrospective method to contracts that were not completed as of January 1, 2018. Results for the reporting periods beginning after January 1, 2018 are presented under Topic 606 while prior period amounts are not adjusted and continue to be reporting in accordance with the Group’s historical accounting under Topic 605. The adoption of Topic 606 did not have a material impact on the Group’s consolidated results of operations, financial position or cash flows but resulted in additional disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Group principally derives its revenue from live video services, value-added services, mobile marketing services, mobile games and other services. The Group recognizes revenue when control of the promised goods or services are transferred to the customers, in an amount that reflects the consideration that the Group expects to receive in exchange for those goods or services. The Group applied the five steps method outlined in Topic 606 to all revenue streams. In addition, the standard requires disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. For the years ended December 31, 2016, 2017 and 2018, all the revenue for the periods was recognized from contracts with customers. The Group’s revenue is reported net of discounts, value added tax and surcharges. The following table provides information about disaggregated revenue by types, including a reconciliation of the disaggregated revenue with the Group’s reportable segments:
The Group is principally engaged in providing live video services whereby users can enjoy live performances and interact with the broadcasters for free during the performance. Broadcasters can either host the performance on their own or join a talent agency. The Group generates revenue from sales of virtual items to its customers. The Group designs, creates and offers various virtual items for sales to users with pre-determined stand-alone selling price, which if users chose to, can be purchased and be presented to the broadcasters to show their support during their live video performance. The Group has a recharge system for users to purchase the Group’s virtual currency that can then be used to purchase virtual items on the Group’s platform. Users can recharge via various third-party application stores and other payment channels. Virtual currency is non-refundable and does not have any expiration date. Based on the turnover history of virtual currency, the Group determined that the virtual currency is often consumed soon after it is purchased and accordingly, the Group concluded that any breakage would be insignificant. Unconsumed virtual currency is recorded as deferred revenue. Virtual currencies used to purchase virtual items are recognized as revenue according to the prescribed revenue recognition policies of virtual items addressed below unless otherwise stated. All virtual items are non-refundable, consumed at a point-in-time and expire in a few days after the purchase. Under arrangements entered into with broadcasters and talent agencies, the Group shares a portion of the revenues derived from the sales of virtual items with them (“Revenue Sharing”). The Group has evaluated and determined that it is the principal and views the users to be its customers. Specifically, the Group controls the virtual items before they are transferred to users. Its control is evidenced by the Group’s sole ability to monetize the virtual items before they are transferred to users, and is further supported by the Group being primarily responsible to the users for the delivery of the virtual items as well as having full discretion in establishing pricing for the virtual items. Accordingly, the Group reports its live video service revenues on a gross basis with amounts billed to users for the virtual items recorded as revenues and the Revenue Sharing paid to broadcasters and talent agencies recorded as cost of revenues. Sales proceeds are initially recorded as deferred revenue and recognized as revenue based on the consumption of the virtual items. The Group has determined that the virtual items represent one performance obligation in the live video service. Revenue related to each of the virtual items is recognized at the point in time when the virtual item is transferred directly to the broadcasters and consumed by them. Although some virtual items have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual items are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented. The Group does not have further performance obligations to the user after the virtual items are consumed.
Users also have the right to purchase various combinations of virtual items in the live video, which are generally capable of being distinct. Specifically, the Group enters into certain contracts with its users where virtual item coupons are granted to users simultaneously with a purchase of a virtual item. The virtual item coupon can be used by the users to exchange for free virtual items in the future. Such virtual item coupons typically expire a few days after being granted. The Group has determined that the virtual item coupons represent a material right under Topic 606 which is recognized as a separate performance obligation at the outset of the arrangement. Judgment is required to determine the standalone selling price for each distinct virtual item and virtual item coupon. The Group allocates the consideration to each distinct virtual item and virtual item coupon based on their relative standalone selling prices. In instances where standalone selling price is not directly observable as the Group does not sell the virtual items separately, the Group determines the standalone selling price based on pricing strategies, market factors and strategic objectives. The Group recognizes revenue for each of the distinct virtual item in accordance with the revenue recognition method discussed above unless otherwise stated. Revenue for the virtual item coupons are recognized when the virtual items purchased with the virtual item coupons are consumed. Although virtual item coupons have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual currency coupons are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented. The Group does not provide any right of return and does not provide any other credit or incentive to its users.
Value-added services revenues mainly include membership subscription revenue and virtual gift service revenue. Membership subscription is a service package which enables members to enjoy additional functions and privileges. The contract period for the membership subscription ranges from one month to one year. All membership subscription is nonrefundable. The Group has determined that its membership subscription services represent one performance obligation. The Group collects membership subscription in advance and records it as deferred revenue. Revenue is recognized ratably over the contract period as the membership subscription services are delivered. Virtual gift service was launched in 2016 to enhance users’ experience of interaction and social networking with each other. Users are able to purchase virtual items and send them to other users. The Group shares a portion of the revenues derived from the sales of virtual items with the recipient of the virtual item. All virtual items are nonrefundable, consumed at a point-in-time and expire a few days after the purchase. Although some virtual items have expiry dates, the Group considers that the impact of breakage for the virtual items is insignificant as historical data shows that virtual items are consumed shortly after they are released to users, and the forfeiture rate remains relatively low for the periods presented. The Group collects the cash from the purchase of virtual items and recognized the sales of virtual items when the performance obligation is satisfied. The Group has determined that it has one single performance obligation which is the display of the virtual item for the users who purchase them. Revenues derived from the sale of virtual items are recorded on a gross basis as the Group has determined that it is the principal in providing the virtual gift services for the same reasons outlined in the revenue recognition policy for its live video services. The portion paid to gift recipients is recognized as cost of revenues.
The Group provides advertising and marketing solutions to customers for promotion of their brands and conduction of effective marketing activities through its mobile application. Display-based mobile marketing services For display-based online advertising services such as banners and location-based advertising on the mobile applications, the Group has determined that its mobile marketing services represent one performance obligation. Accordingly, the Group recognizes mobile marketing revenue ratably over the period that the advertising is provided commencing on the date the customer’s advertisement is displayed, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements. Performance-based mobile marketing services The Group also enables advertising customers to place link on its mobile platform on a pay-for-effectiveness basis, which is referred to as the cost for performance model. The Group charges fees to advertising customers based on the effectiveness of advertising links, which is measured by active clicks. The Group has determined that its mobile marketing services represent one performance obligation. Accordingly, the Group recognizes mobile marketing revenue based on sales of effective clicks. Revenue is estimated by the Group based on its internal data, which is confirmed with respective customers periodically, or is recognized based on a fixed unit price. The Group’s mobile marketing revenues are recognized net of agency rebates, if applicable. Agency rebates have not been material for the years ended December 31, 2016, 2017 and 2018.
The Group publishes both licensed mobile games developed by third-party game developers and its self-developed games to the game players through its mobile application. Licensed mobile games The Group generates revenue from offering services of mobile games developed by third-party game developers. All of the licensed games can be accessed and played by game players directly through the Group’s mobile game platform. The Group primarily views the game developers to be its customers and considers its responsibility under its agreements with the game developers to be the promotion of the game developers’ games. The Group generally collects payments from game players in connection with the sale of in-game currencies and remits certain agreed-upon percentages of the proceeds to the game developers. Purchases of in-game currencies are not refundable after they have been sold unless there is unused in-game currencies at the time a game is discontinued. Typically, a game will only be discontinued when the monthly revenue generated by a game becomes consistently insignificant. The Group does not currently expect to pay any material cash refunds to game players or game developers in connection with a discontinued game. The majority of the licensed mobile games revenue is derived from non-exclusive mobile games services further discussed below. Licensed mobile games - Non-exclusive mobile games services The Group enters into non-exclusive agreements with the game developers and offers the Group’s mobile game platform for the mobile games developed by the game developers. The Group considers its performance obligation under its arrangements with the game developers to be the offering of its mobile game platform for the game developers. The Group has determined that it has no additional performance obligation to the developers or game players upon the players completion of the corresponding in-game purchase. Therefore, the Group has determined that it is not the principal in the transaction and accordingly, revenues derived from the sale of in-game currencies are recorded net of remittances to game developers and commission fees made to third-party application stores and other payment channels. Revenue is further recognized at the end of the estimated consumption date by individual game (i.e., the estimated date in-game currencies are consumed within the game), which is typically within a short period of time ranging from two to three days after the purchase of the in-game currencies. Self-developed mobile game In February 2015, the Group launched one self-developed game on its platform and started to generate revenues by in-game sales of virtual items. The Group has determined that it has a single performance obligation to the players who purchased the virtual items to gain an enhanced game-playing experience over the playing period of the paying players. Accordingly, the Group recognizes revenues ratably over the estimated average period of player relationship starting from the point in time when the players purchase the virtual items and once all other revenue recognition criteria are met. The Group operated eight and four self-developed mobile games in 2017 and 2018, respectively. The estimated periods of the player relationship ranged from 56 to 79 days as of December 31, 2017, and was 77 days as of December 31, 2018, respectively. The Group has determined that it is the principal in fulfilling all obligations related to the mobile game operations for self-developed games. Accordingly, revenues are recognized on a gross basis. Commission fees paid to third-party application stores and other payment channels are recorded as cost of revenues.
Revenues from other services in the year ended December 31, 2018 mainly consisted of revenues generated from advertisement resulting from the broadcasting of one television program produced by the Group. During the year ended December 31, 2018, the Group signed an agreement with a television station, under which the Group is responsible for the production of the television program content, which was completed by December 31, 2018. The television station was responsible for providing advertising and marketing solutions to customers in addition to broadcasting the television program content. Revenue generated from the above is in the form of the advertising fees, shared between the television station and the Group based on a pre-determined percentage stated in the agreement. The Group determined that its television content production service represented one performance obligation. The broadcasting of the content was completed in the year ended December 31, 2018 and the revenue was recognized ratably during the period when the content was broadcasted on the television station. |

| Practical expedients and exemptions | Practical expedients and exemptions The Group’s contracts have an original duration of one year or less. Accordingly, the Group does not disclose the value of unsatisfied performance obligations. Additionally, the Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling and marketing expenses. |

| Contract balances | Contract balances Contract balances include accounts receivable and deferred revenue. Accounts receivable represent cash due from third-party application stores and other payment channels as well as from advertising customers and are recorded when the right to consideration is unconditional. The allowance for doubtful accounts reflects the best estimate of probable losses inherent to the account receivable balance. The Group recorded no impairment charges related to contract assets in the period. Deferred revenue primarily includes cash received from paying users related to the Group’s live video service and value-added service as well as cash received from the Group’s advertising customer. Deferred revenue is recognized as revenue over the estimated service period or when all of the revenue recognition criteria have been met. Revenue recognized in 2018 that was included in the deferred revenue balance as of January 1, 2018 was RMB 422,028. |

| Cost of revenues | Cost of revenues Cost of revenues consist of expenditures incurred in the generation of the Group’s revenues, including but not limited to revenue sharing with the broadcasters and talent agencies resulting from the sale of virtual items, production cost in connection the television content, bandwidth costs, commission fee paid to third-party application stores and other payment channels except for those paid related to licensed mobile games which are recorded net of revenue, salaries and benefits paid to employee, depreciation and amortization. These costs are expensed as incurred except for the direct and incremental platform commission fees to third-party application stores and other payment channels and production cost in connection with the television content which are deferred in “Prepaid expenses and other current assets” on the consolidated balance sheets. Such deferred costs are recognized in the consolidated statements of operations in “Cost of revenues” in the period in which the related revenues are recognized. |

| Government subsidies | Government subsidies For the government subsidies not subject to further performance obligations or future returns, the Group records the amounts as other income when received from local government authority. Whereas for the government subsidies with certain future performance obligations, the Group recognizes those as liabilities when received until the performances obligations have been met at which time, those are recognized as other income. Government subsidies recorded as other income amounted to RMB2,000, RMB141,688 and RMB223,995 for the years ended December 31, 2016, 2017 and 2018. |

| Research and development expenses | Research and development expenses Research and development expenses primarily consist of (i) salaries and benefits for research and development personnel, and (ii) technological service fee, office rental and depreciation expenses associated with the research and development activities. The Group’s research and development activities primarily consist of the research and development of new features for its mobile platform and its self-developed mobile games. The Group has expensed all research and development expenses when incurred. |

| Value added taxes ("VAT") | Value added taxes (“VAT”) Entities that are VAT general taxpayers are allowed to offset qualified input VAT paid to suppliers against their output VAT liabilities. Net VAT balance between input VAT and output VAT is recorded in accrued expenses and other current liabilities on the consolidated balance sheets. VAT is also reported as a deduction to revenue when incurred and amounted to RMB367,635, RMB812,249 and RMB1,136,034 for the years ended December 31, 2016, 2017 and 2018, respectively. |

| Income taxes | Income taxes Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized when temporary differences exist between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. Net operating loss carry forwards and credits are applied using enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that a portion of or all of the deferred tax assets will not be realized. The impact of an uncertain income tax position on the income tax return is recognized at the largest amount that is more-likely than- not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes. |

| Foreign currency translation and change in reporting currency | Foreign currency translation and change in reporting currency The reporting currency of the Company is the Renminbi (“RMB”). The functional currency of the Company is the US dollar (“US$”). The Company’s operations are principally conducted through the subsidiaries, its VIEs and VIEs’ subsidiaries located in the PRC where the local currency is the functional currency. Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency at the rates of exchange in place at the balance sheet date. Transactions in currencies other than the functional currency during the year are converted into the functional currency at the applicable rates of exchange prevailing when the transactions occurred. Transaction gains and losses are recognized in the consolidated statement of operations. Assets and liabilities of the Group companies are translated from their respective functional currencies to the reporting currency at the exchange rates at the balance sheet dates, equity accounts are translated at historical exchange rates and revenues and expenses are translated at the average exchange rates in effect during the reporting period. The resulting foreign currency translation adjustment are recorded in other comprehensive income (loss). Starting from the fourth quarter of 2018, the Group changed its reporting currency from US$ to RMB, to reduce the impact of increased volatility of the RMB to US$ exchange rate on the Group’s reported operating results. The aligning of the reporting currency with the underlying operations will better depict the Group’s results of operations for each period. The related financial statements prior to October 1, 2018 have been recasted to RMB as if the financial statements originally had been presented in RMB since the earliest periods presented. The change in reporting currency resulted in cumulative foreign currency translation adjustment to the Group’s comprehensive income amounted to a gain of RMB175,963, a loss of RMB155,368 and a gain of RMB198,654 for the years ended December 31, 2016, 2017 and 2018, respectively. Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the noon buying rate of US$1.00 = RMB6.8755 on the last trading day of 2018 (December 31, 2018) representing the certificated exchange rate published by the Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at such rate, or at any other rates. |

| Share-based compensation | Share-based compensation Share-based payment transactions with employees and executives are measured based on the grant date fair value of the equity instrument issued and recognized as compensation expense net of a forfeiture rate on a straight-line basis, over the requisite service period, with a corresponding impact reflected in additional paid-in capital. Share-based compensation with cash settlement features is classified as liabilities. The percentage of the fair value that is accrued as compensation cost at the end of each period is based on the percentage of the requisite service that has been rendered at that date. Changes in fair value of the liability classified award that occur during the requisite service period is recognized as compensation cost over that period. These awards typically vest over a period of four years, but may fully vest due to the achievement of certain performance conditions. Share-based compensation expense is recognized on an accelerated basis if it is probable that the performance conditions will be achieved during the vesting period. Share awards issued to consultants are measured at fair value at the earlier of the commitment date or the date the services are completed and recognized over the period the services are provided. The estimate of forfeiture rate is adjusted over the requisite service period to the extent that actual forfeiture rate differs, or is expected to differ, from such estimates. Changes in estimated forfeiture rate is recognized through a cumulative catch-up adjustment in the period of change. Changes in the terms or conditions of share options are accounted as a modification. The Group calculates the excess of the fair value of the modified option over the fair value of the original option immediately before the modification, measured based on the share price and other pertinent factors at the modification date. For vested options, the Group recognizes incremental compensation cost in the period that the modification occurred. For unvested options, the Group recognizes, over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date. |

| Earnings per share | Earnings per share Basic earnings per ordinary share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period. The Group determined that the nonvested restricted shares are participating securities as the holders of the nonvested restricted shares have a nonforfeitable right to receive dividends with all ordinary shares but the nonvested restricted shares do not have a contractual obligation to fund or otherwise absorb the Group’s losses. Accordingly, the Group uses the two-class method whereby undistributed net income is allocated on a pro rata basis to the ordinary shares and nonvested restricted shares to the extent that each class may share the income for the period; whereas the undistributed net loss for the period is allocated to ordinary shares only because the nonvested restricted shares are not contractually obligated to share the loss. Diluted earnings per ordinary share reflect the potential dilution that could occur if securities were exercised or converted into ordinary shares. The Group had share options, restricted share units and convertible senior notes, which could potentially dilute basic earnings per share in the future. To calculate the number of shares for diluted earnings per ordinary share, the effect of the share options and restricted share units is computed using the treasury stock method, and the effect of the convertible senior notes is computed using the as-if-converted method. |

| Recent accounting pronouncements adopted | Recent accounting pronouncements adopted On January 1, 2018, the Company adopted Topic 606. Under the standard, revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company applied the five step method outlined in Topic 606 to all revenue streams and elected to adopt the standard using the modified retrospective method. Refer to Note 2, Revenue recognition for further details. In January 2016, the FASB issued a new pronouncement ASU 2016-01 Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU also provides a new measurement alternative for equity investments that do not have readily determinable fair values and do not qualify for the net asset value practical expedient. The ASU requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. ASU 2016-01 was further amended in February 2018 by ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. This update was issued to clarify certain narrow aspects of the guidance concerning the recognition of financial assets and liabilities established in ASU 2016-01. This includes an amendment to clarify that an entity measuring an equity security using the measurement alternative may change its measurement approach to a fair valuation method in accordance with Topic 820, Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issued. ASU 2016-01 and ASU 2018-03 are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance permits early adoption for certain provisions. Adoption of the amendment must be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for amendments related to equity instruments that do not have readily determinable fair values which should be applied prospectively. The Group adopted ASU 2016-01 and ASU 2018-03 under the modified retrospective method in the fiscal year of 2018. The adoption of 2016-01 and ASU 2018-03 did not have a significant impact on the Company’s consolidated results of operations, financial position or cash flows.
In November 2016, the FASB issued ASU 2016-18: Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update do not provide a definition of restricted cash or restricted cash equivalents. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Group adopted ASU 2016-18 under the retrospective method in the fiscal year of 2018. The adoption of 2016-18 did not have a significant impact on the Company’s cash flows for the years ended December 31, 2016, 2017 and 2018. In January 2017, the FASB issued ASU 2017-01: Business Combinations (Topic 805): Clarifying the Definition of a Business. The Update requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. Early application of the amendments in this update is allowed. The amendments in this Update should be applied prospectively on or after the effective date. No disclosures are required at transition. The Group adopted this guidance on January 1, 2018. The adoption did not have significant impact on the Company’s consolidated results of operations, financial position or cash flows. |

| Recent accounting pronouncements not yet adopted | Recent accounting pronouncements not yet adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. ASU 2016-02 is effective for public business entities for annual reporting periods and interim periods within those years beginning after December 15, 2018. The Group will adopt ASU 2016-02 on January 1, 2019 using the modified retrospective method. The Group will elect the package of practical expedients permitted under the transition guidance, which allows the Group to carry forward the historical lease classification and, the assessment whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard. The Group will also elect the practical expedient not to separate lease and non-lease components for certain classes of underlying assets and the short-term lease exemption for contracts with lease terms of 12 months or less. Certain operating leases related to offices and internet data center (“IDC”) facilities will be subject to ASU 2016-02 and right-of-use assets and lease liabilities will be recognized on the Group’s consolidated balance sheet. The Company currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company’s balance sheet for certain in-scope operating leases. The Company does not expect any material impact on net assets and the consolidated statement of comprehensive income as a result of adopting the new standard. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements.
In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting to simplify the accounting for share-based payments to nonemployees (“ASU 2018-07”) by aligning it with the accounting for share-based payments to employees, with certain exceptions. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date, which may lower their cost and reduce volatility in the income statement. The guidance is effective for public business entities in annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The Group will adopt ASU 2018-07 on January 1, 2019 using grant date fair value to measure equity-classified nonemployee awards. The Group does not expect that the adoption of ASU 2018-07 will have a significant impact on the Group’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Company is currently in the process of evaluating the impact of the adoption of ASU 2018-13 on its consolidated financial statements. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials (“ASU 2019-02”) which improves GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for the Company’s fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Group is in the process of evaluating the impact of adoption of this guidance on its consolidated financial statements. |
