Most of the entities listed above are either holding companies or companies that have no operations. The entities that have substantive operations include: the Multi Group and its subsidiaries and the VIEs or subsidiaries of E-Sun Sky Computer. The Group provides mobile gaming services, sports information services and online spot commodity trading services in the PRC, and online gaming services in Europe. The Group’s principal geographic markets are in the PRC and northern Europe. Information on Variable Interest Entities (“VIEs”) PRC laws and regulations prohibit or restrict foreign ownership of Internet businesses. To comply with these foreign ownership restrictions, the Company operates its websites and provides online lottery purchase services (which has been ceased since March 2015) in the PRC through the VIEs. Prior to December 28, 2013, the Company entered into exclusive business cooperation agreements, power of attorney, equity interest pledge agreements, exclusive option agreements, financial support agreements and supplementary agreements to the exclusive option agreements (previously named as exclusive technical consulting and service agreements, power of attorney, equity pledge agreements, equity interest disposal agreements, financial support agreements, business operation agreements and intellectual properties license agreements prior to June 1, 2011) (the “Contractual Arrangements”), with several entities through E-Sun Sky Computer, which obligates E-Sun Sky Computer to absorb a majority of the expected losses from the activities of these entities’ activities, and entitles E-Sun Sky Computer to receive a majority of residual returns from these entities’ activities. As result of these contractual arrangements, these entities are considered as VIEs of the Company. Through these aforementioned agreements, the Company maintains the ability to approve decisions made by the VIEs, and the ability to acquire the equity interests in the VIEs when permitted by the PRC laws via E-Sun Sky Computer. As a result of the Contractual Arrangements and because the Company has been determined to 1) be the most closely associated with the VIEs as it has the power to direct the activities of the VIEs that most significantly impact their economic performance, and 2) has the obligation to absorb losses and/or the right to receive benefits of the VIEs that could potentially be significant to the VIEs, the Company consolidates the VIEs as required by Accounting Standards Codification (“ASC”) 810 (“ASC 810”), “Consolidation”. On December 28, 2013, the Company agreed to provide unlimited financial support to the VIEs for their operations. In addition, pursuant to the power of attorney agreements entered into among the Company, E-Sun Sky Computer and the nominee shareholders of the VIEs, on December 28, 2013, the nominee shareholders of the VIEs assigned the rights to attend the VIEs’ shareholders' meetings and to vote on all of the matters in the VIEs that require shareholders' approval, which was originally entrusted to E-Sun Sky Computer, to the Company. As a result of the assignment of power of attorney from E- Sun Sky Computer to the Company and the provision of unlimited financial support from the Company to the VIEs, the Company has been determined to be most closely associated with the VIEs within the group of related parties and replaced E-Sun Sky Computer as the primary beneficiary of the VIEs on December 28, 2013. On January 10, 2017, as a result of the acquisition of Qufan Internet Technology Inc., the Company also entered into the contractual arrangements with Shenzhen Qufan Network Technology Co., Ltd., through Qufan Information Technology (Shenzhen) Co., Ltd, which obligates Qufan Information Technology (Shenzhen) Co., Ltd to absorb a majority of the expected losses from the activities of Shenzhen Qufan Network Technology Co., and entitles Qufan Information Technology(Shenzhen) Co., Ltd to receive a majority of residual returns from Shenzhen Qufan Network Technology Co., Ltd. The Company has disposed of Qufan Internet Technology Inc., together with its subsidiaries and related VIEs in February 2018. In February 2018, the above contractual arrangements between Qufan Information Technology (Shenzhen) Co., Ltd and Shenzhen Qufan Network Technology Co., Ltd were terminated. The carrying amounts of the assets, liabilities, the results of operations and cash flows of all of these VIEs included in the Group’s consolidated balance sheets, statements of comprehensive loss and statements of cash flows are as follows: As of As of As of As of December December December December 31, 2017 31, 2018 31, 2019 31, 2019 RMB RMB RMB US$ ASSETS Current assets: Cash and cash equivalents 85,161 123,482 194,914 27,998 Restricted cash 1,237 1,253 1,539 221 Time Deposit — — 100 14 Amounts due from intergroup companies 2,555 2,627 992 143 Amounts due from a related party — — 10,401 1,494 Prepayments and other current assets 33,692 28,934 14,608 2,098 Current assets for discontinued operations 40,193 — — — Total current assets 162,838 156,296 222,554 31,968 Non-current assets: Property and equipment, net 99,138 67,349 44,354 6,371 Intangible assets, net 1,734 1,623 1,636 235 Deposits 4,248 4,484 5,117 735 Long-term investments 53,044 51,332 34,417 4,944 Right-of-use assets — — 33,633 4,831 Other non-current assets 6,296 3,563 1,887 271 Non-current assets for discontinued operations 179,932 — — — Total non-current assets 344,392 128,351 121,044 17,387 TOTAL ASSETS 507,230 284,647 343,598 49,355 LIABILITIES Current liabilities: Amounts due to intergroup companies 71,168 209,384 367,368 52,769 Accrued payroll and welfare payable 9,875 7,854 4,830 694 Accrued expenses and other current liabilities 51,658 54,200 36,087 5,183 Operating lease liabilities - current — — 13,698 1,968 Income tax payable 615 1,313 1,525 219 Current liabilities for discontinued operations 15,626 — — — Total current liabilities 148,942 272,751 423,508 60,833 Non-current liabilities: Long-term payables 27,673 4,196 2,965 426 Operating lease liabilities - non-current — — 31,675 4,550 Non-current liabilities for discontinued operations 12,721 — — — Total non-current liabilities 40,394 4,196 34,640 4,976 TOTAL LIABILITIES 189,336 276,947 458,148 65,809 For the years ended December 31, 2017 2018 2019 2019 RMB RMB RMB US$ Net revenues for continuing operations 22,489 20,578 4,093 588 Net revenues for discontinued operations 59,465 7,398 — — Net loss for continuing operations (138,991) (103,383) (135,816) (19,509) Net income for discontinued operations 14,957 2,183 — — For the years ended December 31, 2017 2018 2019 2019 RMB RMB RMB US$ Net cash used in operating activities (162,328) (93,142) (80,729) (11,596) Net cash provided by (used in) investing activities 6,350 11,164 (254) (36) Net cash provided by financing activities — 104,453 152,701 21,934 There was no pledge or collateralization of the VIEs’ assets.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation and use of estimates The accompanying consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s consolidated financial statements include, but are not limited to, revenue recognition, allowance for doubtful accounts, useful lives of property and equipment, impairment of long-lived assets, long-term investments and goodwill, the purchase price allocation and fair value of non-controlling interests with respect to business combinations, realization of deferred tax assets, uncertain income tax positions and share-based compensation. Actual results could materially differ from those estimates. Principles of consolidation The consolidated financial statements of the Group include the financial statements of the Company, its subsidiaries and VIEs in which it has a controlling financial interest. The results of the subsidiaries are consolidated from the date on which the Group obtained control and continue to be consolidated until the date that such control ceases. A controlling financial interest is typically determined when a company holds a majority of the voting equity interest in an entity. Furthermore, if the Company demonstrates that it has ability to control the VIEs through its rights to all the residual benefits of the VIEs and its obligation to fund losses of the VIEs then the entity is consolidated. All significant intercompany balances and transactions among the Company, its subsidiaries and VIEs have been eliminated on consolidation. Reclassification Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on net earnings and financial position. Convenience translation Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the noon buying rate of US$1.00 to RMB6.9618 on December 31, 2019 in the city of New York for wire transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York. No representation is made that the RMB amounts could have been, or could be, converted into US$ at such rate. Foreign currency translation The functional currency of the Company, BVI, 500wan HK, 500.com USA and 500.com JP is the US$. The functional currency of the Multi Group and its subsidiaries is EUR. E-Sun Sky Computer with its VIEs determined their functional currencies to be the RMB, which is their respective local currencies based on the criteria of ASC 830, “ Foreign Currency Matters” . The Group uses the monthly average exchange rate for the year and the spot exchange rate at the balance sheet date to translate the operating results and financial position, respectively. Translation differences are recorded in accumulated other comprehensive income as a component of shareholders’ equity. The Group uses the RMB as its reporting currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing on the transaction dates. Exchange gains and losses resulting from foreign currency transactions are included in the consolidated statements of comprehensive loss. Business combinations and noncontrolling interests The Group accounts for its business combinations using the purchase method of accounting in accordance with ASC 805 (“ASC 805”), “ Business Combinations” . The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Group acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over, (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings. The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period. For the Company's majority-owned subsidiaries and VIEs, noncontrolling interests are recognized to reflect the portion of their equity which is not attributable, directly or indirectly, to the Group. “Net loss” on the consolidated statements of comprehensive loss include the “net loss attributable to noncontrolling interests”. The cumulative results of operations attributable to noncontrolling interests are also recorded as noncontrolling interests in the Company's consolidated balance sheets. Cash and cash equivalents Cash and cash equivalents represent cash on hand and time deposits, which have original maturities of three months or less when purchased and which are unrestricted as to withdrawal and use. In addition, highly liquid investments which have original maturities of three months or less when purchased are classified as cash equivalents. Restricted cash Restricted cash represents cash held by banks which were granted by the government and designated only for the purchase of fixed assets for certain approved projects and deposits in merchant bank where withdrawals are currently restricted. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts presented in the statement of cash flows. The Group adopted the new standard effective January 1, 2018, using the retrospective transition method. All restricted cash was presented on the face of the consolidated balance sheet as “Restricted cash.” Time deposits Time deposits represent deposits in commercial banks with original maturities of greater than three months but less than a year. Interest income from time deposits is included in the consolidated statements of comprehensive loss. Short-term investments Short-term investments of the Group are comprised of an investment in targeted asset management plan with fixed rate. The Group accounts for all highly liquid investments with original maturities of greater than three months, but less than 12 months, in accordance with ASC 320-10, “Investments—Debt and Equity Securities”, which are classified as short-term investments. Dividend and interest income, including amortization of the premium and discount arising at acquisition for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short­term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. The Group evaluates whether a decline in fair value below the amortized cost basis is other­than­temporary in accordance with ASC 320. Other­than­temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. Allowance for doubtful accounts Receivables are carried at original invoiced amount less an allowance for doubtful accounts when collection of the amount is no longer probable. In evaluating the collectability of receivable balances, the Group considers factors such as customer circumstances or age of the receivable. Receivables are written off after all collection efforts have ceased. Collateral is not typically required, nor is interest charged on receivables. Property and equipment, net Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets, as follows: Category Estimated Useful Life Estimated Residual Electronics and office equipment 3-5 years 5 % Motor vehicles 5-10 years 2-5 % Leasehold improvements Shorter of lease term or the estimated useful lives of the assets — Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterment that extend the useful lives of property and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidated statements of comprehensive loss. Intangible assets Intangible assets represent computer software, internet domain name, licensing agreement, and intangible assets arising from business combination. Computer software, internet domain name and licensing agreement purchased from third parties are initially recorded at cost and amortized on a straight line basis over their estimated useful lives of the respective assets. The Group performs valuation of the intangible assets arising from business combination to determine the relative fair value to be assigned to each asset acquired. The acquired intangible assets are recognized and measured at fair value and are expensed or amortized using the straight-line approach over the estimated useful life of the assets. Estimated useful lives of the respective assets are set out as follows: Category Estimated Useful Life Computer software 3-10 years Internet domain name 10 years Licensing agreement Agreement term Intangible assets arising from business combination Licenses and brand name 10 years Mobile applications and software 5 years Goodwill The Group assesses goodwill for impairment in accordance with ASC 350-20 (“ASC 350-20”), “ Intangibles–Goodwill and Other: Goodwill ”, which requires that goodwill to be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20. Prior to the early adoption of ASU 2017-04, “ Simplifying the Test for Goodwill Impairment ”, on January 1, 2019, the Group has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20. If the Group believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, the two-step quantitative impairment test described above is required. Otherwise, no further testing is required. In the qualitative assessment, the Group considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. In performing the two-step quantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Group is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Group must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss. In 2018 and 2017, the Group performed qualitative assessments for the reporting units. Based on the requirements of ASC 350-20, the Group evaluated all relevant factors, weighed all factors in their entirety and concluded that the fair value was greater than the carrying amount of the newly acquired entities, and further impairment testing on goodwill was unnecessary as of December 31, 2018 and 2017. In January 2017, the FASB issued Accounting Standards Update No. 2017-04(“ASU 2017-04”), “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This standard is effective for public business entities in fiscal years beginning after December 15, 2019. Early adoption is permitted. The Group early adopted the ASU 2017-04 on January 1,2019. As triggered by TMG’s temporary suspension of its operations in Sweden since January 2020, the Group performed qualitative and quantitative assessment in accordance with ASU 2017-04 and recognized an impairment loss of RMB129,752 (US$18,638) for goodwill arising from acquisition of TMG as of December 31, 2019. Impairment of long-lived assets other than goodwill The Group evaluates its long-lived assets or asset group, including property and equipment, intangible assets and right-of-use assets, with finite lives for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be fully recoverable. When these events occur, the Group evaluates the impairment by comparing the carrying amount of the assets to future undiscounted 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 excess of the carrying amount of the asset group over its fair value. The Group provided an impairment loss of nil, nil and RMB181,845 (US$26,120) for intangible assets arising from acquisition of the Multi Group as of December 31, 2017, 2018 and 2019, respectively. Long-term investments The Group’s long­term investments consist of equity investments with and equity investments without readily determinable fair value and equity method investments. Prior to adopting ASC Topic 321, Investments Equity Securities (“ASC 321”) on January 1, 2018, the Group carries at cost its investments in investees that do not have readily determinable fair value and over which the Group does not have significant influence, in accordance with ASC Subtopic 325 ­20, Investments ­Other: Cost Method Investments. In accordance with ASC 325, “ Investments-Other” , for investments in an investee over which the Group does not have significant influence and which do not have readily determinable fair value, the Group carries the investment at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings that exceed the Group’s share of earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on 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, cash flow forecasts and financing needs. 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 investment. Pursuant to ASC 321, equity investments, except for those accounted for under the equity method, those that result in consolidation of the investee and certain other investments, are measured at fair value, and any changes in fair value are recognized in earnings. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) to estimate fair value using the net asset value per share (or its equivalent) of the investment, the Group 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. Equity securities with readily determinable fair value are measured at fair values, and any changes in fair value are recognized in earnings. For those equity investments that the Group elects to use the measurement alternative, the Group 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 entity 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 entity has to recognize an impairment loss in net income equal to the difference between the carrying value and fair value. As the Group’s investments in investees do not have readily determinable fair value and over which the Group does not have significant influence, when adopting ASC 321 on January 1, 2018, the Group 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. There was no effect on the Company’s consolidated financial statements subsequent to the adoption of ASC 321. Investments in entities in which the Group can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC 323 (“ASC 323”), “Investments-Equity Method and Joint Ventures”. Under the equity method, the Group initially records its investment at cost and the difference between the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The equity method goodwill is not subsequently amortized and is not tested for impairment under ASC 350. The Group subsequently adjusts the carrying amount of the investment to recognize the Group’s proportionate share of each equity investee’s net income or loss into earnings after the date of investment. The Group will discontinue applying the equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero. Under the conditions that the Group is not required to advance additional funds to an investee and the equity-method investment in ordinary shares is reduced to zero, if further investments are made that have a higher liquidation preference than ordinary shares, the Group would recognize the loss based on its percentage of the investment with the same liquidation preference, and the loss would be applied to those investments of a lower liquidation preference first before being further applied to the investments of a higher liquidation preference. The Group evaluates the equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Group when determining whether an investment has been other­than­temporarily­impaired, includes, but not limited to, the length of the time and the extent to which the market value has been less than cost, the financial performance and near­term prospect of the investee, and the Group's intent and ability to retain the investment until the recovery of its cost. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. According to the above testing, impairment losses of RMB28,781, RMB149,896 and RMB22,353 (US$3,211) for the long-term investments were recognized during the years of 2017, 2018 and 2019, respectively. Investments in limited partnerships greater than 5% are considered more than minor and accounted for using the equity method, unless it is readily apparent that the Group has virtually no influence over the partnership’s financial and operating policies. Fair value measurements Financial instruments primarily include cash and cash equivalents, restricted cash, time deposits, investment in targeted asset management plan with fixed rate (Note 6), prepayments and other receivables, equity security without readily determinable fair values, equity method investments, and accrued expense and other current liabilities. The Group carries the investment under the measurement alternative method and equity method on other-than-temporary basis. The carrying values of other financial instruments, approximate their fair values due to their short-term maturities. The Group's non-financial assets, including intangible assets, goodwill and fixed assets are measured at fair value when an impairment charge is recognized. The Group applies ASC 820 (“ASC 820”), “Fair Value Measurements and Disclosures ”. ASC 820 defines fair value, establishes a framework for measuring fair value and requires disclosures to be provided on fair value measurement. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1— Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2— Include other inputs that are directly or indirectly observable in the marketplace. Level 3— Unobservable inputs which are supported by little or no market activity. ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach, and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. Related party transactions A related party is generally defined as (i) any person holds 10% or more of the Company’s securities and their immediate families (ii) the Company’s management, (iii) someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities. Transactions involving related parties cannot be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free market dealings may not exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. It is not, however, practical to determine the fair value of amounts due from/to related parties due to their related party nature. Revenue recognition The Group’s revenues were derived principally from online lottery purchase services before voluntary suspension of this service since April 2015. During the voluntary suspension period, the Group diversified its revenue streams, and derived revenues from mobile gaming services, sports information services, online spot commodity trading services and online gaming services. The Group adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the years ended December 31, 2019 and 2018 were presented under ASC 606, and revenues for the year ended December 31, 2017 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. Revenue is recognized when control of promised goods or services is transferred to the Group's customers in an amount of consideration to which the Group expects to be entitled to in exchange for those goods or services. The Group follows the five steps approach for revenue recognition under Topic 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the Group satisfies a performance obligation. The Group set up an implementation schedule and analyzed each of the Group’s revenue streams in accordance with ASC 606 to determine the impact on the Group’s consolidated financial statements. After the analyzation, the Group concluded that there was no substantial impact on the Group’s consolidated financial statements upon the adoption of ASC 606. The primary sources of the Group’s revenues are as follows: Online lottery purchase services The Group earns service income for online lottery purchase services and revenues are generated from processing lottery purchase orders from end users (“Service Fee”). The Group receives purchase orders from end users through its online platforms, which include website and mobile applications, and processes the orders with the lottery administration centers. Service Fee is received from the lottery administration centers based on the pre-determined service fee rate and the total amount of the processed orders. Pursuant to ASC 605‑45, “ Principal Agent Considerations ”, the Group records Service Fee on a net basis because the Group is not the primary obligor in the arrangement, but acts as an agent in providing such purchase services. The Group did not generate any revenue from this service since April 2015 when the Group voluntarily suspended the online lottery purchase services due to the change of related government regulation in the PRC. It is uncertain when the services will be resumed. Contingent service fee The Group was also entitled to receive additional Service Fee from lottery administration centers when the total amounts of purchase orders reach an agreed threshold (“Contingent Service Fee”). As the Group is the agent in providing lottery purchase services, any Contingent Service Fee received is recorded as net revenue when the agreed thresholds are reached. Once the Group reaches the agreed thresholds, the Contingent Service Fee is then fixed and not subject to any adjustments. As a result of the voluntarily suspension of the online lottery purchase services mentioned above, the Group did not generate any revenue from this source either since April 2015, and it is uncertain when the Group will be able to generate this fee again in the future. The Super VIP incentive Certain qualified end users (“Super VIP”) are entitled to receive incentives from the Group based on actual purchase amount of each transaction. As the Group does not receive an additional service or benefit from the Super VIP other than service fee earned from lottery administration centers by the Group from the transaction, the incentives are recognized as a reduction of revenue at each year end in accordance with ASC 605‑50, “ Customer Payments and Incentives” . The Group voluntarily suspended the online lottery purchase services due to the change of related government regulation in the PRC, and it is uncertain when the Group will be subject to this fee again in the future. Lottery pool purchase service Lottery pools involve individual end users purchasing a share in a pooled lottery outcome or group of outcomes with other end users. Through the lottery pool purchase service, an end user, an initiator, starts a lottery pool by specifying a range of parameters, such as the lottery portfolio, total purchase amount and payout ratio. The initiator is required to commit a minimum initial purchase amount when they initiate a pool, usually a certain percentage of the total purchase amount. Other end users then join the pool by agreeing to the parameters set by the initiator and committing on the purchase amount. When the total purchase amount as specified by the initiator is reached, the pooled lottery purchase order will be delivered in the manner specified by the initiator. When the actual purchase amount does not reach the total purchase amount as specified by the initiator but reaches a certain percentage of total purchase amount before the lottery pool purchase deadline, the Group contributes the remaining outstanding purchase amount (i.e., residual amount of lottery pool) to complete the lottery pool transaction. If the tickets win prizes from the lottery, the Group distributes the cash prizes to the end users based on the predetermined payout ratio, and the residual amount after distribution is retained by the Group. Since the Group contributes the residual amount of lottery pool to earn Service Fee from the purchase made by the lottery pool and does not provide any service to the lottery administration centers, the residual amount of lottery pool contributed by the Group paid to the lottery administration centers is recognized as a reduction of revenue. The residual amount of the lottery pool retained by the Group after distribution of the prizes are presented as “other operating income”, and recognized upon the announcement of lottery results, as the Group’s principal activity is to provide lottery purchase services to end users. The Group did not generate any revenue from this source either since April 2015, and it is uncertain when the Group will be able to generate this fee again in the future. Mobile gaming services The Group provides mobile gaming services through its designated mobile applications Quiz, Night of Texas Hold’em Poker and Paiyou for Texas Hold’em Poker, and derives revenues from in-game virtual tokens and other virtual items in its game development operations. Once the users purchase virtual tokens or other virtual items through the Group’s own charging system, the Group has an implied obligation to provide the services which enable the virtual tokens or other virtual items to be displayed or used in the games. Thus, the Group initially records th

CONCENTRATION OF RISKS
CONCENTRATION OF RISKS	3. CONCENTRATION OF RISKS Concentration of credit risk Assets that potentially subject the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, and time deposits. As of December 31, 2019, substantially all of the Group’s cash and cash equivalents and time deposits were deposited in financial institutions located in the PRC, Hong Kong and Malta, which management believes are of high credit quality. Certain risks and uncertainties The Group acquired the Multi Group in July 2017, the operations of which are dependent on its continued licensing by the Nordic countries gaming regulatory bodies such as the Curacao e-Gaming license, the remote gambling licenses from Malta, the remote operating licenses from the UK, the remote bookmaker’s license from Ireland and the license from Sweden. the Multi Group ceased its operations in Ireland and the United Kingdom on July 1, 2019 and September 30, 2019, respectively, and temporarily suspended its operations in Sweden since January 2020 as TMG did not complete the renewal of its Swedish online gambling license before it expired at the end of 2019, After submitting all the application materials and maintaining close communication with Sweden's e-Gaming regulatory authority, TMG completed the renewal process and resumed its operations in Sweden in September 2020. The loss of a license could have a material adverse effect on future results of its operations. The Group is dependent on the PRC and European markets for a significant number of its patrons and revenues. If economic conditions in these areas deteriorate or additional gaming licenses are awarded to other competitors, the Group’s results of operations could be adversely affected. The Group is also dependent on the PRC economy in general, and any deterioration in the national economic, energy, credit and capital markets could have a material adverse effect on future results of operations. The Group is dependent upon a stable gaming and admission tax structure in the locations in which it operates. Any change in the tax structure could have a material adverse effect on future results of operations. The Group‘s reporting currency RMB, which is not freely convertible into foreign currencies. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts. Additionally, the value of the RMB is subject to changes in central government policies and international economic and political developments affecting supply and demand in the PRC foreign exchange trading system market. Current vulnerability due to change of regulations or policies The Group’s operations may be adversely affected by significant political, economic and social uncertainties in the PRC. Although the PRC government has been pursuing economic reform policies for more than 30 years, no assurance can be given that the PRC government will continue to pursue such policies or that such policies may not be significantly altered, especially in the event of a change in leadership, social or political disruption or unforeseen circumstances affecting the PRC’s political, economic and social conditions. There is also no guarantee that the PRC government’s pursuit of economic reforms will be consistent or effective. In October 2012, the Group was notified by China Sports Lottery Administration Center that the Group was one of the two entities that had been approved by the Ministry of Finance (“MOF”) to conduct online sales of sports lottery products in PRC on behalf of China Sports Lottery Administration Center. On January 15, 2015, the MOF, the Ministry of Civil Affairs and the General Administration of Sports of the People’s Republic of China jointly promulgated the Notice on Issues related to the Self-Inspection and Self-Remedy of Unauthorized Online Lottery Sales (the “ Self-Inspection Notice”) , as a further step to regulate the lottery market in PRC and sanction unauthorized online lottery sales. On February 28, 2015, all sports lottery administration centers temporarily suspended online purchase orders for lottery products in response to the Self-Inspection Notice. On April 3, 2015, eight competent government authorities, namely, the MOF, the Ministry of Public Security, the State Administration for Industry and Commerce, the Ministry of Industry and Information Technology, Ministry of Civil Affairs, People’s Bank of China, the General Administration of Sports of China and China Banking Regulatory Commission, jointly released a public bulletin with regard to online lottery sales in China, or Bulletin 18. Bulletin 18 mandates, among other things, that (i) all institutions, online entities, or individuals which provide unauthorized online lottery sales services, either directly or through agents, shall immediately cease such services and all provincial governmental authorities of finance, civil affairs and sports shall investigate and sanction unauthorized online lottery sales in their respective jurisdictions according to relevant laws and regulations; and (ii) lottery issuance authorities that plan to sell lottery products online are required to obtain a consent from the Ministry of Civil Affairs or the General Administration of Sports of China in order to submit an application for written approval by the MOF. Although the Group is one of the two entities that had been approved by the MOF to conduct online sales of sports lottery products in PRC on behalf of China Sports Lottery Administration Center, the Group decided to voluntarily and temporarily suspend all of its lottery sales services on April 4, 2015. As of December 31, 2019, the online lottery sales business is still not resumed.

From February 9, 2018, the Company no longer retained any financial interest over Qufan and accordingly deconsolidated the Qufan’s financial statements from the Group’s consolidated financial statements. The disposal of Qufan represented a strategic shift and has a major effect on the Group’s result of operations. Accordingly, assets, liabilities, revenues, expenses and cash flows related to Qufan have been reclassified in the consolidated financial statements as discontinued operations for the years ended December 31,2017 and 2018. On February 9, 2018, the Company calculated a gain resulting from such disposition as follows: As of February 9, 2018 RMB Consideration 121,964 Cash and cash equivalents 41,699 Short-term investments 20,000 Prepayments and other receivables 6,428 Property and equipment, net 1,490 Intangible assets, net 45,847 Goodwill 130,613 Long-term investments 2,000 Other non-current assets 14 Accrued payroll and welfare payable (5,104) Accrued expenses and other current liabilities (756) Income tax payable (4,927) Deferred revenue (5,527) Deferred tax liabilities (12,554) Net assets of Qufan 219,223 Equity interest percentage 51 % Less: Net assets of Qufan attributable to the Company 111,804 Gain on disposal of Qufan 10,160 The assets and liabilities for discontinued operations related to Qufan comprised the following items as of December 31, 2017: As of December 31, 2017 RMB Current assets for discontinued operations Cash and cash equivalents 41,858 Short-term investments 20,000 Prepayments and other receivables 5,344 Total 67,202 Non-current assets for discontinued operations Property and equipment, net 1,489 Intangible assets, net 47,824 Goodwill 130,613 Long-term investments — Other non-current assets 16 Total 179,942 Current liabilities for discontinued operations Accrued payroll and welfare payable (4,828) Accrued expenses and other current liabilities (6,103) Income tax payable (4,695) Total (15,626) Non-current liabilities for discontinued operations Deferred tax liabilities (12,721) Total (12,721) The condensed cash flows of Qufan were as follows for the years ended December 31, 2017 and 2018: For the years ended December 31, 2017 2018* RMB RMB Net cash provided by operating activities 36,782 839 Net cash used in investing activities (22,000) — Net cash provided by financing activities 27,500 — Effect of foreign exchange on cash (1,021) (998) The operating results from discontinued operations included in the Group’s consolidated statements of comprehensive loss were as follows for the years ended December 31, 2017 and 2018: For the years ended December 31, 2017 2018* RMB RMB Major classes of line items constituting pretax profit of discontinued operations Net revenues 59,465 7,398 Cost of services (15,613) (1,885) Sales and marketing (13,682) (1,938) General and administrative (3,977) (443) Service development expenses (9,749) (688) Other income that are not major 542 77 Income from discontinued operations, before income tax 16,986 2,521 Income tax expense (1,659) (338) Income from discontinued operations, net of income tax 15,327 2,183 Gain on deconsolidation of the subsidiary, net of income tax — 10,160 Net income from discontinued operations, net of income tax 15,327 12,343 * Included financial results of discontinued operations from January 1, 2018 to February 9, 2018.

(“Shenzhen Qufan”) entered into a share purchase agreement with the shareholder of Beijing Daguo Xiaoxian Culture Media Co., Ltd. (“Daguoxiaoxian”), named Fu Rong, to acquire 70% equity interests of Daguoxiaoxian with the consideration of RMB2.0 million (“Purchase agreement”). Previously, Daguoxiaoxian mainly operates market promotion business and also owns a gaming cooperation agreement (“cooperation agreement”) with Tianjin Zhongqiweiye Sports Development Co., Ltd. By obtaining the cooperation agreement, Daguoxiaoxian is authorized to operate China Competitive Poker Championship, from May 14, 2017 to May 14, 2018, with one-year extension upon the expiration if no objection between both parties. The Group acquired Daguoxiaoxian primarily for the cooperation agreement. The Group has subsequently disposed Shenzhen Qufan together with its subsidiary Daguoxiaoxian in February 2018 due to a change of business strategy. Acquisition of The Multi Group On July 17, 2017 (“the acquisition date”), the Company acquired 93.0% equity interest of the Multi Group (“TMG”) through 500.com Limited for a total consideration of approximately EUR49.8 million. The Multi Group engages in operating Multilotto.com (“Multilotto”) which is considered one of the top online lottery betting and online casino platforms in the Nordic countries where it holds substantial market share. As of July 17, 2017, the Group settled payment of EUR49,754 cash consideration for the acquisition. The Group recognized RMB18,766 of acquisition-related costs that were expensed in 2017. These costs are included in the line item “General and administrative expenses” in the statement of comprehensive loss. The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date. The Group obtained a third-party valuation of certain intangible assets. The calculation of RMB amount was based on the exchange rate of 1.00 EUR to 7.7514 RMB of the acquisition date on July 17, 2017. Amortization Amount Amount Years EUR RMB License 19,400 150,377 10.0 Brand name 11,100 86,041 10.0 Software 900 6,976 5.0 Others 7,116 55,156 Total identifiable assets acquired 38,516 298,550 Deferred tax liabilities (1,164) (9,023) Other current liabilities (1,422) (11,022) Total liabilities assumed (2,586) (20,045) Net identifiable assets acquired 35,930 278,505 Noncontrolling interest # 2,915 22,595 Total consideration 49,754 385,662 Goodwill 16,739 129,752 # In accordance with the acquisition agreement, the Group is obligated to purchase the remaining 7% equity interest of the Multi Group at the option of the non-controlling shareholder, which is outside the control of the Group (upon the occurrence of an event that is not solely within the control of the issuer). As such, the noncontrolling interest relating to this portion of put options was presented as redeemable noncontrolling interest in mezzanine equity and be initially measured at its fair value in accordance with ASC 480‑10‑S99‑3A. The fair value of redeemable noncontrolling interest was initially recorded as the value assessed by the third-party appraiser on the acquisition day. As of the acquisition date, the fair value of the 7% noncontrolling interest in the Multi Group is estimated to be EUR2,915. The fair value of the noncontrolling interest was estimated using the Income Approach. As the Multi Group was a private company, the fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement as defined in ASC 820. The fair value estimates are based on (a) internal rate of return of 16%; (b) a long-term sustainable growth rate of 2%; (c)adjustment of risk premium of 3%; and (d) financial multiples of companies in the same industry as the Multi Group. The redeemable noncontrolling interest was subsequently adjusted by recording ASC 810‑10 attribution based on the earnings or losses of the investment allocable to the noncontrolling interest. On January 1, 2019, the Company received the repurchase notice from the noncontrolling interest shareholder, which requested the Company to repurchase all of the 7% shares at a total amount of EUR3,745. As of December 31, 2018, it is determined that the noncontrolling interest will probably become redeemable and the redemption amount will be higher than the carrying amount after ASC 810‑10 attribution adjustment. The Company subsequently recognized the changes in the redemption value immediately and adjusted the carrying amount of the redeemable noncontrolling interest to equal the redemption amount of EUR3,745 as of December 31, 2018. The excess amount of redemption amount in excess of fair value as of December 31, 2018 was treated as being akin to a dividend (in accordance with footnote 17 of ASC 480‑10‑S99‑3A), which was recorded into Retained earnings (APIC in absence of Retained earnings). For the difference between fair value and the carrying amount after ASC 810‑10 attribution adjustment, it is accounted for as equity transactions and classified this portion into APIC based on the guidance in ASC 480‑10‑S99‑3A. The fair value of redeemable noncontrolling interest was assessed by the third-party appraiser on December 31, 2018. As of December 31, 2018, the fair value of the 7% noncontrolling interest in the Multi Group is estimated to be EUR2,504. The fair value of the noncontrolling interest was estimated using the Income Approach. As the Multi Group was a private company, the fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement as defined in ASC 820. The fair value estimates are based on (a) internal rate of return of 17.5%; (b) a long-term sustainable growth rate of 2%; (c)adjustment of risk premium of 5.5%; and (d) financial multiples of companies in the same industry as the Multi Group. On April 10, 2020, the Company reached a settlement agreement to purchase the 7% equity interest in TMG held by Helmet at a final redemption price of EUR1,900 and the final redemption price was fully paid on April 20, 2020. The Group adjusted the carrying amount of the 7% redeemable noncontrolling interest to the final redemption amount of EUR1,900 as of December 31, 2019. Accordingly, the carrying value of the noncontrolling interest as of December 31, 2017, 2018 and 2019 is stated as follows: EUR RMB US$ Noncontrolling interest-valuation* 2,915 22,595 Total comprehensive loss attributable to noncontrolling interest in 2017 (70) (543) Redeemable noncontrolling interest as of December 31, 2017 2,845 22,052 Total comprehensive loss attributable to noncontrolling interest in 2018 (413) (3,223) Adjustment to redemption value in 2018** 1,313 10,559 Redeemable noncontrolling interest as of December 31, 2018 3,745 29,388 Adjustment to redemption value in 2019*** (1,845) (14,539) (2,088) Redeemable noncontrolling interest as of December 31, 2019 1,900 14,849 2,133 * Noncontrolling interest in EUR was evaluated by third party appraiser as of the acquisition day. The calculation of RMB amount was based on the exchange rate of 1.00 EUR to 7.7514 RMB at the acquisition date. ** Adjustment to redemption value in 2018 including two portions: 1) the excess amount of redemption amount in excess of fair value as of December 31, 2018, 2) the difference between fair value and the carrying amount after ASC 810‑10 attribution adjustment. The fair value as of December 31, 2018 was evaluated by third party appraiser on December 31, 2018. The calculation of RMB amount was based on the exchange rate of 1.00 EUR to 7.8473 RMB on December 31, 2018. *** Adjustment to redemption value in 2019 was adjusted according to settlement agreement to purchase the 7% equity interest in TMG held by Helmet at a final redemption price of EUR1,900. The calculation of RMB amount was based on the exchange rate of 1.00 EUR to 7.8155 RMB on December 31, 2019. Goodwill, which is not tax deductible, is primarily attributable to the excess of the consideration and fair value of noncontrolling interest over the fair value of the net identifiable assets of the acquiree and is related to synergies expected to be achieved from the acquisition. Acquired intangible assets have weighted average economic lives from the date of purchase as follows: License 10.0 years Brand name 10.0 years Software 5.0 years As of December 31, 2019, the fair value of the equity value including goodwill and the acquired intangible assets of the Multi Group that was assessed by the third-party appraiser are estimated to be nil. The fair value of the equity value including goodwill and the acquired intangible assets were estimated using the Income Approach. As the Multi Group was a private company, the fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement as defined in ASC 820. The fair value estimates are based on (a) internal rate of return of 17.5%; (b) a long-term sustainable growth rate of 2%; (c) adjustment of risk premium of 5.5%; and (d) financial multiples of companies in the same industry as the Multi Group. For the difference between fair value and the carrying amount, the Group recognized an impairment loss of RMB129,752 (US$18,638) for goodwill and RMB181,845 (US$26,120) for acquired intangible assets for the year ended December 31, 2019.

The VIEs are required to allocate at least 10% of their after-tax profits to the statutory surplus fund until such fund has reached 50% of their respective registered capital. Appropriation to discretionary surplus is made at the discretion of each individual VIE. The general reserve fund and statutory surplus fund are restricted to set-off against losses, expansion of production and operation and increasing registered capital of the respective company. The staff welfare and bonus fund and statutory public welfare fund are restricted to the capital expenditures for the collective welfare of employees.

For expected volatilities, the Company has made reference to historical volatilities of several comparable companies. The sub-optimal early exercise factor was estimated based on the vesting and contractual terms of the awards and management’s expectation of exercise behavior of the grantees. The risk-free rate for periods within the contractual life of the options is based on market yield of U.S. Treasury Bond in effect at the time of grant. The assumptions used to estimate the fair value of the share options granted are as follows: For the years ended December 31 2017 2018 2019 Expected volatility 54.83 % 54.27%~60.15 % 66.89%~67.67 % Risk-free interest rate 1.20 % 2.26%~2.62 % 1.62%~1.95 % Dividend yield 0.00 % 0.00 % 0.00 % Forfeiture rate 0.00 % 0.00 % 0.00 % Suboptimal early exercise factor 2.2 2.2~2.8 2.2~2.8 The fair value of restricted shares was determined using the market price of the ordinary shares of the Company on the grant date. There were no vested equity share options granted to the employees and directors during the years ended December 31, 2017, 2018 and 2019. The total fair value of the restricted shares granted to the employees and directors during the years ended December 31, 2017, 2018 and 2019 were RMB78,902, RMB48,575 and RMB40,023 (US$5,749), respectively. The exercise price of share options granted to the employees and directors equaled the market price of the ordinary shares on the grant date. No share options were granted during the year ended December 31, 2017, 2018 and 2019. The Company granted restricted shares to employees and directors during the year ended December 31, 2017, 2018 and 2019 with free exercise price. The weighted-average grant-date fair value per restricted shares granted to employees and directors during the year ended December 31, 2017, 2018 and 2019 were US$0.96, US$1.41 and US$0.76, respectively. Total share-based compensation expenses relating to options and restricted shares granted to employees and directors for the years ended December 31, 2017, 2018 and 2019 are included in: For the year ended December 31, 2017 Employees Directors Total Total RMB RMB RMB US$ Cost of services 1,343 — 1,343 206 Sales and marketing 9,228 — 9,228 1,418 General and administrative 61,113 3,089 64,202 9,868 Service development expenses 16,370 — 16,370 2,516 88,054 3,089 91,143 14,008 For the year ended December 31, 2018 Employees Directors Total Total RMB RMB RMB US$ Cost of services 351 — 351 51 Sales and marketing 11,361 — 11,361 1,652 General and administrative 74,227 2,346 76,573 11,137 Service development expenses 20,343 — 20,343 2,959 106,282 2,346 108,628 15,799 For the year ended December 31, 2019 Employees Directors Total Total RMB RMB RMB US$ Cost of services 14 — 14 2 Sales and marketing 7,410 — 7,410 1,064 General and administrative 57,666 506 58,172 8,356 Service development expenses 13,679 — 13,679 1,965 78,769 506 79,275 11,387

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	17. COMMITMENTS AND CONTINGENCIES Uncertain income tax position As of December 31, 2017, 2018 and 2019, the Group has recognized approximately RMB24,298, RMB2,133 and RMB1,920 (US$276), respectively, as an accrual for unrecognized tax position, including related interest and penalties. The final outcome of the tax uncertainty is dependent upon various matters including tax examinations, interpretation of tax laws or expiration of statute of limitation. However, due to the uncertainties associated with the status of examinations, including the protocols of finalizing audits by the relevant tax authorities, there is a high degree of uncertainty regarding the future cash outflows associated with these tax uncertainties. As of December 31, 2017, 2018, and 2019, the Group classified the accrual of RMB24,298, RMB2,133 and RMB1,920 (US$276), respectively, as a long-term payable. Variable interest entity structure In the opinion of management, (i) the ownership structure of the Company and its VIEs are in compliance with existing PRC laws and regulations; (ii) the contractual arrangements with the VIEs and their shareholders are valid and binding, and will not result in any violation of PRC laws or regulations currently in effect; and (iii) the Group’s business operations are in compliance with existing PRC laws and regulations in all material respects. However, there are substantial uncertainties regarding the interpretation and application of current and future PRC laws and regulations. Accordingly, the Company cannot be assured that PRC regulatory authorities will not ultimately take a contrary view to its opinion. If the current ownership structure of the Group and its contractual arrangements with VIEs are found to be in violation of any existing or future PRC laws and regulations, the Group may be required to restructure its ownership structure and operations in the PRC to comply with the changing and new PRC laws and regulations. In the opinion of management, the likelihood of loss in respect of the Group’s current ownership structure or the contractual arrangements with VIEs is remote based on current facts and circumstances. Contractual arrangements among the Company and the VIEs Under applicable PRC tax laws and regulations, arrangements and transactions among related parties may be subject to audit or scrutiny by the PRC tax authorities within ten years after the taxable year when the arrangements or transactions are conducted. The Company could face material and adverse tax consequences if the PRC tax authorities were to determine that the Contractual Arrangements among the Company and the respective VIEs were not entered into on an arm’s-length basis and therefore constituted unfavorable transfer pricing arrangements. Unfavorable transfer pricing arrangements could, among other things, result in an upward adjustment on taxation. In addition, the PRC tax authorities may impose interest on late payments on the Company and the respective VIEs for the adjusted but unpaid taxes. In the opinion of management, the likelihood of such an upward adjustment on taxation and related interest is remote based on current facts and circumstances. Guarantees The Group accounts for guarantees in accordance with ASC topic 460 (“ASC 460”), Guarantees . Accordingly, the Group evaluates its guarantees to determine whether (a) the guarantee is specifically excluded from the scope of ASC 460, (b) the guarantee is subject to ASC 460 disclosure requirements only, but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements at fair value. The memorandum and articles of association of the Company require that the Company indemnify its officers and directors, as well as those who act as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to the Company. The indemnification obligations are more fully described in the memorandum and articles of association. The Company purchases standard directors and officers’ insurance to cover claims or a portion of the claims made against its directors and officers. Since a maximum obligation is not explicitly stated in the Company’s memorandum and articles of association and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated. Historically, the Group has not been required to make payments related to these obligations, and the fair value for these obligations is zero as of December 31, 2017, 2018 and 2019. Indemnity cost There was no indemnity cost occurred in 2017, 2018 and 2019. Legal proceedings From time to time, the Group is subject to legal proceedings and claims in the ordinary course of business. The Group records a liability when it is both probable that a liability will be incurred and the amount of the loss can be reasonably estimated. The Group reviews the need for any such liability on a regular basis and has not recorded any material liabilities in this regard during 2017, 2018 and 2019. Legal proceedings alleged subsequent to December 31, 2019 have been disclosed in Note 22. Operating lease commitments The information of lease commitments is provided in Note 10.

Revenue generated by TMG accounted for approximately 89.7% of the Company’s total net revenues during the fiscal year ended December 31, 2019, of which approximately 61.3% was generated from Sweden. Stockholder Class Action On February 13, 2020, a securities class action lawsuit was filed against 500.com Limited and certain of the Group’s current and former officers (collectively, “Defendants”) in the United States District Court for the Eastern District of New York. The complaint alleges, among other things, that the Group made materially misleading statements and omissions regarding its compliance with applicable anti-corruption laws and regulations. The Group believe it has meritorious defenses to each of the claims in this lawsuit and is prepared to vigorously defend against its allegations. There can be no assurance, however, that the Group will be successful. As of the date of this annual report, this lawsuit is in its preliminary stages; at present, the Group cannot reasonably assess the likelihood of any unfavorable outcome, nor can it reasonably estimates the amount, or range, of potential losses, if any, related to the lawsuit. Accordingly, the Group has not recorded any liabilities in respect of this lawsuit as of December 31, 2019. On January 15, 2020, a securities class action lawsuit, making allegations virtually identical with the abovementioned lawsuit filed on February 13, 2020, was filed in the United States District Court for the District of New Jersey. On March 23, 2020, the plaintiff noticed his voluntary dismissal of this case, and on April 8, 2020, the clerk of the Court was ordered to close the case file. As such, this case is now terminated. The Outbreak of COVID-19 In January 2020, the World Health Organization ("WHO") declared a global public health emergency as the novel coronavirus outbreak; later known as the COVID-19 pandemic, which has continued to spread beyond China. The headquarter of the Company is located in Shenzhen, China. Following the outbreak of COVID-19, the PRC government introduced temporary travel restrictions and mandatory quarantines aimed at preventing the spread of COVID-19 within China. While some of these restrictions and quarantines have been relaxed in certain areas, the Company has taken pro-active measures to help protect its employees by implementing self-quarantine measures of at least 14 days for employees that have traveled from other regions within China before they are allowed to report to the Company's offices. In the short term, the COVID-19 pandemic has created uncertainties and risks. With resume of work within China, based on the current situation, the Company does not expect a significant impact on the Company’s operations and financial results in the long run. The extent to which COVID-19 impacts the Company’s results of operations will depend on future development of the circumstances, which is highly uncertain and cannot be predicted with confidence at this time. Restricted Stock Units Incentive Plan On June 26, 2020, the Compensation Committee of the Board of Directors of the Company reached an agreement to issue the number of Class A ordinary shares of 12,977,740 to grant to the employees of the Company. For those rewards, 6,488,870 options were vested on July 1, 2020, and 6,488,870 options were vested on December 1, 2020.

CONDENSED FINANCIAL INFORMATION OF THE PARENT COMPANY The Company performed a test on the restricted net assets of the consolidated subsidiaries and VIEs in accordance with Securities and Exchange Commission Regulation S-X Rule 4-08 (e) (3), “General Notes to Financial Statements” and concluded that it was applicable for the Company to disclose the financial information for the parent company only. The subsidiaries did not pay any dividend to the Company for the periods presented. Certain information and note disclosures generally included in the financial statements prepared in accordance with U.S. GAAP have been condensed and omitted. The note disclosures contain supplemental information relating to the operations of the Company, as such, these statements should be read in conjunction with the notes to the consolidated financial statements of the Company. As of December 31, 2019, the Company did not have significant capital commitments and other significant commitments, or guarantees, except for those which have been separately disclosed in the consolidated financial statements.

The condensed financial information of the parent company has been prepared using the same accounting policies as set out in the Group’s consolidated financial statements except that the parent company used the equity method to account for its investment in its subsidiaries and VIEs. The parent company records its investment in its subsidiaries and VIEs under the equity method of accounting as prescribed in ASC 323, “ Investments-Equity Method and Joint Ventures”. Such investments are presented on the condensed balance sheets as “Investment in subsidiaries and VIEs” and their respective profit or loss as “Equity in profits (losses) of subsidiaries and VIEs” on the condensed statements of comprehensive income (loss). Equity method accounting ceases when the carrying amount of the investment, including any additional financial support, in a subsidiary and VIEs is reduced to zero unless the parent company has guaranteed obligations of the subsidiary and VIEs or is otherwise committed to provide further financial support. If the subsidiary and VIEs subsequently reports net income, the parent company shall resume applying the equity method only after its share of that net income equals the share of net losses not recognized during the period the equity method was suspended. The parent company’s condensed financial information should be read in conjunction with the Group’s consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of presentation and use of estimates	Basis of presentation and use of estimates The accompanying consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”). The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s consolidated financial statements include, but are not limited to, revenue recognition, allowance for doubtful accounts, useful lives of property and equipment, impairment of long-lived assets, long-term investments and goodwill, the purchase price allocation and fair value of non-controlling interests with respect to business combinations, realization of deferred tax assets, uncertain income tax positions and share-based compensation. Actual results could materially differ from those estimates.
Principles of consolidation	Principles of consolidation The consolidated financial statements of the Group include the financial statements of the Company, its subsidiaries and VIEs in which it has a controlling financial interest. The results of the subsidiaries are consolidated from the date on which the Group obtained control and continue to be consolidated until the date that such control ceases. A controlling financial interest is typically determined when a company holds a majority of the voting equity interest in an entity. Furthermore, if the Company demonstrates that it has ability to control the VIEs through its rights to all the residual benefits of the VIEs and its obligation to fund losses of the VIEs then the entity is consolidated. All significant intercompany balances and transactions among the Company, its subsidiaries and VIEs have been eliminated on consolidation.
Reclassification	Reclassification Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no impact on net earnings and financial position.
Convenience translation	Convenience translation Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the noon buying rate of US$1.00 to RMB6.9618 on December 31, 2019 in the city of New York for wire transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York. No representation is made that the RMB amounts could have been, or could be, converted into US$ at such rate.
Foreign currency translation	Foreign currency translation The functional currency of the Company, BVI, 500wan HK, 500.com USA and 500.com JP is the US$. The functional currency of the Multi Group and its subsidiaries is EUR. E-Sun Sky Computer with its VIEs determined their functional currencies to be the RMB, which is their respective local currencies based on the criteria of ASC 830, “ Foreign Currency Matters” . The Group uses the monthly average exchange rate for the year and the spot exchange rate at the balance sheet date to translate the operating results and financial position, respectively. Translation differences are recorded in accumulated other comprehensive income as a component of shareholders’ equity. The Group uses the RMB as its reporting currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates prevailing on the transaction dates. Exchange gains and losses resulting from foreign currency transactions are included in the consolidated statements of comprehensive loss.
Business combinations and noncontrolling interests	Business combinations and noncontrolling interests The Group accounts for its business combinations using the purchase method of accounting in accordance with ASC 805 (“ASC 805”), “ Business Combinations” . The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Group acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations and all contractual contingencies as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over, (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings. The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, forecasted life cycle and forecasted cash flows over that period. For the Company's majority-owned subsidiaries and VIEs, noncontrolling interests are recognized to reflect the portion of their equity which is not attributable, directly or indirectly, to the Group. “Net loss” on the consolidated statements of comprehensive loss include the “net loss attributable to noncontrolling interests”. The cumulative results of operations attributable to noncontrolling interests are also recorded as noncontrolling interests in the Company's consolidated balance sheets.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents represent cash on hand and time deposits, which have original maturities of three months or less when purchased and which are unrestricted as to withdrawal and use. In addition, highly liquid investments which have original maturities of three months or less when purchased are classified as cash equivalents.
Restricted cash and Time deposits	Restricted cash Restricted cash represents cash held by banks which were granted by the government and designated only for the purchase of fixed assets for certain approved projects and deposits in merchant bank where withdrawals are currently restricted. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts presented in the statement of cash flows. The Group adopted the new standard effective January 1, 2018, using the retrospective transition method. All restricted cash was presented on the face of the consolidated balance sheet as “Restricted cash.” Time deposits Time deposits represent deposits in commercial banks with original maturities of greater than three months but less than a year. Interest income from time deposits is included in the consolidated statements of comprehensive loss.
Short-term investments	Short-term investments Short-term investments of the Group are comprised of an investment in targeted asset management plan with fixed rate. The Group accounts for all highly liquid investments with original maturities of greater than three months, but less than 12 months, in accordance with ASC 320-10, “Investments—Debt and Equity Securities”, which are classified as short-term investments. Dividend and interest income, including amortization of the premium and discount arising at acquisition for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short­term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. The Group evaluates whether a decline in fair value below the amortized cost basis is other­than­temporary in accordance with ASC 320. Other­than­temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made.
Allowance for doubtful accounts	Allowance for doubtful accounts Receivables are carried at original invoiced amount less an allowance for doubtful accounts when collection of the amount is no longer probable. In evaluating the collectability of receivable balances, the Group considers factors such as customer circumstances or age of the receivable. Receivables are written off after all collection efforts have ceased. Collateral is not typically required, nor is interest charged on receivables.
Property and equipment, net	Property and equipment, net Property and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets, as follows: Category Estimated Useful Life Estimated Residual Electronics and office equipment 3-5 years 5 % Motor vehicles 5-10 years 2-5 % Leasehold improvements Shorter of lease term or the estimated useful lives of the assets — Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterment that extend the useful lives of property and equipment are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in the consolidated statements of comprehensive loss.
Intangible assets	Intangible assets Intangible assets represent computer software, internet domain name, licensing agreement, and intangible assets arising from business combination. Computer software, internet domain name and licensing agreement purchased from third parties are initially recorded at cost and amortized on a straight line basis over their estimated useful lives of the respective assets. The Group performs valuation of the intangible assets arising from business combination to determine the relative fair value to be assigned to each asset acquired. The acquired intangible assets are recognized and measured at fair value and are expensed or amortized using the straight-line approach over the estimated useful life of the assets. Estimated useful lives of the respective assets are set out as follows: Category Estimated Useful Life Computer software 3-10 years Internet domain name 10 years Licensing agreement Agreement term Intangible assets arising from business combination Licenses and brand name 10 years Mobile applications and software 5 years
Goodwill	Goodwill The Group assesses goodwill for impairment in accordance with ASC 350-20 (“ASC 350-20”), “ Intangibles–Goodwill and Other: Goodwill ”, which requires that goodwill to be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20. Prior to the early adoption of ASU 2017-04, “ Simplifying the Test for Goodwill Impairment ”, on January 1, 2019, the Group has the option to first assess qualitative factors to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20. If the Group believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, the two-step quantitative impairment test described above is required. Otherwise, no further testing is required. In the qualitative assessment, the Group considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. In performing the two-step quantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Group is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Group must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss. In 2018 and 2017, the Group performed qualitative assessments for the reporting units. Based on the requirements of ASC 350-20, the Group evaluated all relevant factors, weighed all factors in their entirety and concluded that the fair value was greater than the carrying amount of the newly acquired entities, and further impairment testing on goodwill was unnecessary as of December 31, 2018 and 2017. In January 2017, the FASB issued Accounting Standards Update No. 2017-04(“ASU 2017-04”), “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. This standard is effective for public business entities in fiscal years beginning after December 15, 2019. Early adoption is permitted. The Group early adopted the ASU 2017-04 on January 1,2019. As triggered by TMG’s temporary suspension of its operations in Sweden since January 2020, the Group performed qualitative and quantitative assessment in accordance with ASU 2017-04 and recognized an impairment loss of RMB129,752 (US$18,638) for goodwill arising from acquisition of TMG as of December 31, 2019.
Impairment of long-lived assets other than goodwill	Impairment of long-lived assets other than goodwill The Group evaluates its long-lived assets or asset group, including property and equipment, intangible assets and right-of-use assets, with finite lives for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be fully recoverable. When these events occur, the Group evaluates the impairment by comparing the carrying amount of the assets to future undiscounted 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 excess of the carrying amount of the asset group over its fair value. The Group provided an impairment loss of nil, nil and RMB181,845 (US$26,120) for intangible assets arising from acquisition of the Multi Group as of December 31, 2017, 2018 and 2019, respectively.
Long-term investments	Long-term investments The Group’s long­term investments consist of equity investments with and equity investments without readily determinable fair value and equity method investments. Prior to adopting ASC Topic 321, Investments Equity Securities (“ASC 321”) on January 1, 2018, the Group carries at cost its investments in investees that do not have readily determinable fair value and over which the Group does not have significant influence, in accordance with ASC Subtopic 325 ­20, Investments ­Other: Cost Method Investments. In accordance with ASC 325, “ Investments-Other” , for investments in an investee over which the Group does not have significant influence and which do not have readily determinable fair value, the Group carries the investment at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings that exceed the Group’s share of earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on 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, cash flow forecasts and financing needs. 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 investment. Pursuant to ASC 321, equity investments, except for those accounted for under the equity method, those that result in consolidation of the investee and certain other investments, are measured at fair value, and any changes in fair value are recognized in earnings. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) to estimate fair value using the net asset value per share (or its equivalent) of the investment, the Group 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. Equity securities with readily determinable fair value are measured at fair values, and any changes in fair value are recognized in earnings. For those equity investments that the Group elects to use the measurement alternative, the Group 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 entity 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 entity has to recognize an impairment loss in net income equal to the difference between the carrying value and fair value. As the Group’s investments in investees do not have readily determinable fair value and over which the Group does not have significant influence, when adopting ASC 321 on January 1, 2018, the Group 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. There was no effect on the Company’s consolidated financial statements subsequent to the adoption of ASC 321. Investments in entities in which the Group can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC 323 (“ASC 323”), “Investments-Equity Method and Joint Ventures”. Under the equity method, the Group initially records its investment at cost and the difference between the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The equity method goodwill is not subsequently amortized and is not tested for impairment under ASC 350. The Group subsequently adjusts the carrying amount of the investment to recognize the Group’s proportionate share of each equity investee’s net income or loss into earnings after the date of investment. The Group will discontinue applying the equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero. Under the conditions that the Group is not required to advance additional funds to an investee and the equity-method investment in ordinary shares is reduced to zero, if further investments are made that have a higher liquidation preference than ordinary shares, the Group would recognize the loss based on its percentage of the investment with the same liquidation preference, and the loss would be applied to those investments of a lower liquidation preference first before being further applied to the investments of a higher liquidation preference. The Group evaluates the equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Group when determining whether an investment has been other­than­temporarily­impaired, includes, but not limited to, the length of the time and the extent to which the market value has been less than cost, the financial performance and near­term prospect of the investee, and the Group's intent and ability to retain the investment until the recovery of its cost. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. According to the above testing, impairment losses of RMB28,781, RMB149,896 and RMB22,353 (US$3,211) for the long-term investments were recognized during the years of 2017, 2018 and 2019, respectively. Investments in limited partnerships greater than 5% are considered more than minor and accounted for using the equity method, unless it is readily apparent that the Group has virtually no influence over the partnership’s financial and operating policies.
Fair Value measurements	Fair value measurements Financial instruments primarily include cash and cash equivalents, restricted cash, time deposits, investment in targeted asset management plan with fixed rate (Note 6), prepayments and other receivables, equity security without readily determinable fair values, equity method investments, and accrued expense and other current liabilities. The Group carries the investment under the measurement alternative method and equity method on other-than-temporary basis. The carrying values of other financial instruments, approximate their fair values due to their short-term maturities. The Group's non-financial assets, including intangible assets, goodwill and fixed assets are measured at fair value when an impairment charge is recognized. The Group applies ASC 820 (“ASC 820”), “Fair Value Measurements and Disclosures ”. ASC 820 defines fair value, establishes a framework for measuring fair value and requires disclosures to be provided on fair value measurement. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1— Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2— Include other inputs that are directly or indirectly observable in the marketplace. Level 3— Unobservable inputs which are supported by little or no market activity. ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach, and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. Related party transactions A related party is generally defined as (i) any person holds 10% or more of the Company’s securities and their immediate families (ii) the Company’s management, (iii) someone that directly or indirectly controls, is controlled by or is under common control with the Company, or (iv) anyone who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. Related parties may be individuals or corporate entities. Transactions involving related parties cannot be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free market dealings may not exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. It is not, however, practical to determine the fair value of amounts due from/to related parties due to their related party nature.

Revenue recognition	Revenue recognition The Group’s revenues were derived principally from online lottery purchase services before voluntary suspension of this service since April 2015. During the voluntary suspension period, the Group diversified its revenue streams, and derived revenues from mobile gaming services, sports information services, online spot commodity trading services and online gaming services. The Group adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the years ended December 31, 2019 and 2018 were presented under ASC 606, and revenues for the year ended December 31, 2017 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. Revenue is recognized when control of promised goods or services is transferred to the Group's customers in an amount of consideration to which the Group expects to be entitled to in exchange for those goods or services. The Group follows the five steps approach for revenue recognition under Topic 606: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the Group satisfies a performance obligation. The Group set up an implementation schedule and analyzed each of the Group’s revenue streams in accordance with ASC 606 to determine the impact on the Group’s consolidated financial statements. After the analyzation, the Group concluded that there was no substantial impact on the Group’s consolidated financial statements upon the adoption of ASC 606. The primary sources of the Group’s revenues are as follows: Online lottery purchase services The Group earns service income for online lottery purchase services and revenues are generated from processing lottery purchase orders from end users (“Service Fee”). The Group receives purchase orders from end users through its online platforms, which include website and mobile applications, and processes the orders with the lottery administration centers. Service Fee is received from the lottery administration centers based on the pre-determined service fee rate and the total amount of the processed orders. Pursuant to ASC 605‑45, “ Principal Agent Considerations ”, the Group records Service Fee on a net basis because the Group is not the primary obligor in the arrangement, but acts as an agent in providing such purchase services. The Group did not generate any revenue from this service since April 2015 when the Group voluntarily suspended the online lottery purchase services due to the change of related government regulation in the PRC. It is uncertain when the services will be resumed. Contingent service fee The Group was also entitled to receive additional Service Fee from lottery administration centers when the total amounts of purchase orders reach an agreed threshold (“Contingent Service Fee”). As the Group is the agent in providing lottery purchase services, any Contingent Service Fee received is recorded as net revenue when the agreed thresholds are reached. Once the Group reaches the agreed thresholds, the Contingent Service Fee is then fixed and not subject to any adjustments. As a result of the voluntarily suspension of the online lottery purchase services mentioned above, the Group did not generate any revenue from this source either since April 2015, and it is uncertain when the Group will be able to generate this fee again in the future. The Super VIP incentive Certain qualified end users (“Super VIP”) are entitled to receive incentives from the Group based on actual purchase amount of each transaction. As the Group does not receive an additional service or benefit from the Super VIP other than service fee earned from lottery administration centers by the Group from the transaction, the incentives are recognized as a reduction of revenue at each year end in accordance with ASC 605‑50, “ Customer Payments and Incentives” . The Group voluntarily suspended the online lottery purchase services due to the change of related government regulation in the PRC, and it is uncertain when the Group will be subject to this fee again in the future. Lottery pool purchase service Lottery pools involve individual end users purchasing a share in a pooled lottery outcome or group of outcomes with other end users. Through the lottery pool purchase service, an end user, an initiator, starts a lottery pool by specifying a range of parameters, such as the lottery portfolio, total purchase amount and payout ratio. The initiator is required to commit a minimum initial purchase amount when they initiate a pool, usually a certain percentage of the total purchase amount. Other end users then join the pool by agreeing to the parameters set by the initiator and committing on the purchase amount. When the total purchase amount as specified by the initiator is reached, the pooled lottery purchase order will be delivered in the manner specified by the initiator. When the actual purchase amount does not reach the total purchase amount as specified by the initiator but reaches a certain percentage of total purchase amount before the lottery pool purchase deadline, the Group contributes the remaining outstanding purchase amount (i.e., residual amount of lottery pool) to complete the lottery pool transaction. If the tickets win prizes from the lottery, the Group distributes the cash prizes to the end users based on the predetermined payout ratio, and the residual amount after distribution is retained by the Group. Since the Group contributes the residual amount of lottery pool to earn Service Fee from the purchase made by the lottery pool and does not provide any service to the lottery administration centers, the residual amount of lottery pool contributed by the Group paid to the lottery administration centers is recognized as a reduction of revenue. The residual amount of the lottery pool retained by the Group after distribution of the prizes are presented as “other operating income”, and recognized upon the announcement of lottery results, as the Group’s principal activity is to provide lottery purchase services to end users. The Group did not generate any revenue from this source either since April 2015, and it is uncertain when the Group will be able to generate this fee again in the future. Mobile gaming services The Group provides mobile gaming services through its designated mobile applications Quiz, Night of Texas Hold’em Poker and Paiyou for Texas Hold’em Poker, and derives revenues from in-game virtual tokens and other virtual items in its game development operations. Once the users purchase virtual tokens or other virtual items through the Group’s own charging system, the Group has an implied obligation to provide the services which enable the virtual tokens or other virtual items to be displayed or used in the games. Thus, the Group initially records the proceeds received from the sales of virtual tokens and other virtual items as deferred revenue, and once they are consumed when the services are rendered to the respective paying players, the Group recognizes the attributable portion of the deferred revenue as revenue. For consumable virtual items representing items that are extinguished after consumption in the form of fixed charges levied on each round of games played, the Group recognizes revenue when the items are consumed and the related services are rendered, since the paying players will not continue to benefit from the virtual items thereafter. For durable virtual items that are accessible and beneficial to paying players over an extended period, the Group recognizes revenue ratably over the average life of durable virtual items for the applicable game, which the Group makes best estimates to be average playing period of paying players. The Group tracks each paying player’s log-in history to estimate the Average playing period of paying players. While the Group believes its estimates to be reasonable based on sufficient available paying player information, it may revise such estimates in the future as the games’ operation periods change or there is indication that the similarities in characteristics and playing patterns of paying players of the games change. Any adjustments arising from changes in the estimates of the average paying player life would be applied prospectively. The Group disposed of a group of components that engage in the mobile gaming services by sale on February 9, 2018, which is reported as discontinued operations for the years ended December 31, 2018 and 2017. Sports information services The Group offers a comprehensive sports information portal via a designated mobile application, which covers (i) real time soccer match information; and (ii) data-driven soccer match predictions generated by proprietary analysis engine. Users can also post free or pay-per-view contents such as proprietary observations and analyses on the sports information portal. The users pay for each information and data subscription at a fixed price, and the Group pays the original information providers a fixed percentage of total purchase amount. Revenue is recognized when users have access to the pay-per-view contents. The Group records the revenue on a net basis because the Group is not the primary obligor to provide the information, but acts as an agent in providing such purchase services. The Group acquired Shenzhen Caiyu Hudong Technology Co., Ltd. (“Shenzhen Caiyu”) to provide sports information service and disposed of Shenzhen Caiyu in November 2017, and continued to provide this information through the Group’s service offering named “Cai Xun Hao,” which was further ceased in March 2019. Online spot commodity trading services The Group provides online spot commodity trading services through the designated website and mobile application in Shenzhen Kaisheng. The Group provides customers with reliable online spot commodity trading for gold trade and delay products across PC and mobile devices. The Group processes customer orders through a commercial bank, and later formed a joint venture with Shenzhen Gold Exchange on May 11, 2018 to provide online spot commodity trading services. Trading commissions are received from the commercial bank based on the pre-determined commission fee rate and the total amount of the processed orders. The Group recognizes revenue at a point in time when an order has been successfully processed and began to generate an immaterial amount of revenue from trading commissions on the online spot commodity trading services since 2017. Online gaming services The Group also provides online lottery betting and online casino platforms through the Group’s designated website after the acquisition of TMG in July 2017. The Group earns difference between betting and winning for online lottery betting services and online casino platforms as revenues that are generated from the registered users. The registered users enter into certain terms and conditions when they first open their accounts with the Group. Lottery and Casino purchase orders are placed by users through the Group’s online platforms view website. Then the Group processes these orders. Prior to processing orders, users prepay all purchase amounts. The Group pays users prizes when there are any winnings attributable to users. The Group records revenues on a net basis by deducting the winning amounts from betting amounts. Revenue comprises the fair value of the consideration received for the provision of internet gaming in the ordinary course of the Group’s activities, which is recognized when the outcome of an event is known. Contract balances The Group does not have any contract assets. The Group's contract liabilities include advance from customers, which is recorded when consideration is received from a customer prior to providing services to the customer under the terms of a contract. As of December 31, 2017, 2018 and 2019, the Group recorded advance from customers balance of RMB4,477, RMB8,283 and RMB5,012 (US$720) respectively, which was included in “Accrued expenses and other current liabilities” on the accompanying consolidated balance sheets. RMB4,477 and RMB8,283 (US$1,190) of deferred revenue included in the opening balances of advance from customers was recognized during the years ended December 31, 2018 and 2019, respectively. The amounts were included in net revenues on the accompanying consolidated statements of comprehensive loss. Refer to Note 21 regarding the discussion of the Group's disaggregate revenue data.
Cost of services	Cost of services Account handling expenses Account handling expenses, which consist primarily of transaction fees charged by banks and third-party payment processors for cash transfers between the users’ accounts on the online platforms including websites and mobile applications and their accounts with banks or third-party payment processors, were RMB2.9 million, RMB6.8 million and RMB2.9 million (US$0.4 million) in 2017, 2018 and 2019, respectively. These costs are expensed as incurred. Server leasing and maintenance expenses Server leasing and maintenance expenses, which consist primarily of leasing expense of servers and other equipment used in providing online services, were RMB8.2 million, RMB6.1 million and RMB4.2 million (US$0.6 million) in 2017, 2018 and 2019, respectively. These costs are expensed as incurred. Lottery insurance expenses Lottery insurance expenses, which consist of insurance premiums payable to insurers for covering the first two categories of winnings in online gaming services for betting on the outcome of lotteries after the acquisition of TMG in July 2017, were RMB7.0 million, RMB20.4 million and RMB9.9 million (US$1.4 million) in 2017, 2018 and 2019, respectively. These costs are expensed as incurred. Platform fee Platform fees, which consist of fees payable to online gaming software suppliers for providing various online casino games on TMG’s websites after the acquisition of TMG in July 2017, were RMB4.5 million, RMB12.1 million and RMB6.6 million (US$0.9 million) in 2017, 2018 and 2019, respectively. These costs are expensed as incurred. Regulatory and compliance fees Regulatory and compliance fees, which consist of fees payable to regulatory bodies such as Gambling Commission, HM Revenue & Customs, Malta Gaming Authority and Certria EOOD after the acquisition of TMG in July 2017, were RMB0.6 million, RMB2.0 million and RMB1.6 million (US$0.2 million) in 2017, 2018 and 2019, respectively. These costs are expensed as incurred. Amortization fees Amortization fees, which consist primarily of amortization of intangible assets arising from business combinations, were RMB13.7 million, RMB31.5 million and RMB28.4 million (US$4.1 million) in 2017, 2018 and 2019, respectively. These costs are recorded in consolidated statements of comprehensive loss on a straight-line basis over the useful life of the intangible assets. Cost of services also comprises employee costs, business tax and surcharges and other direct costs incurred in providing services. These costs are expensed as incurred.
Sales and marketing expenses	Sales and marketing expenses Commission to certain internet companies The Group is responsible to pay certain internet companies a predetermined fixed percentage of the total purchase or deposit amount only if 1) public users enter the Group’s website by redirection through these internet companies’ website, and/or 2) public users have successfully purchased any lottery tickets, virtual tokens, or betting, or deposited certain amounts of cash into their accounts in the Group’s website. The Group is responsible for providing respective services when such public users enter the Group’s website to purchase lottery tickets, virtual tokens or betting. Since these internet companies are providing similar services as those services that have been provided by the Group’s internal sales personnel agent, any relevant costs to be paid by the Group is treated as sales and marketing expenses. Advertising expenditure Advertising costs which consist primarily of expenses associated with advertisements the Group placed on TV channels and other media, are expensed as incurred and are included in “sales and marketing expenses” in the consolidated statements of comprehensive loss. Advertising expenses for the years ended December 31, 2017, 2018 and 2019 were approximately RMB1.0 million, RMB2.4 million and RMB0.5 million (US$0.07 million), respectively. Sponsorship expenses The Group’s sales and marketing expenses also consist of payments under a sponsorship contract. Accounting for sponsorship payments is based upon specific contract provisions. Generally, sponsorship payments are expensed on a straight-line basis over the term of the contract after giving recognition to periodic performance provisions of the contract. Prepayments made under the contract are included in prepayments based on the period to which the prepayments apply.
Service development expenses	Service development expenses Service development expenses consist primarily of personnel-related expenses incurred for the development of, enhancement to, and maintenance of the Group’s website that either (i) did not meet the capitalization criteria in accordance with ASC 350, “Intangibles - Goodwill and other” ; or (ii) met the capitalization criteria but the costs cannot be separated on a reasonably cost-effective basis between maintenance and relatively minor upgrades and enhancements. Service development expenses are recognized as expenses when incurred.
Leases	Leases On January 1, 2019, the Group adopted Accounting Standards Update (ASU) 2016-02, Leases (together with all amendments subsequently issued thereto, “ASC Topic 842”), using the modified retrospective method. The Group elected the transition method which allows entities to initially apply the requirements by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As a result of electing this transition method, previously reported financial information has not been restated to reflect the application of the new standard to the comparative periods presented. The Group elected the package of practical expedients permitted under the transition guidance within ASC Topic 842, which among others, allows the Group to carry forward certain historical conclusions reached under ASC Topic 840 regarding lease identification, classification, and the accounting treatment of initial direct costs. The Group elected not to record assets and liabilities on its consolidated balance sheet for new or existing lease arrangements with terms of 12 months or less. The Group recognizes lease expenses for such leases on a straight-line basis over the lease term. The initial lease liability is equal to the future fixed minimum lease payments discounted using the Group’s incremental borrowing rate, on a secured basis. The initial measurement of the right-of-use asset is equal to the initial lease liability plus any initial direct costs and prepayments, less any lease incentives. The primary impact of applying ASC Topic 842 is the initial recognition of approximately RMB 61,636 of operating lease liabilities, and approximately RMB 54,275 of corresponding right-of-use assets, on the Group’s consolidated balance sheet as of January 1, 2019, for leases classified as operating leases under ASC Topic 840, as well as enhanced disclosure of the Group’s leasing arrangements. There is no cumulative effect to retained earnings or other components of equity recognized as of January 1, 2019. The Group does not have finance lease arrangements as of December 31, 2019. All right-of-use assets are reviewed for impairment. The Group did not record any impairment on the right-of-use lease assets during the year ended December 31, 2019.
Income taxes	Income taxes The Group follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive loss in the period that includes the enactment date. Interest and penalties arising from underpayment of income taxes are computed in accordance with the applicable tax law and is classified in the consolidated statements of comprehensive loss as income tax expense. The amount of interest expense is computed by applying the applicable statutory rate of interest to the difference between the tax position recognized and the amount previously taken or expected to be taken in a tax return. In accordance with the provisions of ASC 740 (“ASC 740”), “Income taxes” the Group recognizes in its financial statements the impact of a tax position if a tax return position or future tax position is “more likely than not” to be sustained upon examination based solely on the technical merits of the position. Tax positions that meet the “more likely than not” recognition threshold are measured at the largest amount of tax benefit, determined on a cumulative probability basis, that has a greater than fifty percent likelihood of being realized upon settlement. The Group’s estimated liability for unrecognized tax position which is included in the “long-term payables” account is periodically assessed for adequacy and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expiration of the statute of limitations. The outcome for a particular audit cannot be determined with certainty prior to the conclusion of the audit and, in some cases, appeal or litigation process. The actual benefits or liability ultimately realized may differ from the Group’s estimates. As each audit is concluded, adjustments, if any, are recorded in the Group’s financial statements. Additionally, in future periods, changes in facts, circumstances, and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which the changes occur. In conjunction with ASC 740, the Group also applied ASC 740‑30 (“ASC 740‑30”), “ Income Taxes: Other Considerations or Special Areas” , to account for the temporary differences arising from the undistributed earnings of the foreign subsidiaries. According to ASC 740‑30, all undistributed earnings of a subsidiary shall be presumed to be transferred to the parent entity. Accordingly, the undistributed earnings of a subsidiary included in consolidated income shall be accounted for as a temporary difference and affect deferred tax expense unless the tax law provides a means by which the investment in a domestic subsidiary can be recovered tax free.
Share-based compensation	Share-based compensation Share options and restricted shares granted to employees and directors Share options and restricted shares granted to employees and directors are accounted for under ASC 718 (“ASC 718”), Compensation - Stock compensation . In accordance with ASC 718, the Group determines whether a share option or restricted shares should be classified and accounted for as an equity award. All grants of share options and restricted shares to employees and directors classified as equity awards are recognized in the financial statements based on their grant date fair values. There were no liability awards granted during any of the periods stated herein. The Group recognizes compensation expense using the accelerated method for share options and restricted shares granted with graded vesting based on service conditions, provided that the amount of compensation expense recognized at any date is at least equal to the portion of the grant-date value of the share options and restricted shares that are vested at that date. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in the subsequent period if actual forfeitures differ from initial estimates. Forfeiture rate is estimated based on historical and future expectation of employee turnover rate and is adjusted to reflect future change in circumstances and facts, if any. Share-based compensation expense is recorded net of estimated forfeitures such that expense was recorded only for those share-based awards that are expected to vest. To the extent the Group revises this estimate in the future, the share-based payments could be materially impacted in the period of revision, as well as in following periods. The compensation costs associated with a modification of the terms of the award (“Modification Award”) are recognized if either the original vesting condition or the new vesting condition has been achieved. Such compensation costs cannot be less than the grant-date fair value of the original award. The incremental compensation cost is measured as the excess of the fair value of the Modification Award over the fair value of the original award at the modification date. Therefore, in relation to the Modification Award, the Group recognizes share-based compensation over the vesting periods of the new options, which comprises, (1) the amortization of the incremental portion of share-based compensation over the remaining vesting term, and (2) any unrecognized compensation cost of original award, using either the original term or the new term, whichever is higher for each reporting period. Share options granted to non-employees Prior to January 1, 2019, the Group records share-based compensation expense for awards granted to non-employees in exchange for services at fair value in accordance with the provisions of ASC 505-50, “ Equity-based payment to non-employees” . As the share options granted to non-employees were fully vested on the grant date, the related compensation expense was fully recognized in the consolidated statement of comprehensive income (loss) on the grant date. Starting January 1, 2019, the Group adopted ASU 2018-07 which aligns accounting for share-based payments issued to nonemployees to that of employees under the existing guidance of Topic 718. The adoption did not pose any impact to the Group's retained earnings as all options granted to non-employees were full vested prior to the adoption. The Group, with the assistance of an independent valuation firm, determined the fair values of the share options recognized in the consolidated financial statements. The binomial option pricing model is applied in determining the estimated fair value of the share options granted to employees and non-employees.
Earnings (Loss) per share	Earnings (loss) per share The Company computes earnings per Class A and Class B ordinary shares in accordance with ASC 260 (“ASC 260”), “ Earnings Per Share” , using the two-class method. Under the provisions of ASC 260, basic net income (loss) per share is computed using the weighted average number of ordinary shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities have been excluded from the computation of diluted net income (loss) per share if their inclusion is anti-dilutive. Potential ordinary shares consist of unvested RSUs and the incremental ordinary shares issuable upon the exercise of stock options. The dilutive effect of unvested RSUs and outstanding stock options is reflected in diluted earnings per share by application of the treasury stock method. The computation of the diluted net income (loss) per share of Class A ordinary shares assumes the conversion of Class B ordinary shares, while the diluted net income (loss) per share of Class B ordinary shares does not assume the conversion of those shares. The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are identical, except with respect to voting. As a result, and in accordance with ASC 260, the undistributed earnings for each year are allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted net loss per share of Class A ordinary shares, the undistributed earnings are equal to net loss for that computation. For the purposes of calculating the Company’s basic and diluted earnings (loss) per Class A and Class B ordinary shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the date of exercise of such options. The Company treated the excess amount of redemption price of the redeemable noncontrolling interest over its fair value as being akin to a dividend, which indirectly affected in the calculation of loss available to ordinary shareholders of the Company used in the loss per share calculation.
Government grants	Government grants Government grants are recognized when there is reasonable assurance that the attached conditions will be complied with. When the grant relates to an expense item, it is recognized in the consolidated statements of comprehensive loss over the period necessary to match the grant on a systematic basis to the related costs. Where the grant relates to an asset acquisition, it is recognized in the consolidated statements of comprehensive loss in proportion to the depreciation of the related assets.
Treasury shares	Treasury shares The Group accounts for treasury shares using the cost method. Under this method, the cost incurred to purchase the shares is recorded in the treasury shares account on the consolidated balance sheets. At retirement, the ordinary shares account is charged only for the aggregate par value of the shares. The excess of the acquisition cost of treasury shares over the aggregate par value is allocated between additional paid-in capital (up to the amount credited to the additional paid-in capital upon original issuance of the shares) and retained earnings.
Recent accounting pronouncements	Recent accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments (Topic 326)”, and issued subsequent amendments to the initial guidance, transitional guidance and other interpretive guidance between November 2018 and March 2020 within ASU 2018-19, ASU 2019-04, ASU 2019-05 , ASU 2019-11, ASU 2020-02 and ASU 2020-03. ASU 2016-13 introduces new guidance for credit losses on instruments within its scope, which significantly changes the way entities recognize impairment of many financial assets by requiring immediate recognition of estimated credit losses expected to occur over their remaining life, instead of when incurred. For public business entities, this ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt this ASU through a cumulative effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Group is in the process of evaluating the potential effect on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018­13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018­13”) 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 Group does not expect any significant impact on its consolidated financial statements and related disclosures as a result of adopting the new standard. In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes", which simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in ASC 740 and also clarifies and amends existing guidance to improve consistent application. The ASU is effective for fiscal years beginning after December 15, 2020, and will be applied either retrospectively or prospectively based upon the applicable amendments. Early adoption is permitted. The Group is currently evaluating the potential impacts of ASU 2019-12 on its consolidated financial statements. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Group does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its consolidated financial condition, results of operations, cash flows or disclosures.
