SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) and applicable rules and regulations of the Securities and Exchange Commission, regarding financial reporting, and include all normal and recurring adjustments that management of the Group considers necessary for a fair presentation of its financial position and operation results. Certain information and footnote disclosures normally included in financial statements prepared in conformity with US GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these statements should be read in conjunction with the Group’s unaudited consolidated financial statements as of and for the three years in the periods ended December 31, 2017. (b) Liquidity As of December 31, 2017 and June 30, 2018, the Group had cash and cash equivalents of US$13.1 million and $1.3 million, respectively. As of June 30, 2018, the Group has accumulated deficit of US$71.5 million and net cash outflows of US$11.8 million for the six months then ended. These conditions raise substantial doubt about the Group’s ability to continue as a going concern and therefore, the Group is exposed to liquidity risk as it may not have sufficient working capital to meet its commitments and business needs. The Group’s ability to fund its operations is based on its ability to generate cash, its ability to attract investors and its ability to borrow funds on reasonable economic terms. The Group’s ability to continue as a going concern is dependent on management’s ability to successfully execute its business plan and generate positive cash inflows. The Group is now in the process of completing a public offering to secure funding. Therefore, the management is of the opinion that it will be able to meet its payment obligations for the next twelve months from the date of issuance of the unaudited condensed consolidated financial statements. Based on the above considerations, the Group’s unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. (c) Long-term investment The Group’s long-term investment represents cost method investment purchased during the six months period ended June 30, 2018. In accordance with ASC 325-20 (“ASC 325-20”), Investments-Other: Cost Method Investments, for investments in investees over which the Group does not have significant influence, the Group carries the investments at cost and only adjusts for other-than-temporary declines in fair value and distributions of earnings. The Group’s management regularly evaluates the impairment of its cost method investments based on the performance and financial position of the investees as well as other evidence of estimated market values. Such evaluation includes, but is not limited to, reviewing the investees’ cash position, recent financing, projected and historical financial performance, cash flow forecasts and current and future financing needs. An impairment loss is recognized in the consolidated statements of comprehensive income 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. (d) Recent accounting pronouncements The Group is an emerging growth company (’‘EGC’’) as defined by the Jumpstart Our Business Startups Act (’‘JOBS Act’’). The JOBS Act provides that an EGC can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an EGC to delay adoption of certain accounting standards until those standards would otherwise apply to private companies. The Group elected to take advantage of the extended transition period. However, this election will not apply should the company cease to be classified as an EGC. In May 2014, the Financial Accounting Standards Board (’‘FASB’’) issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU 2014-09 by one year. As a result, ASU 2014-09 is effective for the Group for annual reporting periods beginning January 1, 2019 and interim periods within annual periods beginning January 1, 2020. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers—Principal versus Agent Considerations, which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers—Identifying Performance Obligations and Licensing, which clarify guidance related to identifying performance obligations and licensing implementation guidance contained in ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers— Narrow-Scope Improvements and Practical Expedients, which addresses narrow-scope improvements to the guidance on collectability, non-cash consideration, and completed contracts at transition and provides practical expedients for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The effective dates for these amendments are the same as the effective date of ASU No 2014-09. Early adoption is permitted, and the standard permits the use of either the retrospective or cumulative effect transition method. The Group does not plan to early adopt the standard and amendments and it is in the process of developing a plan for evaluating the impact of adoption of these guidance on its unaudited consolidated financial statements, including the selection of the adoption method, the identification of differences, if any, from the application of the guidance, and the impact of such differences, if any, on its unaudited consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. ASU 2016-01 is effective for the Group beginning January 1, 2019 with interim periods within annual periods beginning January 1, 2020. Early adoption is permitted no earlier than the fiscal year beginning January 1, 2018 including interim periods within that year. The Group does not plan to early adopt ASU 2016-01 and it is currently evaluating the impact of adopting this standard on its unaudited consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases, which specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. ASU 2016-02 is effective for the Group for annual reporting periods beginning January 1, 2020 and interim periods within annual periods beginning January 1, 2021. Early adoption is permitted. The Group does not plan to early adopt ASU 2016-02 and it is currently evaluating the impact of adopting the standard on its unaudited consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. ASU 2016-13 changes the impairment model for most financial assets and certain other instruments. The standard will replace “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. The standard is effective for public business entities for annual periods beginning after December 15, 2019, and interim periods therein, and annual reporting periods beginning after December 15, 2020, and interim periods within annual periods beginning after December 15, 2021 for all other entities. Early adoption is permitted. The Group does not plan to early adopt ASU No. 2016-13 and it is evaluating the effect that this guidance will have on its unaudited consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (COLIs) (including bank-owned life insurance policies (BOLIs)); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. In November 2016, the FASB issued ASU 2016-18, Statements of Cash Flow (Topic 230): Restricted Cash, which requires that a statement of cash flows explain the change during the period in the total cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amount shown on the statement of cash flows. ASU 2016-15 and ASU 2016-18 are effective for the Group for annual reporting periods beginning January 1, 2019 and interim periods within annual periods beginning January 1, 2020. Early adoption is permitted. The Group does not plan to early adopt ASU 2016-15 and ASU 2016-18 and it is evaluating the impacts that these standards will have on its unaudited consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. ASU 2017-01 clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. ASU 2017-01 is effective for the Group for annual reporting periods beginning January 1, 2020 and interim periods within annual periods beginning January 1, 2021, with early adoption permitted for transactions that have not been reported in previously issued (or available to be issued) financial statements. The Group does not plan to early adopt ASU 2017-01 and does not expect the impact that this standard will have a material impact on its unaudited consolidated financial statements. In January 2017, the FASB issued Accounting Standards Update No. 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 for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2020. Early adoption is permitted. The Group does not plan to early adopt ASU 2017-04 and it is currently evaluating the impact of adopting this standard on its unaudited consolidated financial statements. | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Basis of presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). (b) Liquidity As of December 31, 2017, the company has accumulated deficit of US$74,231 and has suffered net loss of US$12,359 and negative cash flow from operating of US$14,939 for the year then ended. These condition raises substantial doubt about the Group’s ability to continue as a going concern. When preparing the consolidated financial statements as of December 31, 2017 and for the year then ended, the Group’s management concluded that a going concern basis of preparation was appropriate after analyzing the forecasted cash flows for the next twelve months, which indicates that the Group will have sufficient liquidity through March 2019. In preparing the forecasted cash flow analysis, management took into account of the expected net cash inflows to be funded by the public offering and short term debt of approximately US$32,000. As a result, management prepared the consolidated financial statements assuming the Group will continue as a going concern. However, there is no assurance that the public offering can be completed in a timely manner or at all, and there is no assurance that any short term debt is available at acceptable terms. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. (c) Principles of consolidation The consolidated financial statements include the financial statements of the Group, its subsidiaries and Consolidated VIEs, for which, the Group is the primary beneficiary. All significant inter-company transactions and balances between the Group, its subsidiaries and the Consolidated VIEs are eliminated upon consolidation. Results of acquired subsidiaries and its Consolidated VIEs are consolidated from the date on which control is transferred to the Group. (d) Use of estimates The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the year. Areas where management uses subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets and intangible assets, assessing the initial valuation of the assets acquired and liabilities assumed in a business combination and the subsequent impairment assessment of long-lived assets, intangible assets and goodwill, determining the provisions for accounts receivable and inventories, accounting for deferred income taxes and uncertain tax benefits, valuation for share-based compensation arrangements, warrants for Series D convertible redeemable preferred shares, beneficiary conversion feature for Series E Preferred Shares. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences may be material to the consolidated financial statements. (e) Foreign currency The functional currency of the Group and its non-PRC subsidiaries, excluding Borqs India, is the United States dollar. The functional currency of Borqs India is Rupee, whereas the functional currency of the Group’s PRC subsidiaries and its Consolidated VIEs is the Chinese Renminbi (“RMB”) as determined based on the criteria of ASC 830, Foreign Currency Matters Assets and liabilities of the Group’s PRC subsidiaries are translated into US$ at fiscal year-end exchange rates. Equity amounts are translated at historical exchange rates. Income and expense items are translated at average exchange rates prevailing during the fiscal year. Translation adjustments arising from translation of foreign currency financial statements are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive (loss) income in the consolidated statements of comprehensive income (loss). (f) Cash and cash equivalents Cash and cash equivalents consist of cash on hand and bank deposits which are unrestricted as to withdrawal and use. All highly liquid investments with a stated maturity of 90 days or less from the date of purchase are classified as cash equivalents. (g) Restricted cash Restricted cash mainly represents short-term deposits with China United Network Communications Group Co., Ltd. (“China Unicom”) as guarantee for minimum purchase requirements, and therefore are not available for the Group’s use until the end of contract period with China Unicom. (h) Accounts receivable Accounts receivable are carried at net realizable value. An allowance of doubtful accounts is recorded in the period when the collection of full amount is no longer probable. The Group reviews the accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Group considers many factors, including the age of the balance, the customer’s payment history, its current credit-worthiness and current economic trends. As of December 31, 2016 and 2017, the Group evaluated and wrote off the doubtful accounts as they were determined to be uncollectible. Thus, there was no allowance for doubtful accounts outstanding. (i) Inventories Inventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out method. Adjustments to reduce the cost of inventories to its net market value are made, if required, for decreases in sales prices, obsolescence or similar reductions in the estimated net realizable value. Inventories provision of US$1,038 and US$918 was recorded as of December 31, 2016 and 2017, respectively. (j) Property and equipment Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows: Category Estimated useful life Computer and network equipment 3-5 years Office equipment 5 years Motor vehicles 5 years Leasehold improvements Over the shorter of lease term or the estimated useful lives of the assets Repair and maintenance costs are charged to expense as incurred, whereas the costs of betterments that extend the useful life of property and equipment are capitalized as additions to the related assets. Retirements, sale and disposals of assets are recorded by removing the cost and accumulated depreciation with any resulting gain or loss reflected in the consolidated statements of operations. Property and equipment that are purchased or constructed which require a period of time before the assets are ready for their intended use are accounted for as construction-in-progress. Construction-in-progress is recorded at acquisition cost, including installation costs. Construction-in-progress is transferred to specific property and equipment accounts and commences depreciation when these assets are ready for their intended use. (k) Intangible assets Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets acquired in a business combination are recognized initially at fair value at the date of acquisition. Intangible assets with finite useful lives are amortized using the straight-line method. These amortization methods reflect the estimated pattern in which the economic benefits of the respective intangible assets are to be consumed. Development costs of software to be sold, leased, or otherwise marketed are subject to capitalization beginning when technological feasibility is reached, in accordance with ASC 985-20, Costs of Software to be Sold, Leased, or Marketed Intangible assets have weighted average useful lives from the date of purchase as follows: Purchased software 5.8 years MVNO license 10 years Capitalized software development costs 3 years Internal-use software 5 years (l) Goodwill Goodwill represents the excess of the purchase price over the amounts assigned to the fair value of the assets acquired and the liabilities assumed of an acquired business. The Group’s goodwill as of December 31, 2016 and 2017 was related to its acquisition of Yuantel Investment. In accordance with ASC 350, Goodwill and Other Intangible Assets ( ) The performance of the impairment test in accordance to ASC 350 involves a two-step process. The first step of the impairment test involves comparing the fair value of the reporting unit with its carrying amount, including goodwill. Fair value is primarily determined by computing the future discounted cash flows expected to be generated by the reporting unit. If the reporting unit’s carrying value exceeds its fair value, goodwill may be impaired. If this occurs, the Group performs the second step of the goodwill impairment test to determine the amount of impairment loss. 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’s goodwill. If the implied goodwill fair value is less than its carrying value, the difference is recognized an impairment loss. In accordance with ASC 350, the Group assigned and assessed goodwill for impairment at the reporting unit level. A reporting unit is an operating segment or one level below the operating segment. The Group has determined that it has two operating segments as its reporting units, namely Yuantel and Connected Solution. Goodwill is recorded at the Yuantel reporting unit. (m) Impairment of long-lived assets The Group evaluates its long-lived assets or asset group, including intangible assets with indefinite and finite lives, for impairment. Intangible assets with indefinite lives that are not subject to amortization are tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the assets might be impaired in accordance with ASC 350. Such impairment test compares the fair values of assets with their carrying values with an impairment loss recognized when the carrying values exceed fair values. For long-lived assets and intangible assets with finite lives that are subject to depreciation and amortization are tested 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 an asset or a Group of long-lived assets may not be recoverable. When these events occur, the Group evaluates impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group would recognize an impairment loss based on the excess of the carrying amount of the asset group over its fair value. (n) Fair value of financial instruments The Group’s financial instruments include cash and cash equivalents, restricted cash, accounts receivable and payable, accounts receivable from related parties, receivable from MVNO franchisees, short-term and long-term bank borrowings, warrants for Series D convertible redeemable preferred shares and Convertible Redeemable Preferred Shares. Other than the long-term bank borrowings, warrants for Series D convertible redeemable preferred shares, the carrying values of these financial instruments approximate their fair values due to their short-term maturities. The Group applies ASC 820, Fair Value Measurements and Disclosures 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 — 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. During the years ended December 31, 2016 and 2017, there was no financial instrument measured at fair value. The warrants for Series D convertible redeemable preferred shares were classified as level 3 and fair valued using the binomial option pricing model as of December 31, 2016. The carrying amounts of long-term bank borrowings approximated their fair values since they bear interest rates which approximate market interest rates. The Convertible Redeemable Preferred Shares are initially recognized at its fair value on the closing date, at the issuance price, net of issuance cost. (o) Revenue recognition The Group is mainly engaged in the business of providing 1) Android+ platform solutions and services, 2) hardware product sales, and 3) MVNO services. The Group recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed and determinable, and collectability is reasonably assured. 1. Android+ platform solutions and services Android+ platform solutions The Group provides customized Android+ software platform solutions that are developed to maximize the commercial grade quality or performance of open source Android+ software for integration with particular chipsets. The Group also provides customized Android+ service platform solutions that are end to end software developed for mobile operators to allow data synchronization between their platform and mobile devices. The Group charges its customers, mainly including mobile device manufacturers and mobile operators, fixed fees for project-based software contracts, as well as per chip or per mobile device royalty fees. The project-based software contracts are generally considered multiple element arrangements as they consist of perpetual software licenses, software development services such as customization, modification, implementation and integration, and post-contract customer support (“PCS”) where customers have the right to receive bug fixes, telephone support and unspecified upgrades on a when-and-if available basis. Pursuant to ASC 985-605, Revenue Recognition: Software Revenue Recognition: Contract Accounting As the Group was unable to establish vendor specific objective evidence of the fair value of PCS and PCS is the only undelivered element upon completion of software projects, the entire software project fixed fees are recognized ratably over the PCS service period. PCS service periods are generally 12 months, with ranges from six months to three years, and commences upon completion of customer acceptance of the completed software projects. Costs incurred to complete the software projects are deferred to match revenue recognition. Where the Group is entitled to receive on going usage based royalties determined based on the chip or mobile device sales, the usage-based royalties are recognized according to the customers’ usage reports, generally on a quarterly basis. Service contracts The Group provides research and development services to certain customers for their mobile-computing related development projects where fees are charged on a time and material basis and the Group is not responsible for the outcome of such development projects. The revenue is recognized proportionately as the services are delivered and is included as software revenues on the consolidated statement of operations. 2. Hardware product sales The Group provides total solutions on original design manufacturer (“ODM”) basis to customers of mobile devices. Revenue is recognized when sale of each final hardware product to the customers are delivered. Warranty is provided to all customers, which is not considered an additional service; rather, an integral part of the product sales. ASC 450, Contingencies, 3. MVNO On July 11, 2014, the Group, through the VIE, acquired and obtained control of Yuantel Investment, which mainly operates the MVNO business. The license to operate such MVNO business is issued by the Chinese Ministry of Industry and Information Technology and the core mobile network is provided by the PRC government owned China Unicom. Yuantel Investment receives wholesale rates for mobile voice and data services from China Unicom and repackages the voice and data services into competitive bundles for Chinese consumers. In accordance with ASC 605-45, Revenue Recognition; Principal agent consideration, Sales of the bundles are mostly made through agents and franchisees. Bundled services sold to agents are discounted and not refundable to the Group. The Group accounts for such discounts as reductions of revenue in accordance with ASC 605-50 (“ASC 605-50”) Customer Payments and Incentives The Group enters into profit sharing arrangements with franchisees under which bundled services may be returned to the Group if not sold to the consumers. The franchisees receive certain percentages of profits made by the Group on the sales of the bundled services as they are used by the consumers. The Group accounts for profit sharing with franchisees as selling expenses in the consolidated statements of operations. Pursuant to the Group’s policy, the amount of discounts that may be provided by the franchisees to consumers is capped at 5%, based on which, the Group recognized the maximum amount of discounts that may be provided by the franchisees as reductions of revenue in accordance with ASC 605-50. (p) Cost of revenues Cost of revenues consists primarily of telecommunication costs, depreciation of long-lived assets, amortization of acquired intangible asset, payroll and other related costs of operations. Deferred cost of revenues was US$1,658 and US$3,149 for the years ended December 31, 2016 and 2017. (q) Advertising expenditures Advertising expenditures are expensed as incurred and are included in sales and marketing expenses, which amounted to US$46, US$78 and US$45 for the years ended December 31, 2015, 2016 and 2017, respectively. (r) Research and development expenses Research and development expenses include payroll, employee benefits, and other headcount-related expenses associated with research and platform development. Research and development expenses also include rent, depreciation and other related expenses. Research and development expenses are expensed as incurred. (s) Government grants Government grants are provided by the relevant PRC municipal government authorities to subsidize the cost of certain technology development projects. The amount of such government grants are determined solely at the discretion of the relevant government authorities and there is no assurance that the Group will continue to receive these government grants in the future. Government grants are recognized when it is probable that the Group will comply with the conditions attached to them, and the grants are received. When the grant relates to an expense item, it is recognized in the consolidated statement of operations over the period necessary to match the grant on a systematic basis to the costs that it is intended to compensate, as a reduction of the related operating expense. When the grant relates to an asset, it is recognized as deferred government grants and released to the consolidated statement of operations in equal amounts over the expected useful life of the related asset, when operational, as a reduction of the related depreciation expense. (t) Leases Leases are classified at the inception date as either a capital lease or an operating lease. The Group did not enter into any leases whereby it is the lessor for any of the periods presented. As the lessee, a lease is a capital lease if any of the following conditions exists: a) ownership is transferred to the lessee by the end of the lease term, b) there is a bargain purchase option, c) the lease term is at least 75% of the property’s estimated remaining economic life, or d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. A capital lease is accounted for as if there was an acquisition of an asset and an incurrence of an obligation at the inception of the lease. The Group did not enter into any capital leases for the years ended December 31, 2015, 2016 and 2017. All other leases are accounted for as operating leases wherein rental payments are expensed on a straight-line basis over the periods of their respective lease terms. The Group leases office space under operating lease agreements. Certain lease agreements contain rent holidays and escalating rent. Rent holidays and escalating rent are considered in determining the straight-line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the lease property for purposes of recognizing lease expense on a straight-line basis over the term of the lease. (u) Income taxes The Group accounts for income taxes using the liability method. Current income taxes are provided for in accordance with the laws of the relevant tax authorities. 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 against 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 income in the period that includes the enactment date. The Group applies ASC 740, Accounting for Income Taxes, , The Group has elected to classify interest related to unrecognized tax benefits, if and when required, as part of “income tax expense” in the consolidated statements of operations. The Group elected to early adopt ASU No. 2016-16, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. (v) Share-based compensation The Group accounts for share-based compensation in accordance with ASC 718, Compensation-Stock Compensation: Overall In accordance with ASC 718, the Group determines whether an award should be classified and accounted for as a liability award or equity award. All grants of share-based awards to employees classified as equity awards are measured based on their grant date fair values and recognized as compensation expense over the requisite service period and/or performance period in the consolidated statements of operations. The Group recognizes compensation expense using the accelerated method for share-based awards granted with service and performance conditions. According to ASC 718, the amount of compensation cost recognized (or attributed) when achievement of a performance condition is probable depends on the relative satisfaction of the performance condition based on performance to date. According to ASC 718, probable means the future event or events are likely to occur and the Group interprets “probable” to be generally in excess of a 70% likelihood of occurrence. The Group elected to account for forfeitures as they occur. (w) Comprehensive income (loss) Comprehensive income (loss) is defined as the (decrease) increase in equity of the Group during a period from transactions and other events and circumstances excluding transactions resulting from investments by owners and distributions to owners. Accumulated other comprehensive income (loss) of the Group includes foreign currency translation adjustments related to the Group and its PRC subsidiaries, whose functional currency is RMB. (x) Segment reporting In accordance with ASC 280 “ Segment Reporting (y) Employee benefits The full-time employees of the Group’s PRC subsidiaries are entitled to staff welfare benefits including medical care, housing fund, pension benefits and unemployment insurance, which are governmental mandated defined contribution plans. These entities are required to accrue for these benefits based on certain percentages of the employees’ respective salaries, subject to certain ceilings, in accordance with the relevant PRC regulations, and make cash contributions to the state-sponsored plans out of the amounts accrued. (z) Comparatives Certain items reported in the prior year’s consolidated financial statements have been reclassified to conform to the current year’s presentation. (aa) (Loss) earnings per share (Loss) earnings per share is computed by dividing net (loss)/income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period using the two-class method. Under the two-class method, net income (loss) is allocated between ordinary shares and other participating securities based on their participating rights. The Group’s Convertible Redeemable Preferred Shares (Note 19) were participating securities. As the participating securities do not share the losses of the Group, the computation of basic earnings per share using two-class method is not applicable when the Group is at a net loss position. Diluted (loss) earnings per share is calculated by dividing net (loss) income attributable to ordinary shareholders by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary equivalent shares consist of shares issuable upon the exercise of share options using the treasury stock method and shares issuable upon the conversion of the Group’s Convertible Redeemable Preferred Shares using the if-converted method. Ordinary equivalent shares are not included in the denominator of the diluted loss per share calculation when inclusion of such shares would be anti-dilutive.
