If the Company 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, then the impairment test described below is required. The Company compares the fair values of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired. If the carrying amount of a reporting unit exceeds its fair value, impairment is recognized for the difference, limited to the amount of goodwill recognized for the reporting unit.

The Company evaluates three indicators of control in accordance with ASU 2016-08: 1) For hardware sales, the Company is the most visible entity to customers and assumes fulfilment risk and risks related to the acceptability of products, including addressing customer complaints directly and handling of product returns or refunds directly. 2) The Company assumes inventory risk after taking the title from vendors and is responsible for product damage during shipment period prior to acceptance of its customers and is also responsible for product return if the customer is not satisfied with the products. 3) The Company determines the resale price of hardware products. 4) The Company is the party that directs the use of the inventory and can prevent the vendor from transferring the product to a customer or to redirect the products to a different customer.

The Company provides its advertising service to channel providers where the amounts cost per action are also fixed and determinable. Revenue is recognized at a point of time when agreed actions are performed. The Company considers itself as provider of the services under the CPA model as it has the control of the services at any time before it is transferred to the customers which is evidenced by 1) having a right to a service to be performed by the other party, which gives the Company the ability to direct that party to provide the service to the customers on the Company’s behalf. 2) having discretion in setting the price for the service 3) billing monthly advertising fee directly to customers by settling valid CPA data with customers. Therefore, the Company acts as the principal of these arrangements and reports revenue earned and costs incurred related to these transactions on a gross basis. The Company also provides advertisement services through influencers on social networks. The Company charges advertisers a fixed rate, which is generally a fixed percentage of total value of merchandise sold over a specific period (“GMV”).

The amendments in Update 2016-13 added Topic 326, Financial Instruments — Credit Losses, and made several consequential amendments to the Codification. Update 2016-13 also modified the accounting for available-for-sale debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments — Credit Losses — Available-for-Sale Debt Securities. The amendments in this Update address those stakeholders’ concerns by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information.

If the Company 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, then the impairment test described below is required. The Company compares the fair values of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired. If the carrying amount of a reporting unit exceeds its fair value, impairment is recognized for the difference, limited to the amount of goodwill recognized for the reporting unit.

Deferred tax is charged or credited in the income statement, except when it is related to items credited or charged directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.25in"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">An uncertain tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. No penalties and interest incurred related to underpayment of income tax are classified as income tax expense in the period incurred.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p id="xdx_84B_ecustom--OtherIncomePolicyTextBlock_zR13uNUnIHV1" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="text-decoration: underline"><span id="xdx_86C_zvgvEK0rPcyi">Other Income, net</span></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Other Income includes government subsidies which are amounts granted by local government authorities as an incentive for companies to promote development of the local technology industry.

For lease terms of twelve months or fewer, a lessee is permitted to make an accounting policy election not to recognize lease assets and liabilities. The Company also adopted the practical expedient that allows lessees to treat the lease and non-lease components of a lease as a single lease component. On January 1, 2022, the Company recognized approximately RMB 5.7 million (USD 0.9 million) of right of use (“ROU”) assets and approximately RMB 5.7 million (USD 0.9 million) of operating lease liabilities based on the present value of the future minimum rental payments of leases, using incremental borrowing rate of 5.6% to 7%.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.25in"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">The Company determines if a contract contains a lease at inception.

The Company has elected the short-term lease exception, therefore operating lease ROU assets and liabilities do not include leases with a lease term of twelve months or less.

Potential ordinary shares that have an anti-dilutive effect (i.e., those that increase income per share or decrease loss per share) are excluded from the calculation of diluted EPS. </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p id="xdx_840_ecustom--StatutoryReservesPolicyTextBlock_zRgMLIz2zrhd" style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="text-decoration: underline"><span id="xdx_861_z7pzjvFWpXei">Statutory reserves</span></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in">Pursuant to the laws applicable to the PRC, PRC entities must make appropriations from after-tax profit to the non-distributable “statutory surplus reserve fund”.

The amendments in Update 2016-13 added Topic 326, Financial Instruments — Credit Losses, and made several consequential amendments to the Codification. Update 2016-13 also modified the accounting for available-for-sale debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments — Credit Losses — Available-for-Sale Debt Securities. The amendments in this Update address those stakeholders’ concerns by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. In November 2019, the FASB issued ASU No. 2019-10, which to update the effective date of ASU No. 2016-02 for private companies, not-for-profit organizations and certain smaller reporting companies applying for credit losses, leases, and hedging standard.
