The exclusive option agreement has an initial term of ten years, and at the end of the initial term shall be renewed for a further term as specified by Dada Glory or terminated by Dada Glory in its sole discretion.

Powers of Attorney

Pursuant to the power of attorney, each of the shareholders of the VIE has executed a power of attorney to irrevocably authorize Dada Glory, or any person designated by Dada Glory, to act as its attorney-in-fact to exercise all of its rights as a shareholder of the VIE, including, but not limited to, the right to propose, convene and attend shareholders’ meetings, (ii) vote on any resolution on behalf of the shareholders that require the shareholders to vote under PRC law and the VIE’s articles of association, such as the sale, transfer, pledge and disposal of all or part of a shareholder’s equity interest in the VIE, and designate and appoint the VIE’s legal representative, director, supervisor, chief executive officer and other senior management members on behalf of the shareholders. The powers of attorney will remain effective until such shareholder ceases to be a shareholder of the VIE or otherwise instructed by Dada Glory.

U.S. GAAP provides guidance on the identification of VIE and financial reporting for entities over which control is achieved through means other than voting interests. The Group evaluates each of its interests in an entity to determine whether the investee is a VIE and, if so, whether the Group is the primary beneficiary of such VIE. In determining whether the Group is the primary beneficiary, the Group considers if the Group (1) has power to direct the activities that most significantly affect the economic performance of the VIE, and (2) receives the economic benefits of the VIE that could be significant to the VIE. If deemed the primary beneficiary, the Group consolidates the VIE.

The irrevocable powers of attorney described above have conveyed all shareholder rights held by the VIE’s shareholders to Dada Glory, including the right to appoint board members who nominate the general managers of the VIE to conduct day-to-day management of the VIE’s businesses, and to approve significant transactions of the VIE. The exclusive option agreements provide Dada Glory with a substantive kick-out right of the VIE shareholders through an exclusive option to purchase all or any part of the shareholders’ equity interest in the VIE at the lowest price permitted under the PRC laws then in effect. In addition, through the exclusive business cooperation agreement, Dada Glory has established the right to receive benefits from the VIE that could potentially be significant to the VIE, and through the share pledge agreement, Dada Glory has, in substance, an obligation to absorb losses of the VIE that could potentially be significant to the VIE. As these contractual arrangements allow the Group to effectively control the VIE and to derive substantially all of the economic benefits from it, the Group has consolidated the VIE.

Risks in relation to the VIE structure

The Company believes that the contractual arrangements amongst Dada Glory, Shanghai Qusheng and their respective shareholders are in compliance with PRC law and are legally enforceable. The shareholders of Shanghai Qusheng are also shareholders of the Company and therefore have no current interest in seeking to act contrary to the contractual arrangements. However, Shanghai Qusheng and their shareholders may fail to take certain actions required for the Company’s business or to follow the Company’s instructions despite their contractual obligations to do so. Furthermore, if Shanghai Qusheng or their shareholders do not act in the best interests of the Company under the contractual arrangements and any dispute relating to these contractual arrangements remains unresolved, the Company will have to enforce its rights under these contractual arrangements through the operations of PRC law and courts and therefore will be subject to uncertainties in the PRC legal system. All of these contractual arrangements are governed by PRC law and provided for the resolution of disputes through arbitration in the PRC. Accordingly, these contracts would be interpreted in accordance with PRC law and any disputes would be resolved in accordance with PRC legal procedures. As a result, uncertainties in the PRC legal system could limit the Company’s ability to enforce these contractual arrangements, which may make it difficult to exert effective control over Shanghai Qusheng, and its ability to conduct the Company’s business may be adversely affected.

The following amounts and balances of the consolidated VIE were included in the Group’s consolidated financial statements after the elimination of intercompany balances and transactions:

The VIE contributed approximately 0.3%, 0.1% and 0.1% of the Group’s consolidated net revenues for the years ended December 31, 2018, 2019 and 2020, respectively. As of December 31, 2019 and 2020, the VIE accounted for approximately 0.4% and 0.3% of the consolidated total assets, and approximately 1.0% and 0.7% of the consolidated total liabilities, respectively.

There are no terms in any arrangements, considering both explicit arrangements and implicit variable interests that require the Group or its subsidiaries to provide financial support to the VIE. However, if the VIE was ever to need financial support, the Group or its subsidiaries may, at its option and subject to statutory limits and restrictions, provide financial support to its VIE through loans to the shareholders of the VIE or entrustment loans to the VIE.

The Group believes that there are no assets held in the consolidated VIE that can be used only to settle obligations of the VIE, except for paid-in capital, additional paid-in capital ("APIC") and the PRC statutory reserves. As the consolidated VIE is incorporated as a limited liability company under the PRC Company Law, creditors of the VIE do not have recourse to the general credit of the Group for any of the liabilities of the consolidated VIE.

Relevant PRC laws and regulations restrict the VIE from transferring a portion of their net assets, equivalent to the balance of their paid-in capital, APIC and PRC statutory reserve, to the Group in the form of loans and advances or cash dividends.

2.3 Use of estimates

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, disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Group’s management reviews these estimates based on information that is currently available. Changes in facts and circumstances may cause the Group to revise its estimates. Significant accounting estimates reflected in the Group’s consolidated financial statements mainly include the useful lives of property and equipment and intangible assets, assumptions used to measure the impairment of goodwill, property and equipment and intangible assets, assumptions impacting the valuation of ordinary shares and share options, and realization of deferred tax assets.

2.4 Functional currency and foreign currency translation

The Group uses Renminbi ("RMB") as its reporting currency. The functional currency of the Company is the United States dollar ("US$" or "USD"). The functional currency of the Company’s subsidiaries, VIE and VIE’s subsidiaries is RMB or USD as determined based on the economic facts and circumstances.

Transactions denominated in other than the functional currencies are re-measured into the functional currency of the entity at the exchange rates prevailing on the transaction dates. Foreign currency denominated financial assets and liabilities are re-measured at the balance sheet date exchange rate. The resulting exchange differences are included in the comprehensive loss.

Assets and liabilities of the Company and its subsidiaries with functional currency other than RMB are translated into RMB at fiscal year-end exchange rates. Income and expense items are translated at average exchange rates during the fiscal year. Translation adjustments arising from these are reported as foreign currency translation adjustments and are shown as accumulated other comprehensive loss.

2.5 Convenience translation

The Group’s business is primarily conducted in PRC and almost all of its revenues are denominated in RMB. However, periodic reports made to shareholders will include current period amounts translated into USD using the then current exchange rates, for the convenience of the readers. Translations of balances in the consolidated balance sheets, consolidated statements of operations and comprehensive loss and consolidated statements of cash flows from RMB into USD as of and for the year ended December 31, 2020 are solely for the convenience of the readers outside PRC and were calculated at the rate of US$1.00=RMB6.525 representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on December 31, 2020. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into USD at that rate on December 31, 2020, or at any other rate.

2.6 Cash and cash equivalents

Cash and cash equivalents primarily consist of cash on hand and cash in bank which is highly liquid and unrestricted as to withdrawal and use.

2.7 Restricted cash

The Group’s restricted cash mainly represents cash received from consumers and reserved in bank supervised accounts for payments to retailers on the on-demand retail platform.

2.8 Short-term investments

Short-term investments include (i) wealth management products issued by commercial banks or other financial institutions with non-guaranteed principal and variable interest rates indexed to the performance of underlying assets within one year; (ii) time deposits with original maturities longer than three months but less than one year. The Group classifies wealth management products as trading securities given the securities are purchased for the purpose of selling them in the near term. Changes in fair values of wealth management products are included in interest income in the consolidated statements of operations and comprehensive loss.

2.9 Accounts receivable, net

Accounts receivable mainly consists of amount due from the Group’s customers, which is recorded net of allowance for doubtful accounts. The Group performs ongoing credit evaluation of its customers, and assesses allowance for doubtful accounts based on the age of the receivables and factors surrounding the credit risk of specific customers.

2.10 Inventories, net

Inventories, consisting of products available for sale, are stated at the lower of cost or market value. Cost of inventory is determined using the weighted average cost method. Adjustments are recorded to write down the cost of inventory to the estimated market value due to slow-moving merchandise and damaged goods, which is determined based upon factors such as historical and forecasted consumer demand, and promotional environment.

2.11 Property and equipment, net

Property and equipment is stated at cost less accumulated depreciation and impairment. Property and equipment is depreciated at rates sufficient to write off its costs less impairment and residual value, if any, over the estimated useful lives on a straight-line basis. The estimated useful lives are as follows:


Category		Estimated useful lives
Computer equipment		3 years
Office facilities		3-5 years
Vehicles		8 years
Software		3-5 years
Leasehold improvement		Over the shorter of the expected useful life or the lease term

Repairs and maintenance costs are charged to operating expenses as incurred, whereas the costs of renewals and betterment that extends 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 costs, accumulated depreciation and impairment with any resulting gain or loss recognized in the other operating income or expenses of consolidated statements of operations and comprehensive loss.

2.12 Intangible assets, net

Intangible assets purchased are recognized and measured at cost upon acquisition. Intangible assets arising from the Group’s acquisition of JDDJ business from JD.com, Inc. ("JD") including Business Cooperation Agreement ("BCA"), Non-Compete Commitment ("NCC"), technology, trademark and domain name are recognized and measured at fair value based on a valuation upon acquisition. The Group made estimates and judgments in determining the fair value of JDDJ business, BCA and NCC with assistance from an independent valuation firm. Following the initial recognition, intangible assets are carried at cost less any accumulated amortization and any accumulated impairment losses. The identifiable intangible assets acquired are amortized on a straight-line basis over the respective useful lives as follows:


Category		Amortization Years
BCA		7
NCC		7
Technology		3.7
Trademark and Domain Name		9-9.7

2.13 Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and liabilities acquired as a result of the Group’s acquisition of JDDJ business from JD occurred in 2016 and there is no change to the carrying amount of goodwill for the years ended December 31, 2019 and 2020. Goodwill is not amortized but is reviewed at least annually for impairment or earlier, if any indication of impairment exists.

In evaluation of goodwill impairment, the Group performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Prior to January 1, 2020, based on the qualitative assessment, if it is more likely than not that the fair value of a reporting unit is less than the carrying amount, the Group performed a two-step test to determine the amount of goodwill impairment. In Step 1, the Group compares the fair value of the reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, the Group performs Step 2 and compares the implied fair value of goodwill with the carrying amount of that goodwill for that reporting unit. An impairment charge equals to the amount by which the carrying amount of goodwill for the reporting unit exceeds the implied fair value of that goodwill is recorded, limited to the amount of goodwill allocated to that reporting unit. Starting from January 1, 2020, the Group adopted ASU 2017-04, which simplifies the accounting for goodwill impairment by eliminating Step 2 from the goodwill impairment test. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, versus determining an implied fair value in Step 2 to measure the impairment loss.

The Group has determined it has only one reporting unit and applied quantitative assessment in its annual goodwill impairment analysis as of December 31 of each year. No goodwill impairment was recorded for 2018, 2019 and 2020 as the fair value of the reporting unit significantly exceeded its carrying value at each assessment date.

Application of a goodwill impairment test requires significant management judgment, including the identification of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and determining the fair value of each reporting unit. The judgment in estimating the fair value of reporting units includes estimating future cash flows, determining appropriate discount rates and making other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit.

2.14 Other non-current assets

Other non-current assets mainly consist of long-term lease deposits, a convertible loan to a private company, and equity investments without readily determinable fair values. Beginning on January 1, 2018, the Group’s equity investments without readily determinable fair values, which do not qualify for NAV practical expedient and over which the Group does not have the ability to exercise significant influence through the investments in common stock or in substance common stock, are accounted for under the measurement alternative upon the adoption of Accounting Standards Update ("ASU") 2016‑01 (the "Measurement Alternative"). Under the Measurement Alternative, the carrying value is measured at cost, less any impairment, plus and minus changes resulting from observable price changes in orderly transactions for identical or similar investments. The Group recognized RMB3,432 and RMB2,000 of impairment losses to write off a loan receivable and an equity investment without a readily determinable fair value, respectively, for the year ended December 31, 2018.

2.15 Fair value measurement

Fair value reflects the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it transacts and considers assumptions that market participants use when pricing the asset or liability.

The Group applies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is as follows:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: Observable, market-based inputs, other than quoted prices, in active markets for identical assets or liabilities.

Level 3: Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

The fair value guidance describes three main approaches to measure 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.

When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates.

2.16 Revenue recognition

The Group derives its revenues principally from merchants’, individual senders’ and retailers’ use of the Group’s core platforms in connection with on-demand retail platform services and on-demand delivery services. Revenue is stated net of value added tax ("VAT"), discounts and return allowances.

Services

The Group arranges for on-demand delivery services to be provided through Dada Now platform where it assists the customer, a merchant or an individual sender, in finding a rider to complete a delivery requested by the customer. The Group concludes that it acts as an agent in these transactions as it is not responsible for fulfilling the promise to provide the delivery services, nor does the Group have the ability to control the related services. The Group does not have the ability to control the services provided by riders due to the following: (i) the Group does not pre-purchase or otherwise obtain control of the riders’ services prior to their transfer to the customers; (ii) the Group does not guarantee an order could be taken by a rider; (iii) the Group cannot direct the riders to accept, decline or disregard a transaction request and (iv) the Group’s platform services do not include the delivery services provided to the customers by the riders. The service fee earned by the Group is the difference between the amount paid by the customer based on an upfront quoted fare and the amount earned by the rider based on expected delivery time, distance and other factors, which are both fixed at the time a transaction is entered into with a customer. The Group may record a loss from a transaction when an upfront quoted fare offered to the customer is less than the amount the Group is committed to paying to the rider. The revenue is recognized on a net basis at the point of delivery of merchandise. The loss on this type of transactions is recorded in operations and support costs in the consolidated statements of operations and comprehensive loss, as it is not related to any other current, previous or future transactions with the customer and in substance, is an expense paid to the rider. The losses included in operations and support costs were RMB133,241, RMB96,131 and RMB76,989 for the years ended December 31, 2018, 2019 and 2020, respectively.

The Group also provides on-demand retail platform services on JDDJ platform. The service revenues primarily consist of commission fees charged to retailers for participating in the Group’s online marketplace, where the Group acts as an agent and its performance obligation is to facilitate the retailers’ online sales of their goods and services through JDDJ. The Group is not primarily obligated to the consumers, does not take inventory risk, and does not have latitude over pricing of the merchandise. Upon successful sales, the Group charges the retailer a fixed rate commission fee based on the sales amount. Commission fee revenues are recognized on a net basis at the point of delivery of merchandise.

In addition, the Group fulfills the delivery needs of retailers on JDDJ and other business customers on Dada Now by utilizing the Group’s network of registered riders on Dada Now. Under this type of services, the Group enters into agreements with retailers and other business customers, which enforce the Group’s acceptance of all the related delivery requests at the prices stipulated in the agreements. The Group has determined that it acts as the principal in these transactions as the Group is primarily responsible for the delivery of merchandise and has the ability to control the related services. The Group has the ability to control the services provided by riders as it is responsible for and guarantees identifying and directing riders that meet the quality criteria stipulated in the agreements to complete the deliveries requested by retailers or other business customers. Additionally, the Group has ultimate control over the amounts charged to the customers. Although in this type of services, the riders still have the ability to accept, decline or disregard a delivery assignment, it is the Group’s responsibility to find a replacement and complete the delivery timely. Revenues resulting from these services are recognized on a gross basis at a fixed rate or a pre-determined amount for each completed delivery, with the amounts paid to the riders recorded in operations and support costs. From September 2020, the Group started to engage truckers to provide freight services to logistics companies or merchants on Dada Now and JDDJ. The Group has determined that it acts as the principal in these freight transactions as it has the ability to control the freight services provided by truckers and primarily responsible for fulfillment of the freight services. The related revenue is included in service revenue under Dada Now as presented in the following table of disaggregation of revenues.

Other services provided by the Group comprise packaging services provided to retailers on JDDJ, online marketing services provided to brand owners on JDDJ, and front-end warehouses services. Revenue is recognized when service is rendered.

Goods Sales

The Group operates its own e-commerce business and sells delivery equipment and other merchandise on Dada Now. The Group also sells merchandise through unmanned retail shelves. Revenue is recognized on a gross basis as the Group is acting as a principal in these transactions, is responsible for fulfilling the promise to provide the specified merchandise and also has pricing discretion. The Group recognizes revenues net of discounts and return allowances when the goods are delivered to the customers.

Incentive programs

Customer incentives

The Group offers various incentive programs to merchants, individual senders and business customers in the form of coupons or volume-based discounts that are recorded as reduction of revenue as the Group does not receive a distinct good or service in consideration.

Rider incentives

The Group offers various incentive programs to riders, primarily in the form of volume-based incentives. The riders are not the Group’s customers as they do not pay for their use of the Group’s platform in any form. Therefore, for transactions where the Group acts as an agent and recognizes revenue on a net basis, the related rider incentives are recorded as a reduction of revenue. The incentive amount in excess of the related revenue is included in operations and support costs. For transactions where the Group acts as a principal and recognizes revenue on a gross basis, the related rider incentives are included in operations and support costs. For the years ended December 31, 2018, 2019 and 2020, incentives to riders recorded in operations and support costs were RMB223,664, RMB192,243 and RMB143,916, respectively, including incentives attributable to transactions where the Group acts as the principal of RMB155,007, RMB158,763 and RMB114,229, respectively.

Consumer incentives

The consumer incentives are offered to promote the Group’s platform in the form of promotion coupon on the JDDJ, which are valid only during a limited period of time. These incentives are provided at the Group’s discretion and are not contractually required by the retailers. These incentives also do not reduce the overall pricing of the services provided by the Group. As the Group has no performance obligation to consumers who are not the Group’s customers, incentives to consumers are recognized as selling and marketing expenses. For the years ended December 31, 2018, 2019 and 2020, consumer incentives that were recorded as selling and marketing expenses were RMB782,479, RMB937,713 and RMB1,166,032, respectively.

All the incentives granted can be categorized into (i) incentives granted concurrent with a purchase transaction and (ii) incentives granted not concurrent with a purchase transaction. When the incentive is granted concurrent with a purchase transaction, expenses or reduction of revenue are accrued, in the most likely amount to be earned, as the related transactions are recorded. Since such incentives are generally earned over a very short period of time, there is limited uncertainty when estimating the expenses to be accrued or variable consideration to be recorded as a reduction of revenue. When the incentive (i.e., a coupon) is granted not concurrent with a purchase transaction, expenses or reduction of revenue are recognized upon the redemption of such incentive.

Disaggregation of revenues

For the years ended December 31, 2018, 2019 and 2020, all of the Group’s revenues were generated in the PRC. The disaggregated revenues by revenue streams were as follows:

Contract balances

The remaining unsatisfied performance obligation as of December 31, 2018, 2019 and 2020 was immaterial.

Timing of revenue recognition may differ from the timing of invoicing customers. Accounts receivable represents amounts invoiced and revenues recognized prior to invoicing when the Group has satisfied its performance obligation and has the unconditional right to payment.

The Group receives advance payments from customers pursuant to the agreements with certain customers before the services or products are provided, which is recorded as advance for marketing services or goods sale included in the accrued expenses and other current liabilities on the consolidated balance sheets. The opening and closing balances of the Group’s advances from customers are as follows:


		Advances from
		Customers
		RMB
Opening Balance as of January 1, 2018		331
Increase, net		3,061
Ending Balance as of December 31, 2018		3,392
Increase, net		11,965
Ending Balance as of December 31, 2019		15,357
Increase, net		10,894
Ending Balance as of December 31, 2020		26,251

The opening balances of RMB331, RMB3,392 and RMB15,357 were recognized in the years ended December 31, 2018, 2019 and 2020, respectively.

Practical expedients and exemptions

The Group elects not to disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

2.17 Operations and support

Operations and support costs primarily consist of (i) riders’ and drivers' remuneration and incentives to fulfil the Group’s delivery orders, (ii) expenses incurred in providing customer and rider care services or the service fee charged by external customer service providers, (iii) expenses charged by outsourced delivery agencies, (iv) transaction fees charged by third-party payment platform, and (v) packaging cost as well as other operations and support costs directly attributed to the Group’s principal operations.

2.18 Selling and marketing

Selling and marketing expenses primarily consist of incentive payments to consumers, advertising and marketing expenses, payroll and related expenses for employees involved in selling and marketing functions, as well as the associated expenses of facilities and equipment, such as depreciation expenses, rental and others. The advertising and marketing expenses amounted to RMB118,829, RMB133,669 and RMB247,858 for the years ended December 31, 2018, 2019 and 2020, respectively.

2.19 Research and development

Research and development expenses primarily consist of technology infrastructure expenses, payroll and related expenses for employees involved in platform development and internal system support, charges for the usage of the server and computer equipment, and editorial content.

2.20 Other operating expenses

Other operating expenses primarily consist of purchase price of merchandise sold on Dada Now and through unmanned retail shelves.

2.21 Leases

As a lessee

The Group leases office space and warehouse facilities in different cities in PRC under non-cancellable operating lease agreements that expire at various dates through October 2024. Prior to January 1, 2020, under ASC Topic 840 "Leases" (ASC 840), each lease was classified at the inception date as either a capital lease or an operating lease. All the Group’s leases were classified as operating lease. The Group’s amounts for periods prior to January 1, 2020 have not been adjusted and continue to be reported in accordance with ASC 840.

Effective January 1, 2020, the Group early adopted ASU No. 2016-02 "Leases" (ASC 842) using the modified retrospective approach. The Group elected the transition package of practical expedients permitted within the standard, which allowed it not to reassess initial direct costs, lease classification, or whether the contracts contain or are leases for any leases that existed prior to January 1, 2020. The Group also elected the short-term lease exemption for all contracts with an original lease term of 12 months or less. Upon the adoption, the Group recognized operating lease right of use ("ROU") assets of RMB125,010 with corresponding lease liabilities of RMB130,127 on the consolidated balance sheets. The operating lease ROU assets include adjustments for prepayments and accrued lease payments. The adoption did not impact the Group's beginning retained earnings as of January 1, 2020, or the Group's prior years' consolidated financial statements.

Under ASC 842, the Group determines whether an arrangement constitutes a lease and records lease liabilities and ROU assets on its consolidated balance sheets at the lease commencement. The Group measures the operating lease liabilities at the commencement date based on the present value of remaining lease payments over the lease term, which is computed using the Group's incremental borrowing rate, an estimated rate the Group would be required to pay for a collateralized borrowing equal to the total lease payments over the lease term. The Group measures the operating lease ROU assets based on the corresponding lease liability adjusted for payments made to the lessor at or before the commencement date, and initial direct costs it incurs under the lease. The Group begins recognizing operating lease expense based on lease payments on a straight-line basis over the lease term after the lessor makes the underlying asset available to the Group. Some of the Group's lease contracts include options to extend the leases for an additional period which has to be agreed with the lessors based on mutual negotiation. After considering the factors that create an economic incentive, the Group does not include renewal option periods in the lease term for which it is not reasonably certain to exercise.

For the years ended December 31, 2018, 2019 and 2020, the Group incurred operating lease costs amounting to RMB40,519, RMB58,713 and RMB47,915 (excluding RMB13,548 for short-term leases not capitalized as ROU assets), respectively.

Supplemental cash flow information related to operating leases included in operating lease assets and liabilities was as follows:


		For the Year Ended
		December 31, 2020
		RMB
Cash payments		48,890
New operating lease assets obtained in exchange for operating lease liabilities		24,688

As of December 31, 2020, the Group's operating leases had a weighted average remaining lease term of 3.12 years and a weighted average discount rate of 4.8%.

Future lease payments under operating leases, excluding short-term leases not capitalized, as of December 31, 2020 were as follows:


		Operating leases

Sublease

The Group subleases warehouses to its merchants on Dada Now platform under operating leases. Prior to January 1, 2020, under ASC 840, the Group, as a sublessor, accounted for the sublease as operating leases as the Group was not relieved of the primary obligation under the original operating leases. After January 1, 2020,in accordance ASC 842, since the Group has not been relieved of the primary obligation of the original operating leases, the Group cannot net the sublease income against its lease payment to calculate the lease liability and ROU asset. The Group has recorded, and will continue to record sub-lease income on a straight-line basis over the term of the sublease. For the years ended December 31, 2018, 2019 and 2020, sublease income of the Group was RMB2,814, RMB13,108, and RMB16,086, respectively, which was included in net revenues in the consolidated statements of operations and comprehensive loss.

2.22 Share-based compensation

The Group accounts for share options granted to employees in accordance with ASC 718, "Stock Compensation". The Group grants options and restricted share units to the Group’s employees, directors, and consultants. In accordance with the guidance, the Group determines whether a share-based compensation should be classified and accounted for as a liability award or an equity award.

Options and restricted share units granted to employees, including directors, vest upon satisfaction of a service condition, which is generally satisfied over four years, and are measured at fair value as of the grant date.

Options granted to non-employees with a service condition are accounted for based on the fair value of the equity instrument issued, as this has been determined to be more reliably measurable. Prior to January 1, 2019, the Group accounted for share-based awards issued to non-employees in accordance with ASC 505‑50, "Equity-Based Payments to Non-Employees", under which the fair value of each option granted to non-employees was estimated on the date of grant using the same option valuation model used for options granted to employees, and then re-measured at each period end. The final measurement date of the fair value of the equity instrument issued was the date on which the non-employee’s performance was completed. On January 1, 2019, the Group adopted ASU 2018‑07, "Compensation-Stock Compensation (Topic 718), Improvements to Non-employee Share-Based Payment Accounting", under which the accounting treatment of the stock compensation payments to non-employees is aligned with the requirements for share-based payments granted to employees. Upon adoption, only liability-classified awards that have not been settled and equity-classified awards for which a measurement date has not been established should be remeasured through a cumulative-effect adjustment to retained earnings as of January 1, 2019. The adoption of this new standard did not have a material impact on the Group’s consolidated financial statements. Therefore, no cumulative-effect adjustment to retained earnings as of January 1, 2019 was made.

Additionally, the Group’s incentive plan provides an exercisability clause where employees or non-employees can only exercise vested options upon the occurrence of the event that the Group’s ordinary shares are publicly traded. The satisfaction of the performance condition becomes probable only upon the completion of the Group’s initial public offering ("IPO"). Therefore, with the Company's completion of IPO in June 2020, the Group has recorded the cumulative share-based compensation expenses for these options.

According to ASC 718, a change in any of the terms or conditions of equity-based awards shall be accounted for as a modification of the award. Therefore, the Group calculates incremental compensation cost of a modification as the excess of the fair value of the modified option over the fair value of the original option immediately before its terms are modified. For vested options, the Group would recognize incremental compensation cost on the date of modification and for unvested options, the Group would recognize, prospectively and over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award.

2.23 Loss per share

Basic loss per share are computed by dividing net loss available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

The Company’s convertible redeemable preferred shares are participating securities as the preferred shares participate in undistributed earnings on an as-if-converted basis. Accordingly, the Group uses the two-class method of computing earnings per share, whereby undistributed net income is allocated on a pro rata basis to each participating share to the extent that each class may share net income for the period. Undistributed net loss is not allocated to preferred shares because they are not contractually obligated to participate in the loss of the Group.

Diluted loss per ordinary share reflects the potential dilution that could occur if securities were exercised or converted into ordinary shares. The Group had convertible redeemable preferred shares, share options, restricted share units and warrants, which could potentially dilute basic earnings per share in the future. To calculate the number of shares for diluted loss per share, the effect of the convertible redeemable preferred shares is computed using the as-if-converted method; the effect of the stock options, restricted share units and warrant are computed using the treasury stock method.

2.24 Government grants

Government grants are primarily referred to the amounts received from various levels of local governments from time to time which are granted for general corporate purposes and to support the Group's ongoing operations in the region. The grants are determined at the discretion of the relevant government authorities and there are no restrictions on their use. The government grants were RMB18,822, RMB72,660 and RMB58,520 for the years ended December 31, 2018, 2019 and 2020, respectively, which were recorded as other operating income in the period the cash is received.

2.25 Taxation

Deferred income taxes are recognized for temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements, net operating loss carry forwards and credits. 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 in accordance with the laws of the relevant taxing authorities. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in which temporary differences are expected to be received or settled. The effect on deferred tax assets and liabilities of changes in tax rates is recognized in the consolidated statements of operations and comprehensive loss in the period of the enactment of the change.

2.26 Segment reporting

The Group uses management approach to determine operating segment. The management approach considers the internal organization and reporting used by the Group’s chief operating decision maker ("CODM") for making decisions in allocation of resource and assessing performance.

The Group’s CODM has been identified as the chief executive officer who reviews the consolidated results of operations when making decisions about allocating resources and assessing performance of the Group. The Group operates and manages its business as a single operating segment.

The Group’s long-lived assets are all located in the PRC and all of the Group’s revenues are derived from the PRC. Therefore, no geographic information is presented.

2.27 Comprehensive loss

Comprehensive loss is defined as the change in equity of the Group during a period arising from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Comprehensive loss is reported in the consolidated statements of operations and comprehensive loss. Accumulated other comprehensive loss, as presented in the accompanying consolidated balance sheets, represents accumulated foreign currency translation adjustments.

2.28 Recent accounting pronouncements

New accounting pronouncements recently adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use asset and lease liability on their balance sheet for all leases with terms beyond twelve months. Effective January 1, 2020, the Group early adopted the requirements of this ASU using the modified retrospective approach with comparative periods continuing to be reported under Topic 840. See Note 2.21 for disclosures required by this ASU.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350), which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. A goodwill impairment will be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The Group early adopted this ASU on January 1, 2020 and the adoption of this ASU did not have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement 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 Group adopted this ASU on January 1, 2020 and the adoption of this ASU did not have a material impact on its consolidated financial statements.

In October 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810), which amends two aspects of the related-party guidance in ASC 810. Specifically, the ASU (1) adds an elective private-company scope exception to the variable interest entity guidance for entities under common control, and (2) amends the guidance for determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in GAAP). The Group early adopted this ASU on January 1, 2020 and the adoption of this ASU does not have a material impact on its consolidated financial statements.

New accounting pronouncements not yet adopted

In June 2016, the FASB issued ASU 2016-13, Credit Losses, Measurement of Credit Losses on Financial Instruments. This ASU provides more useful information about expected credit losses to financial statement users and changes how entities will measure credit losses on financial instruments and timing of when such losses should be recognized. The ASU is effective for the Group for fiscal years beginning after December 15, 2022, including interim periods within that fiscal year. Early adoption is permitted. In May 2019, the FASB issued ASU 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief. This update adds optional transition relief for entities to elect the fair value option for certain financial assets previously measured at amortized cost basis to increase comparability of similar financial assets. The updates should be applied 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 impact on its consolidated financial statements upon adoption.

FAIR VALUE MEASUREMENTS	12 Months Ended
FAIR VALUE MEASUREMENTS	Dec. 31, 2020
FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	3. FAIR VALUE MEASUREMENTS The Group's financial instruments mainly include cash and cash equivalent, restricted cash, short-term investments, accounts receivable, prepayments and other current assets, amount due from and due to related parties, long-term time deposit, accounts payable, short-term loan, payable to riders and drivers, and notes payable. The carrying amounts of these short-term financial instruments approximate their fair value due to their short-term nature. The carrying values of long-term time deposits approximate their fair values as their interest rates are comparable to the prevailing interest rates in the market. As of December 31, 2019 and 2020, the Group's wealth management products that are measured at fair value on a recurring basis subsequent to their initial recognition amounted to RMB242,567 and RMB470,000, respectively. The fair values of wealth management products are measured based on market-based redemption prices which are level 2 inputs provided by the bank that sells such wealth management products. The gains from the change in fair values of wealth management products recorded in interest income in consolidated statements of operations and comprehensive loss are RMB12,263, RMB6,928, and RMB7,855 for the years ended December 31, 2018, 2019 and 2020, respectively. Certain non-financial assets are measured at fair value on a nonrecurring basis, including property and equipment, operating lease right-of-use assets, goodwill and intangible assets and they are recorded at fair value only when impairment is recognized by applying unobservable inputs such as forecasted financial performance and discount rate to the discounted cash flow valuation methodology. During the year ended December 31, 2018, the Group terminated its unmanned retail shelves business and wrote off the related property and equipment of RMB8,481. The Group did not recognize any impairment of property and equipment during the years ended December 31, 2019 and 2020.

SHARE-BASED COMPENSATION

10. SHARE-BASED COMPENSATION

In February 2015, the Group adopted the 2015 Incentive Compensation Plan ("2015 Plan"), which permits the granting of share options, restricted share units and other equity incentives to employees, directors and consultants of the Group. The 2015 plan administrator is the Group’s board of directors. The board may also authorize one or more of the Group’s officers to grant awards under the plan. The Group has authorized 61,605,996 ordinary shares for issuance under the 2015 Plan. The options expire in ten years from the date of grant.

In June 2020, the Group adopted the 2020 Incentive Compensation Plan ("2020 Plan"), which permits the granting of share options, restricted share units and other equity incentives to employees, directors and consultants of the Group. The 2020 plan administrator is the Group's board of directors. The board may also authorize one or more of the Group's officers to grant awards under the plan. The Group has authorized 45,765,386 ordinary shares for issuance under the 2020 Plan. The options expire in ten years from the date of grant.

Under the 2015 Plan and 2020 Plan, options granted to employees vest upon satisfaction of a service condition, which is generally satisfied over four years. Additionally, the 2015 Plan includes a condition where employees can only exercise vested options upon the occurrence of the Company's ordinary shares becoming listed securities, which substantially creates a performance condition ("IPO Condition") that had not been met prior to the Company's IPO. Therefore, the stock compensation expenses related to those options were not recognized until June 5, 2020. The Group recognized RMB131,344 of stock-based compensation expenses for the year ended December 31, 2020.

Under the 2015 Plan, options granted to non-employees are also subject to a four-year service period and the IPO condition. Therefore, the Group did not recognize any stock-based compensation expenses related to such non-employee options until June 2020. The Group recognized RMB34,285 of stock-based compensation expenses for the year ended December 31, 2020. The Group did not grant any share options to non-employees in 2018, 2019 and 2020.

The Group adopted ASU 2018-07 on January 1, 2019 and the stock-based compensation expense for non-employee grants for which a measurement date had not been established was remeasured based on the estimated fair value of the Company's ordinary share of US$2.26 on January 1, 2019.

In determining the fair value of the stock options, the binomial option pricing model was applied. The key assumptions used to determine the fair value of the options at the respective grant dates in 2018, 2019 and 2020 were as follows:


	As of December 31,
	2018		2019		2020
	RMB		RMB		RMB
Expected volatility	36%~38	%	37%~40	%	37%~41	%
Risk-free interest rate (per annum)	3.5%~3.7	%	2.4%~3.6	%	1.7%~2.3	%
Exercise multiples	2.2		2.2		2.2
Expected dividend yield	0.00	%	0.00	%	0.00	%
Fair value of underlying ordinary shares	US$2.01~2.26		US$2.26~3.87		US$4.08~5.79
Fair value of share option	US$1.35~1.59		US$1.59~3.14		US$3.32~5.03

The Group estimated expected volatility by reference to the historical price volatilities of ordinary shares of comparable companies over a period close to the contract term of the options. The Group estimated the risk-free interest rate based on the yield to maturity of U.S. government bonds at grant date with a maturity period close to the contract term of options, adjusted by country risk differential between U.S. and China. As the Group has very limited option exercise history, it estimated exercise multiples based on empirical research on typical employee stock option exercising behavior. The dividend yield was estimated as zero based on the plan to retain profit for corporate expansion and no dividend will be distributed in the near future. Prior to the completion of IPO, the Group determined the fair value of ordinary shares underlying each share option grant based on estimated equity value and allocation of it to each element of its capital structure. The assumptions used in share-based compensation expenses recognition represent the Group’s best estimates, but these estimates involve inherent uncertainties and the application of judgment. If factors change or different assumptions are used, the share-based compensation expenses could be materially different for any period. After IPO, the Company has used the closing price of ordinary shares on the grant date as the fair value of ordinary share. The Group elects to recognize forfeitures when they occur.

The following table summarized the Group’s share option activities under the Option Plans:


			Weighted
		Weighted	Average	Weighted
		Average	Remaining	Average	Aggregate
	Number	Exercise	Contract	Grant Date	Intrinsic
	of Options	Price	life (years)	Fair Value	Value
		US$		US$	US$

Outstanding at December 31, 2020	36,579,248	0.37	5.63	1.13	318,660
Expect to vest at December 31, 2020	9,445,896	0.80	8.68	3.22	78,637
Exercisable at December 31, 2020	27,133,352	0.28	4.94	0.59	240,023

As of December 31, 2020, there was RMB163,060 of total unrecognized compensation expense related to options, which is expected to be recognized over a weighted-average period of 2.63 years.

Restricted share units

On January 20, 2020, the Group granted 15,836,326 restricted share units to employees and non-employees subject to service vesting schedules of one year, four years or six years under the 2015 Plan. The estimated fair value on the grant date of each restricted share unit was US$4.08 (RMB26.62).

On June 5, 2020, the Group granted 100,000 restricted share units to employees, subject to a four-year service vesting schedule under the 2015 Plan. The estimated fair value on the grant date of each restricted share unit was US$4.00 (RMB26.10).

On October 1, 2020, the Group granted 2,059,300 restricted share units to employees, subject to a four-year service vesting schedule under the 2020 Plan. The estimated fair value on the grant date of each restricted share unit was US$6.49 (RMB42.35).

The following table summarized the Group's restricted share unit activities under the 2015 and 2020 Plan:


	Number of
	Restricted Share	Weighted Average
	Units	Grant Date Fair Value
		US$
Unvested at December 31, 2019	2,187,500	2.26
Granted	17,995,626	4.36
Vested	(3,750,000)	3.72
Forfeited	(30,000)	6.49
Unvested at December 31, 2020	16,403,126	4.22
Expected to vest at December 31, 2020	16,403,126	4.22

Restricted share units granted to employees and non-employees are measured based on the closing price of ordinary shares on the grant date and recognized as compensation cost on a straight-line basis over the requisite service period. Total share-based compensation expenses recognized for these restricted share units in 2018, 2019 and 2020 were RMB26,197, RMB38,272 and RMB185,138, respectively. As of December 31, 2020, there were RMB368,252 of unrecognized compensation expenses related to unvested restricted share units which is expected to be recognized over a weighted-average period of 3.98 years.

On April 26, 2016, the Group consummated the acquisition of JDDJ business from JD. The acquisition involved the transfer of certain employees from JD to the Group. These employees were granted with unvested restricted share units by JD (the "JD Employee Awards") when they were employed by JD. The JD Employee Awards which are generally vested annually over six years continued in effect after the acquisition for the employees transferred to the Group, provided that these employees continue their employment with the Group or any subsidiaries of JD.

The Group recognizes the entire cost of JD Employee Awards incurred by JD, the Group’s shareholder, as compensation cost with a corresponding amount as a capital contribution according to ASC 505‑10‑25‑3. Prior to January 1, 2019, the Group re-measured the awards at a fair-value-based amount as of the end of each reporting period until performance was completed. On January 1, 2019, the Group adopted ASU 2018‑07, under which the stock-based compensation for which a measurement date had not been established was re-measured based on the fair value of the JD’s ordinary share of US$20.93 on January 1, 2019. The share-based compensation amounts related to JD’s share were RMB15,195, RMB12,896 and RMB9,311 for the years ended December 31, 2018, 2019 and 2020, respectively. The total amount of unrecognized compensation expenses based on the fair value of unvested restricted share units as of December 31, 2020 was RMB12,489, and is expected to be recognized over a weighted-average period of 1.42 years.

The key terms of the Series A, B, C, D, E and F convertible redeemable preferred shares are as follows:

Conversion

Each holder of preferred shares shall have the right, at such holder’s sole discretion, to convert all or any portion of the preferred shares into ordinary shares on a one-for-one basis at any time. The initial conversion price is the issuance price of preferred shares, subject to adjustment in the event of (1) stock splits, share combinations, share dividends and distribution, recapitalizations and similar events, and (2) issuance of new securities at a price per share less than the conversion price in effect on the date of or immediately prior to such issuance.

(1)

Amount to one hundred percent (100%) of Series B Preferred Shares, Series C Preferred Shares, Series D Preferred Shares, Series E Preferred Shares or Series F Preferred Shares holder (collectively, the "Senior Preferred Shares"), plus all declared but unpaid dividends on such Senior Preferred Shares. If the assets and funds thus distributed among the holders of the Senior Preferred Shares shall be insufficient to permit the payment to such holders of the full Series B, Series C, Series D, Series E and Series F Preference Amount (collectively, the "Senior Preference Amount"), then the entire assets and funds of the Company legally available for distribution shall be distributed ratably among the holders of the Senior Preferred Shares in proportion to the aggregate Senior Preference Amount each such holder is otherwise entitled to receive pursuant to this term;

(2)

If the assets and funds thus distributed among the holders of the Series A Preferred Shares shall be insufficient to permit the payment to such holders of the full Series A Preference Amount, then the entire assets and funds of the Company legally available for distribution to the Series A Preferred Shares shall be distributed ratably among the holders of the Series A Preferred Shares in proportion to the aggregate Series A Preference Amount each such holder is otherwise entitled to receive pursuant to this term;

(3)

If there are any assets or funds remaining after the aggregate Senior Preference Amount and the aggregate Series A Preference Amount has been distributed or paid in full to the applicable holders of Preferred Shares pursuant to term (1) and (2), the remaining assets and funds of the Company available for distribution to the members shall be ratably distributed among all members according to the relative number of ordinary shares held by such member (including the holders of the Series A Preferred Shares, the Series B Preferred Shares, the Series C Preferred Shares, the Series D Preferred Shares, the Series E Preferred Shares and the Series F Preferred Shares).

Dividends

(1)

Each holder of a Preferred Share shall be entitled to receive noncumulative dividend at the rate of eight percent (8%) of the applicable Series A issue price, Series B issue price, Series C issue price, Series D issue price, Series E issue price or Series F issue price as the case may be, per annum for each such share held by such holder, payable out of funds or assets when and as such funds or assets become legally available therefore on parity with each other, prior and in preference to, and satisfied before, any dividend on any other class or series of shares. Such dividends shall be payable only when, as, and if declared by the Board of Directors.

(2)

No dividend or distribution, whether in cash, in property, or in any other shares of the Company, shall be declared, paid, set aside or made with respect to the ordinary shares at any time unless all accrued but unpaid dividends on the Preferred Shares set forth in term (1), if any, have been paid in full, and a distribution is likewise declared, paid, set aside or made, respectively, at the same time with respect to each outstanding Preferred Share such that the dividend or distribution declared, paid, set aside or made to the holder thereof shall be equal to the dividend or distribution that such holder would have received pursuant to this term if such Preferred Share had been converted into ordinary shares immediately prior to the record date for such dividend or distribution, or if no such record date is established, the date such dividend or distribution is made, and if such share then participated in and the holder thereof received such dividend or distribution.

Voting Rights

The holder of a preferred share shall be entitled to such number of votes as equals the whole number of ordinary share into which such holder’s collective preferred shares are convertible immediately after the close of business on the record date of the determination of the Company’s members entitled to vote or, if no such record date is established, at the date such vote is taken or any written consent of the Company’s members is first solicited.

Accounting for the Preferred Shares

The Company has classified the preferred shares as mezzanine equity as these preferred shares are redeemable upon the occurrence of an event not solely within the control of the Company. The holders of the preferred shares have a redemption right and liquidation preference and will not receive the same form of consideration upon the occurrence of the conditional event as the ordinary shareholders would.

The Company recorded the initial carrying amount of the preferred shares with its issuance price, which approximated the issuance date fair value, after the reduction of the issuance cost. The Company uses interest method to accrete the carrying value of the preferred shares to their maximum redemption price at the end of each reporting period. The change in redemption value is recorded against retained earnings, or in the absence of retained earnings, against APIC. Once APIC has been exhausted, additional charges are recorded by increasing the accumulated deficit.

The Company did not identify any derivatives embedded in the preferred shares that were subject to bifurcation and fair value accounting. The Group also determined that there was no beneficial conversion feature attributable to the preferred shares, as the effective conversion price was not less than the fair value of the ordinary shares on the respective commitment date.

The following table summarized the rollforward of the carrying amount of the preferred equity for the years of 2018, 2019, and 2020:

Income Taxes

Cayman Islands

Under the current laws of the Cayman Islands, the Company incorporated in the Cayman Islands are not subject to tax on income or capital gain.

Additionally, the Cayman Islands does not impose a withholding tax on payments of dividends to shareholders.

Hong Kong

Entities incorporated in Hong Kong are subject to Hong Kong profits tax at a rate of 16.5% since January 1, 2010. Operations in Hong Kong have incurred net accumulated operating losses for income tax purpose and no income tax provisions are recorded for the period presented. Under the current Hong Kong Inland Revenue Ordinance, the Group’s subsidiary domiciled in Hong Kong has been subject to a two-tiered profits tax rate regime which is applicable to any year of assessment commencing on or after April 1, 2018. The profits tax rate for the first HK dollar 2,000 of profits of corporations will be lowered to 8.25%, while profits above that amount will continue to be subject to the tax rate of 16.5%.

China

On March 16, 2007, the National People’s Congress of the PRC introduced Corporate Income Tax Law ("CIT Law"), under which Foreign Investment Enterprises ("FIEs") and domestic companies are subject to corporate income tax at a uniform rate of 25%. Certain enterprises benefit from a preferential tax rate of 15% under the CIT Law if they qualify as high and new technology enterprises ("HNTE"). Under such regulation, Dada Glory and Shanghai JDDJ are qualified for HNTE status and are eligible to a reduced income tax rate of 15% for the years ended 2018, 2019 and 2020.

Withholding tax on undistributed dividends

The CIT Law also provides that an enterprise established under the laws of a foreign country or region but whose "de facto management body" is located in the PRC be treated as a resident enterprise for PRC tax purposes and consequently be subject to the PRC income tax at the rate of 25% for its global income. The implementing rules of the CIT Law merely define the location of the "de facto management body" as "the place where the exercising, in substance, of the overall management and control of the production and business operation, personnel, accounting, property, etc., of a non-PRC company is located". Based on a review of surrounding facts and circumstances, the Group does not believe that it is likely that its operations outside of the PRC should be considered a resident enterprise for PRC tax purposes.

The CIT law also imposes a withholding income tax of 10% on dividends distributed by an FIE to its immediate holding company outside of China, if such immediate holding company is considered as a non-resident enterprise without any establishment or place within China or if the received dividends have no connection with the establishment or place of such immediate holding company within China, unless such immediate holding company’s jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. The Cayman Islands, where the Company is incorporated, does not have such tax treaty with China. According to the arrangement between the Mainland China and Hong Kong Special Administrative Region on the Avoidance of Double Taxation and Prevention of Fiscal Evasion in August 2006, dividends paid by an FIE in China to its immediate holding company in Hong Kong will be subject to withholding tax at a rate of no more than 5% (if the foreign investor owns directly at least 25% of the shares of the FIE).The Company did not record any dividend withholding tax, as it has no retained earnings for any of the periods presented.

As of December 31, 2018, 2019 and 2020, the Group had net operating loss carry forwards of approximately RMB5,537,754, RMB7,222,966 and RMB8,625,584, respectively, which arose from the subsidiaries, VIE and VIE’s subsidiaries established in the PRC. The loss carry forwards will expire during the period from 2021 to 2029.

The Group believes that it is more likely than not that the net accumulated operating losses and other deferred tax assets will not be utilized in the future based on an evaluation of a variety of factors including the Group’s operating history, accumulated deficit, existence of taxable temporary differences and reversal periods. Therefore, the Group provided full valuation allowances for the deferred tax assets as of December 31, 2019 and 2020, respectively.

According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of income taxes is due to computational errors made by the taxpayer. The statute of limitations will be extended to five years under special circumstances, which are not clearly defined, but an underpayment of income tax liability exceeding RMB100 is specifically listed as a special circumstance. In the case of a transfer pricing related adjustment, the statute of limitations is ten years. There is no statute of limitations in the case of tax evasion. The Group’s PRC subsidiaries are therefore subject to examination by the PRC tax authorities from 2015 through 2020 on non-transfer pricing matters and transfer pricing matters.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

- Definition

Tabular disclosure of the significant judgments and assumptions made in determining whether a variable interest (as defined) held by the entity requires the variable interest entity (VIE) (as defined) to be consolidated and (or) disclose information about its involvement with the VIE, individually or in aggregate (as applicable); the nature of restrictions, if any, on the consolidated VIE's assets and on the settlement of its liabilities reported by an entity in its statement of financial position, including the carrying amounts of such assets and liabilities; the nature of, and changes in, the risks associated with involvement in the VIE; how involvement with the VIE affects the entity's financial position, financial performance, and cash flows; the lack of recourse if creditors (or beneficial interest holders) of the consolidated VIE have no recourse to the general credit of the primary beneficiary (if applicable); the terms of arrangements, giving consideration to both explicit arrangements and implicit variable interests, if any, that could require the entity to provide financial support to the VIE, including events or circumstances that could expose the entity to a loss; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; the significant factors considered and judgments made in determining that the power to direct the activities of a VIE that most significantly impact the VIE's economic performance are shared (as defined); the carrying amounts and classification of assets and liabilities of the VIE included in the statement of financial position; the entity's maximum exposure to loss, if any, as a result of its involvement with the VIE, including how the maximum exposure is determined and significant sources of the entity's exposure to the VIE; a comparison of the carrying amounts of the assets and liabilities and the entity's maximum exposure to loss; information about any liquidity arrangements, guarantees, and (or) other commitments by third parties that may affect the fair value or risk of the entity's variable interest in the VIE; whether or not the entity has provided financial support or other support (explicitly or implicitly) to the VIE that it was not previously contractually required to provide or whether the entity intends to provide that support, including the type and amount of the support and the primary reasons for providing the support; and supplemental information the entity determines necessary to provide.
