Summary of principal accounting policies

Basis of presentation

(a) Basis of presentation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for the periods presented.

The accompanying consolidated financial statements have been prepared on a going concern basis.

Consolidation

(b) Consolidation

The Company’s consolidated financial statements include the financial statements of the Company, its subsidiaries and the consolidated VIEs for which the Company is the primary beneficiary.

A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power, has the power to appoint or remove the majority of the members of the board of directors, to cast a majority of votes at the meeting of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

A consolidated VIE is an entity in which the Company, or its subsidiaries, through contractual arrangements, bears the risks of, and enjoys the rewards normally associated with, ownership of the entity, and therefore the Company or its subsidiaries are the primary beneficiary of the entity.

All transactions and balances among the Company, its subsidiaries and the consolidated VIEs have been eliminated upon consolidation.

Use of estimates

The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, measurement and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amount of expenses during the reporting periods. 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 include, allowance for doubtful accounts, useful lives of property, equipment and software, impairment of long-lived assets, internal rate of return associated with the capital lease, valuation and recognition of share-based compensation arrangements, convertible redeemable preferred shares and warrant liabilities, capitalized software development cost and valuation allowance of deferred tax assets.

Functional currency and foreign currency translation

(d) Functional currency and foreign currency translation

An entity’s functional currency is the currency of the primary economic environment in which it operates, normally that is the currency of the environment in which it primarily generates and expends cash and is determined by various indicators, including but not limited to cash flow, sales price, sales market, expenses, financing and intercompany transactions and arrangements. The functional currency of the Company, its consolidated VIEs in BVI and subsidiary in Hong Kong is the United States dollar (US$). The Company’s subsidiaries and consolidated VIEs in PRC use Renminbi (“RMB”) as their functional currency. The determination of the respective functional currency is based on the criteria of ASC 830, Foreign Currency Matters.

Transactions denominated in currencies other than functional currencies are translated into functional currencies at the exchange rates quoted by the People’s Bank of China (the “PBOC”) prevailing at the dates of the transactions. Gains and losses resulting from foreign currency transactions are included in net income. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currencies using the applicable exchange rates quoted by the PBOC at the balance sheet dates. All such exchange gains and losses are included in net income.

The reporting currency of the Group is RMB. Assets and liabilities are translated at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenues, expenses, gains and losses are translated using the average rate for the period. Translation adjustments are reported as accumulated comprehensive income/(loss) and are shown as a separate component of other comprehensive income/(loss) in the consolidated statements of comprehensive income/(loss).

Fair value measurements

(e) Fair value measurements

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

The established fair value hierarchy 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 three levels of inputs may be used to measure fair value include:

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

The Group’s financial instruments include cash and cash equivalents, restricted cash, short-term investments, accounts receivable, amounts due from a related party — current, prepayments and other current assets, short-term borrowings, accounts and notes payable, amounts due to related parties — current and non-current, financing payable — current and non-current and accruals and other current liabilities. Except for short-term investments which are measured at fair value, the carrying values of the other financial instruments approximated their fair values due to the short-term maturity of these instruments. Certain short-term investments in financial products and securities classified within Level 2 are valued using directly or indirectly observable inputs in the marketplace.

The Group’s assets and liabilities measured at fair value on a recurring basis are summarized below:


	Fair Value Measurement
	Using Significant
	Other Observable Inputs
	(Level 2)
	As of December 31,
	2020	2021
	RMB	RMB
Short-term investments	170,552	1,418,721

Refer to Note 12 for roll forward of level 3 financial instruments and key assumptions used by the Group in estimating the fair value of warrant liabilities.

Convenience translation

(f) Convenience translation

Translations of the consolidated balance sheets, the consolidated statements of comprehensive income/(loss) and the consolidated statements of cash flows from RMB into US$ as of and for the year ended December 31, 2021 are solely for the convenience of the readers and were calculated at the rate of US$1.00=RMB6.3726, representing the certificated exchange rate published by the Federal Reserve Board as of December 31, 2021. No representation is made that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2021, or at any other rate.

Cash and cash equivalents

(g) Cash and cash equivalents

Cash and cash equivalents include cash on hand and demand deposits placed with banks and third-party payment processors, which are unrestricted from withdrawal or use, that have original maturities of three months or less at the time of purchase and are readily convertible to known amounts of cash.

Restricted cash

(h) Restricted cash

Cash that is restricted from withdrawal for use or pledged as security is reported separately on the face of the consolidated balance sheets. The Group’s restricted cash mainly represents the deposits held in designated bank accounts for issuance of bank acceptance notes and letter of guarantee. The Group adopted ASU No. 2016-18, Statement of Cash Flows: Restricted Cash (Topic 230) for all period presented.

Cash and cash equivalents and restricted cash as reported in the consolidated statements of cash flows are presented separately on consolidated balance sheets as follows:


	As of December 31,
	2020	2021
	RMB	RMB
Cash and cash equivalents	1,252,493	1,296,924
Restricted cash	51,008	19,671
Long-term restricted cash	—	20,000
Total	1,303,501	1,336,595

Short-term investments

(i) Short-term investments

Short-term investments are comprised of investments in financial products issued by banks or other financial institutions, which contain a fixed or variable interest rate and with original maturities between one month and one year. Such investments are generally not permitted to be redeemed prior to the maturity or are subject to penalties for redemption prior to maturity. These investments are stated at fair value. Changes in the fair value are reflected in the consolidated statements of comprehensive income/(loss).

Accounts receivable, net

(j) Accounts receivable, net

The Group’s accounts receivable mainly consist of amounts due from the customers less an allowance for doubtful accounts. The Group reviews accounts receivable on a periodic basis and makes allowances when there is doubt as to the collectability of individual balances. The Group determines the allowance for doubtful accounts on general basis taking into consideration various factors including but not limited to historical collection experience and credit worthiness of the customers as well as the age of the individual receivables balance. The facts and circumstances of each account may require the Group to use substantial judgment in assessing its collectability. For the years ended December 31, 2019, 2020 and 2021, the Group recognized a provision for doubtful accounts of RMB7,063, RMB5,302 and RMB3,206, respectively.

The following table summarized the details of the Group’s allowance for doubtful accounts:


	As of December 31,
	2019	2020	2021
	RMB	RMB	RMB
Balance at the beginning of year	440	5,025	3,268
Provision for doubtful accounts	7,063	5,302	3,206
Write-offs	(2,478)	(7,059)	(488)
Balance at the end of year	5,025	3,268	5,986

Inventories, net

(k) Inventories, net

Inventories, consisting of products for sale, are stated at the lower of cost or net realizable 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 net realizable value due to slow-moving merchandises and damaged goods, which is dependent upon factors such as historical and forecasted consumer demand, and promotional environment. The Company takes ownership, risks and rewards of the products purchased.

Property, equipment and software, net

(l) Property, equipment and software, net


Cabinets		5 years
Power banks		3 years
Computer and electronic equipment		3 years
Production tools		5 years
Software		10 years
Others		3 to 5 years
Leasehold improvements		Shorter of the estimated useful lives or the lease term

Property, equipment and software are stated at cost less accumulated depreciation and impairment. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives.

The Group purchases certain raw materials and components directly from suppliers and outsources the manufacturing to the assembly partners. Raw materials, components and all other direct costs that are related to the production of power banks and cabinets under construction and incurred in connection with bringing the assets to their intended use are capitalized as construction in progress. Construction in progress is transferred to power banks and cabinets and depreciation commences when the asset is ready for its intended use.

Expenditures for maintenance and repairs are expensed as incurred. Gain or loss on the disposal of property, equipment and software is the difference between the net sales proceeds and the carrying amount of the relevant assets and is recognized in the consolidated statements of comprehensive income/(loss).

The Group’s power banks can be used either for rental in relation to the mobile device charging business or for sale, at the discretion of the users. The Group initially records the power bank as property and equipment based on the usage pattern of its users who primarily opt to rent the power banks. When the users elect to purchase power banks, the pertinent power banks are reclassified to the inventory at the net carrying value and are recognized as cost of revenues upon the transfer of power banks to users. As of December 31, 2020 and 2021, all power banks that were elected for purchase by the users had been transferred to the users. For the years ended December 31, 2019, 2020 and 2021, the Group recognized cost of revenue in connection with the power bank sales with the amount of RMB31,960, RMB31,856 and RMB27,956, respectively.

Capitalized Software Development Cost

(m) Capitalized Software Development Cost

The Group capitalizes the direct development costs associated with internal-used software in accordance with ASC 350-40, “Internal-use software”, which requires the capitalization of costs relating to certain activities of developing internal-use software that occur during the application development stage. Costs capitalized mainly include payroll and payroll-related costs for employees incurred during the application development stage of the internal-use software projects. Capitalized internal-use software costs are stated at cost less accumulated amortization and the amount is included in “property and equipment, net” on the consolidated balance sheets, with an estimated useful life of three years. Software development cost capitalized amounted to nil, nil and RMB7,922 for the years ended December 31, 2019, 2020 and 2021, respectively. The amortization expense for capitalized software costs amounted to nil, nil and RMB1,280 for the years ended December 31, 2019, 2020 and 2021, respectively. As of December 31, 2020 and 2021, the carrying amount of capitalized internal use software development costs was nil and RMB6,642, respectively.

Impairment of long-lived assets

(n) Impairment of long-lived assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of any impairment loss for long-lived assets that management expects to hold and use is based on the amount the carrying value exceeds the fair value of the asset.

When impairment is recognized, the adjusted carrying amount of the underlying fixed assets becomes their carrying value. The new cost basis is depreciated over the remaining useful lives of the assets. For all periods presented, there was no impairment of any of the Group’s long-lived assets.

Revenue recognition

(o) Revenue recognition

The Group’s revenues are primarily derived from (i) mobile device charging business, (ii) power bank sales, and (iii) others. Revenue recognition policies for each type of revenue stream are as follows:

Mobile device charging business

The Group deploys its equipment, including cabinets with power banks, in highly frequented points of interest, such as entertainment venues, restaurants, shopping centers, hotels, transportation hubs and public spaces, etc., which are operated by its location partners. Individual customers can scan the QR code on the cabinets with their mobile devices to place an order to use a power bank. A deposit is generally required for each order placed by the users except for users who have qualified credit scores at WeChat or Alipay. The deposit is refunded to users when they return the power banks. The Group records the deposit in accruals and other current liabilities. As provided in the customer agreement, if the power banks are not returned by the users after a certain period of time, the deposit will be kept by the Group to settle their usage of the power banks. The Group recognizes such deposit as revenue from the mobile device charging business.

The Group earns its revenue from the mobile device charging business from the rental fees it receives from the customers, which are a function of the hourly rate determined by the Group and the period of time for which the customers use the power banks. The Group collects fees directly from its customers through third party payment processors, such as WeChat and Alipay, generally upon the return of the power bank. As individual customers have the right to use a specific power bank for a period of time to charge their mobile devices, the arrangements with the individual customers constitute a lease and the revenue for the mobile device charging business is recognized under ASC 840, “Leases” (“ASC 840”). The revenue generated from the mobile device charging business is recognized as contingent rental revenue which is accrued during the rental period of the power banks, in accordance with ASC 840.

The mobile device charging business is operated under a direct model or a network partner model as follows:

●

Under the direct model, the Group identifies and negotiates with location partners directly and pays location partners commissions based on a certain percentage of the revenue the Group generates from the equipment placed in location partners’ venues. In some cases, the Company pays the location partners entry fees or prepaid commissions for placement of the Group’s equipment. The amortization of entry fees and commissions paid to the location partners are presented as sales and marketing expenses; and

●

Under the network partner model, the Group collaborates with network partners by leveraging their local business network to expand its business. The network partners are engaged to identify the points of interest and negotiate with the location partners for deployment of the equipment. The Group is obligated to pay commissions to network partners based on a certain percentage of the revenue the Group generates from the equipment placed by the network partners. The commissions paid to location partners or network partners are presented as sales and marketing expenses.

Transaction with network partners - sales of the cabinets

Under the network partner model, the Group sells the cabinets to majority of network partners, but retains all the output derived from the cabinets, whose only potential use is to store, charge, and process the Group’s proprietary power banks, for an indefinite period. The Group has determined that this right of use should be accounted for as an embedded lease for the estimated useful life of the cabinets. Since the embedded lease of the cabinets would be classified as a capital lease, the Group accounts for the proceeds from the network partners as a financing transaction rather than as a sale of the cabinets.

Therefore, the cabinets continue to be recognized as the Group’s equipment and are depreciated over their useful lives (Note 5). The cash received from the network partners for the cabinets is initially recognized as financial liabilities and the liability is subsequently accreted over the useful life of the cabinets based on the estimated effective rate of return implicit in the lease, with interest expense being recognized. The effective interest rate is estimated based on the projected variable lease repayment amounts that have been bifurcated from the estimated commissions to be paid to the network partners during the useful life of the cabinets based on their relative standalone selling prices. The financial liabilities are settled when payments are made to the network partners. The financial liabilities that are expected to be settled over one year from the balance sheet date are presented as long-term liabilities.

The Group regularly evaluates the effective interest rate against the actual lease repayments and prospectively adjusts the effective interest rate as necessary. For the periods presented, there was no material change in the effective interest rate. For the years ended December 31, 2019, 2020 and 2021, the weighted average effective interest rate was 20%, 23% and 24%, respectively.

The roll forward of the aggregated financing payables for both current and non-current are as below:


	Year Ended December 31,

Transaction with network partners – upfront fee

Since 2021, the Group entered into network partners agreements with certain network partners under which, instead of purchasing the cabinets from the Group, the network partners agree to pay a pre-agreed fixed upfront fee to the Group to become its network partners. During the contractual period, the network partners are entitled to the commission from the Group based on a certain percentage of the revenue the Group generates from the equipment placed by the network partners. The upfront fee is recorded as liability when collected and is amortized on a straight-line basis over the contractual term of the network partner agreement as the deduction of the commission to the to the network partners. For the year ended December 31, 2021, the upfront fees agreed under such arrangements were RMB158,176, among which RMB14,586 was amortized as the reduction to the sales and marketing expenses.

The Group sells certain merchandises through online platform. The Group recognizes revenue net of discounts and return allowance when the merchandises are delivered and control passes to the customers.

Generally, revenues are recorded at the gross sales price because the Group controls the specified goods or services, and is the primary obligor in a transaction, is subject to substantial inventory risk, and has latitude in establishing prices.

(t) Employee benefits

The Company’s subsidiaries and the consolidated VIE in China participate in a government mandated, multi-employer, defined contribution plan, pursuant to which certain retirement, medical, housing and other welfare benefits are provided to employees. Chinese labor laws require the entities incorporated in China to pay to the local labor bureau a monthly contribution at a stated contribution rate based on the monthly basic compensation of qualified employees.

VAT refund is recognized as other operating income upon receipt as further performance by the Group is not required. For the years ended December 31, 2019, 2020 and 2021, government subsidies were RMB12,349, RMB24,790 and RMB29,956, respectively.

Share-based compensation

(v) Share-based compensation

The Company follows ASC 718, “Compensation — Stock Compensation” to determine whether share-based awards should be classified and accounted for as a liability award or equity award. The Company granted restricted shares, RSUs and share options to the Company’s founders, employees and external consultants, which are classified as equity awards and recognized in the consolidated financial statements based on their grant date fair values.

Share-based compensation awards are measured at the grant date fair value of the awards and recognized as expenses a) immediately at grant date if no vesting conditions are required; or b) for awards granted with only service conditions, using the straight-line vesting method, over the vesting period.

Share-based compensation in relation to the restricted shares and RSUs is measured based on the fair market value of the Group’s ordinary shares at the grant date of the award. Prior to the listing, estimation of the fair value of the Group’s ordinary shares involves significant assumptions that might not be observable in the market, and a number of complex and subjective variables, including discount rate, and subjective judgments regarding the Group’s projected financial and operating results, its unique business risks, the liquidity of its ordinary shares and its operating history and prospects at the time the grants are made. In addition, the binomial option-pricing model is used to measure the value of share options. The determination of the fair value is affected by the fair value of the ordinary shares as well as assumptions including the expected share price volatility, actual and projected employee and non-employee share option exercise behavior, risk-free interest rates and expected dividends. The fair value of these awards was determined taking into account independent valuation advice.

The modifications of the terms or conditions of the shared-based award are treated as an exchange of the original award for a new award. The incremental compensation expense is equal to the excess of the fair value of the modified award immediately after the modification over the fair value of the original award immediately before the modification. For awards already vested as of the modification date, the Company immediately recognized the incremental value as compensation expenses. For awards still unvested as of the modification date, the incremental compensation expenses are recognized over the remaining service period of these awards.

In accordance with ASU 2016-09, the Group makes an entity-wide accounting policy election to account for forfeitures when they occur.

Leases

(w) Leases

Leases are classified at the inception date as either a capital lease or an operating lease. 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.

All other leases are accounted for as operating leases wherein rental payments are expensed as incurred. Payments made under operating leases, net of any incentives received by the Group from the lessor, are charged to the consolidated statements of comprehensive income/(loss) on a straight-line basis over the lease periods. For the years ended December 31, 2019, 2020 and 2021, operating lease expenses recorded in the consolidated statements of comprehensive income/(loss) amounted to RMB18,585, RMB34,682 and RMB41,902, respectively.

Income tax

(x) Income tax

Current income taxes are provided on the basis of net income for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for income tax purposes, in accordance with the regulations of the relevant tax jurisdictions. Deferred income taxes are provided using the liability method. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purposes. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive income/(loss) in the period of change. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized.

Uncertain tax positions

ASC 740, Tax provision prescribes a more likely than not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Guidance was also provided on de-recognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures. Significant judgment is required in evaluating the Group’s uncertain tax positions and determining its provision for income taxes. The Group recognizes interests and penalties, if any, under accrued expenses and other current liabilities on its consolidated balance sheets and under income tax expenses in its consolidated statements of comprehensive income/(loss). As of December 31, 2020 and 2021, the Group did not have any unrecognized uncertain tax position, or any interest or penalties associated with tax positions.

In order to assess uncertain tax positions, the Group applies a more likely than not threshold and a two-step approach for the tax position measurement and financial statement recognition. Under the two-step approach, the first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement.

Statutory reserves

(y) Statutory reserves

In accordance with China’s Company Laws, the Company’s subsidiaries and consolidated VIEs in PRC must make appropriations from their after-tax profit (as determined under the Accounting Standards for Business Enterprises as promulgated by the Ministry of Finance of the People’s Republic of China (“PRC GAAP”)) to non-distributable reserve funds including (i) statutory surplus fund and (ii) discretionary surplus fund. The appropriation to the statutory surplus fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the respective company. Appropriation to the discretionary surplus fund is made at the discretion of the respective company.

Pursuant to the laws applicable to China’s Foreign Investment Enterprises, the Company’s subsidiary that is a foreign investment enterprise in China has to make appropriations from its after-tax profit (as determined under PRC GAAP) to reserve funds including (i) general reserve fund, (ii) enterprise expansion fund and (iii) staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the respective company. Appropriations to the other two reserve funds are at the respective companies’ discretion.

For the years ended December 31, 2019, 2020 and 2021, the Group has provided RMB11,915, RMB 4,678 and nil appropriations to statutory surplus fund, respectively.

Comprehensive income/(loss)

(z) Comprehensive income/(loss)

Comprehensive income/(loss) is defined as the change in equity of the Group during the period from transactions and other events and circumstances excluding transactions resulting from investments from owners and distributions to owners. For the periods presented, the Group’s comprehensive income/(loss) includes net income and other comprehensive income/(loss), which mainly consists of the foreign currency translation adjustment that have been excluded from the determination of net income. Accumulated other comprehensive income/(loss), as presented on the accompanying consolidated balance sheets, consists of cumulative foreign currency translation adjustments.

Income/(loss) per share

(aa) Income/(loss) per share

Basic income/(loss) per share is computed by dividing net income/(loss) attributable to holders of ordinary shares 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 common shares and other participating securities base on their participating rights. Diluted net income/(loss) per share reflects the potential dilution that could occur if securities to issue ordinary shares were exercised. The dilutive effect of outstanding share-based awards is reflected in the diluted net income/(loss) per share by application of the if-converted method and treasury stock method, respectively. Dilutive equivalent shares are excluded from the computation of diluted net income/(loss) per share if their effects would be anti-dilutive.

Dividends

(ab) Dividends

Dividends are recognized when declared. No dividends were declared for the years ended December 31, 2019, 2020 and 2021.

Treasury shares

(ac) Treasury shares

Treasury shares for the years ended December 31, 2019 and 2020 represents ordinary shares issued to the Company’s consolidated VIEs for the RSUs scheme. Refer to Note 13(b) for details. On September 28, 2021, the Company’s board of directors authorized a share repurchase program under which the Company was authorized to repurchase up to US$50 million worth of the Company’s shares over the next 12 months (the “Share Repurchase Program”). The share repurchase programs permitted the Company to purchase shares from time to time on the open market at prevailing market prices, in privately negotiated transactions, in block trades and/or through other legally permissible means, depending on market conditions and in accordance with applicable rules and regulations. The repurchased shares were accounted for under the cost method and presented as “treasury stock” in equity on the Group’s consolidated balance sheets.

Segment reporting

(ad) Segment reporting

In accordance with ASC 280, Segment Reporting, the Group’s chief operating decision maker, the Chief Executive Officer, reviews the consolidated results when making decisions about allocating resources and assessing performance of the Group as a whole and hence, the Group has only one reportable segment.

The Group does not distinguish between markets or segments for the purpose of internal reporting. The Group’s long-lived assets are substantially all located in the PRC and substantially all the Group’s revenues are derived from within the PRC, therefore, no geographical segments are presented.

Recent accounting pronouncements

(ae) Recent accounting pronouncements

The Company qualifies as an “emerging growth company”, or EGC, pursuant to the Jumpstart Our Business Startups Act of 2012, as amended, or the JOBS Act. As an EGC, the Company can elect to not adopt any new or revised financial accounting standards until such date that a private company is otherwise required to comply with such new or revised accounting standards. The Company adopts the following standards based on extended transition period provided to private companies or early adopts as necessary as permitted by the respective standards.

In February 2016, the FASB issued ASU No. 2016-02 “Leases (Topic 842)” (“ASU 201602”). Under the new guidance, lessees will be required to recognize a lease liability and a right-of use asset for each of its leases (other than leases that meet the definition of a short-term lease). Leases will be classified as either operating or finance. The update also expands the required quantitative and qualitative disclosures for leases. The Group will adopt this new guidance for the year ended December 31, 2022 by using the modified retrospective transition method with the optional transition that allows for a cumulative-effect adjustment to the opening balance of retained earnings recorded on January 1, 2022. Upon the adoption, the Group estimated approximately RMB10,000 to RMB15,000 would be recognized as total right-of-use assets and total lease liabilities on the Group’s consolidated balance sheet as of January 1, 2022. Other than disclosed, the Group does not expect the new standard to have a material impact on the Group’s remaining consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements. This ASU update on the measurement of credit losses for certain financial assets measured at amortized cost and available-for-sale debt securities. In April 2019, the FASB issued ASU 2019-04 "Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments." For financial assets measured at amortized cost, this update requires an entity to (1) estimate its lifetime expected credit losses upon recognition of the financial assets and establish an allowance to present the net amount expected to be collected, (2) recognize this allowance and changes in the allowance during subsequent periods through net income and (3) consider relevant information about past events, current conditions and reasonable and supportable forecasts in assessing the lifetime expected credit losses. For available-for-sale debt securities, this update made several targeted amendments to the existing other-than-temporary impairment model, including (1) requiring disclosure of the allowance for credit losses, (2) allowing reversals of the previously recognized credit losses until the entity has the intent to sell, is more-likely-than-not required to sell the securities or the maturity of the securities, (3) limiting impairment to the difference between the amortized cost basis and fair value and (4) not allowing entities to consider the length of time that fair value has been less than amortized cost as a factor in evaluating whether a credit loss exists. For the Group, ASU 2016-13 is effective for fiscal years and interim periods within those years beginning after December 15, 2022, with early adoption permitted. The Group is in the process of evaluating the impact of this accounting standard on its consolidated financial statements.

Smart Share CGY and Smart Share Brothers

In May 2017, Smart Share CGY and Smart Share Brothers were established by one of the Company’s founders, to facilitate the adoption of the Company’s restricted share units (“RSUs”) scheme for the Company’s employees and external consultants. Upon the inception of Smart Share CGY and Smart Share Brothers, the Company entered into the management agreements with Smart Share CGY, Smart Share Brothers and their shareholder. Pursuant to the management agreements, the shareholder of Smart Share CGY and Smart Share Brothers irrevocably appoints the Company or its designated person to exercise the shareholder and director rights in Smart Share CGY and Smart Share Brothers; the shareholder of Smart Share CGY and Smart Share Brothers shall not transfer or pledge his shares in Smart Share CGY and Smart Share Brothers without the consent from the Company; the RSUs scheme of Smart Share CGY and Smart Share Brothers shall be administered by the board of directors of the Company; and all profit and loss of Smart Share CGY and Smart Share Brothers shall be entitled to and assumed by the Company. The management agreements shall be effective until the Company, Smart Share CGY, Smart Share Brothers and their shareholder mutually agree to terminate.

Accordingly, the management agreements provide the Company with the power to direct the activities that most significantly impact Smart Share CGY and Smart Share Brothers’ economic performance and the obligation to absorb the risks and receive the rewards normally associated with the ownership of Smart Share CGY and Smart Share Brothers. Therefore, management concluded that Smart Share CGY and Smart Share Brothers are consolidated VIEs of the Company, of which the Company is the ultimate primary beneficiary.

The term of this agreement remains valid for a period of 10 years and can be extended at Zhixiang WFOE’s discretion. Zhixiang WFOE may terminate the agreement unilaterally with a 30-day prior written notice. For the years ended December 31, 2019, 2020 and 2021, the consultancy and service fees charged by Zhixiang WFOE were RMB168,451, RMB276,577 and nil, respectively.

Equity Interest Pledge Agreement

Pursuant to the equity interest pledge agreement, the Nominee Shareholders have pledged 100% equity interests in Shanghai Zhixiang to Zhixiang WFOE as security for repayment obligations of any and all due payments, including but not limited to the consultancy and service fees due from Shanghai Zhixiang to Zhixiang WFOE under the exclusive business cooperation agreement. During the term of the equity interest pledge agreement, the Nominee Shareholders undertake that, without the prior written consent of Zhixiang WFOE, they will not transfer, or create or allow any encumbrance on the pledged equity interests, except as otherwise provided in the exclusive option agreement. If any of the specified events of default occurs, Zhixiang WFOE will have the right to request repayment of all due and payable payments, and/or transfer, auction or sale of all or part of the pledged equity interests in Shanghai Zhixiang and will have priority in receiving the proceeds from such disposal. Zhixiang WFOE may transfer all or any of its rights and obligations under the exclusive business cooperation agreement to its designee(s) at any time. The term of the agreement is 10 years and shall be extended if the term of the exclusive business cooperation agreement is extended. Since the initial paid-in capital of Shanghai Zhixiang was contributed by the Nominee Shareholders without being financed by the Company and the equity interest pledge agreement did not transfer the legal title of the pledged equity interest to the Company under PRC law, the Nominee Shareholders continue to have legal ownership of the paid-in capital of Shanghai Zhixiang. Accordingly, the initial paid-in capital of Shanghai Zhixiang amounted to RMB1,000 was recorded as other non-current liabilities to the Nominee Shareholders of Shanghai Zhixiang.

Exclusive Option Agreement

Pursuant to the exclusive option agreement, the Nominee Shareholders have irrevocably granted Zhixiang WFOE, to the extent permitted by PRC law, an irrevocable and exclusive right to purchase, or designate a third-party to purchase, all or any part of their equity interests at any time or from time to time at a purchase price equal to the lowest price permissible by PRC law. The option term remains valid for a period of 10 years and can be extended at Zhixiang WFOE’s discretion. Shanghai Zhixiang and their Nominee Shareholders have agreed that without prior written consent of the Zhixiang WFOE, their respective Nominee Shareholders cannot sell, transfer, pledge or dispose their equity interests, and Shanghai Zhixiang cannot sell, transfer, pledge or dispose, but not limited to, the equity interests and significant businesses. Also as agreed, Shanghai Zhixiang cannot change capitalization structure of Shanghai Zhixiang and cannot enter into any loan or investment agreements.

Proxy Agreement

Pursuant to the irrevocable proxy agreement, each of the Nominee Shareholders irrevocably authorized Zhixiang WFOE to act on their respective behalf as sole proxy attorney, to the extent permitted by law, to exercise all rights concerning all the equity interest held by each of them in Shanghai Zhixiang, including but not limited to proposing to convene or attend shareholder meetings, attending shareholder meetings, signing resolutions and minutes of such meetings, exercising all the rights as shareholders in such meeting (including but not limited to voting rights, nomination rights and appointment rights), the right to receive dividends and the right to sell, transfer, pledge or dispose of all the equity held in part or in whole, and exercising all other rights as shareholders allowable under PRC law and the memorandum and articles of our company.

Exclusive Assets Subscription Agreement

Pursuant to the exclusive assets subscription agreement, Shanghai Zhixiang has irrevocably granted Zhixiang WFOE, to the extent permitted by PRC law, an irrevocable and exclusive right to purchase, or designate a third-party to purchase, all the intellectual property rights and all the other assets currently owned or to be owned by Shanghai Zhixiang at any time at a purchase price equal to the lowest price permissible by PRC law. Shanghai Zhixiang further undertakes that, without Zhixiang WFOE’s prior written consent, it will not, among other things, sell, transfer, pledge, or permit others to use or otherwise dispose of such assets. The exclusive asset subscription agreement has a term of 10 years and can be extended at Zhixiang WFOE’s discretion.

Spousal Consent Letter

Pursuant to the spousal consent letter executed by the spouse of the Nominee Shareholders, the signing spouse unconditionally and irrevocably agreed that the equity interest in Shanghai Zhixiang held by and registered in the name of the Nominee Shareholders be disposed of in accordance with the exclusive option agreement, equity interest pledge agreement, proxy agreement, and other documents described above. The signing spouse agreed not to assert any rights over the equity interest in Shanghai Zhixiang held by the Nominee Shareholders. In addition, in the event that the signing spouse obtains any equity interest in Shanghai Zhixiang held by the Nominee Shareholders for any reason, she agrees to be bound by and sign any legal documents substantially similar to the contractual arrangements described above, as may be amended from time to time.

As a result of the VIE Contractual Arrangements, the Company has the power to direct the activities that most significantly impact Shanghai Zhixiang’s economic performance, bears the risks of and enjoys the rewards normally associated with the ownership of Shanghai Zhixiang. Therefore, management concluded that Shanghai Zhixiang is a consolidated VIE of the Company, of which the Company is the ultimate primary beneficiary. As such, the Group consolidated financial results of Shanghai Zhixiang in the consolidated financial statements.

Under the VIE Contractual Agreements, the Company has the power to direct activities of Shanghai Zhixiang through Zhixiang WFOE, and can have assets transferred freely out of Shanghai Zhixiang without restrictions. Therefore, the Company considers that there is no asset of Shanghai Zhixiang that can only be used to settle obligations of Shanghai Zhixiang, except for the registered capital and reserve funds of Shanghai Zhixiang with the aggregated amount of RMB1,566 as of December 31, 2020 and 2021. Since Shanghai Zhixiang are incorporated as limited liability companies under the PRC Law, creditors of Shanghai Zhixiang do not have recourse to the general credit of the Company.

The Company believes that the Zhixiang WFOE’s VIE Contractual Arrangements with Shanghai Zhixiang and the Nominee Shareholders are in compliance with PRC laws and regulations, as applicable, and are legally binding and enforceable. There are, however, uncertainties in the PRC legal system could limit the Company’s ability to enforce these contractual arrangements. Accordingly, the Company cannot be assured that the PRC government authorities will not ultimately take a view that is contrary to the Company’s belief and the opinion of its PRC legal counsel.

The Nominee Shareholders of Shanghai Zhixiang also own the majority of the voting shares of the Company. The enforceability, and therefore the benefits of the VIE Contractual Agreements between the Company and Shanghai Zhixiang depends on those individuals enforcing the contracts. There is a risk that the benefits of ownership between the Company and Shanghai Zhixiang may not be aligned in the future and they may fail to perform their contractual obligations. There would be a significant negative impact to the Company if these contracts were not enforced.

The Group’s operations depend on Shanghai Zhixiang to honor their VIE Contractual Agreements with the Group and the Company’s ability to control Shanghai Zhixiang also depends on the authorization by the Nominee Shareholders of Shanghai Zhixiang to exercise voting rights on all matters requiring shareholder approval in Shanghai Zhixiang. The Company believes that the agreements on authorization to exercise shareholder’s voting power are enforceable against each party thereto in accordance with their terms and applicable PRC laws or regulations currently in effect and the possibility that it will no longer be able to control and consolidate the VIEs as a result of the aforementioned risks and uncertainties is remote.

The following table sets forth the assets, liabilities, results of operations and changes in cash and cash equivalents of the consolidated VIEs, including Shanghai Zhixiang and the other VIE that had no significant operations, nor any material assets or liabilities, which were included in the Group’s consolidated financial statements with intercompany transactions eliminated:

Restricted net assets

17. Restricted net assets

Relevant PRC laws and regulations permit payments of dividends by the Group’s subsidiaries and consolidated VIE incorporated in the PRC only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Group’s subsidiaries and consolidated VIE in the PRC are required to annually appropriate 10% of their net after-tax income to the statutory general reserve fund prior to payment of any dividends, unless such reserve funds have reached 50% of their respective registered capital. As a result of these and other restrictions under PRC laws and regulations, the Group’s subsidiaries and consolidated VIE incorporated in the PRC are restricted in their ability to transfer a portion of their net assets to the Company either in the form of dividends, loans or advances. There are no significant differences between US GAAP and PRC accounting standards in connection with the reported net assets of the legally owned subsidiaries and the consolidated VIE in the PRC.

As of December 31, 2020 and 2021, the total restricted net assets of the Group’s subsidiaries and consolidated VIE incorporated in PRC and subjected to restriction amounted to approximately RMB659,579 and RMB1,611,371, respectively. Even though the Group currently does not require any such dividends, loans or advances from the PRC entities for working capital and other funding purposes, the Group may in the future require additional cash resources from them due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends or distributions to its shareholders. There is no other restriction on the use of proceeds generated by the Group’s subsidiaries and consolidated VIE to satisfy any obligations of the Group.

Certain risks and concentration

Dec. 31, 2021

Certain risks and concentration

Certain risks and concentration

4. Certain risks and concentration

(a) Credit and concentration risk

Financial instruments that potentially subject the Group to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, accounts receivable, short-term investment, amounts due from related parties and prepayments and other current assets. The maximum exposures of such assets to credit risk are their carrying amounts as of the balance sheets dates.

The Group expects that there is no significant credit risk associated with the cash and cash equivalents, restricted cash and short-term investments which are held by reputable financial institutions in the jurisdictions where the Company, its subsidiaries and VIEs are located. The Group believes that it is not exposed to unusual risks as these financial institutions have high credit quality.

Accounts receivables are typically unsecured and are primarily derived from revenue earned from mobile device charging provided for individuals and advertising services provided to customers. The following table summarized customers with greater than 10% of the account receivables:


	As of December 31,
	2020		2021
Customer A	*		17	%
Customer B	13	%	*

*	Less than 10%

ZMI (Hong Kong) International Company Limited (“ZMI”), a related party of the Group (Note 15), accounted for 60% and 40% of purchases for the years ended December 31, 2020 and 2021, respectively. In addition, supplier A, a third party of the Group, accounted for nil and 17% of purchases for the years ended December 31, 2020 and 2021, respectively.

(b) Foreign currency risk

For Group’s PRC entities, the operating transactions and its assets and liabilities are mainly denominated in RMB. RMB is not freely convertible into foreign currencies. The value of RMB is subject to changes influenced by central government policies, and international economic and political developments. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the PBOC. Remittances in currencies other than RMB by the Group in China must be processed through the PBOC or other China foreign exchange regulatory bodies which require certain supporting documentation in order to affect the remittance.

The Group is exposed to foreign currency exchange rate risk, which mainly affects the monetary assets denominated in the currencies other than the functional currencies of the respective entities. As of December 31, 2020 and 2021, such affected monetary assets primarily included cash and cash equivalents and restricted cash denominated in US$. Since July 21, 2005, the RMB has been permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. While the international reaction to the RMB appreciation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency policy, which could result in a further and more significant appreciation of the RMB against other currencies.

(d) Impact of COVID-19

Since 2020, in response to the outbreak of the novel strain of the coronavirus, COVID-19 (the "COVID-19 pandemic"), as well as its new variants, Chinese government has implemented, and continues to implement, a variety of restricted measures to reduce the spread of COVID-19. These measures have had adverse effect on the Group’s consumer behaviors, ability to expand points of interest coverage, workforce and operations. These COVID-19 outbreaks were generally followed by a significant drop in offline foot traffic as people were more likely to stay at home and the Group’s location partners were required to temporarily shut down due to measures implemented by the government, which negatively impacted the Group’s points of interest coverage and financial performance. Consequently, the Company’s revenues and average revenues per power bank decreased significantly in the first half of 2020 and in the second half of 2021.

In addition, the longer-term trajectory of COVID-19, both in terms of scope and its intensity, in China, together with its impact on the industry and the broader economy are still of significant uncertainties and remain difficult to predict, and any associated negative impact on the Group will depend on many factors beyond its control. The Group is closely monitoring its impact on the business, results of operations and financial conditions.

Income taxes

Income taxes

10. Income taxes

The Company is registered in the Cayman Island. The Group generates substantially all of its income/(loss) from its PRC operations.

Cayman

Under the current laws of Cayman, the Company is not subject to tax on income or capital gain. Additionally, upon payments of dividends to shareholders, no Cayman withholding tax will be imposed.

Hong Kong

Under the current Hong Kong Inland Revenue Ordinance, the subsidiary of the Group in Hong Kong is subject to 8.25% profit tax on the first HKD2 million taxable income and 16.5% profit tax on the remaining taxable income generated from operations in Hong Kong. Additionally, payments of dividends by the subsidiary incorporated in Hong Kong to the Company are not subject to any Hong Kong withholding tax.

PRC

In accordance with the Enterprise Income Tax Law (“EIT Law”), Foreign Investment Enterprises (“FIEs”) and domestic companies are subject to Enterprise Income Tax (“EIT”) at a uniform rate of 25%. The subsidiaries and consolidated VIE of the Group in the PRC are subject to a uniform income tax rate of 25% for all periods presented. Shanghai Zhixiang was entitled to be “Software Enterprise”. According to the new EIT Law and relevant regulations, from the year of 2019, Shanghai Zhixiang could enjoy a tax holiday of 2-year EIT exemption and subsequently 3-year 12.5% preferential tax rate.

The EIT 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 EIT 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, properties, 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 entities registered outside of the PRC should be considered as resident enterprises for the PRC tax purposes.

The EIT Law also imposes a withholding income tax of 10% on dividends distributed by a 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 issued 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 immediate holding company in Hong Kong is the beneficial owner of the FIE and owns directly at least 25% of the shares of the FIE). In accordance with accounting guidance, all undistributed earnings are presumed to be transferred to the parent company and withholding taxes should be accrued accordingly. All FIEs are subject to the withholding tax from January 1, 2008. The presumption may be overcome if the Group has sufficient evidence to demonstrate that the undistributed dividends from its PRC subsidiaries will be re-invested and the remittance of the dividends from its PRC subsidiaries will be postponed indefinitely.

As of December 31, 2020 and 2021, the aggregated amount of undistributed earnings and reserves of the Group entities located in the PRC that are available for distribution to the Company were RMB203,236 and RMB127,713, respectively. In accordance with the EIT Law, a withholding tax of 10%, or 5% subject to approval of Chinese tax authorities, will be imposed on the dividends when distributed to their immediate holding company outside of Mainland China. The Group plans to indefinitely reinvested undistributed earnings earned from its PRC subsidiaries in its operations in PRC. Therefore, no withholding income tax for undistributed earnings of its subsidiaries were provided as of December 31, 2020 and 2021.

The components of income before tax are as follows:

Deferred tax liabilities, net,	(16,230)	(33,891)	(34,445)

Note (a) — Deferred tax liabilities were provided for the unbilled service fee charged to VIEs by WFOEs pursuant to the exclusive business cooperation agreement entered into between VIEs and WFOEs as discussed in Note 1(b).

As of December 31, 2021, the Group had net operating loss carry forwards of approximately RMB384,305 which mainly arose from the subsidiaries and consolidated VIEs established in the PRC. The loss carries forwards from PRC entities will expire during the calendar year from 2025 to 2031. The net operating loss of the Group will start to expire if not utilized. Other than the expiration, there are no other limitations or restrictions upon Group’s ability to use these operating losses carry forwards.

As of December 31, 2021, net operating loss carry forwards from PRC entities will expire as follows:


At December 31,		RMB
2022		—
2023		—
2024		—
2025		579
2026		383,726

Movement of valuation allowance


	Year Ended
	December 31,
	2019	2020	2021
	RMB	RMB	RMB
Balance at the beginning of the year	464	474	621
Additions	10	147	46,809
Balance at the end of the year	474	621	47,430

As of December 31, 2020 and 2021, valuation allowances of RMB621 and RMB47,430 were provided because it was more likely than not that certain entities within the Group will not be able to utilize certain tax losses carry forwards and other deferred tax assets generated. If events occur in the future that allow these entities to realize more of its deferred tax assets than the presently recorded amount, an adjustment to the valuation allowances will increase income when those events occur.

Uncertain tax positions

The Group evaluates the level of authority for each uncertain tax position (including the potential application of interest and penalties) based on the technical merits, and measures the unrecognized benefits associated with the tax positions. As of December 31, 2020 and 2021, the Group did not have unrecognized uncertain tax positions.

(a)

It represents entry fees and prepaid commissions to location partners. As discussed in Note 2(r), entry fees paid to location partners are amortized on straight line basis over the contractual period with location partners during which the Group’s equipment is placed in location partners’ venues. In addition, since 2021, when entering into the location partner agreements, the Group agreed to prepay commissions to certain loction partners. The amount of the prepayment is based on the pre-agreed forecast of commissions to the location partners during the contractual period. The prepayment is used to offset the actual commissions to be paid to the local partners on monthly basis based on the pre-agreed monthly forecast of commissions. The location partners are obligated to refund to the Group any remaining prepayments if performance target is not met within a pre-agreed period.

The Group is closely monitoring the recoverability of these prepayments to location partners based on the actual performance of each of the location partners and no impairment charges were recorded as of December 31, 2020 and 2021.

(b)

It represents commission prepayment to third-party payment processing providers and is not readily withdrawable by the Group. The payment processing providers are engaged to facilitate the settlement with certain network partners and location partners for the commission payables. After the prepayment is made by the Group, network partners and location partners can draw down the commissions at their discretions. Upon draw down, the prepayment made to the payment processing providers and commission payables to network partners and location partners (Note 7) are derecognized accordingly.

- 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.

There was no income tax benefit recognized in the consolidated statements of comprehensive income/(loss) for share-based compensation expense and the Group did not capitalize any share-based compensation expense as part of the cost of any assets for the years ended December 31, 2019, 2020 and 2021. The Group makes an entity-wide accounting policy election to account for forfeitures when they occur.

(a)

Restricted shares

As disclosed in Note 10, on July 25, 2017, all 81,000,000 ordinary shares of the Company issued to Smart Share Holding were designated as restricted shares of the Company granted to the founders who are the owners of Smart Share Holding, in consideration for their continuous service to the Company as employees. Each founder was ascribed a particular number of the Company’s ordinary shares based on that founder’s ownership of Smart Share Holding.

The restricted shares shall be legally vested and released in equal 25% instalments over the four-year period from July 25, 2017 on each anniversary. Upon Qualified Public Offering, all the unvested restricted shares shall be vested immediately. Upon vesting, a founder is entitled to receive from Smart Share Holding any dividends received on their attributed portion of Company shares held by Smart Share Holding, and direct Smart Share Holding to dispose of their attributed portion of Company shares and receive the sale proceeds. Upon termination of employment with the Company, any unvested shares attributed to a founder can be repurchased by the Company for par value, and the founder would lose their economic rights associated with those shares. Accordingly, as the overall substance of the arrangement is a grant of share-based awards to founders, the Company has recorded share-based compensation expense on these awards.

The following table summarizes the Group’s restricted shares activities:


	Numbers of shares	Weighted-average grant date fair value
		US$
Unvested at December 31, 2018	60,750,000	0.0889
Vested	(20,250,000)	0.0889
Unvested at December 31, 2019	40,500,000	0.0889
Vested	(20,250,000)	0.0889
Unvested at December 31, 2020	20,250,000	0.0889
Vested	(20,250,000)	0.0889
Unvested at December 31, 2021	—	—

Share-based compensation expense for the restricted shares was measured using the estimated fair value of the Company’s ordinary shares of US$0.0889 at the grant date and is amortized to the consolidated statements of comprehensive income/(loss) on a straight-line basis over the vesting term.

For the years ended December 31, 2019, 2020 and 2021, the total fair value of restricted shares vested were RMB12,419, RMB 12,415 and RMB6,607, respectively.

Upon the completion of IPO, the 20,250,000 of unvested restricted shares owned by the founders of the Group were vested immediately according to the IPO vesting condition.

As of December 31, 2020 and 2021, there was RMB6,597 and nil of unrecognized shared-based compensation expense related to restricted shares, which is expected to be recognized over a period of 0.56 and nil years.

(b)

Smart Share CGY and Smart Share Brothers’ RSUs scheme (“RSUs scheme”)

As disclosed in Note 11, Smart Share CGY and Smart Share Brothers are solely owned by the founder of the Company and are the consolidated VIEs of the Company. Both Smart Share CGY and Smart Share Brothers were established to facilitate the adoption of an RSUs scheme on behalf of the Company. The RSUs scheme is administered by the board of directors of the Company and RSUs were granted to the Company’s employees and external consultants. All the ordinary shares of Smart Share CGY and Smart Share Brothers are authorised and issued to the founder to facilitate the adoption of the RSUs scheme.

The number of authorised and issued shares of Smart Share CGY and Smart Share Brothers were 44,841,250 and 2,000,000, respectively, which mirrored the number of the Company’s ordinary shares issued to Smart Share CGY and Smart Share Brothers, respectively. The founder holds the shares of Smart Share CGY and Smart Share Brothers on behalf of the Company and beneficiaries of the RSUs scheme. Other than holding the Company’s ordinary shares, Smart Share CGY and Smart Share Brothers do not have any other assets. The ordinary shares issued to Smart Share CGY and Smart Share Brothers are presented as treasury shares in the Company’s consolidated balance sheets.

Upon vesting, the Company’s employees and external consultants are entitled to the ordinary shares of Smart Share CGY or Smart Share Brothers, and the Company directs the founder to deliver such shares. Holders of vested shares of Smart Share CGY or Smart Share Brothers are entitled to the economics of the vested shares, including dividends and sale proceeds of these shares. Any proceeds received by Smart Share CGY or Smart Share Brothers on Company shares that have not been allocated to employees and external consultants are required to be returned to the Company. The RSUs granted by Smart Share CGY vest in the four-year period from the grant date, with 25% of the RSUs to be vested upon each anniversary. The RSUs granted by Smart Share Brothers are fully vested on the grant date. If an employee or external consultant terminates service to the Group, unvested shares of Smart Share CGY and Smart Share Brothers can be repurchased for nominal amounts. The Group has the right to repurchase vested shares of Smart Share CGY and Smart Share Brothers at a price based on recent transaction prices involving the Company’s stock. The ordinary shares of the Company held by Smart Share CGY and Smart Share Brothers are unchanged as a result of these transactions.

In January 2021, the Company's board of directors approved the modification of Smart Share CGY and Smart Share Brothers' RSUs scheme to allow the grantees to directly hold the ordinary shares or RSUs of the Company, under which each vested RSU of Smart Share CGY and Smart Share Brothers' RSUs scheme was exchanged for one ordinary share of the Company with an equivalent economic value, and each outstanding unvested RSU under the Smart Share CGY's RSUs scheme was exchanged for one RSU of the Company with an equivalent economic value. The modification did not change the vesting conditions and the remaining vesting period. There was no incremental share-based compensation cost recorded in connection with this modification.

The following table summarizes the Group’s RSUs activities:


	RSUs	Weighted Average
	Outstanding	Grant Date Fair Value
		US$
Unvested at December 31, 2018	9,824,454	0.1582

Forfeited	(861,193)	0.6266
Unvested at December 31, 2021	12,414,203	0.6037

The fair value of each granted RSUs is estimated based on the fair value of the underlying ordinary share of the Company on the date of grant, less any nominal amounts paid for such shares. The fair value of the RSUs granted by Smart Share Brothers was recognized as share-based compensation expense immediately on the grant date. The fair value of the RSUs granted by Smart Share CGY was amortized to the consolidated statements of comprehensive income/(loss) as share-based compensation expense on a straight-line basis over the vesting term.

The Company recognized share-based compensation expenses of RMB9,246, RMB17,340 and RMB20,130 related to RSUs in the consolidated statements of comprehensive income/(loss) for the years ended December 31, 2019, 2020 and 2021, respectively.

For the year ended December 31, 2021, as agreed with the employees in connection with the vesting of their RSUs, the employees transferred 2,306,690 vested RSUs to the Company, of which the aggregated fair value was RMB21,848 on the dates of transfer. The fair value of the transferred shares was determined by the market prices on the dates of transfer and was equivalent to the individual income taxes that the employees were liable to for the vesting of RSUs and the Company would settle with the local tax authority on behalf of the employees.

(c)Share Options

In January 2021, the shareholders and board of directors approved the 2021 Share Incentive Plan to attract and retain qualified personnel, provide incentives to employees, directors and consultants, and promote the success of the Group’s business. The 2021 Share Incentive Plan permits the awards of options, restricted share units, restricted shares or other types of award approved by a committee that administers the plan. The 2021 Share Incentive Plan assumed all awards that the Company had granted previously. The terms and conditions of the survived awards remain unchanged and continue to be effective and binding under the 2021 Share Incentive Plan.

In August 2021, the Board approved the Company to grant share options and restricted shares to purchase up to 5,055,208 Class A ordinary shares under the 2021 Share Incentive Plan. Accordingly, as of December 31, 2021, the Company granted 5,009,222 share options.

Share options granted under the 2021 Incentive Plan have a contractual term of ten years from the stated grant date and are generally subject to a four-year vesting schedule. Depending on the nature and the purpose of the grant, share-based awards generally vest 25% upon the first anniversary of the vesting commencement date, and 25%, 25% and 25% in following years thereafter.

The following table summarizes the Group’s option activities:


		Weighted	Weighted

The Group uses binomial option-pricing model determine fair value of the share-based awards. The estimated fair value of each option granted is estimated on the date of grant using the binomial option-pricing model with the following assumptions:


	Year ended December 31, 2021
Exercise price (US$)	0.01
Fair value of the ordinary share on the date of option grant (US$)	1.445
Expected volatility	62.97	%
Risk-free interest rate (per annum)	1.25	%
Expected dividend yield	0	%
Exercise multiple	2.2
Contractual term (in years)	10
Expected forfeiture rate (post-vesting)	5.24	%

Risk-free interest rate is estimated based on the yield curve of US Sovereign Bond as of the option valuation date. The expected volatility at the grant date and each option valuation date is estimated based on annualized standard deviation of daily stock price return of comparable companies with a time horizon close to the expected expiry of the term of the options. The Group has never declared or paid any cash dividends on its capital stock, and the Group does not anticipate any dividend payments in the foreseeable future. The exercise multiple is estimated as the ratio of fair value of underlying shares over the exercise price as at the time the option is exercised, based on a consideration of empirical studies on the actual exercise behavior of employees. Contractual term is the contract life of the options.

Share-based compensation expense is recorded on a straight-line basis over the requisite service period, which is generally four years from the date of grant. The Company recognized share-based compensation expenses of nil, nil and RMB3,936 for share options granted in the consolidated statements of comprehensive income/(loss) for the years ended December 31, 2019, 2020 and 2021, respectively.

As of December 31, 2020 and 2021, there was nil and RMB40,601 of unrecognized compensation expense related to unvested share options, which is expected to be recognized over a weighted average period of nil and 3.64 years, respectively.

If the Company’s assets or funds which are legally available on the date that any redemption payment is due are insufficient to pay in full all redemption payments to be paid, those assets or funds which are legally available shall be used to the extent permitted by applicable law to pay all redemption payments due on such date in the sequence of Series D-1 Preferred Share, Series C Preferred Share, Series B Preferred Share, Series A-1 Preferred Share, Series A Preferred Share and Series Seed Preferred Share, in a pro-rata manner in accordance with the relative full amounts owed thereon.

Voting rights

Each Preferred Share shall be entitled to the number of votes equal to the number of ordinary shares into which such Preferred Shares could be converted.

Conversion

Each holder of Preferred Shares shall be entitled to convert any or all of Preferred Shares, at any time, into such number of ordinary shares at an initial conversion ratio of 1:1 subject to customary anti-dilution adjustments.

The Preferred Shares shall automatically be converted into ordinary shares upon the closing of a Qualified Public Offering based on the then-effective conversion price. Qualified Public Offering means a firmly underwritten public offering of the ordinary shares on the Main Board of Hong Kong Stock Exchange, New York Stock Exchange, or NASDAQ Global Market, with an offering price (exclusive of underwriting commissions and expenses) that reflects the gross proceeds to the Company of at least US$100,000,000 and an implied pre-offering market capitalization of the Company of at least US$1,000,000,000, or in a similar public offering of the ordinary Shares of the Company which results in the ordinary shares trading publicly on another internationally recognized major securities exchange.

In April 2021, all classes of Preferred Shares of the Company were converted to Class A ordinary shares immediately prior to the completion of the IPO (Note 3).

Accounting and measurement for preferred shares

The Company classifies the Preferred Shares in mezzanine equity of the consolidated balance sheets because they are redeemable at the holders’ option any time upon the occurrence of certain events outside of the Company’s control. The Preferred Shares are recorded initially at fair value, net of issuance costs.

For each reporting period, the Company accretes the carrying amount of the Preferred Shares to the redemption value, which is the higher of (1) the result of using effective interest rate method to accrete the Preferred Shares to the redemption prices on the Optional Redemption Date, or (2) the fair market value of the Preferred Shares on the reporting date. The accretion is recorded against retained earnings, or in the absence of retained earnings, by charges against additional paid-in-capital, or in the absence of additional paid-in-capital, by charges to accumulated deficit until the Preferred Shares were converted. For the years ended December 31, 2019, 2020 and 2021, the accretion of the Preferred Shares was RMB406,828, RMB3,206,324 and RMB4,729,719, respectively.

The Company has determined that host contract of the Preferred Shares is more akin to an equity host, given the Preferred Shares holders have participating right in the Company like that of the ordinary shareholders, along with other equity-like features in the terms of the Preferred Shares, including the conversion and dividend rights. The Company has assessed each embedded feature in the Preferred Shares, and determined that the conversion and dividend feature to be clearly and closely related to the equity host, and none of these embedded features needs to be bifurcated from the equity host. The Company also assessed the liquidation feature and determined that the debt-like feature does not meet the net settlement and would not result in bifurcation.

The Company has determined that there were no beneficial conversion features identified for any of the Preferred Shares because the effective conversion price was greater than the fair value of the ordinary shares. To the extent a conversion price adjustment occurs, as described above, the Company will re-evaluate whether or not a beneficial conversion feature should be recognized.

The Company’s Preferred Shares activities for the years ended December 31, 2019, 2020 and 2021 are summarized below:

Accounting for warrant

The Company classified the warrant as financial liabilities under ASC 480 as the warrants conditionally obligated the Company to ultimately transfer assets. For the warrant issued in connection with the Series A-1 Preferred Shares, the proceeds were allocated first to the warrant based on its fair value and the residual was allocated to the Series A-1 Preferred Shares. For the warrant issued in connection with the loan, the warrant was recorded at its fair value when the loan was obtained with a corresponding reduction to the carrying amount of the loan as the debt issuance cost and was amortized on a straight-line basis over the loan period. The warrants were subsequently measured at fair value with changes in fair value recorded in the consolidated statements of comprehensive income/(loss).

The Company recognized a loss of RMB865 and RMB7,442 from the change in fair value of the warrant liabilities for the years ended December 31, 2019 and 2020, respectively.

The roll forward of major Level 3 investments are as following:

11. Ordinary shares

Upon inception on May 17, 2017, the Company issued 83,000,000 ordinary shares to Smart Share Holdings Limited (“Smart Share Holding”), a company jointly controlled by the founders of the Company, for nominal consideration. On June 1, 2017, Smart Share Holding transferred 2,000,000 ordinary shares to Smart Share Brothers for nominal consideration. On July 25, 2017, Smart Share Holding designated all 81,000,000 remaining ordinary shares of the Company it held as the founders’ restricted shares of the Company in exchange for the service of the founders as the Company’s employees.

From 2017 to 2019, the Company issued an aggregate of 44,841,250 ordinary shares to Smart Share CGY for nominal consideration. Smart Share CGY and Smart Share Brothers, the consolidated VIEs of the Company, were established to facilitate the adoption of the Company’s RSUs scheme. The Company’s ordinary shares issued to Smart Share CGY and Smart Share Brothers are presented as treasury shares in the consolidated balance sheets. See Note 13(b) for details.

On October 15, 2019, as approved by the Company’s board of directors and shareholders, the Company repurchased 7,026,030 and 275,000 ordinary shares from Smart Share Holding and Smart Share CGY, respectively, at the purchase price of US$0.8218 per share with an aggregate consideration of US$6 million (RMB42,070). This consideration was passed by Smart Share Holding and Smart Share CGY to the founders and employees who are considered as the holders of the economics associated with the ordinary shares repurchased. The shares were cancelled by the Company after the repurchase. Since the economics of the ordinary shares repurchased from Smart Share Holding and Smart Share CGY were ultimately held by the founders and employees of the Company as a result of the vesting of the restricted shares and RSUs, the excess of the repurchase price over the fair value of the Company’s ordinary shares on the date of the transaction of RMB17,421 in the aggregate was recorded as share based compensation expense within general and administrative expenses.

In January 2021, the Company's board of directors resolved the surrender of 34,703,970 ordinary shares of Smart Share Holdings and issued the corresponding 27,397,000 ordinary shares to Super June Limited and 7,306,970 ordinary shares to Victor Family Limited, respectively, for no consideration. Super June Limited and Victor Family Limited are entities owned by two founders of the Group respectively. After the transaction, each founder holds the same percentage of the equity interest of the Group directly as the ones used to be held indirectly through Smart Share Holding.

In January 2021, the Company's shareholders and board of directors approved a share incentive plan (the "2021 Share Incentive Plan") for its employees, directors and external consultants. In connection with the adoption of the 2021 Share Incentive Plan, the Company's board of directors have resolved the surrender of 44,566,250 ordinary shares of Smart Share CGY and 2,000,000 ordinary shares of Smart Share Brothers for no consideration.

Pursuant to a resolution made by the Company's board of directors and shareholders on March 12, 2021, the Company adopted a dual-class share structure. A total of 73,973,970 then issued and outstanding ordinary shares were re-designated and re-classed into Class B ordinary shares on a one-for-one basis immediately prior to the completion of the IPO. The remaining issued and outstanding ordinary shares and all the Series Seed, Series A, Series A-1, Series B-1, Series B-2, Series C-1, Series C-2, Series D-1 and Series D-2 Convertible Redeemable Preferred Shares were converted to Class A ordinary shares, in each case on a one-for-one basis immediately prior to the completion of the IPO. Each Class A ordinary share is entitled to one vote and each Class B ordinary share is entitled to 10 votes. Each Class B ordinary share is convertible into one Class A ordinary share at any time at the option of the holder thereof. Except for the voting and conversion rights, holders of Class A ordinary shares and Class B ordinary shares have the same rights.

In August 2021, the Company issued 28,000,000 Class A ordinary shares for nominal consideration and deposited these shares in the Bank of New York Mellon. Such shares were issued by the Company for the purpose to issue to the Company’s employees upon the vesting of their RSUs or the exercise of their share options under the Company’s 2021 Share Incentive Plan. Such shares are presented as treasury shares in the consolidated balance sheets until the issuance to the Company’s employees.

As of December 31, 2020, 609,026,779 ordinary shares had been authorized. As of December 31, 2020, 120,540,220 ordinary shares, at par value of US$0.0001 each, were issued, and 73,973,970 ordinary shares were outstanding.

As of December 31, 2021, the Company had 609,026,779 ordinary shares authorized, 452,898,177 shares of Class A Ordinary Shares and 73,973,970 shares of Class B Ordinary Shares issued, and 443,533,171 shares of Class A Ordinary Shares and 73,973,970 shares of Class B Ordinary Shares were outstanding, respectively.
