Summary of Significant Accounting Policies | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) Basis of Presentation The accompanying consolidated financial statements of the Group have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). (b) Principles of Consolidation The consolidated financial statements include the financial statements of the Company and its subsidiaries. All intercompany transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation. (c) Use of Estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, related disclosures of contingent assets and liabilities at the balance sheet date, and the reported revenues and expenses during the reported period. Significant accounting estimates include, but not limited to, fair value of share-based compensation awards. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences may be material to the consolidated financial statements. (d) Commitment and Contingencies In the normal course of business, the Group is subject to loss contingencies, such as legal proceedings and claims arising out of its business, that cover a wide range of matters, including, among others, government investigations, shareholder lawsuits, and non-income tax matters. An accrual for a loss contingency is recognized when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. If a potential material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material, is disclosed. (e) Cash and Cash Equivalents Cash and cash equivalents consist of cash at bank and highly liquid investments placed with financial institutions, which have original maturities of three months or less and are readily convertible to known amounts of cash. The Group’s cash and cash equivalents are deposited in financial institutions at below locations: As of December 31, 2022 2023 US$ US$ Financial institutions in the mainland PRC —Denominated in Chinese Renminbi (“RMB”) 13,639,079 5,766,176 —Denominated in U.S. Dollar (“USD”) 10,013,699 33,287,688 Total cash and cash equivalents balances held at mainland PRC financial institutions 23,652,778 39,053,864 Financial institutions in Hong Kong Special Administrative Region (“HK S.A.R.”) —Denominated in USD 105,481,683 112,226,871 —Denominated in Hong Kong Dollar (“HKD”) 158,251 54,584 —Denominated in RMB 8,896 10,122 Total cash and cash equivalents balances held at the HK S.A.R. financial institutions 105,648,830 112,291,577 Financial institutions in UAE —Denominated in United Arab Emirates Dirham (“AED”) 6,858,066 5,636,696 —Denominated in USD 237,038,304 128,818,035 —Denominated in RMB — 3,572,231 Total cash and cash equivalents balances held at the UAE financial institutions 243,896,370 138,026,962 Financial institutions in United States —Denominated in USD 465,475 20,110,736 Total cash and cash equivalents balances held at the United States financial institutions 465,475 20,110,736 Financial institutions in Singapore —Denominated in USD 13,359,499 1,616,771 —Denominated in Singapore Dollar (“SGD”) 233,885 93,284 —Denominated in RMB — 690,269 Total cash balances held at the Singapore financial institutions 13,593,384 2,400,324 Financial institutions in United Kingdom —Denominated in USD 20,000,000 — Total cash equivalents balances held at the United Kingdom financial institutions 20,000,000 — Total cash and cash equivalents balances held at financial institutions 407,256,837 311,883,463 Cash and cash equivalents, restricted cash and term deposits, with financial institutions in the mainland PRC, Hong Kong S.A.R., United States and Singapore are insured by the government authorities up to RMB 500,000 , HKD 500,000 , US$ 250,000 and SGD 75,000 per bank, respectively. Cash and cash equivalents, restricted cash and term deposits are insured by the government authorities with amounts up to US$ 2,640,889 and US$ 2,726,340 as of December 31, 2022 and 2023, respectively. The Company has not experienced any losses in uninsured bank deposits and does not believe that it is exposed to any significant risks on cash and term deposits held in bank accounts. To limit exposure to credit risk, the Company primarily places bank deposits with large financial institutions in the mainland PRC, Hong Kong S.A.R., United Arab Emirates, United States and Singapore with acceptable credit rating. (f) Restricted cash Cash that is restricted to withdrawal or for use is reported separately on the consolidated balance sheets. The group’s restricted cash mainly represents restricted deposit used as security against a lawsuit. (g) Term deposits Term deposits represent deposits placed with banks with original maturities of more than three months but less than one year. The Group’s term deposits as of December 31, 2022 and 2023 were denominated in USD and were deposited at financial institutions in United Kingdom and HK S.A.R.. (h) Investments Debt securities Debt securities consist of held-to-maturity debt securities that the Company has positive intent and ability to hold to maturity. The Company accounts for the held-to-maturity debt security at amortized cost less allowance for credit losses. The net carrying amount of held-to-maturity debt securities was nil and US$ 50,363,727 as of December 31, 2022 and 2023, respectively, which was included in the long-term investments in the consolidated balance sheets. Credit loss of held-to-maturity debt securities was nil as of December 31, 2022 and 2023. As of December 31, 2023, the held-to-maturity debt securities were with contractual maturities of over one year and less than two years . Equity securities All equity securities with readily determinable fair values, other than those accounted for under equity method of accounting or those that result in consolidation of the investee, are measured at fair value with changes in the fair value recognized through net income. Equity securities without readily determinable fair values which do not qualify for net asset value per share (or its equivalent) practical expedient and over which the Group does not have the ability to exercise significant influence through the investments in common stock, are accounted for under the measurement alternative. The carrying values of equity investments without readily determinable fair values are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. All gains and losses on these investments, realized and unrealized, are recognized through net income. The Group makes assessment of whether an investment is impaired at each reporting date, and recognizes an impairment loss equal to the difference between the carrying value and fair value through net income. The carrying amount of equity securities without readily determinable fair value were US$ 4,551,666 and US$ 3,869,895 as of December 31, 2022 and 2023, respectively. Impairment loss of US$ 705,428 and US$ 2,509,480 were recognized for the years ended December 31, 2022 and 2023, respectively. (i) Property and Equipment, net Property and equipment are stated at cost less depreciation and any impairment. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, as follows: Category Estimated Useful Life Electronic equipment 3 years Vehicle 4 years Office furniture 3 - 5 years Leasehold improvements Shorter of the lease term or the estimated useful life of the assets Ordinary maintenance and repairs are charged to expenses as incurred, while replacements and betterments are capitalized. When items are retired or otherwise disposed of, income is charged or credited for the difference between net book value of the item disposed and proceeds realized thereon. Property and equipment are reviewed for impairment when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Recoverability of a long-lived asset or asset group to be held and used is measured by a comparison of the carrying amount of an asset or asset group to the estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the carrying value of an asset or asset group exceeds its estimated undiscounted future cash flows, an impairment loss is recognized by the amount that the carrying value exceeds the estimated fair value of the asset or asset group. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third party independent appraisals, as considered necessary. Assets to be disposed are reported at the lower of carrying amount or fair value less costs to sell, and are no longer depreciated. No impairment of long-lived assets was recognized for the years presented. (j) Intangible asset, net Intangible asset represents domain names purchased and trademarks registered, which are stated at cost on the date of acquisition or registration less accumulated amortization. Intangible asset is amortized using the straight-line method over the estimated useful lives of the asset, as follows: Category Estimated Useful Life Domain names 3 - 5 years Trademarks 10 years (k) Value Added Taxes The Company’s PRC subsidiaries and UAE subsidiaries are subject to value added tax (“VAT”). Revenue from providing services is generally subject to VAT at the rate of 6 % for PRC subsidiaries and 5 % for UAE subsidiaries, respectively. The Group paid to local tax authorities after netting input VAT on purchases. The excess of output VAT over input VAT is reflected in accrued expenses and other current liabilities, and the excess of input VAT over output VAT is reflected in prepayments and other current assets in the consolidated balance sheets. (l) Fair Value Measurements Fair value represents 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. As such, fair value is a market‑based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures (“ASC 820”) defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Accounting guidance establishes a three‑level fair value hierarchy and 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 are: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Include other inputs that are directly or indirectly observable in the marketplace. Level 3 — Unobservable inputs which are supported by little or no market activity. Accounting guidance also describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The cost approach is based on the amount that would currently be required to replace an asset. Financial assets and liabilities of the Group primarily consist cash and cash equivalents, term deposits, short-term investments, long-term investments, accounts payable, accrued expenses and other current liabilities. The Group measures short-term investments at fair value on a recurring basis. Short-term investments issued by financial institutions, which are valued based on price per unit quoted by financial institutions. They are categorized in Level 1 and Level 2 of the fair value hierarchy. Long-term investments are equity securities without readily determinable fair value and held-to-maturity debt investments. Equity securities without readily determinable fair value are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. As of December 31, 2022 and 2023, the carrying values of financial instruments other than equity securities without readily determinable faire value approximated to their fair values. The following table sets forth the Company’s assets that are measured at fair value on a recurring basis and are categorized under the fair value hierarchy: Fair value measurement as of December 31, 2022 using Level 1 Level 2 Level 3 Total fair value as of December 31, 2022 US$ US$ US$ US$ Assets Short-term investments 2,963,052 22,825,252 — 25,788,304 Fair value measurement as of December 31, 2023 using Level 1 Level 2 Level 3 Total fair value as of December 31, 2023 US$ US$ US$ US$ Assets Short-term investments — 10,282,329 — 10,282,329 (m) Revenue Recognition The Group has adopted ASC 606, Revenue from Contracts with Customers , since its establishment and recognizes revenue when control of the promised services are transferred to the customers, in an amount that reflects the consideration that the Group expects to receive in exchange for those services. The revenues of the Group were primarily derived from its online social networking and gaming platform, which provides group chatting and games services through mobile applications. Group chatting service The Group provides group chatting service to individual users with free access to the basic functions on the platform. It also provides enhanced experience by sales of virtual items and provision of upgrade service on the platform. The Group has the sole discretion in designing the specifications and establishing pricing of virtual items and upgrade service. Individual user purchases virtual items and upgrade service using the Group’s virtual currencies which are in turn acquired through third party payment platforms. The Group recognizes revenue relating to virtual items at the point-in-time when they are consumed. Upgrade service primarily consists of VIP rights or premium membership in chat rooms over a specified limited service period or the service period the users are registered on the platform. Revenues from the upgrade service with limited service period are recognized ratably over the period the service is made available to the users. Revenues from the upgrade service without any time limits are recognized ratably over the estimated service period of the relevant user groups. Games service The Group provides games service to individual users through its mobile game applications. Individual users consume virtual currencies to play a game, purchase virtual items which can be used to enjoy one time privileges in the game, and upgrade service. Each game is completed within several minutes. The Group charges individual users virtual currencies to play a game, which currently accounts for a small portion of games service revenue. The Group has determined that each of these games represents a distinct performance obligation. The related revenue is recognized over the period of the gameplay which takes several minutes. The Group recognizes revenue relating to virtual items upon consumption. Upgrade service primarily consists of premium rights over the period the users are registered on the platform. Revenues from the upgrade service are recognized ratably over the estimated service period of the relevant user groups. The estimated service period of upgrade services in both the group chatting service and games service is determined based on the expected service period derived from historical users’ behavioral pattern. This estimate is re-assessed on a quarterly basis. Adjustments arising from the changes of estimated period of the users are applied prospectively as such changes are resulted from new information indicating a change in the users’ behavior. Deferred revenue Virtual currencies are non-refundable and does not have expiration date. Proceeds received from users’ purchase of virtual currencies are recorded as deferred revenue. Deferred revenue (a contract liability) is recognized when the Group has an obligation to transfer services to a customer for which the Group has received consideration related to the Group’s group chatting and games services from the customer through mobile applications. The balance of deferred revenue as of January 1, 2021, 2022, and 2023 was US$ 13,359,827 , US$ 24,971,203 and US$ 35,957,485 respectively, of which US$ 13,359,827 , US$ 24,971,203 and US$ 35,147,512 were recognized as revenue for the years ended December 31, 2021, 2022, and 2023, respectively. US$ 43,610,021 and US$ 2,948,550 of the balance of deferred revenue as of December 31, 2023 is expected to be recognized as revenues in 2024 and 2025 , respectively. (n) Cost of Revenues Cost of revenues consists primarily of (i) commission fees paid to third party payment platforms, and (ii) staff cost and expenses related to the operations of the mobile platforms. (o) Selling and Marketing Expenses Selling and marketing expenses mainly consist of (i) advertising costs and market promotion expenses, and (ii) staff cost, rental and depreciation related to selling and marketing functions. Advertising costs, which consist primarily of online advertisements, are expensed as incurred. The advertising costs were US$ 26,699,326 , US$ 37,972,955 and US$ 33,769,334 for the years ended December 31, 2021, 2022 and 2023, respectively. (p) General and Administrative Expenses General and administrative expenses mainly consist of (i) staff cost, rental and depreciation related to general and administrative personnel, (ii) professional service fees; and (iii) other corporate expenses. (q) Technology and Product Development Expenses Technology and product development expenses consist primarily of (i) staff cost, and (ii) related expenses for the employees involved in designing and developing new features for the mobile platforms and self-developed mobile games. All technology and product development expenditures are expensed as incurred. (r) Government Grants Government grants generally consist of financial subsidies received from local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. The eligibility to receive such benefits and amount of financial subsidy to be granted are determined at the discretion of the relevant government authorities. Government grants are recognized when there are reasonable assurances that the Group will comply with the conditions attach to them and the grants will be received. Government grants for the purpose of giving immediate financial support to the Group with no future related costs or obligation are recognized in the Group’s consolidated statements of comprehensive income when the grants become receivable. US$ 1,419,837 , US$ 322,273 and US$ 337,355 were recognized in government grants for the years ended December 31, 2021, 2022, and 2023, respectively. There were no significant commitment or contingencies for the government subsidies received for the years ended December 31, 2021, 2022 and 2023. (s) Share‑based Compensation The Group periodically grants share-based awards, mainly including share options to eligible employees and management. The Group recognizes compensation cost for an equity classified award on a tranche-by-tranche basis. The Group’s equity awards contain service condition. The Group recognized the compensation cost over the requisite service period. To the extent the required vesting conditions are not met resulting in the forfeiture of the share-based awards, previously recognized compensation expense relating to those awards is reversed. (t) Employee Benefits The Company’s subsidiaries in PRC participate in a government mandated, defined contribution plan, pursuant to which certain retirement, medical, housing and other welfare benefits are provided to employees. PRC labor laws require the entities incorporated in China to pay to the local labor bureau a monthly contribution calculated at a stated contribution rate on the compensation of qualified employees. The Group has no further commitments beyond its monthly contribution. Employee social benefits US$ 3,782,043 , US$ 6,484,213 and US$ 7,051,506 were recognized for the years ended December 31, 2021, 2022 and 2023, respectively. (u) Income Taxes Current income taxes are provided on the basis of income before income taxes for financial reporting purposes, and 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 tax assets and liabilities are recognized for the tax effects of temporary differences and are determined by applying enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates or tax laws is recognized in the consolidated statements of comprehensive income in the period the change in tax rates or tax laws is enacted. A valuation allowance is provided to reduce the amount of deferred income tax assets if based on the weight of available evidence, it is more‑likely‑than‑not that some portion, or all, of the deferred income tax assets will not be realized. The Group applies a “more likely than not” recognition threshold in the evaluation of uncertain tax positions. The Group recognizes the benefit of a tax position in its consolidated financial statements if the tax position is “more likely than not” to prevail based on the facts and technical merits of the position. Tax positions that meet the “more likely than not” recognition threshold are measured at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. Unrecognized tax benefits may be affected by changes in interpretation of laws, rulings of tax authorities, tax audits, and expiry of statutory limitations. In addition, changes in facts, circumstances and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Accordingly, unrecognized tax benefits are periodically reviewed and re‑assessed. Adjustments, if required, are recorded in the Group’s consolidated financial statements in the period in which the change that necessities the adjustments occurs. The ultimate outcome for a particular tax position may not be determined with certainty prior to the conclusion of a tax audit and, in certain circumstances, a tax appeal or litigation process. The Group records interest and penalties related to unrecognized tax benefits (if any) in interest expenses and general and administrative expenses, respectively. As of December 31, 2022 and 2023, the Group did no t have any unrecognized uncertain tax positions. (v) Leases The Group leases premise for offices under non-cancellable operating leases. Prior to January 1, 2021, payments made under the operating lease were charged to the consolidated statements of comprehensive income on a straight-line basis over the terms of underlying lease. Leases with escalated rent provisions were recognized on a straight-line basis commencing with the beginning of the lease terms. There were no capital improvement funding, lease concessions or contingent rent in the lease agreements. The Group has no legal or contractual asset retirement obligations at the end of the lease terms. The Group adopted Accounting Standards Codification Topic 842, Leases (“ASC 842”) as of January 1, 2021, using a modified retrospective method for leases that exist at, or are entered into after, January 1, 2021. The adoption of ASC 842 requires the recognition of operating lease right-of-use assets and operating lease liabilities on the balance sheet. The Group elected the package of practical expedients that not to reassess: (1) whether any expired or existing contracts are or contain leases, (2) lease classification for any expired or existing leases, and (3) initial direct costs for any expired or existing leases. The Group also elected the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The Group used its estimated incremental borrowing rate based on information available at the date of adoption in calculating the present value of its existing lease payments. The Group determines if an arrangement is a lease at inception. The operating lease liabilities are recognized upon lease commencement for operating leases based on the present value of lease payments over the lease terms. The operating lease right-of-use assets are initially measured at cost, which comprises the initial amount of the operating lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. As the rate implicit in the lease cannot be readily determined, the incremental borrowing rate at the lease commencement date is used in determining the imputed interest and present value of lease payments. The incremental borrowing rate was determined using a portfolio approach based on the rate of interest that the Group would have to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Group recognizes the single lease cost on a straight-line basis over the remaining lease terms for operating leases. The Group has elected not to recognize operating lease right-of-use assets or operating lease liabilities for leases with an initial term of 12 months or less. Expenses for these leases are recognized on a straight-line basis over the lease term. (w) Foreign Currency The Company’s reporting currency is United States Dollars (“US$”). The functional currency of the Company and its subsidiaries incorporated in UAE, HK S.A.R., Singapore and British Virgin Islands is US$. The functional currency of the Company’s PRC subsidiaries is RMB. Transactions denominated in currencies other than the functional currency are remeasured into the functional currency at the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currency are remeasured into the functional currency using the applicable exchange rate at the balance sheet date. The resulted exchange differences are recorded in general and administrative expenses in the consolidated statements of comprehensive income. The financial statements of the Company’s PRC subsidiaries are translated from RMB into US$. Assets and liabilities are translated into US$ using the applicable exchange rates at the balance sheet date. Equity accounts other than earnings or deficits generated in the current period are translated into US$ using the appropriate historical rates. Revenues, expenses, gains and losses are translated into US$ using the average exchange rates for the relevant period. The resulted foreign currency translation adjustments are recorded as a component of other comprehensive income or loss in the consolidated statements of comprehensive income, and the accumulated foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss) as a component of consolidated statements of changes in equity. (x) Concentration and risk The Group’s cost of revenues mainly included commission fees paid to third party payment platforms, among which two third party payment platforms individually represent greater than 10% of the Group’s cost of revenues excluding payroll and welfare and depreciation for the years ended December 31, 2021, 2022 and 2023 are as follows: For the Year Ended December 31, 2021 2022 2023 A 52 % 41 % 32 % B 25 % 20 % 24 % (y) Earnings per Share Basic earnings per share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the year using the two-class method. Under the two-class method, net income is allocated between ordinary shares and other participating securities based on their participating rights. Shares issuable for little to no consideration upon the satisfaction of certain conditions are considered as outstanding shares and included in the computation of basic earnings per share as of the date that all necessary conditions have been satisfied. Net losses are not allocated to other participating securities if based on their contractual terms they are not obligated to share the losses. Diluted earnings per share is calculated by dividing net income attributable to ordinary shareholders, as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the year. Ordinary equivalent shares consist of ordinary shares issuable upon the exercise of share options using the treasury stock method. Ordinary equivalent shares are not included in the denominator of the diluted earnings per share calculation when inclusion of such share would be anti-dilutive. (z) Segment Reporting The Group uses the management approach in determining its operating segments. The Group’s chief operating decision maker has been identified as the Chief Executive Officer, who reviews consolidated results when making decisions about allocating resources and assessing performance of the Group. For the purpose of internal reporting and management’s operation review, the Group’s Chief Executive Officer does not segregate the Group’s business by product or service lines. Management has determined that the Group has one operating segment, which is the social networking and entertainment platform. (aa) Geographic Information Long-lived assets consist of property and equipment, operating lease right-of-use assets, intangible asset and other assets. The geographic information for long-lived assets of the Group’s for the years ended December 31, 2022 and 2023 are as follows: As of December 31, 2022 2023 US$ US$ Domestic component UAE 995,692 397,377 Foreign components Mainland PRC 18,630,833 16,714,825 HK S.A.R. — 62,872 Cayman Islands 1,180,000 940,000 Total long-lived assets 20,806,525 18,115,074 (bb) Statutory Reserve In accordance with the PRC Company Laws, the PRC subsidiaries must make appropriations from their after-tax profits as determined under the generally accepted accounting principles in the PRC (“PRC GAAP”) to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10 % of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50 % of the registered capital of the PRC companies. Appropriation to the discretionary surplus fund is made at the discretion of the PRC companies. The statutory surplus fund and discretionary surplus fund are restricted for use. They may only be applied to offset losses or increase the registered capital of the respective companies. These reserves are not allowed to be transferred to the Company by way of cash dividends, loans or advances, nor can they be distributed except for liquidation. As of December 31, 2022 and 2023, the statutory reserve of the Company’s PRC subsidiaries was US$ 1,699,677 and US$ 2,206,638 , respectively. UAE Company Laws requires 5 % of Yalla Dubai’s annual net profits to be set aside as a statutory reserve. This allocation may be suspended by a shareholders’ decision once the reserve has reached an amount equal to 50 % of |
