SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompany consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Principles of Consolidation The consolidated financial statements of the Group include the financial statements of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation. Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s consolidated financial statements include, but are not limited to, the useful lives and impairment of long‑lived assets, tax valuation allowance, share‑based compensation expenses and the fair value of warrant liabilities. Management bases the estimates on historical experience and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could materially differ from those estimates. Foreign currency translation The functional currency of the Company, Adagene (Hong Kong) Limited, Adagene Incorporated and Adagene PTE. Ltd. is the United States dollar (“US$”). The functional currency of the Company’s PRC subsidiary is Renminbi (“RMB”). The functional currency of the Company’s Australia subsidiary is Australian dollar (“AU$”). The functional currency of the Company’s Switzerland subsidiary is Swiss Franc (“CHF”). The determination of the respective functional currency is based on the criteria stated in Accounting Standard Codification (“ASC”) 830, Foreign Currency Matters . The Company uses US$ as its reporting currency. The financial statements of the Company’s PRC, Australia and Switzerland subsidiaries are translated from the functional currency to the reporting currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates quoted by the People’s Bank of China (the “PBOC”) prevailing on the transaction dates. Monetary assets and liabilities denominated in foreign currencies are re‑measured at the exchange rates prevailing at the balance sheet date. Non‑monetary items that are measured in terms of historical costs in foreign currency are re‑measured using the exchange rates at the dates of the initial transactions. Exchange gains and losses are included in the consolidated statements of comprehensive loss. 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 year. Translation adjustments are reported as accumulated comprehensive loss and are shown as a separate component of other comprehensive loss in the consolidated statements of comprehensive loss. Cash and cash equivalents Cash and cash equivalents primarily consist of cash and demand deposits which are highly liquid. The Group considers highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of three months or less to be cash equivalents. All cash and cash equivalents are unrestricted as to withdrawal and use. Short‑term investments Short‑term investments are deposits at bank with maturities of greater than three months, but less than twelve months. Short‑term investments are stated at cost, which approximates fair value. Interest earned is included in interest income. Accounts receivable and allowance for doubtful accounts Account receivable is recorded when the Group has an unconditional right to consideration. A right to consideration is unconditional if only the passage of time is required before payment of that consideration is due. Accounts receivable are carried at net realizable value. An allowance for doubtful accounts is recorded in the period when collection of the amount is no longer probable. In evaluating the collectability of receivable balances, the Group considers specific evidence including the aging of the receivable, the customer’s payment history, its current credit‑worthiness and other factors. Accounts receivable are written off when management determines a balance is uncollectable after all collection efforts have ceased. Fair value measurements The Group applies 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. ASC 820 requires disclosures to be provided for fair value measurements. ASC 820 establishes a three‑tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2—Includes other inputs that are directly or indirectly observable in the marketplace. Level 3—Unobservable inputs which are supported by little or no market activity. ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach; and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. The carrying amounts of cash and cash equivalent, short‑term investments, accounts receivable, amounts due to related parties and other current assets, accounts payable, amounts due to related parties, accrued liabilities and other current liabilities and short‑term borrowings approximate their fair values because of their generally short maturities. The carrying amount of long‑term borrowings approximate their fair values since they bear interest rates which approximate market interest rates. As more fully described in Note 8, the Group issued warrants to two Series C-1 preferred shareholders to purchase its preferred shares. The warrants have expired on April 1, 2019. The Group measured its warrant liabilities at fair value on a recurring basis. As the Group’s warrants are not traded in an active market with readily observable prices, the Group uses significant unobservable inputs to measure the fair value of warrant liabilities. These instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. The following table presents a reconciliation of all financial instruments measured at fair value on a recurring basis using Level 3 unobservable inputs: Warrant liabilities US$ Initial recognition during the year ended December 31, 2018 1,741,720 Fair value change (534,305) Balance as of December 31, 2018 1,207,415 Fair value change (1,207,415) Balance as of December 31, 2019 — The Group did not transfer any assets or liabilities in or out of Level 3 during the years ended December 31, 2018, 2019 and 2020. The Group had no financial assets and liabilities measured and recorded at fair value on a nonrecurring basis as of December 31, 2019 and 2020. Property, equipment and software Property and equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight‑line method over the estimated useful lives of the assets as follows: Category Estimated Useful Life Machinery and laboratory equipment 5 years Vehicles 4 years Furniture and tools 3 - 5 years Electronic equipment 3 years Computer software 3 - 5 years Leasehold improvements Lesser of lease terms or estimated useful lives of the assets Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful lives of property, equipment and software are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation and amortization from the asset and accumulated depreciation and amortization accounts with any resulting gain or loss reflected in the consolidated statements of comprehensive loss. Impairment of long‑lived assets The Group evaluates the recoverability of its long‑lived assets, including fixed assets and intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Group measures impairment by comparing the carrying amount of the assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available. The adjusted carrying amount of the assets is the new cost basis and is depreciated over the assets’ remaining useful lives. Long‑lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. No impairment loss was recorded for the years ended December 31, 2019 and 2020. Segment reporting In accordance with ASC 280, Segment Reporting , the Group’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer. The Group’s CODM reviews the consolidated results of operations when making decisions about allocating resources and assessing performance of the Group. The Group operates and manages it business as a single segment. No geographical segments are presented as substantially all of the Group’s long‑lived assets are located in the PRC. Revenue recognition At contract inception of collaboration and out‑licensing arrangements, the Group analyzes its arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Group first determines which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are reflective of a vendor‑customer relationship and therefore within the scope of ASC 606. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied consistently. Under the criteria of Accounting Standard Codification (“ASC”) 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”), the Group recognizes revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. The Group adopted ASC 606 for all periods presented. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Group only applies the five‑step model to contracts when it is probable that the entity will collect substantially all the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. The Group reviews the contract to determine which performance obligations are distinct and represent a promise to provide distinct goods or services or a series of distinct goods or services as defined by the standard. The Group recognizes as revenue the amount of the transaction price that is allocated to each performance obligation as and when that performance obligation is satisfied. Licenses of Intellectual Property: Upfront non‑refundable payments for licensing the Group’s intellectual property are evaluated to determine if the license is distinct from the other performance obligations identified in the arrangement. For licenses determined to be distinct, the Group recognizes revenues from non‑refundable, up‑front fees allocated to the license at a point in time, when the transfer of control of the license to the licensee occurs and the licensee is able to use and benefit from the license. Milestone Payments: At the inception of each arrangement that includes development, commercialization, and regulatory milestone payments, the Group evaluates whether the milestones are considered probable of being reached and to the extent that a significant reversal of cumulative revenue would not occur in future periods, estimates the amount to be included in the transaction price using the most likely amount method. The transaction price is then allocated to each performance obligation on a relative stand‑alone selling price basis, for which the Group recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Group re‑evaluates the probability of achieving such development milestones and any related constraint, and if necessary, adjust the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch‑up basis, which would affect revenues and earnings in the period of adjustment. Royalties: For arrangements that include sales‑based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Group recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, no milestone payments or royalty payments were received. Substantially all of the Group’s revenue has been derived from its out‑licensing agreements with respect to licensed products such as DNA sequences, cell lines, etc., and such revenues are recognized when the customer obtains control of the licensed product, which occurs at a point in time, upon delivery to the customer. Contract assets and contract liabilities When a customer pays consideration before the Group transfers products or services, the Group records its obligation as a contract liability; When the Group satisfies its performance obligations by providing products or services to a customer before the customer pays consideration and before payment is due, the Group recognizes its rights to consideration as a contract asset. Research and development expenses Elements of research and development expenses primarily include (1) payroll and other related costs of personnel engaged in research and development activities, (2) costs related to pre‑clinical testing of the Group’s technologies under development and clinical trials such as payments to contract research organizations (“CRO”) and contract manufacturing organizations (“CMO”), investigators and clinical trial sites that conduct the clinical studies; (3) costs to develop the product candidates, including raw materials and supplies, product testing, depreciation and amortization, and facility related expenses, (4) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to the Group’s research and development services and have no alternative future uses. As of December 31, 2020, the Group has several ongoing clinical studies in various clinical trial stages. The contracts with CRO and CMO are generally cancellable, with notice, at the Group’s option. The Group did not record any accrued expenses related to cancellation of CRO or CMO contracts as of December 31, 2020 as the Group did not have any plan to cancel the existing CRO or CMO contracts. Government subsidies Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the governments. The Group’s PRC based subsidiary received government subsidies from certain local government. The Group’s government subsidies consist of specific subsidies and other subsidies. Specific subsidies are subsidies that the local government has set certain conditions for the subsidies. Other subsidies are the subsidies that the local government has not set any conditions and are not tied to future trends or performance of the Group, receipt of such subsidy income is not contingent upon any further actions or performance of the Group and the amounts do not have to be refunded under any circumstances. The Group recorded specific subsidies as other non‑current liabilities when received and recognized as other income when the conditions are met. Other subsidies are recognized as other income upon receipt as further performance by the Group is not required. Leases Leases are classified at the inception date as either a capital lease or an operating lease. The Group assesses a lease to be 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 on a straight‑line basis over their respective lease terms. The Group leases certain office space under non‑cancelable operating lease agreements. Certain lease agreements contain rent holidays. Rent holidays are considered in determining the straight‑line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the leased property for purpose of recognizing lease expense on straight‑line basis over the term of the lease. Comprehensive loss Comprehensive loss is defined as the changes in equity of the Group during a period from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Accumulated other comprehensive loss of the Group includes foreign currency translation adjustments related to the Group and its subsidiaries whose functional currency is not US$. Income taxes The Group follows the liability method of accounting for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rate is recognized in tax expense in the period that includes the enactment date of the change in tax rate. The Group evaluates its uncertain tax positions using the provisions of ASC 740, which prescribes a recognition threshold that a tax position is required to meet before being recognized in the consolidated financial statements. The Group recognizes in the consolidated financial statements the benefit of a tax position which is “more likely than not” to be sustained under examination based solely on the technical merits of the position assuming a review by tax authorities having all relevant information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is the Group’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense. Borrowings Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the consolidated statements of comprehensive loss over the period of the borrowings using the effective interest method. Share‑based compensation The Company grants restricted shares and stock options to eligible employees and nonemployees and accounts for share-based compensation in accordance with ASC 718, Compensation—Stock Compensation. Share-based compensation awards are measured at the grant date fair value of the awards and recognized as expenses a) immediately at the grant date if no vesting conditions are required; or b) for share-based awards granted with only service conditions, using the straight-line method over the vesting period; or c) for share-based awards granted with service conditions and performance conditions, using the graded vesting method over the vesting period if and when the company concludes that it is probable that the performance conditions will be achieved. A change in any of the terms or conditions of share-based awards is accounted for as a modification of the awards. The Group calculates incremental compensation expense of a modification as the excess of the fair value of the modified awards over the fair value of the original awards immediately before its terms are modified at the modification date. For vested awards, the Group recognizes incremental compensation cost in the period when the modification occurs. For awards not being fully vested, the Group recognizes the sum of the incremental compensation expense and the remaining unrecognized compensation expense for the original awards over the remaining requisite service period after modification. Net loss per share In accordance with ASC 260, Earnings Per Share , basic net loss per share is computed by dividing net loss attributable to ordinary shareholders by the weighted average number of unrestricted ordinary shares outstanding during the year using the two‑class method. Under the two‑class method, net loss is allocated between ordinary shares and other participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company’s convertible redeemable preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. Diluted net loss per share is calculated by dividing net loss 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 period. Ordinary equivalent shares include ordinary shares issuable upon the conversion of the convertible redeemable preferred shares using the if‑converted method, and ordinary shares issuable upon the exercise of share options, using the treasury stock method. Ordinary share equivalents are excluded from the computation of diluted earnings per share if their effects are anti‑dilutive. For the periods presented herein, the computation of basic net loss per share using the two‑class method is not applicable as the Group is in a net loss position and the participating securities do not have contractual rights and obligations to share in the losses of the Group. Employee defined contribution plan As stipulated by the regulations of the PRC, full‑time employees of the Group are entitled to staff welfare benefits including medical care, welfare subsidies, unemployment insurance and pension benefits through a PRC government‑mandated multi‑employer defined contribution plan. The Group is required to accrue for these benefits based on certain percentages of the qualified employees’ salaries. The Group is required to make contributions to the plans out of the amounts accrued. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed. The Group has no further payment obligations once the contributions have been paid. The Group recorded employee benefit expenses of US$1,145,165 and US$622,377 for the years ended December 31, 2019 and 2020, respectively. Concentration of risks Concentration of credit risk As of December 31, 2019 and 2020, the aggregate amount of cash and cash equivalents and short‑term investments of US$801,923 and US$3,424,456 respectively, were held at major financial institutions located in the mainland of China, and US$99,730,865 and US$71,726,542, respectively, were deposited with major financial institutions located outside the mainland of China. Management believes that these financial institutions are of high credit quality and continually monitors the credit worthiness of these financial institutions. Accounts receivable are typically unsecured and denominated in US$ and are derived from revenues earned from customers. The Group manages credit risk of accounts receivable through ongoing monitoring of the outstanding balances. Concentration of suppliers A significant portion of the Group’s research and development services were purchased from its one supplier, who collectively accounted for 23.13% and 21.51% of the Group’s total research and development services purchases for the years ended December 31, 2019 and 2020, respectively. Business and economic risk The Group believes that changes in any of the following areas could have a material adverse effect on the Group’s future consolidated financial position, results of operations or cash flows: changes in the overall demand for services; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in certain strategic relationships; regulatory considerations and risks associated with the Group’s ability to attract employees necessary to support its growth. The Group’s operations could also be adversely affected by significant political, regulatory, economic and social uncertainties in the PRC. Foreign currency exchange rate risk A significant portion of the Group’s businesses are transacted in RMB, which is not a freely convertible currency. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts. From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For U.S. dollar against RMB, there was appreciation and depreciation of approximately 1.3% and 6.5% in the years ended December 31, 2019 and 2020, respectively. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future. The functional currency and the reporting currency of the Company are the US$. However, large portion of the expenses of the Group are denominated in RMB. Any significant fluctuation of the valuation of RMB may materially affect the Group’s cash flows, expenses, losses and financial position, and the value of any dividends payable on the American Depositary Shares in US$. Recently issued accounting pronouncements The Group is an emerging growth company (“EGC”) as defined by the Jumpstart Our Business Startups Act (“JOBS Act”). The JOBS Act provides that an EGC can take advantage of extended transition periods for complying with new or revised accounting standards. This allows an EGC to delay adoption of certain accounting standards until those standards would otherwise apply to private companies. The Group elected to take advantage of the extended transition periods. However, this election will not apply should the Group cease to be classified as an EGC. In February 2016, the FASB issued ASU No. 2016‑02 (“ASU 2016‑02”), Leases (Topic 842), which modifies lease accounting for lessees to increase transparency and comparability by recording lease assets and liabilities for operating leases and disclosing key information about leasing arrangements. In July 2018, the FASB issued ASU No. 2018‑10 (“ASU 2018‑10”), Codification Improvements to Topic 842, Leases, which clarifies certain aspects of the guidance issued in ASU 2016‑02; and ASU No. 2018‑11 (“ASU 2018‑11”), Leases (Topic 842): Targeted Improvements, which provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative‑effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases). Further, the FASB issued ASU No. 2020-05 (“ASU 2020-05”), Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which extends the adoption date for certain entities. For the Group, the updated guidance is effective for fiscal years beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Group does not plan to early adopt the new lease standards and the Group expects that applying the ASU 2016‑02 would materially increase the assets and liabilities due to the recognition of right‑of‑use assets and lease liabilities on its consolidated balance sheets, with an immaterial impact on its consolidated statements of comprehensive loss and consolidated statements of cash flows. In June 2016, the FASB issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016‑13”). ASU 2016‑13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU requires enhanced disclosures to help |

In November 2014, the Company issued 5,473,957 Series A‑1 convertible redeemable preferred shares (“Series A‑1 Preferred Shares”) to certain investors upon conversion of the Company’s Series Pre‑A convertible notes at a conversion price of US$1 per share. Concurrently, the Company issued 2,370,414 Series A‑2 convertible redeemable preferred shares (“Series A‑2 Preferred Shares”) to certain investors at US$1.27 per share for a total consideration of US$3,000,000. Series A‑1 Preferred Shares and Series A‑2 Preferred Shares are collectively referred to as the Series A Preferred Shares. From January through June 2016, the Company issued 7,494,537 Series B convertible redeemable preferred shares (“Series B Preferred Shares”) to certain investors at US$3.74 per share for a total consideration of US$27,999,995. From February through May 2018, the Company issued 5,597,354 Series C‑1 convertible redeemable preferred shares (“Series C‑1 Preferred Shares”) to certain investors at US$8.93 per share for a total consideration of US$50,000,033. Concurrently, in February 2018, the Company also issued warrants to two Series C‑1 investors at nil consideration (“Series C‑1 Warrants”). The Series C‑1 Warrants allowed the holders to purchase Series C‑2 Preferred Shares (defined below) at the exercise price of US$10.21 per share for a total consideration of up to US$7,500,000. Series C‑1 Warrants were exercisable, in whole or in part, at any time from the warrant issuance date to the earlier of i) April 1, 2019, ii) a deemed liquidation event or iii) the closing of the Qualified IPO. Series C‑1 Warrants expired on April 1, 2019. From June through November 2019, the Company issued 1,861,121 Series C‑2 convertible redeemable preferred shares (“Series C‑2 Preferred Shares”) to certain investors at US$10.21 per share for a total consideration of US$18,999,999. In December 2019, the Company issued 4,452,441 Series C‑3 convertible redeemable preferred shares (“Series C‑3 Preferred Shares”) to a certain investor at US$11.23 per share for a total consideration of US$50,000,000. Series C‑1 Preferred Shares, Series C‑2 Preferred Shares and Series C‑3 Preferred Shares are collectively referred to as the Series C Preferred Shares. The key features of the Series A Preferred Shares, Series B Preferred Shares and Series C Preferred Shares (collectively the “Preferred Shares”) are as follows: Dividends Each holder of the Preferred Shares will be entitled to receive non‑cumulative dividends when declared by the Board of Directors prior and in preference to ordinary shareholders. The dividend should be paid at the rate of 6% of the original issue price per share per annum on each Preferred Shares in the sequence of Series C Preferred Shares and Preferred Shares other than the Series C Preferred Shares. After the preferential dividends relating to the Preferred Shares have been paid in full or declared and set apart in any fiscal year of the Company, any additional dividends out of funds or assets legally available therefore may be declared in that fiscal year for the Shares and, if such additional dividends are declared, the preferred shareholders shall be entitled to participate on an as converted‑basis pro‑rata in any dividends or distributions paid to the ordinary shareholders. Voting Each Preferred Share has voting rights equivalent to the number of ordinary shares to which it is convertible at the record date. The Preferred Shares shall vote separately as a class with respect to certain specified matters. Otherwise, the preferred shareholders and ordinary shareholders shall vote together as a single class. Liquidation preference In the event of any liquidation, dissolution or winding up of the Company, or the cessation of the business of the Company or of a substantial portion of the business of the Company, whether voluntary or involuntary, or any deemed liquidation event (unless waived by the preferred shareholders), the preferred shareholders shall be entitled to receive a per share amount equal to 100% of the original issue price of the respective series of the Preferred Shares, in the sequence of Series C Preferred Shares, Series B Preferred Shares and Series A Preferred Shares. After such liquidation amounts have been paid in full, the preferred shareholders are entitled to receive a simple interest accruing on each Preferred Share at 6% of its original issue price per annum from the date of issuance of such Preferred Share to the date of distribution of such amount, in the sequence of Series C Preferred Shares, Series B Preferred Shares and Series A Preferred Shares. After such interest amounts have been paid in full, any remaining funds or assets of the Company legally available for distribution to shareholders shall be distributed on a pro rata basis among the preferred shareholders, on an as‑converted basis, together with the ordinary shareholders. Conversion Each Preferred Share may be converted at any time into ordinary shares at the option of the preferred shareholders based on the then‑effective conversion price. The initial conversion ratio is 1:1, subject to adjustment in the event of share splits, share combinations, ordinary share dividends or distributions, other dividends, reorganizations, mergers, consolidations, reclassifications, exchanges, substitutions, or dilutive issuance. All Preferred Shares are converted automatically into ordinary shares at the then effective applicable conversion price upon the earlier of a Qualified Public Offering (public offering of the Company’s shares with an offering price (exclusive of underwriting commissions and expenses) that reflects a market capitalization (immediately prior to the public offering) of not less than US$650,000,000 and with an aggregate proceeds of no less than US$75 million)or a date specified by written consent or agreement of the holders of at least 80% of the voting power of the then outstanding Preferred Shares. Redemption The Preferred Shares are redeemable upon request by the holders of the majority outstanding Preferred Shares if the Company fails to consummate a Qualified Public Offering or complete a deemed liquidation event on or before March 31, 2025 at the redemption price equal to the original issue price plus any declared but unpaid dividends. Accounting for Preferred Shares The Preferred Shares are classified as mezzanine equity in the consolidated balance sheets because they are contingently redeemable upon the occurrence of an event outside of the Company’s control (e.g. the Company not achieving a Qualified Public Offering or a deemed liquidation event before March 31, 2025 (“Target QIPO Date”)). The Preferred Shares were determined to be mezzanine equity with no embedded feature to be bifurcated and no beneficial conversion features to be recognized. The Preferred Shares are initially recorded at their respective issuance date fair value, net of issuance cost and fair value allocated to the detachable warrants. The Company did not incur material issuance cost for any Preferred Shares issued. The Company concluded that the Preferred Shares are not currently redeemable, but are probable to become redeemable. The Company accreted changes in the redemption value over the period from the date of issuance to the earliest redemption date using the interest method. No accretion charge was recorded as the redemption value is fixed to original issue price for the years presented, except for Series C‑1 Preferred Shares issued with detachable warrants. Modification of Preferred Shares The Company made several amendments to the Preferred Shares, mainly including: 1) added redemption rights for Series A Preferred Shares upon the issuance of the Series B Preferred Shares; 2) extended the Target QIPO Date upon the issuance of the Series C‑1 Preferred Shares and the Series C‑3 Preferred Shares. These amendments are accounted for as modifications rather than extinguishments as the fair values of these Preferred Shares immediately after the amendments were not significantly different from their respective fair values immediately before the amendment. When Preferred Shares are modified and such modification results in value transfer between preferred shareholders and ordinary shareholders, the value transferred is treated as a deemed dividend to or deemed contribution from the preferred shareholders. On February 2, 2018, the Target QIPO Date was extended from January 19, 2023 to February 2, 2025 (7th anniversary of Series C‑1 closing) upon issuance of Series C‑1 Preferred Shares. On the date of the modifications, the Company assessed the total fair value of preferred shares immediately before and after the change of the terms with the assistance from an independent third‑party appraiser. The combined change in fair value of Preferred Shares immediately before and after the modification was US$1,186,187. The increase in fair value of the ordinary shares of is US$1,186,187, in substance, a transfer of wealth mostly from the preferred shareholders to the ordinary shareholder, and therefore are recorded as deemed contribution from the Preferred Shareholders. The Company’s Preferred Shares activities for the periods presented are summarized below: Mezzanine equity Series A‑1 Series A‑2 Series B Series C‑1 Series C‑2 Series C‑3 Total US$ US$ US$ US$ US$ US$ US$ Balance as of December 31, 2017 5,473,957 3,000,000 27,999,995 — — — 36,473,952 Issuance of Series C‑1 Preferred Shares — — — 48,258,313 — — 48,258,313 Accretion of Series C‑1 Preferred Shares to redemption value — — — 222,846 — — 222,846 Balance as of December 31, 2018 5,473,957 3,000,000 27,999,995 48,481,159 — — 84,955,111 Issuance of Series C‑2 Preferred Shares — — — — 18,999,999 — 18,999,999 Issuance of Series C‑3 Preferred Shares — — — — — 50,000,000 50,000,000 Accretion of Series C‑1 Preferred Shares to redemption value — — — 246,184 — — 246,184 Balance as of December 31, 2019 5,473,957 3,000,000 27,999,995 48,727,343 18,999,999 50,000,000 154,201,294 Accretion of Series C‑1 Preferred Shares to redemption value — — — 248,113 — — 248,113 Balance as of December 31, 2020 5,473,957 3,000,000 27,999,995 48,975,456 18,999,999 50,000,000 154,449,407 The warrants are freestanding instruments and classified as liabilities in accordance with ASC 480. The warrants are initially recognized at fair value, with subsequent changes in fair value recorded currently in earnings. The Company recognized gains from the decrease in fair value of the warrants of US$534,305, US$1,207,415 and nil for the years ended December 31, 2018, 2019 and 2020, respectively. The Company has measured the warrant liabilities at fair values on a recurring basis using significant unobservable inputs (Level 3) for the years ended December 31, 2018. The Group used the Black‑Scholes option pricing model to estimate the fair value of warrant liabilities using the following assumptions: For the year ended December 31, 2018 Risk‑free interest rate 1.92%, 2.37% Exercise price US$10.2089 Maturity date 01/04/2019 Estimated volatility rate 63.78%, 71.00% The model requires the input of highly subjective assumptions including the risk‑free rate interest rate, maturity date, estimated volatility rate and fair value of underlying preferred shares. The risk‑free rate for periods within the contractual life is based on the US treasury strip bond with maturity similar to the maturity of the warrants as of valuation dates. For expected volatilities, the Company has made reference to the historical daily stock prices volatilities of ordinary shares of several comparable companies in the same industry as the Company. The estimated fair value of the preferred shares was determined with assistance from an independent third‑party valuation firm. The significant unobservable inputs used in the fair value measurement of the warrant liabilities include risk‑free interest rate, interval between valuation date and maturity date, estimated volatility rate and fair value of underlying preferred shares. Significant decreases in interval between valuation date and maturity date, estimated volatility rate and fair value of underlying preferred shares would result in a significantly lower fair value measurement. Significant increases in risk‑free interest rate would result in a significantly lower fair value measurement. |

SHARE-BASED COMPENSATION | |
SHARE-BASED COMPENSATION | 9. SHARE‑BASED COMPENSATION On November 7, 2015, the Company adopted a share incentive plan (“2015 Plan”). Under the 2015 Plan, the Company’s Board of Directors has approved that a maximum aggregate number of shares that may be issued pursuant to all awards granted shall be 4,336,126. In September 2017, the Company replaced 2015 Plan with the amended and restated share incentive plan (“2017 Plan”) and increased the maximum number of shares issuable to 6,336,126. In December 2019, the Company replaced 2017 Plan with the second amended and restated share incentive plan (“2019 Plan”) and further increased the maximum number of shares issuable to 11,391,131. The terms of the 2015 Plan, 2017 Plan and 2019 Plan are substantially the same other than the maximum aggregate number of shares the Company may issue under the respective plan. Share options containing only service conditions granted to each grantee under the share incentive plan will generally be exercisable upon the grantee renders service to the Company in accordance with a stipulated vesting schedule. Grantees are generally subject to a vesting schedule of no longer than five years, under which the grantee earns an entitlement to vest a certain percentage of his option grants at the end of each month or year of completed service. The share option awards shall expire no more than 10 years from their grant dates. Share options containing both service conditions and performance conditions granted to each grantee under the share incentive plan shall become eligible for vesting upon the occurrence of their applicable performance conditions (including but not limited to the occurrence of an initial public offering ("IPO"), the completion of business and operational goals, etc.). Upon being eligible for vesting, each such performance-based option shall vest in a series of four equal and continuous annual installments for each full year of services completed following the award date of such option. On August 15, 2020, pursuant to board resolution, 184,692 share options that granted to a senior management was modified and the vesting period of the 184,692 share options has been shortened from 5 years to 4 years. Since the fair value of the modified award is lower than the fair value of the original award immediately before the modification, there is no incremental compensation cost to be recognized. On November 9, 2020, the Company passed a board resolution to waive the vesting schedules and conditions of 2,375,000 share options granted to certain management members. Pursuant to this board resolution, these management members exercised all these share options at the original exercise price per share ranging from US$1.83 to US$2.26 and as a result, 2,375,000 ordinary shares were issued to them. These management members paid the exercise price by issuing recourse promissory notes in the total amount of US$5,197,650. However, the Company still has the repurchase right to buy back such shares at the original exercise price if the grantees do not meet the original vesting conditions. The Company assessed and considered that in accordance with guidance set out in ASC 718-10-55-31, given such arrangement allows the shares received on exercise be returned to the Company if the original vesting conditions are not satisfied, there has been no substantial change to the vesting conditions and the Company shall continue to account for the share awards in accordance with their original terms. As of December 31, 2020, there were 2,285,000 shares unvested according to the original vesting conditions. As of December 31, 2020, the Company has granted 2,178,808 share options containing both service conditions and performance conditions. All other share options granted contain only service conditions.

The aggregate fair value of the equity awards vested during the years ended December 31, 2018, 2019 and 2020 was US$165,609, US$366,113 and US$8,430,085, respectively. As of December 31, 2020, there was US$34,096,227 of total unrecognized employee share‑based compensation expense, may be adjusted for actual forfeitures occurring in the future. Total unrecognized compensation cost will be recognized over a weighted‑average period of 3.39 years. Fair value of share options The fair value of share options was determined using the binomial option valuation model, with the assistance from an independent third‑party appraiser. The binomial model requires the input of highly subjective assumptions, including the expected volatility, the exercise multiple, the risk‑free rate and the dividend yield. For expected volatility, the Group has made reference to historical volatility of several comparable companies in the same industry. The exercise multiple was estimated as the average ratio of the stock price to the exercise price of when employees would decide to voluntarily exercise their vested share options. The risk‑free rate for periods within the contractual life of the share options is based on the market yield of U.S. Treasury Bonds in effect at the time of grant. The dividend yield is based on the expected dividend policy over the contractual life of the share options. The estimated fair value of the ordinary shares, at the share option grant dates, was determined with the assistance from an independent third‑party appraiser. The assumptions used to estimate the fair value of the share options granted are as follows: For the year For the year ended ended December 31, December 31, 2019 2020 Risk‑free interest rate 1.78% - 2.73% 0.68% - 0.83% Dividend yield 0% 0% Expected volatility range 67.5% - 71.0% 72.3% - 73.4% Exercise multiple 2.2 - 2.8 2.2 - 2.8 Contractual life 10 years 10 years Total share‑based compensation expenses recognized for the years ended December 31, 2018, 2019 and 2020 were as follows: For the years ended December 31, 2018 2019 2020 US$ US$ US$ Research and development expenses 126,540 404,620 6,472,083 Administrative expenses — 207,091 3,657,458 Total share‑based compensation expenses 126,540 611,711 10,129,541 Up to the date of the issuance of these consolidated financial statements, some proceeds of the subscription capital arising from the exercise of vested share options by certain employees remained outstanding and such amount was presented as subscriptions receivable, a contra‑equity balance on the consolidated balance sheets as of December 31, 2019 and 2020, respectively. |

COLLABORATION ARRANGEMENTS | |
COLLABORATION ARRANGEMENTS | 10. COLLABORATION ARRANGEMENTS Guilin Sanjin Pharmaceutical Co., Ltd. License Agreement In December 2018, the Group entered into (i) a collaboration agreement (the “Sanjin Greater China Agreement”) that covers Greater China with Guilin Sanjin Pharmaceutical Co., Ltd. (“Sanjin”) and certain of its subsidiaries (collectively, “Sanjin Parties”) and (ii) a collaboration agreement (the “Sanjin ROW Agreement”, together with the Sanjin Greater China Agreement, the “2018 Sanjin Agreements”) that covers the regions other than Greater China with Sanjin. Pursuant to the Sanjin Greater China Agreement, the Group licensed the Chinese intellectual property directly related to a monospecific antibody molecule that binds to the PD‑L1 target (the “PD‑L1 Project”), including patent rights, patent application rights and technologies based on the core sequence of the molecule, to Sanjin Parties. Sanjin Parties will own all the Chinese intellectual property developed in the exercise of Sanjin Parties’ rights under the agreement, including but not limited to improvements (including combination products), clinical trials, regulatory filings, and commercialization rights relating thereto. The Group also granted Sanjin Parties a royalty‑free license to use our other existing intellectual property and improvements thereto which are related to the PD‑L1 Project for the purposes of exploiting its rights and performing its obligations under the agreement. Sanjin Parties will enjoy all the economic benefits deriving from the PD‑L1 Project in Greater China, including but not limited to patent transfer fee, licensing fee, sales revenue and sales commission, etc. Sanjin Parties will pay the Group (i) single‑digit percentage of net sales of the products that use the licensed antibody after such products enter the market and (ii) a low to mid‑low double‑digit percentage of the profits resulting from any transfer of the license to any third parties depending on the timing of the transfer relative to the development stage of the product. The Group also received RMB10,000,000 (equivalent to approximately US$1,511,168) upfront fee upon the effectiveness of the agreement from Sanjin Parties. Pursuant to the Sanjin ROW Agreement, the Group granted Sanjin a royalty‑free license to use all intellectual property relating to (i) the collaboration under the agreement that the Group controlled before the Group entered into the agreement or acquired independently of the agreement and (ii) improvements thereto for the purposes of exploiting its rights and performing its obligations under the agreement. Any intellectual property generated independently by a party under the agreement will be solely owned by that party who generated such intellectual property, and any intellectual property generated from cooperation between the Group and Sanjin’s affiliates in connection with the collaboration will be jointly owned. The Group retain the ownership of patent rights of key intellectual property pertaining to PD‑L1 outside of the Greater China. In addition, all the results obtained by Sanjin relating to the research and development of any new antibody developed under the agreement will be owned by Sanjin. The Group retain a majority of the economic benefits derived from the Sanjin ROW Agreement, including but not limited to any patent transfer fee, licensing fee and gains realized under such transfer. In case the Group intend to transfer to a third party our share of economic interests in any country outside of Greater China, the Group must notify Sanjin and Sanjin will receive a right of first refusal if it pays the Group a deposit equal to a low double‑digit percentage of the consideration that the Group expect to receive from such third party. If Sanjin waives the right of first refusal, the Group can proceed with the transfer, provided that the final transaction price with the third party is not lower than the amount of the offering price that was included in our notice to Sanjin. The Group agreed not to (i) independently develop any monospecific antibodies that bind to the PD‑L1 target or (ii) grant any rights associated with such antibodies to any third parties during the three‑year period from the effective date of the agreement. The exclusivity obligation does not prevent the Group from (i) developing or granting any licenses to third parties for intellectual property that covers bispecific antibodies, ADCs, diagnostic antibodies, nano‑particles and masked antibody against PD‑L1 target and (ii) continuing to provide antibody screening service that were commenced before the execution of the Sanjin Greater China Agreement and either party has the independent right to conduct combination therapy studies outside of the Greater China. Either non‑breaching party may terminate the 2018 Sanjin Agreements if the other party’s ability to comply with its respective obligations under the agreements is negatively affected by contingencies such as failure to maintain operation or changes in core project management and the other party fails to take effective remedial measures. Each agreement automatically terminates upon the termination of the other agreement. Upon the rescission or termination, Sanjin Parties will return to the Group all the intellectual property, documents and data provided by the Group under the 2018 Sanjin Agreements. In the event that the failure of the development of the product candidate solely arises from the Group’s research and development basis specified under this agreement, Sanjin has the right to claim back all the payment made to the Group. The Group considers the possibility of occurrence of such event is very remote. For the year ended December 31, 2018, the Group recognized revenue of RMB10,000,000 (equivalent to approximately US$1,511,168) for this agreement. Dragon Boat Biopharmaceutical (Shanghai) Limited License Agreement In May 2019, the Group entered into (i) a collaboration agreement that covers Greater China (the “Dragon Boat Greater China Agreement”) and (ii) a collaboration agreement that covers the regions other than Greater China (the “Dragon Boat ROW Agreement,” together with the Dragon Boat Greater China Agreement, the “2019 Dragon Boat Agreements”), with Dragon Boat Biopharmaceutical (Shanghai) Limited (“Dragon Boat”), a subsidiary of Sanjin. Pursuant to the Dragon Boat Greater China Agreement, the Group will license the Chinese intellectual property directly related to a certain monospecific antibody molecule that binds to a specified target (the “Specified Project”), including the patent rights, patent application rights and technologies based on the core sequence of the molecule, to Dragon Boat. Dragon Boat will own all the Chinese intellectual property developed in the exercise of Dragon Boat’s rights under the agreement, including but not limited to improvements (including combination products), clinical trials, regulatory filings, and commercialization rights relating thereto. The Group also granted Dragon Boat a royalty‑free license to use our other existing intellectual property and improvements thereto which are related to the Specified Project for the purposes of exploiting its rights and performing its obligations under the agreement. Dragon Boat will enjoy all the economic benefits deriving from the Specified Project in Greater China, including but not limited to patent transfer fee, licensing fee, sales revenue and sales commission, etc. and will pay the Group (i) certain high‑six figure dollar milestone payments upon the achievement of certain milestones (including milestones of launch of pre‑clinical safety evaluation animal test, obtaining Investigational New Drug (“IND”) approval in PRC and completion of clinical phase I test in PRC) and (ii) a single‑digit percentage of net sales of the products that use the licensed antibody after such products enter the market. Pursuant to the Dragon Boat ROW Agreement, the Group granted Dragon Boat a royalty‑free license to use all intellectual property relating to (i) the collaboration under the agreement that the Group controlled before the Group entered into the agreement or acquired independently of the agreement and (ii) improvements thereto for the purposes of exploiting its rights and performing its obligations under the agreement. Any intellectual property generated independently by a party under the agreement will be solely owned by that party who generated such intellectual property, and any intellectual property generated from cooperation between the Group and Dragon Boat in connection with the collaboration will be jointly owned. The Group retain the ownership of patent rights of key intellectual property pertaining to the specified target outside of the Greater China. In addition, all the results obtained by Dragon Boat relating to the research and development of any new antibody developed under the agreement will be owned by Dragon Boat. The Group retains a majority of the economic benefits derived from the Dragon Boat ROW Agreement, including but not limited to any patent transfer fee, licensing fee and gains realized under such transfer. In case the Group intend to transfer to a third party our share of economic interests in any country outside of Greater China, the Group must notify Dragon Boat and Dragon Boat will receive a right of first refusal if it pays the Group a deposit equal to a low double‑digit percentage of the consideration that the Group expects to receive from such third party. If Dragon Boat waives the right of first refusal, the Group can proceed with the transfer, provided that the final transaction price with the third party is not lower than the amount of the offering price that was included in our notice to Dragon Boat. Under the 2019 Dragon Boat Agreements, the Group agreed not to (i) independently develop any monospecific antibodies that bind to the specified target or (ii) grant any rights associated with such antibodies to any third parties during the three‑year period from the effective date of the agreements. The exclusivity obligation does not prevent the Group from (i) developing or granting any licenses to third parties for intellectual property that covers bispecific antibodies, ADCs, diagnostic antibodies, nano‑particles and masked antibody against the specific target and (ii) continuing to provide antibody screening service that were commenced before the execution of the Dragon Boat Greater China Agreement and either party has the independent right to conduct combination therapy studies outside of the Greater China. Either nonbreaching party may terminate the 2019 Dragon Boat Agreements if the other party’s ability to comply with its obligations under the agreements is negatively affected by contingencies such as failure to maintain operation or changes in core project management and the other party fails to take effective remedial measures. Each agreement automatically terminates upon the termination of the other agreement. Upon the rescission or termination, Dragon Boat will return to the Group all the intellectual property, documents and data provided by the Group under the 2019 Dragon Boat Agreements. In the event that the failure of the development of the product candidate solely arises from the Group’s research and development basis specified under this agreement, Dragon Boat has the right to claim back all the payment made to the Group. For the year ended December 31, 2019, no revenue was recognized for this agreement since the licensed product has not been transferred to Dragon Boat. As of December 31, 2020, upfront fee of RMB4,000,000 (equivalent to approximately US$573,378) that was received by the Group was recorded as contract liabilities in the consolidated balance sheets, as the performance obligation had not been satisfied by the Group. Signal Pharmaceuticals LLC Agreements In January 2019, the Group entered into an agreement with Signal Pharmaceuticals LLC, a subsidiary of Celgene Corporation, for a purchase order of delivery of certain sequences with total consideration of US$480,000. For the year ended December 31, 2019, the Group recognized revenue of US$480,000 upon delivery of such sequences. In October 2018 and May 2019, the Group entered into agreements with Signal Pharmaceuticals LLC, for purchase orders of for a purchase order of delivery of certain sequences with total consideration of US$237,500 and US$72,000, respectively. For the year ended December 31, 2020, the Group recognized revenue of US$309,500 upon delivery of such sequences. ADC Therapeutics SA License and Collaboration Agreements In April 2019, the Group entered into a material transfer and collaboration agreement (the “ADCT Collaboration Agreement”) and a license agreement (the “ADCT License Agreement”) with ADC Therapeutics SA (“ADC Therapeutics”). These two agreements are combined as a single contract as the agreements were negotiated as a package with a single commercial objective. ADCT Collaboration Agreement Pursuant to the ADCT Collaboration Agreement, the Group agreed to generate masked antibodies with respect to up to two exclusive targets selected by ADC Therapeutics. Upon our delivery of certain initial results, ADC Therapeutics has the option to license the Group’s technology with respect to one or both targets as further detailed below. ADC Therapeutics has not yet exercised such options as of December 31, 2020. Under the ADCT Collaboration Agreement, the Group is eligible to receive up to a low‑seven‑figure dollar amount in consideration for the Group’s exclusivity obligations, upon achievement of certain development milestones (including milestones of delivery of certain amino acid sequences and successful outcome of the first in‑vivo study) and upon ADC Therapeutics’ election to proceed with development for the two elected targets. Apart from performance obligation to deliver the amino acid sequences of the corresponding masking peptides, the Group is not required to perform any additional research and development services. ADC Therapeutics has the right to terminate the ADCT Collaboration Agreement at any time and for any reason in its entirety or on a target‑by‑target basis upon thirty days’ prior written notice to the Group. Either party may terminate the ADCT Collaboration Agreement, in its entirety or on a target‑by‑target basis, upon the other party’s uncured material breach of the agreement or the other party’s insolvency‑related events. The Group also granted ADC Therapeutics an exclusive target reservation right for one year from the commencement of the agreement and an option to renewal for another year with a consideration of low‑six‑figure dollar amount. ADCT License Agreement Subject to the exercise of the options contained in the ADCT Collaboration Agreement, the Group has granted ADC Therapeutics, with respect to each elected target, an exclusive, worldwide, perpetual and irrevocable (subject only to the termination provisions) license (with the right to grant sublicenses) to develop, make, use, commercialize and import the antibody drug conjugates that comprise masked antibodies generated by the Group under these programs. Under the ADCT License Agreement, if ADC Therapeutics exercises both of its options granted thereunder, the Group could be eligible to receive up to a low‑nine‑figure dollar amount in development and regulatory milestone payments upon the achievement of certain milestones (including milestones of successful completion of Good Laboratory Practice Toxicology studies, launch of clinical trials and start of commercial sales in difference countries and etc.) and up to a mid‑eight‑figure dollar amount in sales milestone payments, in addition to mid‑single‑digit percentage net sales‑based tiered royalties on products licensed under the ADCT License Agreement, subject to certain reductions. Royalties, if any, will be payable on a country‑by‑country and product‑by‑product basis, until the earlier of (i) the tenth anniversary of the first commercial sale of such product or (ii) the expiration of the last‑to‑expire patent licensed under the agreement in such country, unless earlier terminated by the parties, following which any licenses granted to ADC Therapeutics under the ADCT License Agreement shall become fully paid up, perpetual and irrevocable. ADC Therapeutics has the right to terminate the ADCT License Agreement before the expiration of the royalty term on a product‑by‑product basis or in its entirety (i) for any reason or no reason upon thirty days’ written notice to the Group, or (ii) if ADC Therapeutics chooses to discontinue the development or sale of the applicable licensed product worldwide. Each party has certain rights to terminate the ADCT License Agreement with prior written notice upon the other party’s uncured material breach or insolvency. For the year ended December 31, 2020, the Group recognized US$225,000 upon delivery of such results. For the year ended December 31, 2020, the Group recognized US$100,000 as other income due to the expiration of exclusive target reservation right, which is not related to the Group's major operation activity. |

In making such determination, the Group evaluates a variety of positive and negative factors including the Group’s operating history, accumulated deficit, the existence of taxable temporary differences and reversal periods. The Group has incurred net accumulated operating losses for income tax purposes since its inception. The Group believes that it is more likely than not that these net accumulated operating losses will not be utilized in the future. Therefore, the Group has provided full valuation allowances for the deferred tax assets as of December 31, 2019 and 2020.

RESTRICTED NET ASSETS | |
RESTRICTED NET ASSETS | 15. RESTRICTED NET ASSETS The Group’s ability to pay dividends may depend on the Group receiving distributions of funds from its PRC subsidiary. Relevant PRC statutory laws and regulations permit payments of dividends by the Group’s PRC subsidiary only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the consolidated financial statements prepared in accordance with U.S. GAAP differ from those reflected in the statutory financial statements of the Group’s PRC subsidiary. In accordance with the Company law of the PRC, a domestic enterprise is required to provide statutory reserves of at least 10% of its annual after‑tax profit until such reserve has reached 50% of its respective registered capital based on the enterprise’s PRC statutory accounts. A domestic enterprise is also required to provide discretionary surplus reserve, at the discretion of the Board of Directors, from the profits determined in accordance with the enterprise’s PRC statutory accounts. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. The Group’s PRC subsidiary was established as domestic invested enterprise and therefore is subject to the above mentioned restrictions on distributable profits. As of December 31, 2019 and 2020, the total restricted net assets of the Company’s subsidiary incorporated in PRC and subjected to restriction amounted to approximately US$1,267,900 and US$1,267,900, respectively. Other subsidiaries are not subjected to such restriction. As a result of these PRC laws and regulations subject to the limit discussed above that require annual appropriations of 10% of after‑tax income to be set aside, prior to payment of dividends, as general reserve fund, the Group’s PRC subsidiary is restricted in their ability to transfer a portion of their net assets to the Group. Foreign exchange and other regulations in the PRC further restrict the Company’s PRC subsidiaries from transferring funds to the Company in the form of dividends, loans and advances. Since the Group has a consolidated shareholders’ deficit, its net asset base for purposes of calculating the proportionate share of restricted net assets of consolidated subsidiaries should be zero. Therefore, the restrictions placed on the net assets of the Company’s PRC subsidiaries with positive equity would result in the 25 percent threshold being exceeded and a corresponding requirement to provide parent company financial information (Note 18). |

SUMMARY OF SIGNIFICANT ACCOUN_2
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
Dec. 31, 2020 | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
Basis of presentation | Basis of presentation The accompany consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements of the Group include the financial statements of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation. |
Use of estimates | Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in the Group’s consolidated financial statements include, but are not limited to, the useful lives and impairment of long‑lived assets, tax valuation allowance, share‑based compensation expenses and the fair value of warrant liabilities. Management bases the estimates on historical experience and various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could materially differ from those estimates. |
Foreign currency translation | Foreign currency translation The functional currency of the Company, Adagene (Hong Kong) Limited, Adagene Incorporated and Adagene PTE. Ltd. is the United States dollar (“US$”). The functional currency of the Company’s PRC subsidiary is Renminbi (“RMB”). The functional currency of the Company’s Australia subsidiary is Australian dollar (“AU$”). The functional currency of the Company’s Switzerland subsidiary is Swiss Franc (“CHF”). The determination of the respective functional currency is based on the criteria stated in Accounting Standard Codification (“ASC”) 830, Foreign Currency Matters . The Company uses US$ as its reporting currency. The financial statements of the Company’s PRC, Australia and Switzerland subsidiaries are translated from the functional currency to the reporting currency. Transactions denominated in foreign currencies are remeasured into the functional currency at the exchange rates quoted by the People’s Bank of China (the “PBOC”) prevailing on the transaction dates. Monetary assets and liabilities denominated in foreign currencies are re‑measured at the exchange rates prevailing at the balance sheet date. Non‑monetary items that are measured in terms of historical costs in foreign currency are re‑measured using the exchange rates at the dates of the initial transactions. Exchange gains and losses are included in the consolidated statements of comprehensive loss. 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 year. Translation adjustments are reported as accumulated comprehensive loss and are shown as a separate component of other comprehensive loss in the consolidated statements of comprehensive loss. |
Cash and cash equivalents | Cash and cash equivalents Cash and cash equivalents primarily consist of cash and demand deposits which are highly liquid. The Group considers highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of three months or less to be cash equivalents. All cash and cash equivalents are unrestricted as to withdrawal and use. |
Short-term investments | Short‑term investments Short‑term investments are deposits at bank with maturities of greater than three months, but less than twelve months. Short‑term investments are stated at cost, which approximates fair value. Interest earned is included in interest income. |
Accounts receivable and allowance for doubtful accounts | Accounts receivable and allowance for doubtful accounts Account receivable is recorded when the Group has an unconditional right to consideration. A right to consideration is unconditional if only the passage of time is required before payment of that consideration is due. Accounts receivable are carried at net realizable value. An allowance for doubtful accounts is recorded in the period when collection of the amount is no longer probable. In evaluating the collectability of receivable balances, the Group considers specific evidence including the aging of the receivable, the customer’s payment history, its current credit‑worthiness and other factors. Accounts receivable are written off when management determines a balance is uncollectable after all collection efforts have ceased. |
Fair value measurements | Fair value measurements The Group applies 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. ASC 820 requires disclosures to be provided for fair value measurements. ASC 820 establishes a three‑tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1—Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2—Includes other inputs that are directly or indirectly observable in the marketplace. Level 3—Unobservable inputs which are supported by little or no market activity. ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach; and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. The carrying amounts of cash and cash equivalent, short‑term investments, accounts receivable, amounts due to related parties and other current assets, accounts payable, amounts due to related parties, accrued liabilities and other current liabilities and short‑term borrowings approximate their fair values because of their generally short maturities. The carrying amount of long‑term borrowings approximate their fair values since they bear interest rates which approximate market interest rates. As more fully described in Note 8, the Group issued warrants to two Series C-1 preferred shareholders to purchase its preferred shares. The warrants have expired on April 1, 2019. The Group measured its warrant liabilities at fair value on a recurring basis. As the Group’s warrants are not traded in an active market with readily observable prices, the Group uses significant unobservable inputs to measure the fair value of warrant liabilities. These instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. The following table presents a reconciliation of all financial instruments measured at fair value on a recurring basis using Level 3 unobservable inputs: Warrant liabilities US$ Initial recognition during the year ended December 31, 2018 1,741,720 Fair value change (534,305) Balance as of December 31, 2018 1,207,415 Fair value change (1,207,415) Balance as of December 31, 2019 — The Group did not transfer any assets or liabilities in or out of Level 3 during the years ended December 31, 2018, 2019 and 2020. The Group had no financial assets and liabilities measured and recorded at fair value on a nonrecurring basis as of December 31, 2019 and 2020. |
Property, equipment and software | Property, equipment and software Property and equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight‑line method over the estimated useful lives of the assets as follows: Category Estimated Useful Life Machinery and laboratory equipment 5 years Vehicles 4 years Furniture and tools 3 - 5 years Electronic equipment 3 years Computer software 3 - 5 years Leasehold improvements Lesser of lease terms or estimated useful lives of the assets Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful lives of property, equipment and software are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation and amortization from the asset and accumulated depreciation and amortization accounts with any resulting gain or loss reflected in the consolidated statements of comprehensive loss. |
Impairment of long-lived assets | Impairment of long‑lived assets The Group evaluates the recoverability of its long‑lived assets, including fixed assets and intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. When these events occur, the Group measures impairment by comparing the carrying amount of the assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the assets over their fair value. Fair value is generally determined by discounting the cash flows expected to be generated by the assets, when the market prices are not readily available. The adjusted carrying amount of the assets is the new cost basis and is depreciated over the assets’ remaining useful lives. Long‑lived assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. No impairment loss was recorded for the years ended December 31, 2019 and 2020. |
Segment reporting | Segment reporting In accordance with ASC 280, Segment Reporting , the Group’s chief operating decision maker (“CODM”) has been identified as the Chief Executive Officer. The Group’s CODM reviews the consolidated results of operations when making decisions about allocating resources and assessing performance of the Group. The Group operates and manages it business as a single segment. No geographical segments are presented as substantially all of the Group’s long‑lived assets are located in the PRC. |
Revenue recognition | Revenue recognition At contract inception of collaboration and out‑licensing arrangements, the Group analyzes its arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Group first determines which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are reflective of a vendor‑customer relationship and therefore within the scope of ASC 606. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied consistently. Under the criteria of Accounting Standard Codification (“ASC”) 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”), the Group recognizes revenue to depict the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to receive in exchange for those goods or services. The Group adopted ASC 606 for all periods presented. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Group only applies the five‑step model to contracts when it is probable that the entity will collect substantially all the consideration to which it is entitled in exchange for the goods or services it transfers to the customer. The Group reviews the contract to determine which performance obligations are distinct and represent a promise to provide distinct goods or services or a series of distinct goods or services as defined by the standard. The Group recognizes as revenue the amount of the transaction price that is allocated to each performance obligation as and when that performance obligation is satisfied. Licenses of Intellectual Property: Upfront non‑refundable payments for licensing the Group’s intellectual property are evaluated to determine if the license is distinct from the other performance obligations identified in the arrangement. For licenses determined to be distinct, the Group recognizes revenues from non‑refundable, up‑front fees allocated to the license at a point in time, when the transfer of control of the license to the licensee occurs and the licensee is able to use and benefit from the license. Milestone Payments: At the inception of each arrangement that includes development, commercialization, and regulatory milestone payments, the Group evaluates whether the milestones are considered probable of being reached and to the extent that a significant reversal of cumulative revenue would not occur in future periods, estimates the amount to be included in the transaction price using the most likely amount method. The transaction price is then allocated to each performance obligation on a relative stand‑alone selling price basis, for which the Group recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Group re‑evaluates the probability of achieving such development milestones and any related constraint, and if necessary, adjust the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch‑up basis, which would affect revenues and earnings in the period of adjustment. Royalties: For arrangements that include sales‑based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Group recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, no milestone payments or royalty payments were received. Substantially all of the Group’s revenue has been derived from its out‑licensing agreements with respect to licensed products such as DNA sequences, cell lines, etc., and such revenues are recognized when the customer obtains control of the licensed product, which occurs at a point in time, upon delivery to the customer. Contract assets and contract liabilities When a customer pays consideration before the Group transfers products or services, the Group records its obligation as a contract liability; When the Group satisfies its performance obligations by providing products or services to a customer before the customer pays consideration and before payment is due, the Group recognizes its rights to consideration as a contract asset. |
Research and development expenses | Research and development expenses Elements of research and development expenses primarily include (1) payroll and other related costs of personnel engaged in research and development activities, (2) costs related to pre‑clinical testing of the Group’s technologies under development and clinical trials such as payments to contract research organizations (“CRO”) and contract manufacturing organizations (“CMO”), investigators and clinical trial sites that conduct the clinical studies; (3) costs to develop the product candidates, including raw materials and supplies, product testing, depreciation and amortization, and facility related expenses, (4) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to the Group’s research and development services and have no alternative future uses. As of December 31, 2020, the Group has several ongoing clinical studies in various clinical trial stages. The contracts with CRO and CMO are generally cancellable, with notice, at the Group’s option. The Group did not record any accrued expenses related to cancellation of CRO or CMO contracts as of December 31, 2020 as the Group did not have any plan to cancel the existing CRO or CMO contracts. |
Government subsidies | Government subsidies Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the governments. The Group’s PRC based subsidiary received government subsidies from certain local government. The Group’s government subsidies consist of specific subsidies and other subsidies. Specific subsidies are subsidies that the local government has set certain conditions for the subsidies. Other subsidies are the subsidies that the local government has not set any conditions and are not tied to future trends or performance of the Group, receipt of such subsidy income is not contingent upon any further actions or performance of the Group and the amounts do not have to be refunded under any circumstances. The Group recorded specific subsidies as other non‑current liabilities when received and recognized as other income when the conditions are met. Other subsidies are recognized as other income upon receipt as further performance by the Group is not required. |
Leases | Leases Leases are classified at the inception date as either a capital lease or an operating lease. The Group assesses a lease to be 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 on a straight‑line basis over their respective lease terms. The Group leases certain office space under non‑cancelable operating lease agreements. Certain lease agreements contain rent holidays. Rent holidays are considered in determining the straight‑line rent expense to be recorded over the lease term. The lease term begins on the date of initial possession of the leased property for purpose of recognizing lease expense on straight‑line basis over the term of the lease. |
Comprehensive loss | Comprehensive loss Comprehensive loss is defined as the changes in equity of the Group during a period from transactions and other events and circumstances excluding transactions resulting from investments by shareholders and distributions to shareholders. Accumulated other comprehensive loss of the Group includes foreign currency translation adjustments related to the Group and its subsidiaries whose functional currency is not US$. |
Income taxes | Income taxes The Group follows the liability method of accounting for income taxes in accordance with ASC 740, Income Taxes (“ASC 740”). Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rate is recognized in tax expense in the period that includes the enactment date of the change in tax rate. The Group evaluates its uncertain tax positions using the provisions of ASC 740, which prescribes a recognition threshold that a tax position is required to meet before being recognized in the consolidated financial statements. The Group recognizes in the consolidated financial statements the benefit of a tax position which is “more likely than not” to be sustained under examination based solely on the technical merits of the position assuming a review by tax authorities having all relevant information. Tax positions that meet the recognition threshold are measured using a cumulative probability approach, at the largest amount of tax benefit that has a greater than fifty percent likelihood of being realized upon settlement. It is the Group’s policy to recognize interest and penalties related to unrecognized tax benefits, if any, as a component of income tax expense. |
Borrowings | Borrowings Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the consolidated statements of comprehensive loss over the period of the borrowings using the effective interest method. |
Share-based compensation | Share‑based compensation The Company grants restricted shares and stock options to eligible employees and nonemployees and accounts for share-based compensation in accordance with ASC 718, Compensation—Stock Compensation. Share-based compensation awards are measured at the grant date fair value of the awards and recognized as expenses a) immediately at the grant date if no vesting conditions are required; or b) for share-based awards granted with only service conditions, using the straight-line method over the vesting period; or c) for share-based awards granted with service conditions and performance conditions, using the graded vesting method over the vesting period if and when the company concludes that it is probable that the performance conditions will be achieved. A change in any of the terms or conditions of share-based awards is accounted for as a modification of the awards. The Group calculates incremental compensation expense of a modification as the excess of the fair value of the modified awards over the fair value of the original awards immediately before its terms are modified at the modification date. For vested awards, the Group recognizes incremental compensation cost in the period when the modification occurs. For awards not being fully vested, the Group recognizes the sum of the incremental compensation expense and the remaining unrecognized compensation expense for the original awards over the remaining requisite service period after modification. |
Net loss per share | Net loss per share In accordance with ASC 260, Earnings Per Share , basic net loss per share is computed by dividing net loss attributable to ordinary shareholders by the weighted average number of unrestricted ordinary shares outstanding during the year using the two‑class method. Under the two‑class method, net loss is allocated between ordinary shares and other participating securities based on dividends declared (or accumulated) and participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed. The Company’s convertible redeemable preferred shares are participating securities because they are entitled to receive dividends or distributions on an as converted basis. Diluted net loss per share is calculated by dividing net loss 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 period. Ordinary equivalent shares include ordinary shares issuable upon the conversion of the convertible redeemable preferred shares using the if‑converted method, and ordinary shares issuable upon the exercise of share options, using the treasury stock method. Ordinary share equivalents are excluded from the computation of diluted earnings per share if their effects are anti‑dilutive. For the periods presented herein, the computation of basic net loss per share using the two‑class method is not applicable as the Group is in a net loss position and the participating securities do not have contractual rights and obligations to share in the losses of the Group. |
Employee defined contribution plan | Employee defined contribution plan As stipulated by the regulations of the PRC, full‑time employees of the Group are entitled to staff welfare benefits including medical care, welfare subsidies, unemployment insurance and pension benefits through a PRC government‑mandated multi‑employer defined contribution plan. The Group is required to accrue for these benefits based on certain percentages of the qualified employees’ salaries. The Group is required to make contributions to the plans out of the amounts accrued. The PRC government is responsible for the medical benefits and the pension liability to be paid to these employees and the Group’s obligations are limited to the amounts contributed. The Group has no further payment obligations once the contributions have been paid. The Group recorded employee benefit expenses of US$1,145,165 and US$622,377 for the years ended December 31, 2019 and 2020, respectively. |
Concentration of risks | Concentration of risks Concentration of credit risk As of December 31, 2019 and 2020, the aggregate amount of cash and cash equivalents and short‑term investments of US$801,923 and US$3,424,456 respectively, were held at major financial institutions located in the mainland of China, and US$99,730,865 and US$71,726,542, respectively, were deposited with major financial institutions located outside the mainland of China. Management believes that these financial institutions are of high credit quality and continually monitors the credit worthiness of these financial institutions. Accounts receivable are typically unsecured and denominated in US$ and are derived from revenues earned from customers. The Group manages credit risk of accounts receivable through ongoing monitoring of the outstanding balances. Concentration of suppliers A significant portion of the Group’s research and development services were purchased from its one supplier, who collectively accounted for 23.13% and 21.51% of the Group’s total research and development services purchases for the years ended December 31, 2019 and 2020, respectively. Business and economic risk The Group believes that changes in any of the following areas could have a material adverse effect on the Group’s future consolidated financial position, results of operations or cash flows: changes in the overall demand for services; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in certain strategic relationships; regulatory considerations and risks associated with the Group’s ability to attract employees necessary to support its growth. The Group’s operations could also be adversely affected by significant political, regulatory, economic and social uncertainties in the PRC. Foreign currency exchange rate risk A significant portion of the Group’s businesses are transacted in RMB, which is not a freely convertible currency. On January 1, 1994, the PRC government abolished the dual rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts. From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. For U.S. dollar against RMB, there was appreciation and depreciation of approximately 1.3% and 6.5% in the years ended December 31, 2019 and 2020, respectively. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future. The functional currency and the reporting currency of the Company are the US$. However, large portion of the expenses of the Group are denominated in RMB. Any significant fluctuation of the valuation of RMB may materially affect the Group’s cash flows, expenses, losses and financial position, and the value of any dividends payable on the American Depositary Shares in US$. |
Recently issued accounting pronouncements | Recently issued accounting pronouncements The Group is an emerging growth company (“EGC”) as defined by the Jumpstart Our Business Startups Act (“JOBS Act”). The JOBS Act provides that an EGC can take advantage of extended transition periods for complying with new or revised accounting standards. This allows an EGC to delay adoption of certain accounting standards until those standards would otherwise apply to private companies. The Group elected to take advantage of the extended transition periods. However, this election will not apply should the Group cease to be classified as an EGC. In February 2016, the FASB issued ASU No. 2016‑02 (“ASU 2016‑02”), Leases (Topic 842), which modifies lease accounting for lessees to increase transparency and comparability by recording lease assets and liabilities for operating leases and disclosing key information about leasing arrangements. In July 2018, the FASB issued ASU No. 2018‑10 (“ASU 2018‑10”), Codification Improvements to Topic 842, Leases, which clarifies certain aspects of the guidance issued in ASU 2016‑02; and ASU No. 2018‑11 (“ASU 2018‑11”), Leases (Topic 842): Targeted Improvements, which provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative‑effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases). Further, the FASB issued ASU No. 2020-05 (“ASU 2020-05”), Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities, which extends the adoption date for certain entities. For the Group, the updated guidance is effective for fiscal years beginning after December 15, 2021 and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. The Group does not plan to early adopt the new lease standards and the Group expects that applying the ASU 2016‑02 would materially increase the assets and liabilities due to the recognition of right‑of‑use assets and lease liabilities on its consolidated balance sheets, with an immaterial impact on its consolidated statements of comprehensive loss and consolidated statements of cash flows. In June 2016, the FASB issued ASU No. 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016‑13”). ASU 2016‑13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. This ASU requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of the Group’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. In November 2019, the FASB issued ASU 2019‑10, which extends the adoption date for certain registrants. The amendments in ASU 2016‑13 are effective for fiscal years beginning after December 15, 2022, including interim periods within fiscal years beginning after December 15, 2023. The Group does not plan to early adopt ASU 2016‑13 and is currently in the process of evaluating the impact of adoption of this guidance on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018‑07, Compensation—Stock Compensation (Topic 718): Improvements to nonemployee share‑based payment accounting (“ASU 2018‑07”). The amendments in this update expand the scope of Topic 718 to include share‑based payment transactions for acquiring goods and services from nonemployees. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Group adopted on January 1, 2018 this guidance which do not have a significant impact on the consolidated financial statements. In August 2018, the FASB issued ASU No. 2018‑13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018‑13”). ASU 2018‑13 modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The amendments in ASU 2018‑13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018‑13. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018‑13 and delay adoption of the additional disclosures until their effective date. The Group elected to early adopt this ASU and applied this guidance retrospectively to all periods presented. The impact of this ASU to the consolidated financial statements is immaterial. In November 2018, the FASB issued ASU 2018‑18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This update clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer and precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The update is effective in fiscal years beginning after December 15, 2021, and interim periods therein, and early adoption is permitted for entities that have adopted ASC 606. This guidance should be applied retrospectively to the date of initial application of Topic 606. The Group elected to early adopt this ASU and applied this guidance retrospectively to all periods presented. The impact of this ASU to the consolidated financial statements is immaterial. In December 2019, the FASB issued ASU 2019‑12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This update simplifies the accounting for income taxes as part of the FASB’s overall initiative to reduce complexity in accounting standards. The amendments include removal of certain exceptions to the general principles of ASC 740, Income taxes , and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. The update is effective in fiscal years beginning after December 15, 2022, and interim periods therein, and early adoption is permitted. Certain amendments in this update should be applied retrospectively or modified retrospectively, all other amendments should be applied prospectively. The Group does not plan to early adopt ASU 2019‑12 and is currently evaluating the impact on its financial statements of adopting this guidance. In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity, which simplifies the accounting for convertible instruments by removing certain separation models in Subtopic 470-20, Debt-Debt with Conversion and Other Options, for convertible instruments and also increases information transparency by making disclosure amendments. The standard is effective for private companies for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of this accounting standard update on its condensed consolidated financial statements. |
