14. | CONVERTIBLE REDEEMABLE PREFERRED SHARES (CONTINUED)
Conversion rights Optional conversion Each Series A, B, C, D, E and F Preferred Share shall be convertible, at the option of the holder thereof, at any time and without the payment of additional consideration by the holder thereof, into such number of Class A ordinary shares as determined by the quotient of the applicable issue price divided by the then effective applicable conversion price with respect to such particular series of Preferred Shares, which shall initially be the applicable issue price for the Series A, B, C, D, E and F Preferred Shares, as the case may be, resulting in an initial conversion ratio for the Preferred Shares of 1:1, and shall be subject to adjustment and readjustment from time to time, including but not limited to additional equity securities issuances, share dividends, distributions, subdivisions, redemptions, combinations, or reorganizations, mergers, consolidations, reclassifications, exchanges or substitutions. Automatic conversion Each Preferred Share is convertible, at the option of the holder, at any time after the date of issuance of such Preferred Shares according to a conversion ratio, subject to adjustments for dilution, including but not limited to stock splits, stock dividends and capitalization and certain other events. Each Preferred Share is convertible into a number of ordinary shares determined by dividing the applicable original issue price by the conversion price (initially being 1 to 1 conversion ratio). The conversion price of each Preferred Share is the same as its original issue price and no adjustments to conversion price have occurred so far. Each Series A, B, C, D, E and F Preferred Share shall automatically be converted into Class A ordinary shares, at the then applicable preferred share conversion price upon (i) closing of a Qualified Initial Public Offering (“Qualified IPO”), or (ii) the written approval of the holders of a majority of each series of Preferred Shares (calculated and voting separately in their respective single class on an as-converted basis). Prior to the Series D Preferred Shares issuance on November 2, 2017, a “Qualified IPO” was defined as an initial public offering with gross proceeds no less than US$60 million and capitalization of the Company of no less than US$350 million prior to such initial public offering. Upon the issuance of Series D Preferred Shares, the gross proceeds and market capitalization criteria for a “Qualified IPO” were increased to US$90 million and US$900 million, respectively. Upon the issuance of Series E Preferred Shares, the gross proceeds and market capitalization criteria for a “Qualified IPO” were increased to US$100 million and US$2,000 million, respectively. Upon the issuance of Series F Preferred Shares, the gross proceeds and market capitalization criteria for a “Qualified IPO” were increased to US$100 million and US$3,300 million, respectively. Upon the issuance of Series F-plus Preferred Shares, the gross proceeds and market capitalization criteria for a “Qualified IPO” were increased to US$300 million and US$5,000 million, respectively. Voting rights Each holder of Series A, B, C, D, E and F Preferred Shares is entitled to cast the number of votes equal to the number of Class A ordinary shares such Preferred Shares would be entitled to convert into at the then effective conversion price. There was a modification to the voting rights of the shares controlled by Mr. Peng Zhao when the Series F and Series F-plus Preferred Shares were issued as follows:
| ● | the voting rights of ordinary shares controlled by Mr. Peng Zhao was modified to carry 10 votes in connection with the Series F Preferred Shares financing; and
| ● | the voting rights of shares controlled by Mr. Peng Zhao was modified to carry 15 votes in connection with the Series F-plus Preferred Shares financing.
​
14. | CONVERTIBLE REDEEMABLE PREFERRED SHARES (CONTINUED)
Dividend rights Each Preferred Share shall have the right to receive dividends, on an as-converted basis, when, as and if declared by the Board. No dividend shall be paid on the ordinary shares at any time unless and until all dividends on the Preferred Shares have been paid in full. No dividends on preferred and ordinary shares have been declared since the issuance date. Liquidation preference In the event of any liquidation (unless waived by the majority of Preferred Shareholders) including deemed liquidation, dissolution or winding up of the Company, Preferred Shareholders shall be entitled to receive a per share amount equal to 100% of the original preferred share issue price of the respective series of Preferred Shares, as adjusted for share dividends, share splits, combinations, recapitalizations or similar events, plus all accrued and declared but unpaid dividends thereon, in the sequence of Series F Preferred Shares, Series E Preferred Shares, Series D Preferred Shares, Series C Preferred Shares, Series B Preferred Shares, and Series A Preferred Shares. After such liquidation 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, pari passu basis among the holders of the Preferred Shares, on an as-converted basis, together with the holders of the ordinary shares. Redemption rights At any time commencing on a date specified in the shareholders’ agreements (the “Redemption Start Date”), holders of majority (more than 50%) of the then outstanding Series A, B, C, D, E and F Preferred Shares may request a redemption of the Preferred Shares of such series. On receipt of a redemption request from the holders, the Company shall redeem all or part, as requested, of the outstanding Preferred Shares of such series. The Redemption Start Date of Preferred Shares have been amended for a number of times historically. If any holder of any series of Preferred Shares exercises its redemption right, any holder of other series of Preferred Shares shall have the right to exercise the redemption of its series at the same time. The redemption prices have been modified historically. Prior to the issuance of Series F Preferred Shares, the price at which each Preferred Share shall be redeemed shall equal to the original Preferred Shares issue price for such series plus 10% compound interest per annum (calculated from the issuance date of the respective series of Preferred Shares), and declared but unpaid dividends. Upon the issuance of Series F Preferred Shares, the price at which each Preferred Share shall be redeemed shall equal to the original Preferred Shares issue price for such series plus 8% simple interest per annum (calculated from the issuance dates of the respective series of Preferred Shares), and declared but unpaid dividends. If on the redemption date triggered by the occurrence of any redemption event, the Company’s assets or funds which are legally available are insufficient to pay in full the aggregate redemption price for Preferred Shares requested to be redeemed, upon the request of a redeeming shareholder, the Company shall execute and deliver a two-year note, bearing an interest of ten percent (10%) per annum and with repayment of the principal and interest to be made on a monthly basis over a period of twenty-four (24) months. Preferred Shares subject to redemption with respect to which the Company has become obligated to pay the redemption price but which it has not paid in full shall continue to have all the rights and privileges which such Preferred Shareholders had prior to such date, until the redemption price has been paid in full with respect to such Preferred Shares. Conversion upon IPO In June 2021, upon the completion of IPO, all of the Preferred Shares were automatically converted to 551,352,134 Class A ordinary shares on a one-for-one basis. ​
14. | CONVERTIBLE REDEEMABLE PREFERRED SHARES (CONTINUED)
Accounting for preferred shares The Company classified the Preferred Shares in the mezzanine equity section of the Consolidated Balance Sheets because they were redeemable at the holders’ option any time after a certain date and were contingently redeemable upon the occurrence of certain liquidation event outside of the Company’s control. The Preferred Shares are recorded initially at fair value, net of issuance costs. The Company records accretion on the Preferred Shares, where applicable, to the redemption value from the issuance dates to the earliest redemption dates. The accretion, calculated using the effective interest method, is recorded against retained earnings, or in the absence of retained earnings, by charging against additional paid-in capital. Once additional paid-in capital has been exhausted, additional charges are recorded by increasing the accumulated deficit. The accretion of Preferred Shares was RMB164,065 (US$25,284) for the six months ended June 30, 2021. The Company has determined that, under the whole instrument approach, host contract of the Preferred Shares is more akin to a debt host, given the Preferred Shares holders have potential creditors’ right in the event of insufficient fund upon redemption, along with other debt-like features in the terms of the Preferred Shares, including the redemption rights. However, the Company determined that the embedded feature, including conversion feature, do not require bifurcation as they either are clearly and closely related to the host or do not meet definition of a derivative. The Company has determined that there was no beneficial conversion feature attributable to all Preferred Shares because the initial effective conversion prices of these Preferred Shares were higher than the fair value of the Company’s ordinary shares determined by the Company with the assistance from an independent third-party appraiser. Modification of preferred shares The Company assesses whether an amendment to the terms of its convertible redeemable preferred shares is an extinguishment or a modification based on a qualitative evaluation of the amendment. If the amendment adds, removes, significantly changes to a substantive contractual term or to the nature of the overall instrument, the amendment results in an extinguishment of the preferred shares. The Company also assess if the change in terms results in value transfer between Preferred Shareholders or between Preferred Shareholders and ordinary shareholders. When convertible redeemable preferred shares are extinguished, the difference between the fair value of the consideration transferred to the convertible redeemable Preferred Shareholders and the carrying amount of such preferred shares (net of issuance costs) is treated as a deemed dividend to the Preferred Shareholders. When convertible redeemable preferred shares are modified and such modification results in value transfer between Preferred Shareholders and ordinary shareholders, the change in fair value resulted from the amendment is treated as a deemed dividend to or from the Preferred Shareholders. Preferred shares modification were mainly included below:
| ● | Starting from the issuance of Series C Preferred Shares, optional redemption date of each pre-existing Preferred Shares was modified and extended to the fifth anniversary of each newly issued series of Preferred Shares applicable closing date; and
| ● | On February 10, 2020, the Redemption Start Date of Series A, B, C, D and E Preferred Shares was extended from July 5, 2024 to February 10, 2025, which is to be in line with the optional redemption date of Series F Preferred Shares. In the meanwhile, redemption price interest rate was lowered from 10% compound interest per annum to 8% simple interest per annum commencing from Series F Preferred Shares original issuance date and ending on the date of redemption.
From both quantitative and qualitative perspectives, the Company assessed the impact of these modifications and concluded that they represented a modification rather than extinguishment of pre-existing preferred shares, and the impact of the modification was immaterial.

If on the redemption date triggered by the occurrence of any redemption event, the Company’s assets or funds which are legally available are insufficient to pay in full the aggregate redemption price for Preferred Shares requested to be redeemed, upon the request of a redeeming shareholder, the Company shall execute and deliver a two-year note, bearing an interest of ten percent (10%) per annum and with repayment of the principal and interest to be made on a monthly basis over a period of twenty-four (24) months. Preferred Shares subject to redemption with respect to which the Company has become obligated to pay the redemption price but which it has not paid in full shall continue to have all the rights and privileges which such Preferred Shareholders had prior to such date, until the redemption price has been paid in full with respect to such Preferred Shares. Conversion upon IPO In June 2021, upon the completion of IPO, all of the Preferred Shares were automatically converted to 551,352,134 Class A ordinary shares on a one-for-one basis. Accounting for preferred shares The Company classified the Preferred Shares in the mezzanine equity section of the consolidated balance sheets because they were redeemable at the holders’ option any time after a certain date and were contingently redeemable upon the occurrence of certain liquidation event outside of the Company’s control. The Preferred Shares are recorded initially at fair value, net of issuance costs. ​

The Company records accretion on the Preferred Shares, where applicable, to the redemption value from the issuance dates to the earliest redemption dates. The accretion, calculated using the effective interest method, is recorded against retained earnings, or in the absence of retained earnings, by charging against additional paid-in capital. Once additional paid-in capital has been exhausted, additional charges are recorded by increasing the accumulated deficit. The accretion of Preferred Shares was RMB164,065 (US$25,284) for the nine months ended September 30, 2021. The Company has determined that, under the whole instrument approach, host contract of the Preferred Shares is more akin to a debt host, given the Preferred Shares holders have potential creditors’ right in the event of insufficient fund upon redemption, along with other debt-like features in the terms of the Preferred Shares, including the redemption rights. However, the Company determined that the embedded feature, including conversion feature, do not require bifurcation as they either are clearly and closely related to the host or do not meet definition of a derivative. The Company has determined that there was no beneficial conversion feature attributable to all Preferred Shares because the initial effective conversion prices of these Preferred Shares were higher than the fair value of the Company’s ordinary shares determined by the Company with the assistance from an independent third-party appraiser. Modification of preferred shares The Company assesses whether an amendment to the terms of its convertible redeemable preferred shares is an extinguishment or a modification based on a qualitative evaluation of the amendment. If the amendment adds, removes, significantly changes to a substantive contractual term or to the nature of the overall instrument, the amendment results in an extinguishment of the preferred shares. The Company also assess if the change in terms results in value transfer between Preferred Shareholders or between Preferred Shareholders and ordinary shareholders. When convertible redeemable preferred shares are extinguished, the difference between the fair value of the consideration transferred to the convertible redeemable Preferred Shareholders and the carrying amount of such preferred shares (net of issuance costs) is treated as a deemed dividend to the Preferred Shareholders. When convertible redeemable preferred shares are modified and such modification results in value transfer between Preferred Shareholders and ordinary shareholders, the change in fair value resulted from the amendment is treated as a deemed dividend to or from the Preferred Shareholders. Preferred shares modification were mainly included below:
| ● | Starting from the issuance of Series C Preferred Shares, optional redemption date of each pre-existing Preferred Shares was modified and extended to the fifth anniversary of each newly issued series of Preferred Shares applicable closing date; and
| ● | On February 10, 2020, the Redemption Start Date of Series A, B, C, D and E Preferred Shares was extended from July 5, 2024 to February 10, 2025, which is to be in line with the optional redemption date of Series F Preferred Shares. In the meanwhile, redemption price interest rate was lowered from 10% compound interest per annum to 8% simple interest per annum commencing from Series F Preferred Shares original issuance date and ending on the date of redemption.
From both quantitative and qualitative perspectives, the Company assessed the impact of these modifications and concluded that they represented a modification rather than extinguishment of pre-existing preferred shares, and the impact of the modification was immaterial.
