Share based compensation plan description           In September 2020, immediately prior to the IPO, the Company adopted the 2020 Plan. Following the effectiveness of the 2020 Plan, the Company will no longer grant any awards under the 2011 Plan, though previously granted options under the 2011 Plan remain outstanding and governed by the 2011 Plan. The 2020 Plan provides for the grant of share options, ordinary shares, restricted shares, restricted share units and other share-based awards. The maximum number of ordinary shares available for issuance under the 2020 Plan is equal to the sum of (i) 9,100,000 ordinary shares plus, (ii) any shares subject to the pool authorized by the Company’s board of directors under the 2011 Plan which remain free and unallocated as of the effective date, and (iii) any shares subject to awards granted under the 2011 Plan that, on or after the effective date, expire, or are cancelled, terminated, forfeited or settled in cash in lieu of issuance of shares, for any reason, without having been exercised, with the maximum number of shares to be added to the 2020 Plan pursuant to the 2011 Plan equal to 15,309,367 shares.        
Share based compensation plan modifications description           In addition, the number of shares available for issuance under the Company’s 2020 Plan also includes an annual increase on January 1 of each year beginning on January 1, 2021 and ending on and including January 1, 2030, in an amount equal to the least of (i) 9,100,000 ordinary shares, (ii) five percent (5%) of the total number of ordinary shares outstanding as of the last day of the immediately preceding calendar year on a fully diluted basis, or (iii) such number of shares determined by the Company’s board of directors.
