The Group has recognized the net assets of Han Xiang on a historical cost with no change in basis in the consolidated financial statements upon the completion of the reorganization. The shareholders’ rights and obligations remained the same after the reorganization.

On October 2, 2018 the Group completed its initial public offering (“IPO”) in the United States and issued 4,350,000 American depositary shares representing 217,500,000 of the Group’s ordinary shares. Net proceeds from the IPO after deducting underwriting discount and offering costs were US$45.1 million.
