[1] Other receivables include the receivable insurance recoveries from the insurer resulted from the putative securities class action filed on April 17, 2020 in the U.S. District Court for the District of New Jersey, in which the Group and certain of its officers have been named as defendants. The action alleges that the Group made false and misleading statements regarding the Group’s business and operations in violation of the federal securities laws. On February 19, 2026, the Court granted preliminary approval of the settlement and set the Settlement Hearing for June 4, 2026. In accordance with the agreed settlement amount with the Plaintiffs, the Group has recognized USD9,500 receivable from the insurer and a corresponding USD9,500 payable to the Plaintiffs.
