The Group is subject to legal and regulatory actions that arise from time to time. The assessment as to whether a loss is probable or reasonably possible, and as to whether such loss or a range of such loss is estimable, often involves significant judgment about future events, and the outcome of litigation is inherently uncertain. The Group is currently not in any legal or administrative proceedings that may have a material adverse impact on the financial position, results of operations or cash flows of the Group.
