From time to time, the Group is involved in claims and legal proceedings that arise in the ordinary course of business. Based on currently available information, management does not believe that the ultimate outcome of these unresolved matters, individually and in the aggregate, is likely to have a material adverse effect on the Group’s financial position, results of operations or cash flows.

However, litigation is subject to inherent uncertainties and the Group’s view of these matters may change in the future. If an unfavorable outcome were to occur, there exists the possibility of a material adverse impact on the Group’s financial position and results of operations for the periods in which the unfavorable outcome occurs.
