Contingent liabilities

The Group has been named in a number of lawsuits arising in its ordinary course of business. Although the outcome of those lawsuits are uncertain, the Group does not believe the possibility of loss is probable. The Group is unable to estimate a range of loss, if any, that could result if there would be an adverse decision, as such, and the Group has not accrued any liabilities.
