Contingent liabilities

   
  A contingent liability is a possible obligation that arises from past events, the existence of which will be confirmed only by the occurrence or non-occurrence of one or more uncertain future events not wholly within the control of the group, or a present obligation that arises from past events but is not recognised because it is not probable that an outflow of resources embodying economic benefits will be required to settle the obligation, or the amount of the obligation cannot be measured with sufficient reliability. Contingent liabilities are not recognised as liabilities in the statement of financial position but disclosed in the notes to the financial statements.
