Unusual or Infrequent Item, or Both, Nature of Event or Transaction | On January 29, 2020, the Special Director issued an order imposing a penalty on YRIPL and certain former directors of approximately Indian Rupee 11 billion, or approximately $156 million. Of this amount, approximately $150 million relates to the alleged failure to invest a total of $80 million in India within an initial seven year period. We have been advised by external counsel that the order is flawed and that several options for appeal exist. We deny liability and intend to continue vigorously defending this matter. We do not consider the risk of any significant loss arising from this order to be probable. |
