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 $150 million. Of this amount, $145 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 have filed a writ petition with the Delhi High Court, which granted an interim stay of the penalty order on March 5, 2020. The stay order remains in effect and the next hearing is now scheduled for March 4, 2022. 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.
