The subordinated shareholder note can be repaid beginning in July 2022 provided that Foxtel's senior debt has been repaid. The subordinated shareholder note has a maturity date of July 15, 2027, with interest of 12% payable on June 30 each year and at maturity. Upon maturity, the principal advanced will be repayable.
