[1] In May 2012, Foxtel purchased Austar United Communications Ltd. The transaction was funded by Foxtel bank debt and Foxtel's shareholders made pro rata capital contributions in the form of subordinated shareholder notes based on their respective ownership interests. The Company's share of the subordinated shareholder notes was approximately A$451 million ($425 million and $412 million as of June 30, 2014 and 2013, respectively). 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.
