[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 ($338 million and $345 million as of June 30, 2016 and June 30, 2015, respectively). The subordinated shareholder notes can be repaid beginning in July 2022 provided that Foxtel's senior debt has been repaid. The subordinated shareholder notes have a maturity date of July 15, 2027, with interest payable on June 30 each year and at maturity. On June 22, 2016, Foxtel and Foxtel's shareholders agreed to modify the terms of the loan receivable to reduce the interest rate from 12% to 10.5%, to more closely align with current market rates. Foxtel paid interest at a rate of 10.5% for fiscal 2016. Upon maturity, the principal advanced will be repayable.
