[1] In accordance with ASC 350, the Company amortized $19 million and $12 million, respectively, related to excess cost over the Company's proportionate share of its investment's underlying net assets allocated to finite-lived intangible assets during the three months ended September 30, 2016 and 2015. Such amortization is reflected in Equity (losses) earnings of affiliates in the Statements of Operations. The increase in amortization expense recognized by the Company in the current year period was offset by a corresponding decrease in amortization expense recognized by Foxtel as certain intangible assets were fully amortized in fiscal 2016.
