[1] Following completion of the Transaction in April 2018, News Corp ceased accounting for Foxtel as an equity method investment and began consolidating its results in the fourth quarter of fiscal 2018. See Note 3- Acquisitions, Disposals and Other Transactions. In accordance with ASC 350, "Intangibles-Goodwill and Other", the Company amortized $17 million 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, 2017. Such amortization is reflected in Equity losses of affiliates in the Statement of Operations.

[2] Other equity affiliates, net for the three months ended September 30, 2018 and 2017 include losses primarily from the Company's interest in Elara.
