[1] For the fiscal years ended June 30, 2014 and 2013, the Company received dividends from Foxtel of $151 million and $159 million, respectively. The Company's investment in Foxtel exceeds its equity in the underlying net assets by approximately $2.1 billion as of June 30, 2014. This amount represented the excess cost over the Company's proportionate share of its investment's underlying net assets. This has been allocated between finite-lived intangible assets, indefinite-lived intangible assets and goodwill. The finite-lived intangible assets of approximately $0.7 billion primarily represent subscriber relationships with a weighted remaining average useful life of 8 years.
