[1] In connection with the Separation, as defined in Note 10, Twenty-First Century Fox, Inc. ("21st Century Fox") sold 4,000 shares of cumulative redeemable preferred stock with a par value of $5,000 per share of a newly formed U.S. subsidiary of the Company. The preferred stock pays dividends at a rate of 9.5% per annum, payable quarterly. The preferred stock is callable by the Company at any time after the fifth year and is puttable at the option of the holder after 10 years.

[2] The dilutive impact of the Company's PSUs, RSUs and stock options have been excluded from the calculation of diluted (loss) earnings per share for the three and six months ended December 31, 2016 because their inclusion would have an antidilutive effect on the net loss per share.
