[1] The Company recorded a tax benefit, net of applicable taxes on interest, of $721 million for the fiscal year ended June 30, 2014 to Income tax benefit in the Statements of Operations related to certain foreign tax refunds received. See the discussion of Foreign Tax Refund above. The tax benefit related to these refunds increased our effective tax rate 182%. These foreign tax refunds received were remitted to 21st Century Fox, net of applicable taxes on interest, in accordance with the terms of the Tax Sharing and Indemnification Agreement. Accordingly, for the fiscal year ended June 30, 2014, the Company recorded an expense to Other, net of approximately $721 million for the payment to 21st Century Fox in the Statements of Operations. This expense is a non-deductible item the tax effect of which is approximately $252 million and reflected as a decrease of approximately 64% in our effective tax rate.

[4] For the fiscal year ended June 30, 2015, the effective tax rate of 239% represents an income tax expense when compared to consolidated pre-tax book income. For the fiscal year ended June 30, 2014, the effective tax rate of 174% represents an income tax benefit when compared to consolidated pre-tax book loss. As a result, certain reconciling items between the U.S. federal income tax rate and the Company's effective tax rate may have the opposite impact. For the fiscal year ended June 30, 2013, the negative effective tax rate results from the Company's total tax benefit when compared to pre-tax book income. Further, reconciling items for the fiscal years ended June 30, 2015 and June 30, 2013, have a greater percentage impact on the Company's effective tax rate due to the comparatively low amount of consolidated pre-tax book income.

[5] The Company recognized a non-recurring pre-tax gain of approximately $1.3 billion associated with the acquisition of CMH resulting in a 247% reduction in our effective tax rate in the fiscal year ended June 30, 2013. The gain recognized on the acquisition of CMH does not give rise to taxable income and was a result of revaluing the Company's non-controlling interest to fair value as of the acquisition date in addition to the reversal of the historic deferred tax liability related to the consolidation of FOX SPORTS Australia.
