Income Taxes [Abstract]
Income Taxes	Income Taxes On September 15, 2015, we filed our election to be taxed as a REIT for U.S. federal income tax purposes for the period July 17, 2014, through December 31, 2014, and all future calendar years. As of July 17, 2014, we were organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) and, accordingly, we have not provided for U.S. federal income tax on our REIT taxable income that we distributed to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities, and our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, we have provided for their federal, state and foreign income taxes. As a result of our REIT conversion, our effective tax rate subsequent to the Separation was substantially lower than previous periods. Prior to the Separation, our income tax provisions were calculated on a separate tax return basis, with us as the taxpayer, even though our U.S. operating results were included in the consolidated federal, and certain state and local income tax returns of CBS. We believe that the assumptions and estimates used to determine these tax amounts were reasonable. However, the 2014 consolidated financial statements may not necessarily reflect our income tax expense or tax payments, or what our tax amounts would have been if we had been a stand-alone company operating as a REIT during the period prior to the Separation. Our effective income tax rate represents a combined annual effective tax rate for federal, state, local and foreign taxes applied to interim operating results. In the three and nine months ended September 30, 2015, our effective tax rate differed from the U.S. federal statutory income tax rate primarily due to our REIT status, including the dividends paid deduction, the impact of state and local taxes, and the effect of foreign operations. Our effective income tax rate in the three and nine months ended September 30, 2014, differed from the U.S. federal statutory income tax rate primarily due to a non-cash benefit of $232.3 million recorded as a result of our REIT conversion in 2014, partially offset by the impact of state and local taxes, and the effect of foreign operations.

Income Taxes

On September 15, 2015, we filed our election to be taxed as a REIT for U.S. federal income tax purposes for the period July 17, 2014, through December 31, 2014, and all future calendar years. As of July 17, 2014, we were organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”) and, accordingly, we have not provided for U.S. federal income tax on our REIT taxable income that we distributed to our stockholders. We have elected to treat our subsidiaries that participate in certain non-REIT qualifying activities, and our foreign subsidiaries, as taxable REIT subsidiaries (“TRSs”). As such, we have provided for their federal, state and foreign income taxes.

As a result of our REIT conversion, our effective tax rate subsequent to the Separation was substantially lower than previous periods. Prior to the Separation, our income tax provisions were calculated on a separate tax return basis, with us as the taxpayer, even though our U.S. operating results were included in the consolidated federal, and certain state and local income tax returns of CBS. We believe that the assumptions and estimates used to determine these tax amounts were reasonable. However, the 2014 consolidated financial statements may not necessarily reflect our income tax expense or tax payments, or what our tax amounts would have been if we had been a stand-alone company operating as a REIT during the period prior to the Separation.

Our effective income tax rate represents a combined annual effective tax rate for federal, state, local and foreign taxes applied to interim operating results.

In the three and nine months ended September 30, 2015, our effective tax rate differed from the U.S. federal statutory income tax rate primarily due to our REIT status, including the dividends paid deduction, the impact of state and local taxes, and the effect of foreign operations. Our effective income tax rate in the three and nine months ended September 30, 2014, differed from the U.S. federal statutory income tax rate primarily due to a non-cash benefit of $232.3 million recorded as a result of our REIT conversion in 2014, partially offset by the impact of state and local taxes, and the effect of foreign operations.
