Income Taxes [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the nine months ended September 30, 2013 and 2012 was 33.8%. In connection with the conversion of our 2033 Notes and 2038 Notes, we reclassified $52.7 million, representing the excess of the accreted value of the notes for income tax purposes over the conversion value, from long-term deferred tax liability to current taxes payable. In addition, we reclassified $34.5 million, representing the difference between the issue price of the notes and the conversion value, from long-term deferred tax liability to additional paid-in capital. In third quarter of 2013, we paid approximately $40 million of the tax liability resulting from the conversion of the notes and we expect to pay the remaining liability in the fourth quarter of 2013. At September 30, 2013, our unrecognized tax benefits were $141.5 million. Of this amount, approximately $62.8 million would affect our effective tax rate upon resolution of the uncertain tax positions.
