[1] | Weighted-average imputed rate of 3.8% and 3.7% as of December 3, 2015 and September 3, 2015, respectively.
[2] | Based on our closing share price of $15.61 as of December 3, 2015.
[3] | Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on September 30, 2015 exceeded 130% of the conversion price per share, holders had the right to convert their notes at any time during the calendar quarter ended December 31, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended December 31, 2015; therefore, these notes are convertible by the holders through March 31, 2016. The 2033 Notes are classified as current because the terms of these notes also require us to pay cash for the principal amount of any converted notes.
[4] | We have either the obligation or the option to pay cash for the principal amount due upon conversion for all of our convertible notes. Since it is our current intent to settle in cash the principal amount of all of our convertible notes upon conversion, the dilutive effect of such notes on earnings per share is computed under the treasury stock method.
[5] | The terms of our convertible notes give holders the right to require us to repurchase all or a portion of their notes at a date prior to the contractual maturity at a price equal to the principal amount thereof plus accrued interest.
[6] | Holders have the right to convert all or a portion of their notes at a date prior to the contractual maturity if, during any calendar quarter, the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2015 for our 2032 Notes and 2033 Notes; therefore, those notes were convertible by the holders through December 31, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended December 31, 2015; therefore, these notes are convertible by the holders through March 31, 2016.
[7] | The original principal amount of $820 million accretes up to $917 million in November 2028 and $1.03 billion at maturity in 2043.
