[1] | Since the closing price of our common stock exceeded 130% of the conversion price per share for at least 20 trading days in the 30 trading day period ended on September 30, 2017, these notes are convertible by the holders through the calendar quarter ended December 31, 2017. The 2033 Notes were classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes and holders of these notes had the right to convert their notes as of the dates presented. A portion of the 2032C Notes were classified as current because holders had converted the notes and they were not settled as of November 30, 2017.
