[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 March 31, 2018, these notes are convertible by the holders at any time through the calendar quarter ended June 30, 2018. Current debt as of May 31, 2018 included an aggregate of $553 million for the settlement obligation (including principal and amounts in excess of principal) for conversions of certain convertible notes that will settle in cash in the fourth quarter of 2018. Additionally, the closing price of our common stock also exceeded the thresholds for the calendar quarter ended June 30, 2018; therefore, these notes are convertible by the holders at any time through September 30, 2018.

[2] The 2032C Notes were classified as current as of May 31, 2018 because the holders can require us to repurchase for cash all or a portion of the 2032C Notes on May 1, 2019.
