[1] Net carrying amount is the principal amount less unamortized debt discount and issuance costs. In addition, the net carrying amount as of August 30, 2018 and August 31, 2017 included $132 million and $31 million, respectively, of derivative debt liabilities recognized as a result of our election to settle entirely in cash converted notes with an aggregate principal amount of $35 million and $16 million, respectively.

[2] Based on the trading price of our common stock of $52.76 as of August 30, 2018.

[3] It is our current intent to settle in cash the principal amount of our convertible notes upon conversion. As a result, only the amounts payable in excess of the principal amounts upon conversion of our convertible notes are considered in diluted earnings per share under the treasury stock method. For each of our convertible notes, we may elect to settle any amounts in excess of the principal in cash, shares of our common stock, or a combination thereof.

[4] 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 June 30, 2018, these notes are convertible by the holders through the calendar quarter ended September 30, 2018. Additionally, the closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2018; therefore, these notes are convertible by the holders at any time through December 31, 2018.

[5] Represents 130% of the conversion price per share. If the trading price of our common stock exceeds such threshold for a specified period, holders may convert such notes during a specified period. See "Conversion Rights" below.

[6] Current debt as of August 30, 2018 included an aggregate of $165 million for the settlement obligation (including principal and amounts in excess of principal) for conversions of our 2033F Notes that will settle in cash in the first quarter of 2019. The remainder of the 2033F Notes were classified as current as of August 30, 2018 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 that date.

[7] The 2043G Notes outstanding as of August 30, 2018 have an original principal amount of $815 million that accretes up to $911 million through the expected term in November 2028 and $1.02 billion at maturity in 2043.
