[1] Net carrying amount is the principal amount less unamortized debt discount and issuance costs. In addition, the net carrying amount for our 2033E Notes for 2017 included $31 million of derivative debt liabilities recognized as a result of our election to settle entirely in cash converted notes with an aggregate principal amount of $16 million.
[2] If we redeem prior to the applicable date with net cash proceeds of one or more equity offerings, the redemption price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate original principal amount of the respective series of notes being redeemed. The 2025 Notes and 2026 Notes can not be redeemed with cash proceeds from an equity offering because the principal amount outstanding as of August 31, 2017 of such notes is less than 65% of the original principal amount issued.
[3] In the first quarter of 2018, we issued a notice to redeem our 2023 Notes. See "Debt Repurchases and Conversions" below.
[4] Based on the trading price of our common stock of $31.97 as of August 31, 2017.
[5] 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.
[6] 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, 2017, these notes are convertible by the holders through the calendar quarter ended September 30, 2017. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2017; therefore, these notes are convertible by the holders through December 31, 2017. The 2033 Notes were classified as current as of August 31, 2017 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] Since the closing price of Micron's 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, 2017, these notes are convertible by the holders through the calendar quarter ended September 30, 2017. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2017; therefore, these notes are convertible by the holders through December 31, 2017. The 2033 Notes were classified as current as of August 31, 2017 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.
[8] Represents 130% of the conversion price per share. If the trading price of our common stock price exceeds such threshold for a specified period, holders may convert such notes. See "Conversion Rights" below.
[9] The net carrying amount for 2017 included $31 million of derivative debt liabilities recognized as a result of our election to settle entirely in cash converted notes with an aggregate principal amount of $16 million. See "Convertible Senior Notes" below.
