[1] | Weighted-average imputed rate of 3.7% and 4.3% as of September 3, 2015 and August 28, 2014, respectively.
[2] | Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 3, 2015. The expected remaining term of the 2031B Notes was not applicable because the notes were not outstanding as of September 3, 2015. Expected remaining term for capital lease obligations is the weighted-average remaining term.
[3] | Amount recorded for 2014 included the debt and equity components. The equity component was reclassified to a debt liability as a result of Micron's obligation to settle the conversions of the 2031B Notes in cash.
[4] | As holders had elected to convert these notes and we elected to settle the conversions in cash, the net carrying amount for 2014 included the debt component and equity component, which were reclassified to a debt liability as a result of our obligation to settle the conversions of the 2031B Notes in cash, resulting in an aggregate liability of $389 million. The outstanding principal reflects the original principal of the 2031B Notes.
[5] | Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on June 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 September 30, 2015. The closing price of our common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
[6] | 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.
[7] | The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term on November 15, 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity. See "2043G Notes" below.
[8] | Weighted-average imputed rate of 4.5% and 4.7% as of September 3, 2015 and August 28, 2014, respectively.
[9] | Micron has either the obligation or the option to pay cash for the principal amount due upon conversion for all of its convertible notes. Micron's current intent is to settle in cash the principal amount of all of its convertible notes upon conversion.
[10] | Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ending on June 30, 2015 exceeded 130% of the initial conversion price per share, holders have the right to convert their notes at any time during the calendar quarter ended September 30, 2015. The closing price of Micron's common stock also exceeded the thresholds for the calendar quarter ended September 30, 2015; therefore, these notes are convertible by the holders through December 31, 2015. The 2033 Notes are classified as current because the terms of these notes require us to pay cash for the principal amount of any converted notes.
