[1] As of September 1, 2016.

[2] Expected remaining term for amortization of the remaining unamortized discount and debt issuance costs as of September 1, 2016. Expected remaining term for capital lease obligations and other notes payable is the weighted-average remaining term.

[3] Weighted-average imputed rate of 3.3% and 3.7% as of September 1, 2016 and September 3, 2015, respectively.

[4] Weighted-average imputed rate of 3.4% and 4.5% as of September 1, 2016 and September 3, 2015, respectively.

[5] If we redeem prior to the applicable date with net cash proceeds of one or more equity offerings, the price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate principal amount of the respective notes being redeemed.

[6] 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.

[7] Based on our closing share price of $16.64 as of September 1, 2016.

[8] Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ended on June 30, 2016 did not exceed 130% of the conversion price per share, these notes were not convertible by the holders during the calendar quarter ended September 30, 2016. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2016; therefore, these notes are convertible by the holders through December 31, 2016. The 2033 Notes were classified as current as of 2015 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.

[9] The terms of our convertible notes give holders the right to require us to repurchase all or a portion of their notes at a date prior to the contractual maturities of the notes at a price equal to the principal amount thereof plus accrued interest.

[10] Holders have the right to convert all or a portion of their notes at a date prior to the contractual maturity if, during any calendar quarter, the closing price of our common stock for at least 20 trading days in the 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is more than 130% of the conversion price. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2016 for our 2032 Notes and 2033 Notes; therefore, those notes are convertible by the holders through December 31, 2016.

[11] Since the closing price of Micron's common stock for at least 20 trading days in the 30 trading day period ended on June 30, 2016 did not exceed 130% of the conversion price per share, these notes were not convertible by the holders during the calendar quarter ended September 30, 2016. The closing price of our common stock exceeded the thresholds for the calendar quarter ended September 30, 2016; therefore, these notes are convertible by the holders through December 31, 2016. The 2033 Notes were classified as current as of 2015 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.

[12] The 2043G Notes have an original principal amount of $820 million that accretes up to $917 million through the expected term in November 2028 and $1.03 billion at maturity in 2043. The discount is based on the principal at maturity.
