[1] (1) We have the obligation or option to pay cash for the aggregate 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.
[2] (3) As a result of these notes being convertible at the option of the holder through March 31, 2014, and because the terms of these notes would require us to pay cash for the principal amount of any converted notes, amounts are classified as current.
[3] (2) Since the closing price of our common stock for at least 20 trading days in the 30 trading day period ending on December 31, 2013 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 March 31, 2014.
[4] (3) The original principal amount of $820 million accretes up to $917 million in November 2028 and $1,025 million at maturity in 2043.
[5] (1) Holders have the right to convert all or a portion of their notes at a date or dates earlier than 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 initial conversion price.
[6] (2) Based on our closing share price of $24.19 as of February 27, 2014.
