[1] $184 million included in other non-operating expense and $21 million included in interest expense

[2] Included in other non-operating expense.

[3] 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.

[4] 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.

[5] 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.
