Our derivative financial instruments do not qualify for hedge treatment; therefore the change in fair value of these instruments is recognized immediately in our consolidated statements of operations, and reported in other income, net. Gains and losses from our derivative financial instruments are presented individually in the accompanying consolidated statements of cash flows, “Supplemental cash flow information.”

1.125% Notes Call Spread Overlay. Concurrent with the issuance of the 1.125% Convertible Notes in 2013, we entered into privately negotiated hedge transactions (collectively, the 1.125% Call Option) and warrant transactions (collectively, the 1.125% Warrants), with certain of the initial purchasers of the 1.125% Convertible Notes (the Counterparties). We refer to these transactions collectively as the Call Spread Overlay. Under the Call Spread Overlay, the cost of the 1.125% Call Option we purchased to cover the cash outlay upon conversion of the 1.125% Convertible Notes was reduced by proceeds from the sale of the 1.125% Warrants. Assuming full performance by the Counterparties (and 1.125% Warrants strike prices in excess of the conversion price of the 1.125% Convertible Notes), these transactions are intended to offset cash payments in excess of the principal amount of the 1.125% Convertible Notes due upon any conversion of such notes.

1.125% Call Option. The 1.125% Call Option, which is indexed to our common stock, is a derivative asset that requires mark-to-market accounting treatment due to cash settlement features until the 1.125% Call Option settles or expires. For further discussion of the inputs used to determine the fair value of the 1.125% Call Option, refer to Note 4, “Fair Value Measurements.”

1.125% Conversion Option. The embedded cash conversion option within the 1.125% Convertible Notes is accounted for separately as a derivative liability, with changes in fair value reported in our consolidated statements of operations until the cash conversion option settles or expires. For further discussion of the inputs used to determine the fair value of the 1.125% Conversion Option, refer to Note 4, “Fair Value Measurements.”

As of December 31, 2017, the 1.125% Call Option and the 1.125% Conversion Option were classified as a current asset and current liability, respectively, because the 1.125% Convertible Notes may be converted within twelve months of December 31, 2017, as described in Note 11, “Debt.”
