Cash Conversion Option, Note Hedge and Contingent Interest features related to the 3.25% Cash Convertible Senior Notes

The cash conversion option is a derivative instrument which is recorded at fair value quarterly with any change in fair value being recognized in our consolidated statements of income as non-cash convertible debt related expense. The note hedge is accounted for as a derivative instrument and, as such, is recorded at fair value quarterly with any change in fair value being recognized in our consolidated statements of income as non-cash convertible debt related expense.

We expect the gain or loss associated with changes to the valuation of the note hedge to substantially offset the gain or loss associated with changes to the valuation of the cash conversion option. However, they will not be completely offsetting as a result of changes in the credit valuation adjustment related to the note hedge. Our most significant credit exposure arises from the note hedge. The fair value of the note hedge reflects the maximum loss that would be incurred should the option counterparties fail to perform according to the terms of the note hedge agreement. See Note 11. Consolidated Debt for specific details related to the Cash Conversion Option, Note Hedge and contingent interest features of the 3.25% Notes.

Energy Price Risk

Following the expiration of certain long-term energy sales contracts, we may have exposure to market risk, and therefore revenue fluctuations, in energy markets. We have entered into contractual arrangements that will mitigate our exposure to this volatility through a variety of hedging techniques, and will continue to do so in the future. Our efforts in this regard will involve only mitigation of price volatility for the energy we produce, and will not involve speculative energy trading. Consequently, we have entered into agreements with various financial institutions to hedge our exposure to market risk. As of December 31, 2012, the fair value of the energy derivatives of $1 million, pre-tax, was recorded as a current liability and as a component of AOCI.
