Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments | Derivative Instruments The following describes our derivative classifications: Cash Flow Hedges. Includes certain derivative contracts we execute to mitigate the risk of price volatility in forecasted transactions. Fair Value Hedges. Includes derivative contracts we hold to hedge the risk of changes in the price of our inventory. Non-designated Derivatives. Includes derivatives we primarily transact to mitigate the risk of market price fluctuations in the form of swap or futures contracts as well as certain forward fixed price purchase and sale contracts, and for portfolio optimization. In addition, non-designated derivatives are held to hedge the risk of currency rate fluctuations.

Credit-Risk-Related Contingent Features We enter into derivative contracts which may require us to post collateral periodically. Certain of these derivative contracts contain credit-risk-related contingent clauses which are triggered by credit events. These credit events may include the requirement to post additional collateral or the immediate settlement of the derivative instruments upon the occurrence of a credit downgrade or if certain defined financial ratios fall below an established threshold. The following table presents the potential collateral requirements for derivative liabilities with credit-risk-contingent features (in millions):
