Derivative Instruments Derivative Instruments
The following describes our derivative classifications:
Fair Value Hedges. Includes derivative contracts we hold to hedge the risk of changes in the price of our inventory.

Cash Flow Hedges. Includes derivative contracts we execute to mitigate the risk of price and interest rate volatility in forecasted transactions.

Non-designated Derivatives. Includes derivatives we primarily transact to mitigate the risk of market price fluctuations in swaps or futures contracts, as well as certain forward fixed price purchase and sale contracts to hedge the risk of currency rate fluctuations and for portfolio optimization.
In March 2020, we entered into a $300 million, one-month LIBOR, floating-for-fixed non-amortizing interest rate swap contract ("IR Swap") with a maturity date in March 2025. The IR Swap was designated as a cash flow hedge to mitigate potential adverse changes in interest rates related to certain variable rate debt obligations. Changes in the IR Swap's fair value recorded periodically in Accumulated other comprehensive income, are subsequently reclassified to our Consolidated Statements of Income and Comprehensive Income within Interest expense and other financing costs, net when the underlying hedged variable rate interest payments are accrued.

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):
