Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives  

We enter into financial derivative contracts in order to mitigate the risk of market price fluctuations in aviation, land and marine fuel, to offer our customers fuel pricing alternatives to meet their needs and to mitigate the risk of fluctuations in foreign currency exchange rates. If the derivative instrument is not designated in a hedge relationship, changes in the estimated fair market value are recognized as a component of revenue, cost of revenue or other income (expense), in the consolidated statements of income and comprehensive income.

Derivatives which qualify for hedge accounting may be designated as either a fair value or cash flow hedge. For our fair value hedges, changes in the estimated fair market value of the hedging instrument and the hedged item are recognized in the same line item as the underlying transaction type in the consolidated statements of income and comprehensive income. The gains or losses on derivative instruments designated as cash flow hedges of forecasted transactions are initially reported as a component of accumulated other comprehensive income and subsequently reclassified into earnings once the future transactions affects earnings.

Cash flows for our hedging instruments are classified in the same category as the underlying hedged items. If for any reason hedge accounting is discontinued, then any cash flows subsequent to the date of discontinuance will be classified in a manner consistent with the nature of the instrument.

The following describes our derivative classifications:

Cash Flow Hedges. Includes certain derivative contracts we execute to mitigate the risk of price or foreign currency 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 swaps 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 instrument contracts which may require us to periodically provide collateral. Certain derivative contracts contain credit-risk-related contingent clauses which are triggered by credit events. These credit events may include the requirement to provide 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):

Net derivatives liability positions with credit contingent features	$	10.8	$	11.8
Maximum potential collateral requirements	$	10.8	$	11.8

At March 31, 2018 and December 31, 2017, there was no collateral held by our counterparties on these derivative contracts with credit-risk-contingent features.
