Hedging Activities and Fair Value Measurements [Abstract]

Hedging Activities and Fair Value Measurements

Note 13.  Hedging Activities and Fair Value Measurements

In the normal course of our business operations, we are exposed to certain risks, including changes in interest rates and commodity prices.  In order to manage risks associated with assets, liabilities and certain anticipated future transactions, we use derivative instruments such as futures, forward contracts, swaps, options and other instruments with similar characteristics.  Substantially all of our derivatives are used for non-trading activities.

Interest Rate Hedging Activities

We may utilize interest rate swaps, forward-starting swaps, options to enter into forward-starting swaps (“swaptions”), and similar derivative instruments to manage our exposure to changes in interest rates charged on borrowings under certain consolidated debt agreements.  This strategy may be used in controlling our overall cost of capital associated with such borrowings.

Forward-Starting Swaps

As a result of favorable market conditions, we terminated an aggregate $675.0 million notional amount of forward-starting swaps in March 2021, which resulted in a net cash payment of $0.1 million.  Since the original swaptions associated with these forward-starting swaps were not designated as hedging instruments and were subject to mark-to-market accounting, we previously incurred an unrealized, mark-to-market loss at inception of the forward starting swaps of $47.6 million that was reflected as an increase in interest expense in 2019.  Immediately following exercise of the swaptions and our being put into the forward-starting swaps, these instruments were designated as cash flow hedges.  For the period from inception through the termination date in March 2021, we recognized cumulative gains on the forward-starting swaps of $47.5 million in accumulated other comprehensive income, of which $45.9 million will be reclassified to earnings (as a decrease in interest expense) over the life of the associated debt obligations. We reclassified $1.6 million of the cumulative gain as a decrease in interest expense in March 2021.

We terminated an additional aggregate $400.0 million notional amount of forward-starting swaps in March 2021 due to favorable market conditions, which resulted in net cash proceeds of $75.3 million. As cash flow hedges, gains on these derivative instruments are reflected as a component of accumulated other comprehensive income and will be reclassified to earnings (as a decrease in interest expense) over the life of the associated future debt obligations.

As a result of these terminations, we do not have any interest rate derivative instruments outstanding at June 30, 2021.

Commodity Hedging Activities

The prices of natural gas, NGLs, crude oil, petrochemicals and refined products are subject to fluctuations in response to changes in supply and demand, market conditions and a variety of additional factors that are beyond our control.  In order to manage such price risks, we enter into commodity derivative instruments such as physical forward contracts, futures contracts, fixed-for-float swaps and basis swaps.

At June 30, 2021, our predominant commodity hedging strategies consisted of (i) hedging anticipated future purchases and sales of commodity products associated with transportation, storage and blending activities, (ii) hedging natural gas processing margins and (iii) hedging the fair value of commodity products held in inventory.  

The following table summarizes our portfolio of commodity derivative instruments outstanding at June 30, 2021 (volume measures as noted):

Derivative assets and liabilities recorded on our Unaudited Condensed Consolidated Balance Sheets are presented on a gross-basis and determined at the individual transaction level.  The tabular presentation above provides a means for comparing the gross amount of derivative assets and liabilities, excluding associated accounts payable and receivable, to the net amount that would likely be receivable or payable under a default scenario based on the existence of rights of offset in the respective derivative agreements.  Any cash collateral paid or received is reflected in these tables, but only to the extent that it represents variation margins.  Any amounts associated with derivative prepayments or initial margins that are not influenced by the derivative asset or liability amounts or those that are determined solely on their volumetric notional amounts are excluded from these tables.

The following tables present the effect of our derivative instruments designated as fair value hedges on our Unaudited Condensed Statements of Consolidated Operations for the periods indicated:

Derivatives in Fair Value Hedging Relationships	Location	Gain (Loss) Recognized in Income on Derivative
		For the Three Months Ended June 30,						For the Six Months Ended June 30,

Commodity derivatives	Revenue	$	38.8	$	126.7	$	208.5	$	117.3
Total		$	38.8	$	126.7	$	208.5	$	117.3

The gain (loss) corresponding to the hedge ineffectiveness on the fair value hedges was negligible for all periods presented. The remaining gain (loss) for each period presented is primarily attributable to prompt-to-forward month price differentials that were excluded from the assessment of hedge effectiveness.

The following tables present the effect of our derivative instruments designated as cash flow hedges on our Unaudited Condensed Statements of Consolidated Operations and Unaudited Condensed Statements of Consolidated Comprehensive Income for the periods indicated:

Derivatives in Cash Flow Hedging Relationships	Change in Value Recognized in Other Comprehensive Income (Loss) on Derivative
	For the Three Months Ended June 30,						For the Six Months Ended June 30,
	2021			2020			2021			2020
Interest rate derivatives	$	–		$	7.8		$	182.9		$	(270.3	)
Commodity derivatives – Revenue (1)		(290.5	)		(75.9	)		(732.7	)		401.9

Total	$	(290.4	)	$	(70.4	)	$	(568.7	)	$	126.6

(1) The fair value of these derivative instruments will be reclassified to their respective locations on the Unaudited Condensed Statement of Consolidated Operations when the forecasted transactions affect earnings.

Derivatives in Cash Flow Hedging Relationships	Location	Gain (Loss) Reclassified from Accumulated Other Comprehensive Income (Loss) to Income
		For the Three Months Ended June 30,						For the Six Months Ended June 30,
		2021			2020			2021			2020
Interest rate derivatives	Interest expense	$	(10.2	)	$	(9.7	)	$	(18.8	)	$	(19.3	)
Commodity derivatives	Revenue		99.3			209.8			(498.1	)		364.2
Commodity derivatives	Operating costs and expenses		0.1			(1.1	)		(18.6	)		0.1
Total		$	89.2		$	199.0		$	(535.5	)	$	345.0

Over the next twelve months, we expect to reclassify $39.8 million of losses attributable to interest rate derivative instruments from accumulated other comprehensive loss to earnings as an increase in interest expense.  Likewise, we expect to reclassify $284.4 million of losses attributable to commodity derivative instruments from accumulated other comprehensive loss to earnings, with $284.5 million as a decrease in revenue and $0.1 million as a decrease in operating costs and expenses.

The following table presents the effect of our derivative instruments not designated as hedging instruments on our Unaudited Condensed Statements of Consolidated Operations for the periods indicated:

Derivatives Not Designated as Hedging Instruments	Location	Gain (Loss) Recognized in Income on Derivative
		For the Three Months Ended June 30,					For the Six Months Ended June 30,
		2021			2020		2021		2020
Commodity derivatives	Revenue	$	79.5		$	45.7	$	36.4	$	98.7
Commodity derivatives	Operating costs and expenses		(0.9	)		0.9		–		0.8
Total		$	78.6		$	46.6	$	36.4	$	99.5

The $36.4 million gain recognized for the six months ended June 30, 2021 (as noted in the preceding table) from derivatives not designated as hedging instruments consists of $48.9 million of realized losses and $85.3 million of net unrealized mark-to-market gains attributable to commodity derivatives.

Fair Value Measurements

The following tables set forth, by level within the Level 1, 2 and 3 fair value hierarchy, the carrying values of our financial assets and liabilities at the dates indicated.  These assets and liabilities are measured on a recurring basis and are classified based on the lowest level of input used to estimate their fair value.  Our assessment of the relative significance of such inputs requires judgment.

The values for commodity derivatives are presented before and after the application of Chicago Mercantile Exchange (“CME”) Rule 814, which deems that financial instruments cleared by the CME are settled daily in connection with variation margin payments.  As a result of this exchange rule, CME-related derivatives are considered to have no fair value at the balance sheet date for financial reporting purposes; however, the derivatives remain outstanding and subject to future commodity price fluctuations until they are settled in accordance with their contractual terms.  Derivative transactions cleared on exchanges other than the CME (e.g., the Intercontinental Exchange or ICE) continue to be reported on a gross basis.

In the aggregate, the fair value of our commodity hedging portfolios at June 30, 2021 was a net derivative liability of $562.7 million prior to the impact of CME Rule 814.

Financial assets and liabilities recorded on the balance sheet at June 30, 2021 using significant unobservable inputs (Level 3) are not material to the Unaudited Condensed Consolidated Financial Statements.

Nonrecurring Fair Value Measurements

We did not have any significant nonrecurring fair value measurements during the six months ended June 30, 2021 or 2020.

See Note 4 for information regarding other non-cash asset impairment charges.

Other Fair Value Information

The carrying amounts of cash and cash equivalents (including restricted cash balances), accounts receivable, commercial paper notes and accounts payable approximate their fair values based on their short-term nature.  The estimated total fair value of our fixed-rate debt obligations was $33.19 billion and $35.0 billion at June 30, 2021 and December 31, 2020, respectively.  The aggregate carrying value of these debt obligations was $28.58 billion and $29.9 billion at June 30, 2021 and December 31, 2020, respectively.  These values are primarily based on quoted market prices for such debt or debt of similar terms and maturities (Level 2) and our credit standing.  Changes in market rates of interest affect the fair value of our fixed-rate debt.  The carrying values of our variable-rate long-term debt obligations approximate their fair values since the associated interest rates are market-based.  We do not have any long-term investments in debt or equity securities recorded at fair value.
