Derivative Instruments, Hedging Activities and Fair Value Measurements [Abstract]

Hedging Instruments Under the FASB's Derivative and Hedging Guidance

The following table summarizes our portfolio of interest rate swaps at September 30, 2016:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Period of Hedge	Rate Swap	Accounting Treatment
Senior Notes OO	10 fixed-to-floating swaps	$	750.0	5/2015 to 5/2018	1.65% to 1.27%	Fair value hedge

As a result of lower market interest rates in June and July 2016, we entered into eight 30-year forward-starting swaps associated with anticipated future issuances of debt. At September 30, 2016, our portfolio of forward starting swaps was as follows:

Hedged Transaction	Number and Type of Derivatives Outstanding	Notional Amount		Expected Settlement Date	Average Rate Locked	Accounting Treatment
Future long-term debt offering	4 forward starting swaps	$	250.0	9/2017	1.91%	Cash flow hedge
Future long-term debt offering	4 forward starting swaps	$	275.0	5/2018	2.02%	Cash flow hedge

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.  The following table summarizes our portfolio of commodity derivative instruments outstanding at September 30, 2016 (volume measures as noted):

	Volume (1)		Accounting
Derivative Purpose	Current (2)	Long-Term (2)	Treatment
Derivatives designated as hedging instruments:
Natural gas processing:
Forecasted natural gas purchases for plant thermal reduction (Bcf)	24.4	3.3	Cash flow hedge
Forecasted sales of NGLs (MMBbls)	12.1	3.5	Cash flow hedge
Octane enhancement:
Forecasted purchase of NGLs (MMBbls)	1.3	n/a	Cash flow hedge
Forecasted sales of octane enhancement products (MMBbls)	1.4	n/a	Cash flow hedge
Natural gas marketing:
Forecasted purchases of natural gas for fuel (Bcf)	3.3	0.5	Cash flow hedge
Natural gas storage inventory management activities (Bcf)	8.2	n/a	Fair value hedge
NGL marketing:
Forecasted purchases of NGLs and related hydrocarbon products (MMBbls)	78.2	2.3	Cash flow hedge
Forecasted sales of NGLs and related hydrocarbon products (MMBbls)	99.0	7.0	Cash flow hedge
Refined products marketing:
Forecasted purchases of refined products (MMBbls)	0.3	n/a	Cash flow hedge
Forecasted sales of refined products (MMBbls)	0.4	n/a	Cash flow hedge
Refined products inventory management activities (MMBbls)	2.1	n/a	Fair value hedge
Crude oil marketing:
Forecasted purchases of crude oil (MMBbls)	7.4	n/a	Cash flow hedge
Forecasted sales of crude oil (MMBbls)	11.5	n/a	Cash flow hedge
Crude oil inventory management activities (MMBbls)	0.2	n/a	Fair value hedge
Derivatives not designated as hedging instruments:
Natural gas risk management activities (Bcf) (3,4)	98.2	20.9	Mark-to-market
NGL risk management activities (MMBbls) (4)	7.2	n/a	Mark-to-market
Crude oil risk management activities (MMBbls) (4)	28.5	0.9	Mark-to-market
(1)Volume for derivatives designated as hedging instruments reflects the total amount of volumes hedged whereas volume for derivatives not designated as hedging instruments reflects the absolute value of derivative notional volumes. (2)The maximum term for derivatives designated as cash flow hedges, derivatives designated as fair value hedges and derivatives not designated as hedging instruments is December 2017, June 2017 and March 2020, respectively. (3)Current and long-term volumes include 25.4 Bcf and 1.8 Bcf, respectively, of physical derivative instruments that are predominantly priced at a marked-based index plus a premium or minus a discount related to location differences. (4)Reflects the use of derivative instruments to manage risks associated with transportation, processing and storage assets.

Noncash Impairment Charges by Segment

Long-lived assets (including intangible assets with finite useful lives and property, plant and equipment) are reviewed for impairment (i.e., subject to nonrecurring fair value measurements) when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Long-lived assets with carrying values that are not expected to be recovered through future cash flows are written-down to their estimated fair values. The following table summarizes our non-cash impairment charges by segment during each of the periods indicated:

	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
	2016		2015		2016		2015
