Schedule of Net Benefit Costs [Table Text Block]

The following tables set forth the components of net periodic benefit cost of the Company’s postretirement benefit plan for the periods presented:

	Successor									Predecessor
	Year Ended December 31, 2014			Year Ended December 31, 2013			Period from Acquisition (March 26, 2012) to December 31, 2012			Period from January 1, 2012 to March 25, 2012
Service cost	$	—		$	—		$	—		$	1
Interest cost	1			1			1			1
Expected return on plan assets	(5		)	(5		)	(4		)	(1		)
Prior service credit amortization	1			1			—			(1		)

⁽¹⁾  Subsequent to the ETE Merger, the Company amended certain of its other postretirement employee benefit plans to prospectively restrict participation in the plans for certain active employees.  The plan amendments resulted in the plans becoming currently over-funded and, accordingly, the Company recorded a gross pre-tax curtailment gain of $75 million, $60 million of which is subject to refund to customers; thus, the net curtailment gain recognition was $15 million.

Schedule of Assumptions Used [Table Text Block]

The weighted-average assumptions used in determining net periodic benefit cost for the periods presented are shown in the table below:

	Successor						Predecessor
	Year Ended December 31, 2014		Year Ended December 31, 2013		Period from Acquisition (March 26, 2012) to December 31, 2012		Period from January 1, 2012 to March 25, 2012

Taxable accounts	4.50	%	4.50	%	4.50	%	4.50	%

Schedule of Health Care Cost Trend Rates [Table Text Block]

The assumed health care cost trend rates used to measure the expected cost of benefits covered by the plans are shown in the table below:

	December 31,
	2014		2013
Health care cost trend rate	7.60	%	8.06	%
Rate to which the cost trend is assumed to decline (the ultimate trend rate)	4.90	%	4.91	%
Year that the rate reaches the ultimate trend rate	2021		2021

Schedule of Effect of One-Percentage-Point Change in Assumed Health Care Cost Trend Rates [Table Text Block]

Assumed health care cost trend rates have a significant effect on the amounts reported for health care plans.  A one-percentage-point change in assumed health care cost trend rates would have the following effects:

	One Percentage Point Increase		One Percentage Point Decrease
Effect on accumulated postretirement benefit obligation	$	1	$	(1	)
