Mixed NGLs from the Rocky Mountains, Permian Basin and Mid-Continent regions are delivered to the Texas Express Pipeline via an interconnect with our Mid-America Pipeline System near Skellytown. The pipeline also transports mixed NGLs from two gathering systems owned by TEG to Mont Belvieu. In addition, mixed NGLs from the Denver-Julesburg Basin in Colorado are transported to the Texas Express Pipeline using the Front Range Pipeline.



TEG owns two NGL gathering systems that deliver volumes to the Texas Express Pipeline. These gathering systems commenced operations in November 2013. The Elk City gathering system gathers mixed NGLs from natural gas processing plants in the Anadarko/Granite Wash production area located in the Texas Panhandle and western Oklahoma. The North Texas gathering system gathers mixed NGLs from natural gas processing plants in the Barnett Shale production area in North Texas. An affiliate of Enbridge Energy Partners, L.P. serves as operator of these two NGL gathering systems.

The Longhaul System provides north-to-south transportation of crude oil from the Cushing hub to Seaway's Jones Creek terminal near Freeport, Texas and our terminal located near Katy, Texas. In July 2014 we completed a pipeline looping project involving our Longhaul System. This expansion project entailed the construction of an additional pipeline that transports crude oil southbound from the Cushing hub to Seaway's Jones Creek terminal.

The Freeport System consists of a marine dock, three pipelines and other related facilities that transport crude oil to and from Freeport to the Jones Creek terminal. The Texas City System consists of a ship unloading dock, storage tanks, various pipelines and other related facilities that deliver crude oil from Texas City, Texas to Galena Park, Texas and other nearby locations.

Offshore Pipelines & Services

Equity Earnings

The following table presents our equity in income (loss) of unconsolidated affiliates by business segment for the periods indicated:

	For the Year Ended December 31,
	2015			2014			2013
NGL Pipelines & Services	$	57.5		$	30.6		$	15.7
Crude Oil Pipelines & Services		281.4			184.6			140.3
Natural Gas Pipelines & Services		3.8			3.6			3.8
Petrochemical & Refined Products Services (1)		(15.7	)		(13.3	)		(22.3	)
Offshore Pipelines & Services		46.6			54.0			29.8
Total	$	373.6		$	259.5		$	167.3

(1) Losses are primarily attributable to our investment in Centennial. As a result of a trend in declining earnings, we estimated the fair value of this equity-method investment during each of the last three fiscal years. Our estimates, based on a combination of the market and income approaches, indicate that the fair value of this investment remains substantially in excess of its carrying value.

Excess Cost

On occasion, the price we pay to acquire an ownership interest in a company exceeds the underlying carrying value of the capital accounts we acquire. These excess cost amounts are attributable to the fair value of the underlying tangible assets of these entities exceeding their respective book carrying values at the time of our acquisition of ownership interests in these entities. We amortize such excess cost amounts as a reduction to equity earnings in a manner similar to depreciation.

The following table presents our unamortized excess cost amounts by business segment at the dates indicated:

	December 31,
	2015		2014
NGL Pipelines & Services	$	25.3	$	26.5
Crude Oil Pipelines & Services		19.3		21.7
Petrochemical & Refined Products Services		2.3		2.4
Offshore Pipelines & Services (1)		--		9.0
Total	$	46.9	$	59.6

(1) Our investments in unconsolidated affiliates classified within the Offshore Pipelines & Services segment were sold to Genesis in July 2015.

In total, amortization of excess cost amounts were $4.9 million, $3.3 million and $3.3 million for the years ended December 31, 2015, 2014 and 2013, respectively. We forecast that our amortization of excess cost amount will approximate $2.2 million in each of the next five years.
