Equity Earnings

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

	For the Year Ended December 31,
	2018			2017			2016
NGL Pipelines & Services	$	117.0		$	73.4		$	61.4
Crude Oil Pipelines & Services		365.4			358.4			311.9
Natural Gas Pipelines & Services		6.8			3.8			3.8
Petrochemical & Refined Products Services (1)		(9.2	)		(9.6	)		(15.1	)
Total	$	480.0		$	426.0		$	362.0

(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 market and income approaches, indicate that the fair value of this investment remains 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,
	2018		2017
NGL Pipelines & Services	$	21.7	$	22.9
Crude Oil Pipelines & Services		17.4		18.2
Petrochemical & Refined Products Services		1.7		1.8
Total	$	40.8	$	42.9

In total, amortization of excess cost amounts were $2.1 million for each of the years ended December 31, 2018, 2017 and 2016. We forecast that our amortization of excess cost amount will approximate $2.1 million in each of the next five years.
