NOTE 10 - GOODWILL AND INTANGIBLE ASSETS

Goodwill, by segment, consists of the following:


(in millions)	HHI		PET		H&G		GAC		Total
As of September 30, 2016	$	702.8	$	299.8	$	196.5	$	934.2	$	2,133.3
PetMatrix acquisition		—		123.8		—		—		123.8
GloFish acquisition		—		11.2		—		—		11.2
Foreign currency impact		5.9		2.3		—		0.6		8.8
As of September 30, 2017	$	708.7	$	437.1	$	196.5	$	934.8	$	2,277.1
Foreign currency impact		(4.4)		(1.2)		—		(0.5)		(6.1)
Impairment		—		—		—		(92.5)		(92.5)
As of September 30, 2018	$	704.3	$	435.9	$	196.5	$	841.8	$	2,178.5

The fair values of the HHI, PET, and H&G reporting units exceeded their carrying values by 89%, 21%, and 222%, respectively, and did not recognize an impairment or deem the respective reporting units as ‘at risk’ of impairment. The Company recognized an impairment loss on goodwill of the GAC reporting unit of $92.5 million during the year ended September 30, 2018. The GAC goodwill impairment loss is a result of the annual impairment analysis identifying a reduction in the fair value less than the carrying value; primarily attributable to reduced operating results from operational changes driven by restructuring of the domestic manufacturing and distribution, increases in commodity costs, and increased market and pricing competition realized during the year.

The carrying value and accumulated amortization for intangible assets subject to amortization are as follows:



	2018						2017
(in millions)	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
Customer relationships	$	668.5	$	(259.1)	$	409.4	$	671.7	$	(222.3)	$	449.4
Technology assets		194.7		(77.6)		117.1		194.6		(59.7)		134.9
Tradenames		5.8		(3.3)		2.5		18.5		(15.1)		3.4
Total	$	869.0	$	(340.0)	$	529.0	$	884.8	$	(297.1)	$	587.7

Certain trade names intangible assets have an indefinite life and are not amortized. The balance of trade names not subject to amortization was $1,002.6 million and $1,024.3 million as of September 30, 2018 and 2017. During the year ended September 30, 2018, the Company recognized $20.3 million impairment on indefinite life intangible assets due to the reduction in value over certain tradenames associated with the PET segment driven by lost sales volumes attributable to safety recall and increased market competition. During the years ended September 30, 2017 and 2016, the Company recognized $16.3 million and $2.7 million, respectively, of impairment on indefinite life intangible assets that were primarily in response to changes in management’s strategy.

Amortization expense from intangible assets for the years ended September 30, 2018, 2017 and 2016 was $58.1 million, $62.0 million and $60.6 million, respectively. Excluding the impact of any future acquisitions or changes in foreign currency, the Company anticipates the annual amortization expense of intangible assets for the next five fiscal years will be as follows:


(in millions)	Amortization
2019	$	57.2
2020		57.1
2021		54.7
2022		49.4
2023		47.7
