GNU incurred an impairment loss of $4.5 million during the fourth quarter of fiscal 2015. GNU did not incur an impairment loss in fiscal 2017 or fiscal 2016. CRA did not incur an impairment loss during fiscal 2017, fiscal 2016 or fiscal 2015 as there were no events or circumstances that would more likely than not reduce CRA's fair value below its carrying amount, and CRA's estimated fair value was greater than its carrying value as of October 15th of each of these fiscal years.

Intangible assets that are separable from goodwill and have determinable useful lives are valued separately and amortized over their expected useful lives. There were impairment losses of $0.5 million related to intangible assets during fiscal 2017. There were no impairment losses related to intangible assets during fiscal 2016 or fiscal 2015.

The components of acquired identifiable intangible assets are as follows (in thousands):

	December 30, 2017		December 31, 2016
Non-competition agreements, net of accumulated amortization of $464 and $3,821, respectively	$	260	$	80
Customer relationships, net of accumulated amortization of $3,172 and $5,181, respectively		8,948		2,605

Total, net of accumulated amortization of $3,636 and $9,002, respectively	$	9,208	$	2,685

Amortization of intangible assets was $1.5 million, $0.9 million, and $1.0 million in fiscal 2017, fiscal 2016, and fiscal 2015, respectively. Amortization of intangible assets held at December 30, 2017 for the next five fiscal years and thereafter is expected to be as follows (in thousands):

Fiscal Year	Amortization Expense
2018	$	1,383
2019		1,365
2020		1,388
2021		921
2022		823
