The results of the Company's goodwill impairment test performed in the fourth quarter of fiscal 2019 and 2018 indicated that the estimated fair value of all reporting units exceeded their respective carrying values. There were no reporting units at risk of impairment as of the fiscal 2019 and 2018 annual test dates. During fiscal 2017, the Company recorded goodwill impairment charges of $57.0 million. During fiscal 2019, management reorganized its operating segments such that certain immaterial components of the EMEA operating segment became components of the All Other operating segment. As a result, the Company transferred $1.1 million of goodwill to the All Other operating segment, which represented the portion of goodwill associated with these components.

The gross carrying amount of intangible assets and the related accumulated amortization as of March 30, 2019 and March 31, 2018 is as follows:

Intangible assets include the value assigned to license rights and other developed technology, patents, customer contracts and relationships and trade names. The estimated useful lives for all of these intangible assets are 5 to 18 years. The changes to the net carrying value of the Company's intangible assets from March 31, 2018 to March 30, 2019 reflect the impact of amortization expense, partially offset by the investment in capitalized software.

Aggregate amortization expense for amortized intangible assets for fiscal 2019, 2018, and 2017 was $32.6 million, $31.9 million and $37.2 million, respectively. During fiscal 2017, the Company impaired $4.8 million of intangible assets. Amortization expense for fiscal 2017 included $4.0 million of amortization expense resulting from these intangible asset impairments. There were no intangible asset impairments during fiscal 2019 and 2018.

Future annual amortization expense on intangible assets is estimated to be as follows:



(In thousands)
Fiscal 2020	$	28,226
Fiscal 2021	$	26,593
Fiscal 2022	$	12,013
Fiscal 2023	$	9,375
