Goodwill	$	620,852		$	340,718

Based on the carrying value of acquisition-related intangibles recorded as of September 28, 2019, and assuming no subsequent acquisition or impairment of the underlying assets, the annual amortization expense for acquisition-related intangibles is expected to be as follows:



Fiscal	(In thousands)
2020 (remaining six months)	$	18,359
2021	36,696
2022	34,217
2023	32,207
2024	27,860
Thereafter	5,811
Total	$	155,150

In-process research and development is not subject to amortization prior to the completion of the projects and therefore the balance is excluded from the above annual amortization expense schedule.
