During the second quarter of fiscal 2019, the Company recorded $180.0 million of goodwill and $81.5 million of intangibles attributable to the acquisition of Deephi Technology Co., Ltd (Deephi Tech). See "Note 19. Business Combination" to our condensed consolidated financial statements.

Based on the carrying value of acquisition-related intangibles recorded as of September 29, 2018, assuming no subsequent acquisition or impairment of the underlying assets, and the expected timing of completion of in-process research and development, the annual amortization expense for acquisition-related intangibles is expected to be as follows:



Fiscal	(In thousands)
2019 (remaining six months)	$	3,732
2020	13,613
2021	17,983
2022	16,631
