Future amortization expense related to the net carrying amount of intangible assets as of October 28, 2018 is estimated to be $6 million for the remainder of fiscal year 2019, $21 million in fiscal year 2020, $12 million in fiscal year 2021, $5 million in fiscal year 2022, $4 million in fiscal year 2023, and $1 million in fiscal year 2024.
