We conducted our periodic assessment of long-lived assets in the fourth quarter of fiscal 2018 and identified the need for an intangible asset impairment charge in our Solar segment of $1.3 million due primarily to the decline in our expected performance of that segment. All remaining intangible assets are included in our Semiconductor segment.

Amortization expense related to intangible assets was $0.2 million, $0.8 million and $0.8 million in 2018, 2017 and 2016, respectively. The aggregate amortization expense for the intangible assets for each of the five succeeding fiscal years is estimated to be $0.3 million, $0.3 million, $0.1 million, $0.1 million, $0.1 million and $0.2 million in 2019, 2020, 2021, 2022, 2023 and thereafter, respectively.
