Goodwill Impairments Goodwill is tested for impairment at the reporting unit level. On November 1, 2017, the Company's former EG segment was realigned into two new reportable segments, Hybrid IT and Intelligent Edge. Further, following certain executive leadership changes in fiscal 2018, near the end of the fourth quarter, Hybrid IT segment management changed its evaluation of Hybrid IT to evaluate the previously integrated Communications and Media Services ("CMS") business separately from the remainder of Hybrid IT, resulting in a reassessment of the reporting units. As of October 31, 2018, the Company's reporting units within Hybrid IT include CMS and Hybrid IT excluding CMS. The Company expects to move CMS to the Corporate Investments segment under new management effective November 1, 2018. The Company's reporting units other than Hybrid IT are consistent with the reportable segments identified in Note 3, "Segment Information". Based on the results of the Company's annual impairment tests in fiscal 2018, 2017 and 2016, the Company determined that no impairment of goodwill existed. Based on the results of the Company's interim impairment tests in fiscal 2018 it was concluded that the fair value of CMS was less than its carrying amount. Prior to calculating the goodwill impairment loss, the Company analyzed the recoverability of CMS long-lived assets other than goodwill and concluded that those assets were not impaired. As a result, the Company recorded a goodwill impairment charge of $88 million. There is no remaining goodwill in the CMS reporting unit as of October 31, 2018. Intangible Assets Intangible assets comprise:
| As of October 31, 2018 |  | As of October 31, 2017

For fiscal 2018, the decrease in gross intangible assets was due primarily to $106 million of intangible assets which became fully amortized and were eliminated from gross intangible assets and accumulated amortization, partially offset by $41 million of purchases related to acquisitions. For fiscal 2017, the increase in gross intangible assets was due primarily to $688 million of purchases related to acquisitions, partially offset by $384 million of intangible assets which became fully amortized and were eliminated from gross intangible assets and accumulated amortization. The Company reclassified in-process research and development assets acquired of $57 million and $10 million to developed and core technology and patents as the projects were completed, and began amortization during fiscal 2018 and fiscal 2017, respectively. As of October 31, 2018, the weighted-average remaining useful lives of the Company's finite-lived intangible assets were as follows:
Finite-Lived Intangible Assets | Weighted-Average Remaining Useful Lives
| In years
Customer contracts, customer lists and distribution agreements | 4
Developed and core technology and patents | 4
Trade name and trade marks | 4
As of October 31, 2018, estimated future amortization expense related to finite-lived intangible assets was as follows:
Fiscal year | In millions
2019 | $ | 248 |
2020 | 197 |
2021 | 126 |
2022 | 92 |
2023 | 68 |
