The goodwill acquired pertains to the fiscal 2018 acquisitions described in Note 2, Acquisitions, and represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities and noncontrolling interests assumed. The Company estimates that nearly all of the goodwill acquired in fiscal 2018 will be deductible for income tax purposes. The adjustments to goodwill represent immaterial measurement period adjustments to the purchase price allocation of certain fiscal 2017 acquisitions. Foreign currency translation adjustments are included in other comprehensive income (loss) in the Company's Condensed Consolidated Statements of Comprehensive Income.

The increase in the gross carrying amount of customer relationships, intellectual property and non-amortizing trade names as of July 31, 2018 compared to October 31, 2017 principally relates to such intangible assets recognized in connection with the fiscal 2018 acquisitions (see Note 2, Acquisitions). The weighted-average amortization period of the customer relationships and intellectual property acquired during fiscal 2018 is 7 and 10 years, respectively.
Amortization expense related to intangible assets for the nine months ended July 31, 2018 and 2017 was $37.5 million and $28.2 million, respectively. Amortization expense related to intangible assets for the three months ended July 31, 2018 and 2017 was $12.7 million and $9.9 million, respectively. Amortization expense related to intangible assets for the remainder of fiscal 2018 is estimated to be $12.5 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $48.7 million in fiscal 2019, $45.8 million in fiscal 2020, $43.0 million in fiscal 2021, $36.7 million in fiscal 2022, $31.7 million in fiscal 2023, and $163.5 million thereafter.
