(1) Goodwill related to the MphasiS Limited reporting unit, which was sold in the fourth quarter of 2016.
(2) Goodwill is net of accumulated impairment losses of $13.7 billion, which were recorded prior to October 31, 2014. Of that amount, $8.0 billion relates to the Enterprise Services segment and the remaining $5.7 billion relates to the Software segment.
(3) Goodwill divested as part of the divestiture of the LiveVault and iManage businesses.
(4) In connection with the Separation, former Parent retained the marketing optimization software product group, a continuing business which had historically been managed by the Company and included in the Software segment. The adjustment reflects the impact of removing the related goodwill of $512 million, allocated on a relative fair value basis, from former Parent.
(5) Goodwill divested as part of the H3C transaction (EG), sale of TippingPoint (Software) and sale of MphasiS (ES).
(6) Primarily measurement period adjustments to provisional tax items recorded in conjunction with the Aruba acquisition.
Goodwill Impairments
Goodwill is tested for impairment at the reporting unit level. As of October 31, 2016, the Company's reporting units were consistent with the reportable segments identified in Note 2, "Segment Information". Based on the results of the Company's annual impairment tests for fiscal 2016, 2015 and 2014, the Company determined that no impairment of goodwill existed.

For fiscal 2016, the decrease in gross intangible assets was due primarily to $3.5 billion of intangible assets which became fully amortized and have been eliminated from gross intangible assets and accumulated amortization, and $478 million of intangible assets that have been divested ($379 million of accumulated amortization was associated with the divested assets). The decrease was partially offset by $11 million of purchases related to acquisitions. Intangible asset amortization expense for the fiscal year ended October 31, 2016 was $755 million.
 For fiscal 2015, the decrease in gross intangible assets was due primarily to $703 million of intangible assets that became fully amortized and have been eliminated from gross intangible assets and accumulated amortization, and the impact of removing intangible assets related to the marketing optimization software product group, which was retained by former Parent. The decrease was partially offset by intangible assets and in-process research and development resulting from the Company's acquisitions, primarily the acquisition of Aruba. Intangible asset amortization expense for the fiscal years ended October 31, 2015 and 2014 was $852 million and $906 million, respectively.
In-process research and development consists of efforts that are in process on the date the Company acquires a business. Under the accounting guidance for intangible assets, in-process research and development acquired in a business combination is considered an indefinite-lived intangible asset until completion or abandonment of the associated research and development efforts. The Company begins amortizing its in-process research and development intangible assets upon completion of the projects. If an in-process research and development project is abandoned, the Company records an expense for the value of the related intangible asset to its Consolidated and Combined Statement of Earnings in the period of abandonment. The Company reclassified in-process research and development assets acquired of $159 million to developed and core technology and patents as the projects were completed, and began amortization during fiscal 2016.
As of October 31, 2016, the weighted-average remaining useful lives of the Company's finite-lived intangible assets were as follows:
