Goodwill and Intangible Assets, Net

During the first quarter of fiscal 2019, the Company revised the composition of its reportable segments as a result of certain organizational changes (Refer to Note 18 for details). Goodwill was reallocated between the two reportable segments using a relative fair value approach. As a result, the Company completed assessments of any potential goodwill impairment for all reportable segments immediately prior to and after the reallocation and determined that no impairment existed.

Goodwill balances by reportable segment as of July 1, 2018 and April 1, 2018 are as follows:



	Reportable Segments
(in thousands)	Communications			Computing, Consumer and Industrial		Total
Balance as of April 1, 2018	$	141,300		$	278,817	$	420,117

Balance as of July 1, 2018	$	120,094		$	300,023	$	420,117

Goodwill balances as of July 1, 2018 and April 1, 2018 were net of $920.3 million in accumulated impairment losses.

Intangible asset balances as of July 1, 2018 and April 1, 2018 are summarized as follows:

Amortization expense for the three months ended July 1, 2018 and July 2, 2017 was $10.1 million and $11.7 million, respectively.

As a result of the acquisition of GigPeak, the Company recognized additional intangible assets with fair value of $97.9 million during the three months ended July 2, 2017 (see Note 4). In the first quarter of fiscal 2018, the Company recorded an accelerated amortization charge of $2.0 million related to certain software licenses as the estimated future cash flows expected resulting from the use of the assets were less than the carrying amount.

The intangible assets are being amortized over estimated useful lives of 1 to 7 years.

Based on the intangible assets recorded as of July 1, 2018, the expected future amortization expense for intangible assets is as follows (in thousands):



Fiscal Year	Amount
2019 (Remaining 9 months)	$	30,530
2020	40,573
2021	39,617
