The Company amortizes intangible assets over their expected useful lives, which range between 1 and 15 years. During the three months ended June 30, 2016, as a result of the Atmel transaction, the Company acquired $1,080.3 million of core and developed technology which has a weighted average amortization period of 11 years, $629.2 million of customer-related intangible assets which have a weighted average amortization period of 6 years, $28.7 million of intangible assets related to backlog with an amortization period of 1 year, $1.8 million of other intangible assets which have a weighted average amortization period of 5 years and $140.2 million of in-process technology which will begin amortization once the technology reaches technological feasibility. During the three months ended June 30, 2016, $8.9 million of in-process technology reached technological feasibility and was reclassified as core and developed technology and began being amortized over its estimated useful life. The following is an expected amortization schedule for the intangible assets for the remainder of fiscal 2017 through fiscal 2021, absent any future acquisitions or impairment charges (amounts in thousands):



Year ending March 31,	Projected Amortization Expense
2017	$253,615

Amortization expense attributed to intangible assets was $82.5 million and $35.7 million for the three months ended June 30, 2016 and June 30, 2015, respectively. In the three months ended June 30, 2016, approximately $0.9 million was charged to cost of sales, and approximately $81.6 million was charged to operating expenses. In the three months ended June 30, 2015, approximately $0.9 million was charged to cost of sales, and approximately $34.8 million was charged to operating expenses. The Company recognized impairment charges of $2.0 million in three months ended June 30, 2016. The Company recognized no impairment charges in the three months ended June 30, 2015.

Goodwill activity for the three months ended June 30, 2016 was as follows (amounts in thousands):



	Semiconductor Products Reporting Unit			Technology Licensing Reporting Unit
Balance at March 31, 2016	$	993,452		$	19,200

At March 31, 2016, the Company applied a qualitative goodwill impairment test to its two reporting units, concluding it was not more likely than not that goodwill was impaired. Through June 30, 2016, the Company has never recorded an impairment charge against its goodwill balance.
