The Company amortizes intangible assets over their expected useful lives, which range between 1 and 15 years. During the six months ended September 30, 2017, $8.9 million of in-process research and development 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 2018 through fiscal 2022, absent any future acquisitions or impairment charges (amounts in thousands):

Amortization expense attributed to intangible assets was $122.7 million and $245.5 million for the three and six months ended September 30, 2017, respectively. Amortization expense attributed to intangible assets was $82.8 million and $165.3 million for the three and six months ended September 30, 2016, respectively. In the three and six months ended September 30, 2017, approximately $1.9 million and $3.9 million of amortization expense, respectively, was charged to cost of sales, and approximately $120.8 million and $241.6 million, respectively, was charged to operating expenses.  In the three and six months ended September 30, 2016, approximately $1.0 million and $1.9 million of amortization expense, respectively, was charged to cost of sales, and approximately $81.8 million and $163.4 million, respectively, was charged to operating expenses.  The Company recognized an immaterial amount of intangible asset impairment charges in the three and six months ended September 30, 2017. In connection with its acquisition of Atmel, the Company recognized intangible asset impairment charges of $2.0 million for the six months ended September 30, 2016. The impairment losses were recognized as a result of changes in the combined product roadmaps after the acquisition of Atmel that affected the use and life of these assets.

At March 31, 2017, 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 September 30, 2017, the Company has never recorded an impairment charge against its goodwill balance.
