There were no impairment charges related to purchased intangible assets for the first quarter of fiscal 2019 and fiscal 2018, respectively. Impairment charges are primarily a result of declines in estimated fair values of certain purchased intangible assets resulting from the reduction or elimination of expected future cash flows associated with certain of our technology and in-process research and development (IPR&D) intangible assets.

The following table presents the amortization of purchased intangible assets, including impairment charges (in millions):
