Paragraphs:
Amortization of Intangible Assets: Substantially all of our intangible assets were acquired through our business combinations. We amortize our intangible assets over, and monitor the appropriateness of, the estimated useful lives of these assets. We also periodically review these intangible assets for potential impairment based upon relevant facts and circumstances. Note 6 of Notes to Consolidated Financial Statements included elsewhere in this Annual report has additional information regarding our intangible assets and related amortization.
Amortization of intangible assets increased in fiscal 2019 compared to fiscal 2018 primarily due to additional amortization from intangible assets, which primarily included developed technology that we acquired in connection with our recent acquisitions, partially offset by a reduction in expenses associated with certain of our intangible assets that became fully amortized.
Question:
Why did amortization of intangible assets increase in fiscal 2019 relative to fiscal 2018?
