During the three months ended January 31, 2021, there were no additions to goodwill or to other intangible assets. During the three months ended January 31, 2021, other intangible assets in total increased $1 million due to the impact of foreign currency translation.

In general, for United States federal tax purposes, goodwill from asset purchases is deductible; however, any goodwill created as part of a stock acquisition is not deductible. 

Each quarter we review the events and circumstances to determine if impairment of indefinite-lived intangible assets and goodwill is indicated. During the three months ended January 31, 2021 and 2020 we did not identify any triggering events or circumstances, including impacts due to COVID-19, which would indicate an impairment of goodwill or indefinite-lived intangible assets.

Amortization expense of intangible assets was $45 million and $48 million for the three months ended January 31, 2021 and 2020, respectively.

Future amortization expense related to existing finite-lived purchased intangible assets for the remainder of fiscal year 2021 and for each of the next five fiscal years and thereafter is estimated below:
