Intangible assets related to our acquisitions are recorded at their fair value at the acquisition date. The change in intangible assets during the year ended
January 31, 2020
is primarily due to the acquisitions of Visual Compliance, CORE, STEPcom and BestTransport, partially offset by amortization. The balance of the change in intangible assets is due to foreign currency translation.
 
Intangible assets with a finite life are amortized into income over their useful lives. Amortization expense for existing intangible assets is expected to be
$257.0
million over the following periods:
$52.7
million for
2021,
$48.3
million for
2022,
$40.7
million for
2023,
$28.9
million for
2024,
$25.9
million for
2025
and
$60.5
million thereafter. Expected future amortization expense is subject to fluctuations in foreign exchange rates and assumes
no
future adjustments to acquired intangible assets.
