Gross intangibles assets decreased by $3.5 million for the three months ended January 31, 2020. The decrease was attributable to $1.0 million of currency fluctuations and the write-off of $2.5 million of fully-amortized assets.

Amortization expense was $17.5 million and $3.7 million for the three months ended January 31, 2020 and 2019, respectively. Amortization expense for the next five years is expected to be $69.4 million in 2020, $67.0 million in 2021, $59.0 million in 2022, $56.2 million in 2023 and $52.9 million in 2024.

Definite lived intangible assets for the periods presented are subject to amortization and are being amortized using the straight-line method over periods that are contractually, legally determined, or over the period a market participant would benefit from the asset.
