The increase in the gross carrying amount of other intangible assets as of January 31, 2018, compared to July 31, 2017, was due to the effect of currency fluctuations during the six-month period.
Amortization expense of intangible assets was $1,617 and $1,688 for the three months ended January 31, 2018 and 2017, respectively, and $3,310 and $3,583 for the six months ended January 31, 2018 and 2017, respectively. The amortization over each of the next five fiscal years is projected to be $6,578, $6,223, $5,217, $5,174 and $5,017 for the fiscal years ending July 31, 2018, 2019, 2020, 2021 and 2022, respectively.
