Intangible Assets, including Goodwill Intangible Assets, including Goodwill
Intangible Assets, net at September 30, 2021 decreased $8.8 million from December 31, 2020 primarily due to $10.4 million of amortization expense and a $4.7 million decrease in the value of intangible assets denominated in a foreign currency as a result of foreign exchange rate fluctuations. These decreases were partially offset by $5.3 million of intangible assets recorded in connection with an asset purchase during 2021.
Goodwill at September 30, 2021 decreased $2.0 million from December 31, 2020 primarily as a result of foreign exchange rate fluctuations on goodwill denominated in a foreign currency.
