[1] | In the fourth quarter of 2019, the Company met all of the assets held for sale criteria related to the divestitures of its inks product line and fragrances product line (excluding its essential oils product line). Goodwill of $8.4 million was allocated to those disposal groups and was determined to be fully impaired based on the estimated fair value of each of the disposal groups. In 2020, the fair value of the disposal groups decreased, which resulted in the previously allocated goodwill of $2.2 million to be reallocated to its respective financial reporting units. See Note 14, Divestitures, for additional information.
[2] | In 2021, the fair value of the disposal group increased, which increased the value of goodwill allocated to the disposal group by $0.8 million. See Note 14, Divestitures, for additional information.
