| (1) | In December 2016, the Company determined the tradename related to MIST Therapy was no longer an indefinite-lived intangible asset. The Company assigned a remaining useful of approximately 1.5 years, consistent with the Company’s other trademarks.
The Company performs its assessment of the recoverability of indefinite-lived intangible assets annually during the fourth quarter, or more frequently as impairment indicators arise, and it is based upon a comparison of the carrying value of such assets to their estimated fair values. The Company performed its most recent annual assessment during the four quarter of 2017, which resulted in no impairment charge. During the year ended December 31, 2016 the Company recorded an impairment charge of approximately $1.7 million to the MIST Therapy tradename and is included in impairment charges in the consolidated statement of operations. Amortization expense attributable to intangible assets for the years ended December 31, 2017 and 2016 was approximately $4.7 million and $3.5 million, respectively. Amortization expense in each of the five years and thereafter subsequent to December 31, 2017 related to the Company’s intangible assets is expected to be as follows (in thousands):
|  | Expected |
|  | Amortization |
|  | Expense |
2018 |  | $ | 3,748 |
2019 |  |  | 2,910 |
2020 |  |  | 2,885 |
2021 |  |  | 2,839 |
2022 |  |  | 2,835 |
Thereafter |  |  | 6,852 |
Total |  | $ | 22,069 |
