We perform an impairment assessment of our indefinite lived trade name intangible assets as of October 1 of each year. We continue to evaluate the use of our trade names and branding in our sales and marketing efforts. If there is a fundamental shift in the method of our branding in the future, we will assess the impact on the carrying amount of our trade name intangible assets to determine whether an impairment exists. If it is determined that an impairment has occurred, it would be recognized during the period in which the decision was made to make the fundamental shift.

Amortization expense related to definite-lived intangible assets was $2.2 million and $0.4 million for the three months ended March 31, 2021, and 2020, respectively.
