Amortization expense of finite life intangible assets was $1.8 million and $2.2 million for the three-month periods ended June 30, 2020 and 2019, respectively and $3.5 million and $4.3 million for the six-month periods ended June 30, 2020 and 2019, respectively. Amortization over the next five years for finite life intangibles is expected to be $3.8 million for the remainder of 2020, $6.3 million in 2021, $5.4 million in 2022, $4.6 million in 2023, and $3.9 million in 2024.

During the six-month period ended June 30, 2019, the Company reassessed the useful lives of certain tradenames and determined that $3.9 million of their tradenames would have useful lives of 10 years now versus indefinite.

The Company completes an annual (or more often if circumstances require) goodwill and indefinite life intangible asset impairment assessment on October 1. As a part of its impairment assessment, the Company first qualitatively assesses whether current events or changes in circumstances lead to a determination that it is more likely than not (defined as a likelihood of more than 50 percent) that the fair value of a reporting unit or indefinite life intangible asset is less than its carrying amount. If there is a qualitative determination that the fair value is more likely than not greater than carrying value, the Company does not need to quantitatively test for impairment. If this qualitative assessment indicates a more likely than not potential that the asset may be impaired, the estimated fair value is calculated. If the estimated fair value is less than carrying value, an impairment charge is recorded.

In 2019, we performed a quantitative assessment and concluded each of our reporting units and indefinite life intangible assets had excess fair value over their carrying value. We determined negative macroeconomic factors resulting from the COVID-19 pandemic constituted a triggering event as of March 31, 2020 and based on a qualitative assessment determined that our goodwill and indefinite life intangible assets were not impaired. The Company did not identify any triggering events during the three month period ended June 30, 2020 that would require an interim impairment assessment of goodwill or intangible assets. The Company’s assumptions about future conditions important to its assessment of potential impairment of its goodwill and indefinite life intangible assets, including the impacts of the COVID-19 pandemic, are subject to uncertainty, and the Company will continue to monitor these conditions in future periods as new information becomes available, and will update its analyses accordingly.
