    The Company typically performs its goodwill impairment test during the third quarter of the year, unless certain indicators suggest earlier testing to be warranted. The COVID-19 pandemic has resulted in significant levels of ongoing volatility in the capital markets and presents heightened uncertainty surrounding the future impact to operations of the Company and its customers. Given these conditions, the Company identified this impact from the pandemic as a triggering event warranting interim tests for impairment as of March 31, June 30, and again as of September 30, 2020. Accordingly, the Company performed impairment tests and determined that there was no impairment of its goodwill, as the fair value of the Company's single reporting unit remained in excess of its carrying value. Although the Company utilizes quoted market prices when estimating fair value of the reporting unit for purposes of the quantitative impairment test, it also considers certain qualitative factors, including the concept of a control premium, which increases the fair value as compared to market capitalization. Other intangible assets are also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company also considered the impact of the COVID-19 pandemic as it pertains to other intangible assets, and determined that there was no indication of impairment related to other intangible assets as of September 30, 2020.
