Goodwill, Impaired, Facts and Circumstances Leading to Impairment | Subsequent to our annual test date, we identified an indicator of impairment related to future anticipated revenues, which triggered an additional impairment test as of June 30, 2020 |  |  |  |  |  |  |
Goodwill, Impaired, Method for Fair Value Determination | For the GES impairment test, we used an independent, third-party valuation specialist to assist in the determination of fair value for the GES reporting unit. We used a combination of the Income Approach, using a discounted cash flow model, and the Market Approach, based on projected fiscal year 2021 results. |  |  |  |  |  |  |
