Goodwill is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the Company’s goodwill might be impaired. The Company assesses qualitative factors to determine whether it is necessary to perform a quantitative assessment for each reporting unit. If the quantitative assessment is necessary, the Company will determine the fair value of each reporting unit. If the fair value of any reporting unit is less than the carrying amount, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The loss recognized will not exceed the total amount of goodwill allocated to the reporting unit. For the purpose of testing goodwill for impairment, the Company has identified its audio market clusters and esports as its reporting units. The goodwill valuations are Level 3 non-recurring fair value measurements.

Due to an increase in interest rates in the U.S. economy and a decrease in projected revenues, the Company tested its goodwill for impairment during the third quarter of 2023. As a result of the quantitative impairment test performed as of September 30, 2023, the Company recorded an impairment loss of $10.6 million related to the goodwill in its Philadelphia, PA market cluster. The impairment loss was primarily due to an increase in the discount rate due to certain risks associated with the U.S. economy and a decrease in the projected revenues used in the discounted cash flow analysis to estimate the fair value of our goodwill. The fair value of the goodwill in the Philadelphia, PA market cluster was estimated using an income approach. The income approach is based upon discounted cash flow analyses for the next ten years incorporating variables such as projected audio market revenues, projected growth rate for audio market revenues, projected audio market revenue shares, projected audio station operating income margins, and a discount rate appropriate for the audio industry. The key assumptions used in the discounted cash flow analyses are as follows:


Revenue growth rates		(9.3)% - 1.4%
Operating income margin		27.9%
Discount rate		10.0%
