of this reporting unit using the income-based and market-based approaches described above. As a result of this assessment, the fair value of our Adventure reporting unit exceeded the related carrying value by approximately 11%, thus no impairment of goodwill was recorded.

Indefinite-Lived Intangible Assets

The following table summarizes the changes in indefinite-lived intangible assets:

Similar to the goodwill impairment assessment, Management performs an interim indefinite-lived intangible asset impairment assessment whenever events or circumstances make it more likely than not that an impairment may have occurred, such as a significant adverse change in the business climate. If the carrying value of the indefinite-lived asset is higher than its fair value, the asset is deemed to be impaired and the impairment charge is estimated as the difference.

The Company calculates the fair value of its indefinite-lived intangible assets using the income approach, specifically the relief-from-royalty method. The relief-from-royalty method is used to estimate the cost savings that accrue to the owner of an intangible asset who would otherwise have to pay royalties or license fees on revenues earned through the use of the asset. Internally forecasted revenues, which the Company believes reasonably approximate market participant assumptions, are multiplied by a royalty rate to arrive at the estimated net after tax cost savings. The royalty rate used in the analysis is based on an analysis of empirical, market-derived royalty rates for comparable intangible assets. The net after tax cost savings are discounted using the same weighted-average cost of capital discount rate developed for purposes of the Company's quantitative goodwill impairment test.

As described above, we determined that a triggering event had occurred during the quarter ended September 30, 2022, with respect to certain indefinite-lived intangible assets within our Adventure reporting unit, which required that we perform a quantitative assessment. We assessed the fair value of the Adventure reporting unit indefinite-lived intangible assets using the relief-from-royalty method described above. As a result of this assessment, the fair value of our Adventure reporting unit indefinite-lived intangible assets exceeded the related carrying value by approximately 14%, thus no impairment was recorded.

If we do not achieve the results reflected in the forecasted estimates utilized in our impairment assessments, or if there are changes to market assumptions, our valuation of the reporting unit, including related indefinite-lived intangible assets, could be adversely affected, and we may be required to impair a portion or all of the related goodwill, indefinite-lived intangibles, and other long-lived assets which would adversely affect our operating results in the period of impairment.

Trademarks classified as indefinite-lived intangible assets by brand as of September 30, 2022 and December 31, 2021, were as follows:
