Goodwill is tested for impairment at the reporting unit level on an annual basis as of October 31, and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value. We use a discounted expected future cash flow methodology (income approach) to estimate the fair value of our reporting units for purposes of goodwill impairment testing.

During 2020, we recorded non-cash goodwill impairment charges of $185.8 million, which was primarily related to the write-off of all of GES’ goodwill due to the deteriorating macroeconomic environment related to the COVID-19 pandemic. Our remaining goodwill balance as of December 31, 2022 of $121.4 million pertains to our Pursuit business.

During 2022, we considered changes in macroeconomic facts and circumstances, particularly high inflation and the resulting rise in interest rates, which resulted in reduced fair values to our reporting units. As a result of our most recent impairment analysis performed as of October 31, 2022, the excess of the estimated fair value over the carrying value for our reporting units with reported goodwill (expressed as a percentage of the carrying amounts) under step one of the impairment test for the Banff Jasper Collection and the Alaska Collection was significant, and Glacier Park Collection was 17% and FlyOver was 19%. Accordingly, no impairment charges were recorded during 2022.

We will continue to closely monitor actual results versus expectations as well as whether and to what extent any significant changes in current events or conditions result in corresponding changes to our expectations about future estimated cash flows and discount rates. If our adjusted expectations of the operating results of our reporting units do not materialize, or the discount rate increases (based on increases in interest rates, market rates of return or market volatility), it is possible that we may be required to record goodwill impairment charges in the future, which may be material.

Our accumulated goodwill impairment was $415.5 million as of December 31, 2022 and 2021.
