The following tables present certain information regarding our intangible assets as of December 31, 2020 and December 31, 2019. Amortizable intangible assets are being amortized on a straight-line basis over their estimated useful lives with no estimated residual values, which materially approximates the expected pattern of use.

Goodwill represents the excess of the purchase price over the fair value of the assets acquired and liabilities assumed of acquired companies. We test goodwill for impairment annually as of October 1 of each fiscal year or more frequently if events arise or circumstances change that indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value.

We evaluate goodwill at the reporting unit level by comparing the carrying value of each reporting unit to its fair value using a quantitative impairment test or qualitative assessment, as deemed appropriate. Under the qualitative assessment option, we first assess qualitative factors to determine whether the fair value of a reporting unit is not “more than likely” less than its

carrying value, which is commonly referred to as “Step 0”. If the fair value of the reporting unit is greater or if it is more likely than not that the fair value of the reporting unit is greater than its carrying value, goodwill is not considered impaired. For reporting units where we perform the quantitative process, we are required to compare the fair value of each reporting unit, which we primarily determine using an income approach based on the present value of discounted cash flows and a market approach, to the respective carrying value, which includes goodwill. If the fair value of the reporting unit is less than its carrying value, an impairment charge is recognized for the amount by which the carrying value exceeds the reporting unit’s fair value determined based on a quantitative test, not to exceed the total amount of goodwill allocated to that reporting unit.

Our annual goodwill impairment tests as of October 1, 2020 indicated estimated fair values were in excess of their carrying values for each of our reporting units that have goodwill balances.

We conduct impairment tests of our indefinite-lived assets annually in the fourth quarter of each fiscal year, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of an indefinite-lived asset is less than its carrying value or when circumstances no longer continue to support an indefinite useful life.

Our annual impairment tests as of October 1, 2020 indicated estimated fair values were more likely than not in excess of the carrying values for all of our remaining indefinite-lived intangible assets.

A substantial portion of our legacy U.K. Gaming reporting unit revenue comes from Ladbrokes Coral Group (acquired by Entain (formerly GVC Holdings PLC) in March 2018), which operates LBOs in the U.K. On April 1, 2019 the maximum stakes limit on fixed odds betting terminals was reduced from £100 to £2. As a result of this change, LBO operators began to rationalize their retail operations, which among other measures has included closure of certain LBO shops. Consequently, as of October 1, 2019, we concluded that an elevated risk of goodwill impairment existed for our legacy U.K. Gaming reporting unit as adverse changes in projections for future operating results or other key assumptions, such as projected revenue, profit margin, capital expenditures or cash flows associated with investments included in that reporting unit could lead to future goodwill impairments.

During the first quarter of 2020, the COVID-19 disruptions resulted in the widespread closures of LBO shops across the U.K., which, along with global economic uncertainty, contributed to further deterioration in business conditions from our 2019 annual goodwill test date. This had an adverse effect on our legacy U.K. Gaming reporting unit (part of our Gaming business segment), which necessitated performing a quantitative goodwill impairment test during the first quarter of 2020.

We performed this quantitative impairment test by comparing the fair value of our legacy U.K. Gaming reporting unit to its carrying value, including goodwill. The fair value of our legacy U.K. Gaming reporting unit was determined using a combination of both an income approach, based on the present value of discounted cash flows, and a market approach. Due to market volatility and limited market data points specific to the nature of our legacy U.K. Gaming reporting unit operations, we placed greater weight on the income approach than on the market approach. As a result of this analysis, during the first quarter of 2020 we recognized a partial impairment charge totaling $54 million, which is the amount by which the carrying value exceeded the estimated fair value. This impairment charge resulted in no tax benefit.

We used projections of revenues, profit margin, operating costs, capital expenditures and cash flows that primarily considered general economic and market conditions and estimated future results including the estimated impact of the COVID-19 disruptions. We used a range of different scenarios and derived estimated fair value based on an equal weighting of these scenarios to reflect the economic uncertainty resulting from the COVID-19 disruptions and the timing and magnitude of the economic recovery following the COVID-19 disruptions coupled with the impact of the regulatory change. The following ranges of the key estimates and assumptions were used in the discounted cash flow analysis:

•Revenue growth for FY 2021 between negative 9% and negative 20%, an average revenue growth for FY 2022 to FY 2027 between positive 3% and positive 5%, and terminal revenue growth rate of positive 2.0%;

In our market comparable analysis, we considered revenue and EBITDA multiples ranging from 2.1x to 2.7x and 5.7x to 7.5x, respectively, and ultimately selected multiples at the low end of the range.

Intangible assets with finite useful lives are amortized over two to fifteen years using the straight-line method, which materially approximates the pattern of the assets’ use. Factors considered when assigning useful lives include legal, regulatory and contractual provisions, product obsolescence, demand, competition and other economic factors.

We assess the recoverability of long-lived assets and intangible assets with finite useful lives whenever events arise or circumstances change that indicate the carrying value of an asset may not be recoverable. Recoverability of long-lived assets (or asset groups) to be held and used is measured by a comparison of the carrying value of the asset (or asset group) to the expected net future undiscounted cash flows to be generated by that asset (or asset group). The amount of impairment of other long-lived assets and intangible assets with finite lives is measured by the amount by which the carrying value of the asset exceeds the fair market value of the asset.
