As of both December 31, 2023 and 2022, goodwill totaled $51.9 million. We have selected June 30 as our annual goodwill impairment testing date. We performed a qualitative impairment test of our goodwill and concluded that, as of June 30, 2023, it was more likely than not that the fair value exceeded the carrying value and therefore goodwill was not impaired. As of December 31, 2023 and 2022, there were no indicators of impairment.

In connection with our marketing initiatives, we purchased the naming rights to the downtown Oklahoma City arena that is home to the Oklahoma City Thunder National Basketball Association franchise. Under the terms of the naming rights agreement, we committed to make payments escalating annually from $4.0 million in 2021 to $6.1 million in 2035. We also made a $1.5 million one-time payment in July 2021 to cover sponsorship rights leading up to the 2021-2022 season. Upon the conclusion of the initial term, the agreement may be extended upon the mutual agreement of both parties for an additional five-year period. The cost of the naming rights has been recorded as an intangible asset with an offsetting liability as of the date of the contract. The intangible asset is being amortized over the life of the agreement on a straight line basis that commenced in June 2021. The difference between the present value of the offsetting liability and actual cash payments is being relieved through sales and marketing expense using the effective interest method over the life of the agreement.

All of our intangible assets other than goodwill are considered to have definite lives and, as such, are subject to amortization. The following tables present the components of intangible assets within our consolidated balance sheets:


	December 31, 2023
	Weighted Average Remaining			Accumulated
	Useful Life	Gross		Amortization			Net
	(Years)
Intangibles:
Naming rights	12.8	$	60,199	$	(10,087	)	$	50,112
Total		$	60,199	$	(10,087	)	$	50,112


	December 31, 2022
	Weighted Average Remaining			Accumulated
	Useful Life	Gross		Amortization			Net
	(Years)
Intangibles:
Naming rights	13.8	$	60,199	$	(6,182	)	$	54,017
Total		$	60,199	$	(6,182	)	$	54,017

Amortization of intangible assets for the years ended December 31, 2023, 2022 and 2021 was $3.9 million, $4.0 million and $2.5 million, respectively. We estimate the aggregate amortization expense will be $3.9 million in 2024, and $3.9 million for each of 2025, 2026, 2027 and 2028, respectively.
